This Annual Report on Form 10-K includes statistical and other industry and market data that we obtained from industry publications and research, surveys and studies conducted by third parties. Industry publications and third-party research, surveys and studies generally indicate that their information has been obtained from sources believed to be reliable, although they do not guarantee the accuracy or completeness of such information.
Summary of Principal Risk Factors
The following is a summary of the principal factors that make an investment in our company speculative or risky. This summary does not address all of the risks and uncertainties that we face. Additional risk and uncertainties not presently known to us or that we presently deem less significant may also impair our business operations. Additional discussion of the risks summarized in this summary, and other risks that we face, can be found in Item 1A. Risk Factors section of this Annual Report on
Form 10-K, and should be carefully considered, together with other information in this Annual Report on Form 10-K and
our other filings with the Securities Exchange Commission, before making an investment decision regarding our common
stock. The forward-looking statements discussed above are qualified by these risk factors. If any of the following risks occur,
our business, financial condition, results of operations and future growth prospects could be materially and adversely affected.
1.We are a development-stage company without any approved products. The value of your investment is highly dependent on the success of our research and development programs, which carry numerous risks.
2
2.We have had a history of operating at significant losses and expect to continue to do so until we can successfully commercialize one or more of our product candidates, if ever. We may never achieve profitability.
3.We will need additional financing in order to finish developing and start commercializing one or more of our product candidates, if approved. Securing financing may be challenging and/or dilutive to our shareholders, and if we are unable to secure financing when needed, we may need to curtail our development programs.
4.The COVID-19 pandemic has adversely affected our business, for example, by impacting the initiation and conduct of our clinical trials, the work of our academic collaborators and contract manufacturing organizations, and aspects of our supply chain. Because of the ongoing and fluid nature of the pandemic, it will continue to affect our business.
5.Drug development is inherently risky with numerous scientific, technical, regulatory and other challenges. A promising drug candidate can fail at any time and for any number of reasons.
6.We are pursuing the development of our product candidates using novel mechanisms of action targeting indications for which there are no approved products. These include, for example, complement inhibition and inhibition of HtrA1 for GA; complement inhibition for autosomal recessive Stargardt disease; and gene therapy for RHO-adRP and BEST1-related IRDs. These approaches carry numerous scientific, regulatory and other risks.
7.We have not had any formal meetings with the FDA or the EMA regarding the results of the GATHER1 trial or our regulatory pathway for Zimura following GATHER1, and regulatory authorities may disagree with the design of or our conclusions from the GATHER1 trial, including our belief that it may serve as one of the two Phase 3 clinical trials required for approval by the FDA and EMA. The results of the GATHER2 trial may not replicate the results of the GATHER1 trial. We may need to conduct additional clinical trials or nonclinical studies for Zimura in order to obtain marketing approval.
8.Gene therapy is a novel area of disease treatment that is subject to numerous risks and uncertainties. We have no prior experience conducting clinical development of a gene therapy product.
9.We may discover safety issues with our product candidates due to known and currently unknown factors, which could hamper their further development.
10.Manufacturing our product candidates, including our gene therapies, is technically complex, expensive and time consuming. We may face issues with scaling up and validating the manufacturing process for Zimura. Issues with manufacturing can derail the further development or commercialization of our product candidates.
11.We face substantial competition from large pharmaceutical companies, smaller biotech companies and others.
12.To commercialize any of our product candidates, if approved, we will need to set up a sales and marketing infrastructure. The success of our commercialization efforts will depend in part on the degree of acceptance of our product candidates by patients, the medical community and payors.
13.We do not have any internal manufacturing facilities and rely heavily on our third-party contract manufacturers. They may have different business priorities than we do and may fail to meet our expectations or follow regulatory requirements, including cGMP requirements.
14.We do not have any internal laboratories and rely heavily on our third-party contract research organizations as well as our clinical trial sites and academic collaborators. They may have different priorities than we do and may fail to follow regulatory requirements, including GLP, GCP and other data integrity requirements.
15.If we choose to pursue a collaboration for the further development and potential commercialization of any of our product candidates, we may not be able to enter into a collaboration on favorable terms, or at all. Even if we are able to do so, the collaboration may not be successful.
16.We rely on patents to protect our proprietary position. We may not obtain the patent rights that we seek and/or we may not be able to exclude our competitors from relevant markets. We may be subject to litigation involving our patents or those of third parties.
3
17.We are highly dependent on our information security systems and those of third parties we work with. A cybersecurity incident may cause interruptions to the progress of our development programs and operations, financial or regulatory penalties and/or harm to our reputation.
18.We rely on a limited number of employees to conduct our operations, including supervising our outside vendors. The skills needed to advance our research and development programs and plan for eventual commercialization of our product candidates are highly specialized. We plan to hire additional qualified personnel to support the growth of our business. Hiring these personnel and retaining existing employees may be challenging.
19.We need to satisfy numerous regulatory requirements in order to secure marketing approval and reimbursement approval, if applicable, for any of our product candidates. These requirements differ across jurisdictions. Failure to satisfy and maintain those requirements can preclude us from commercializing our products.
20.We and any commercialization partners are subject to numerous healthcare laws and regulations governing our relationships with patients, healthcare professionals and third-party payors. Failure to comply with these requirements may adversely affect our business.
21.The reimbursement and payment regime for pharmaceutical products in the United States remains in flux, including as a result of the implementation of and litigation involving the Affordable Care Act. There are ongoing, and often bipartisan, efforts to reduce the prices of pharmaceutical products.

PART I
Item 1. Business
Overview and Our Strategy
We are a science-driven biopharmaceutical company focused on the discovery and development of novel treatment options for retinal diseases with significant unmet medical needs. We are currently developing both therapeutic product candidates for age-related retinal diseases and gene therapy product candidates for orphan inherited retinal diseases, or IRDs. We believe that both therapeutics and gene therapy serve important roles in drug development and providing potential treatment options for patients suffering from retinal diseases.
Our therapeutics portfolio consists of our clinical stage product candidate Zimura® (avacincaptad pegol), a complement C5 inhibitor, and our preclinical product candidate IC-500, a High temperature requirement A serine peptidase 1 protein, or HtrA1, inhibitor. We are currently targeting the following diseases with Zimura:
•geographic atrophy, or GA, which is the advanced stage of age-related macular degeneration, or AMD, and is characterized by marked thinning or atrophy of retinal tissue, leading to irreversible loss of vision; and
•autosomal recessive Stargardt disease, or STGD1, which is an orphan inherited condition characterized by progressive damage to the central portion of the retina, or the macula, and other retinal tissue, leading to loss of vision.
We are developing IC-500 for GA secondary to AMD and potentially other age-related retinal diseases.
Our gene therapy portfolio consists of two product candidates in preclinical development (IC-100 and IC-200) and several ongoing collaborative sponsored research programs, each of which uses adeno-associated virus, or AAV, for gene delivery. These AAV mediated gene therapy programs are targeting the following orphan IRDs:
•rhodopsin-mediated autosomal dominant retinitis pigmentosa, or RHO-adRP, which is characterized by progressive and severe bilateral loss of vision leading to blindness;
•IRDs associated with mutations in the BEST1 gene, including Best vitelliform macular dystrophy, or Best disease, which is generally characterized by bilateral egg yolk-like lesions in the macula, which, over time, progress to atrophy and loss of vision;
•Leber Congenital Amaurosis type 10, or LCA10, which is characterized by severe bilateral loss of vision at or soon after birth;
•autosomal recessive Stargardt disease; and
•IRDs associated with mutations in the USH2A gene, which include Usher syndrome type 2A, or Usher 2A, and USH2A-associated non-syndromic autosomal recessive retinitis pigmentosa.
We are developing IC-100 for RHO-adRP and IC-200 for BEST1-related IRDs.

Research and Development Pipeline
We have summarized the current status of our ongoing research and development programs in the table below.
*We have an option to exclusively in-license intellectual property resulting from ongoing sponsored research.
2020 Highlights and Our Strengths
In 2020, we achieved a number of significant company milestones, including the following:
•In June 2020, we completed and announced 18-month data from GATHER1, also known as OPH2003, an international, randomized, double-masked, sham controlled, multi-center clinical trial assessing the safety and efficacy of Zimura for the treatment of GA secondary to AMD. The 18-month data supported the previously announced 12-month data from this trial, which confirmed that Zimura met the prespecified primary endpoint in the trial in reducing the rate of GA growth in patients. The reduction in the mean rate of GA growth over 12 months using the square root transformation was 0.110 mm (p-value = 0.0072) for the Zimura 2 mg group as compared to the corresponding sham control group and 0.124 mm (p-value = 0.0051) for the Zimura 4 mg group as compared to the corresponding sham control group, indicating an approximate 27% relative reduction in the mean rate of GA growth over 12 months when compared with sham for both dose groups. This data was statistically significant. GATHER1 was designed to be a Phase 2b screening trial, with the potential to qualify as a pivotal trial depending on the magnitude and statistical significance of the potential benefit observed. Based on the 12-month data, we believe that the GATHER1 trial qualifies as the first of two Phase 3 trials typically required by the U.S. Food and Drug Administration, or FDA, for marketing approval of a pharmaceutical product. In light of the 12-month data, we changed the phase designation of the GATHER1 trial to a Phase 2/3 trial and we believe it qualifies as a Phase 3 clinical trial.
•In June 2020, we dosed the first patient in GATHER2, also known as ISEE2008, an international, randomized, double-masked, sham controlled, multi-center Phase 3 clinical trial assessing the safety and efficacy of Zimura for the treatment of GA secondary to AMD. We plan to enroll approximately 400 patients in this trial. We are continuing to recruit and enroll patients and expect to complete patient enrollment during the third quarter of 2021.
•In June 2020, we closed an underwritten public offering in which we sold 28,503,220 shares of our common stock and pre-funded warrants to purchase 1,914,280 shares of our common stock. Concurrently with the public offering, we sold 8,649,453 shares of our common stock in a private placement. The net proceeds from the public offering and private placement, after deducting underwriting discounts, placement agent fees and other offering expenses, was approximately $150.1 million.
•We continued to hire strategically to support key areas of our business, such as manufacturing, quality assurance and supply chain management, with a total of 22 full-time employees joining our team over the course of 2020. In response to the global COVID-19 pandemic and other current events, we increased our efforts to support the health and well-being and productivity of our employees and to undertake diversity, equity and inclusion initiatives.
6
We believe a number of factors provide us a competitive advantage in retinal drug development for therapeutics and gene therapies. These factors include:
•Broad and deep portfolio of product candidates and development programs. We have built a broad and deep portfolio of therapeutic and gene therapy product candidates and programs that we believe are scientifically compelling, target diseases for which there are high unmet medical needs, and provide significant market opportunities. For our gene therapies, we are focused on using AAV for gene delivery, which we believe is generally safe for the eye and holds tremendous promise for treating a number of IRDs for which there are no currently approved treatments.
•Collaborative relationships with global clinical trial sites, leading academic institutions and key leaders in the ophthalmic field. We have an extensive network of over 300 ophthalmic clinical trial sites worldwide with which we have worked. We have deep relationships with global retina thought leaders. We have developed collaborative relationships with several leading academic institutions in gene therapy research, including the University of Massachusetts Medical School, or UMMS, the University of Pennsylvania, or Penn, and the University of Florida, or UF.
•Our clinical experience and growing capabilities. Our team has significant experience in the efficient execution of large-scale clinical trials for retinal diseases, and we are leveraging that experience as we conduct GATHER2 and prepare for the potential clinical development of our gene therapy product candidates. We have built and are continuing to build our internal and external capabilities in various areas, such as manufacturing, analytical development, quality assurance and control, preclinical research and regulatory affairs.
Business Development and Financing Activities
Beginning in 2017, we pursued a business development strategy focused on evaluating various available technologies to treat ophthalmic diseases, particularly those in the back of the eye, and exploring opportunities to obtain rights to additional products and product candidates employing these technologies. Our efforts resulted in the expansion of our research and development pipeline, including the addition of IC-100, IC-200 and IC-500 and a number of collaborative gene therapy sponsored research programs.
As we continue the development of our product candidates and programs and evaluate our overall strategic priorities, we will continue to pursue selective business development and financing opportunities that advance us toward our strategic goals. We continue to explore potential collaboration and out-licensing opportunities for the future development and potential commercialization of our product candidates. In addition, we plan to continue to evaluate, on a selective and targeted basis, opportunities to potentially obtain rights to additional product candidates and technologies for retinal diseases, including technologies that may complement our existing product candidates and other strategic lifecycle initiatives.
For information about our follow-on public offerings that we completed in December 2019 and June 2020, please see the Liquidity and Capital Resources section of Management' s Discussion and Analysis of Financial Condition and Results of Operations set forth in Part I, Item 7 of this Annual Report on Form 10-K. We expect to continue to pursue capital raising transactions when they are available on terms favorable to us and if the opportunity advances our strategic goals.
Impact of COVID-19
Beginning in March 2020, the COVID-19 pandemic and measures taken to contain it have affected various aspects of our business and operations, including our clinical trials, our supply chain, our workforce and the work of our third-party contract manufacturers and academic collaborators. For example, in March 2020, we decided to delay the initiation of patient enrollment in our GATHER2 trial. Although we began patient enrollment for GATHER2 in June 2020, we and our clinical trial sites have implemented a number of changes to our clinical trial operations to protect the health and safety of our clinical trial participants and site staff. Additionally, many of our third-party contract manufacturers, academic research collaborators and contract research organizations have limited their operations and staff, which has resulted in delays to some of our manufacturing and research and development activities. In addition, shortages, delays and governmental restrictions arising from the COVID-19 pandemic have disrupted and may continue to disrupt the ability of our contract manufacturers and contract research organizations to source needed materials.
In March 2020, as a result of the COVID-19 pandemic, we instituted company-wide remote working and we expect to continue working remotely for the foreseeable future. We are continuing to monitor and support the health and well-being of our employees and their productivity as remote working continues.

For a more detailed discussion of the actual and potential impacts to us as a result of the COVID-19 pandemic, see the other sections of this Annual Report on Form 10-K, including Management's Discussion and Analysis of Results of Operations and Financial Position set forth in Part I, Item 7 and the Risk Factors set forth in Part I, Item 1A.
Eye Diseases
Eye diseases can be caused by many factors and can affect both the front or back of the eye. In more severe cases, eye diseases can result in total loss of vision. In the developed world, the most common eye diseases that can result in total loss of vision are those affecting the retina and optic nerve, including AMD, diabetic retinopathy and glaucoma. These diseases deprive patients of their sight and, as a result, impair their ability to live independently and perform daily activities. Any improvement in vision, or even a slowing of the rate of progression of vision loss, has a tremendous impact on the quality of life of people with impaired vision. There are many other eye diseases that are less common but still represent an unmet medical need, particularly orphan IRDs that are associated with mutations in a single gene, referred to as monogenic, that lead to retinal degeneration and vision loss, generally in younger patients. We believe that these disease areas present several potential opportunities for ophthalmic drug development. A 2014 report from Prevent Blindness, a patient advocacy group, estimated that the total real annual costs in the United States related to eye diseases and vision problems expressed in constant 2014 dollars would increase from $145 billion in 2014 to $376 billion by 2050.
Age Related Macular Degeneration and Geographic Atrophy
AMD is an age-related disease characterized by progressive degenerative abnormalities in the macula, a small area in the central portion of the retina responsible for central vision. AMD is characteristically a disease of the elderly and is the leading cause of visual loss in individuals over 50 years of age in developed countries. Based on a 2016 epidemiology paper published in Eye and Vision, we estimate that currently approximately 11 million individuals in the United States and 170 million individuals worldwide have a form of AMD. Because of increasing life expectancy in developed and developing countries, the elderly population is expected to grow significantly in coming decades. Projections based on U.S. Census Bureau data suggest that the number of Americans over the age of 65 will more than double to approximately 80 million by the middle of this century. In the absence of adequate prevention or treatment measures, the number of cases of AMD with visual loss is expected to grow in parallel with the aging population, leading to a major public health challenge with significant socioeconomic implications.
AMD, at its early stages, presents with abnormalities in the retinal pigment epithelium, or the RPE, and yellow-white deposits under the RPE known as drusen, which generally become larger and more numerous as AMD progresses. The RPE is a layer of cells within the retina on which photoreceptors, the cells in the retina that are responsible for capturing light and converting it to electrochemical signals to the brain, are dependent for nutrients, waste disposal and other needs. As the disease progresses with age to the advanced stage, it generally progresses as either the non-neovascular or dry form of AMD or the neovascular or wet form of the disease. In the dry form of AMD, the eventual loss of photoreceptors, RPE cells and associated capillary blood vessels in the macula results in marked thinning and/or atrophy of retinal tissue. This advanced stage of dry AMD is called GA. In the wet form of AMD, abnormal new blood vessels originate beneath the retina, in a layer called the choroid, and invade into the overlying retinal layers, through a process called choroidal neovascularization, or CNV. The macula of patients diagnosed with the wet form of AMD, who are usually treated with currently approved standard of care anti-vascular endothelial growth factor, or anti-VEGF, therapies, can continue to atrophy resulting in GA, which suggests that in many AMD patients, regardless of whether they have the dry or the wet form, the final anatomic outcome leading to loss of vision is GA.
GA is a significant cause of bilateral, irreversible and severe loss of functional vision. Many individuals with GA experience dark spots in their field of vision, referred to as scotoma, even if their central vision remains normal. As a result, GA has a major impact on the functional vision, quality of life, and independence of affected individuals. The median time for development of central GA from the time of diagnosis is two and a half years with the condition expected to develop in the fellow eye within approximately seven years. Based on a comprehensive epidemiology study published in 2004 in Archives of Ophthalmology, we estimate that there are currently approximately 1.5 million people in the United States with GA. Furthermore, based on a study published in 2015 in the American Journal of Ophthalmology, we estimate that approximately 159,000 people in the United States develop GA each year. Although anti-VEGF therapy is available for treatment of wet AMD, no FDA or European Medicines Agency, or EMA, approved treatment is currently available for GA.
The absence of treatment options for GA and many other stages of AMD represents an area of urgent unmet medical need and a major public health concern for the expanding elderly population.

Inherited Retinal Diseases
IRDs are a group of eye disorders caused by one or more inherited gene mutations that result in lack of functional proteins necessary for normal vision. Generally, IRDs are severe and progressive and will result in vision loss or blindness, either at birth or in early childhood, or gradually over time. IRDs are generally orphan diseases, meaning that these diseases affect fewer than 200,000 individuals in the United States. Partially due to their orphan nature, there are no approved treatment options available for most IRDs. Recently, gene therapies have emerged as potential therapies for monogenic IRDs, where a mutation to a single gene has been identified as the cause.
Humans generally inherit a complete set of genes from each of their parents, and therefore have two copies, or alleles, for each gene, either of which may carry a mutation, and either, or both, of which may be expressed in particular cells throughout the body. An inherited condition is referred to as autosomal recessive when the subject must inherit mutated alleles from each parent for the condition to manifest. An inherited condition is referred to as autosomal dominant when the subject must only inherit one mutated allele from either parent for the condition to manifest. The predominant or standard, non-mutated form of a gene is referred to as the wildtype form, and the protein resulting from expression of the wildtype gene is referred to as wildtype protein. In autosomal recessive conditions, because both alleles for a particular gene carry a mutation, the subject cannot produce any wildtype protein, and instead the proteins that are expressed, if any, have either limited or no function. In autosomal dominant conditions, a number of factors may contribute to the condition:
•a subject may express only the mutant allele and not the wildtype allele, resulting in production of only protein with limited or no function and not the wildtype protein;
•a subject may be expressing both alleles, but because of the mutation on one of the alleles, the amount of functional protein may not be sufficient; or
•the protein expressed by the mutant allele may be toxic to the cells in which it is produced.
Stargardt Disease
Stargardt disease is an IRD that causes progressive damage to the macula and retina, leading to loss of vision in children and adolescents. The most common form of Stargardt disease is STGD1, the autosomal recessive form. STGD1 is caused by mutations in the ABCA4 gene, which is responsible for making a protein that helps to clear byproducts resulting from the visual cycle from inside photoreceptor cells in the eye.
Multiple sources, including the National Eye Institute and Genetics Home Reference, both of which are affiliated with the U.S. National Institutes of Health, or NIH, estimate the prevalence of Stargardt disease to be between 1 in 8,000 and 1 in 10,000, implying that in the United States and the EU5, which consists of France, Germany, Italy, Spain and the United Kingdom, the five major market countries for pharmaceutical treatments in Western Europe, on a combined basis there are currently a total of 62,000 to 77,000 affected persons. There are currently no therapies approved by the FDA or EMA to treat Stargardt disease. The FDA has recognized Stargardt disease as an orphan disease, with several treatments in development having received orphan drug designation from the FDA.
Rhodopsin-Mediated Autosomal Dominant Retinitis Pigmentosa
RHO-adRP is a form of retinitis pigmentosa, or RP. RP is the most prevalent IRD and is typically characterized by the initial degeneration of the rod photoreceptors, which are responsible for low light vision and peripheral vision. The degeneration of the rod photoreceptors over time leads to the degeneration of the cone photoreceptors, which are the photoreceptors in the central part of the retina that are responsible for color and sharp vision. This degeneration causes night blindness and severe and progressive visual impairment. Although often diagnosed during adolescence or young adulthood, most RP patients become legally blind by age 40.
Rhodopsin is a biological pigment found in the rod photoreceptors that is extremely sensitive to light and thus is crucial for low light vision. There are more than 150 identified mutations in RHO, the gene that encodes for rhodopsin. The presence of a mutated RHO gene is linked to the occurrence of RHO-adRP.
Based on disease prevalence rates contained in a study published in the Archives of Ophthalmology in 2007, we estimate that in the United States and EU5 on a combined basis, there are a total of approximately 11,000 affected persons with RHO-adRP. There is currently no FDA or EMA approved therapy to treat RHO-adRP.
9
BEST1-Related IRDs
The BEST1 gene encodes for a multifunctional protein known as bestrophin-1, or BEST1, which regulates chemical transport and signaling in RPE cells and helps maintain homeostasis in the subretinal space, the space between the photoreceptors and the RPE. The most common BEST1-related IRD is Best disease, which is generally autosomal dominant and generally affects individuals in both eyes. In Best disease, the lack of functional BEST1 protein results in the formation of egg yolk-like lesions in the macula that, over time, progress to macular atrophy and permanent loss of vision. In addition, because there are over 200 known mutations in the BEST1 gene, there are other BEST1-related IRDs being studied, including autosomal recessive forms.
Based on disease prevalence rates contained in a study published in Ophthalmic Genetics in 2017, we estimate that in the United States and EU5 on a combined basis, there are a total of approximately 10,000 to 40,000 affected persons with BEST1-related IRDs, the substantial majority of whom we believe have the autosomal dominant form of Best disease. There are currently no FDA or EMA approved therapies to treat any BEST1-related IRD.
Leber Congenital Amaurosis Type 10
Leber Congenital Amaurosis, or LCA, is an IRD that manifests at birth or early in childhood. It is characterized by early onset of vision loss in children leading to blindness. Affected individuals often manifest symptoms such as roving eye movements, deep-set eyes and sensitivity to bright light. There are multiple types of LCA, which are associated with mutations in different genes. The most common type is LCA10, which is caused by mutations in the CEP290 gene. Mutations in the CEP290 gene are believed to lead to the abnormal function and potentially loss of photoreceptor cells.
Based on disease prevalence rates contained in a study published in the American Journal of Human Genetics in 2006, we estimate that in the United States and EU5 on a combined basis, there are a total of approximately 2,700 to 4,100 affected persons with LCA10. There is currently no FDA or EMA approved therapy to treat LCA10.
USH2A-Related IRDs
The USH2A gene encodes for a protein called usherin. Usherin is believed to be important in the development and maintenance of cells in the retina and the inner ear. There are two principal IRDs associated with mutations in the USH2A gene: Usher 2A and USH2A-associated nonsyndromatic autosomal recessive retinitis pigmentosa. Usher 2A is an autosomal recessive syndrome characterized by hearing loss from birth and progressive vision loss, due to RP, that begins in adolescence or adulthood. USH2A-associated nonsyndromatic autosomal recessive retinitis pigmentosa is a genetic condition that manifests as vision loss without associated hearing loss.
Based on a study published in Experimental Eye Research in 2004, we estimate that in the United States and EU5 on a combined basis, there are a total of approximately 20,000 to 62,000 affected persons with USH2A-related IRDs. There are currently no FDA or EMA approved therapies to treat Usher 2A or USH2A-associated nonsyndromatic autosomal recessive retinitis pigmentosa.
Zimura
We are currently developing our product candidate Zimura, a C5 complement inhibitor, for the treatment of two ophthalmic conditions: GA secondary to AMD and STGD1. In April 2020, we received fast track designation from the FDA for Zimura for the treatment of GA secondary to dry AMD. Zimura is a chemically-synthesized, pegylated RNA aptamer. Aptamers are short molecules made up of a single stranded nucleic acid sequence or an amino acid sequence. The specific three-dimensional structure of an aptamer, which results from its specific sequence, allows it to bind molecular targets with high selectivity and specificity. Zimura is a pegylated aptamer, which means that polyethylene glycol, or PEG, a common biochemical compound attached to drugs to increase their duration of action in the human body and to decrease immune response, is linked to the chemically-synthesized strand of RNA.
The Complement System and Its Potential Role in AMD and STGD1
The complement system consists of a series of proteins that are involved in the defense of the body against infectious agents, or pathogens, and other foreign proteins. The complement system modulates a variety of immune and inflammatory responses to these pathogens and foreign proteins. Under normal circumstances, complement proteins, together with antibodies and white blood cells, act beneficially to protect the body by removing the pathogens and foreign proteins, along with other cellular debris. The complement system is generally tightly regulated, achieving the proper balance of activation and inhibition
10
depending on the body’s requirements. Poorly regulated or aberrant activation of the complement system, without a balanced or proportional inhibition of complement proteins, may result in a variety of pathological conditions. For example, in a study published in Histology and Histopathology in 2012, researchers found that human retinal drusen deposits, which are the hallmark of AMD, contained components of complement proteins.
The complement system is generally activated via one of three biological pathways commonly referred to as the classical pathway, the alternative pathway and the lectin pathway. These pathways eventually converge with the generation of an enzyme known as C3 convertase. C3 convertase cleaves, or separates, a serum protein called C3, into C3a and C3b. C3b is an important element of the body’s immune system, as it binds to pathogens and makes them susceptible to destruction by white blood cells. C3b also cleaves complement protein C5. The cleavage of C5 results in the formation of the terminal complement fragments C5a and C5b. A study published in the Journal of Biological Chemistry in 2015 concluded that C5a primes RPE cells for inflammasome activation in the presence of waste products from the visual cycle. Inflammasomes are intracellular protein structures that lead to cell death. Other studies have shown the presence of inflammasomes inside the RPE cells of post-mortem eyes of patients with GA. Formation of C5b, in combination with serum proteins C6, C7, C8 and C9, leads to the generation of C5b-9, referred to as membrane attack complex, or MAC, which has been shown to cause cell death. In particular, various studies have shown that MAC, together with the presence of lipofuscin, a yellow-brown waste byproduct from the visual cycle that is commonly found in the RPE cells of AMD patients, interferes with the proper functioning of RPE cells, leading to their dysfunction and death.
A simplified illustration of the complement system and the relationships between the complement proteins appears below:
Although the causes of AMD are not completely understood—in addition to advanced age, there are environmental and genetic risk factors that contribute to the development of AMD including ocular pigmentation, dietary factors, a positive family history for AMD, high blood pressure and smoking—a body of recent scientific literature suggests that complement system activation may also contribute to the pathogenesis of AMD. A study published in the Journal of Immunology in 2015 concluded that MAC accumulation in RPE cells leads to mitochondrial damage and cellular dysfunction, which we believe eventually leads to RPE cell death. Additionally, a study published in the American Journal of Ophthalmology in 2002 described the presence of MAC in post-mortem human donor eyes with dry AMD and GA. We believe these findings suggest that inhibition of the complement system, especially an inhibitor that prevents the cleavage of C5 into C5a and C5b, could prevent RPE cell death and potentially other pathological causes of AMD.
11
The pathogenesis of STGD1, which is caused by a mutation in the ABCA4 gene, also may involve activation of the complement system. With a defective copy of the ABCA4 protein, waste byproducts that a normal ABCA4 protein would otherwise help to clear accumulate in the RPE. Waste byproducts that accumulate in the RPE are referred to as bisretinoids. We believe that the accumulation of bisretinoids in RPE cells leads to activation of the complement system and the accumulation of MAC. In RPE cells, MAC is normally cleared by lysosomes, which are organelles within cells responsible for waste degradation and disposal. Bisretinoid accumulation leads to lysosomal dysfunction, potentially preventing the clearance of MAC. MAC accumulation also negatively impacts energy production by mitochondria inside RPE cells. Bisretinoid and MAC accumulation may lead to RPE cell deterioration and contribute to the subsequent loss of photoreceptor cells, leading to a decrease in vision over time.
In April 2017, Proceedings of the National Academy of Sciences, or PNAS, published a study reporting on the effects of complement system modulation in the RPE of a mouse model of Stargardt disease. The researchers injected recombinant AAV containing the coding sequence for CRRY, a protein that inhibits complement system activation, into albino ABCA4 mutant mice, which led to a two-fold reduction in the accumulation of bisretinoids and a 30% increase in the number of photoreceptor nuclei at one year. The study findings indicate that the inhibition of complement activation in the albino ABCA4 mutant mice leads to healthier RPE cells as compared to RPE cells of untreated mice. Researchers at Duke University published a 2013 paper in Investigative Ophthalmology & Visual Science, in which they found in an in vitro experiment that RPE cell damage resulting from the combination of complement system activation and visual cycle waste was more damaging than either component individually. When complement factor C5 was blocked, there was a significant improvement in RPE cell viability in vitro. Based on the data from these in vitro and in vivo experiments, we believe molecules involved in the inhibition or regulation of the complement system and MAC activation are prime targets for therapeutic intervention in STGD1.
Zimura is designed to target and inhibit the cleavage of complement protein C5 and the formation of the terminal fragments, C5a and C5b. By inhibiting the formation of complement system terminal fragments, Zimura may decrease the activation of inflammasomes and decrease the formation of MAC, thereby potentially avoiding or slowing the degeneration of RPE cells and providing the rationale as a potential therapy for various stages of AMD and STGD1.
Our Zimura Clinical Programs
In 2020, we completed the GATHER1 trial and we currently have two clinical trials for Zimura ongoing. The following is a brief description of these trials and their current status:
•GATHER1 (GA secondary to AMD - completed): an international, randomized, double-masked, sham controlled, multi-center Phase 2/3 clinical trial evaluating the safety and efficacy of Zimura for the treatment of GA secondary to AMD. We enrolled 286 patients in this trial across multiple treatment groups, including various Zimura doses and sham control groups, and patients were treated and followed for 18 months. In October 2019, we announced positive 12-month data from this trial and in June 2020, we completed this trial and announced 18-month data from this trial, which supported the 12-month data. In this trial, the treatment effect was observed as early as 6 months, with an increase in the absolute difference of the mean change in GA growth for treatment with either Zimura 2 mg or Zimura 4 mg, as compared to sham, at each subsequent time point, suggesting the progressive benefit of continuous treatment with Zimura.
•GATHER2 (GA secondary to AMD - ongoing): an international, randomized, double-masked, sham controlled, multi-center Phase 3 clinical trial evaluating the safety and efficacy of Zimura for the treatment of GA secondary to AMD. We plan to enroll approximately 400 patients in this trial, who will be randomized into Zimura 2 mg and sham control groups. The prespecified primary efficacy endpoint will be the mean rate of change in GA growth over 12 months, as measured by fundus autofluorescence based on readings at three time points: baseline, month 6 and month 12, calculated using the square root transformation of the GA area, which is the same as that for the GATHER1 trial. We plan to treat and follow all patients for 24 months. We are continuing to recruit and enroll patients and expect to complete patient enrollment during the third quarter of 2021.
•STAR (also known as OPH2005; STGD1 - ongoing): an international, randomized, double-masked, sham controlled, multi-center Phase 2b clinical trial evaluating the safety and efficacy of Zimura for the treatment of STGD1. We initially enrolled 95 patients in the this trial, all of whom have completed their scheduled visits as of September 2020. In July 2020, we reopened enrollment in this trial in the United States. We plan to enroll approximately 25 additional patients, with the goal of enrolling a total of approximately 120 patients. We have been and will remain masked until results are analyzed for all the patients in this trial.
12
In addition to the GATHER1 trial, we have completed multiple clinical trials evaluating various doses of Zimura in age-related retinal diseases, including:
•OPH2001, a Phase 1/2a clinical trial of various doses of Zimura monotherapy for the treatment of GA, with a total of 47 patients enrolled;
•OPH2000: a Phase 1/2a clinical trial of various doses of Zimura administered in combination with Lucentis® (ranibizumab), an anti-vascular endothelial growth factor, or anti-VEGF, agent, for the treatment of wet AMD, with a total of 60 patients enrolled;
•OPH2007, a Phase 2a clinical trial of various doses of Zimura administered in combination with Lucentis for the treatment of wet AMD, with a total of 64 patients enrolled and treated; and
•OPH2002: a very small Phase 2a clinical trial of Zimura in combination with anti-VEGF agents for the treatment of idiopathic polypoidal choroidal vasculopathy, or IPCV, in patients for whom anti-VEGF monotherapy had failed.
Over 350 patients have been treated with Zimura in these completed clinical trials, with treatment durations extending up to 18 months. All doses of Zimura administered in these trials were well-tolerated, with only a single occurrence of an adverse event, mild subcapsular cataract, assessed to be drug-related by participating investigators.
Although we are currently not pursuing development of Zimura in wet AMD or IPCV, we may evaluate opportunities for further development of Zimura in these indications, earlier stages of AMD and other age-related retinal diseases.
Zimura is administered by intravitreal injection. Patients receiving intravitreal injections typically receive topical numbing drops or injection of a numbing agent prior to the injection. The administering physician also typically rinses the ocular surface with an antiseptic solution. By injecting the active agent into the vitreous cavity, the physician delivers the agent in close vicinity to the active disease site while minimizing the risk for systemic exposure to non-ocular tissues.
An intravitreal injection results in elevation of intraocular pressure, or IOP, which is usually transient. In our clinical trials, the IOP is monitored after each intravitreal injection. Certain of the dosing regimens we are evaluating in STAR involve multiple intravitreal injections administered on the same day. Based on our clinical experience to date, we have not seen any meaningful or sustained increase in IOP in clinical trials involving multiple intravitreal injections on the same day, and we believe that multiple intravitreal injections likely could be delivered safely on the same day.
Our Zimura clinical experience to date, as well as our ongoing clinical trials for Zimura, are described in greater detail below.
Zimura - GA and Dry AMD Trials
GATHER1: Completed Clinical Trial Assessing the Safety and Efficacy of Various Doses of Zimura for GA Secondary to AMD
In October 2019, we announced 12-month data from the GATHER1 trial and in June 2020, we completed and announced 18-month data from this trial. The primary efficacy analysis was performed at the 12-month time point. Pursuant to the clinical trial protocol, patients continued to be treated and followed through month 18. We remained masked regarding the treatment group to which each individual patient was randomized throughout the duration of the trial. Following the conclusion of the trial, we have continued to review and analyze the unmasked, individual patient data from this trial.
Trial Design and Enrollment
A total of 286 patients were enrolled across two parts of the trial.
Part 1. In Part 1 of the trial, 77 patients were randomized into one of three treatment groups in a 1:1:1 ratio as follows:
| Cohort | Zimura 1 mg | Zimura 2 mg | Sham | |||||||||||||||||
| Patients | 26 | 25 | 26 | |||||||||||||||||
In Part 1 of the trial, Zimura was administered by monthly intravitreal injections, while patients in the sham control group received monthly sham injections. In 2017, based on the announcement of positive data from a competitor studying a different complement inhibitor in a Phase 2 clinical trial in GA and following review of additional third-party clinical trial data and
13
further statistical analysis, we modified the trial design to change the total number of patients to be enrolled, to change the primary efficacy endpoint from a vision endpoint to an anatomic endpoint, to shorten the time point for the primary efficacy analysis to month 12 and to include a Zimura 4 mg dose group. The patients who were enrolled in Part 1 remained in the trial following these modifications and we remained masked regarding the treatment group to which each patient was randomized.
Part 2. In Part 2 of the trial, we enrolled 209 additional patients, who were randomized into one of three treatment groups in a 1:2:2 ratio as follows:
| Cohort | Zimura 2 mg | Zimura 4 mg | Sham | |||||||||||||||||
| Patients | 42 | 83 | 84 | |||||||||||||||||
In Part 2 of the trial, patients in the Zimura 2 mg group received one intravitreal injection of Zimura 2 mg and one sham injection at each monthly visit; patients in the Zimura 4 mg group received two intravitreal injections of Zimura 2 mg at each monthly visit; and patients in the sham control group received two sham injections at each monthly visit. In its current formulation, doses of Zimura above 2 mg would require more than one intravitreal injection.
The primary efficacy endpoint was the mean rate of growth of GA over 12 months, while secondary efficacy endpoints evaluated mean changes in patients' visual acuity in different lighting conditions over the same period.
Key Inclusion and Exclusion Criteria
In order to determine eligibility to participate in the trial, the location and size of each patient’s GA was assessed using fundus autofluorescence, or FAF, images. FAF is a common imaging technique used by retina specialists for photographing and documenting the size of GA present in the back of the eye, or fundus. Autofluorescence refers to the natural emission of light by biological structures. In FAF images, areas of atrophy are characterized by lower autofluorescence. An independent masked reading center assessed FAF images throughout the trial, including at baseline to determine eligibility.
The fovea is the central portion of the macula where visual acuity is the highest. We sought to enroll patients whose GA was located, in whole or in part, within 1500 microns of the foveal center but that did not enter the foveal center. A disc area is the size of the area of the retina where a standard sized optic nerve emerges, which is generally accepted to be 2.5 mm2. We sought to enroll patients with a total GA area of between 1 and 7 disc areas (or 2.5 mm2 to 17.5 mm2) inclusive. If the GA was multifocal, meaning it was not continuous and had multiple locations, at least one focal lesion needed to measure at least 0.5 disc areas (or 1.25 mm2). Each patient's best corrected visual acuity, or BCVA, was also assessed using the Snellen equivalent scale, which equates the detail a patient can see at a distance of 20 feet with the detail an individual with 20/20 vision can see at a greater distance. For example, a patient with 20/50 vision sees at 20 feet what a person with 20/20 vision would see at 50 feet. To be eligible to participate in the trial, patients' BCVA in the study eye was initially required to be between 20/25 and 20/100 inclusive during Part 1 of the trial. As part of the modifications we made for Part 2 of the trial, we expanded the inclusion criteria to include patients whose BCVA in the study eye was between 20/25 and 20/320 inclusive. BCVA on the Snellen equivalent scale can be equated to a number of letters of vision on the Early Treatment of Diabetic Retinopathy Study, or ETDRS, chart. BCVAs of 20/25, 20/100 and 20/320 on the Snellen equivalent scale are equivalent to 80 ETDRS letters, 50 ETDRS letters and 25 ETDRS letters, respectively.
Patients were stratified across treatment groups by baseline BCVA, baseline GA area and the baseline pattern of autofluorescence at the margins of the GA lesion, referred to as the junctional zone. Stratification for baseline characteristics is a method for allocating patients to treatment groups to ensure that there are approximately the same ratio of patients with a given baseline characteristic in each treatment group as the overall randomization ratio. For vision, patients were stratified based on whether their vision was above or below 50 ETDRS letters. For GA area, patients were stratified based on whether their GA area was above or below 4 disc areas. For autofluorescence pattern, patients were stratified based on several well-known patterns that have been described in the scientific literature.
As part of the modifications for Part 2 of the trial, we amended the clinical trial protocol to provide that patients in any arm of the trial who developed CNV in the study eye would be removed from the trial and any future study treatments and assessments, since we did not believe, at the time of the modifications, that GA lesions for patients with CNV in the study eye could be reliably measured with FAF images.
Additionally, patients who had a prior history of intravitreal treatment for any indication in either eye were excluded, as well as patients with any ocular condition in the study eye that could affect central vision or otherwise confound assessments.
Baseline Characteristics
We collected baseline characteristics for all patients participating in the trial. GA area was measured based on the area of GA in square millimeters (mm2). Reported scientific literature indicates that the rate of GA growth may be dependent on the
14
baseline lesion size, with larger GA lesions generally growing faster than smaller lesions, subject to an overall plateau effect as the GA grows to consume almost the entire macula. For this reason, patients were stratified in this trial based on their baseline lesion size. To further mitigate for the impact of baseline lesion size on the growth of GA, a square root transformation was performed. It is reported in the scientific literature and accepted in the field that using the square root of the lesion size for calculating the mean change in size over time mitigates for the impact of the baseline lesion size. We used the square root transformation of GA area, measured in millimeters (mm), to perform the assessment of the primary efficacy endpoint in the GATHER1 trial.
Although GA can be associated with profound and irreversible vision loss, the vision loss that patients experience is not necessarily linearly correlated to the progression of GA. The specific location of the GA within patients' retinas can affect patients' vision differently. In general, patients whose GA expands into the fovea experience vision loss that is disproportionate to the vision loss experienced by patients whose GA does not expand into the fovea. Further, patients with GA may demonstrate good visual acuity but poor functional vision if their GA results in dark spots, referred to as scotomas, in their central visual field. Patients with scotomas may be able to read a vision chart letter-by-letter, especially if their GA has not entered the fovea, but they may have trouble reading a paragraph of text or driving, as these activities of daily living draw upon a field of vision that is broader than a single point of focus. For this reason, and based on our prior interactions with the FDA, we believe the efficacy assessment that is most likely to demonstrate clinical relevance for an investigational product across a heterogeneous GA patient population is reduced rate of growth in GA. If an investigational product can slow the growth of GA, it has the potential to preserve, or slow the loss of, functional vision for patients whose GA is expanding into critical areas of their central visual field, which would be clinically meaningful.
In addition to baseline GA area, it has been reported in the scientific literature that GA that is non-subfoveal, or that has not impacted the foveal center, is positively correlated with a higher rate of GA area progression and growth. We believe that once a GA lesion expands into the fovea, the rate of growth may be slowed. In addition, once GA expands to encompass the central fovea, additional progression can be limited in the central region of the retina, with any continued expansion occurring predominantly in the outer part of the retina.
In addition to measuring the area of GA, we followed patients for changes in their vision (BCVA), as measured both at a standard light level, or luminance, and lower light level, or low luminance (LL BCVA), measured in each case by ETDRS letters. Testing for visual acuity serves as an important safety assessment to assure that the decrease in visual acuity in the Zimura treatment groups was not different from the sham control groups. Because we believe that BCVA is not the optimal assessment to evaluate the impact of GA on patients’ functional vision, we included vision in the prespecified statistical analysis as a secondary, and not as a primary, endpoint.
For patients within each treatment group, where a numerical measurement was collected, we calculated the mean and standard deviation, or SD, for each measurement. SD is a statistical measure of the variability of a particular measurement within a patient population. Generally, two-thirds of all patients fall within approximately one SD, plus or minus, of the mean for any particular measurement.
The baseline characteristics are presented below for each treatment group in each Part of the trial. These baseline characteristics include the ITT, or intent-to-treat, population, which includes all patients who were randomized in the trial and who received at least one dose of study drug in the relevant treatment group. Based on these data, we believe that the baseline characteristics were generally balanced across the treatment groups.

Statistical Analysis for Efficacy Measures
GATHER1 was designed as a Phase 2b screening trial based on the criteria described by Drs. Thomas Fleming and Barbara Richardson in their publication regarding clinical trial design in the context of microbicides for the prevention of HIV in the Journal of Infectious Disease in 2004. A screening trial uses the same primary efficacy endpoint as an anticipated Phase 3 clinical trial that would be used to support potential marketing approval. However, screening trials generally have a considerably smaller sample size than the anticipated Phase 3 clinical trial. Because it is particularly important to avoid false negative outcomes in a screening trial, screening trials may have higher false positive error rates than would typically be allowed in a Phase 3 trial.
A Phase 2b screening trial has three possible outcomes:
•If the estimated effect size indicates low levels of benefit, the experimental intervention would be judged as not plausibly more efficacious than the sham control, and should be discarded in its current dosage in the indication evaluated;
•If the estimated effect size is moderate but clinically relevant, with a relatively low likelihood of being achieved (for example, a probability of less than 10%) if there truly were no effect, the experimental intervention would be judged as plausibly more efficacious than the sham control and should be evaluated definitively in subsequent Phase 3 clinical trials; or
•If the estimated effect size is clinically relevant and reaches the traditional threshold for statistical significance, as was the case in the GATHER1 trial for both the Zimura 2 mg and Zimura 4 mg dose groups as compared to the corresponding sham control groups, the trial could potentially serve as one of the two pivotal trials typically required for marketing approval.
A properly designed Phase 2b screening trial has a considerable likelihood of ruling out ineffective or harmful interventions, while providing encouraging (or even statistically significant) evidence of benefit that likely would require confirmation by one additional, independent Phase 3 trial.
For the primary and secondary efficacy analyses we evaluated the ITT population in accordance with a prespecified statistical analysis plan.
The statistical evidence from the GATHER1 trial regarding the comparison of Zimura 2 mg to sham control is provided by data from both Part 1, with a 1:1 randomization ratio of patients receiving Zimura 2 mg (25 patients) and sham (26 patients), as well as data from Part 2, with a 1:2 randomization ratio of patients receiving Zimura 2 mg (42 patients) and sham (84 patients), for a total of 67 patients receiving Zimura 2 mg and 110 patients receiving sham. While we believe it is appropriate to use the aggregate data from Parts 1 and 2 in the analysis of the relative effects of Zimura 2 mg as compared to sham, it would not be appropriate to simply pool the data from patients in both Parts 1 and 2, in particular, because the randomization fraction differs across these two parts of the trial. However, based on the randomization procedures used in each part of the trial, for purposes of statistical comparisons, within Part 1 of the trial, the 25 patients receiving Zimura 2 mg should be comparable to the 26 patients receiving sham. Similarly, for purposes of statistical comparisons, within Part 2 of the trial, the 42 patients receiving Zimura 2 mg should be comparable to the 84 patients receiving sham. The efficacy of Zimura 2 mg was therefore evaluated through an analysis which included a regression factor by trial part. The statistical analysis for the Zimura 4 mg group as compared to sham compares data for patients from Part 2 of the trial only. Data from patients receiving Zimura 1 mg in Part 1 of the trial was not part of the prespecified statistical analysis for the efficacy endpoints.
The prespecified statistical analysis plan for the primary and secondary endpoints of this trial used the mixed-effects repeated measures model, or MRM, to compare data for the Zimura 2 mg and Zimura 4 mg groups to the corresponding sham groups. Repeated measures models are often used when the same outcome is measured at several time points for each patient. These models make use of all available data points to estimate the measurement of interest, the mean rate of change of GA growth, without making overly restrictive assumptions. In addition, these models are generally robust to missing data under the assumption that data are missing at random. During the course of a clinical trial, patients may withdraw from the clinical trial because their condition is asymptomatic, because patients believe that continued participation in the trial is not justified based on the time commitment or treatment burden, such as receiving monthly intravitreal injections, at the recommendation of the investigator or because the protocol requires it. Additionally, patients may not come to a scheduled visit at which key assessments are scheduled to be taken or patient data may not be evaluable because of poor image quality or data recording errors. Early withdrawal, missed visits and unevaluable data all result in data missing from the final data set for a clinical trial. Although the protocol called for collection of FAF images of GA at baseline, at month 6 and at month 12, for patients who withdrew from the trial before month 12, the study protocol required the collection of an FAF image to provide a measurement of GA at the time of withdrawal, which was included in the primary analysis so long as it was taken within the month prior to either the month 6 or month 12 time point. Because the MRM model would only need measurements from at least two different
18
time points for analysis purposes, one of which must be the baseline, we were able to include in the primary analysis all patients who had GA measurements at baseline and within the month prior to either month 6 or month 12, or both.
The following table sets forth for the data in the primary statistical analysis the number of patients for whom GA measurements were missing for purposes of performing this analysis. Patients whose GA measurements were missing at baseline, or at both month 6 and month 12, could not be included in the primary analysis. All other patients were included in the primary analysis.

In total, 53 (18.5%) patients withdrew from the trial during the first 12 months. Of the patients who withdrew during the first 12 months, 2 patients were from the Zimura 1 mg group (7.7% withdrawals), 12 patients were from the combined Zimura 2 mg group (17.9% withdrawals), 25 patients were from the Zimura 4 mg group (30.1% withdrawals) and 14 patients were from the combined sham group (12.7% withdrawals). GA measurements for patients who withdrew from the study prior to the 12 month time point may have been included in the MRM analysis, as detailed in the table above.
Sensitivity analyses. We performed several sensitivity analyses to assess the impact of missing data on the robustness of the GATHER1 trial results. The analyses we performed were based on approaches that the FDA generally recommends sponsors of investigational products use to evaluate their clinical data. Based on these analyses, and accounting for the data missing from our data set because of patient withdrawals or for other reasons, the statistical analysis for the 12 month data from the GATHER1 trial appear to be robust. Descriptions of these sensitivity analyses and their outcomes are summarized below. For a description of the thresholds we used to determine statistical significance on the primary efficacy endpoint, see the paragraph below the tables below under "Primary Efficacy Endpoint Data."
•A "shift imputation" approach, in which missing data are imputed, or replaced, by values calculated from similar patients with observed values, plus a defined shift. The analysis is repeated assuming a progressively larger shift with each iteration. The analysis becomes increasingly conservative as the shift increases (because missing values are replaced by worse values than would have been observed, had the values not been missing). The shift is increased until a tipping point is reached and statistical significance is lost. If significance is lost for smaller shift values, the results of the analyses are sensitive to missing data, whereas if significance is lost for larger shift values, the results of the analyses are robust to missing data.
A shift of at least 0.05 mm in terms of square root of GA growth was required to lose statistical significance for both the Zimura 2 mg and Zimura 4 mg groups. The difference between the Zimura treatment groups and the corresponding sham groups, in terms of mean change of square root of GA growth, was 0.11 mm for the Zimura 2 mg group and 0.12 mm for the Zimura 4 mg group, so a shift of 0.05 mm represents more than 40% of the observed treatment effect, which is large.
•Arbitrary imputation approaches, in which missing data are replaced by:
◦the mean value of the same treatment group, which seems a reasonable imputation approach since it replaces missing values by the mean of all observed values in the same treatment group;
◦the mean value of the comparator treatment group, which is a very conservative approach. If there is a treatment effect, missing values in the sham control group are replaced by better values, on average, from the Zimura treatment group, while missing values in the Zimura treatment group are replaced by worse values, on average, from the sham control group;
19
◦the mean value of both treatment groups, which is a conservative approach because it assumes no treatment effect for missing values; and
◦the mean value of the sham control group, which is also a conservative approach because it draws only upon data from the sham control group, which by definition did not have any treatment benefit.
Statistical significance for the reduction in mean rate of GA growth for the Zimura 2 mg and Zimura 4 mg groups as compared to the corresponding sham groups was retained for all arbitrary imputation approaches.
•A “pattern mixture model imputation” approach, which is a technically complex model and is especially useful when data are suspected to be missing “not at random”.
Statistical significance for the reduction in mean rate of GA growth for the Zimura 2 mg and Zimura 4 mg groups as compared to the corresponding sham groups was retained for the pattern mixture model imputation approach, which suggests again that the results of the analyses are robust to missing data, even if these data had been missing not at random.
Based on our sensitivity analyses, and accounting for the data missing from our data set because of patient withdrawals or for other reasons, we believe the statistical analysis for the 12 month data from the GATHER1 trial is robust.
Primary Efficacy Endpoint Data
The prespecified primary efficacy endpoint was an anatomic endpoint, the mean change in rate of GA growth over 12 months, as measured by FAF based on readings at three time points: baseline, month 6 and month 12, calculated using the square root transformation of the GA area. The readings were performed by an independent masked reading center. The primary efficacy endpoint data are summarized in the following table:

The analysis of the mean change in GA growth for Zimura 2 mg as compared to Sham 2 mg was adjusted for the fact that this dose of Zimura was tested in the two parts of the trial, which had different randomization ratios. The least squares mean changes in GA in Part 1 and Part 2 are shown separately in the following table:

When the data from the Zimura 2 mg comparisons from each Part of the trial are analyzed using the MRM model, which includes a regression factor by part, the mean difference in GA growth over 12 months between the Zimura 2 mg and sham control groups is 0.110 mm.
Statistical significance is established by performing statistical analysis on a data set to assess the degree to which an observed outcome is likely to be associated with variability in the studied patient population or chance as compared to the impact of the investigational product being studied. A higher degree of statistical significance is associated with a lower p-value. Typically, a two-sided p-value of 0.05 or less represents statistical significance when performing only a single prespecified primary analysis for a single primary endpoint. However, when multiple doses of a drug are tested, a more stringent statistical method that accounts for multiple comparisons must be applied. For this purpose, we used the Hochberg multiple comparison procedure to assess the statistical significance of the results observed in the GATHER1 trial. Under the Hochberg procedure, it is necessary to use a stricter standard for statistical significance (a two-sided p-value of 0.025 or less) for any particular dose. For GATHER1, the results for the primary efficacy endpoint observed for both the Zimura 2 mg and Zimura 4 mg groups, as compared to the corresponding sham group, achieved p-values of 0.0072 and 0.0051, respectively, both of which are less than 0.025, indicating that both results were statistically significant.
Observed GA Data (non-square root transformation)
In addition to analyzing the mean rate of change in GA area at month 12 using the square root transformation of the GA area (measured in millimeters (mm)), we also analyzed the mean rate of change in GA area using the observed GA area (without the square root transformation, measured in square millimeters (mm2)), with the MRM model. This descriptive analysis was also part of the prespecified statistical analysis plan for this trial. The observed mean GA area data for the Zimura 2 mg and Zimura 4 mg groups as compared to the corresponding sham control groups are summarized in the following table:

Secondary Efficacy Endpoints Data
The prespecified secondary endpoints in this trial were the mean change in BCVA from baseline to month 12 and the mean change in LL BCVA from baseline to month 12, both as measured by ETDRS letters. Testing for visual acuity serves as an important safety assessment to assure that the decrease in visual acuity in the Zimura treatment groups was not different
21
from the sham control groups. Because we believe that BCVA is not the optimal assessment to evaluate the impact of GA on patients’ functional vision, we included vision in the prespecified statistical analysis as a secondary, and not as a primary, endpoint.
The GATHER1 trial was not designed to reliably assess differences in mean changes in BCVA or LL BCVA with statistical significance. Data for the secondary endpoints are summarized in the following tables:

Zimura 1 mg 12-Month Efficacy Data
Efficacy data from patients receiving Zimura 1 mg was not part of the prespecified statistical analysis. The total number of patients randomized to the Zimura 1 mg group (26 patients) is relatively small, and the trial was not powered to reliably assess differences in outcomes for these patients as compared to patients in the sham control group in Part 1 (26 patients). However, we performed descriptive analyses on the 12 month data for patients in the Zimura 1 mg as compared to the patients in the sham control group in Part 1 of the trial to aid our assessment of whether a dose response relationship was present across treatment groups included in the clinical trial.
GA area data for the Zimura 1 mg group and the sham group from Part 1 of the trial are summarized in the following tables:

Although the sample size for the Zimura 1 mg group is small, we believe the apparent reduction in mean percentage change in GA area from baseline to month 12 in the Zimura 1 mg group as compared to the sham control group in Part 1, when
22
combined with the statistically significant results observed for the primary efficacy endpoint for the Zimura 2 mg and Zimura 4 mg groups as compared to their corresponding sham control groups, suggest a potential dose response relationship across treatment groups.
18-Month Data
The primary purpose of the 18 month time point was to gather additional safety data. This trial was not designed to assess, and the prespecified statistical analysis plan for the trial did not include assessing, the statistical significance of the 18 month efficacy data for the treatment groups as compared to the corresponding sham control groups. The reduction in the mean rate of GA growth over 18 months was 28.11% for the Zimura 2 mg group as compared to the corresponding sham control group and 29.97% for the Zimura 4 mg group as compared to the corresponding sham control group. The descriptive p-values for the treatment effects at month 18 were p=0.0014 for the Zimura 2 mg group and p=0.0021 for the Zimura 4 mg group. The analysis of the 18-month efficacy data is descriptive only.
GA Growth Data over 18 Months
The mean rate of change in GA growth over 18 months was measured by FAF based on readings at four time points (baseline, month 6, month 12 and month 18) and was calculated using the square root transformation of the GA area. The FAF images were assessed by an independent masked reading center. The prespecified statistical analysis plan used MRM to compare data for the Zimura 2 mg and Zimura 4 mg groups to the corresponding sham groups. Detailed data are shown below (the p-values for the 18 month statistical analyses are descriptive in nature):

18-Month Zimura 2 mg GA Data by Part
Consistent with the analysis performed at 12 months, the analysis of the mean change in GA growth for Zimura 2 mg as compared to the corresponding sham control group over 18 months was adjusted for the fact that this dose of Zimura was tested in both Part 1 and Part 2 of the trial, each of which had different randomization ratios.
The least squares mean changes in GA in Part 1 and Part 2 at month 18 are shown separately in the following table:

Observed 18-Month GA Data (non-square root transformation)
In addition to analyzing the mean rate of change in GA area at month 18 using the square root transformation of the GA area (measured in millimeters (mm)), we also analyzed the mean rate of change in GA area using the observed GA area (without the square root transformation, measured in square millimeters (mm2)), with the MRM model.

18-Month Visual Acuity Data
In addition to analyzing mean change in GA area, we also performed pre-specified analyses of the mean change in BCVA from baseline to month 18 and the mean change in LL BCVA from baseline to month 18, both as measured by ETDRS letters. Testing for visual acuity serves as an important safety assessment to assure that the decrease in visual acuity in the Zimura treatment groups was not clinically different from the sham control groups.
The GATHER1 trial was not designed to reliably assess differences in mean changes in BCVA or LL BCVA with statistical significance. Data for the mean change in BCVA and LL BCVA at month 18 are summarized in the following tables:

Zimura 1 mg 18-Month Efficacy Data
We performed descriptive analyses on the 18 month data for patients in the Zimura 1 mg group as compared to the patients in the sham control group in Part 1 of the trial.
The mean rate of change in GA area for the Zimura 1 mg group and the corresponding sham group from Part 1 of the trial over 18 months is summarized in the following table:

Although the sample size for the Zimura 1 mg group is small, we believe the apparent reduction in mean percentage change in GA area from baseline to month 18 in the Zimura 1 mg group as compared to the sham control group, when compared with the results observed in the Zimura 2 mg and Zimura 4 mg groups as compared to their corresponding sham control groups, may suggest a potential dose response relationship across treatment groups.
18-Month Safety Data
Based on our review of the safety data in the trial, Zimura was generally well tolerated after 18 months of administration. During the trial, there were no investigator-reported Zimura-related adverse events, no Zimura-related intraocular inflammation, no Zimura-related increased intraocular pressure, no cases of endophthalmitis, and no discontinuations attributed by investigators to Zimura in the trial. Through month 18, the reported incidence of CNV in the untreated fellow eye was 11 patients (3.8%), and in the study eye was 3 patients (2.7%) in the sham control group, 2 patients (7.7%) in the Zimura 1 mg group, 8 patients (11.9%) in the Zimura 2 mg group, and 13 patients (15.7%) in the Zimura 4 mg group. The most frequently reported ocular adverse events were related to the injection procedure. The numbers below are based on investigator-reported adverse events occurring during the 18-month duration of the trial for all patients.

In addition to us collecting investigator-reported adverse events, the independent masked reading center performed multi-modal imaging analysis. Multi-modal imaging analysis is a process used to assess patient retinal findings by reviewing different image types, in this case optical coherence tomography, or OCT, images and fluorescein angiography, to provide a more comprehensive view of the patient's retinal tissue. OCT is an ultra-high resolution imaging technology commonly used to visualize the retinal tissue. OCT is capable of rendering images in multiple dimensions and from multiple perspectives, and is an imaging technique commonly used by retinal specialists to diagnose, treat and follow patients with CNV. Fluorescein angiography is a technique that involves injection of a fluorescent dye into the systemic circulation and capturing images showing the circulating dye during transit through the retinal circulation using a specialized camera. In this trial, the reading center's multi-modal imaging analysis identified one additional case of macular CNV for a patient in the Zimura 4 mg group at month 12. Because this patient's investigator did not detect the CNV, the patient remained in the trial through month 18.
Requirements for Regulatory Approval of Zimura in GA
To obtain regulatory approval for Zimura for the treatment of GA secondary to AMD, we expect that we will need to obtain favorable results from a total of two independent, adequate and well-controlled pivotal clinical trials, demonstrating the safety and efficacy of Zimura in this indication. To establish efficacy, we believe it would be sufficient to demonstrate robust, statistically significant results showing a clinically relevant reduction in the rate of growth of GA over 12 months, based on measurements over three time points (baseline, month 6 and month 12) in two independent trials. We selected this measure as the primary endpoint for the GATHER1 trial based on prior formal interactions with the FDA, as well as our understanding of clinical trials for other investigational products in development for the treatment of GA. We designed the GATHER1 trial as a well-controlled screening trial such that, in the event that the prespecified primary efficacy endpoint results were statistically significant, the trial could potentially serve as one of the two pivotal clinical trials typically required for marketing approval. Based on the results we have received, the statistical analysis that we have performed and informal discussions we have had with the FDA, we believe that the safety and efficacy results from the GATHER1 trial could potentially satisfy the FDA’s requirements as one of the two pivotal clinical trials typically required for marketing approval. In the paragraphs that follow, we describe in detail the basis for our belief.
Requirements for Safety Data
Zimura has generally been well tolerated in our clinical trials to date. In the GATHER1 trial, there were no investigator reported ocular serious adverse events, Zimura-related adverse events, cases of Zimura-related intraocular inflammation, cases of Zimura-related increased intraocular pressure, cases of endophthalmitis, or discontinuations attributed by investigators to Zimura. We believe the investigator reported CNV rate in the study eye for patients receiving Zimura as compared to sham and the untreated fellow eyes during the trial is within an acceptable range when compared to published clinical trial data for another complement inhibitor currently in development for GA. The most frequently reported ocular adverse events in the GATHER1 trial were related to the injection procedure.
To demonstrate the safety of Zimura to a degree sufficient to support marketing approval, we believe that the FDA and EMA would require data from a minimum of 300 patients having received the dose of Zimura for which we are seeking approval, or a higher Zimura dose, independent of indication, for a minimum of 12 months, with 24-month safety data available for some portion, but not all, of these 300 patients. Including patients randomized to the Zimura 4 mg group in the STAR trial of Zimura for STDG1, we believe that we currently have 12-month safety data for approximately 140 patients who have received either monthly Zimura 2 mg or Zimura 4 mg for 12 months or more. Based on the safety profile of Zimura observed to date in these patients and the number of patients treated, we believe that the remaining minimum safety requirements could potentially be satisfied through a single additional, pivotal clinical trial providing for monthly administrations of Zimura 2 mg over 12 months, at which point the primary efficacy analysis would be performed, with treatment extending to 24 months for the overall safety analysis, with the potential for less frequent dosing after month 12.
Requirements for Efficacy Data
As described above, we believe that reduction in the rate of GA growth over 12 months, based on measurements over three time points (baseline, month 6 and month 12) is an efficacy endpoint that the FDA and EMA would likely accept in considering Zimura for approval for the treatment of GA secondary to AMD. The measurements for this endpoint are performed by a masked independent reading center to minimize the potential for bias.
Statistical Significance. In our GATHER1 trial, the reduction in the mean rate of GA growth over 12 months using the square root transformation was 0.110 mm (p-value = 0.0072) for the Zimura 2 mg group as compared to the corresponding sham control group and 0.124 mm (p-value = 0.0051) for the Zimura 4 mg group as compared to the corresponding sham control group, corresponding to an approximate 27% relative reduction in the mean rate of GA growth over 12 months when compared with sham. These data for both dose groups were statistically significant. See above under “Primary Efficacy Endpoint Data” for a discussion of the procedures we used to confirm the statistical significance of these data.
28
Clinical Relevance. Clinical relevance refers to an assessment of how meaningful the observed outcome is or would be for patients. The FDA and other regulatory authorities consult with clinicians in the field of study to advise on the relevance of an observed outcome for patients. Although there are no FDA or EMA approved therapies for the treatment of GA secondary to AMD, we understand that based on recent FDA guidance on human gene therapy products for retinal disorders, the FDA considers best curve fit analyses, such as an MRM model, that demonstrates a statistically significant reduction in the rate of photoreceptor loss, as determined based on FAF images, in a manner that includes measurements at baseline, month 6 and month 12, to be clinically meaningful. Our MRM uses a straight line analysis, which we believe satisfies the FDA's requirement for a best curve fit analysis. We also believe that our anatomic endpoint, reduction in the mean rate of GA growth, is an endpoint that the FDA would consider as a clinically relevant indicator of a reduced rate of photoreceptor loss. Since established literature and clinical experience indicates that patients' functional vision is impacted by the growth of the GA over time, which ultimately leads to severe vision loss, we believe that reduction of GA growth would have a meaningful impact on the patients’ well-being and quality of life and therefore is clinically relevant.
Robustness. In addition to statistical significance and clinical relevance, data from pivotal clinical trials must be robust. The International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use defines robustness as a concept that refers to the sensitivity of the overall conclusions to various limitations of the data, assumptions, and analytic approaches to data analysis. GATHER1 is an international, randomized, double-masked, sham controlled, multi-center clinical trial. The primary endpoint, the statistical analysis of which was prespecified, is an objective anatomic endpoint based on measurements performed by a masked independent reading center. The images are analyzed by two experienced image readers, with any discrepancy of greater than 10% arbitrated by the reading center director, who is a recognized expert in the field of GA. The patients, investigators, independent reading center and we as the sponsor each remain masked throughout the duration of the entire trial, which in the case of the GATHER1 trial, means each of us remained masked until after the 18-month time-point.
In clinical trials, it is common for data for some number of subjects to be missing for assessments performed throughout the trial. The degree of data that is missing from a clinical data set can impact the robustness of the data. See above under “Statistical Analysis for Efficacy Measures” for information regarding the GA measurement data that was missing from the analysis of the primary efficacy endpoint in the GATHER1 trial, as well as a description of the sensitivity analyses we have performed. Based on our sensitivity analyses, and accounting for the data missing from our data set because of patient withdrawals or for other reasons, we believe the statistical analysis for the 12 month data from the GATHER1 trial is robust.
Although we seek to apply our enrollment criteria consistently, there may be instances where an investigator proposes a patient to participate in the trial and the reading center determines that, although a patient may not meet all criteria precisely, participation in the trial is warranted based on the overall GA pattern and size. For example, this can result in the enrollment of patients with baseline GA area slightly below 1 disc area, as was the case with one patient in each of the Zimura 4 mg group and the Part 2 sham control group (which is part of the comparison for both the Zimura 2 mg and Zimura 4 mg groups). These patients have been included in the ITT analysis for our primary efficacy endpoint. The FDA, EMA or other regulatory authorities may not agree with the inclusion of these patients in our statistical analysis, which could impact the robustness of our conclusions.
Our Regulatory Pathway Following GATHER1
Based on the foregoing, assuming that Zimura’s safety profile remains consistent with findings observed to date and subject to regulatory review of the robustness of the GATHER1 trial results, we believe that one additional international, randomized, double-masked, sham controlled, Phase 3 clinical trial is needed to demonstrate the safety and efficacy of Zimura in GA secondary to AMD in a manner sufficient to support an application for regulatory approval from the FDA and EMA in this indication. We designed the GATHER2 trial in accordance with this belief and understanding. Our belief and understanding of the remaining clinical requirements to demonstrate the safety and efficacy of Zimura for the treatment of GA secondary to AMD in a manner sufficient to support an application for regulatory approval from the FDA and EMA is based on our review of the data from the GATHER1 trial as well as informal discussions with the FDA. We have not had a formal interaction with the FDA or any interactions with the EMA regarding the GATHER1 data. It is possible that unexpected or inconsistent findings could emerge as we continue to evaluate the unmasked, individual patient data, which could cause us to evaluate and change our conclusions about this data. Our expectations regarding the minimum clinical requirements to demonstrate the safety and efficacy of Zimura for GA may change as new regulatory or third party information becomes available. Ultimately, for the GATHER1 trial to be accepted as a pivotal trial, the FDA, EMA and other regulatory authorities would need to agree that the overall data package from the GATHER1 trial and a subsequent pivotal clinical trial, such as GATHER2, meet the applicable requirements and are sufficiently robust to demonstrate an acceptable safety profile, together with a clinically relevant efficacy outcome with statistical significance, and that the data support an overall favorable benefit-to-risk determination.

GATHER2: Ongoing Phase 3 Clinical Trial Assessing Safety and Efficacy of Zimura 2 mg for GA Secondary to AMD
In this trial, we plan to enroll approximately 400 patients, who will be randomized into two groups: a first group receiving monthly administrations of Zimura 2 mg for 12 months, and a second group receiving monthly administrations of sham. The prespecified primary endpoint will be the mean rate of change in GA growth over 12 months, as measured by FAF based on readings at three time points: baseline, month 6 and month 12, calculated using the square root transformation of the GA area, which is the same primary efficacy endpoint we used for the GATHER1 trial. At month 12, we plan to re-randomize patients in the Zimura 2 mg arm to receive either monthly or every other month administrations of Zimura 2 mg, and all patients receiving monthly administrations of sham will continue to receive monthly administrations of sham. We plan to treat and follow all patients for 24 months.
The key ophthalmic inclusion criteria for GATHER2 include the following:
•non-foveal GA secondary to dry AMD;
•total GA area between 2.5 mm2 and 17.5 mm2, inclusive;
•if GA is multifocal, at least one focal lesion should measure 1.25 mm2 or greater;
•GA in part within 1500 microns from the foveal center; and
•Snellen equivalent BVCA in the study eye between 20/25 and 20/320, inclusive.
As discussed above, when we initiated the GATHER1 trial, we did not believe that reliable measurements of GA by FAF images for patients with CNV in the study eye could be performed. Therefore, in the clinical trial protocol for the GATHER1 trial, we indicated that patients in any arm of the trial who developed CNV in the study eye, as observed by the investigator, would be removed from the trial and any future study treatments and assessments. Based on third-party clinical data published since the GATHER1 trial commenced and discussions with our independent reading center, we believe that GA for patients developing CNV in the study eye who receive standard of care anti-VEGF treatment for the CNV, could potentially be assessed by FAF. Based on the foregoing, the protocol for GATHER2 provides that patients will undergo monthly OCT imaging, and if an investigator suspects that a patient has CNV or if a patient experiences a decrease in visual acuity, as measured by a loss of more than five ETDRS letters between a visit and the immediately prior visit, the independent masked reading center will confirm whether the patient has CNV using multi-modal imaging. In the event a CNV case is confirmed, the investigator will treat the CNV with one of two anti-VEGF agents, Lucentis or Eylea® (aflibercept), in accordance with the label for that anti-VEGF agent. These patients will remain in the trial and measurements of these patients' GA will be included in the primary efficacy analysis if their FAF images can be assessed by the masked reading center.
In June 2020, we dosed the first patient in GATHER2. We are continuing to recruit and enroll patients in this trial and expect to complete patient enrollment during the third quarter of 2021. Meanwhile, we continue to monitor the COVID-19 pandemic closely and may need to slow down or stop patient enrollment in certain geographies depending on the local situation. We have added sites to this trial due to the ongoing and variable nature of the COVID-19 pandemic and its potential impact on patient recruitment and retention.
OPH2001: Completed Phase 1/2a Clinical Trial of Zimura for GA Secondary to Dry AMD
In 2011, we completed a multicenter, uncontrolled, open label Phase 1/2a clinical trial to evaluate the safety and tolerability of Zimura administered as a monotherapy in patients with GA. We enrolled 47 patients in this trial. We randomly assigned patients in this trial to one of two dose groups. Patients received a total of five intravitreal injections of either 0.3 mg or 1 mg of Zimura over a 36-week treatment period. Patients received an intravitreal injection of Zimura at day 0, week 4, week 8, week 24 and week 36 of the trial, with a final follow-up visit at week 48.
Zimura was generally well-tolerated in this trial. We did not observe any evidence of drug related adverse events. We also did not observe any incidence of conversion to wet AMD in eyes treated with Zimura. Adverse events were primarily ocular adverse events in the study eye which were related to the injection procedure.
In addition, we performed assessments of visual acuity to detect any potential decrease in vision associated with intravitreal injections, the administered drug or natural progression of the disease if left untreated. We did not identify any drug related safety issues through measurements of visual acuity.
Our Phase 1/2a clinical trial was an uncontrolled study with a small sample size and was not powered to detect a difference between Zimura dose groups, or the efficacy of Zimura monotherapy, with statistical significance. The primary
30
purpose of the study was to assess safety and tolerability. However, during the more frequent dosing period, which is the first 24 weeks, we observed a trend, in favor of the higher of two dose groups, of a relative reduction in the mean growth of the GA lesion area, as measured by fundus autofluorescence images read by an independent reading center.
The mean growth from baseline in the GA lesion area during the first 24 weeks of the trial, when the injections were administered more regularly, was 1.00 mm2 for the 24 patients receiving the 0.3 mg dose and 0.78 mm2 for the 23 patients receiving the 1 mg dose. When the injections were administered on a reduced dosing schedule during the subsequent 24 weeks, this relative trend in reduced growth in GA lesion area was no longer present.
The following graph sets forth the mean change in GA lesion area from baseline for the two treatment groups over the course of the trial.
We believe this apparent trend in the relative reduction of mean growth in GA lesion area when Zimura was dosed more frequently, together with the relative loss of the benefit when Zimura was dosed less frequently, may suggest a possible drug effect.
Zimura - STGD1 Trials
STAR: Ongoing Phase 2b Clinical Trial of Zimura for STGD1
We initially completed patient enrollment for this clinical trial in February 2019 with a total of 95 patients enrolled, all of whom have completed their scheduled visits as of September 2020. In July 2020, we reopened enrollment in this trial in the United States. We plan to enroll approximately 25 additional patients, with the goal of enrolling a total of approximately 120 patients. Similar to GATHER2, we continue to monitor the COVID-19 pandemic closely and may need to slow down or stop patient enrollment in certain geographies depending on the local situation.
All initially enrolled patients were, and any newly enrolled patients are, randomized in a 1:1 ratio as follows:
•Zimura 2 mg, followed by Zimura 2mg 14 days later, monthly for three months during an induction phase; followed by Zimura 4 mg, administered as two injections of Zimura 2 mg on the same day, monthly for 15 additional months during a maintenance phase; and
•a sham injection, followed by a sham injection 14 days later, monthly for three months; followed by two sham injections on the same day, monthly for 15 months.
We plan to evaluate the primary efficacy endpoint in this trial at 18 months. The primary efficacy endpoint is an anatomic endpoint, the mean rate of change in the area of ellipsoid zone defect, as measured by en-face OCT. OCT allows the demonstration of various layers of the retinal tissue, including the ellipsoid zone, which is a part of the photoreceptor cells. Scientific literature correlates defects in the ellipsoid zone with the loss of visual acuity and visual dysfunction. The ellipsoid
31
zone is rendered in OCT images as a defined layer of photoreceptor cell segments. Areas of defects in the ellipsoid zone can be detected and measured by en-face OCT, which shows an OCT image from the perspective of looking at the retina head-on.
We have not previously studied Zimura in STGD1 patients and thus do not have any clinical data regarding the effect of Zimura in STGD1. We previously engaged the Foundation Fighting Blindness to provide us with data from the Foundation's publicly available ProgStar study, the largest natural history study on Stargardt disease to date. We have used this natural history data, as well as the perspectives of the key opinion leaders involved in the ProgStar study, as resources to assist in the design of the STAR trial. As STGD1 is an orphan indication, to our knowledge there is only very limited natural history data currently available regarding the variability of the planned primary efficacy endpoint in the STGD1 patient population we enrolled in this trial. Given the information above, this trial could be underpowered to demonstrate a potential clinical benefit for Zimura in this indication.
Similar to GATHER1, STAR is designed to be a Phase 2b screening trial, with the potential to demonstrate statistically significant results depending on the magnitude of the potential benefit observed. If the results are positive and statistically significant, we believe this trial could potentially serve as a clinical trial that can support an application for marketing approval. However, we have not yet engaged with the FDA or the EMA about this belief and expectation.
Even though we have reopened patient enrollment, we have been and plan to remain masked to the treatment condition of all patients in the trial. In addition, we have not reviewed and do not plan to review or analyze efficacy data for any patients in the trial, until the 18-month data has been collected and analyzed for all patients enrolled in the trial.
Zimura - Wet AMD Trials
OPH2000: Completed Phase 1/2a Clinical Trial of Zimura for Wet AMD
In 2009, we completed a multicenter, uncontrolled, ascending dose and parallel group, open-label, first in human Phase 1/2a clinical trial to evaluate the safety and tolerability of multiple intravitreal injections of Zimura given in combination with multiple doses of Lucentis 0.5 mg in patients with wet AMD. We enrolled 60 patients in this trial, of which 58 were treatment-naïve patients, and two were treatment-experienced patients.
Patients were treated at one of five Zimura dose levels: 0.03 mg, 0.3 mg, 1 mg, 2 mg and 3 mg. Zimura was generally well tolerated in this trial when tested in combination with Lucentis. None of the patients experienced any dose limiting toxicities at any of the dose levels tested. We observed only a single adverse event assessed by the investigators to be related to Zimura, mild subcapsular cataract in one patient in the group treated with Zimura 2 mg. Despite this event, this patient's visual acuity improved during the study. Adverse events were primarily ocular adverse events in the study eye which were related to the injection procedure. One patient from the 0.3 mg Zimura treatment group withdrew from the trial as a result of a serious adverse event of bacteremia unrelated to study drug or injection procedure, which resulted in a subsequent fatality. Another patient from the 0.3 mg treatment group withdrew from the trial due to the investigator's decision. Systemic adverse events in this trial were not frequently reported. No systemic adverse events were assessed as drug related.
Our Phase 1/2a clinical trial was an uncontrolled study with a small sample size and was not powered to detect a difference between Zimura dose groups or the efficacy of Zimura combination therapy with statistical significance. The primary purpose of the study was to assess safety and tolerability. In addition to our safety assessment, however, we also performed assessments of visual acuity. There was a general trend towards an improvement in visual acuity seen in all treatment groups. We focused our assessment of vision outcomes on the subgroup of 43 treatment-naïve patients who had received all six Zimura injections at the same dosage. We observed a mean increase in visual acuity from baseline at all time points for these patients, based on the number of ETDRS letters the patient could read. For this subgroup, at week 24 of the trial, we noted improvements in mean visual acuity from baseline as follows: 13.6 letters for the 13 patients receiving the 0.3 mg dose, 11.7 letters for the 15 patients receiving the 1 mg dose and 15.3 letters for the 15 patients receiving the 2 mg dose. In this subgroup, 22 patients (51%) gained at least 15 ETDRS letters, defined as significant visual gain, consisting of six patients (46%) in the 0.3 mg dose group, seven patients (47%) in the 1 mg dose group and nine patients (60%) in the 2 mg dose group.
OPH2004: Discontinued Phase 2a Trial of Zimura for Treatment-Experienced Wet AMD Patients
During the fourth quarter of 2015, we initiated an open-label Phase 2a clinical trial to evaluate Zimura’s potential role when administered in combination with anti-VEGF therapy for the treatment of wet AMD in anti-VEGF treatment-experienced patients who did not respond adequately to anti-VEGF monotherapy. In 2017, following our reassessment of our Zimura development programs, we stopped enrolling patients in this trial as we determined that we would initiate a new Zimura wet AMD trial, the OPH2007 trial described below, for treatment-naïve patients. One patient continued to receive treatment in this
32
trial until the first half of 2018. This patient did not experience any drug-related adverse events and there were no unexpected safety issues.
OPH2007: Completed Phase 2a Clinical Trial of Zimura for Treatment-Naïve Wet AMD Patients
In 2018, we completed a randomized, dose-ranging, open-label, multi-center Phase 2a clinical trial of Zimura in combination with Lucentis 0.5 mg to evaluate the safety of different dosing regimens of Zimura in combination with an anti-VEGF agent in treating wet AMD. We enrolled and treated a total of 64 treatment-naïve patients for this trial. We assigned patients in this trial to one of four groups:
•In Groups 1 and 2, consisting of ten patients in each group, patients received monthly combination therapy consisting of Lucentis 0.5 mg followed by, in Group 1, Zimura 4 mg two days later and in Group 2, Zimura 2 mg on the same day as the Lucentis treatment;
•In Groups 3 and 4, consisting of 22 patients in each group, patients received dosages in two phases, consisting of:
◦first, an induction phase from day one to the second month, during which the patients received Lucentis 0.5 mg followed by Zimura 2 mg on the same day, followed by Zimura 2 mg fourteen days later; and
◦second, a maintenance phase from the third month to the fifth month, during which the patients received, in Group 3, Lucentis 0.5 mg followed by Zimura 2 mg on the same day and in Group 4, Zimura 2 mg followed two days later with Lucentis 0.5 mg and Zimura 2 mg.
From a safety perspective, Zimura combination therapy with Lucentis was generally well tolerated after six months of treatment. The most frequently reported ocular adverse events were related to the injection procedure. We did not observe any adverse events attributable to Zimura combination therapy.
Our Phase 2a clinical trial was an uncontrolled trial with a small sample size designed to assess safety at different dosages and to detect a potential efficacy signal. This trial was not designed to detect a statistically significant difference between Zimura dose groups or to evaluate the efficacy of Zimura combination therapy with statistical significance.
We evaluated the mean change in BCVA at the six-month timepoint as compared to baseline. The data are summarized as follows:
•In Group 1, the mean change in visual acuity was 9.0 ETDRS letters with a median of 7.0 letters, and 40% of the patients gained greater than or equal to three lines of vision, or 15 ETDRS letters, defined as significant visual gain;
•In Group 2, the mean change in visual acuity was 10.2 ETDRS letters with a median of 16.0 letters, and 60% of patients gained greater than or equal to 15 ETDRS letters;
•In Group 3, the mean change in visual acuity was 10.7 ETDRS letters with a median of 10.0 letters, and 40.9% of patients gained greater than or equal to 15 ETDRS letters; and
•In Group 4, the mean change in visual acuity was 9.9 ETDRS letters with a median of 11.0 letters, and 18.2% of patients gained greater than or equal to 15 ETDRS letters.
Zimura - IPCV Trials
OPH2002: Completed Phase 2a Clinical Trial of Zimura for IPCV
In late 2014, we initiated a very small, uncontrolled, open-label, Phase 2a clinical trial to evaluate Zimura’s potential role when administered in combination with anti-VEGF agents for the treatment of IPCV in treatment-experienced patients for whom anti-VEGF monotherapy failed. IPCV is an age-related disease that is similar to wet AMD and is commonly characterized by leakage under the RPE, subretinal hemorrhage and RPE detachment. We enrolled four patients in the trial. None of the patients had a greater than 15-ETDRS letter decrease in visual acuity, which is considered a significant loss in visual acuity, following treatment in this study. None of the patients experienced any drug-related adverse events and there were no unexpected safety issues from this trial.
33
OPH2006: Discontinued Phase 2a Trial of Zimura for IPCV
In late 2017, we initiated a randomized, dose-ranging, open-label Phase 2a clinical trial of Zimura in combination with Eylea in treatment-experienced patients with IPCV. We did not enroll any patients in this clinical trial and decided to discontinue this clinical trial.
IC-500: HtrA1 Inhibitor Product Candidate
In October 2018, we acquired from funds controlled by Versant Ventures a number of HtrA1 inhibitors. In previous experiments conducted before the acquisition, these HtrA1 inhibitors showed high affinity and specificity for HtrA1 when tested in vitro. In 2020, we selected the lead compound from this group of HtrA1 inhibitors, which we call IC-500, for preclinical development. We are currently developing IC-500 for the treatment of GA secondary to AMD and evaluating HtrA1 inhibition as a potential treatment for other stages of AMD and potentially other age-related retinal diseases.
The HtrA1 gene encodes for an enzyme that may affect cellular structure, function and homeostasis, which is the dynamic equilibrium maintained in cells and tissue required for normal physiology. Genetic linkage studies, including a study published in Molecular Vision in 2017, show a correlation between the expression of HtrA1 and a certain set of genes conferring risk for AMD. A study of post-mortem eyes from subjects with AMD published in EBioMedicine in 2018 found overexpression of HtrA1 in RPE cells as compared to the eyes of non-AMD subjects. Additionally, the overexpression of HtrA1 was found, in an in vitro experiment published in the same article, to lead to alterations and disruptions in the morphology and function of RPE cells. Although the causal pathway between expression of HtrA1 and AMD is still not well understood, we believe that these findings suggest that HtrA1 overexpression may play a role in AMD and that molecules involved in the regulation and inhibition of HtrA1 may have therapeutic benefit in the treatment of GA secondary to AMD as well as other stages of AMD and potentially other age-related retinal diseases.
In early 2021, we completed a review of our IC-500 development program, which we had previously designed to support monthly dosing in our planned first-in-human clinical trial. We believe that we may be able to establish, at an earlier stage of development, a dosing regimen for IC-500 with less frequent dosing than we had previously planned. As a result, we have revised our development plans and timelines for IC-500 with the goal of including both monthly dosing and a less frequent dosing regimen in our first-in-human clinical trial. Currently, we are planning to initiate a number of preclinical pharmacokinetic, tolerability and target engagement studies for IC-500. We are also conducting additional formulation development activities and planning for cGMP manufacturing activities for IC-500. Based on current timelines and subject to successful preclinical development and cGMP manufacturing, we expect to file an IND for IC-500 during the second half of 2022.
Gene Therapy Research and Development Programs
Since 2017, as we evaluated our strategic priorities and the market for orphan and age-related retinal diseases with unmet medical needs, as well as the available technologies in development to potentially address these needs, we have been particularly encouraged by the prospects for gene therapy as a potential treatment option for retinal diseases. We have in-licensed two gene therapy product candidates and established collaborative gene therapy sponsored research programs with three leading academic research institutions in the United States. These sponsored research programs are focused on generating data to support the preclinical development of our gene therapy product candidates and discovering and developing other novel gene therapy technologies to treat a number of orphan IRDs.
The Potential of Gene Therapies for Retinal Diseases
Gene therapy consists of delivering DNA encoding for a functional protein to a target tissue to facilitate protein synthesis using a recipient's existing cellular machinery. Gene therapy can be used to replace a non-functional protein produced innately by the subject as a result of a genetic mutation or as a means of producing and delivering a therapeutic protein that would not otherwise be produced within the body. Many IRDs are monogenic, meaning they are caused by mutations in a single gene, and therefore could potentially be addressed by a gene replacement approach. For genetic diseases where the mutant protein has toxic effect, we have been encouraged by the potential for a “knockdown” and “replace” approach in which gene therapy not only can introduce a wildtype version of the gene into the host body but also can suppress the expression of the mutant gene. Furthermore, because gene therapy may result in a lasting, or even permanent, addition to a host body's genetic code, gene therapy has potential for an extended treatment effect through a single administration. We therefore believe that gene therapy also holds promise as a potential treatment for age-related and other non-orphan retinal diseases, especially for diseases where patients might otherwise require chronic therapy over years, if not decades.
34
Currently, most gene therapies for application in the eye are administered via subretinal injection. Subretinal injection is a surgical procedure in which the gene therapy vector is injected by a retinal surgeon into the potential space between the photoreceptors and the RPE and often as close as practicable to the site of desired protein expression. Once the vector is present in the target tissue area, the process by which the gene of interest is inserted into host cells by the delivery vehicle can begin. This process is referred to as transduction and the gene therapy delivery vehicle is referred to as a vector.
Gene Therapy Products and AAV Vectors
A gene therapy product typically includes the gene of interest, or transgene, together with a promoter sequence. The composition of the transgene may differ from that of the wildtype form of the gene—for example, the gene may be modified to increase the expression of the target protein. Promoters are DNA sequences that are linked to a gene and control the transcription of a gene into RNA in the host body's cells. There are cell-specific promoters, which tend to drive gene expression in particular cell or tissue types - for example, the RPE and photoreceptors. The choice of the specific promoter that is to be linked to a given transgene is an important consideration in constructing a gene therapy product.
The promoter-transgene combination is packaged together into a delivery vehicle to facilitate localization within the relevant tissue within the body. Gene therapies are typically delivered via viral vectors and among those, AAV has become the most common choice for gene therapy applications inside the eye. AAV is a small, non-pathogenic virus. To create the vector, the DNA encoding the AAV viral genes is removed, disarming the virus, and is replaced with the therapeutic gene sequence. In addition to AAV, other gene delivery vehicles include vectors derived from lentivirus and non-viral based vectors.
We are focused on AAV gene therapies, as AAV vectors have generally been found to transduce RPE, photoreceptors and other retinal cells at a high rate, and their safety profile in humans is relatively well-documented as compared to other delivery vehicles, such as lentiviral vectors. Gene editing approaches, such as CRISPR, in which the host DNA is modified, altered or removed via therapeutic intervention, are also emerging as a potential treatment options for genetic diseases. Unlike lentiviral vectors or gene editing approaches, with AAV gene therapy, the delivered genetic cargo does not incorporate into or alter the host cell's existing DNA and chromosomes, but rather remains separate in the host cell, where it can be transcribed by the host cell's existing machinery.
There are several naturally-occurring serotypes of AAV, including AAV2, AAV5, AAV8 and AAV9, as well as countless synthetic AAV serotypes. The AAV genome consists of two genetic sequences: a "Rep" gene that encodes for certain viral life-cycle proteins, and a "Cap" gene that encodes for proteins that form the viral capsid, which is the outer shell of the AAV. Recombinant AAV vectors can be created by combining the Rep sequence for one AAV serotype with the Cap sequence for another AAV serotype. For example, a recombinant AAV 2/5 vector is produced using the AAV2 Rep sequence and the AAV5 Cap sequence to package the transgene inside an AAV5 capsid. Because different capsid proteins have different transduction capabilities within different types of cells, the selection of the capsid serotype is an important consideration in constructing an AAV gene therapy product.
One of the primary limitations with AAV gene therapy is AAV's packaging capacity: an AAV vector can hold only up to approximately 4,700 base pairs of DNA, whereas the genes associated with a number of monogenic IRDs, such as the CEP290 gene associated with LCA10 and the ABCA4 gene associated with STGD1, exceed that size. A possible solution to the size limitation would be to develop a minigene form of transgene that would be small enough to fit within the packaging capacity of AAV, but large enough for the resulting protein to maintain its function. Another potential limitation for AAV and other viral vector gene therapies is the potential to trigger an immune response. Because many types of AAV are naturally occurring, gene therapy patients may have built up neutralizing antibodies to specific AAV serotypes prior to gene therapy administration, which may result in an inflammatory immune response and tissue damage. The safety profile of AAV, however, is well-documented, and furthermore, the relative isolation of the human eye and ocular immune system within the body may mitigate the potential immune response from the administration of AAV into the eye. Our current gene therapy programs, which are described in further detail below, use AAV vectors for delivery of the genetic cargo to cells within the retina.
IC-100: RHO-adRP Product Candidate
In June 2018, we entered into an exclusive global license agreement with UFRF and Penn for rights to develop and commercialize IC-100, our novel AAV gene therapy product candidate for the treatment of RHO-adRP. There are over 150 known mutations in the RHO gene that can result in RHO-adRP. In individuals with RHO-adRP, the rhodopsin that is produced by the mutant gene is toxic. The construct for our RHO-adRP product candidate combines in a single AAV2/5 vector:
35
•a transgene for a highly-efficient, novel short hairpin RNA, or shRNA, designed to target and "knockdown" expression of the subject's innate rhodopsin, regardless of the specific mutation a subject has, with
•a transgene for a healthy rhodopsin protein that is resistant to the shRNA.
Our RHO-adRP construct was tested by investigators at Penn in a naturally occurring canine model of RHO-adRP, resulting in long term, i.e., over 8 months, anatomic and functional preservation of the photoreceptors, which was demonstrated with histology and electrophysiology. The investigators had initially tested a dual vector construct in which the shRNA and the healthy RHO transgenes were delivered by different AAV vectors. The investigators found, however, that the dual vector approach caused inflammation and other complications in the retina, leading the investigators to develop this single vector construct. The results from these experiments were published by scientists at Penn and UF in PNAS in August 2018 in a paper titled: "Mutation-independent Rhodopsin Gene Therapy by Knockdown and Replacement with a Single AAV Vector."
In addition to the exclusive license agreement, we also entered into a master sponsored research agreement with Penn, facilitated by the Penn Center for Innovation, or PCI, in June 2018, pursuant to which we, together with Penn, conducted a number of additional preclinical studies of IC-100 and a natural history study of RHO-adRP patients.
We are working with a gene therapy CDMO for preclinical and Phase 1/2 clinical supply of IC-100. We are completing manufacturing activities for a cGMP batch of IC-100 produced by our CDMO. We completed toxicology studies of IC-100. We are planning for a Phase 1/2 clinical trial for IC-100, including site selection and other startup activities. We are planning to meet with the FDA to discuss our selected doses for a first-in-human clinical trial before we file an IND for IC-100. Based on current timelines and subject to feedback from the FDA, we plan to file an IND for IC-100 and subject to regulatory review, we expect to begin patient enrollment in a Phase 1/2 clinical trial in the second half of 2021.
IC-200: Product Candidate for BEST1-Related IRDs
In April 2019, we entered into an exclusive global license agreement with Penn and UFRF for rights to develop and commercialize IC-200, our novel AAV gene therapy product candidate for the treatment of Best disease and other BEST1-related IRDs. We started developing this product candidate in late 2018 after we entered into an exclusive option agreement with Penn and UFRF for these rights, which we exercised in April 2019 through the license agreement. Investigators at Penn and UFRF tested IC-200 in a naturally occurring autosomal recessive canine model for Best disease, resulting in the reversal of subretinal lesions and micro-detachments associated with the canine disease. The results of this work were published in PNAS in February 2018 in a paper titled: "BEST1 gene therapy corrects a diffuse retina-wide microdetachment modulated by light exposure." We believe the results from these experiments in a naturally occurring canine disease model with distinct phenotypic similarities to human Best disease demonstrate the potential therapeutic benefit of IC-200 for BEST1-related IRDs.
In October 2018, we also entered into a master sponsored research agreement with Penn (which is separate from the master sponsored research agreement for IC-100), facilitated by PCI, pursuant to which we, together with Penn, are conducting additional preclinical studies of IC-200 as well as natural history studies of patients with autosomal dominant and autosomal recessive forms of BEST1-related IRDs.
We are working with a gene therapy CDMO for preclinical and Phase 1/2 clinical supply of IC-200. We are completing manufacturing activities for a cGMP batch of IC-200 produced by our CDMO. We are conducting other IND-enabling activities, including a toxicology study of IC-200. We are planning for a Phase 1/2 clinical trial for IC-200, including site selection and other startup activities. Based on current timelines and subject to successful completion of preclinical development, we plan to file an IND and subject to regulatory review, begin patient enrollment in a Phase 1/2 clinical trial for IC-200 in the second half of 2021.
Minigene Programs
AAV vectors are generally limited as a delivery vehicle by the size of their genetic cargo, which is restricted to approximately 4,700 base pairs of genetic code. The use of minigenes seeks to deliver a smaller but still functional form of a larger gene packaged into a standard-size AAV delivery vector. The goal of minigene therapy is to deliver a gene expressing a protein that, although smaller than the naturally occurring protein, is nonetheless functional for purposes of treating the associated disease.
We are funding several sponsored research programs at UMMS seeking to use a minigene approach to develop new gene therapies for orphan IRDs. We refer to each of these programs by reference to the transgene for which we are seeking to create a minigene therapy. We receive research results from these programs as they become available. UMMS has granted us an option to obtain an exclusive license to any patents or patent applications that result from these programs. We exercised our
36
option rights for the miniCEP290 program and in July 2019 entered into a license agreement with UMass for exclusive development and commercialization rights to patent rights and know-how for this program.
miniCEP290 Program for LCA10
Our miniCEP290 program is targeting LCA10, which is associated with mutations in the CEP290 gene. The naturally occurring CEP290 gene is approximately 8,000 base pairs. In a 2018 publication in Human Gene Therapy, researchers at UMMS presented their findings that injection of a CEP290 minigene into a newborn mouse model for LCA10 resulted in rescue of photoreceptor cells, as evidenced by both anatomical and functional measures. The goal of this sponsored research is to create and evaluate other CEP290 minigene constructs in the mouse model and optimize the effect observed in that publication.
We have been encouraged by the results of the sponsored research we have received to date. One of the new minigene constructs has shown five times longer duration of functional rescue of the photoreceptors as compared to what was observed in the 2018 publication. UMMS has continued experiments to optimize the constructs, which were delayed because of restrictions placed by UMMS on animal research activities as a result of the COVID-19 pandemic. We currently expect to identify a lead construct during the second quarter of 2021.
miniABCA4 Program for STGD1
Our miniABCA4 program is targeting STGD1, which is associated with mutations in the ABCA4 gene. The size of the naturally occurring ABCA4 gene is approximately 7,000 base pairs. UMMS generated and evaluated several ABCA4 minigene constructs in both in vitro and in vivo experiments, which yielded what we believe to be encouraging results. UMMS is conducting additional experiments to optimize the constructs. We expect to receive additional results from the miniABCA4 program during the first half of 2021.
miniUSH2A Program for USH2A-Related IRDs
The miniUSH2A program seeks to develop a mutation independent, minigene therapy for the vision loss associated with USH2A mutations, including vision loss associated with Usher 2A and USH2A-associated nonsyndromatic autosomal recessive retinitis pigmentosa. Some of the activities in this program were delayed as a result of the closure of UMMS animal research laboratories due to the COVID-19 pandemic. We expect to receive preliminary results from this program during the first half of 2021.
Manufacturing
We do not currently own or operate manufacturing facilities for the production of clinical or commercial quantities of Zimura, IC-500, IC-100, IC-200 or any other product candidate we may develop. Although we rely and intend to continue to rely upon third-party contract manufacturing organizations, or CMOs, to produce our products and product candidates, we have personnel with experience to manage the third-party CMOs that we have engaged or may engage to produce our product candidates.
Manufacturing of pharmaceutical and biological products is a process that involves procurement of starting materials, chemical synthesis or cell culture processing in controlled environments, purification and post-production testing and analysis before the product can be released. Manufacturing processes can be complex and difficult to develop, especially for products such as oligonucleotides and gene therapies. Even when a manufacturing process is successfully developed, there are challenges associated with scaling up a manufacturing process to produce quantities sufficient for clinical trials or potential commercial sales and producing high-quality materials consistently using a clearly defined manufacturing process. The manufacture of pharmaceutical and biological products is subject to FDA review and oversight. Having a well-defined process that can be validated is crucial to obtaining FDA approval of any product candidate we may bring forward.
Zimura Manufacturing
The process for manufacturing Zimura consists of chemical synthesis, purification, pegylation, purification and finally freeze drying to form a powder, which is the active pharmaceutical ingredient, or API. Each of these steps involves relatively common unit operations. In a separate process that follows the freeze drying, the Zimura API is dissolved in a liquid solution that includes certain chemical buffers and then is aseptically filled into vials from which the intravitreal injection solution is drawn. This process of rendering the API into a liquid solution and placing it into vials is referred to as fill/finish services.
In early 2017, we completed the small scale manufacture of multiple batches of Zimura drug substance that we are using to support clinical drug supply for the GATHER2 trial and the expanded STAR trial. We have initiated activities in
37
preparation for the scale-up and validation of the manufacturing process for Zimura drug substance with a new manufacturer, with the goal of assessing whether this manufacturer can produce Zimura drug substance at an adequate scale for future potential commercial use. If this manufacturer is successful, we intend for this manufacturer to be our primary supplier of Zimura drug substance. We also recently engaged our historical contract manufacturer for Zimura drug substance, Agilent Technologies, Inc., or Agilent, for scale-up and validation activities. Depending on the success of the scale-up activities by the new manufacturer, we may use either this new manufacturer, Agilent or both for future supply of Zimura drug substance. In addition, regardless of which manufacturer we use, we will need to demonstrate that the drug substance produced through the scaled-up process is analytically comparable to the drug substance we are currently using. We are continuing analytical method development and qualification with our contract manufacturers and laboratories.
In 2020, we engaged a contract manufacturer to provide us with additional supply of finished Zimura drug product to support our needs for the GATHER2 trial and the expanded STAR trial. We expect that this contract manufacturer will be able to supply sufficient finished Zimura drug product for these two clinical trials. In addition, we are planning to make a change to the existing vial used for Zimura drug product, which we believe may allow us to support a more efficient fill/finish operation at a commercial scale. We have been in discussions with our historical fill/finish manufacturer, Ajinomoto Bio-Pharma Services, or Ajinomoto, regarding its capacity to supply us with finished Zimura drug product with the new vial for potential commercial use.
We order the PEG starting material used to make Zimura drug substance from a sole source third-party manufacturer outside the United States. We currently procure the supply on a purchase order basis and are planning to enter into a long-term supply agreement with this manufacturer for the PEG starting material. We are assessing this supplier's capacity to supply the PEG at the scale that we expect we will need for commercial manufacturing.
Gene Therapy Manufacturing
The manufacture of AAV gene therapies requires the use of high quality starting materials, such as plasmids and cells. Plasmids are circular double-stranded DNA sequences that exist separately from a cell's chromosomes and which can be engineered to encode for a specific promoter-transgene combination or a specific AAV Rep-Cap combination. The plasmids and cells are generally sourced from a limited number of qualified suppliers.
The process for producing AAV vectors typically consists of growing the cells, transfection of the cells with appropriate plasmids and harvesting the viral vectors from the cell culture. The subsequent purification process is designed to capture, purify and concentrate the viral vector product while removing process and product-related impurities. The purified AAV vector is then formulated, filtered and filled into vials, from which the injection solution is drawn.
We obtain the plasmids that are used for IC-100 and IC-200 from a single third-party supplier on a purchase order basis. We are working with a gene therapy CDMO for preclinical and Phase 1/2 clinical supply of IC-100 and IC-200 drug substance and drug product. In 2020, this CDMO produced a cGMP batch of IC-100, which we believe will be sufficient for our expected needs for a Phase 1/2 clinical trial. In early 2021, this CDMO also produced a cGMP batch of IC-200, which we believe will be sufficient for our expected needs for a Phase 1/2 clinical trial.
Human Capital
Our Workforce
As of January 31, 2021, we had 57 full-time employees, compared to 38 full-time employees as of January 31, 2020. These employees support key areas of our business and operations, including clinical operations, regulatory affairs, drug safety, data management, medical affairs, scientific research, process and analytical development, drug substance and drug product manufacturing, quality control, materials and supply chain management, and quality assurance, as well as our general and administrative functions and public company infrastructure. We plan to continue to hire strategically to support key areas of our business. The following are additional data about our full-time employees:
•45 are in research and development or related operations;
•12 have M.D. or Ph.D. degrees;
•30 self-identify as women;
•22 self-identify as racial or ethnic minorities; and
38
•31 have been employed with us for four years or longer.
In addition to our full-time employees, we engage various consultants and advisors to support key areas of our business, including formulating our research and development, manufacturing, commercialization and lifecycle management strategies. Many of these consultants and advisors have specialized expertise that also makes them attractive for other companies. We generally engage them as independent contractors and they are generally free to work for other companies, subject to the terms of any non-compete arrangements that we enter into with them.
Human Capital Initiatives
During the COVID-19 pandemic, we increased our efforts to support our employees and transitioned to full-time remote working in March 2020. We conducted numerous surveys over the course of the year to gauge employee sentiment and understand their needs. Early in the pandemic, we provided employees with technology and training sessions to support remote working. We took efforts to enhance company communication, such as holding weekly company meetings to provide business updates and provide a forum for guest speakers, including several offering education in best practices for remote working and general wellness. Our employees adopted various software tools to support virtual communication and collaboration. We continued to provide flexible work policies to support our employees and have engaged an outside vendor offering virtual fitness and wellness programs for our employees. We currently expect to continue working remotely for the foreseeable near future.
In 2020, we continued to develop our new employee integration and professional development programs. Most of our newly hired employees in 2020 joined us remotely, and we have revamped our new employee orientation program and instituted a buddy system for new employees. We provided training to our employees on our amended Code of Conduct and Business Ethics and other pertinent topics such as data privacy. We revised our year-end performance review and metrics system for employees during 2020. In 2021, we plan to offer additional training and leadership development opportunities for our employees.
In mid-2020, we formed an employee committee on diversity, equity and inclusion, or CDEI, to assess issues of diversity, equity and inclusion among our workforce and provide recommendations. We engaged an academic consultant to help support this initiative, including by providing education and leading focus groups with our employees. In 2021, we are planning to implement a number of suggestions from the CDEI based on feedback from our employees and the consultant.
Sales and Marketing
We expect that our commercial strategy for any of our product candidates, including whether to retain commercial rights and market and sell the product candidate ourselves or to utilize collaboration, distribution or other marketing arrangements with third parties in some or all geographic markets, will be determined based on a variety of factors, including the size and nature of the patient population, the disease area, the particular indication for which the product candidate is approved, the territory in which the product candidate may be marketed and the commercial potential for such product candidate. We are currently developing Zimura and IC-500 for GA secondary to AMD, which is a condition affecting a relatively large number of individuals, and we are also developing Zimura for STGD1, which is a condition affecting a more limited number of individuals. Our gene therapy programs are currently being developed for orphan IRDs with a limited number of affected individuals. If any of our product candidates are approved, the size and nature of the affected patient population will be an important factor in our commercial strategy.
In addition, our commercial strategy will vary depending on whether the disease is typically treated by general ophthalmology practitioners, specialists, such as retina specialists, or other sub-specialists, and the degree and potential degree of acceptance of our product candidate by the relevant physicians in various markets. For example, in the United States, retina specialists perform most of the medical procedures involving diseases of the back of the eye. Intravitreal injection and subretinal injection are specialized procedures. In the vast majority of cases in the United States, retina specialists perform intravitreal injections and highly specialized retina surgeons perform subretinal injections. We believe that retina specialists and retina surgeons in the United States are sufficiently concentrated such that we could effectively promote an approved product candidate to these specialists with a targeted specialty sales and marketing group. For example, in the United States and Europe, retina specialists who see patients with IRDs, as well as their patients, are generally concentrated in a limited number of large, academic research institutions.

Competition
The development and commercialization of new drug products is highly competitive. We face competition with respect to our product candidates from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies, as well as generic and biosimilar companies, worldwide. Potential competitors also include academic institutions, government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and commercialization. Some of these competitive products and therapies are based on scientific approaches that are the same as or similar to our approaches, and others are based on entirely different approaches. We also will face similar competition with respect to any product candidates that we may seek to develop or commercialize in the future. In particular, many companies are pursuing gene therapy approaches for orphan and age-related retinal diseases.
Based on publicly available information, we are aware of the following research and development programs that may be competitive with programs we are pursuing. Other competitive programs may exist of which we are not aware.
Competitive considerations for GA or dry AMD:
•We are aware that LumiThera, Inc. has a medical device using its LT-300 light delivery system, which is approved in the European Union for the treatment of dry AMD. In addition, there are a number of products in preclinical and clinical development by third parties to treat GA or dry AMD. In general, these product candidates can be categorized based on their proposed mechanisms of action. The mechanisms of action for these product candidates include complement system and inflammation suppression, visual cycle modulators, antioxidants and neuroprotectants, cell and gene therapies and vascular perfusion enhancers. We are aware that Alexion Pharmaceuticals, Inc., Annexon Inc., Apellis Pharmaceuticals, Inc., or Apellis, Applied Genetic Technologies Corporation, or AGTC, Biogen Inc., Gemini Therapeutics, Inc., Gyroscope Therapeutics, IONIS Pharmaceuticals, Inc. (in collaboration with Roche AG), Janssen Pharmaceuticals Inc. (which acquired its program through the acquisition of Hemera Biosciences, LLC), MorphoSys AG, NGM Biopharmaceuticals Inc. and Novartis AG each have complement inhibitors in development for GA or dry AMD, including, in the cases of Gemini Therapeutics, Gyroscope Therapeutics and Janssen Pharmaceuticals, complement inhibitor gene therapies and AGTC and Gemini Therapeutics each has a research program on complement factor H gene therapy. We believe that the most advanced of these programs is Apellis's pegylated, synthetic peptide targeting complement protein C3. In July 2020, Apellis announced that it had completed patient enrollment in its Phase 3 program with a total of 1,259 patients, and expects to announce top-line data from the trials in the third quarter of 2021. If Apellis's Phase 3 program for its C3 complement inhibitor product candidate is successful, it is likely that Apellis would obtain marketing approval for its product candidate in advance of when we could reasonably expect to obtain marketing approval for Zimura in GA or IC-500 in GA, if at all. Moreover, we are aware that several other companies, including Allergan Inc., Allegro Ophthalmics, LLC, Alkeus Pharmaceuticals Inc., Astellas Pharma Inc., Boehringer Ingelheim, EyePoint Pharmaceuticals, Inc., Lineage Cell Therapeutics, Inc., Roche AG and Stealth BioTherapeutics Corp., are pursuing development programs for the treatment GA or dry AMD using different mechanisms of action outside of the complement system, including Genentech, Inc. (an affiliate of Roche AG) and Gemini Therapeutics, which are pursuing HtrA1 inhibition as a mechanism of action. We believe that the most advanced HtrA1 inhibitor program in development is Genentech's monoclonal antibody HtrA1 inhibitor, which is currently being studied in a Phase 2 clinical trial.
Competitive considerations for Stargardt disease:
•There are a number of products in preclinical research and clinical development by third parties to treat Stargardt disease. We are aware that AGTC, Alkeus Pharmaceuticals, Inc., Beam Therapeutics Inc., Generation Bio Co., Kubota Vision Inc. (formerly Acucela), Lin BioScience, Inc., Nightstar Therapeutics plc (prior to its acquisition by Biogen), or Nightstar, ProQR Therapeutics N.V., or ProQR, and Spark Therapeutics each have research or development programs in Stargardt disease. Three of these programs, Alkeus, Kubota and Lin BioScience, are exploring the use of oral therapeutics, while AGTC, Nightstar and Spark are each using a gene therapy approach, Beam is using a base editing approach, and ProQR is using an RNA based approach. Kubota’s product candidate, to which the FDA and the EMA granted orphan drug designation in August 2020, is in Phase 3 development while Alkeus’s product candidate is in Phase 2 development. In addition, several academic organizations have early stage programs in Stargardt disease.
Competitive considerations for RHO-adRP:
•We are aware that ProQR is developing an RNA-based therapeutic for RHO-adRP, for which it is currently conducting a Phase 1/2 clinical trial. Ocugen, Inc. is developing a gene therapy for RHO-adRP, for which the FDA granted orphan
40
drug designation in July 2020. In addition, prior to its acquisition by Biogen, Nightstar had a preclinical AAV gene therapy program in RHO-adRP. 4D Molecular Therapeutics is developing an intravitreal gene therapy for RHO-adRP. Editas Medicine, Inc. is exploring a potential gene editing program in this disease. We are also aware that multiple academic institutions have early stage gene therapy development programs in RHO-adRP.
Competitive considerations for BEST1-related IRDs:
•We are aware that, prior to its acquisition by Biogen, Nightstar had a preclinical AAV gene therapy program for one or more BEST1-related IRDs.
Competitive considerations for LCA10:
•We are aware that Editas Medicine, Inc. has a gene editing program for LCA10, for which a Phase 1/2 clinical trial is ongoing, ProQR is developing an RNA-based therapeutic for LCA10 that is currently in Phase 2/3 development, Generation Bio Co. has a preclinical program that utilizes ceDNA technology to target LCA10 and Oxford Biomedica plc is developing a lentiviral gene therapy program for LCA10 that is in preclinical development. In addition, several academic institutions have preclinical programs in LCA10.
Competitive considerations for USH2A-related IRDs:
•There are a number of products in preclinical research and clinical development by third parties to treat USH2A-related IRDs. We are aware that ProQR is pursuing two RNA based approaches for different mutations causing Usher 2A, one of which is currently in Phase 1/2 clinical development and the other of which is in preclinical development. We are also aware that Editas Medicine, Inc. and Odylia Therapeutics are exploring potential programs in USH2A-related IRDs.
Intellectual Property
Our success depends in part on our ability to obtain and maintain proprietary protection for our product candidates, technology and know-how, to operate without infringing the proprietary rights of others and to prevent others from infringing our proprietary rights. We seek to protect our proprietary position, among other methods and where patent protection is available, by filing U.S. and certain foreign patent applications related to our proprietary technology, inventions and improvements that are important to the development of our business, and by maintaining our issued patents. For our collaborative gene therapy sponsored research programs, we are generally relying on our university collaborators to perform research and generate data to support new patent applications, and to file, prosecute and maintain any patents or patent applications resulting from the sponsored research. We also rely upon trade secrets, know-how, continuing technological innovation and in-licensing opportunities to develop and maintain our proprietary position.
Our patent portfolio includes the following:
•patents and patent applications in-licensed from Archemix Corp., or Archemix:
•patents covering Zimura's composition-of-matter, which have issued in the United States, the countries covered by the European Patent Organisation, which we refer to as the EPO Countries, Japan and certain other jurisdictions, and which are expected to expire in Japan in 2026 and elsewhere in 2025; and patent applications covering Zimura's composition-of-matter, which are pending in certain other jurisdictions, and which, if granted, are expected to expire in 2025; and
•patents covering the treatment of certain complement mediated disorders with Zimura, Zimura for use in a method of treating certain complement mediated disorders or a composition comprising Zimura for treating certain complement mediated disorders, which have issued in the United States, the EPO Countries, Japan and certain other jurisdictions, and which are expected to expire in the United States and Japan in 2026 and elsewhere in 2025; and
•patent applications owned by IVERIC bio, Inc.:
•patent applications covering formulations, methods of use for treating GA, Stargardt disease and other conditions, and other proprietary technology relating to Zimura, which are pending in the United States,
41
the EPO Countries, Japan and certain other jurisdictions, and which, if granted, are expected to expire in 2034; and
•patent applications owned by our subsidiary Orion Ophthalmology LLC, or Orion:
•three families of composition-of-matter and method-of-treatment patent applications covering IC-500 and other HtrA1 inhibitors owned by Orion, which are pending in the United States, the EPO Countries, Japan and certain other jurisdictions, and which, if granted, are expected to expire in 2037; and
•patent applications in-licensed from UFRF and Penn:
•two families of composition-of-matter and method-of-treatment patent applications relating to the proprietary RHO-adRP AAV technology of UFRF and Penn, which are pending in the United States, the EPO Countries, Japan and certain other jurisdictions, and which, if granted, are expected to expire in 2037 and 2039, respectively; and
•patent applications covering methods of treating autosomal dominant BEST1-related IRDs and autosomal recessive BEST1-related IRDs, which are pending in the Patent Cooperation Treaty jurisdictions, and which, if granted, are expected to expire in 2041; and
•patent applications in-licensed from UMass:
•two families of composition-of-matter and method-of-treatment patent applications relating to certain proprietary minigene technology for the treatment of diseases associated with mutations in the CEP290 gene, which are pending in the United States, the EPO Countries, Japan and certain other jurisdictions, and which, if granted, are expected to expire in 2038 and 2040, respectively.
The term of individual patents depends upon the legal term for patents in the countries in which they are granted. In most countries, including the United States, the patent term is generally 20 years from the earliest claimed filing date of a non-provisional patent application in the applicable country. In the United States, a patent’s term may, in certain cases, be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the U.S. Patent and Trademark Office in examining and granting a patent, or may be shortened if a patent or patent application claims patentably indistinct subject matter as another commonly owned patent or patent application having an earlier expiration date and the patentee terminally disclaims the portion of the term beyond such earlier expiration date. The Hatch-Waxman Act permits a patent term extension of up to five years beyond the expiration date of a U.S. patent as partial compensation for the length of time a drug is undergoing clinical development or under regulatory review while the patent is in force. A patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, only one patent applicable to each regulatory review period may be extended and only those claims covering the approved drug, a method for using it or a method for manufacturing it may be extended.
Similar provisions are available in the EPO Countries and certain other foreign jurisdictions to extend the term of a patent that covers an approved drug. In the future, if and when our product candidates receive approval by the FDA or foreign regulatory authorities, we expect to apply for patent term extensions on issued patents covering those products, depending upon the length of the clinical trials for each drug and other factors. The expiration dates referred to above are without regard to potential patent term extension or other market exclusivity that may be available to us. See "—Government Regulation and Product Approvals" below for a description of market exclusivity mechanisms that may be available to us.
We may rely, in some circumstances, upon trade secrets to protect our technology. However, trade secrets can be difficult to protect. We seek to protect our proprietary technology and processes, in part, by confidentiality agreements with our employees, consultants, scientific advisors and contractors. We also seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and electronic security of our information technology systems.
42
Licensing and Other Arrangements
We are party to a number of license, acquisition and other agreements that have granted us rights to develop our product candidates and conduct our research and development programs. These agreements generally impose license fee, milestone payment, royalty payment and diligence obligations on us. Our material in-license and acquisition agreements are described below.
In the future, we may enter into additional acquisition or license agreements, particularly if we choose to acquire or in-license additional product candidates or other technologies and further expand our product pipeline. We expect that any future acquisition or license agreements would impose similar obligations on us. In the future, we may also enter into agreements to out-license intellectual property to our collaboration and research partners to assist in the development and, if approved, commercialization of our product candidates. We may out-license certain rights to any of our product candidates if we believe the arrangement could assist us in the development or potential commercialization of such product candidate and would otherwise help us pursue our business plan and strategic goals.
Zimura - Archemix C5 License Agreement
In September 2011, we entered into an amended and restated exclusive license agreement with Archemix relating to anti-C5 aptamers, which we refer to as the C5 License Agreement. The C5 License Agreement superseded a July 2007 agreement between us and Archemix. Under the C5 License Agreement, we hold exclusive worldwide licenses, subject to certain pre–existing rights, under specified patents and technology owned or controlled by Archemix to develop, make, use, sell, offer for sale, distribute for sale, import and export pharmaceutical products comprised of or derived from an anti-C5 aptamer for the prevention, treatment, cure or control of human indications, diseases, disorders or conditions of the eye, adnexa of the eye, orbit and optic nerve, other than certain expressly excluded applications.
Financial Terms
In connection with the C5 License Agreement, as amended, we paid Archemix an upfront licensing fee of $1.0 million and issued to Archemix an aggregate of 2,000,000 shares of our series A-1 preferred stock and 500,000 shares of our series B-1 preferred stock. We have paid Archemix an aggregate of $9.0 million in fees based on our achievement of specified clinical milestone events under the C5 License Agreement, including two milestone payments of $1.0 million and $6.0 million triggered by the positive 12-month data from, and by completion of, the GATHER1 trial, which we paid in March 2020 and October 2020, respectively.
Under the C5 License Agreement, for each anti-C5 aptamer product that we may develop under the agreement, including Zimura, we are obligated to make additional payments to Archemix of up to an aggregate of $50.5 million if we achieve specified development, clinical and regulatory milestones, with $24.5 million of such payments relating to a first indication, $23.5 million of such payments relating to second and third indications and $2.5 million of such payments relating to sustained delivery applications. Under the C5 License Agreement, we are also obligated to make additional payments to Archemix of up to an aggregate of $22.5 million if we achieve specified commercial milestones based on net product sales of all anti-C5 products licensed under the agreement. We are also obligated to pay Archemix a double-digit percentage of specified non-royalty payments we may receive from any sublicensee of our rights under the C5 License Agreement. We are not obligated to pay Archemix a running royalty based on net product sales in connection with the C5 License Agreement.
Diligence Obligations
We are required to exercise commercially reasonable efforts in developing and commercializing at least one anti-C5 aptamer product and in undertaking actions required to obtain regulatory approvals necessary to market such product in the United States, the European Union, and Japan, and in such other markets where we determine that it is commercially reasonable to do so.
Term and Termination
Unless earlier terminated, the C5 License Agreement will expire upon the latest of 12 years after the first commercial sale in any country of the last licensed product, the expiration of the last-to-expire valid claim of the licensed patents that covers a licensed product, and the date on which no further payments of sublicensing income are to be received by us.
Either we or Archemix may terminate the C5 License Agreement if the other party materially breaches the agreement and the breach remains uncured for a specified period. Archemix may also terminate the C5 License Agreement, or may convert
43
our exclusive license under the agreement to a non-exclusive license, if we challenge or assist a third party in challenging the validity or enforceability of any of the patents licensed under the agreement. We may terminate the agreement at any time and for any or no reason effective at the end of a specified period following our written notice of termination to Archemix.
IC-500 - Inception 4 Merger Agreement
In October 2018, we acquired IC-500 and a number of other HtrA1 inhibitors through our acquisition of Inception 4, Inc., or Inception 4, which was previously a privately held biotechnology company controlled by funds owned by Versant Ventures. We and Inception 4 entered into an agreement and plan of merger, which we refer to as the Inception 4 Merger Agreement, pursuant to which we acquired Inception 4 through a merger transaction, referred to as the Inception 4 Merger. Following the Inception 4 Merger, Inception 4 was merged into our wholly-owned subsidiary Orion, which currently owns the rights to IC-500 and the other HtrA1 inhibitors acquired in the Inception 4 Merger.
As upfront consideration for the Inception 4 Merger, the former equityholders of Inception 4 received 5,044,201 shares of our common stock, and in December 2018, they received an additional 130,526 shares of our common stock following finalization of customary post-closing adjustments. As part of the transaction, we received approximately $6.1 million in cash.
Contingent Consideration
In addition, pursuant to the Inception 4 Merger Agreement, the former equityholders of Inception 4 will be entitled to receive contingent future payments from us based on the achievement of certain clinical and regulatory milestones of up to an aggregate maximum amount of $105 million, with $45 million of such potential payments relating to GA and $60 million of such potential payments relating to wet AMD. These future milestone payments will be payable in the form of shares of our common stock, calculated based on the price of our common stock over a five-trading day period preceding the achievement of the relevant milestone, unless and until the issuance of such shares would, together with all other shares issued in connection with the Inception 4 Merger, exceed an overall maximum limit of approximately 7.2 million shares, which is equal to 19.9% of the number of issued and outstanding shares of our common stock as of the close of business on the business day prior to the closing date of the Inception 4 Merger, and will be payable in cash thereafter.
Diligence Obligation
We agreed to use commercially reasonable efforts to perform the activities described in an agreed-upon development plan outlining certain activities for developing at least one HtrA1 inhibitor for the treatment of GA. Our maximum aggregate liability for any and all breaches of our obligation under the Inception 4 Merger Agreement to use commercially reasonable efforts to develop an HtrA1 inhibitor is limited to $5 million.
Other Terms and Conditions
The Inception 4 Merger Agreement contains customary representations, warranties and covenants for both Inception 4 and our company as the purchaser. The representations and warranties generally survived until the first anniversary of the closing date, with certain specified representations and warranties surviving to 30 months after the closing date and other specified representations and warranties surviving to the expiration of the applicable statute of limitations. The Inception 4 Merger Agreement also contains customary indemnification provisions whereby the former equityholders of Inception 4 will indemnify us and certain affiliated parties for any losses arising out of breaches of the representations, warranties and covenants of Inception 4 under the Inception 4 Merger Agreement; pre-closing tax matters; appraisal claims of former Inception 4 stockholders; any pre-closing indebtedness or expenses not previously adjusted for at the closing; fraud with respect to representations and warranties of Inception 4; and certain other matters.
License Agreement with UFRF and Penn for IC-100
In June 2018, we entered into an exclusive global license agreement with UFRF and Penn, which we refer to as the RHO-adRP License Agreement. Under the RHO-adRP License Agreement, UFRF and Penn granted us a worldwide, exclusive license under specified patent rights and a worldwide, non-exclusive license under specified know-how, including specified preclinical data, to manufacture, develop and commercialize certain AAV gene therapy products for the treatment of rhodopsin-mediated diseases. The rights granted under the RHO-adRP License Agreement included certain patent rights covering IC-100, our novel AAV gene therapy product candidate intended to treat RHO-adRP.
We may grant sublicenses of the licensed patent rights and know-how without the consent of the UFRF and Penn to certain affiliates and to biopharmaceutical companies that have a minimum market capitalization at the time such sublicense is granted and may otherwise grant sublicenses of the licensed patent rights and know-how with the consent of UFRF and Penn, not to be unreasonably withheld.
44
Diligence Obligations
We agreed to use commercially reasonable efforts to pursue an agreed-upon development plan with the intent to develop a licensed product for sale within at least the United States and two major European countries and, subject to obtaining marketing approval, to commercialize a licensed product in at least the United States and two major European countries. In addition, we agreed to meet specified development and commercial milestones with respect to a licensed product by specified dates, as the same may be extended under the terms of the RHO-adRP License Agreement.
Financial Terms
In June 2018, we paid a $0.5 million upfront license issuance fee in connection with entry into the agreement, as well as accrued patent prosecution expenses of approximately $30 thousand. Under the agreement, we agreed to pay an annual license maintenance fee in the low double-digit thousands of dollars, which will be payable on an annual basis until the first commercial sale of a licensed product. In addition, we agreed to reimburse UFRF for the costs and expenses of patent prosecution and maintenance related to the licensed patent rights.
We further agreed to pay UFRF, on behalf of both licensors, up to an aggregate of $23.5 million if we achieve specified clinical, marketing approval and reimbursement approval milestones with respect to a licensed product and additionally, up to an aggregate of $70.0 million if we achieve specified commercial sales milestones with respect to a licensed product.
We are also obligated to pay UFRF, on behalf of both licensors, royalties at a low single-digit percentage of net sales of licensed products. Such royalties are subject to customary reductions for lack of patent coverage and loss of regulatory exclusivity. In addition, such royalties with respect to any licensed product in any country may be offset by a specified portion of any royalty payments actually paid by us with respect to such licensed product in such country under third-party licenses for patent rights or other intellectual property rights that are necessary to manufacture, develop and commercialize the licensed product in such country. Our obligation to pay royalties under the RHO-adRP License Agreement will continue on a licensed product-by-licensed product and country-by-country basis until the latest of:
•the expiration of the last-to-expire licensed patent rights covering a licensed product in the country of sale;
•the expiration of regulatory exclusivity covering a licensed product in the country of sale; and
•ten years from the first commercial sale of the applicable licensed product in the country of sale.
Beginning on the earlier of the calendar year following the first commercial sale of a licensed product and the first business day of 2031, we are also obligated to pay certain minimum royalties, not to exceed an amount in the low hundreds of thousands of dollars on an annual basis, which minimum royalties are creditable against our royalty obligation with respect to net sales of licensed products due for the year in which the minimum royalty is paid.
If we or an affiliate sublicenses any of the licensed patent rights to a third party, we will be obligated to pay UFRF, on behalf of both licensors, a low double-digit percentage of the consideration received in exchange for such sublicense, with the applicable percentage based upon the stage of development of the sublicensed product at the time we or the applicable affiliate enters into the sublicense.
If we receive a rare pediatric disease priority review voucher from the FDA in connection with obtaining marketing approval for a licensed product and we subsequently use such priority review voucher in connection with a different product candidate, we will be obligated to pay UFRF, on behalf of both licensors, aggregate payments in the low double-digit millions of dollars based on certain marketing approval and commercial sales milestones with respect to such other product candidate. In addition, if we sell such a priority review voucher to a third party, we will be obligated to pay UFRF, on behalf of both licensors, a low double-digit percentage of any consideration received from such third party in connection with such sale.
Term and Termination
Unless earlier terminated by us, the RHO-adRP License Agreement will expire upon the expiration of our obligation to pay royalties to UFRF on net sales of licensed products. We may terminate the agreement at any time for any reason upon prior written notice to UFRF. Penn or UFRF may terminate the agreement if we materially breach the agreement and do not cure such breach within a specified cure period, if we experience a specified insolvency event, if we cease to carry on the entirety of our business related to the licensed patent rights, if we cease for more than four consecutive quarters to make any payment of earned royalties on net sales of licensed products following the commencement of commercialization thereof, unless such cessation is based on safety concerns that we are actively attempting to address, or if we or an affiliate challenges or assists a third party in challenging the validity, scope, patentability, and/or enforceability of the licensed patent rights.
45
Following any termination of the agreement prior to expiration of the term of the agreement, all rights to the licensed patent rights and know-how granted to us will revert to UFRF and Penn.
License Agreement with Penn and UFRF for IC-200
In April 2019, we entered into an exclusive global license agreement, which we refer to as the BEST1 License Agreement, with Penn and UFRF. We entered into the BEST1 License Agreement by exercising our exclusive option rights under an option agreement that we previously entered into with Penn and UFRF in October 2018. Under the BEST1 License Agreement, Penn and UFRF granted us a worldwide, exclusive license under specified patent rights and specified know-how and a worldwide, non-exclusive license under other specified know-how to research, develop, manufacture and commercialize certain AAV gene therapy products, including IC-200, for the treatment of Best disease and other BEST1-related IRDs.
We have agreed to use commercially reasonable efforts to pursue an agreed-upon development plan with the intent to develop a licensed product for sale within at least the United States and two major European countries and, subject to obtaining marketing approval, to commercialize such product in at least the United States and two major European countries. In addition, we have agreed to meet specified development and regulatory milestones with respect to a licensed product by specified dates, as the same may be extended under the terms of the agreement.
We may grant sublicenses of the licensed patent rights and know-how, without the consent of Penn or UFRF, to certain affiliates and to biopharmaceutical companies that have a minimum market capitalization at the time such sublicense is granted, and may otherwise grant sublicenses to the licensed patent rights and know-how with the consent of Penn and UFRF, not to be unreasonably withheld.
Financial Terms
In May 2019, we paid Penn, for the benefit of Penn and UFRF, a $0.2 million upfront license issuance fee, which was recorded as a research and development expense, and we paid UFRF accrued patent prosecution expenses of approximately $18 thousand, which was recorded as a general and administrative expense. We have also agreed to pay Penn, for the benefit of Penn and UFRF, an annual license maintenance fee in the low double-digit thousands of dollars, which fee will be payable on an annual basis until the first commercial sale of a licensed product. In addition, we have agreed to pay Penn, for the benefit of Penn and UFRF, a one-time patent grant fee in the low triple-digit thousands of dollars, upon the issuance of a U.S. patent that claims inventions disclosed in the licensed patent rights or know-how or inventions generated under certain related sponsored research agreements with Penn or UFRF, and that is exclusively licensed to us. Furthermore, we have agreed to reimburse Penn and UFRF for the costs and expenses of patent prosecution and maintenance related to the licensed patent rights.
We have further agreed to pay Penn, for the benefit of Penn and UFRF, up to an aggregate of $15.7 million if we achieve specified clinical, marketing approval and reimbursement approval milestones with respect to one licensed product, and up to an aggregate of an additional $3.1 million if we achieve these same milestones with respect to a different licensed product. In addition, we have agreed to pay Penn, for the benefit of Penn and UFRF, up to an aggregate of $48.0 million if we achieve specified commercial sales milestones with respect to one licensed product, and up to an aggregate of an additional $9.6 million if we achieve these same milestones with respect to a different licensed product.
We are also obligated to pay Penn, for the benefit of Penn and UFRF, royalties at a low single-digit percentage of net sales of licensed products. Such royalties are subject to customary deductions, credits, and reductions for lack of patent coverage and loss of regulatory exclusivity. In addition, such royalties with respect to any licensed product in any country may be offset by a specified portion of any royalty payments actually paid by us with respect to such licensed product in such country under third-party licenses to patent rights or other intellectual property rights that are necessary to research, develop, manufacture and commercialize the licensed product in such country. Our obligation to pay royalties under the BEST1 License Agreement will continue on a licensed product-by-licensed product and country-by-country basis until the latest of:
•the expiration of the last-to-expire licensed patent rights covering the sale of the applicable licensed product in the country of sale;
•the expiration of regulatory exclusivity covering the applicable licensed product in the country of sale; and
•10 years from the first commercial sale of the applicable licensed product in the country of sale.
Beginning on the earlier of the calendar year following the first commercial sale of a licensed product and calendar year 2032, we are also obligated to pay certain minimum royalties, not to exceed an amount in the mid tens of thousands of dollars on an annual basis, which minimum royalties are creditable against our royalty obligation with respect to net sales of licensed products due in the year the minimum royalty is paid.
46
If we or any of our affiliates sublicense any of the licensed patent rights to a third party, we will be obligated to pay Penn, for the benefit of Penn and UFRF, a high single-digit to a mid ten's percentage of the consideration received in exchange for such sublicense, with the applicable percentage based upon the stage of development of the sublicensed product at the time we or the applicable affiliate enters into the sublicense.
If we receive a rare pediatric disease priority review voucher from the FDA in connection with obtaining marketing approval for a licensed product and we subsequently use such priority review voucher in connection with a different product candidate outside the scope of the BEST1 License Agreement, we will be obligated to pay Penn, for the benefit of Penn and UFRF, aggregate payments in the low double-digit millions of dollars based on certain approval and commercial sales milestones with respect to such other product candidate. In addition, if we sell such a priority review voucher to a third party, we will be obligated to pay Penn, for the benefit of Penn and UFRF, a high single-digit percentage of any consideration received from such third party in connection with such sale.
Term and Termination
The BEST1 License Agreement, unless earlier terminated by us or Penn or UFRF, will expire upon the expiration of our obligation to pay royalties to Penn, for the benefit of Penn and UFRF, on net sales of licensed products. Before the effectiveness of an IND for a licensed product, we may terminate the BEST1 License Agreement with respect to such licensed product or in its entirety, at any time for any reason upon prior written notice to Penn and UFRF. Following the effectiveness of an IND for a licensed product, we may terminate the BEST1 License Agreement with respect to such licensed product by providing Penn prior written notice and a certification that we are ceasing all use, research and development and commercialization of such licensed product, subject to certain limited exceptions. We may also terminate the BEST1 License Agreement if Penn or UFRF materially breaches the BEST1 License Agreement and does not cure such breach within a specified cure period.
Penn or UFRF may terminate the BEST1 License Agreement if we materially breach the BEST1 License Agreement and do not cure such breach within a specified cure period, if we experience a specified insolvency event, if we cease to carry on the entirety of our business related to the licensed patent rights, if we cease for more than four consecutive quarters to make any payment of earned royalties on net sales of licensed products following the commencement of commercialization thereof, unless such cessation is based on safety concerns that we are actively attempting to address, or if we, any of our affiliates or any of our sublicensees challenge or assist a third party in challenging the validity, scope, patentability, and/or enforceability of the licensed patent rights. If we materially breach certain diligence obligations under the BEST1 License Agreement with respect to only one licensed product, then Penn and UFRF may only terminate our rights and licenses under the BEST1 License Agreement for such licensed product, but not for other licensed products.
Following any termination of the BEST1 License Agreement prior to expiration of the term of the BEST1 License Agreement, all rights to the licensed patent rights and know-how that Penn and UFRF granted to us will revert to Penn and UFRF.
License Agreement with UMass for the miniCEP290 Program
In July 2019, we entered into an Exclusive License Agreement, which we refer to as the miniCEP290 License Agreement, with UMass. We entered into the miniCEP290 License Agreement by exercising our exclusive option rights under an option agreement and a sponsored research agreement that we previously entered into with UMass in February 2018. Under the miniCEP290 License Agreement, UMass granted us a worldwide, exclusive license under specified patent rights and specified biological materials and a non-exclusive license under specified know-how to make, have made, use, offer to sell, sell, have sold and import products for the treatment of diseases associated with mutations in the CEP290 gene, including LCA10. We may grant sublicenses of the licensed patent rights and know-how without the consent of UMass.
We have agreed to use diligent efforts to develop licensed products and to introduce such licensed products into the commercial market. Subject to obtaining marketing approval, we agreed to make any approved licensed product reasonably available to the public. In addition, we have agreed to meet specified development and regulatory milestones with respect to a licensed product by specified dates, as the same may be extended under the terms of the miniCEP290 License Agreement.
Financial Terms
In July 2019, we issued to UMass 75,000 shares of our common stock following execution of the miniCEP290 License Agreement pursuant to an exemption from registration afforded by Section 4(a)(2) of the Securities Act of 1933, as amended, or the Securities Act. In September 2019, we paid UMass a $0.4 million upfront license fee, which was recorded as a research and development expense, and we paid UMass accrued patent prosecution expenses of approximately $18 thousand, which was recorded as a general and administrative expense.
47
We have also agreed to pay UMass an annual license maintenance fee in the low double-digit thousands of dollars, which fee will be payable on an annual basis until the expiration of the royalty term for the licensed products. Furthermore, we have agreed to reimburse UMass for the costs and expenses of patent prosecution and maintenance related to the licensed patent rights.
We have further agreed to pay UMass up to an aggregate of $14.75 million in cash and issue up to 75,000 shares of our common stock if we achieve specified clinical and regulatory milestones with respect to a licensed product. In addition, we have agreed to pay UMass up to an aggregate of $48.0 million if we achieve specified commercial sales milestones with respect to a licensed product.
We are also obligated to pay UMass royalties at a low single-digit percentage of net sales of licensed products. Our obligation to pay royalties under the miniCEP290 License Agreement will continue on a licensed product-by-licensed product and country-by-country basis until the later of: (a) the expiration of the last-to-expire licensed patent rights covering the sale of the applicable licensed product in the country of sale, or (b) 10 years from the first commercial sale of the applicable licensed product in the country of sale. Beginning with the calendar year following receipt of marketing approval for a licensed product, we are also obligated to pay certain minimum royalties, not to exceed an amount in the mid-double-digit thousands of dollars on an annual basis, which minimum royalties are creditable against our royalty obligation with respect to net sales of licensed products due in the year the minimum royalty is paid.
If we or any of our affiliates sublicenses any of the licensed patent rights or know-how to a third party, we will be obligated to pay UMass a high single-digit to a mid-tens percentage of the consideration received in exchange for such sublicense, with the applicable percentage based upon the stage of development of the licensed products at the time we or the applicable affiliate enters into the sublicense.
If we receive a rare pediatric disease priority review voucher, or a priority review voucher, from the FDA in connection with obtaining marketing approval for a licensed product, and we subsequently use such priority review voucher in connection with a different product candidate outside the scope of the miniCEP290 License Agreement, we will be obligated to pay UMass a low-tens percentage of the fair market value of the priority review voucher at the time of approval of such product candidate and a low-twenties percentage of the fair market value of the priority review voucher at the time of achievement of a specified commercial sales milestone for such other product candidate. In addition, if we sell such a priority review voucher to a third party, we will be obligated to pay UMass a low-thirties percentage of any consideration received from such third party in connection with such sale.
Term and Termination
The miniCEP290 License Agreement, unless earlier terminated by us or UMass, will expire upon the expiration of our obligation to pay royalties to UMass on net sales of licensed products. We may terminate the miniCEP290 License Agreement at any time for any reason upon prior written notice to UMass. We may also terminate the miniCEP290 License Agreement if UMass materially breaches the miniCEP290 License Agreement and does not cure such breach within a specified cure period.
UMass may terminate the miniCEP290 License Agreement if we materially breach the miniCEP290 License Agreement and do not cure such breach within a specified cure period.
Following any termination of the miniCEP290 License Agreement prior to expiration of the term of the miniCEP290 License Agreement, all rights to the licensed patent rights and know-how that UMass granted to us will revert to UMass.
Government Regulation and Product Approvals
Government authorities in the United States, at the federal, state and local level, and in other countries and jurisdictions, including the European Union, extensively regulate, among other things, the research, development, testing, manufacture, pricing, quality control, approval, packaging, storage, recordkeeping, labeling, advertising, promotion, distribution, marketing, post-approval monitoring and reporting, and import and export of pharmaceutical products. The processes for obtaining marketing approvals in the United States and in foreign countries and jurisdictions, along with subsequent compliance with applicable statutes and regulations and other legal requirements of regulatory authorities, require the expenditure of substantial time and financial resources.
Review and Approval of Drugs and Biologics in the United States
In the United States, the FDA approves and regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and implementing regulations. Biologic products, including gene therapy products, are licensed for marketing under the Public Health Service Act, or PHSA. The failure to comply with requirements under the FDCA or PHSA and other applicable
48
laws at any time during the product development process, approval process or after approval may subject an applicant and/or sponsor to a variety of administrative or judicial sanctions, including refusal by the FDA to approve pending applications, withdrawal of an approval, imposition of a clinical hold, issuance of warning letters and other types of letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement of profits, or civil or criminal investigations and penalties brought by the FDA and the Department of Justice or other governmental entities, including state agencies.
A drug candidate must be approved by the FDA through a new drug application, or NDA. A biologic candidate is licensed by the FDA through approval of a biologic license application, or BLA. An applicant seeking approval to market and distribute a new product in the United States must typically undertake the following:
•completion of preclinical laboratory tests, animal studies and formulation studies in compliance with the FDA’s good laboratory practice, or GLP, regulations;
•completion of the manufacture, under current Good Manufacturing Practices, or cGMP, conditions, of the drug substance and drug product that the sponsor intends to use in human clinical trials along with required analytical and stability testing;
•submission to the FDA of an IND, which must take effect before human clinical trials may begin;
•approval by an independent institutional review board, or IRB, representing each clinical trial site before each clinical trial may be initiated at that clinical site;
•performance of adequate and well-controlled human clinical trials in accordance with good clinical practices, or GCP, to establish the safety and efficacy of the proposed drug product for each indication for which the sponsor is seeking approval and the safety, potency and purity of a candidate biologic product for each indication for which the sponsor is seeking approval;
•preparation and submission to the FDA of an application requesting marketing approval for one or more proposed indications;
•review by an FDA advisory committee, where appropriate or if applicable;
•satisfactory completion of one or more FDA inspections of the manufacturing facility or facilities at which the product, or components thereof, are produced to assess compliance with cGMP requirements and to assure that the facilities, methods and controls are adequate to preserve the product’s identity, strength, quality and purity;
•satisfactory completion of FDA audits of clinical trial sites to assure compliance with GCPs and the integrity of the clinical data;
•payment of user fees and securing FDA approval of the application; and
•compliance with any post-approval requirements, including the potential requirement to implement a Risk Evaluation and Mitigation Strategy, or REMS, and the potential requirement to conduct post-approval studies.
Preclinical Studies
Before an applicant begins testing a drug or biologic with potential therapeutic value in humans, the product candidate must undergo preclinical testing. Preclinical studies include laboratory evaluation of product chemistry, toxicity and formulation, and the purity and stability of the substance, as well as in vitro and animal studies to assess the potential safety and activity of the product candidate for initial testing in humans and to establish a rationale for therapeutic use. The conduct of preclinical studies is subject to federal regulations and requirements, including GLP regulations.
The IND and IRB Processes
An IND is an exemption from the FDCA that allows an unapproved product to be shipped in interstate commerce for use in an investigational clinical trial and a request for FDA authorization to administer an investigational product to humans. Such authorization must be secured prior to interstate shipment and administration of any product candidate that is not the subject of an approved application. In support of a request for an IND, applicants must submit a protocol for each clinical trial
49
and any subsequent protocol amendments must be submitted to the FDA as part of the IND. In addition, the results of the preclinical tests, together with manufacturing information, analytical data and any available clinical data or literature and plans for clinical trials, among other things, are submitted to the FDA as part of an IND. The FDA requires a 30-day waiting period after the filing of each IND before clinical trials may begin. This waiting period is designed to allow the FDA to review the IND to determine whether human research subjects will be exposed to unreasonable health risks. At any time during this 30-day period, or thereafter, the FDA may raise concerns or questions about the conduct of the trials as outlined in the IND and impose a clinical hold or partial clinical hold. In this case, the IND sponsor and the FDA must resolve any outstanding concerns before clinical trials can begin or re-commence.
In addition to the foregoing IND requirements, an IRB or ethics committee representing each institution participating in the clinical trial must review and approve the plan for any clinical trial before it commences at that institution, and the IRB must conduct continuing review and re-approve the study at least annually. The IRB must review and approve, among other things, the study protocol and informed consent information to be provided to study subjects. An IRB must operate in compliance with FDA regulations. An IRB can suspend or terminate approval of a clinical trial at its institution, or an institution it represents, if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the product candidate has been associated with unexpected serious harm to patients.
Additionally, some trials are overseen by an independent group of qualified experts organized by the trial sponsor, known as a data safety monitoring board or committee, or DSMB. This group provides authorization as to whether or not a trial may move forward at designated check points based on certain available data from the study to which only the DSMB may access. Suspension or termination of development during any phase of clinical trials can occur if it is determined that the participants are being exposed to an unacceptable health risk. Other reasons for suspension or termination may be made by the sponsor based on evolving business objectives and/or competitive climate.
Information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health, or NIH, for public dissemination on its ClinicalTrials.gov website.
Human Clinical Trials in Support of an Application
Clinical trials involve the administration of an investigational product to human subjects under the supervision of qualified investigators in accordance with GCP requirements, which include, among other things, the requirement that all research subjects provide their informed consent in writing before their participation in any clinical trial. Clinical trials are conducted under written study protocols detailing, among other things, the inclusion and exclusion criteria, the objectives of the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated.
Human clinical trials are typically conducted in four sequential phases, which may overlap or be combined:
•Phase 1. The product candidate is initially introduced into a small number of healthy human subjects or, in certain indications, including those for which we are developing product candidates, patients with the target disease or condition and tested for safety, dosage tolerance, absorption, metabolism, distribution, excretion and, if possible, to gain an early indication of its effectiveness and to determine optimal dosage.
•Phase 2. The product candidate is administered to a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage. Phase 2a clinical trials tend to be smaller pilot studies for the purpose of demonstrating biological activity and clinical "proof of concept." Phase 2b studies tend to be larger studies focused on finding the optimal dosage and may be controlled.
•Phase 3. These clinical trials are commonly referred to as “pivotal” studies, which denotes a study that presents the data that the FDA or other relevant regulatory agency will use to determine whether or not to approve a product candidate. The product candidate is administered to an expanded patient population, generally at geographically dispersed clinical trial sites, in well-controlled clinical trials to generate enough data to statistically evaluate the efficacy and safety of the product for approval, identify adverse effects, establish the overall risk–benefit profile of the product and to provide adequate information for the labeling of the product.
•Phase 4. Post-approval studies may be required to be conducted after initial marketing approval. These studies are used to gain additional experience from the treatment of patients in the intended therapeutic indication.
50
Progress reports detailing the safety results of the clinical trials must be submitted at least annually to the FDA and more frequently if serious adverse events occur. In addition, IND safety reports must be submitted to the FDA for any of the following: serious and unexpected suspected adverse reactions; findings from other studies or animal or in vitro testing that suggest a significant risk to humans exposed to the product candidate; and any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. The FDA, the sponsor or the DSMB may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects are being exposed to an unacceptable health risk. The FDA will typically inspect one or more clinical sites to assure compliance with GCPs and the integrity of the clinical data submitted.
Expanded Access to an Investigational Drug for Treatment Use
Expanded access, sometimes called “compassionate use,” is the use of investigational new drug products outside of clinical trials to treat patients with serious or immediately life-threatening diseases or conditions when there are no comparable or satisfactory alternative treatment options. Expanded access allows a patient to obtain an investigational new drug when enrolling in a clinical trial for that drug is difficult or not feasible for the patient. FDA regulations allow access to investigational drugs under an IND by the sponsor or the treating physician for treatment purposes on a case-by-case basis in certain circumstances, subject to FDA approval. There is no obligation for a sponsor to make its drug products available for expanded access. In April 2020, we adopted an expanded access policy, which is, as required by the 21st Century Cures Act, or Cures Act, available on our website.
In addition, the Right to Try Act, signed into law in May 2018, provides a federal framework for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without needing FDA approval under the expanded access program. There is no obligation for a drug manufacturer to make its drug products available to eligible patients under the Right to Try Act.
Special Regulations and Guidance Governing Gene Therapy Products
The FDA has defined a gene therapy product as one that mediates its effects by transcription and/or translation of transferred genetic material and/or by integrating into the host genome and which is administered as nucleic acids, viruses, or genetically engineered microorganisms. The products may be used to modify cells in vivo or transferred to cells ex vivo prior to administration to the recipient. Within the FDA, the Center for Biologics Evaluation and Research, or CBER, regulates gene therapy products. Within CBER, the review of gene therapy and related products is consolidated in the Office of Tissues and Advanced Therapies (OTAT), and the FDA has established the Cellular, Tissue and Gene Therapies Advisory Committee to advise CBER on its reviews. The NIH, including its Novel and Exceptional Technology and Research Advisory Committee, or NExTRAC, also advises the FDA on gene therapy issues and other issues related to emerging biotechnologies. The FDA and the NIH have published guidance documents relating to the development and submission of gene therapy protocols.
The FDA has issued various guidance documents regarding gene therapies, including final guidance documents released in January 2020 relating to chemistry, manufacturing and controls information for gene therapy INDs, long-term follow-up after the administration of gene therapy products, gene therapies for rare diseases and gene therapies for retinal disorders. Although the FDA has indicated that these and other guidance documents it previously issued are not legally binding, we believe that our compliance with them is likely necessary to gain approval for any gene therapy product candidate we may develop. The guidance documents provide additional factors that the FDA will consider at each of the above stages of development and relate to, among other things, the proper preclinical assessment of gene therapies; the proper design of tests to measure product potency in support of an IND or BLA application; and measures to observe delayed adverse effects in subjects who have been exposed to investigational gene therapies when the risk of such effects is high. Further, the FDA usually recommends that sponsors observe subjects for potential gene therapy-related delayed adverse events for a 15-year period, including a minimum of five years of annual examinations followed by 10 years of annual queries, either in person or by questionnaire.
Until 2019, most gene therapy clinical trials required pre-review by the predecessor of NExTRAC before being submitted for approval by the IRBs and any local biosafety boards. In 2019, the NIH eliminated the pre-review process and going forward, the review of future gene therapy clinical trial protocols would be largely handled by IRBs. Furthermore, in 2019, the NIH removed from public access the Genetic Modification Clinical Research Information System (GeMCRIS) database, which previously contained substantial amounts of safety and other patient information regarding human gene therapy studies performed to date.
51
Review of a Product Candidate by the FDA
If clinical trials are successful, the next step in the development process is the preparation and submission to the FDA of an application for marketing approval. The application is the vehicle through which applicants formally propose that the FDA approve a new drug for marketing and sale in the United States for one or more indications. The application must contain a description of the manufacturing process and quality control methods, as well as results of preclinical tests, toxicology studies, clinical trials and proposed labeling, among other things. Every new product must be the subject of an approved application before it may be commercialized in the United States. Under federal law, the submission of most applications is subject to an application user fee, which for federal fiscal year 2021 is $2,875,842 for an application requiring clinical data. The sponsor of an approved application is also subject to an annual program fee, which for fiscal year 2021 is $336,432. Certain exceptions and waivers are available for some of these fees, such as an exception from the application fee for products with orphan designation and a waiver for certain small businesses.
Following submission of an application, the FDA conducts a preliminary review of an application generally within 60 calendar days of its receipt and strives to inform the sponsor by the 74th day after the FDA’s receipt of the submission to determine whether the application is sufficiently complete to permit substantive review. The FDA may request additional information rather than accept an application for filing. In this event, the application must be resubmitted with the additional information. The resubmitted application is also subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in depth substantive review. Under the Prescription Drug User Fee Act, or PDUFA, the FDA has agreed to specified performance goals and timelines in the review process of applications, which goals and timelines depend on the type of product candidate for which review is sought and whether the sponsor has applied for and received from the FDA any special review status for the particular product candidate allowing for expedited review. Special review status is available for certain products that are intended to address an unmet medical need in the treatment of a serious or life–threatening disease or condition under one of the following FDA-designations: fast track designation, breakthrough therapy designation, priority review designation and regenerative medicine advanced therapy designation. The review process and the PDUFA goal date may be extended by the FDA for three additional months to consider new information or clarification provided by the applicant to address an outstanding deficiency identified by the FDA following the original submission.
Before approving an application, the FDA typically will inspect the facility or facilities where the product is or will be manufactured, stored, packaged and tested. These pre–approval inspections may cover all facilities associated with an application submission, including component manufacturing (e.g., active pharmaceutical ingredients), finished product manufacturing, and control testing laboratories. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving an application, the FDA will typically inspect one or more clinical sites to assure compliance with GCP.
In addition, as a condition of approval, the FDA may require an applicant to develop a REMS. REMS use risk minimization strategies beyond the professional labeling to ensure that the benefits of the product outweigh the potential risks. To determine whether a REMS is needed, the FDA will consider the size of the population likely to use the product, seriousness of the disease, expected benefit of the product, expected duration of treatment, seriousness of known or potential adverse events, and whether the product is a New Molecular Entity.
The FDA is required to refer an application for a novel product candidate to an advisory committee or explain why such referral was not made. Typically, an advisory committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.
Under the Pediatric Research Equity Act, or PREA, an application or supplement thereto must contain data that are adequate to assess the safety and effectiveness of the product for the claimed indications in all relevant pediatric subpopulations, and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. With enactment of the Food and Drug Administration Safety and Innovation Act, or FDASIA, in 2012, sponsors must also submit pediatric study plans prior to the submission of the assessment data required under PREA. These plans are subject to FDA review before beginning the pediatric study. Product candidates that have received orphan designation are generally exempt from the requirements of PREA. In addition, a sponsor may apply for a waiver of the PREA requirements, which the FDA has indicated it will automatically grant for certain diseases that do not affect pediatric populations, including AMD.
52
The FDA’s Decision on an Application
On the basis of the FDA’s evaluation of the application and accompanying information, including the results of the inspections of the manufacturing facilities, the FDA may issue an approval letter or a complete response letter. An approval letter authorizes commercial marketing of the product with specific prescribing information for specific indications. A complete response letter generally outlines the deficiencies in the submission and may require substantial additional testing or information in order for the FDA to reconsider the application. If and when those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the application, the FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions in two or six months depending on the type of information included. Even with submission of this additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.
If the FDA approves a product, it may limit the approved indications for use of the product, require that contraindications, warnings or precautions be included in the product labeling, require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess the product’s safety after approval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution restrictions or other risk management mechanisms, including REMS, which can materially affect the potential market and profitability of the product. The FDA may prevent or limit further marketing of a product based on the results of post–market studies or surveillance programs.
Fast Track, Breakthrough Therapy, Priority Review and Regenerative Advanced Therapy Designations and Accelerated Approval; Rare Pediatric Disease Priority Review Voucher Program
The FDA is authorized to designate certain products for expedited review if they are intended to address an unmet medical need in the treatment of a serious or life–threatening disease or condition. These programs are fast track designation, breakthrough therapy designation, priority review designation and regenerative advanced therapy designation. The FDA may also approve certain products based on an accelerated basis.
Specifically, the FDA may designate a product for fast track review if it is intended, whether alone or in combination with one or more other products, for the treatment of a serious or life–threatening disease or condition, and if the product demonstrates the potential to address unmet medical needs for such a disease or condition. For fast track products, sponsors may have greater interactions with the FDA and the FDA may initiate review of sections of a fast track product’s application before the application is complete. This rolling review may be available if the FDA determines, after preliminary evaluation of clinical data submitted by the sponsor, that a fast track product may be effective. The sponsor must also provide, and the FDA must approve, a schedule for the submission of the remaining information. However, the FDA’s time period goal for reviewing a fast track application does not begin until the last section of the application is submitted. In addition, the fast track designation may be withdrawn by the FDA if the FDA believes that the designation is no longer supported by data emerging in the clinical trial process. In April 2020, the FDA granted fast track designation to Zimura for the treatment of GA secondary to dry AMD.
FDASIA established a new regulatory scheme allowing for expedited review of products designated as “breakthrough therapies.” A product may be designated as a breakthrough therapy if it is intended, either alone or in combination with one or more other products, to treat a serious or life–threatening disease or condition and preliminary clinical evidence indicates that the product may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. The FDA may take certain actions with respect to breakthrough therapies, including holding meetings with the sponsor throughout the development process; providing timely advice to the product sponsor regarding development and approval; involving more senior staff in the review process; assigning a cross–disciplinary project lead for the review team; and taking other steps to design the clinical trials in an efficient manner.
The FDA may designate a product for priority review if it is a product that treats a serious condition and, if approved, would provide a significant improvement in safety or effectiveness. The FDA determines, on a case by case basis, whether the proposed product represents a significant improvement when compared with other available therapies. Significant improvement may be illustrated by evidence of increased effectiveness in the treatment of a condition, elimination or substantial reduction of a treatment–limiting product reaction, documented enhancement of patient compliance that may lead to improvement in serious outcomes, and evidence of safety and effectiveness in a new subpopulation. A priority designation is intended to direct overall attention and resources to the evaluation of such applications, and to shorten the FDA’s goal for taking action on a marketing application from ten months to six months.
With passage of the Cures Act, Congress authorized the FDA to accelerate review and approval of products designated as regenerative advanced therapies. A product is eligible for this designation if it is a regenerative medicine therapy that is
53
intended to treat, modify, reverse or cure a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the product candidate has the potential to address unmet medical needs for such disease or condition. The benefits of a regenerative advanced therapy designation include early interactions with the FDA to expedite development and review, benefits available to breakthrough therapies, and potential eligibility for priority review and accelerated approval based on surrogate or intermediate endpoints.
The FDA may grant accelerated approval to a product for a serious or life–threatening condition that provides meaningful therapeutic advantage to patients over existing treatments based upon a determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit. The FDA may also grant accelerated approval for such a condition when the product has an effect on an intermediate clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality and that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. Products granted accelerated approval must meet the same statutory standards for safety and effectiveness as those granted traditional approval.
Finally, the FDA may award priority review vouchers to sponsors of rare pediatric disease product applications that meet certain criteria. A rare pediatric disease is a rare disease where the disease is serious or life-threatening with the serious or life-threatening manifestations primarily affecting individuals from age zero to 18. A sponsor who receives approval for a drug or biologic for a rare pediatric disease may qualify for a priority review voucher, which the sponsor may redeem to receive priority review of a subsequent marketing application for a different product. In lieu of using the voucher for one of its own product candidates, a sponsor may sell that voucher for use by a third party. Current prices for these vouchers range in the hundreds of millions of dollars. The current rare pediatric disease priority review voucher program, which was previously scheduled to expire in October 2020, will expire in September 2024, after Congress recently renewed the program, although a drug designated as a rare pediatric disease treatment by September 2024 can still receive a priority review voucher but no later than September 2026.
Post-Approval Requirements
Products manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, advertising and promotion and reporting of adverse experiences with the product. After approval, most changes to the approved product, such as adding new indications or other label changes, or changing the manufacturing process for the approved product, are subject to additional testing and/or FDA review and approval.
In addition, manufacturers and other entities involved in the manufacture and distribution of approved products are required to register their establishments with the FDA and state agencies, and are subject to periodic unannounced inspections by the FDA and these state agencies for compliance with cGMP requirements. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting and documentation requirements upon the sponsor and any third–party manufacturers that the sponsor may decide to use. Accordingly, sponsors and manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. Further, the FDA will conduct laboratory research related to the safety, purity, potency and effectiveness of pharmaceutical products.
Once an approval is granted, the FDA may restrict, suspend or withdraw the approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical trials to assess new safety risks; or imposition of distribution or other restrictions under a REMS program. Other potential consequences include, among other things:
•fines, warning letters or holds on post-approval clinical trials;
•product seizure or detention, or refusal to permit the import or export of products; or
•injunctions or the imposition of civil or criminal penalties.
The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Products may be promoted only for the approved indications and in accordance with the provisions of the approved label. Although health care providers may prescribe products for off-label uses in their professional judgment, drug manufacturers are prohibited from soliciting, encouraging or promoting unapproved uses of a product.
54
Generic Drugs and Exclusivity
Under the Hatch-Waxman Amendments to the FDCA, the FDA is authorized to approve generic drugs that are shown to contain the same active ingredients as, and is bioequivalent to, drugs previously approved by the FDA pursuant to NDAs, which are also known as reference listed drugs, or RLDs. To obtain approval of a generic drug, an applicant must submit an abbreviated new drug application, or ANDA, to the FDA. An ANDA applicant does not generally rely on its own preclinical or clinical data to demonstrate safety and effectiveness but instead can rely on preclinical and clinical testing previously conducted by the sponsor of the RLD. The ANDA applicant must show that the generic version is identical to the RLD with respect to a number of factors, including the active ingredient, and that the generic version is "bioequivalent" to the RLD. Physicians, pharmacists and third-party payors generally consider an approved generic drug to be fully substitutable for the RLD.
Sponsors of RLDs are required to list in the FDA's Orange Bank each patent with claims covering the RLD or approved methods of using the RLD. An ANDA applicant is required to certify to the FDA concerning any such patents, which may be a certification that the listed patent is invalid, unenforceable or will not be infringed by the new product, which is known as a Paragraph IV certification. An ANDA applicant that makes a Paragraph IV certification must notify the sponsor of the RLD, who may then initiate a patent infringement lawsuit in response to the notice of Paragraph IV certification. The filing of a lawsuit within 45 days of receipt of a Paragraph IV certification notice prevents the FDA from approving the ANDA until the earliest of 30 months after receipt of the Paragraph IV certification, expiration of the patent or a decision in the infringement case that is favorable to the ANDA applicant.
Market and data exclusivity provisions under the FDCA can delay the submission or the approval of certain drug applications for competing products, including generic drugs. The FDCA provides a five-year period of non-patent data exclusivity within the United States to the first applicant to gain approval of an NDA for a New Chemical Entity. A drug is a New Chemical Entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule responsible for the pharmacological activity of the drug substance. During the exclusivity period, the FDA may not accept for review an ANDA or an NDA under Section 505(b)(2) of the FDCA, or an 505(b)(2) NDA, submitted by another company that references the previously approved drug. However, an ANDA or 505(b)(2) NDA may be submitted after four years if it contains a Paragraph IV certification.
The FDCA also provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA, or supplement to an existing NDA or 505(b)(2) NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant, are deemed by the FDA to be essential to the approval of the application or supplement. Three-year exclusivity may be awarded for changes to a previously approved drug product, such as new indications, dosages, strengths or dosage forms of an existing drug. This three-year exclusivity covers only the conditions of use associated with the new clinical investigations and, as a general matter, does not prohibit the FDA from approving ANDAs or 505(b)(2) NDAs for generic versions of the original, unmodified drug product. The five-year and three-year exclusivities will not delay the submission or approval of a full NDA; however, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.
Biosimilars and Exclusivity
The Patient Protection and Affordable Care Act, or ACA, included a subtitle called the Biologics Price Competition and Innovation Act of 2009, or BPCIA. The BPCIA established a regulatory scheme authorizing the FDA to approve biosimilars and interchangeable biosimilars. A biosimilar is a biological product that is highly similar to an existing FDA-licensed "reference product." As of January 1, 2021, the FDA had approved 29 biosimilar products for use in the United States. No interchangeable biosimilars, as described below, have been approved as of January 1, 2021. The FDA has issued several guidance documents outlining an approach to the review and approval of biosimilars.
Under the BPCIA, a manufacturer may submit an application for licensure of a biologic product that is biosimilar to a reference product. In order for the FDA to approve a biosimilar product, it must find that there are no clinically meaningful differences between the reference product and proposed biosimilar product in terms of safety, purity and potency. For the FDA to approve a biosimilar product as "interchangeable" with a reference product, the agency must find that the biosimilar product can be expected to produce the same clinical results as the reference product, and for products administered multiple times, that the biologic and the reference biologic may be switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic.
Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date of approval of the reference product. The FDA may not approve a biosimilar product until 12 years from the date on which the reference product was approved. Even if a product is considered to be a reference product eligible for exclusivity,
55
another company could market a competing version of that product if the FDA approves a full BLA for such product containing the sponsor’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity and potency of their product. The BPCIA also created certain exclusivity periods for biosimilars approved as interchangeable products. Since the passage of the BPCIA, many states have passed laws or amendments to laws, including laws governing pharmacy practices, which are state-regulated, to regulate the use of biosimilars.
Patent Term Extension
A patent claiming a new drug product, its method of use or its method of manufacture may be eligible for a limited patent term extension, also known as patent term restoration, under the Hatch-Waxman Amendments, which permits a patent restoration of up to five years for patent term lost during product development and FDA regulatory review. Patent term extension is generally available only for drug products whose active ingredient has not previously been approved by the FDA. The restoration period granted is typically one-half the time between the effective date of an IND and the submission date of a marketing approval application, plus the time between the submission date of a marketing approval application and the ultimate approval date. Patent term extension cannot be used to extend the remaining term of a patent past a total of 14 years from the product’s approval date. Only one patent applicable to an approved drug product is eligible for the extension, and the application for the extension must be submitted prior to the expiration of the patent in question. A patent that covers multiple drugs for which approval is sought can only be extended in connection with one of the approvals. The United States Patent and Trademark Office (USPTO) reviews and approves the application for any patent term extension in consultation with the FDA.
Orphan Drug Designation and Exclusivity
Under the Orphan Drug Act, the FDA may designate a product as an “orphan drug” if it is intended to treat a rare disease or condition, generally meaning that it affects fewer than 200,000 individuals in the United States, or more in cases in which there is no reasonable expectation that the cost of developing and making a product available in the United States for treatment of the disease or condition will be recovered from sales of the product. A company must request orphan drug designation before submitting an application for the product and the rare disease or condition. If the request is granted, the FDA will disclose the identity of the therapeutic agent and its potential use. Orphan drug designation does not shorten the PDUFA goal dates for the regulatory review and approval process, although it does convey certain advantages such as tax benefits and exemption from the PDUFA application fee.
If a product with orphan designation receives the first FDA approval for the disease or condition for which it has such designation or for a select indication or use within the rare disease or condition for which it was designated, the product generally will receive orphan drug exclusivity. Orphan drug exclusivity means that the FDA may not approve another sponsor’s marketing application for the same product for the same indication for seven years, except in certain limited circumstances. Orphan exclusivity does not block the approval of a different product for the same rare disease or condition, nor does it block the approval of the same product for different indications. In particular, the concept of what constitutes the "same product" for purposes of orphan drug exclusivity remains in flux in the context of gene therapies, and the FDA has issued recent draft guidance suggesting that it would not consider two gene therapy products to be different products solely based on minor differences in the transgenes or vectors. If a product designated as an orphan drug ultimately receives marketing approval for an indication broader than what was designated in its orphan drug application, it may not be entitled to exclusivity.
Orphan drug exclusivity will not bar approval of another product under certain circumstances, including if a subsequent product for the same indication is shown to be clinically superior to the approved product on the basis of greater efficacy or safety or provides a major contribution to patient care, or if the company with orphan drug exclusivity is not able to meet market demand.
Pediatric Exclusivity
Pediatric exclusivity is another type of non-patent exclusivity in the United States and, if granted, provides for an additional six months of marketing protection to the term of any existing regulatory exclusivity or patent protection, including the non-patent and orphan drug exclusivity. This six-month exclusivity may be granted if an application sponsor submits pediatric data that fairly respond to a written request from the FDA for such data. The data do not need to show that the product is effective in the pediatric population studied; rather, if the clinical trial is deemed to fairly respond to the FDA’s request, the additional protection is granted. If reports of requested pediatric studies are submitted to and accepted by the FDA within the statutory time limits, whatever statutory or regulatory periods of exclusivity or patent protection covering the product are extended by six months. This is not a patent term extension, but it effectively extends the regulatory period during which the FDA cannot approve an ANDA or 505(b)(2) NDA that references the product. With regard to patents, the six-month pediatric exclusivity period will not attach to any patents for which an ANDA or 505(b)(2) applicant submitted a paragraph IV
56
certification, unless the NDA sponsor or patent owner first obtains a court determination that the patent is valid and infringed by the proposed ANDA or 505(b)(2) product.
Review and Approval of Products in Europe and other Foreign Jurisdictions
In addition to regulations in the United States, a manufacturer is subject to a variety of regulations in foreign jurisdictions to the extent it chooses to conduct clinical trials or sell any products in those foreign countries. Even if a manufacturer obtains FDA approval of a product, it must still obtain the requisite approvals from regulatory authorities in foreign countries before beginning clinical trials or marketing the product in those countries. To obtain regulatory approval of an investigational product in the European Union, a manufacturer must submit a marketing authorization application, or MAA, to the EMA. For other countries outside of the European Union, such as countries in Latin America or Asia, the requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, clinical trials are to be conducted in accordance with GCP and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.
Clinical Trial Approval in the European Union
Under the currently applicable Clinical Trials Directive 2001/20/EC and the Directive 2005/28/EC on Good Clinical Practice, an applicant must obtain prior approval from the competent national authority of the European Union Member State, or the EU Member State, in which the clinical trial is to be conducted. If the clinical trial is conducted in different EU Member States, the competent authorities in each of these EU Member States must provide their approval for the conduct of the clinical trial. Furthermore, the applicant may only start a clinical trial at a specific study site after the applicable ethics committee has issued a favorable opinion.
In April 2014, the European Union adopted a new Clinical Trials Regulation (EU) No 536/2014, which is set to replace the current Clinical Trials Directive 2001/20/EC. The new regulation aims at simplifying and streamlining the approval of clinical trials in the European Union. Under the new coordinated procedure for the approval of clinical trials, the sponsor of a clinical trial to be conducted in more than one EU Member State will only be required to submit a single application for approval of a clinical trial to a reporting EU Member State. The Clinical Trials Regulation also aims to streamline and simplify the rules on safety reporting for clinical trials. The Clinical Trials Regulation is expected to become effective in December 2021, in conjunction with the expected going live date of a new clinical trials portal and database being developed for the new regulatory framework.
Marketing Authorization
In the European Union, marketing authorizations for medicinal products may be obtained through different procedures founded on the same basic regulatory process. A marketing authorization may be granted only to an applicant established in the European Union. As in the United States, marketing authorization holders and manufacturers of approved medicinal products are subject to comprehensive regulatory oversight by the EMA and the competent authorities of the individual EU Member States both before and after grant of marketing authorizations.
Centralized Procedure. The centralized procedure provides for the grant of a single marketing authorization by the European Commission that is valid across the European Economic Area, i.e. the European Union as well as Iceland, Liechtenstein and Norway. The centralized procedure is compulsory for medicinal products produced by certain biotechnological processes, products designated as orphan medicinal products, and products with a new active substance indicated for the treatment of certain diseases. It is optional for those products that are highly innovative or for which a centralized process is not in the interest of patients. Manufacturers must demonstrate the quality, safety, and efficacy of their products to the EMA, which provides an opinion regarding the MAA. The European Commission grants or refuses marketing authorization in light of the opinion delivered by the EMA.
Specialized Procedures for Gene Therapies. The grant of marketing authorization in the European Union for gene therapy products is governed by Regulation 1394/2007/EC on advanced therapy medicinal products, read in combination with Directive 2001/83/EC of the European Parliament and of the Council, commonly known as the Community code on medicinal products for human use. Regulation 1394/2007/EC includes specific rules concerning the authorization, supervision, and pharmacovigilance of gene therapy medicinal products. All advanced therapy medicinal products are approved centrally through the EMA. The EMA's Committee for Advanced Therapies reviews and provides an opinion regarding each advanced therapy MAA for potential final approval by the European Commission.
57
Decentralized Procedure. The decentralized procedure provides for approval by one or more other concerned EU Member States of an assessment of an MAA conducted by one EU Member State, known as the reference EU Member State. In accordance with this procedure, an applicant submits an MAA to the reference EU Member State and the concerned EU Member States. This application is identical to the application that would be submitted to the EMA for authorization through the centralized procedure. Following receipt of a valid application, the reference EU Member State prepares a draft assessment and drafts of the related materials. The resulting assessment report is submitted to the concerned EU Member States which must decide whether to approve the assessment report and related materials.
If a concerned EU Member State cannot approve the assessment report and related materials due to concerns relating to a potential serious risk to public health, disputed elements may be referred to the European Commission, whose decision is binding on all EU Member States. Authorization in accordance with the decentralized procedure will result in authorization of the medicinal product only in the reference EU Member State and in the other concerned EU Member States.
Mutual Recognition Procedure. In accordance with the mutual recognition procedure, the sponsor applies for national marketing authorization in one EU Member State. Upon receipt of this authorization the sponsor can then seek the recognition of this authorization by other EU Member States.
Periods of Authorization and Renewals in the European Union
A marketing authorization is valid for five years, in principle, and it may be renewed after five years on the basis of a reevaluation of the risk-benefit balance by the EMA or by the relevant EU Member State. To seek renewal, at least six months prior to expiration of the marketing authorization, the holder must provide the EMA or the EU Member State with a consolidated version of the file detailing the continued quality, safety and efficacy of the product, including all variations introduced since the marketing authorization was granted. Once renewed, the marketing authorization is valid for an unlimited period, unless the European Commission or the relevant competent authority of the EU Member State decides, on justified grounds relating to pharmacovigilance, to proceed with one additional five-year renewal period. Any marketing authorization that is not followed by the marketing of the medicinal product on the European Union market, in the case of the centralized procedure, or in the market of the EU Member State which delivered the marketing authorization, in the case of the decentralized procedure, within three years after authorization ceases to be valid.
Patent Term Extensions in the European Union and Other Jurisdictions
The European Union also provides for patent term extension through Supplementary Protection Certificates, or SPCs. The rules and requirements for obtaining a SPC are similar to those in the United States. An SPC may extend the term of a patent for up to five years after its originally scheduled expiration date and can provide up to a maximum of fifteen years of marketing exclusivity for a drug. These periods can be extended for six additional months if pediatric exclusivity is obtained, which is described in detail below. Although SPCs are available throughout the European Union, sponsors must apply on a country-by-country basis. Similar patent term extension rights exist in certain other foreign jurisdictions outside the European Union.
Regulatory Data Exclusivity in the European Union
In the European Union, innovative medicinal products approved on the basis of a complete independent data package qualify for eight years of data exclusivity upon marketing authorization and an additional two years of market exclusivity. Data exclusivity prevents applicants for authorization of generics of these innovative products from referencing the innovator’s data in a generic (abridged) application for a period of eight years. During an additional two-year period of market exclusivity, a generic MAA can be submitted and authorized, and the innovator’s data may be referenced, but no generic medicinal product can be placed on the European Union market until the expiration of the market exclusivity. The overall ten-year period will be extended to a maximum of 11 years if, during the first eight years of those ten years, the marketing authorization holder obtains an authorization for one or more new therapeutic indications that are shown, during the scientific evaluation prior to authorization, to bring a significant clinical benefit in comparison with existing therapies. Even if a compound is considered to be an innovative medicinal product so that the innovator gains the additional prescribed period of marketing exclusivity, another company nevertheless could also market another version of the product if such company obtained marketing authorization based on an MAA with a complete independent data package of pharmaceutical tests, preclinical tests and clinical trials.
Orphan Drug Designation and Exclusivity in the European Union
Regulation (EC) No 141/2000 and Regulation (EC) No. 847/2000 provide that a product can be designated as an orphan medicinal product by the European Commission if its sponsor can establish that the product is intended for the diagnosis, prevention or treatment of: (1) a life-threatening or chronically debilitating condition affecting not more than five in ten thousand persons in the European Union when the application is made, or (2) a life-threatening, seriously debilitating or
58
serious and chronic condition in the European Union and that without incentives the medicinal product is unlikely to be developed. For either of these conditions, the applicant must demonstrate that there exists no satisfactory method of diagnosis, prevention or treatment of the condition in question that has been authorized in the European Union or, if such method exists, the medicinal product will be of significant benefit to those affected by that condition.
Once authorized, orphan medicinal products are entitled to ten years of market exclusivity in all EU Member States and, in addition, a range of other benefits during the development and regulatory review process, including scientific assistance for study protocols, authorization through the centralized marketing authorization procedure and a reduction or elimination of registration and marketing authorization fees. The market exclusivity period can be extended by two years following completion of an agreed upon pediatric investigation plan. However, marketing authorization may be granted to a similar medicinal product with the same orphan indication during the ten year period with the consent of the marketing authorization holder for the original orphan medicinal product or if the manufacturer of the original orphan medicinal product is unable to supply sufficient quantities. Marketing authorization may also be granted to a similar medicinal product with the same orphan indication if the new product is safer, more effective or otherwise clinically superior to the original orphan medicinal product. The period of market exclusivity may, in addition, be reduced to six years if it can be demonstrated on the basis of available evidence that the original orphan medicinal product is sufficiently profitable to not justify maintenance of market exclusivity.
Pediatric Studies and Exclusivity
Before obtaining a marketing authorization in the European Union, applicants must demonstrate compliance with all measures included in an EMA-approved Pediatric Investigation Plan, or PIP, approved by the Pediatric Committee of the EMA, or PDCO, covering all subsets of the pediatric population, unless the EMA has granted a product-specific waiver, a class waiver, or a deferral for one or more of the measures included in the PIP. This requirement also applies when a company wants to add a new indication, pharmaceutical form or route of administration for a medicine that is already authorized. The PDCO may grant deferrals for some medicines, allowing a company to delay development of the medicine for children until there is enough information to demonstrate its effectiveness and safety in adults. The PDCO may also grant waivers when development of a medicine for children is not needed or is not appropriate, such as for diseases that only affect the elderly population. Before an MAA can be filed, or an existing marketing authorization can be amended, the EMA must determine that the applicant actually complied with the agreed studies and measures listed in each relevant PIP. If an applicant obtains a marketing authorization in all EU Member States, or a marketing authorization granted via the centralized procedure by the European Commission, and the study results for the pediatric population are included in the product information, even when negative, the medicine is then eligible for an additional six-month period of qualifying patent protection through extension of the term of the SPC.
Brexit and the Regulatory Framework in the United Kingdom
On January 31, 2020, the United Kingdom left the European Union in an event called "Brexit". As of January 1, 2021, European Union laws and regulations generally became inapplicable in the United Kingdom. In December 2020, the United Kingdom and the European Union entered into a long-term trade agreement that governs their future economic relations. Since the pre-existing regulatory framework for pharmaceutical products in the United Kingdom is derived from European Union directives and regulations, which the United Kingdom could abandon or modify in the future, subject to the terms of the recently concluded long-term trade agreement, Brexit could materially impact the future regulatory regime for pharmaceutical products in the United Kingdom. We are continuing to analyze how Brexit and the recently concluded trade agreement will affect the future regulatory regime for pharmaceutical products in the United Kingdom.
Pharmaceutical Insurance Coverage, Pricing and Reimbursement
In the United States and markets in many other countries, patients who are prescribed treatments for their conditions and providers performing the prescribed services generally rely on third-party payors to reimburse all or part of the associated healthcare costs. Significant uncertainty exists as to the coverage and reimbursement status of products approved by the FDA and other government authorities. Thus, even if a product candidate is approved, sales of the product will depend, in part, on the extent to which third-party payors, including government health programs in the United States such as Medicare and Medicaid, commercial health insurers and managed care organizations, provide coverage, and establish adequate reimbursement levels, for the product. Third-party payors are increasingly challenging the prices charged, examining the medical necessity, and reviewing the cost-effectiveness of medical products and services and imposing controls to manage costs. Third-party payors may limit coverage for a particular indication to specific products on an approved list, also known as a formulary, which might not include all of the approved products for such indication.
59
In order to secure coverage and reimbursement for any product that might be approved for sale, a company may need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the studies required to obtain FDA or other comparable marketing approvals. Nonetheless, product candidates may not be considered medically necessary or cost effective by the payors. A payor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will be approved. Further, one payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage and reimbursement for the product, and the level of coverage and reimbursement can differ significantly from payor to payor. Moreover, coverage policies and third-party reimbursement rates may change at any time.
The containment of healthcare costs also has become a priority of federal, state and foreign governments and the prices of pharmaceutical products have been a focus in this effort. Governments have shown significant interest in implementing cost-containment programs, including rebate programs, price controls, restrictions on reimbursement and requirements for substitution of generic products. Efforts to control drug pricing have garnered bipartisan support in the U.S. Congress. The Trump Administration issued a number of executive orders and during the Trump Administration, various U.S. government agencies, including the FDA and the Center for Medicare & Medicaid Services, or CMS, proposed a number of rules intended to curb drug prices.
The Biden Administration has frozen certain of the Trump Administration’s measures to reform drug prices, pending further review. It remains to be seen how the Biden Administration will address this issue. The Biden Administration may pursue reference pricing policies, which is a regime that sets the price of certain drugs by reference to the average price of these drugs in other developed countries, or may seek to amend existing law that currently bans Medicare from negotiating lower prices with drug manufacturers.
At the state level, individual states are increasingly passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on access to certain products, and marketing cost disclosure and transparency measures, and, in some cases, measures designed to encourage importation from other countries and bulk purchasing. In addition, regional health care authorities and individual hospitals are increasingly using bidding procedures to determine which pharmaceutical products and which suppliers will be included in their prescription drug and other health care programs. These measures could reduce the ultimate demand for our products, if and once approved, or put pressure on our product pricing.
Outside the United States, ensuring adequate coverage and payment for a product also involves challenges. Pricing of prescription pharmaceuticals is subject to governmental control in many countries. Pricing negotiations with governmental authorities can extend well beyond the receipt of regulatory marketing approval for a product and may require a clinical trial that compares the cost effectiveness of a product to other available therapies. The conduct of such a clinical trial could be expensive and result in delays in commercialization.
In the European Union, pricing and reimbursement schemes vary widely from country to country. Some countries provide that products may be marketed only after a reimbursement price has been agreed. Some countries may require the completion of additional cost effectiveness clinical studies. EU Member States may approve a specific price for a product or any of them may instead adopt a system of direct or indirect controls on the profitability of the company placing the product on the market. Other member states allow companies to fix their own prices for products, but monitor and control prescription volumes and issue guidance to physicians to limit prescriptions. Over the past decade, many EU Member States have increased the amount of discounts required on pharmaceuticals and these efforts could continue as countries attempt to manage healthcare expenditures, especially in light of the severe fiscal and debt crises experienced by many countries in the European Union over the past decade. Reference pricing used by various EU Member States, and parallel trade, i.e., arbitrage between low-priced and high-priced member states, can further reduce prices.
In addition to initiatives specifically directed at lowering or containing prescription drug prices, legislative action in the United States at the national level has resulted in reduced funding levels for Medicare. For example, the Budget Control Act of 2011 led to aggregate reductions in Medicare payments to providers of up to 2% per fiscal year from 2013 through 2024, and the American Taxpayer Relief Act of 2012 reduced Medicare payments to several types of providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. Any reduction in healthcare, including Medicare, funding may affect the prices we may obtain for any of our product candidates for which we may obtain regulatory approval or the frequency with which any such product candidate is prescribed or used.
Moreover, the number of individuals covered by health insurance has a direct impact on the potential market for our product candidates, if approved. The ACA, passed in 2010, included the "individual mandate," which required most Americans to carry a minimal level of health insurance. Individuals who did not obtain required coverage were subject to a penalty. The
60
individual mandate was repealed as part of the Tax Cuts and Jobs Act of 2017, or TCJA, with the repeal becoming effective on January 1, 2019. According to the Congressional Budget Office, the repeal of the individual mandate will cause 13 million fewer Americans to be insured in 2027 and premiums in insurance markets may rise. In addition, the Trump Administration took a number of executive actions to undermine the ACA and there are current lawsuits pending regarding the ACA, including one being decided by the U.S. Supreme Court in its current term. We expect additional lawsuits may be filed.
Despite those developments, we expect the new 117th Congress and the Biden Administration to support and expand on the ACA. For example, on January 28, 2021, President Biden issued an executive order directing federal agencies to review all existing regulations, policies and a variety of other guidance that limit Americans’ access to high-quality healthcare and to
consider actions that will protect and strengthen Medicaid, the ACA and, more generally, access to affordable healthcare for Americans. Under this order, federal agencies are to advance President Biden’s overall access policy and make determinations as to whether additional actions are necessary. Specifically, the agencies must examine, among other things, policies that undermine protections for people with pre-existing conditions, including complications related to COVID-19, and policies that undermine the health insurance marketplace or other markets for health insurance.
Healthcare Law and Regulation
Healthcare providers and third-party payors play a primary role in the recommendation and prescription of products that are granted marketing approval. Arrangements with providers, consultants, third-party payors and customers are subject to broadly applicable fraud and abuse, anti-kickback, false claims, reporting of payments to physicians and patient privacy laws and regulations and other healthcare laws and regulations that may constrain business and/or financial arrangements. Restrictions under applicable federal and state healthcare laws and regulations include the following:
•the federal Anti-Kickback Statute, which prohibits, among other things, persons and entities from knowingly and willfully soliciting, offering, paying, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made, in whole or in part, under a federal healthcare program such as Medicare and Medicaid;
•federal civil and criminal false claims laws, including the civil False Claims Act, and civil monetary penalties laws, which prohibit individuals or entities from, among other things, knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false, fictitious or fraudulent or knowingly making, using or causing to made or used a false record or statement to avoid, decrease or conceal an obligation to pay money to the federal government;
•the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which, among other things, prohibits knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters;
•HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, and their respective implementing regulations, which impose obligations, including mandatory contractual terms, relating to safeguarding the privacy, security and transmission of individually identifiable health information by certain covered entities and their business associates;
•the federal false statements statute, which prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services;
•the federal Foreign Corrupt Practices Act, which, among other things, prohibits providing or offering to provide money or anything of value to a foreign government body, government official, or political candidate for the improper purpose of obtaining or keeping business;
•federal transparency requirements such as the federal Physician Payments Sunshine Act, created under the ACA, which requires certain manufacturers of drugs, devices, biologics and medical supplies to report annually to CMS information related to payments and other transfers of value made by that entity to physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members; and
61
•analogous state and foreign laws and regulations, such as state anti–kickback and false claims laws, which may apply to healthcare items or services that are reimbursed by private insurers.
Some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government in addition to requiring manufacturers to report information related to payments to physicians and other health care providers or marketing expenditures. State and foreign laws, such as the European Union's General Data Protection Regulation, also govern the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Item 1A. Risk Factors.
The following risk factors and other information included in this Annual Report on Form 10-K should be carefully considered. The risks and uncertainties described below are not the only risks and uncertainties we face. Additional risks and uncertainties not presently known to us or that we presently deem less significant may also impair our business operations. Please see page 1 of this Annual Report on Form 10-K for a discussion of some of the forward-looking statements that are qualified by these risk factors. If any of the following risks occur, our business, financial condition, results of operations and future growth prospects could be materially and adversely affected.
Risks Related to Our Business Plan, Financial Position and Need for Additional Capital
We are a development-stage company without any commercial products. The value of our company, therefore, is highly dependent on the success of our research and development efforts and the amount of our available cash. Our research and development programs, which are focused on novel therapies and technologies, carry significant scientific and other risks. If any of these programs are not successful, the value of your investment may decline.
We are a development-stage company without any approved products. Our growth prospects and the future value of our company are highly dependent on the progress of our research and development programs, including our ongoing and any future clinical trials for Zimura, our preclinical development programs for IC-100, IC-200 and IC-500, and our collaborative gene therapy sponsored research programs. Drug development is a highly uncertain undertaking and carries significant scientific and other risks.
We may encounter unforeseen difficulties, complications, delays, expenses and other known and unknown factors. We may never be successful in developing or commercializing any of our product candidates or other programs. There is a high rate of failure in pharmaceutical research and development. Even if we have promising preclinical or clinical candidates, their development could fail at any time. Our failure could be due to unexpected scientific, safety or efficacy issues with our product candidates and other programs, invalid hypotheses regarding the molecular targets and mechanisms of action we choose to pursue or unexpected delays in our research and development programs resulting from applying the wrong criteria or experimental systems and procedures to our programs or lack of experience or other factors, including disruptions resulting from the COVID-19 pandemic, with the possible result that none of our product candidates or other programs result in the development of marketable products. We have not yet demonstrated our ability to successfully complete the development of a pharmaceutical product, including completion of large-scale, pivotal clinical trials with safety and efficacy data sufficient to
62
obtain marketing approval or activities necessary to apply for and obtain marketing approval, including the qualification of a commercial manufacturer through a pre-approval inspection with regulatory authorities. If successful in developing and obtaining marketing approval of one of our product candidates, we would need to transition from a company with a product development focus to a company capable of commercializing pharmaceutical products. We may not be successful in such a transition, as our company has never conducted the sales, marketing and distribution activities necessary for successful product commercialization.
Because the value of our company is largely based on the prospects for our research and development programs and their potential to result in therapies capable of achieving marketing approval and generating future revenues, any failure, delay or setback for these programs will likely have a negative impact on the value of your investment. In addition, because a number of our product candidates are in the preclinical stage, even if we are successful in advancing the research and development of those product candidates, the value of our common stock may not rise in a meaningful way, which could affect our ability to raise additional finances. As we continue to invest in our research and development programs to generate data to support further development or applications to obtain marketing approval for commercialization, the amount of our available cash will continue to decline until we raise additional finances.
We have a history of significant operating losses. We expect to continue to incur losses until such time, if ever, that we successfully commercialize our product candidates and may never achieve or maintain profitability.
Since inception, we have experienced significant cash outflows in funding our operations. To date, we have not generated any revenues from commercial product sales and have financed our operations primarily through private placements of our common stock and preferred stock, venture debt borrowings, funds received under our prior Fovista royalty purchase and sale agreement with Novo Holdings A/S, our initial public offering, which we closed in September 2013, funds we received under our prior Fovista licensing and commercialization agreement with Novartis Pharma AG, funds we received in connection with our acquisition of Inception 4 in October 2018, and our follow-on public offerings, which we closed in February 2014, December 2019 and June 2020. As of December 31, 2020, we had an accumulated deficit of $565.1 million. Our net loss was $84.5 million for the twelve months ended December 31, 2020 and we expect to continue to incur significant operating losses for the foreseeable future.
Zimura is in clinical development, our gene therapy product candidates IC-100 and IC-200, and IC-500, the selected product candidate from our HtrA1 inhibitor program, are each in preclinical development, and we are funding multiple ongoing collaborative gene therapy sponsored research programs. We expect our research and development expenses to increase as we pursue these programs as currently planned. We could incur additional research and development expenses if we modify or further expand the scope of our clinical trials, including if we develop Zimura for additional indications, preclinical development programs or collaborative gene therapy sponsored research programs, or if we in-license or acquire, and undertake development of, additional product candidates and technologies, including any promising product candidates that emerge from our collaborative gene therapy sponsored research programs. We could also incur additional research and development expenses if, for example, we are required by the FDA, the EMA, or regulatory authorities in other jurisdictions to perform clinical trials and nonclinical or other studies in addition to those we currently expect to conduct. If we experience delays or disruptions to our research and development programs, including delays in patient enrollment or issues with patient retention or patients missing scheduled visits and treatments, if we experience issues with our preclinical development programs, such as unfavorable toxicology or other preclinical data, if we experience issues with the manufacture and supply of product candidates for our development programs, including issues with process development or manufacturing scale-up activities, whether such delays or disruptions are due to the COVID-19 pandemic or other reasons, we could incur additional and unexpected expenses as a result of such delays or disruptions and our business and financial results may be materially impacted. Furthermore, if we successfully develop and expect to obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, distribution and manufacturing. We are party to agreements with Archemix Corp., or Archemix, with respect to Zimura, the University of Florida Research Foundation, Incorporated, or UFRF, and Penn with respect to IC-100 and IC-200, UMass with respect to any potential product candidates from our miniCEP290 program, and the former equityholders of Inception 4 with respect to IC-500, in each case, that impose significant milestone payment obligations on us if we achieve specified clinical, regulatory and commercial milestones with respect to these product candidates, as well as certain royalties on net sales with respect to IC-100, IC-200 and any product candidates we choose to develop from our miniCEP290 program. It is likely that any future in-licensing or acquisition agreements that we enter into with respect to additional product candidates or technologies would include similar obligations.
We expect that we will continue to incur significant expenses as we:
•continue the development of Zimura in GA, STGD1 and potentially other indications;
63
•expand our outsourced manufacturing activities or establish commercial operations or sales, marketing and distribution capabilities, if we receive, or expect to receive, marketing approval for any of our product candidates;
•continue the development of IC-100, IC-200 and IC-500 and pursue our collaborative gene therapy sponsored research programs;
•in-license or acquire the rights to, and pursue the development of, other product candidates or technologies;
•seek marketing approval for any product candidates that successfully complete clinical trials;
•maintain, expand and protect our intellectual property portfolio;
•hire additional clinical, commercial, medical affairs, regulatory, manufacturing, quality control, quality assurance and scientific personnel; and
•expand our general and administrative functions to support our future growth.
Our ability to become and remain profitable depends on our ability to generate revenues in excess of our expenses. Our ability to generate revenues from product sales is dependent on our obtaining marketing approval for and commercializing our product candidates or any product candidates we may in-license or acquire. We may be unsuccessful in our efforts to develop and commercialize product candidates or in our efforts to in-license or acquire additional product candidates. Even if we succeed in developing and commercializing one or more of our product candidates, we may never achieve sufficient sales revenue to achieve or maintain profitability. See “—Risks Related to Product Development and Commercialization” for a further discussion of the risks we face in successfully developing and commercializing our product candidates and achieving profitability.
We expect we will require substantial, additional funding in order to complete the activities necessary to develop and commercialize one or more of our product candidates. If we are unable to raise capital when needed, we could be forced to delay, reduce or eliminate one or more of our product development programs or commercialization efforts. We may require additional funding beyond what we currently expect or sooner than we currently expect.
As of December 31, 2020, we had cash, cash equivalents and available for sale securities of $210.0 million. We estimate that our year-end 2021 cash, cash equivalents and available for sale securities will range between $130 million and $140 million. We also estimate that our cash, cash equivalents and available for sale securities will be sufficient to fund our planned capital expenditure requirements and operating expenses, excluding any potential approval or sales milestones payable to Archemix or any commercialization expenses for Zimura, into 2024. These estimates are based on our current business plan, which includes the continuation of our ongoing clinical development programs for Zimura, the progression of our IC-100 and IC-200 programs into the clinic, and the advancement of our IC-500 development program. These estimates also assume that we will enroll approximately 400 patients in the GATHER2 trial. These estimates do not reflect any additional expenditures related to potentially studying Zimura in other indications, or resulting from the potential in-licensing or acquisition of additional product candidates or technologies, commencement of any new sponsored research programs, or any associated development we may pursue. We have based these estimates on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect.
We expect we will require substantial, additional funding in order to complete the activities necessary to develop and commercialize one or more of our product candidates. Although the future development of our product candidates is highly uncertain, we expect the development of our product candidates will continue for at least the next several years. At this time, we cannot reasonably estimate the total remaining costs necessary to complete development, to complete process development and manufacturing scale-up and validation activities and to potentially seek marketing approval for any of our product candidates.
Our future capital requirements will depend on many factors, including:
•the scope, progress, costs and results of our current and any future Zimura clinical programs and any further development we may undertake to enable us to file a new drug application, or NDA, for Zimura in one or more indications;
•the scope, costs, progress, and results of process development, manufacturing scale-up and validation activities, analytical method development and qualification, and stability studies associated with Zimura and our other product candidates;
64
•the scope, progress, costs and results of our efforts to develop IC-100, IC-200 and IC-500, including activities to establish manufacturing capabilities and other preclinical development activities to enable us to file INDs for these product candidates;
•the scope, progress, costs and results from our collaborative gene therapy sponsored research programs, including costs related to the in-license and future development of any promising product candidates and technologies that emerge from these programs;
•our ability to establish collaborations on favorable terms, if at all, if we choose to do so, including any collaboration for the further development and potential commercialization of any of our product candidates;
•the timing and extent of delays or disruptions to our research and development programs as a result of the COVID-19 pandemic;
•the extent to which we in-license or acquire rights to, and undertake research or development of, additional product candidates or technologies;
•the costs, timing and outcome of regulatory filings and reviews of our product candidates;
•the costs of preparing, filing and prosecuting patent applications, maintaining and protecting our intellectual property rights and defending intellectual property-related claims;
•the timing, scope and cost of commercialization activities for any of our product candidates if we receive, or expect to receive, marketing approval for a product candidate; and
•subject to receipt of marketing approval, net revenue received from commercial sales of any of our product candidates, after milestone payments and royalty payments that we would be obligated to make.
We do not have any committed external source of funds. Our ability to raise adequate additional financing when needed, and on terms acceptable to us, will depend on many factors. These factors include investors' perceptions of the potential success of our ongoing business, including the development of our product candidates and other programs, and the potential future growth of our business. Additionally, these factors include general market conditions that also affect other companies. For example, the COVID-19 pandemic and governmental responses to the pandemic have caused volatility and uncertainty in the financial markets as well as additional volatility in the price of our stock, which may result in prospective investors being less likely to invest new capital. These factors may make raising capital difficult, and may result in us accepting terms that are unfavorable to us, especially if we are in need of financing at the particular time. Although we were able to raise approximately $150 million in net proceeds through our June 2020 public offering and concurrent private placement, we may not be able to successfully raise additional capital. The size of our company and our status as a company listed on The Nasdaq Global Select Market, or Nasdaq, may also limit our ability to raise financing. For example, our ability to raise adequate financing through a public offering may be limited by market conditions and SEC rules based on our current market capitalization. Nasdaq listing rules also generally limit the number of shares we may issue in a private placement to a number less than 20% of the number of shares of our common stock outstanding immediately prior to the transaction, unless we issue such shares at a premium, which investors may be unwilling to accept, or unless we obtain shareholder approval, which can be expensive and time-consuming and can add risk to our ability to complete the financing transaction. If we are unable to raise additional funds when needed, we may be required to delay, limit, reduce or terminate the development of one or more of our product candidates, our collaborative gene therapy sponsored research programs, or our future commercialization efforts.
We may require additional funding beyond what we currently expect due to unforeseen or other reasons. Our costs may exceed our expectations if we experience an issue in our clinical trials, such as issues with patient enrollment, the retention of enrolled patients, enrolled patients maintaining scheduled visits and receiving scheduled treatments, or the availability of drug supply, if we experience an issue in our preclinical development programs, such as unfavorable toxicology or other preclinical data, if we experience issues with manufacturing, or if we modify or further expand the scope of our clinical trials, preclinical development programs or collaborative gene therapy sponsored research programs. For example, we have decided to enroll approximately 25 additional patients in our ongoing STAR trial, with the goal of enrolling a total of approximately 120 patients, which will extend the duration of that trial and increase our costs of conducting that trial. Our costs may also exceed our expectations for other reasons, for example, if we are required by the FDA, the EMA, or regulatory authorities in other jurisdictions to perform clinical trials or nonclinical or other studies in addition to those we currently expect to conduct, if we experience issues with process development, establishing or scaling-up of manufacturing activities or activities to enable and
65
qualify second source suppliers, or if we decide to increase preclinical and clinical research and development activities, build internal research capabilities or pursue internal research efforts. For example, we are conducting the GATHER2 trial with the expectation that data collected from such trial, if it is positive, together with data from our GATHER1 trial, will be sufficient to support an application for marketing approval in the United States and the European Union and we may subsequently decide to, or be required by regulatory authorities to, enroll additional patients in the GATHER2 trial beyond our current expectations, conduct additional clinical trials for Zimura in GA or conduct additional non-clinical studies of Zimura in order to seek or maintain marketing approval or qualify for reimbursement approval. In addition, the COVID-19 pandemic may result in disruptions to the progress of the GATHER2 trial or the STAR trial, including slowing patient enrollment or causing enrolled patients to miss their scheduled visits or drop out in greater numbers than we expect, or disruptions to our other research and development programs, which could cause us to continue to expend our cash resources while not progressing our research and development programs as expeditiously as we would have had the pandemic not occurred or persisted. We may experience difficulty in enrolling or retaining patients or maintaining scheduled visits and treatments due to patients' fears of visiting clinical trial sites or ongoing restrictive measures requiring social distancing or limiting travel. For example, we are aware that, in the STAR trial, a number of patients initially enrolled in the trial missed consecutive visits during the early months of the COVID-19 pandemic. We do not know yet whether the number of missed visits will increase or decrease among the newly enrolled patients in the STAR trial or how many missed visits will occur in the GATHER2 trial, and whether and to what extent missed visits may impact the results of any of the trials. As a result of any of the above, we may need or may seek to obtain additional funding for our continuing operations sooner or in greater amounts than expected.
Our need for additional financing may continue even if we are able to successfully develop one or more of our product candidates. Our future commercial revenues, if any, will be derived from sales of such product candidates, which may not be available for at least several years following completion of successful product development, if at all. In addition, if approved, our product candidates may not achieve commercial success. Even if those products are successful and we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Under most, if not all, of the foregoing circumstances, we may need to obtain substantial additional financing to achieve our business objectives.
Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.
Until such time, if ever, when we can generate substantial product revenues, we may need or may seek to finance our operations through a combination of equity offerings, debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans. To the extent that we raise additional capital through the sale of equity or convertible debt securities, our existing stockholders' ownership interests would be diluted, and the terms of these new securities may include liquidation or other preferences that adversely affect our existing stockholders' rights as common stockholders. The dilutive effect of future equity issuances may be substantial, depending on the price of our common stock at the time of such capital raise, with a lower stock price translating to greater dilution for existing stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, declaring dividends or entering into certain investments or transactions.
In addition, we have issued, and may in the future issue additional, equity securities as consideration for business development transactions, which may also dilute our existing stockholders' ownership interests. For example, under the agreement and plan of merger pursuant to which we acquired Inception 4, or the Inception 4 Merger Agreement, we issued an aggregate of 5,174,727 shares of our common stock as up-front consideration to the former equityholders of Inception 4. The Inception 4 Merger Agreement also requires us to make payments to the former equityholders of Inception 4 upon the achievement of certain clinical and regulatory milestones, subject to the terms and conditions set forth in the Inception 4 Merger Agreement. Those milestone payments will be in the form of shares of our common stock, calculated based on the price of our common stock over a five-trading day period preceding the achievement of the relevant milestone, unless and until the issuance of such shares would, together with all other shares issued under the Inception 4 Merger Agreement, exceed an overall maximum limit of approximately 7.2 million shares, which is equal to 19.9% of the number of issued and outstanding shares of our common stock as of the close of business on the business day prior to the closing date of our acquisition of Inception 4, and will be payable in cash thereafter. In July 2019, we also issued 75,000 shares of our common stock to UMass as partial upfront consideration for the in-license of our miniCEP290 program, and are obligated to issue up to 75,000 additional shares to UMass upon the achievement of a development milestone.
If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, products or product candidates or grant licenses on terms that may not be favorable to us. If we choose to pursue a collaboration for any
66
of our product candidates, we may be required to relinquish certain valuable rights depending on the terms of such a transaction. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to grant rights to develop and market products or product candidates that we would otherwise prefer to develop and market ourselves.
The COVID-19 pandemic, which is a fluid and evolving situation, has adversely affected and may continue to negatively affect our business and operations in a number of ways, and its long-term effects are uncertain. In addition, the pandemic has caused substantial disruption in the financial markets and economies, which could adversely affect our business and operations.
The COVID-19 pandemic, which began in December 2019, has spread worldwide. A majority of the world's population has been affected by government efforts to slow the spread of the outbreak through stay-at-home and social distancing orders, shutdowns of businesses and public places, heightened border security, travel restrictions, quarantines and other measures. The COVID-19 pandemic and government measures taken in response have had a significant impact, both direct and indirect, on businesses and commerce, as a substantial number of people have been required to stay and work from home; worker shortages have occurred; supply chains have been disrupted; facilities and production have been suspended; and demand for certain goods and services, such as medical services and supplies, has spiked, while demand for other goods and services, such as travel and conferences, has fallen.
Beginning in March 2020, the COVID-19 pandemic and measures taken to contain it have affected our business and operations in a number of ways. These include, but are not limited to, the following:
•In March 2020, we decided to delay the initiation of patient enrollment in our GATHER2 trial. Although we initiated patient enrollment in June 2020 and our clinical trial sites are continuing to enroll patients, we and our clinical trial sites are doing so cautiously in light of new health and safety practices put into place as a result of the COVID-19 pandemic. We are continuing to monitor the situation closely and may need to slow down or stop patient enrollment in certain geographies depending on the local situation. In addition, we have added sites to this trial because of the ongoing and variable nature of the pandemic and its potential impact on patient recruitment and retention. Health authorities and ethics committees in certain countries have reduced their staff and operations due to the COVID-19 pandemic. This reduction in operations has resulted in delays to the approval of our trial in certain countries outside the United States and delays in the activation process for a number of our planned clinical trial sites. We may face difficulties in recruiting or retaining patients or maintaining scheduled visits to the extent patients are affected by the virus or are fearful of visiting or traveling to our clinical trial sites because of the pandemic. We are aware that a number of patients initially enrolled in the STAR trial missed consecutive visits during the early months of the pandemic. We do not yet know whether the number of missed visits will increase or decrease among the newly enrolled patients in the STAR trial or how many missed visits will occur in the GATHER2 trial, or what the impact of missed visits may be on trial results, especially because we are masked to the treatment of patients during the conduct of the trials. At this time, we do not know whether there will be further impacts on the timing and progress of patient enrollment or on patient retention or maintenance of scheduled visits in any of our ongoing or planned clinical trials as a result of the COVID-19 pandemic.
•Although most of our clinical trial sites have reopened and are continuing to conduct patient visits for our clinical trials, they are doing so with fewer staff and other restrictions and many of them are focusing on more urgent matters rather than clinical trials. We are engaging with our clinical trial sites, with the goal of monitoring the health and well-being of our patients who remain in our trials and maintaining their scheduled visits and treatments. Where possible, we and our clinical investigators have instituted practices such as flexible scheduling of visits for patients and remote monitoring, and we have also provided patient travel services and personal protective equipment to support our sites and patients. Recently, a number of our clinical trial sites have been scaling back their operations because of recent surges in COVID-19 cases or new lockdown measures being imposed. We have been and will continue to monitor the situation closely.
•In some instances, our third-party contract manufacturers, academic research collaborators and contract research organizations have limited their operations and staff, which has resulted in delays to some of our manufacturing and research and development activities and limited our ability to be on site to oversee these activities. For example, the closure of animal research laboratories at the UMMS for several months during 2020 caused delays to the progress of, and to our timelines for receipt of data from, our collaborative gene therapy sponsored research programs. Additionally, we were unable to perform person-in-plant (PIP) observations on a number of critical manufacturing activities at our CDMO for IC-100 and IC-200, which caused minor delays to our manufacturing timelines for both
67
product candidates. Furthermore, because of the COVID-19 pandemic and restrictions on remote auditing due to privacy and other concerns, we have experienced difficulties and delays in performing audits on most of our clinical trial sites.
•Shortages, delays and governmental restrictions arising from the COVID-19 pandemic have disrupted and may continue to disrupt the ability of our contract manufacturers to procure items, such as raw materials, that are essential for the manufacture of our product candidates. For example, during 2020, our contract manufacturer for IC-500 experienced a shortage in obtaining one of the critical raw materials that was sourced from China, which was caused by the shutdown of local suppliers and the slowdown in trade due to the COVID-19 pandemic. This shortage delayed our process development activities for the drug substance for IC-500 by a number of months. Additionally, there is increased demand for the vials we are planning to use for the fill/finish of Zimura drug product, which governments and other companies intend to use for COVID-19 vaccines and medicines. This increased demand may limit our ability to obtain these vials for our own needs.
•We instituted company-wide remote working starting in March 2020 and expect to continue working remotely for the foreseeable future. We have been relying on remote means of working and communication both internally and externally. We are continuing to monitor and support the health and well-being of our employees and their productivity as remote working continues.
The progression of the COVID-19 pandemic remains fluid and its impact on our business and operations remains uncertain. From late 2020 to January 2021, many countries and regions, including most states in the United States, experienced a surge in the number of new cases, including as a result of several new mutations to the SARS-COV-2 virus, which caused public health authorities to reimpose restrictive measures. Although the number of new cases in the United States in February 2021 appears to have receded from the January highs, this trend may not continue or may reverse. In addition, although the FDA has granted emergency use authorization to three vaccines for this disease, there continue to be challenges with distributing vaccines and administering them to the general population, and the long-term safety and efficacy and ability of these vaccines to slow transmission are largely unknown. As a result, governments may continue to deploy measures to contain the pandemic for a prolonged period of time. The full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition will depend on developments that are highly uncertain and cannot be accurately predicted, including new information that may emerge concerning COVID-19, the actions taken to contain it or lessen its impact and the economic impact on local, regional, national and international markets. If the delays and other disruptions due to the pandemic become prolonged or more extensive, then we may experience further delays or disruptions to our research and development programs and our financial position, results of operations or cash flows for future periods may be materially affected.
In addition, many companies have been using force majeure clauses in their contracts to excuse or delay performing under their contracts. Our contract manufacturers, academic research collaborators, contract research organizations and other third parties on whom we rely for goods or services may make similar claims. If any such force majeure claims were successful, then not only would our timelines be delayed but also our right to recover for any economic damages due to the delay would be limited. Because we rely on many single-source suppliers, any such claims from them are likely to result in a delay to our timelines or otherwise adversely affect our operations or financial position.
We cannot foresee if and when the COVID-19 pandemic will be effectively contained, nor can we predict the severity and duration of the impact of the pandemic on our financial condition or operations. Even if the pandemic is contained and the economy is largely reopened, the pandemic may recur and the existing measures may be re-imposed. If the COVID-19 pandemic is not effectively and timely controlled, we may experience prolonged disruptions to our clinical trials or supply chains, extended closures of facilities, such as clinical trial sites, academic research centers and suppliers, including single source suppliers, and delays in interactions with regulatory agencies or obtaining approvals for our product candidates. Many economists are predicting that the pandemic may have significant or long-lasting effects on economies worldwide. If the effects of COVID-19 on the financial markets and the global economy persist, they could hamper our ability to raise additional finances. Additional public health crises and natural disasters, such as future epidemics or pandemics or those resulting from the effects of climate change, may arise in the future. Any of these events may materially and adversely affect our business operations and financial condition.
Our strategy of obtaining additional rights to products, product candidates or technologies for the treatment of retinal diseases may not be successful.
An element of our strategy has been to expand our pipeline through in-licensing or acquiring the rights to products, product candidates or technologies that would complement our strategic goals as well as other compelling ophthalmology
68
opportunities. Since early 2018, we have completed multiple acquisition, in-license, exclusive option and sponsored research arrangements for product candidates and other technologies intended to treat retinal diseases. We plan to continue to evaluate additional opportunities to in-license or acquire products, product candidates and technologies on a selective and targeted basis, including technologies that may complement our existing product candidates and other strategic lifecycle initiatives. We may also continue to consider other alternatives, including mergers or other transactions involving our company as a whole or other collaboration transactions, including collaboration or out-license opportunities for further development and potential commercialization of our product candidates. Our business development efforts may fail to result in our acquiring rights to additional products, product candidates or technologies, or may result in our consummating transactions with which you do not agree.
We may be unable to in-license or acquire the rights to any such products, product candidates or technologies from third parties for several reasons. The success of this strategy depends partly upon our ability to identify, select and acquire or in-license promising product candidates and technologies. There are currently a limited number of available product candidates or technologies for the treatment of diseases affecting the retina and the competition for those assets is intense. The process of proposing, negotiating and implementing a license or acquisition of a product candidate or technology is lengthy and complex. With respect to potential product candidates or technologies for which we have entered into option agreements or sponsored research agreements for which we have option rights, our agreements generally do not have fixed economic or other key terms for definitive agreements, and we may not obtain favorable terms if and when we choose to exercise our option to acquire or in-license any product candidates or technologies.
The in-licensing and acquisition of pharmaceutical products is an area characterized by intense competition, and a number of companies (both more established and early stage biotechnology companies) are also pursuing strategies to in-license or acquire product candidates or technologies that we may consider attractive. We believe that other companies may be
particularly active in pursuing opportunities to in-license or acquire gene therapy opportunities. More established companies may have a competitive advantage over us due to their size, cash resources and greater research, preclinical or clinical development, manufacturing or commercialization capabilities, while earlier stage companies may be more aggressive or have a higher risk tolerance. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to in-license or acquire the rights to the relevant product candidate or technology on terms that would allow us to make an appropriate return on our investment. Moreover, we may devote resources to potential acquisitions or in-licensing opportunities that are never completed, or we may fail to realize the anticipated benefits of such efforts or we may incorrectly judge the value of an acquired or in-licensed product candidate or technology.
Further, any product candidate that we acquire or in-license would most likely require additional development efforts prior to commercial sale, including extensive clinical testing and approval by the FDA and applicable foreign regulatory authorities. All product candidates are prone to risks of failure typical of pharmaceutical product development, including the possibility that a product candidate would not be shown to be sufficiently safe and effective for approval by regulatory authorities.
If we are unable to successfully obtain rights to suitable product candidates or technologies, our business, financial condition and prospects for growth could suffer. In addition, acquisitions and in-licensing arrangements for product candidates and technologies are inherently risky, and ultimately, if we do not complete an announced acquisition or license transaction or integrate an acquired or licensed product candidate or technology successfully and in a timely manner, we may not realize the benefits of the acquisition or license to the extent anticipated and the perception of the effectiveness of our management team and our company may suffer in the marketplace. In addition, even if we are able to successfully identify, negotiate and execute one or more transactions to acquire or in-license new product candidates or technologies, our expenses and short-term costs may increase materially and adversely affect our liquidity.
In addition, acquisitions and in-licenses may entail numerous operational, financial and legal risks, including:
•exposure to known and unknown liabilities, including possible intellectual property infringement claims, violations of laws, tax liabilities and commercial disputes;
•incurrence of substantial debt, dilutive issuances of securities or depletion of cash to pay for acquisitions or in-licensing transactions;
•higher than expected acquisition and integration costs;
•difficulty in combining the operations and personnel of any acquired businesses with our operations and personnel;
•inability to maintain uniform standards, controls, procedures and policies;
69
•restructuring charges related to eliminating redundancies or disposing of assets as part of any such combination;
•large write-offs and difficulties in assessing the relative percentages of in-process research and development expense that can be immediately written off as compared to the amount that must be amortized over the appropriate life of the asset;
•increased amortization expenses or, in the event that we write-down the value of acquired assets, impairment losses;
•impairment of relationships with key suppliers or customers of any acquired businesses due to changes in management and ownership;
•inability to retain personnel, key customers, distributors, vendors and other business collaborators integral to an in-licensed or acquired product candidate or technology;
•potential failure of the due diligence process to identify significant problems, liabilities or other shortcomings or challenges of an acquired or licensed product candidate or technology, including problems, liabilities or other shortcomings or challenges with respect to intellectual property, data or product quality, revenue recognition or other accounting practices, partner disputes or issues and other legal and financial contingencies and known and unknown liabilities; and
•entry into therapeutic approaches, indications or markets in which we have no or limited direct prior development or commercial experience and where competitors in such markets have stronger market positions.
We and certain of our current and former board members and executive officers have been named as defendants in lawsuits that could result in substantial costs and divert management’s attention.
We and certain of our current and former executive officers have been named as defendants in a purported consolidated putative class action lawsuit initiated in 2017 that generally alleges that we and certain of our officers violated Sections 10(b) and/or 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder by making allegedly false and/or misleading statements concerning the results of our Phase 2b trial and the prospects of our Phase 3 trials for Fovista in combination with anti-VEGF agents for the treatment of wet AMD. Certain current and former members of our board of directors and current and former officers have also been named as defendants in a shareholder derivative action initiated in August 2018, which generally alleges that the defendants breached their fiduciary duties to our company by failing to oversee our business during the period of the Phase 2b and Phase 3 clinical trials of Fovista. These complaints seek equitable and/or injunctive relief, unspecified damages, attorneys’ fees, and other costs. In September 2019, the court issued an order dismissing some, but not all, of the allegations in the class action lawsuit and denied our motion to dismiss the shareholder derivative action. The class action lawsuit is currently in the discovery phase. The shareholder derivative action has been stayed while a special litigation committee of our board of directors investigates the allegations contained in the complaint. We and the defendants continue to deny any and all allegations of wrongdoing and intend to vigorously defend against these lawsuits. We are unable, however, to predict the outcome of these matters at this time. Moreover, any conclusion of these matters in a manner adverse to us and for which we incur substantial costs or damages not covered by our directors’ and officers’ liability insurance would have a material adverse effect on our financial condition and business. In addition, the litigation, including in responding to discovery requests, has caused our management and board of directors to divert time and attention to the litigation and could adversely impact our reputation and further divert management and our board of directors’ attention and resources from other priorities, including the execution of our business plan and strategies that are important to our ability to grow our business, any of which could have a material adverse effect on our business. Additional lawsuits may be filed.
Risks Related to Product Development and Commercialization
Companies in our industry face a wide range of challenging activities, each of which entails separate, and in many cases substantial, risk.
The long-term success of our company, and our ability to become profitable as a biopharmaceutical company, will require us to be successful in a range of challenging activities, including:
•designing, conducting and successfully completing preclinical research and development activities, including preclinical efficacy and IND-enabling studies, for our product candidates or product candidates we are interested
70
in in-licensing or acquiring, including those we may evaluate as part of our collaborative gene therapy sponsored research programs;
•making arrangements with third-party manufacturers and providers of starting materials for our product candidates, and having those manufacturers successfully develop manufacturing processes for drug substance and drug product and provide adequate amounts of drug product for preclinical and clinical activities in accordance with our expectations and regulatory requirements;
•designing, conducting and completing clinical trials for our product candidates;

Each of these activities has associated risks, many of which are detailed below and throughout this “Risk Factors” section. We may never succeed in these activities and, even if we do, may never generate revenues from product sales that are significant enough to achieve commercial success and profitability. Our failure to be commercially successful and profitable would decrease the value of our company and could impair our ability to raise capital, expand our business, maintain our research and development efforts, diversify our product offerings or continue our operations. A decrease in the value of our company would also cause our stockholders to lose all or part of their investment.

Drug development is a highly uncertain undertaking. Our research and development efforts may not be successful or may be delayed for any number of reasons, in which case potential clinical development, marketing approval or commercialization of our product candidates could be prevented or delayed.
Before obtaining approval from regulatory authorities for the sale of any product candidate, we must conduct extensive clinical trials to demonstrate the safety and efficacy of our product candidate in humans. Prior to initiating clinical trials, we must complete extensive preclinical testing of a product candidate, including, in most cases, preclinical efficacy experiments as well as IND-enabling toxicology studies. Drug research, including the gene therapy research we are sponsoring with UMMS, may never yield a product candidate for preclinical or clinical development. Early stage and later stage research experiments and preclinical studies, including the IND-enabling toxicology study we are conducting for IC-200 and similar studies we are planning to conduct for IC-500, may fail at any point or produce unacceptable results for any number of reasons, and even if completed, may be time-consuming and expensive. As a result of these risks, a potentially promising product candidate may never be tested in humans.
Once it commences, clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to outcome. A failure of one or more clinical trials can occur at any stage of testing. The outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. For example, our pivotal Phase 3 Fovista program for the treatment of wet AMD failed to produce positive safety and efficacy data that support the use of Fovista in wet AMD, despite the results from preclinical testing and earlier clinical trials of Fovista, including a large Phase 2b trial with a statistically significant efficacy signal. Additionally, although the 18-month results from our GATHER1 trial supported the 12-month results in this trial, at which time Zimura met the prespecified primary endpoint in reducing the mean rate of GA growth in patients with GA with statistical significance across both the Zimura 2 mg and Zimura 4 mg treatment groups when compared to the corresponding sham control groups while maintaining a favorable safety profile, these results may not be replicated in the GATHER2 trial or any future trials we may conduct for Zimura in GA. Preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their products.
We may experience numerous unforeseen events during drug development that could delay or prevent our ability to receive marketing approval or commercialize our product candidates. These risks include, but are not limited to, the following:
•we may not be able to generate sufficient preclinical, toxicology, or other in vivo or in vitro data to support the initiation of clinical trials for any preclinical product candidates that we are developing;
•we or our contract manufacturers may be unable to develop a viable manufacturing process for any product candidates that we are developing;
•the supply or quality of our product candidates or other materials necessary to conduct preclinical development and clinical trials of our product candidates may be insufficient or we may face delays in the manufacture and supply of our product candidates for any number of reasons, including as a result of interruptions in our supply chain, including in relation to the procurement or quality of starting materials, such as plasmids used for the manufacture of our gene therapy product candidates and the polyethylene glycol, or PEG, used for the manufacture of Zimura, and issues with the packaging, distribution, storage and import/export of materials and products;
•we or our contract research organizations may be unable to complete necessary analytical development for and testing of our product candidates, including assays for assessing the potency of our gene therapy product candidates;
•we may not be able to successfully scale up or validate a manufacturing process for one or more of our product candidates, and may need to rely on second source suppliers for adequate supply of drug substance and/or drug product in line with our needs and expectations;
•regulators or institutional review boards may not agree with our clinical trial designs, including our selection of endpoints, or may not authorize us or our investigators to commence a clinical trial or conduct a clinical trial at a prospective trial site;
72
•we may experience delays in reaching, or fail to reach, agreement on acceptable clinical trial contracts or clinical trial protocols with prospective contract research organizations or clinical trial sites, especially in cases where we are working with contract research organizations or clinical trial sites we have not worked with previously;
•our contract research organizations, clinical trial sites, contract manufacturers, providers of starting materials and packagers and analytical testing service providers may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all;
•we, through our clinical trial sites, may not be able to locate and enroll a sufficient number of eligible patients to participate in our clinical trials as required by the FDA or similar regulatory authorities outside the United States, especially in our clinical trials for orphan or other rare diseases;
•we, through our clinical trial sites, may not be able to maintain enrolled patients for scheduled visits and treatments, or to retain patients altogether, especially in light of the COVID-19 pandemic, which could result in missing data from our clinical trials, potentially leading to uninterpretable results or a clinical trial not being sufficiently powered to demonstrate an efficacy benefit;
•we may decide, or regulators or institutional review boards may require us, to suspend or terminate clinical trials for various reasons, including noncompliance with regulatory requirements, including GCPs, or a finding that the participants are being exposed to unacceptable health risks;
•as there are no therapies approved for GA, Stargardt disease, RHO-adRP or any BEST1-related IRDs, in either the United States or the European Union, the regulatory pathway for product candidates in those indications, including the selection of efficacy endpoints, is highly uncertain;
•there may be changes in regulatory requirements and guidance or we may have changes in trial design that require amending or submitting new clinical trial protocols;
•there may be changes in the standard of care on which a clinical development plan was based, which may require new or additional trials;
•we may decide, or regulators may require us, to conduct additional clinical trials or non-clinical studies beyond those we currently contemplate or to abandon product development programs;
•the number of patients required for clinical trials of our product candidates to demonstrate statistically significant results may be larger than we anticipate. This risk may be heightened for clinical trials in orphan diseases, for which the natural history of the disease is less understood, making it more difficult to predict the drug effect required to adequately demonstrate efficacy, and because there are fewer affected individuals available to participate in clinical trials; and
•the cost of clinical trials of our product candidates, including the costs of manufacturing activities to support those clinical trials, may be greater than we anticipate.
If we are required to conduct additional clinical trials or other testing of our product candidates beyond those that we contemplate, if we otherwise change our clinical development plans, if we are unable to successfully complete clinical trials of our product candidates or other testing, if the results of these trials or tests are not positive or are only modestly positive or if there are safety concerns, we may:
•be delayed in obtaining marketing approval for our product candidates;
•not obtain marketing approval at all;
•obtain approval for indications or patient populations that are not as broad as intended or desired;
•obtain approval with labeling that includes significant use limitations, distribution restrictions or safety warnings, including boxed warnings;
•be subject to additional post-marketing testing requirements; or
73
•have the product removed from the market after obtaining marketing approval.
Despite our ongoing efforts, we may not complete any of our ongoing or planned development activities for our product candidates. The timing of the completion of, and the availability of results from, development activities, especially clinical trials, is difficult to predict. For clinical trials in particular, we do not know whether they will begin as planned, will need to be restructured or will be completed on schedule, or at all. The progress of our clinical trials may be dependent on macro-economic events beyond our control, such as the COVID-19 pandemic. For example, although we are continuing to enroll patients in the GATHER2 trial, we may later decide to or be required to slow down or pause patient recruitment due to the continued persistence of the pandemic or as a result of governmental measures instituted in response to the pandemic. Furthermore, our development plans may change based on feedback we may receive from regulatory authorities throughout the development process or for other reasons. For example, our expectations regarding the remaining clinical requirements to demonstrate the safety and efficacy of Zimura for the treatment of GA secondary to AMD in a manner sufficient to support an application for marketing approval to the FDA and EMA are based on our review of the 12-month and 18-month data from the GATHER1 trial as well as informal discussions with the FDA. Our expectations regarding the minimum clinical requirements to demonstrate the safety and efficacy of Zimura for GA could be incorrect or may change as we continue to have interactions with the FDA, as we continue to review and analyze data from our GATHER1 trial, as we conduct our GATHER2 trial, and as new regulatory or third party information, including third-party clinical data or information from prospective collaborators or licensees, becomes available. Additionally, we recently revised our development plans and timelines for IC-500 after completing a review of this product candidate and the potential market for such candidate. If we experience delays in manufacturing, testing or marketing approvals, our product development costs would increase. Significant product development delays also could allow our competitors to bring products to market before we do, could impair our ability to successfully commercialize our product candidates, including by shortening any periods during which we may have the exclusive right to commercialize our product candidates, and may otherwise harm our business and results of operations.
Our development of Zimura is based on a novel mechanism of action that is unproven in GA and STGD1 and poses a number of scientific and other risks, and we may not be successful in developing Zimura in the indications we are pursuing or in any other indication we may choose to pursue.
We are currently targeting GA, an advanced form of AMD, and STGD1 with Zimura. The causes of AMD are not completely understood. In addition to advanced age, there are environmental and genetic risk factors that contribute to the development of AMD including ocular pigmentation, dietary factors, a positive family history for AMD, high blood pressure and smoking. Although we believe there is a scientific rationale for pursuing the development of inhibitors of selective molecular targets, including complement C5, as potential pharmaceutical treatments for GA secondary to AMD, and that the results from our GATHER1 trial of Zimura in GA support our view, this approach may not prove successful for treating GA secondary to AMD in a clinically meaningful way. Similarly, although there is non-clinical scientific literature supporting the potential use of complement system inhibitors for the treatment of STGD1, we have not yet completed a clinical trial assessing Zimura for the treatment of STGD1 and do not have any unmasked data regarding the efficacy of Zimura in this indication. As a result, this approach may not prove clinically successful.
Zimura is designed to inhibit complement C5. There are no FDA or EMA approved products that utilize C5 inhibition as a mechanism of action to treat GA or STGD1. There have been other investigational products using complement inhibition as a mechanism of action for the treatment of GA, including inhibition of C5, that proved to be unsuccessful, even in later stage clinical trials. Even though our GATHER1 trial of Zimura in GA met its prespecified primary endpoint at month 12 and continued to show positive treatment effect at month 18, this mechanism of action may not prove safe and effective for the treatment of GA, STGD1 or any other indication for which we may develop Zimura.
We may decide to pursue clinical development of Zimura for other indications, including those we previously studied such as wet AMD and IPCV and other indications such as earlier stages of AMD. Similar to GA and STGD1, Zimura, and the use of C5 inhibition, are unproven in those indications and we may not be successful in our efforts to develop Zimura for those indications.
We are continuing to review and analyze the results and individual patient level data from the GATHER1 trial. Further analysis may lead to the discovery of information that is inconsistent with our initial conclusions regarding the GATHER1 data. The GATHER2 trial may yield results that are different from the results observed in the GATHER1 trial. An unfavorable result from the GATHER2 trial likely would materially adversely affect our ability to obtain approval for Zimura in GA.
Although the 18-month data from the GATHER1 trial supported the results we observed at 12 months, these data are subject to several limitations. In accordance with the prespecified statistical analysis plan for the trial, we only performed
74
descriptive analysis of the 18-month efficacy data. Although the favorable safety profile for Zimura was maintained at month 18, individual, unmasked patient data may indicate that our conclusions were not well founded due to inconsistencies, data entry errors or because of unknown variables or patient sub-groups that could potentially be driving the results in one or more treatment groups. Although not reported as related to Zimura by investigators, we observed an increase in the number of investigator-reported cases of CNV in the Zimura treatment groups in the GATHER1 trial as compared to the sham control groups. Additionally, we learned from our independent masked reading center that the retinal images of one of the patients in the Zimura 4 mg group showed evidence of CNV in the study eye that was not reported by the investigator. As we continue to evaluate the individual, unmasked patient data from the GATHER1 trial, we may learn of additional cases of non-investigator reported safety issues, which may affect the safety profile of Zimura.
Unlike the GATHER1 trial, the GATHER2 trial includes only one treatment arm, Zimura 2 mg, in addition to a control arm. Several Phase 3 clinical trials for ophthalmic product candidates that have been, or are currently being, conducted by other sponsors include multiple treatment arms, either different doses or treatment regimens, in addition to a control arm. The FDA has expressed that including multiple study doses or treatment regimens within a single trial helps mitigate the risk of bias in the trial and is therefore recommended, although not required. We believe that the anatomical measure used as the primary efficacy endpoint in both our GATHER1 trial and our GATHER2 trial, the mean rate of change in GA growth, as evaluated by an independent, masked reading center, is not subject to bias. We have decided to proceed with only one treatment arm in the GATHER2 trial consisting of a single monthly administration of Zimura 2 mg, because the 12-month data from the GATHER1 trial suggested that monthly administration of Zimura 2 mg provides a similar benefit (approximately 27%) in reducing the mean rate of GA growth over 12 months as compared to the corresponding sham control group, as measured by our primary endpoint, as Zimura 4 mg, and these results are supported by the results of the 18-month data, and because we want to avoid the treatment burden associated with the Zimura 4 mg dose evaluated in our GATHER1 trial. Additionally, for our GATHER2 trial, because we want to begin to evaluate the efficacy of a less frequent dosing regimen, we plan to re-randomize the patients in the monthly Zimura 2 mg treatment arm at 12 months and evaluate dosing Zimura 2 mg every other month, a dosing regimen which we have not previously studied, in half of those patients during the second 12 months of the trial. The GATHER2 trial, however, is not designed to reliably assess any differences we observe between these treatment groups at 24 months with statistical significance and the label we would seek for Zimura in GA, if the results from the GATHER2 trial are positive, would in all likelihood provide for monthly administration of Zimura.
We are conducting the GATHER2 trial at many clinical trial sites and in many countries that were not included in the GATHER1 trial. The introduction of new sites, and the resulting involvement of new treating physicians, as well as potentially different patient demographics, can introduce additional variability into the conduct of the trial and may result in greater variability of patient outcomes, which could adversely affect our ability to detect statistically significant differences between patients treated with Zimura 2 mg and patients receiving sham control.
In addition, the 12-month and 18-month data from the GATHER1 trial suggested there is an overall dose response relationship in which higher doses of Zimura (for example, the 4 mg and the 2 mg doses) corresponded to a greater reduction in the mean rate of GA growth as compared to the corresponding sham group as compared to lower doses of Zimura (for example, the 1 mg dose). For our GATHER2 trial, for the reasons stated above, we have decided to proceed with only a 2 mg dose treatment arm and not include a 4 mg dose treatment arm. The 2 mg dose may prove not to be efficacious in treating GA. Additionally, unlike the protocol for the GATHER1 trial, the protocol of the GATHER2 trial provides that patients who develop CNV in the study eye in the trial may remain in the trial and receive either Lucentis or Eylea in accordance with the label for that anti-VEGF agent, and that measurements of these patients' GA will be included in the primary efficacy analysis if their fundus autofluorescence, or FAF, images can be reliably assessed by the masked reading center. The retention of these patients in the GATHER2 trial may introduce additional variability not present in the GATHER1 trial, as we do not have any data regarding the progression of GA in patients with CNV who receive treatment with an anti-VEGF agent. Moreover, if a significant number of patients develop CNV in the study eye and these patients' FAF images are not reliably assessable, or if more patients than we anticipate drop out or their data is otherwise missing, any such occurrence would reduce the number of patients from whom data is available for analyzing the primary endpoint for this trial and the GATHER2 trial could be underpowered to demonstrate a potential clinical benefit for Zimura in GA with statistical significance.
75
Our intended regulatory pathway for generating sufficient safety and efficacy data to submit an NDA and potentially obtain marketing approval for Zimura for GA is subject to a number of assumptions, including that we may be able to rely on the results from our GATHER1 and GATHER2 trials as two well-controlled, Phase 3 trials typically required by the FDA. The FDA, EMA and other regulatory authorities may not accept the results of the GATHER1 trial as a Phase 3 clinical trial, or may not agree with our selection of the primary endpoint for the GATHER1 and GATHER2 trials or the statistical analysis we performed. We may decide to or may be required to enroll additional patients, collect additional safety data or conduct additional clinical trials or non-clinical studies to seek or obtain approval for Zimura in GA.
Based on the results of our GATHER1 trial, additional statistical analysis we have performed and informal discussions we have had with the FDA, we believe that the efficacy results from this trial could potentially satisfy the FDA’s requirements as one of the two pivotal clinical trials typically required for marketing approval. This belief is based on many assumptions, including that a reduction in mean rate of GA growth over 12 months, measured by FAF based on readings at three time points: baseline, month 6 and month 12, calculated using the square root transformation of the GA area, is a primary endpoint of clinical relevance, in the absence of a demonstrated reduction in the loss of vision, and that data from the GATHER1 trial is robust. The FDA, the EMA or other regulatory authorities may not agree with our view that the observed reduction in the rate of GA growth, calculated using the square root transformation, is clinically relevant or meaningful, or may require us to correlate this reduction in rate of GA growth with another outcome more directly associated with visual function. We are not currently planning to include visual function measures as primary or secondary efficacy endpoints in the GATHER2 trial and vision will be assessed as a safety endpoint. The FDA, the EMA or other regulatory authorities may disagree with our conclusion regarding the robustness of the data from the GATHER1 trial based on our sensitivity analyses or may conduct their own sensitivity analyses yielding different results. Even if we meet with the FDA, EMA or other regulatory authorities, we likely will not have an opportunity to obtain definitive confirmation from the FDA, EMA or other regulatory authorities regarding the sufficiency or robustness of the data from our clinical trials, including the GATHER1 trial, until such time as we submit an application for marketing approval and receive a response from the applicable authority. If the GATHER1 trial results are not considered robust, or if regulatory authorities do not accept our primary endpoint as clinically relevant without correlation to an outcome more directly associated with visual function, in order to seek marketing approval we may need to conduct, in addition to the GATHER2 trial, one or more additional, well-controlled clinical trials that meets the applicable regulatory requirements in order to obtain sufficiently robust data for an acceptable endpoint to support marketing approval.
The FDA, EMA or other regulatory authorities may not agree with the methodologies we used to perform the statistical analysis of the GATHER1 trial results. In particular, they may not agree with how we performed the comparisons of patients receiving Zimura 2 mg with patients in the sham groups, as the comparisons draw upon patients who were enrolled into two different parts of the trial, using different randomization ratios and different vision criteria. In addition, they may not agree with the validity of our MRM analysis, which imputes the values of missing data based on observed data. We plan to use the same MRM analysis in the GATHER2 trial. Moreover, the FDA, EMA or other regulatory authorities may disagree with our inclusion in our efficacy analysis of patients who do not strictly meet all eligibility criteria, or whose treatment or assessments in the clinical trial deviated from the clinical trial protocol on one or more occasions. The FDA, EMA or other regulatory authorities may take issue with the degree of data that are missing from the clinical data set from our GATHER1 trial, or with the rate at which patients withdrew from the trial. To the extent patients miss critical visits or drop out of the GATHER2 trial, we face a similar risk with GATHER2.
Although we believe that our GATHER1 trial was well-controlled, with appropriate eligibility criteria and appropriate stratification for baseline characteristics, the FDA, EMA or other regulatory authorities may not agree with the methodologies we used to determine patient eligibility and to randomize patients to the various treatment groups and therefore may not agree that the comparisons we have made for mean rate of GA growth are statistically valid. The FDA, EMA or other regulatory authorities may take issue with the number of modifications we introduced to the GATHER1 trial following its commencement, which they may view as introducing additional uncontrolled variables, invalidating the comparisons across groups. In particular, the FDA, EMA or other regulatory authorities may view the change in enrollment criteria applied in the various modifications as changing the nature of the patients enrolled, thus rendering the results of the trial as uninterpretable, or may disagree with our decision to remove patients who develop CNV in their study eye from future treatments and assessments as inappropriate, concluding that it may have resulted in unmitigated or uncontrolled bias in the safety or efficacy results from the trial.
Based on informal discussions with the FDA, following the GATHER1 trial, we believe we need to conduct one additional clinical trial with enough patients such that we will have safety data for a minimum of 300 patients having received the dose of Zimura for which we are seeking approval, or a higher Zimura dose, independent of indication, for a minimum of 12 months, with 24-month safety data available for some portion, but not all, of these 300 patients. This additional clinical trial would need to be well-controlled, with a primary efficacy analysis at the 12 month time point or later. We believe that if we were to file an application for marketing approval for Zimura for GA, we would be able to rely on safety data from our GATHER1 and GATHER2 trials in GA, as well as our STAR trial evaluating Zimura for STGD1. We also believe that, if the
76
data from the GATHER2 trial are positive, we would be able to submit our application following the primary efficacy analysis for the GATHER2 study at the 12-month time point, without waiting for the full 24-month data package, which we would collect after submitting for marketing approval and use to supplement our applications for marketing approval while they are pending. We have designed our GATHER2 trial to meet these requirements, which, as we understand them, and if data from the GATHER2 trial are positive, will permit us to seek marketing approval for Zimura in GA in the United States and potentially the European Union. Since receiving the 12-month results from the GATHER1 trial, we have not had an end of phase 2 or other formal meeting with either the FDA or the EMA and we may not do so before receiving results from the GATHER2 trial and submitting our applications for marketing approval. In addition, we have been engaging with various regulatory authorities, including competent national authorities in Europe, during the GATHER2 trial, and expect to continue engaging with regulatory authorities, including with the FDA as part of the fast track program. We may receive feedback that is not consistent with our expectations, including potential disagreements by the EMA and other regulatory authorities with what we are understand are the requirements of the FDA. Regulatory authorities may require us to enroll additional patients, collect additional safety data, conduct additional trials or take other actions, which would require us to revise our development plans for Zimura, including potentially changing the design of the GATHER2 trial, increase the costs of our Zimura clinical programs and delay our expected timelines. In addition, because of the COVID-19 pandemic or other reasons, we may experience a higher than anticipated rate of dropouts and missed visits and treatments in our GATHER2 trial, which could result in our not having adequate safety data for a sufficient number of patients to obtain marketing approval in GA, even if the primary endpoint is met and the results from the GATHER2 trial are otherwise positive.
Furthermore, our previous and ongoing Zimura clinical trials have evaluated Zimura dosing levels and regimens that we have studied only in cohorts consisting of a small number of patients. This approach may increase the risk that patients in our ongoing trials experience adverse events and/or serious adverse events (either ocular, systemic or both) that we have not observed or at rates that we have not observed in prior trials. Although we have not observed any adverse events or serious adverse events attributable by the investigators to the drug product in our GATHER1 trial, we may become aware of safety concerns as we analyze individual patient level data in our GATHER1 trial, and they may manifest in our STAR trial, in our GATHER2 trial or in any other subsequent clinical trials we or a potential collaborator may undertake for Zimura. When we follow patients for a longer period of time or collect safety data from a greater number of patients, we may observe safety events that we have not previously observed. For a further discussion of the safety risks in our trials, see the risk factor herein entitled "If serious adverse or unacceptable side effects are identified during the development of our product candidates, we may need to abandon or limit our development of such product candidates."
Because the primary efficacy endpoint and the statistical analysis plan we would expect to use to analyze efficacy data for our GATHER2 trial are similar to those of the GATHER1 trial, any disagreements by the FDA, EMA or other regulatory authorities with GATHER1 will likely affect GATHER2 as well. Our ongoing clinical trials and any future clinical trials for Zimura that we or a potential collaborator may undertake may fail to demonstrate sufficient safety or efficacy to justify further development or to ultimately seek or obtain marketing approval. Any negative results from our ongoing or any other future clinical trials for Zimura could adversely affect our business and the value of your investment in our company.
We have no unmasked clinical data regarding the safety and efficacy of Zimura as a treatment of STGD1. The dropout rate or patients with missing visits may reduce the number of patients from whom we can collect and analyze data from STAR. We may not be able to recruit additional patients for this trial in line with our expectations.
We have no unmasked clinical data regarding the safety and efficacy of Zimura as a treatment for STGD1. As STGD1 is an orphan indication, to our knowledge there is only very limited natural history data currently available regarding the variability of our planned primary efficacy endpoint in the STGD1 patient population we enrolled in this trial. Moreover, because Stargardt disease, like GA, is a degenerative disease, and in many cases, the rate of degeneration is slow, and because we are seeking to slow the progression of degeneration with Zimura, and not necessarily to reverse prior degeneration or restore visual function, patients participating in our STAR trial, who are generally younger and may experience vision loss that is more subtle than patients with GA or other forms of AMD, may not perceive a benefit from continuing to participate and therefore may drop out of this trial or miss scheduled visits and treatments. This risk is particularly magnified during the COVID-19 pandemic, which may cause our patients to voluntarily or involuntarily drop out of the trial or miss scheduled visits and treatments in greater numbers than before. Although we and the investigators and their staffs take efforts to encourage continued patient participation, the dropout rate may exceed our expectations. A higher than expected dropout rate would reduce the number of patients from whom data is available for analyzing the primary endpoint for this trial. Given the information above, our STAR trial could be underpowered to demonstrate a potential clinical benefit for Zimura in STGD1 with statistical significance.
We have decided to enroll approximately 25 additional patients in this trial, with the goal of enrolling a total of approximately 120 patients. This change to the trial will increase the costs associated with this trial and delay the timelines for
77
receipt of data from this trial. We believe an expanded trial could allow us to collect additional data regarding the effect of Zimura on STGD1 patients and help us mitigate the risks from additional patient dropouts and missed visits; however, these expectations may prove to be incorrect. Patient recruitment may take longer or cost more than we would expect.
The COVID-19 pandemic has affected and may continue to affect the initiation and conduct of our clinical trials, including the recruitment and retention of patients for our GATHER2 and STAR clinical trials. It may have long-lasting effects on the conduct of clinical trials, which can make our ongoing and any future trials more difficult, costly or time consuming.
Our GATHER1, GATHER2 and STAR trials involve sites located across the United States and in many countries outside the United States. In early 2020 after the start of the COVID-19 pandemic, we were in the process of completing patient visits for our GATHER1 trial and those of the initially enrolled patients in the STAR trial, and we were conducting startup activities for the GATHER2 trial. We have made a number of changes to the operations of our clinical trials as a result of the COVID-19 pandemic, its effects on current and prospective participating patients, and various governmental and other measures to control the pandemic. As the COVID-19 pandemic evolves, we may make further changes to how we conduct our ongoing and any future clinical trials.
Patient enrollment, missed patient visits and patient retention remain key risks for our clinical trials. Due to the COVID-19 pandemic, we delayed the initiation of patient enrollment for the GATHER2 trial from March 2020 to June 2020. Even though we are continuing to enroll patients in the GATHER2 and STAR trials, we are doing so cautiously in light of the health and safety measures put into place at various clinical trial sites. We may choose to or be required to slow down or stop patient enrollment in certain geographies due to the COVID-19 situation and any governmental measures taken in response. Patients, in turn, may be reluctant to enroll in clinical trials or to maintain their scheduled visits and treatments once enrolled due to their fears of visiting clinical trial sites or ongoing restrictive measures requiring social distancing or limiting travel. These concerns may particularly apply to GA patients, many of whom are elderly and therefore at a higher risk for COVID-19 and other diseases than the general population.
For patients who are enrolled in our trials, the COVID-19 pandemic may cause them to miss study visits or drop out in greater numbers than expected, which could affect our ability to complete our trials and obtain data in accordance with our expectations. Compared to the generally elderly patients in our GATHER2 trial, the patients in the STAR trial are generally younger and have work and family commitments, which may cause them to miss more visits or drop out in greater numbers. In addition to the risks posed by increased patient dropouts, if patients miss scheduled visits in greater numbers as a result of the pandemic, especially if a patient misses consecutive visits, it may affect our ability to draw meaningful conclusions from the clinical data. We are aware that a number of patients initially enrolled in the STAR trial missed consecutive visits during the early months of the COVID-19 pandemic. We do not know yet whether the number of missed visits will increase or decrease among the newly enrolled patients in the STAR trial or among the patients in the GATHER2 trial, and whether and to what extent missed visits may impact the results of the trials, especially since we are masked to the data until the conclusion of the trials. The duration of the GATHER2 and STAR trials, at 24 months and 18 months, respectively, plus time for recruiting patients, makes them more likely to be affected by any subsequent waves of the COVID-19 pandemic.
The COVID-19 pandemic has caused many of our clinical trial sites and competent health authorities and ethics committees in certain countries to reduce their staff and operations. This reduction in operations has resulted in delays to the approval of and the site activation process for the GATHER2 trial in certain geographies. As we continue to add clinical trial sites to the GATHER2 trial, the progress of site activation will depend on the local situation in each specific geography. In addition, many sites are focusing on more urgent matters rather than clinical trials, which may delay their ability to recruit patients. Recently, a number of our clinical trial sites have been scaling back their operations because of recent surges in COVID-19 cases or new lockdown measures being imposed. Shortages of vaccines, personal protective equipment and other supplies for the prevention of COVID-19 may cause our clinical trial sites to further scale back the number of staff on site and other operations, and may also cause prospective or enrolled patients to avoid clinical trial visits.
In addition to the disruptions to the operations of many clinical trial sites, the COVID-19 pandemic affected our monitoring and audit operations, for example, by requiring remote monitoring, remote source document verification and remote auditing in many instances. Some countries prohibit or limit remote source document verification due to privacy and other concerns. Because of privacy and other concerns with remote auditing, we have experienced difficulties and delays in performing audits on most of our clinical trial sites. Although we do not believe the COVID-19 pandemic has materially affected the robustness of our data verification process for the GATHER1 trial, we may find data verification discrepancies as we continue to evaluate the individual, unmasked patient level data from the GATHER1 trial. This risk may also affect our data verification processes for the STAR and GATHER2 trials.

Gene therapy is an emerging field of drug development that poses many scientific and other risks. As a company, we have only limited prior experience in gene therapy research and manufacturing and no prior experience in gene therapy clinical development. Our lack of experience and the limited patient populations for our gene therapy programs may limit our ability to be successful or may delay our development efforts.
Gene therapy is an emerging field of drug development with only two gene replacement therapies having received FDA approval to date. Our gene therapy research and development programs, which we decided to undertake based on a review of a limited set of preclinical data, are still at an early stage. Even with promising preclinical data, there remains several areas of drug development risk, including translational science, manufacturing materials and processes, safety concerns, regulatory pathway and clinical trial design and execution, which pose particular uncertainty for our programs given the relatively limited development history of, and our limited prior experience with, gene therapies. Furthermore, the medical community's understanding of the genetic causes of many diseases continues to evolve and further research may change the medical community's views on what therapies and approaches are most effective for addressing certain diseases.
For example, our IC-100 product candidate, which we are developing for RHO-adRP, has a mechanism of action that suppresses the expression of endogenous rhodopsin and seeks to replace it with a healthy version of rhodopsin. Patients with autosomal dominant conditions, such as RHO-adRP, have one healthy allele and one mutant disease-causing allele. For patients with RHO-adRP, although the rhodopsin produced by the mutant allele is generally toxic, leading to retinal degeneration, the rhodopsin produced by the healthy allele supports, and may be necessary for, the patient's existing vision. IC-100 may suppress the expression of all endogenous rhodopsin, whether expressed from the healthy or the mutant allele. Treatment with IC-100 may fail to suppress a sufficient amount of the toxic mutant allele or may fail to replace the rhodopsin expressed by the healthy allele to a sufficient degree. Although we believe, based on preclinical experiments in a canine model of RHO-adRP, that IC-100 will restore rhodopsin production to a level sufficient to maintain vision, we will not know this to be the case until we obtain human clinical data regarding IC-100's effect in this patient population.

Moreover, while there are more than 200 known mutations to the BEST1 gene, the different types of mutations and their association with various BEST1-related IRDs are still not well-understood. Our product candidate for these diseases, IC-200, may only be effective in treating retinal diseases associated with certain mutations in the BEST1 gene and not other mutations, especially if the mutation is associated with the production of a toxic protein. Additionally, we decided to in-license and pursue the development of IC-200 based on results observed in an autosomal recessive canine disease model. A majority of humans with BEST1-related IRDs, however, have the autosomal dominant form of the disease, commonly referred to as Best disease. If we choose to develop IC-200 for this patient population, using a construct previously studied in an autosomal recessive canine disease model, this approach may ultimately prove ineffective.
For our miniCEP290 program and other minigene programs, we are sponsoring research using a novel approach that is largely untested and presents various scientific and regulatory risks. To date, all the data generated for our miniCEP290 program are in a newborn mouse model for LCA10, and we do not know whether the effect we observed with these minigenes in mice will be replicated in other animals or humans. Furthermore, minigenes result in the expression of a protein that differs from the naturally occurring protein. The protein expressed by the minigene may have physiological effects, including toxic effects, that are not yet known. Because of the novelty of minigenes, the medical community's and regulators' receptiveness to this approach remains unknown. Our sponsored research may not fully elucidate all of the physiological risks associated with a particular minigene and the associated expressed protein. For these and other reasons, promising minigene candidates that emerge from our sponsored research programs with UMMS may not succeed in later stage preclinical and clinical development.
We have particularly focused on AAV gene therapy, as AAV vectors are relatively specific to retinal cells and their safety profile in humans is relatively well-documented as compared to other delivery vehicles and gene therapy technologies currently in development. However, AAV has a number of drawbacks, including its small packaging capacity: an AAV vector can hold only up to approximately 4,700 base pairs of DNA, whereas the genes that are associated with a number of diseases, such as LCA10, Stargardt disease and Usher 2A, exceed that size. Although AAV is the most commonly used vector in ocular gene therapy today, it may prove to pose safety risks that we are not aware of and other vector forms, such as retroviral or lentiviral and non-viral based vectors, or gene editing approaches, may prove to be safer and more effective.
Although we believe gene therapy is a promising area for retinal drug development, our gene therapy research and development experience is limited to only a limited number of personnel hired to supervise our outside service providers. In pursuing this new technology, we have begun to establish our own gene therapy technical capabilities, but we will need to continue to build those capabilities by either hiring internally or seeking assistance from outside service providers. We believe that gene therapy is an area of significant investment by biotechnology and pharmaceutical companies and that there may be a scarcity of talent available to us in these areas. If we are not able to expand our gene therapy capabilities, we may not be able to develop in the way we intend or desire, IC-100, IC-200 or any promising product candidates that emerge from our miniCEP290
79
program or our other collaborative gene therapy sponsored research programs, which would limit our prospects for future growth.
We have not previously conducted any clinical development involving gene therapies. As we prepare for the potential initiation of our first gene therapy clinical trial, we will need to build our internal and external capabilities in designing and executing a gene therapy clinical trial. There are many known and unknown risks involved in translating preclinical development of gene therapies to clinical development, including selecting appropriate endpoints and dosage levels for dosing humans based on preclinical data. We are planning to meet with the FDA to discuss our selected doses for a first-in-human clinical trial for IC-100; the FDA may disagree with our selected doses or require us to conduct additional preclinical studies, which may delay our timelines for IC-100. In particular, many of the indications for which we are pursuing our gene therapy programs have limited natural history data and limited number of therapies in clinical development, which may make selecting an appropriate endpoint difficult. Furthermore, our gene therapy programs are targeting orphan diseases with relatively small populations, which limits the pool of potential patients for our gene therapy clinical trials. Because gene therapy trials generally require patients who have not previously received any other therapy for the same indication, we will also need to compete for the same group of potential clinical trial patients with our competitors who are also developing therapies for these same indications. If we are unable to initiate and conduct our gene therapy clinical trials in a manner that satisfies our expectations or regulatory requirements, the value of our gene therapy programs may be diminished.
For a further discussion of the risks associated with the manufacturing of gene therapy products, see the risk factor herein entitled "The manufacture of gene therapy products is complex with a number of scientific and technical risks, some of which are common to the manufacture of drugs and biologics and others are unique to the manufacture of gene therapies. We have limited experience with gene therapy manufacturing and are dependent on our third-party contract manufacturers and sole source suppliers".
Our development of IC-500 is also based on a novel mechanism of action that is unproven and poses a number of scientific and other risks.
IC-500, our selected product candidate from our HtrA1 inhibitor program, is in preclinical development. There are no FDA or EMA approved products that utilize HtrA1 inhibition as a mechanism of action for treating ophthalmic diseases, including GA and other age-related retinal diseases for which we may develop IC-500, and this mechanism of action may not prove safe and effective for these diseases. Although other companies are pursuing HtrA1 inhibition as a strategy for treating retinal diseases, including Genentech in an ongoing Phase 2 clinical trial in GA, to date, there is limited published clinical data regarding the safety and efficacy of HtrA1 inhibition in the target patient population. We are also aware that Genentech recently commenced a clinical trial to assess the long-term safety and tolerability of its monoclonal antibody HtrA1 inhibitor. We made the decision to acquire this program in 2018 based on our interpretation of the scientific literature and rationale for this potential target that suggest an association between HtrA1 and the risk for AMD, as well as a limited set of preclinical data generated by Inception 4 prior to the acquisition. We note, however, the HtrA1 gene is in the same region of the 10q26 chromosome as the age-related maculopathy susceptibility 2, or ARMS2, gene. The ARMS2 and HtrA1 genes are linked, and variants in, or expression of, the ARMS2 gene may also be associated with the risk for AMD. The risk for AMD associated with ARMS2 may ultimately prove to be greater than the risk associated with HtrA1. In addition, even though genetic and histologic findings correlate HtrA1 with AMD, the development and progression of AMD may not be affected by HtrA1. Our hypothesis that targeting inhibition of HtrA1 may be a safe and effective method of treating AMD may ultimately be incorrect, which would likely adversely affect the value of IC-500 and its continued development.
To our knowledge, there are no suitable animal models for GA or dry AMD. This absence of a suitable animal model makes designing a proof of concept study to assess the preclinical efficacy of IC-500 difficult. To date, we have not yet generated any preclinical data of IC-500 in animal studies. In addition, we have not had any formal or informal interactions with the FDA or other regulatory authorities regarding our preclinical development plans for IC-500. We do not know whether the FDA or other regulatory authorities will accept any preclinical proof of concept study we may propose, or other aspects of our preclinical development plans for IC-500. The FDA may require us to change our plans or conduct additional studies, which would increase our costs and delay our timelines.
If serious adverse or unacceptable side effects are identified during the development of our product candidates, we may need to abandon or limit our development of such product candidates. There are a number of known safety risks associated with our product candidates, including gene therapies, and currently unknown safety issues may arise during development.
If any of our product candidates are associated with serious adverse events or undesirable side effects in preclinical studies or clinical trials or have characteristics that are unexpected, we may need to abandon their development or limit development to certain uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent,
80
less severe or more acceptable from a risk-benefit perspective. Many drugs that initially showed promise in clinical or earlier stage testing have later been found to cause side effects that prevented further development. Safety issues may arise due to reasons unrelated to the study drug, such as issues with the injection procedure or the syringes or needles being used.
In our completed clinical trials for Zimura, we have observed only a single adverse event, mild subcapsular cataract, from our OPH2000 trial, assessed to be drug-related by participating investigators. Although not reported as related to Zimura by investigators, we observed an increase in the number of investigator-reported cases of CNV in the Zimura treatment groups in the GATHER1 trial as compared to the sham control groups. For the GATHER2 trial, because we are asking investigators to perform monthly OCT imaging and to submit cases where patients experience a decrease in visual acuity of five or more ETDRS letters between successive visits to the independent reading center for confirmation by multi-modal imaging, in addition to the cases the investigator suspects to be CNV, we may observe a higher rate of CNV cases in the GATHER2 trial, including, potentially in the Zimura 2 mg treatment group as compared to the sham group. We have no unmasked data regarding the safety, tolerability or efficacy of Zimura administered for the treatment of STGD1. We have no human data regarding IC-100, IC-200 or IC-500.
Our clinical trials for Zimura involve dosing regimens that we have not studied extensively, which may increase the risk that patients in these trials experience adverse events and/or serious adverse events (either ocular, systemic or both) that we have not observed or at rates that we have not observed in prior trials. For example, although we view the rate of CNV incidence in the Zimura treatment groups, as compared to the corresponding sham control groups, as acceptable and within the range observed in other clinical trials of complement inhibitors in development for GA, the FDA, EMA, other regulatory authorities, treating physicians or patients may not agree, concluding that Zimura may increase the risk of patients developing CNV to an unacceptable degree. Moreover, our clinical trials for Zimura involve multiple intravitreal injections over an extended period of time and, as such, may involve risks regarding multiple and chronic intravitreal injections. For these reasons, there may be, among others, an increase in the rates of intraocular infections, or endophthalmitis, intraocular pressure, glaucoma, retinal tears, cataracts, retinal detachment, intraocular inflammation, retinal and/or choroidal circulation compromise, or hospitalizations in patients who receive Zimura. Although the safety profile of Zimura remained favorable at month 18 in our GATHER1 trial, we may encounter unknown safety issues as we analyze the unmasked individual patient level data. An unforeseen or unexpected safety event, or any safety finding that is inconsistent with our prior experience with Zimura, from any of our clinical trials for Zimura, including from the GATHER2 trial during which we will follow patients and collect safety data over 24 months, may impact our ability to continue to develop Zimura or the long-term viability of Zimura as a potential treatment for GA, STGD1 or any other indication for which we may seek to develop Zimura.
As HtrA1 inhibition is a novel treatment approach for treating ocular disease, this treatment approach may present potentially unknown safety risks when tested in clinical trials that could not have been anticipated based on preclinical studies, including the toxicology studies we are planning. In addition, if we are successful in formulating IC-500, we intend to administer IC-500 by intravitreal injection, which poses the same safety risks outlined above with respect to intravitreal injections of Zimura.
In addition, there are several known safety risks specific to gene therapy, including inflammation resulting from a patient's immune response to the administration of viral vectors and the potential for toxicity as a result of chronic exposure to the expressed protein. Managing a host body's immune response to introduced viral vectors has been and remains a challenge for gene therapies. For AAV gene therapy, "vector shedding," or the dispersal of AAV vectors away from the target tissue to other parts of the body, which can trigger a more serious and extensive immune response, is a known safety issue. Although subretinal injection, which is the method often used to administer retinal gene therapies, helps to control vector shedding beyond the eye, subretinal injection is a surgical procedure that requires significant skill and training for the administering surgeon and involves its own risks separate from the gene therapy vectors, including the risk of retinal detachment. The margin for error with subretinal injections is extremely low and there are a limited number of retinal surgeons with experience in performing subretinal injections in the eye. In order to generate useful clinical data for gene therapy clinical trials, one or more retinal surgeons must repeat the same subretinal injection procedure in multiple patients with consistency across patients and surgeons. In addition, in order to avoid accelerating damage to a patient's retina, subretinal injection for RHO-adRP patients in particular must be conducted under extremely low light levels using infrared technology, further complicating the surgical procedure. In the event that we progress into clinical development with IC-100, IC-200 or any other gene therapy product candidate we may in-license or acquire, we may experience delays or other challenges for our gene therapy development programs as a result of safety issues.
In addition to the currently known safety risks, there may be unknown risks to human health from gene therapies. Because gene therapy involves the introduction of concentrated quantities of AAV, as well as the introduction of persistent foreign genetic material into the human body, any safety risks may not manifest until much later, if at all. Gene therapies have only recently been used in the treatment of human diseases and the scientific and medical understandings of safety or other risks
81
to humans continue to evolve. The safety profile of minigenes and their associated proteins in humans remains largely unknown. If gene therapies prove to be unsafe for humans, we likely will need to curtail or eliminate our gene therapy development programs or gene therapy products in commercialization, if any.
We do not have any internal manufacturing capabilities and use third parties to manufacture our product candidates on a contract or purchase order basis. We may encounter manufacturing issues that could cause delays in our development programs or increase costs. We may experience delays in regulatory approval of our product candidates if we or our contract manufacturers do not satisfy applicable regulatory requirements. If any of our product candidates is approved, a manufacturing issue could result in product shortages, which could impair our ability to commercialize our products and generate revenue.
We do not have internal manufacturing facilities and use or plan to use outside contract manufacturers to manufacture Zimura, IC-100, IC-200, IC-500 and any other product candidates that we may acquire or in-license. We have a limited number of personnel hired to supervise these outside vendors. The manufacturing processes for our product candidates are technically complex. Problems with developing, executing or scaling up the manufacturing process, even minor deviations from the established process, could result in product defects or manufacturing failures that result in lot failures, product recalls, product liability claims, insufficient inventory or delays to our programs. We may encounter problems achieving adequate quantities and quality of clinical-grade materials that meet FDA, EMA or other applicable standards or specifications with consistent and acceptable production yields and costs.
In addition, in order to manufacture and supply any of our product candidates for later-stage clinical trials or on a commercial scale in the future, we will need to increase our manufacturing personnel and bolster our quality control and quality assurance capabilities. We may encounter problems hiring and retaining scientific, manufacturing and quality assurance and control personnel needed to oversee our contract manufacturers, which could result in delays in our production or difficulties in maintaining compliance with applicable regulatory requirements. As our contract manufacturer scales up manufacturing of any product candidate, we may encounter unexpected issues relating to the manufacturing processes or the quality, purity or stability of the product, and we may be required to refine or alter our manufacturing processes to address these issues, or may need to use an alternative manufacturer. Resolving these issues could result in significant delays and may result in significantly increased costs. If we underestimate the demand for an approved product, given the long lead times required to manufacture or obtain regulatory approvals for our products, we could potentially face commercial drug product supply shortages. If we experience significant delays or other obstacles in producing any approved product at commercial scale, our ability to market and sell any approved products may be adversely affected and our business could suffer.
The manufacturing processes and the facilities of our third-party manufacturers are subject to inspection and approval by the FDA, referred to as a pre-approval inspection, before we can commence the commercial sale of any approved product candidate, and thereafter on an ongoing basis. None of our third-party manufacturers have undergone a pre-approval inspection by the FDA for Zimura or any of our other product candidates. Failure by our third-party manufacturers to pass such inspections and otherwise satisfactorily complete the FDA approval regimen with respect to our product candidates may result in delays in the approval of our applications for marketing approval, as well as regulatory actions such as the issuance of FDA Form 483 notices of observations, warning letters or injunctions or the loss of operating licenses. If any of our third-party manufacturers are found to have delayed, denied, limited or refused a drug inspection, our drug substance or drug product could be deemed adulterated. Based on the severity of the regulatory action, our clinical or commercial supply of drug substance or drug product could be interrupted or limited, which could have a material adverse effect on our business.
Any problems in our manufacturing process or our third-party contract manufacturers’ facilities could make us a less attractive collaborator for potential collaborations, including with larger pharmaceutical companies and academic research institutions. Problems in our manufacturing process or facilities also could restrict our ability to meet market demand for our products.
For a further discussion of the risks associated with our reliance on third-party manufacturers, including the effects of the COVID-19 pandemic on our third-party manufacturers, see the risk factor herein entitled, "We contract with third parties for the manufacture of and for providing starting materials for our product candidates for preclinical development activities and clinical trials and expect to continue to do so in the future. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or products, which could delay, prevent or impair our development or commercialization efforts."
82
Our experience manufacturing Zimura is limited. As we conduct our GATHER2 trial and our expanded STAR trial and plan for potential commercialization of Zimura, we and our third-party manufacturers will need to complete several activities to ensure the continued supply of drug product for these trials and adequate preparations to support potential future commercial supply of Zimura. Any delay or failure in completing these activities could cause delays in the development of Zimura or its potential approval or could result in inadequate clinical or commercial product supply.
In order to obtain and maintain regulatory approval for Zimura, our third-party manufacturers will be required to produce Zimura drug substance with consistent quality and to execute fill/finish services on a repeated basis and document their ability to do so. In order for us to successfully commercialize Zimura, if approved, our manufacturers also need to be able to produce quantities at a commercial scale. If our third-party manufacturers are unable to satisfy these requirements, our business would be materially and adversely affected. To date, we have not yet scaled up the manufacturing process for Zimura beyond the scale used for developmental clinical batches, nor have we validated the manufacturing process.
In early 2017, we completed the small scale manufacture of multiple batches of Zimura drug substance that we are using to support clinical drug supply for the GATHER2 trial and the expanded STAR trial. Although we believe we have adequate Zimura drug substance for the GATHER2 trial and the expanded STAR trial, this supply may not be sufficient for our needs over the duration of the trials or for any additional trials we may conduct. We have initiated activities in preparation for the scale-up and validation of the manufacturing process for Zimura drug substance with a new manufacturer, with the goal of assessing whether this manufacturer can produce Zimura drug substance at an adequate scale for future potential commercial use. If this manufacturer is successful, we intend for this manufacturer to be our primary supplier of Zimura drug substance. However, this manufacturer may not be successful because of any number of reasons. We also recently engaged our historical contract manufacturer for Zimura drug substance, Agilent Technologies, Inc., or Agilent, for scale-up and validation activities. Depending on the success of the scale-up activities by the new manufacturer, we may use either this new manufacturer, Agilent or both for future supply of Zimura drug substance, which may increase our costs and delay our timelines. In addition, regardless of which manufacturer we use, we will need to demonstrate that the drug substance produced through the scaled-up process is analytically comparable to the drug substance we are currently using. If we are unable to demonstrate that the Zimura drug substance produced through the scaled-up process is analytically comparable to the Zimura drug substance we are currently using, including as a result of not having the appropriate assays to demonstrate analytical comparability, our timelines to complete the development of and seek regulatory approval for Zimura would be impacted.
In 2020, we engaged a contract manufacturer to provide us with additional supply of finished Zimura drug product to support our needs for the GATHER2 trial and the expanded STAR trial. We expect that this contract manufacturer will be able to supply sufficient finished Zimura drug product for these two clinical trials. However, we may face issues with releasing batches of finished Zimura drug product from this contract manufacturer, or even if these batches can be successfully released, we may not have sufficient supply for our needs over the duration of these trials or for any additional trials we may conduct. In addition, we are planning to make a change to the existing vial used for Zimura drug product, which we believe may allow us to support a more efficient fill/finish operation at a commercial scale. We have been in discussions with our historical fill/finish manufacturer, Ajinomoto Bio-Pharma Services, or Ajinomoto, regarding its capacity to supply us with finished Zimura drug product with the new vial for potential commercial use. If Ajinomoto is unable to provide us and/or a potential collaborator with Zimura drug product for potential commercial use, we will need to use alternative suppliers, which may increase our costs and delay our timelines.
We order the PEG starting material used to make Zimura drug substance from a sole source third-party manufacturer outside the United States. We currently procure the supply on a purchase order basis and are planning to enter into a long-term supply agreement with this manufacturer for the PEG starting material. However, we may not be able to agree to terms or may need to agree to unfavorable terms in order to secure adequate supply. We are assessing this supplier's capacity to supply the PEG at the scale that we expect we will need for commercial manufacturing. If this supplier is unable to supply us the PEG in line with our expectations, we believe there are a limited number of alternative suppliers for this critical raw material, and if we need to use those suppliers, it could increase our costs and delay our manufacturing plans for Zimura.
Each of these activities is costly, time-consuming and uncertain in outcome. We may not be able to successfully scale up or validate our manufacturing process for Zimura, demonstrate analytical comparability of the Zimura drug substance manufactured through the scaled up process with the previously manufactured Zimura drug substance, or establish the long-term stability of the Zimura drug product stored in the new vial container. The new manufacturers we have engaged or may engage in the future have not had previous experience with Zimura and there may be issues with technology transfer. We may need to perform additional work beyond what we currently plan to establish manufacturing and analytical capabilities sufficient to obtain regulatory approval of our manufacturing process for Zimura and to support potential commercial operations. If any of the foregoing events occur, it could result in delays or increased costs to support our future development and commercialization
83
of Zimura, even if we successfully complete any required clinical trials for Zimura and obtain sufficient and favorable safety and efficacy data.
Some of the standards of the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use, which establishes basic guidelines and standards for drug development in the United States, the European Union, Japan and certain other countries, do not apply to oligonucleotides, including aptamers. As a result, there are limited established generally accepted manufacturing or quality standards for the production of oligonucleotides such as Zimura. The lack of uniform manufacturing and quality standards among regulatory agencies may delay regulatory approval of Zimura. Furthermore, there are a limited number of contract manufacturers with experience manufacturing oligonucleotides, which may limit our ability to find and use alternative manufacturers.
The manufacture of gene therapy products is complex with a number of scientific and technical risks, some of which are common to the manufacture of drugs and biologics and others of which are unique to the manufacture of gene therapies. As previously disclosed, we identified an issue with one of the starting materials used to manufacture IC-100, which delayed our timelines for that program. We have limited experience with gene therapy manufacturing and are dependent on our third-party contract manufacturers and sole source suppliers.
Gene therapy drug products are complex and difficult to manufacture. We believe that the high demand for clinical gene therapy material and a scarcity of potential contract manufacturers may cause long lead times for establishing manufacturing capabilities for gene therapy drug development activities. Even after a manufacturer is engaged, any problems that arise during manufacturing, including during process development and cGMP manufacturing, may result in unanticipated delays to our timelines, including delays attributable to securing additional manufacturing time slots. In 2020, we experienced delays to our cGMP manufacturing activities for IC-100 and IC-200 because of a number of manufacturing issues at our CDMO. There may also be long lead times to manufacture or procure starting materials such as cell banks or plasmids. In particular, plasmids and other starting materials for gene therapy manufacture are usually sole sourced, as there are a limited number of qualified suppliers. The progress of our gene therapy programs is highly dependent on these suppliers providing us or our contract manufacturers with the necessary starting materials that meet our requirements in a timely manner. A failure to procure or a shortage of necessary starting materials likely would delay our manufacturing and development timelines.
As previously disclosed, we identified an issue with one of the starting materials used for our manufacturing process for IC-100. That issue caused us to delay our cGMP manufacturing run at our CDMO, and we had to reschedule the run for a later date based on the CDMO's availability. The supplier has since provided new starting materials for our rescheduled cGMP manufacturing run. Although we believe the new starting materials met our expectations and the manufacturing of the cGMP batch has been successful, we may find unexpected issues as we complete testing and release of the batch. If there are issues with the new starting materials or the produced batch, our timelines and the future development of IC-100 could be adversely affected.
A number of factors common to the manufacturing of biologics and drugs could also cause production or quality issues for gene therapies, including raw material or starting material variability in terms of quality, consistency in cell growth, productivity or cell line stability issues, product and process impurities, material shortages of any kind, shipping, distribution, storage and supply chain failures, cell culture contamination, equipment malfunctions, operator errors, facility contamination, labor problems, natural disasters, disruption in utility services, terrorist activities, epidemics and pandemics, or acts of god that are beyond our or our contract manufacturer's control. It is often the case that early stage process development is conducted with materials that are not manufactured using cGMP starting materials, techniques or processes and which are not subject to the same level of analysis that would be required for clinical grade material. We may encounter difficulties in translating the manufacturing processes used to produce research grade materials to cGMP compliant processes, and any changes in the manufacturing process may affect the safety and efficacy profile of our product candidates. In particular, for IC-100 and IC-200 we and our contract manufacturers have developed our own manufacturing processes, which differ from those originally used by our university collaborators, for example, by using different starting materials and analytical methods. Our manufactured materials may not match the safety and efficacy profile of those used by the universities.
Because manufacturing for early stage research is often done under different conditions, using different starting materials and manufacturing systems and done on a smaller scale than what is required for manufacturing for clinical supplies, we may face challenges producing the same product as that produced by the manufacturing processes used by our licensors and other academic collaborators and scaling up the new manufacturing processes as necessary to support supply for clinical trials. In order to progress the development of IC-100, IC-200 or any other gene therapy product candidate we may in-license or acquire, we have devoted and will need to continue to devote significant time and financial resources to establishing manufacturing processes that are sufficient for IND-enabling preclinical toxicology studies as well as clinical supplies. If we are not able to establish gene therapy manufacturing or related processes in a manner required for further development of our gene
84
therapy product candidates, our development plans may be delayed and our business may be materially harmed. In particular, although our CDMO produced cGMP batches for each of IC-100 and IC-200, we may encounter issues with releasing any of those batches, which could hamper us from filing an IND and initiating a human clinical trial for that product candidate.
An important part of manufacturing drug products is performing analytical testing. Analytical testing of gene therapies involves tests that are more complex in scope and take a longer time to develop and to conduct as compared to those used for traditional drugs. We, our contract manufacturers and our contract research organizations need to expend considerable time and resources to develop assays and other analytical tests for our gene therapy product candidates, including assays to assess the potency of our gene therapy product candidates. Some assays need to be outsourced to specialized testing laboratories. Even when assays are developed, they need to be further tested, qualified and validated, which may take substantial time and resources. Because of the lagging nature of analytical testing, we may proceed with additional manufacturing and other development activities without having first fully characterized or released our manufactured materials. If the results of the testing fail to meet our expectations or applicable requirements, we may need to delay or repeat certain manufacturing and development activities.
We are in the early stages of establishing manufacturing capabilities for IC-500. We may need to conduct additional process development and formulation development activities.
Before we can commence IND-enabling studies for IC-500, we will need to conduct process development and formulation development to determine whether we can identify a viable manufacturing process for and formulate IC-500 for intravitreal administration that is safe to advance into preclinical studies and, depending on the outcome of such studies, into clinical trials. For example, as part of formulation development, we will need to determine which inactive formulation components should be used in the preparation of IC-500, and derive a preparation that includes an adequate amount of drug substance with the necessary inactive ingredients to achieve the desired safety and efficacy profile for intravitreal injection into the eye.
We are working with a CDMO to conduct process development, scale up and cGMP manufacturing of the drug substance for IC-500 for preclinical toxicology studies and early-stage clinical trials. We are working with another CDMO to conduct formulation development activities for the drug product for IC-500. Our contract manufacturers have developed a manufacturing process for IC-500 drug substance and a formulation of this produced drug substance. However, we have not yet tested this formulation in any preclinical animal studies; the results of these studies may require us to refine or change our manufacturing process or conduct additional formulation development activities. We are in the process of engaging a contract manufacturer to manufacture finished drug product for clinical supply. Manufacturing, including process development, formulation development and drug product manufacturing, can be costly and time-consuming and our anticipated timelines for the development of IC-500 may be delayed. If we are unable to successfully manufacture and formulate IC-500 in line with our expectations, we may switch to a backup HtrA1 inhibitor or cease developing our HtrA1 inhibitor program altogether.
We face substantial competition, which may result in others developing or commercializing products before or more successfully than we do.
The development and commercialization of new drug products is highly competitive. We face competition with respect to our product candidates and other programs from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies, as well as generic and biosimilar companies, worldwide. Potential competitors also include academic institutions, government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and commercialization. Some of these competitive products and therapies are based on scientific approaches that are the same as or similar to our approach, and others are based on entirely different approaches. We also will face similar competition with respect to any product candidates that we may seek to develop or commercialize in the future.
Our business strategy includes a focus on developing transformative therapies for retinal diseases, including GA secondary to age-related macular degeneration and a number of orphan inherited retinal diseases. There are multiple companies pursuing the development of therapeutics targeting the complement pathway and gene therapy approaches for orphan and age-related retinal diseases. Some of them have better name recognition, more resources and a longer history of developing therapies than we do. Competition in this field is intense and especially for many inherited retinal diseases, there is a limited number of potential patients. If any of our competitors obtains FDA, EMA or other regulatory approval for their products more rapidly than we may obtain approval for ours, our competitors could establish a strong market position before we are able to enter the relevant market, which may significantly limit the commercial opportunity for our product candidates.
85
Our commercial opportunity could also be reduced or eliminated if one or more of our competitors develop and commercialize products that are more effective, safer, have fewer or less severe side effects, are more convenient to use or are less expensive than our product candidates. For example, the method of administration of Zimura, intravitreal injection, is commonly used to administer ophthalmic drugs for the treatment of severe diseases and is generally accepted by patients facing the prospect of severe visual loss or blindness. A therapy that offers a less invasive or less frequent method of administration, however, might have a competitive advantage over one administered by monthly intravitreal injections, depending on the relative safety of the other method of administration. Furthermore, our ability to compete may be affected in many cases by insurers or other third-party payors, particularly Medicare, seeking to encourage the use of less expensive or more convenient products.
Many of our competitors have significantly greater financial and human resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. Smaller and other early stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and enrolling patients for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our development programs. Our timelines may be delayed to the extent clinical trials conducted by our competitors are enrolling patients that would otherwise be eligible to participate in our trials at the same time we are seeking to enroll these patients, such as may be the case for the GATHER2 trial, for which a number of other companies have active clinical trials.
Based on publicly available information, we are aware of the following research and development programs that may be competitive with programs we are pursuing. Other competitive programs may exist of which we are not aware.
Competitive considerations for GA or dry AMD:
•We are aware that LumiThera, Inc. has a medical device using its LT-300 light delivery system, which is approved in the European Union for the treatment of dry AMD. In addition, there are a number of products in preclinical and clinical development by third parties to treat GA or dry AMD. In general, these product candidates can be categorized based on their proposed mechanisms of action. The mechanisms of action for these product candidates include complement system and inflammation suppression, visual cycle modulators, antioxidants and neuroprotectants, cell and gene therapies and vascular perfusion enhancers. We are aware that Alexion Pharmaceuticals, Inc., Annexon Inc., Apellis Pharmaceuticals, Inc., or Apellis, Applied Genetic Technologies Corporation, or AGTC, Biogen Inc., Gemini Therapeutics, Inc., Gyroscope Therapeutics, IONIS Pharmaceuticals, Inc. (in collaboration with Roche AG), Janssen Pharmaceuticals Inc. (which acquired its program through the acquisition of Hemera Biosciences, LLC), MorphoSys AG, NGM Biopharmaceuticals Inc. and Novartis AG each have complement inhibitors in development for GA or dry AMD, including, in the cases of Gemini Therapeutics, Gyroscope Therapeutics and Janssen Pharmaceuticals, complement inhibitor gene therapies and AGTC and Gemini Therapeutics each has a research program on complement factor H gene therapy. We believe that the most advanced of these programs is Apellis's pegylated, synthetic peptide targeting complement protein C3. In July 2020, Apellis announced that it had completed patient enrollment in its Phase 3 program with a total of 1,259 patients, and expects to announce top-line data from the trials in the third quarter of 2021. If Apellis's Phase 3 program for its C3 complement inhibitor product candidate is successful, it is likely that Apellis would obtain marketing approval for its product candidate in advance of when we could reasonably expect to obtain marketing approval for Zimura in GA or IC-500 in GA, if at all. Moreover, we are aware that several other companies, including Allergan Inc., Allegro Ophthalmics, LLC, Alkeus Pharmaceuticals Inc., Astellas Pharma Inc., Boehringer Ingelheim, EyePoint Pharmaceuticals, Inc., Lineage Cell Therapeutics, Inc., Roche AG and Stealth BioTherapeutics Corp., are pursuing development programs for the treatment GA or dry AMD using different mechanisms of action outside of the complement system, including Genentech, Inc. (an affiliate of Roche AG) and Gemini Therapeutics, which are pursuing HtrA1 inhibition as a mechanism of action. We believe that the most advanced HtrA1 inhibitor program in development is Genentech's monoclonal antibody HtrA1 inhibitor, which is currently being studied in a Phase 2 clinical trial.
Competitive considerations for Stargardt disease:
•There are a number of products in preclinical research and clinical development by third parties to treat Stargardt disease. We are aware that AGTC, Alkeus Pharmaceuticals, Inc., Beam Therapeutics Inc., Generation Bio Co., Kubota Vision Inc. (formerly Acucela), Lin BioScience, Inc., Nightstar Therapeutics plc (prior to its acquisition by Biogen), or Nightstar, ProQR Therapeutics N.V., or ProQR, and Spark Therapeutics each have research or development programs in Stargardt disease. Three of these programs, Alkeus, Kubota and Lin BioScience, are exploring the use of oral therapeutics, while AGTC, Nightstar and Spark are each using a gene therapy approach, Beam is using a base editing
86
approach, and ProQR is using an RNA based approach. Kubota’s product candidate, to which the FDA and the EMA granted orphan drug designation in August 2020, is in Phase 3 development while Alkeus’s product candidate is in Phase 2 development. In addition, several academic organizations have early stage programs in Stargardt disease.
Competitive considerations for RHO-adRP:
•We are aware that ProQR is developing an RNA-based therapeutic for RHO-adRP, for which it is currently conducting a Phase 1/2 clinical trial. Ocugen, Inc. is developing a gene therapy for RHO-adRP, for which the FDA granted orphan drug designation in July 2020. In addition, prior to its acquisition by Biogen, Nightstar had a preclinical AAV gene therapy program in RHO-adRP. 4D Molecular Therapeutics is developing an intravitreal gene therapy for RHO-adRP. Editas Medicine, Inc. is exploring a potential gene editing program in this disease. We are also aware that multiple academic institutions have early stage gene therapy development programs in RHO-adRP.
Competitive considerations for BEST1-related IRDs:
•We are aware that, prior to its acquisition by Biogen, Nightstar had a preclinical AAV gene therapy program for one or more BEST1-related IRDs.
Competitive considerations for LCA10:
•We are aware that Editas Medicine, Inc. has a gene editing program for LCA10, for which a Phase 1/2 clinical trial is ongoing, ProQR is developing an RNA-based therapeutic for LCA10 that is currently in Phase 2/3 development, Generation Bio Co. has a preclinical program that utilizes ceDNA technology to target LCA10 and Oxford Biomedica plc is developing a lentiviral gene therapy program for LCA10 that is in preclinical development. In addition, several academic institutions have preclinical programs in LCA10.
Competitive considerations for USH2A-related IRDs:
•There are a number of products in preclinical research and clinical development by third parties to treat USH2A-related IRDs. We are aware that ProQR is pursuing two RNA based approaches for different mutations causing Usher 2A, one of which is currently in Phase 1/2 clinical development and the other of which is in preclinical development. We are also aware that Editas Medicine, Inc. and Odylia Therapeutics are exploring potential programs in USH2A-related IRDs.
If we are unable to establish sales, marketing and distribution capabilities or enter into sales, marketing and distribution agreements with third parties, we may not be successful in commercializing any of our product candidates that we develop if and when any such product candidate is approved.
As a company, we have no experience in the sale, marketing or distribution of pharmaceutical products. We currently do not have any sales, marketing or distribution infrastructure or dedicated personnel. To achieve commercial success for any approved product, we must either develop a sales, marketing and distribution organization or outsource those functions to third parties. We expect that our commercial strategy for any of our product candidates, including whether to retain commercial rights and market and sell the product candidate ourselves or to utilize collaboration, distribution or other marketing arrangements with third parties, would be determined based on a variety of factors, including the size and nature of the patient population, the disease area, the particular indications for which the product is approved, the territories in which the product may be marketed and the commercial potential for such product candidate. We are developing Zimura and IC-500 for GA secondary to AMD, which is a condition affecting a relatively large number of individuals. In contrast, our gene therapy programs are currently being developed for orphan IRDs with a limited number of affected individuals. If any of our product candidates is approved, the size and nature of the affected patient population will be an important factor in our commercial strategy. In addition, our commercial strategy would vary depending on whether the disease is typically treated by general ophthalmology practitioners, specialists, such as retinal specialists, or sub-specialists, such as retinal specialists with particular expertise in IRDs, and the likely degree of acceptance of our product candidate by the relevant physicians in various markets.
There are risks involved with establishing our own sales, marketing and distribution capabilities. For example, recruiting and training a sales force is expensive and time consuming and could delay any product launch. If the commercial launch of a product candidate for which we recruit a sales force and establish marketing and distribution capabilities is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. This may be costly, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel.
87
Factors that may inhibit our efforts to commercialize our products on our own include:
•our inability to recruit and retain adequate numbers of effective sales and marketing personnel;
•the inability of sales personnel to obtain access to adequate numbers of physicians who may prescribe our products;
•the lack of complementary products to be offered by our sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product lines; and
•unforeseen costs and expenses associated with creating an independent sales and marketing organization.
There are also risks involved with having third parties perform sales, marketing and distribution services on our behalf. If we enter into arrangements with third parties to perform sales, marketing and distribution services, our product revenues and our profitability, if any, are likely to be lower than if we were to market, sell and distribute ourselves any products that we develop. In addition, we may not be successful in entering into arrangements with third parties to sell, market and distribute our product candidates or may be unable to do so on terms that are favorable to us. We likely will have little control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our products effectively. If we do not or are unable to establish sales, marketing and distribution capabilities successfully, either on our own or in collaboration with third parties, we would not be successful in commercializing our product candidates, if approved.
Even if any of our product candidates receives marketing approval, such product candidate may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success and the market opportunity for any of our product candidates may be smaller than we estimate.
The degree of market acceptance of any product candidate that we are developing or we may develop, if approved for commercial sale, will depend on a number of factors, including:
•efficacy and potential advantages compared to alternative treatments, including the existing standard of care;
•any restrictions in the label on the use of our products in combination with other medications or with certain devices;
•any restrictions in the label on the use of our products to or by a subgroup of patients, including, for example, for Zimura, if approved, restrictions on use of our product to patients with GA secondary to dry AMD (as opposed to GA secondary to any or all forms of AMD or other stages of AMD) or to patients with specific GA lesion characteristics, such as non-foveal GA, or for our gene therapy product candidates, if approved, restrictions on use of our product if a patient previously received another gene therapy product;
•for treatment regimens calling for multiple intravitreal injections on the same day, restrictions in the label imposing a waiting period in between intravitreal injections;
•our and any commercialization partner’s ability to offer our products at competitive prices;
•availability of governmental and third-party payor coverage and adequate reimbursement;
•increasing reimbursement pressures on treating physicians due to the formation of accountable care organizations and the shift away from traditional fee-for-service reimbursement models to reimbursement based on quality of care and patient outcomes;
•willingness of the target patient population to try new therapies and of physicians to prescribe these therapies, particularly in light of the existing available standard of care or to the extent our product candidates require invasive procedures for administration, such as subretinal surgery;
•prevalence and severity of any side effects or perceived safety concerns, especially for new therapeutic treatments such as gene therapy; and
•whether competing products or other alternatives are more convenient or easier to administer, including alternatives that offer a less frequent dosing regimen than monthly intravitreal injections, in the case of Zimura, or
88
a less invasive method of administration than subretinal injection, in the case of our gene therapy product candidates, come to market. For example, Apellis is testing its complement inhibitor product candidate for GA with both monthly and every other month dosing regimens, and may obtain a label with an every other month dosing regimen, while we expect that any label we may obtain for Zimura in GA will require monthly administrations. If so, physicians and patients may find Apellis's dosing regimen more acceptable than ours.
Our development program for Zimura in GA uses an anatomical primary endpoint, the mean rate of change in GA growth over 12 months. We believe that this efficacy assessment is most likely to demonstrate clinical relevance for an investigational product across a heterogeneous GA patient population and other potential assessments, such as comparisons of visual acuity, are not as clinically meaningful for patients with GA. However, to date there is no direct functional corollary to the anatomical measure that we are using as our primary endpoint. Although we evaluated visual acuity as a secondary endpoint in the GATHER1 trial, the trial was not designed to reliably assess differences in mean changes in visual acuity with statistical significance. Patients, physicians and payors may not recognize the value of, and we may not be able to obtain marketing or reimbursement approval for, Zimura without demonstrating a functional benefit to vision. To do so, we may need to conduct additional clinical trials or sub-studies, which may not ultimately demonstrate a functional benefit to vision.
For each of our Zimura trials where patients receive multiple intravitreal injections on the same day, including the STAR trial, we have provided for a delay in the second intravitreal injection to occur during the same office visit to minimize the risk of an unacceptable increase in intraocular pressure as a result of the volume of the multiple injections. If Zimura receives marketing approval for a particular indication, including for example, for autosomal recessive Stargardt disease, and the approved label requires a waiting period between injections administered on the same day or a dosing regimen that requires multiple office visits per month, the potential market opportunity for Zimura may be limited to the extent that physicians and patients find such a waiting period or dosing regimen unacceptable.
In addition, the potential market opportunity for any product candidate is difficult to estimate precisely. Our estimates of the potential market opportunity for our product candidates include several key assumptions based on our expectations of the safety and effectiveness of the relevant product candidate, the expected patient population for our product candidates, our industry knowledge, the competitive landscape for the indications for which we are developing our product candidates, market response to anti-VEGF agents currently approved for treatment of wet AMD and to Spark Therapeutics's Luxturna® and Novartis AG's Zolgensma®, third-party research reports and other surveys. The potential market opportunity for our product candidates may also differ across geographies. While we believe that our internal assumptions are reasonable, any of these assumptions could prove to be inaccurate, and the actual market for such product candidates could be smaller than our estimates of our potential market opportunity.
There is a variety of factors that could contribute to the actual number of patients who receive an approved therapy being less than our estimates of the potential addressable market. With respect to our programs for orphan diseases, our understanding of both the number of people who have these diseases, as well as the subset of people with these diseases who have the potential to benefit from treatment with our product candidates, are based on estimates. These estimates may prove to be incorrect and new studies may reduce the estimated incidence or prevalence of these diseases. The number of patients in the United States, the European Union and elsewhere may turn out to be lower than expected, patients may not be amenable to treatment with our products or patients may become increasingly difficult to identify and access, all of which would adversely affect our business, financial condition, results of operations and prospects. Further, the severity of the progression of a disease up to the time of treatment, especially in certain degenerative conditions such as GA and certain IRDs, likely will diminish the therapeutic benefit conferred by a new drug product due to irreversible cell death. For example, certain GA patients may have experienced the loss of certain portions of retinal tissue that disproportionately affected their functional vision, and these patients may not value a treatment that can only slow the growth of additional GA lesions without providing a treatment to their loss of functional vision. Certain patients’ immune systems and prior exposure to the virus used to deliver a gene therapy might inhibit the successful delivery of certain gene therapy products to the target tissue, thereby limiting eligibility for treatment or limiting treatment outcomes. If the number of patients that may benefit from the treatments we are seeking to develop is lower than we expect, our business, financial condition, results of operations and prospects may be adversely affected.
Even if we are able to commercialize any of the product candidates that we may develop, the product may become subject to unfavorable pricing regulations, pricing dynamics, third-party reimbursement practices or healthcare reform initiatives, which would harm our business.
The regulations that govern marketing approvals, pricing and reimbursement for new drug products vary widely from country to country. Health care reform, including increasing scrutiny of drug prices, is an issue of intense political focus, particularly in the United States. Current and future legislation may significantly change the approval requirements in ways that could involve additional costs and cause delays in obtaining approvals or in ways that could alter the mechanism by which
89
pharmaceutical prices are negotiated or otherwise determined. Many countries outside the United States require approval of the sale price of a drug before it can be marketed, and to apply for and obtain such an approval in certain countries, we or a commercialization partner may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidate to other available therapies. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control or negotiation even after initial approval is granted. In particular for Zimura in GA, we may need to demonstrate a relative benefit in functional vision in order to obtain reimbursement approval, although our clinical trials, which use an anatomic endpoint as the primary efficacy endpoint, are not designed to demonstrate a functional benefit with statistical significance. As a result, we might obtain marketing approval for a product in a particular country, but then be subject to price regulations that delay our or any commercialization partner’s commercial launch of the product, possibly for lengthy time periods, which would negatively impact the revenues we are able to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more product candidates, even if our product candidates obtain marketing approval and are widely accepted and prescribed or used by physicians.
In addition, even in countries where pharmaceuticals are not subject to strict pricing regulations through a governmental review and approval process, we may nonetheless face an unfavorable pricing environment as a result of political pressure or market dynamics. Because there are only two FDA-approved gene replacement therapy products, both of which launched in the United States within the past three years, the pricing environment for gene therapies is in the very early stages of its development. Gene therapies are generally intended to be one-time treatments or, at a minimum, to provide a benefit over an extended period lasting several years. If we are successful in obtaining marketing approval for any of our gene therapy product candidates, we will need to convince third-party payors of the value that our gene therapy product offers. Third-party payors may be unwilling to accept substantial upfront costs for a therapy where the benefits may not be realized or are realized over a period of years during which the patient may no longer be enrolled in the payor's plan. Although payors and manufacturers may be incentivized to agree to outcomes-based payment structures for gene therapies, where manufacturers provide rebates or a portion of the contract price is forgiven if an efficacy or durability threshold is not met for an individual patient, market dynamics in the United States currently do not facilitate these types of outcome-based payments, in particular because of rules that require that government payors, such as Medicaid, receive the “best price” for a drug, regardless of outcome. The perceived high cost for pharmaceutical products to treat orphan diseases, where manufacturers seek to recoup development costs and earn a profit for a therapy intended to treat a relatively small patient population, may attract increased political and public scrutiny. In particular, the $2.1 million list price for Zolgensma has generated significant public scrutiny over the prices of new pharmaceuticals coming to the market, including gene therapies, and as a result, Novartis has proposed permitting third-party payors to pay for Zolgensma in annual installments over five years instead of as a lump sum. Moreover, if we obtain marketing approval for a product candidate, such as Zimura, in more than one indication, including, for example in an orphan indication such as STGD1 and a non-orphan indication such as GA secondary to AMD, such a product candidate likely would only be sold at one price in any given country, regardless of the indications for which it is prescribed. This dynamic may result in our charging a price that does not generate profits in each indication for which the product is approved.
Our ability and the ability of any commercialization partner to commercialize a product candidate successfully also will depend in part on the extent to which reimbursement for these products and related treatments will be available from government health authorities, private health insurers and other organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. A major trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and third-party payors, particularly Medicare, have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications and encouraging the substitution of lower cost or generic products. Pricing pressures recently experienced by the pharmaceutical industry may be further exacerbated by legislative and policy changes under consideration by the new Biden Administration, the U.S. Congress and many states. For example, the previous Trump Administration, through the Center for Medicare & Medicaid Service, or CMS, announced in late 2018 an advance notice of proposed rulemaking describing a potential mandatory reference pricing model for Medicare Part B drugs under which the prices paid for these drugs will be adjusted in relation to an international pricing index that includes prevailing prices from other countries with strict price controls. The reference pricing model has found support from some members of the U.S. Congress. In September 2020, the Trump Administration issued an executive order directing the Secretary of the Department of Health and Human Services, or HHS, to propose rulemaking that would limit the prices paid by Medicare for certain drugs and biologics to the "most favored nation" price. If this kind of rule were to be adopted, especially for AMD drugs where a large portion of the patient population is over the age of 65 and is therefore covered by Medicare, there could be significant downward pressure on prices charged, not only for patients covered by Medicare, but also for patients covered by private insurers who may follow the government’s lead on price. We expect the Biden Administration to pursue additional rulemaking aimed at limiting drug prices. Moreover, increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for pharmaceutical products. We cannot be sure that coverage and
90
reimbursement will be available for any product that we commercialize or any commercialization partner commercializes on our behalf, and, even if these are available, the level of reimbursement may not be satisfactory.
Reimbursement may affect the demand for, or the price of, any product candidate for which we obtain marketing approval. Obtaining and maintaining adequate reimbursement for our products may be particularly difficult because of the higher prices often associated with drugs administered under the supervision of a physician. We or any commercialization partner may be required to conduct expensive pharmacoeconomic studies to justify coverage and reimbursement or the level of reimbursement relative to other therapies that may be on the market. If coverage and adequate reimbursement are not available or reimbursement is available only at limited levels, we may not be able to successfully commercialize any product candidate for which we obtain marketing approval.
There may be significant delays in obtaining reimbursement for newly approved drugs, and coverage may be more limited than the purposes for which the drug is approved by the FDA or similar regulatory authorities outside the United States. For example, several insurers have limited the subpopulation for or imposed additional eligibility criteria for paying for Zolgensma, beyond the requirements of the approved FDA label, such as requiring that any eligible patients must receive another treatment first and demonstrate that the other treatment is ineffective before using Zolgensma. Moreover, eligibility for reimbursement does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution costs. Interim reimbursement levels for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs, and may be incorporated into existing payments for other services. Net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States, which many members of the U.S. Congress expressed an interest in pursuing. In September 2020, HHS issued a rule permitting limited importation of drugs from Canada. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. Our and any commercialization partner’s inability to promptly obtain coverage and profitable payment rates from both government-funded and private payors for any approved products that we develop could have a material adverse effect on our operating results, our financial condition, or our ability to raise capital needed to commercialize products.
For a further discussion of health care reform and other political factors affecting drug prices, see the risk factor herein entitled "Current and future legislative efforts may limit the prices for our products, if and when they are licensed for marketing, which could materially impact our ability to generate revenues."
Ethical, legal and social issues related to genetic testing may reduce demand for any gene therapy product candidates we develop and for which we seek marketing approval.
We anticipate that prior to receiving certain gene therapies, including as part of a clinical trial, patients would be required to undergo genetic testing. Genetic testing has raised concerns regarding the appropriate utilization and the confidentiality of information provided by genetic testing. The ownership of and the lawfulness of using genetic data is an area of the law that is unclear and varies across jurisdictions. Genetic tests for assessing a person’s likelihood of developing a chronic disease have focused public attention on the need to protect the privacy of genetic information. For example, concerns have been raised that insurance carriers and employers may use these tests to discriminate on the basis of genetic information, resulting in barriers to the acceptance of genetic tests by consumers. This dynamic could lead to governmental authorities restricting genetic testing or calling for limits on or regulating the use of genetic testing, particularly for diseases for which there is no known cure, as well as the use of genetic data. Any of these scenarios could decrease the pool of patients willing to participate in a clinical trial for a gene therapy and the demand for a gene therapy once it is approved.
Product liability lawsuits against us or any future commercialization partner could divert resources, cause us to incur substantial liabilities and limit commercialization of any products that we may develop or in-license.
We face an inherent risk of product liability exposure related to the testing of any product candidate that we develop in human clinical trials, and we and any future commercialization partner will face an even greater risk if we commercially sell any products that we develop or in-license. If we become subject to or otherwise cannot successfully defend ourselves against claims that our product candidates or our products caused injuries, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:
•decreased demand for any product candidates or products that we may develop or in-license;
•withdrawal of clinical trial participants;
91
•injury to our reputation and significant negative media attention;
•significant costs to defend the related litigation;
•substantial monetary awards to trial participants or patients;
•loss of revenue;
•reduced time and attention of our management to pursue our business strategy; and
•the inability to commercialize any products that we may develop or in-license.
We currently hold $10.0 million in product liability insurance coverage in the aggregate, with a per incident limit of $10.0 million, which may not be adequate to cover all liabilities that we may incur. We will need to increase our insurance coverage when and if we begin commercializing an approved product. Insurance coverage is increasingly expensive. We may not be able to maintain insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise, including coverage for any local jurisdictions where we conduct clinical trials. In addition, if a commercialization or collaboration partner were to become subject to product liability claims or were unable to successfully defend themselves against such claims, any such commercialization or collaboration partners could be more likely to terminate such relationship with us and therefore substantially limit the commercial potential of our products.
Risks Related to Our Dependence on Third Parties
We contract with third parties for the manufacture of and for providing starting materials for our product candidates for preclinical development activities and clinical trials and expect to continue to do so in the future, including to support potential commercialization. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or product candidates of sufficient quality, which could delay, prevent or impair our development or commercialization efforts. The COVID-19 pandemic has affected our contract manufacturers' operations and the manufacture of our product candidates.
We do not currently own or operate manufacturing facilities for the production of clinical or commercial quantities of any of our product candidates and have a limited number of personnel hired to supervise outside contract manufacturers. We currently rely upon and expect to continue to rely upon third-party contract manufacturers to manufacture preclinical and clinical supplies of product candidates we are developing or may develop and commercial supplies of products if and when approved for marketing by applicable regulatory authorities. Furthermore, we and our contract manufacturers currently rely upon, and for the foreseeable future expect to continue to rely upon, sole-source suppliers of certain raw materials, plasmids and other specialized components of production used in the manufacture and fill/finish of our product candidates.
We have historically relied on, and purchased on a purchase order basis from, a single third-party manufacturer, Agilent, to provide Zimura drug substance. We have engaged a new manufacturer to conduct scale up and validation activities for Zimura drug substance, and if this manufacturer is successful, we intend for this manufacturer to be our primary supplier for Zimura drug substance. However, we do not currently have any contractual commitments with the new manufacturer or Agilent for the long-term clinical or commercial supply of Zimura drug substance. We may ultimately need to rely on the new manufacturer, Agilent or both or other manufacturers for long-term supply of Zimura drug substance. We have also historically relied on a single third-party manufacturer, Ajinomoto, for Zimura drug product. We have engaged a second fill/finish service provider for additional supply of Zimura drug product for our expected needs for the GATHER2 and STAR trials. We plan to rely on Ajinomoto for long-term supply of Zimura drug product using the new vial we have selected. However, we may ultimately need to rely on other manufacturers for long-term supply of Zimura drug product. We purchase the PEG starting material on a purchase order basis from a single third-party supplier. We are in discussions with this supplier for a long-term supply agreement for the PEG starting material. For these and any other manufacturers with which we do not have any contractual commitments for supply, the pricing and other terms for supply may vary, even substantially, over time and could adversely affect our financial results and operations.
We have engaged a gene therapy CDMO for preclinical and Phase 1/2 clinical supply of IC-100 and IC-200. For IC-500, we have engaged a CDMO to conduct process development, scale-up and cGMP manufacture of the drug substance for preclinical toxicology studies and early-stage clinical trials and a different CDMO to conduct formulation development activities.

Our current and anticipated future dependence upon others for the manufacture of the product candidates that we are developing or may develop may adversely affect our business plan and future growth. For example, any performance failure or differing priorities on the part of our existing or future manufacturers could delay preclinical or clinical development or marketing approval of our product candidates. Our dependence on third party manufacturers may limit our ability to commercialize on a timely and competitive basis any products that receive marketing approval. We may not have adequate or timely visibility over issues at our third-party manufacturers, and may not become aware of any such issues until the effect on our programs, if any, has already materialized.
Agilent and our CDMO for IC-100 and IC-200 are currently undergoing rapid expansion, including ramping up for production for existing clients, bringing on additional clients, opening new facilities, installing and validating new equipment, and hiring and training new personnel. Agilent informed us that as a result of competing demands from other customers, its ability to support our future manufacturing activities for Zimura is limited. As a result, we have engaged a new contract manufacturer that may become our primary or sole supplier for Zimura drug substance, and the timing, costs, progress, quality and outcome of our planned manufacturing activities for Zimura may be negatively affected. In addition, expansion experienced by other manufacturers and suppliers that we use, including any issues that they may experience while expanding, could negatively impact the timing, costs, progress, quality and outcome of our planned manufacturing activities with those manufacturers and delay or hinder our development plans.
If any of our third-party manufacturers, fill/finish providers or sole-source suppliers fail to fulfill our contracts or purchase orders, or if any of these manufacturers or suppliers should become unavailable to us for any reason, including as a result of capacity constraints, differing priorities, regulatory compliance issues, financial difficulties or insolvency, we believe that there are a limited number of potential replacement manufacturers or sole source suppliers, and we likely would incur added costs and delays in identifying or qualifying such replacements. We may be unable to establish agreements with such replacement manufacturers, fill/finish providers or sole-source suppliers or to do so on acceptable terms.
As a result of the COVID-19 pandemic, our third-party contract manufacturers and many sole-source suppliers have limited their operations by reducing the number of staff on site and instituting restrictions on visitors and audits. These changes have affected how we work with our manufacturers and have resulted in minor delays to the progress of our manufacturing activities. For example, we were unable to perform person-in-plant (PIP) observations on a number of critical manufacturing activities at our CDMO for IC-100 and IC-200, which caused minor delays to our manufacturing timelines for both product candidates. Additionally, shortages and governmental restrictions arising from the COVID-19 pandemic have disrupted and may continue to disrupt the ability of our contract manufacturers to procure items, such raw materials, that are essential for the manufacture of our product candidates. For example, in 2020, the COVID-19 pandemic and governmental measures in response caused a delay to the process development activities at our drug substance manufacturer for IC-500 as a result of difficulty in procuring one of the critical starting materials used in the manufacture of IC-500 from China. The COVID-19 pandemic may cause additional disruptions to the supply of starting materials for our product candidates.
In addition, we and our third party manufacturers source some of the raw and starting materials used in the manufacture of our product candidates from outside the United States. We source the PEG starting material from a supplier outside the United States. Our supplier relationships could be interrupted due to international supply disruptions, including those caused by geopolitical and other issues. For example, trade disputes, trade negotiations or the imposition of tariffs between the United States and its trading partners could cause delays or disruptions in our supply of starting materials for our product candidates.
Reliance on third-party manufacturers entails additional risks, including:
•our product candidates may compete with other product candidates and products for access to a limited number of suitable manufacturing facilities that operate under cGMP conditions;
•reliance on the third party for regulatory compliance, quality assurance and quality control;
•the possible breach of the manufacturing agreement by the third party;
•the possible misappropriation of our proprietary information, including our trade secrets and know-how, or the proprietary information of third parties that we are responsible for protecting; and
•the possible termination or non renewal of the agreement by the third party at a time that is costly or inconvenient for us.
93
Third-party manufacturers may not be able to comply with cGMP regulations or similar regulatory requirements outside the United States. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or products, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our products and harm our business and results of operations.
We rely upon third parties in conducting our preclinical development activities and clinical trials, and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of such activities. The COVID-19 pandemic has affected operations at our academic collaborators and delayed some of our sponsored research activities.
We are relying upon and expect in the future to rely upon third parties, such as contract research organizations, or CROs, clinical data management organizations, biostatisticians, medical institutions (including reading centers) and clinical investigators, in conducting our preclinical testing, analytical testing and clinical trials for our product candidates. These third parties may also have relationships with other entities, some of which may be our competitors. We or these third parties may terminate their engagements with us at any time for a variety of reasons, including a failure to perform by the third parties. If we need to enter into alternative arrangements, our product development activities could potentially be delayed and could potentially be very costly.
We also rely upon our university collaborators to conduct some of our preclinical studies. In particular, Penn has the canine disease models for two of the diseases we are aiming to treat: RHO-adRP and BEST1-related retinal diseases. Our preclinical development plans for IC-200 include conducting certain preclinical studies using the associated canine disease model. In 2020, we experienced some delays in the breeding of the canines for our IND-enabling study for IC-200. If we need to conduct additional preclinical studies using these canines, and these canines are not available to us for any reason, our development of IC-200 could potentially be delayed or otherwise adversely affected.
The COVID-19 pandemic has caused our university collaborators to limit the number of staff on site and the types of activities that may be conducted in their laboratories. Penn restricted their researchers from being on site in their laboratories and closed a number of research centers that our researchers use for data analysis, which has limited their ability to analyze some of the data generated during our preclinical studies. As a result, our receipt of data and reports from some of those studies have been delayed. In addition, we curtailed some of the analysis we had originally planned for one of the preclinical studies for our IC-200 program. The University of Florida, or UF, also limited staff on site in their laboratories and vector production facilities, which has delayed our obtaining certain reagents and other materials used for our gene therapy programs. In addition, UMMS suspended researcher access to their laboratories and the conduct of certain animal studies, which delayed our timelines for our miniCEP290 and miniUSH2A sponsored research programs. In late 2020, another of our academic collaborators suspended enrollment of subjects in one of our non-interventional studies for the IC-100 program for a number of months due to COVID-19 precautions. Shortages and governmental restrictions arising from the COVID-19 pandemic may also disrupt the ability of our academic collaborators, clinical trial sites and other contract research organizations to procure items that are essential for our research and development activities, including, for example, medical and laboratory supplies used in our clinical trials, including personal protective equipment for site staff, or animals that are used for preclinical studies. There is no guarantee that the COVID-19 pandemic will not further impact our supply chain, which could have a material impact on our research and development programs.
Our reliance on these third parties for preclinical testing, analytical testing and clinical development activities reduces our control over these activities but does not relieve us of our responsibilities. For example, we remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA and other regulatory authorities require us to comply with GCPs for conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. We also are required to register ongoing clinical trials and post the results of completed clinical trials on various government-sponsored databases within specified timeframes. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions.
Over the past few years, there has been increasing oversight by the FDA and other regulatory authorities on data integrity, especially in the research and development of novel therapies such as gene therapies. We rely upon the practices of and systems in place at our third party collaborators in generating data to support our preclinical and clinical development programs and for quality control over this data. Their practices and systems vary in scope and effectiveness and we have a limited number of personnel to supervise, including to perform quality assurance of, those practices and systems. The COVID-19 pandemic has prevented us from performing audits on our vendors and clinical trial sites that we otherwise would have performed, which decreases the level of oversight we have over those vendors and clinical trial sites and increases the risk
94
of non-compliance. Any failure of such practices or systems to comply with our stated protocols or regulatory requirements could adversely affect the quality of the data generated by these studies. For a number of our analytical development and testing providers, our CDMOs subcontract and manage that work on our behalf and we have less visibility into or control over their activities. If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our preclinical studies, analytical testing or clinical trials in accordance with regulatory requirements or our stated protocols, we would not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates and would not be able to, or may be delayed in our efforts to, successfully commercialize our product candidates.
We also rely upon other third parties to store, package, label and distribute drug supplies for our clinical trials and to store materials for our development activities. In particular, we rely on a limited number of third parties to store starting materials, drug substance and drug product for our product candidates and programs. Our product candidates are required to be stored and shipped at certain temperatures and a deviation from those requirements may result in delays or additional costs. Any performance failure on the part of these third parties could delay preclinical development, clinical development or marketing approval of our product candidates or commercialization of our products and adversely affect our results of operations.
We rely upon third-party researchers to advance our sponsored research programs. These arrangements may not ultimately yield any promising product candidates for preclinical or clinical development. We may not be able to fully realize the benefits of any intellectual property generated by these arrangements.
Part of our strategy involves collaborative sponsored research to be performed by third-party research institutions. Although we seek to direct this research and advise on the design of these projects as well as critical development decisions, this research is being performed by individuals who are not our employees and the timeline and quality of the research efforts are outside of our direct control. Academic investigators and other researchers may have different priorities than we do as a biopharmaceutical drug development company. The sponsored research agreements we enter into for these programs generally provide that any inventions resulting from the research will be owned by the research institution performing the research, and that we have an option to negotiate for a license to develop and exploit any such inventions. Confidential information and new inventions derived from these research efforts may be disclosed through publications or other means prior to our third-party research collaborators being able to protect such intellectual property through the filing of patent applications. Our third-party research collaborators may not be able to obtain or maintain full ownership of inventions that are derived from the research or associated rights, which may limit their ability to provide us with a license to all relevant intellectual property on terms and conditions that are acceptable to us. Even if our collaborative research efforts yield promising results or new technological advances, they may not ultimately result in our being able to protect, develop or exploit the resulting intellectual property.
If we are not able to establish collaborations to advance our development programs, we may have to alter our development and commercialization plans.
The development and potential commercialization of our product candidates is likely to require substantial additional cash to fund expenses and the hiring of additional qualified personnel. In addition, the development or commercialization of a product candidate in markets outside of the United States requires regulatory expertise and commercial capabilities that are specific to the local market. A number of countries require sponsors to perform a clinical trial in the local jurisdiction or with patients similar to the demographics of the local population as a condition to approving the drug. For some of our product candidates, we may seek to collaborate with pharmaceutical and biotechnology companies for the development and potential commercialization of those product candidates.
We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical trials and other data we have generated for the product candidate, the likelihood of approval by the FDA or similar regulatory authorities outside the United States, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, any patent or other forms of exclusivity for such product candidate and the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge, and industry and market conditions generally. The collaborator may also consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such collaboration could be more attractive than the one with us for our product candidate. For our gene therapy programs, we are party to in-license agreements that limit who we can collaborate with or require the approval of our licensor for us to enter into a collaboration, and any future license agreements that we may enter into may have similar restrictions. Collaborations are complex and time-consuming to negotiate and document. In addition, there have been a significant number of business combinations among pharmaceutical and
95
biotechnology companies over the past decade that have resulted in a reduced number of potential future collaborators and this trend is likely to continue.
If we are unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms, or at all, we may have to curtail the development of a product candidate, reduce or delay its development program or one or more of our other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to fund and undertake development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we fail to enter into collaborations and do not have sufficient funds or expertise to undertake the necessary development and commercialization activities, we may not be able to further develop those product candidates or bring them to market and generate product revenue in line with our expectations.
If we enter into collaborations with third parties for the development or commercialization of our product candidates, any such collaborations will carry numerous risks. If any of our collaborations are not successful, we may not be able to capitalize on the market potential of these product candidates.
We may utilize a variety of types of collaboration, distribution and other marketing arrangements with third parties to develop or commercialize our product candidates, either in the United States, or in markets outside the United States. We also may seek third-party collaborators for development and commercialization of other product candidates we may develop. Our likely collaborators for any sales, marketing, distribution, development, licensing or broader collaboration arrangements include large and mid-size pharmaceutical companies, regional and national pharmaceutical companies and biotechnology companies. If we enter into any arrangements with third parties, we would likely have limited control over the amount and timing of resources that our collaborators dedicate to the development or commercialization of our product candidates. Our ability to generate revenues from these arrangements will depend on our collaborators’ abilities and efforts to successfully perform the functions assigned to them in these arrangements.
Collaborations involving our product candidates could pose numerous risks to us, including the following:
•collaborators, including marketing and distribution collaborators, have significant discretion in determining the efforts and resources that they will apply to these collaborations and may not perform their obligations as expected;
•collaborators may de-emphasize or not pursue development and commercialization of our product candidates or may elect not to continue or renew development or commercialization programs based on clinical trial results, changes in the collaborators’ strategic focus, changes in product candidate priorities or available funding or changes in priorities as a result of a merger, acquisition or other corporate restructuring or transaction;
•collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a product candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing;
•collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our products or product candidates if the collaborators believe that competitive products are more likely to be successfully developed or can be commercialized under terms that are more economically attractive than ours;
•we could grant exclusive rights to our collaborators, which would prevent us from collaborating with others;
•we may be obligated to supply the collaborator with drug substance or drug product in an amount sufficient for its needs, or may be dependent on the supply of certain materials or products by the collaborator;
•disagreements or disputes with collaborators, including disagreements or disputes over proprietary rights, contract interpretation or the preferred course of development or commercialization, might cause delays or termination of the research, development or commercialization of products or product candidates, might lead to additional responsibilities for us with respect to product candidates or might result in litigation or arbitration, any of which would divert management attention and resources, be time-consuming and expensive, and be uncertain in outcome;
96
•collaborators may not properly maintain or defend our intellectual property rights, may infringe the intellectual property rights of third parties, may misappropriate our trade secrets or may use our proprietary information in such a way as to invite litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to litigation and potential liability;
•laws or practices in certain foreign jurisdictions may require that as a condition of working with a collaborator in such jurisdiction, we agree to certain foreign ownership restrictions, use certain local services or providers, share or license certain of our proprietary information or technology or agree to other conditions that are not attractive to us; and
•collaborations may be terminated at the convenience of the collaborator, our breach of the terms of the collaboration or other reasons and, if terminated, we may need to raise additional capital to pursue further development or commercialization of the applicable product candidates.
If a collaborator of ours were to be involved in a business combination or other transaction, the foregoing risks would be heightened, and the business combination or transaction may divert attention or resources or create competing priorities. The collaborator may delay or terminate our product development or commercialization program. If one of our collaborators terminates its agreement with us, we could find it more difficult to attract new collaborators and the perception of our company could be adversely affected.
Collaboration agreements may not lead to development or commercialization of product candidates in the most efficient manner or at all.
We depend on licenses and sublicenses for development and commercialization rights to Zimura, IC-100, IC-200 and our miniCEP290 program. These license arrangements, as well as the Inception 4 Merger Agreement, impose diligence obligations on us. We may enter into similar arrangements with respect to future product candidates or technologies. Termination of licenses or the failure by us or our licensees, including our potential future commercialization or collaboration partners, to comply with obligations under these or other agreements could materially harm our business and prevent us from developing or commercializing our products and product candidates.
We are party to a license agreement with Archemix on which we depend for rights to Zimura. We are party to two different license agreements, each with UFRF and Penn, on which we depend for rights to IC-100 and IC-200. We are also party to a license agreement with UMMS for our miniCEP290 program. These agreements generally impose diligence, development and commercialization timelines, milestone payment, royalty, insurance and other obligations on us. Generally, the diligence obligations contained in these agreements require us to use commercially reasonable efforts to develop, seek regulatory approval for and commercialize the applicable product candidate in the United States and certain territories outside of the United States, including the European Union, Japan and such other markets where it would be commercially reasonable to do so. Under the license agreements for our product candidates, we would not be able to avoid our payment obligations even if we believed a licensed patent right was invalid or unenforceable because the license agreements provide that our licenses to all licensed patent rights would terminate if we challenge the validity or enforceability of any licensed patent right. The Inception 4 Merger Agreement, pursuant to which we acquired IC-500, also imposes specified diligence and milestone payment obligations on us. We may enter into acquisition or licensing agreements in the future that could impose similar obligations on us.
If we fail to comply with our obligations under current or future acquisition and licensing agreements, or otherwise breach an acquisition or licensing agreement as a result of our own actions or inaction or the actions or inactions of our commercialization or collaboration partners, our counterparties may have the right to terminate these agreements, in which event we might not have the rights or the financial resources to develop, manufacture or market any product that is covered by these agreements. Our counterparties also may have the right to convert an exclusive license to non-exclusive in the territory in which we fail to satisfy our diligence obligations, which could materially adversely affect the value of the product candidate being developed under any such agreement. Termination of these agreements or reduction or elimination of our rights under these agreements may result in our having to negotiate new or restated agreements with less favorable terms, seek alternative sources of financing or cause us to lose our rights under these agreements, including our rights to Zimura, IC-100, IC-200, our miniCEP290 program, and other important intellectual property or technology. Any of the foregoing could prevent us from commercializing our product candidates, which could have a material adverse effect on our operating results and overall financial condition. In the case of our limited diligence obligation under the Inception 4 Merger Agreement, a potential breach of our obligation to use commercially reasonable efforts to develop an HtrA1 inhibitor could lead to a lawsuit with the former equityholders of Inception 4 and result in potential liability to us of up to $5.0 million.
97
In addition to the above risks, certain of our intellectual property rights are sublicenses under intellectual property owned by third parties, in some cases through multiple tiers. The actions of our licensors may therefore affect our rights to use our sublicensed intellectual property, even if we are in compliance with all of the obligations under our license agreements. Should our licensors or any of their upstream licensors fail to comply with their obligations under the agreements pursuant to which they obtain the rights that are sublicensed to us, or should such agreements be terminated or amended, our ability to develop and commercialize the relevant product candidates may be materially harmed. While the applicable agreements may contain contractual provisions that would in many instances protect our rights as a sublicensee in these circumstances, these provisions may not be enforceable and may not protect our rights in all instances. Further, we do not have the right to control the prosecution, maintenance and enforcement of all of our licensed and sublicensed intellectual property, and even when we do have such rights, we may require the cooperation of our licensors and their upstream licensors, which may not be forthcoming. Our business could be materially adversely affected if we are unable to prosecute, maintain and enforce our licensed and sublicensed intellectual property effectively.
Moreover, the license agreements for IC-100, IC-200 and our miniCEP290 program reserve for the licensing academic institutions the right to continue to practice for research and educational purposes, the inventions covered by the intellectual property rights that we have in-licensed. These licensing institutions or their collaborators may generate scientific, preclinical or clinical data with respect to our product candidates, separate from our research and development efforts, that is inconsistent with other data for such product candidates, including additional preclinical and clinical data that we develop. Investigators at these institutions may publish, present, or otherwise publicly disclose this data, which may have an adverse impact on the prospects of the development of our product candidates and may harm our business. In addition, these institutions may use these data to support new patent applications which could result in the issuance of patents that may limit our freedom to operate without our obtaining additional licenses to these newly developed inventions.
Risks Related to Our Intellectual Property
If we are unable to obtain and maintain or do not maintain patent protection for our technology and products, or if the scope of the patent protection is not sufficiently broad, our competitors could develop and commercialize technology and products similar or identical to ours, and our ability to successfully commercialize our technology and products may be adversely affected.
We currently rely on and expect to continue to rely on patent rights to protect our competitive position. Once our patents expire, we may not be able to exclude competitors from commercializing products similar or identical to ours. The U.S. patent rights covering Zimura as a composition of matter are expected to expire in 2025. The U.S. patent rights covering methods of treating certain complement protein mediated disorders with Zimura are expected to expire in 2026. The European patent rights covering the composition of matter of Zimura and methods of treating certain complement protein mediated disorders with Zimura are expected to expire in 2025. We expect the clinical development of Zimura to continue for at least the next several years. If so, the patents covering Zimura may expire before the date by which we or a potential commercial partner would be able to commercialize Zimura in the United States or Europe if we seek and obtain marketing approval. Even if we are able to obtain marketing approval for and commercially launch Zimura prior to the expiration of these patents, the remaining term of those patents may be shorter than we anticipate. Although the patent rights under existing patent applications for IC-100, IC-200, IC-500 and our miniCEP290 program are not expected to expire until 2037 or after, we face the same risk with those product candidates and programs and any future product candidates that we may develop.
For our sponsored research agreements with UMMS and Penn, we are generally relying on our university collaborators to generate research and data to support new patent applications. The results of any sponsored research are uncertain and the interests of the universities and university researchers are not necessarily aligned with our interests as a commercial entity. The research may generate limited patentable results or data, or none at all. Furthermore, the universities generally control the filing, prosecution and maintenance of any patents or patent applications resulting from the sponsored research. Therefore, we may not be able to obtain any patent or other exclusivity protections as a result of our collaborative gene therapy sponsored research programs, which could materially diminish or eliminate the value of these programs.
Our licensed patent rights for IC-200 and certain of our licensed patent rights for Zimura and IC-100 are method-of-treatment patents and patent applications. Method-of-treatment patents are more difficult to enforce than composition-of-matter patents because of the risk of off-label sale or use of a drug for the patented method. The FDA does not prohibit physicians from prescribing an approved product for uses that are not described in the product’s labeling. Although use of a product directed by off-label prescriptions may infringe our method-of-treatment patents, the practice is common across medical specialties, particularly in the United States, and such infringement is difficult to detect, prevent or prosecute. Off-label sales of other products having the same drug substance as our product candidates would limit our ability to generate revenue from the sale of such product candidates, if approved for commercial sale. In addition, patent laws in Europe and some other
98
jurisdictions generally make the issuance and enforcement of patents that cover methods of treatment of the human body difficult in those jurisdictions. Further, once the composition-of-matter patents relating to Zimura or IC-100 in a particular jurisdiction, if any, expire, competitors will be able to make, offer and sell products containing the same drug substance as Zimura or IC-100 in that jurisdiction so long as these competitors do not infringe any of our other patents covering Zimura’s or IC-100's composition of matter or method of use or manufacture, do not violate the terms of any marketing exclusivity that may be granted to us by regulatory authorities and they obtain any necessary marketing approvals from applicable regulatory authorities. In such circumstances, we also may not be able to detect, prevent or prosecute off-label use of such competitors’ products containing the same drug substance as Zimura or IC-100, even if such use infringes any of our method-of-treatment patents.
Additionally, we do not currently have any composition-of-matter patent applications or patents covering IC-200. The method-of-treatment patent applications that Penn filed and which we in-licensed may not issue as patents. Even if they are issued as patents, any of the claims covering IC-200 may be declared unpatentable or invalid, or the patents may be declared unenforceable. An inability to secure patent coverage for IC-200 may diminish the value of IC-200 and our competitive position.
Depending on potential delays in the regulatory review process for any of our product candidates, we may be able to obtain patent term extension for one of our patents in the United States under the Hatch-Waxman Act, which permits a patent extension term of up to five years as partial compensation for the portion of the patent term effectively lost during product development and the FDA regulatory review process occurring after the issuance of a patent, but we can provide no assurances that such an extension term will be obtained. Similar to the patent term extension available in the United States, the regulatory framework in the European Union and certain other foreign jurisdictions provides the opportunity to extend the term of a patent that covers an approved drug in certain circumstances. Notwithstanding the availability of patent term extension provisions, we may not be granted patent term extensions because of, for example, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable requirements, such as using diligent efforts to develop a drug candidate. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If we are unable to obtain patent term extension or the term or scope of any such extension is less than we request, any period during which we have the right to exclusively market our product would be shorter than we would otherwise expect, and our competitors may commercialize competing products following our patent expiration, and our revenue could be reduced, possibly materially.
The Hatch-Waxman Act also permits the manufacture, use, offer for sale, sale or importation of a patented invention other than a new animal drug or veterinary biological product, if the manufacture, use, offer for sale, sale or importation is solely for uses that are reasonably related to development of information that could be submitted to the FDA. For this reason, our competitors might be able under certain circumstances to perform activities within the scope of the U.S. patents that we own or in-licensed without infringing such patents. This might enable our competitors to develop during the lifetime of these patents drugs that compete with our product candidates.
Our issued patents may not be sufficient to provide us with a competitive advantage. For example, competitors may be able to circumvent our owned or licensed patents by developing similar or alternative technologies or products in a non-infringing manner. Even if our owned or licensed patent applications issue as patents, they may not issue with a scope broad enough to provide us with any meaningful protection, prevent competitors from competing with us or otherwise provide us with any competitive advantage.
The issuance of a patent is not conclusive as to its inventorship, ownership, scope, term, validity or enforceability, and our owned and licensed patents may be challenged in the courts or patent offices in the United States and abroad. For example, if we receive marketing approval for our product candidates, other pharmaceutical companies may seek approval of generic or biosimilar versions of our products with the FDA or regulatory authorities in other jurisdictions. We may then be required to initiate proceedings against such companies in order to enforce our intellectual property rights. The risk of being involved in such proceedings is likely to increase if our products are commercially successful. In any such proceedings, the inventorship, ownership, scope, term, validity and enforceability of our patents may be challenged. These and other challenges may result in loss of exclusivity or freedom to operate or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to prevent others from using or commercializing similar or identical technology and products or from launching generic or biosimilar versions of our products, or could limit the duration of the patent protection of our technology and products. The launch of a generic version of one of our products in particular would be likely to result in an immediate and substantial reduction in the demand for our product, which could have a material adverse effect on our business. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.
99
The patent prosecution process is expensive and time-consuming, is highly uncertain and involves complex legal and factual questions. Patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents.
Our success depends in large part on our ability to obtain and maintain patent protection in the United States and other countries with respect to our proprietary technology and products. We seek to protect our proprietary position by filing in the United States and in certain foreign jurisdictions patent applications related to our novel technologies and product candidates that are important to our business.
The patent prosecution process is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify or protect patentable aspects of our research and development output before it is too late to obtain patent protection. In addition, we may not pursue or obtain patent protection in all major markets. Moreover, in some circumstances, we do not have the right to control the preparation, filing or prosecution of patent applications, or to maintain the patents, covering technology that we license from third parties or covering technology that a collaboration or commercialization partner may develop, the eventual commercialization of which could potentially entitle us to royalty payments. In some circumstances, our licensors may have the right to enforce the licensed patents without our involvement or consent, or to decide not to enforce or to allow us to enforce the licensed patents. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. If any such licensors fail to maintain such patents, or lose rights to those patents, the rights that we have licensed may be reduced or eliminated and our ability to develop and commercialize any of our products that are the subject of such licensed rights could be adversely affected.
The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and has in recent years been the subject of much litigation. In addition, the laws of foreign jurisdictions may not protect our rights to the same extent as the laws of the United States. For example, patent laws in Europe and some other jurisdictions restrict the patentability of methods of treatment of the human body more than United States law does. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we cannot be certain that we or our licensors were the first to make the inventions claimed in our owned or licensed patents or pending patent applications, or that we or our licensors were the first to file for patent protection of such inventions. Moreover, the U.S. Patent and Trademark Office, or USPTO, might require that the term of a patent issuing from a pending patent application be disclaimed and limited to the term of another patent that is commonly owned or names a common inventor. As a result, the issuance, scope, term, validity, enforceability and commercial value of our patent rights are highly uncertain.
Our pending and future patent applications, and any collaboration or commercialization partner’s pending and future patent applications, may not result in patents being issued which protect our technology or products, in whole or in part, or which effectively prevent others from commercializing competitive technologies and products. In particular, during prosecution of any patent application, the issuance of any patents based on the application may depend upon our or their ability to generate additional preclinical or clinical data that support the patentability of our proposed claims. We or any collaboration or commercialization partner may not be able to generate sufficient additional data on a timely basis, or at all. In addition, the issuance of any patents will depend on the existence of any prior art that comes to the patent examiner's attention during prosecution, sometimes through the actions of third parties, and whether our claimed invention meets the statutory criteria for being granted a patent in light of the prior art. Moreover, changes in either the patent laws or interpretation of the patent laws in the United States or other countries may diminish the value of our or a collaboration or commercialization partner’s patents or narrow the scope of our or their patent protection.
Patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents. The Leahy-Smith America Invents Act, or the Leahy-Smith Act, revised United States patent law in part by changing the standard for patent approval from a “first to invent” standard, which had existed before March 2013, to a “first to file” standard and developing a post-grant review system. For example, if we are the first to invent a new product or its use, but another party is the first to file a patent application on this invention, under the new law the other party may be entitled to the patent rights on the invention.
Moreover, we may be subject to a third-party preissuance submission of prior art to the USPTO, or become involved in opposition, derivation, reexamination, inter partes review, post-grant review, interference proceedings or other patent office proceedings or litigation, in the United States or elsewhere, challenging our patent rights or the patent rights of others. The Leahy-Smith Act expanded the ability of third parties to challenge the patents held by patentees through administrative reviews at the USPTO, which may facilitate others to challenge our patents. Based on available information, we believe that inter partes
100
review proceedings, brought by financial investors who may be selling short the stock of the patent holder, are becoming more prevalent. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights; allow third parties to commercialize our technology or products and compete directly with us, without payment to us; or result in our inability to manufacture or commercialize products without infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to develop or commercialize current or future product candidates.
We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time consuming and unsuccessful.
Competitors may infringe or otherwise violate our patents, trademarks, copyrights or other intellectual property. To counter infringement or other violations, we may be required to file claims, which can be expensive and time consuming. For some of our licensed patent rights, we may need the cooperation of our licensors to file such claims. Any such claims could provoke these parties to assert counterclaims against us, including claims alleging that we infringe their patents or other intellectual property rights. In addition, in a patent infringement proceeding, a court may decide that one or more of the patents we assert is invalid or unenforceable, in whole or in part, construe the patent’s claims narrowly or refuse to prevent the other party from using the technology at issue on the grounds that our patents do not cover the technology. Similarly, if we assert trademark infringement claims, a court may determine that the marks we have asserted are invalid or unenforceable or that the party against whom we have asserted trademark infringement has superior rights to the marks in question. In such a case, we could ultimately be forced to cease use of such marks. In any intellectual property litigation, even if we are successful, any award of monetary damages or other remedy we receive may not be commercially valuable and we may not be able to obtain injunctive relief. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation.
Third parties may initiate legal proceedings or take other actions alleging that we are infringing or otherwise violating their intellectual property rights, the outcome of which would be uncertain and could have a material adverse effect on the success of our business.
Our commercial success depends upon our ability and the ability of our collaborators, including our contract manufacturers and any commercial partners, to develop, manufacture, market and sell our product candidates and products and use our proprietary technologies without infringing or otherwise violating the intellectual property and other proprietary rights of third parties. New patent applications in the field of biotechnology and pharmaceuticals, and gene therapies in particular, are being filed at a rapid pace.
There is considerable intellectual property litigation in the biotechnology and pharmaceutical industries. We or any collaborators may become party to, or threatened with, future adversarial proceedings or litigation regarding intellectual property rights with respect to our products and technology, including interference, derivation, re-examination, post-grant review, inter partes review, opposition, cancellation or similar proceedings before the USPTO or its foreign counterparts. The risks of being involved in such litigation and proceedings may increase as our product candidates near commercialization.
Third parties may assert infringement or other claims against us or our collaborators based on existing or future intellectual property rights. We or they may not be aware of all such intellectual property rights potentially relating to our product candidates and their manufacture, use or sale. In addition, contract manufacturers may inadvertently incorporate intellectual property belonging to third parties into our products or the manufacturing processes for these products without our knowledge. There is a lag between the filing of a patent application, which generally establishes the priority date of a patent claim, and the publication of such patent application. During the period between filing of a patent application and publication of the application, we would not otherwise have a means of discovering the existence or extent of the claimed inventions contained in a filed but unpublished patent application. Patent applications are often drafted broadly, and the scope of patent claims that may ultimately issue may not be known until several years after a patent application is filed and published. We may make development or pipeline decisions based on our belief that our product candidates can be distinguished from patent claims contained in published patent applications or issued patents, that patent claims contained in published patent applications are unlikely to issue as drafted, or that claims contained in issued patents are invalid. These positions regarding third-party intellectual property may not ultimately be successful in litigation. Thus, we do not know with certainty that our product candidates, or our intended manufacture or commercialization thereof, does not and will not infringe or otherwise violate any third party’s intellectual property.
If we are or any of our collaborators is found to infringe or otherwise violate a third party’s intellectual property rights, we or they could be required to obtain a license from such third party to continue developing, manufacturing and marketing our
101
product candidates or products or to continue using a trademark. However, we or our collaborators may not be able to obtain any required license on commercially reasonable terms or at all. Even if we or they were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us or our collaborators and could require us or them to make substantial licensing and royalty payments. We or our collaborators could be forced, including by court order, to cease using or commercializing the infringing technology or product. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees, if we are found to have willfully infringed a patent or other intellectual property right. A finding of infringement could prevent us or our collaborators from making or commercializing our product candidates or force us or them to cease some of our business operations, which could materially harm our business. Claims that we or our collaborators have misappropriated the confidential information or trade secrets of third parties could expose us or them to similar liabilities and have a similar negative impact on our business.
We may be subject to claims by third parties asserting that we or our employees or contractors have misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property.
Many of our employees and contractors were previously employed at universities or other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although we try to ensure that our employees and contractors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these employees or contractors have used or disclosed intellectual property, including trade secrets or other proprietary information, of such employee’s or contractor’s former employer. Litigation may be necessary to defend against these claims.
In addition, while it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact conceives or develops intellectual property that we regard as our own. Moreover, because we acquired some of the rights to our product candidates from third parties, we must rely upon these third parties' practices, and those of their predecessors, with regard to the assignment of intellectual property therein, including the intellectual property rights protecting IC-500 and the other HtrA1 inhibitors we acquired in the Inception 4 acquisition transaction. Our and their assignment agreements may not be self-executing or may be breached, and we may be forced to bring claims against third parties, or defend claims they may bring against us, to determine the ownership of what we regard as our intellectual property.
If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel.
Intellectual property litigation could cause us to spend substantial resources and could distract our personnel from their normal responsibilities.
Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses and could distract our technical and management personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. We may not have sufficient financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace.
Obtaining and maintaining our patent protection depends on compliance with various procedural, documentary, fee payment and other requirements imposed by governmental patent offices, and our patent protection could be reduced or eliminated for non-compliance with these requirements.
Periodic maintenance fees on any issued patent are due to be paid to the USPTO and patent offices in foreign countries in several stages over the lifetime of the patent. The USPTO and patent offices in foreign countries require compliance with a number of procedural, documentary, fee payment and other requirements during the patent application process. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of a patent or patent rights in the relevant jurisdiction. Non-compliance events that could result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official
102
actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. In such an event, our competitors might be able to enter the market sooner than we expect, which would have a material adverse effect on our business.
In addition, we may decide not to pursue patent prosecution in certain markets or jurisdictions. For example, we may decide that the costs of obtaining and maintaining patent protection in a certain jurisdiction may outweigh the commercial benefits of patent protection. If so, our competitors may enter into and commercialize identical or similar products in that jurisdiction and if we choose to commercialize our products in that jurisdiction, we may not be able to exclude our competitors in the same way as if we had chosen to pursue patent prosecution in that jurisdiction.
The COVID-19 pandemic has caused the USPTO and many foreign patent offices to adjust their filing deadlines and requirements for applicants. While some of those changes may be beneficial to us, there is added uncertainty with regard to many procedural requirements, which may result in inadvertent non-compliance with those requirements that result in abandonment or lapse of patent rights. Additionally, the reduced staff and operations at many patent offices may delay the prosecution of patent rights or limit us or our patent agents' ability to interact with them.
If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.
In addition to seeking patents for some of our technology and products, we also rely upon trade secrets, including unpatented know-how, technology and other proprietary information, to maintain our competitive position. We seek to protect these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our outside scientific collaborators, contract manufacturers, potential business development counterparties, advisors and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and consultants. We cannot guarantee that we have executed such agreements with each party that may have or have had access to our trade secrets. Moreover, because we acquired IC-500 and our other HtrA1 inhibitors through the acquisition of Inception 4, we are relying upon Inception 4's, and its prior owner's, practices with regard to the protection of trade secrets and intellectual property rights for the period prior to our acquisition of Inception 4. Any party with whom we or they have executed a non-disclosure and confidentiality agreement may breach that agreement and disclose our proprietary information, including our trade secrets, and we may not become aware of such breach or may not be able to obtain adequate remedies. Our proprietary information may also be obtained by third parties by other means, such as breaches of our physical or computer security systems.
Detecting the disclosure or misappropriation of a trade secret and enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to compete with us and our competitive position would be harmed.
Risks Related to Information Technology and Data Protection
We rely significantly upon our information technology systems and any failure, inadequacy, interruption or security lapse of those systems could harm our ability to operate our business effectively. Information technology risks have become more significant over time, including as a result of widespread remote working during the COVID-19 pandemic.
In the ordinary course of business, we collect, process and maintain personal and other sensitive data on our information technology networks. These data include our intellectual property and other proprietary or confidential information relating to our business as well as proprietary or confidential information of third parties including business collaborators. These data also include personal information relating to our clinical trial participants, employees and contractors, clinical investigators and other study staff and healthcare professionals. The secure maintenance of this sensitive information is critical to our business and reputation.
We have implemented a number of measures to protect our information technology systems. These measures include, among others, creation of a cyber-security governance team and an incident response plan and other standard operating procedures for responding to any cyber-security incidents, mandatory routine cyber-security training, including social engineering training, for our employees and consultants with access to our information technology systems, and engagement of a third-party vendor to regularly assess our informational technology systems and potential vulnerabilities.
103
Despite the implementation of security measures, our information technology systems are vulnerable to compromise, damage, loss or exfiltration from cyber-attacks, computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. In particular, companies and other entities and individuals have been increasingly subject to a wide variety of cyber and ransomware attacks, phishing scams and other attempts to gain unauthorized access to systems and information, including through social engineering. The number and complexity of these threats continue to increase over time. These threats can come from a variety of sources, ranging in sophistication from individual hackers to state-sponsored attacks. Cyber threats may be broadly targeted, or they may be custom-crafted against our information systems. In particular, there have been increasing number of cyber threats and attempts by foreign hackers targeted towards U.S. pharmaceutical and biotechnology companies and vendors they work with.
As a result of the COVID-19 pandemic, we have switched to remote working since March 2020 and as a result, have increasingly relied upon teleconferencing and cloud-based means of communication and data storage. Many other companies have done the same. There have been numerous publicized attempts of bad actors attempting to intercept proprietary communications. We may be similarly susceptible to those kinds of threats.
Cyber-attacks have become more prevalent and much harder to detect and defend against. Our networks and storage applications may be subject to unauthorized access by hackers or breached due to human error, malfeasance or other system disruptions. We may not anticipate or immediately detect such incidents and the damage caused by such incidents. System failures, data breaches and any unauthorized access, use or disclosure of our information or data could compromise our intellectual property and expose sensitive business information; lead to unauthorized exposure of personal information of our clinical trial participants, our employees or contractors, our clinical investigators or other study staff, or others we work with; and/or result in disruptions to our research and development activities and business operations, including potential product development, regulatory approval and commercialization delays.
In addition, cyber-attacks and the measures we implement to prevent, detect, and respond to them could cause us to incur significant remediation costs, including costs to recover or reproduce any compromised data, expose us to contractual damages and/or regulatory and other liability, require us to make certain breach notifications, and divert the attention of our management and key information technology resources. Any loss of preclinical data or clinical trial data could result in delays to our product development, marketing approval and commercialization efforts. We may not have adequate insurance coverage to provide compensation for any losses associated with such events and cybersecurity insurance is becoming more expensive. Any breach of security could harm our reputation and deter patients, clinical investigators, or other healthcare professionals and business collaborators from participating in our clinical trials or otherwise working with us.
We also rely significantly upon the information technology systems of our third-party service providers and any failure, inadequacy, interruption or security lapse of those systems could harm our ability to operate our business effectively. We have limited control and oversight over the information security systems and practices of third parties.
In the ordinary course of business, we rely on third parties, including clinical trial sites, CROs, CDMOs and other service providers, to collect, process and maintain personal and other sensitive data on their respective networks for our research and development activities and other business operations. These data include our intellectual property and other proprietary or confidential information relating to our business, as well as personal information relating to our clinical trial participants, employees and contractors, and clinical investigators and other study staff. The maintenance of our data by third parties does not absolve us of our responsibility for the security and integrity of this data.
We have limited control and oversight over the information security systems and practices of third parties. Those systems and practices vary widely in sophistication and robustness. We have limited personnel and resources to oversee the information security systems of third parties with whom we work.
Like our information security systems, those of our third-party service providers are vulnerable to compromise, damage, loss or exfiltration from cyber-attacks, computer viruses, unauthorized access and other causes. Our third-party service providers may not anticipate or immediately detect such incidents and the damage caused by such incidents or notify us in a timely or complete manner. System failures, data breaches and any unauthorized access, use or disclosure of our information or data maintained by our third-party service providers could lead to similar consequences for us as similar events involving our information technology systems, including compromise of our intellectual property or other sensitive personal or business information, disruptions and delays to our research and development activities and other operations, contractual and regulatory liability, data breach notifications, expenditure of significant costs and resources for remediation and harm to our reputation.
104
In September 2020, one of our vendors for the GATHER2 trial suffered a ransomware attack on several of its servers. While this vendor investigated and worked to mitigate the effects of the incident, we deployed a backup process for the work this vendor was performing for us. Although we do not believe this incident had a material impact on the GATHER2 trial or otherwise on our business or operations, similar kinds of incidents may occur in the future with this or our other vendors.
Compliance with global privacy and data security requirements could result in additional costs and liabilities to us or inhibit our ability to collect and process data in line with our expectations, and the failure to comply with such requirements could have a material adverse effect on our business, financial condition or results of operations.
The regulatory framework for the collection, use, safeguarding, sharing, transfer and other processing of personal information is rapidly evolving worldwide and is likely to remain uncertain for the foreseeable future. Globally, virtually every jurisdiction in which we operate has established its own data security and privacy frameworks with which we must comply, and those frameworks may not be consistent. For example, the collection, use, disclosure, transfer, or other processing of personal data regarding individuals in the European Union, including personal health data, is subject to the General Data Protection Regulation, or GDPR, which became effective on May 25, 2018. The GDPR is wide-ranging in scope and imposes numerous requirements on companies that process personal data, including requirements relating to processing health and other sensitive data, obtaining consent of the individuals to whom the personal data relates, providing information to individuals regarding data processing activities and their rights, conducting data protection impact assessments before starting certain processing activities, implementing safeguards to protect the security and confidentiality of personal data, providing notification of data breaches, and taking certain measures when engaging third-party data processors. The GDPR also imposes strict rules on the transfer of personal data to countries outside the European Union, including the United States, some of which are currently in flux, and permits data protection authorities to impose large penalties for violations of the GDPR, including potential fines of up to €20 million or 4% of annual global revenues, whichever is greater. The GDPR also confers a private right of action on data subjects and consumer associations to lodge complaints with supervisory authorities, seek judicial remedies, and obtain compensation for damages resulting from violations of the GDPR. The GDPR also provides certain discretion to individual European member states, and many of them have enacted local legislation implementing the GDPR that differ from one another. The GDPR compliance framework is evolving as data protection authorities enforce applicable requirements and as European courts interpret the GDPR. We are aware that many other countries have enacted or are considering legislation similar to the GDPR.
Similar actions are either in place or under way in the United States. There are a broad variety of data protection laws that are applicable to our activities, and a wide range of enforcement agencies at both the state and federal levels with the authority to review our privacy and data security practices. The Federal Trade Commission and state Attorneys General have been increasingly active in reviewing companies' privacy and data security practices in relation to consumer information. New legislation and regulations are being considered, and in certain cases enacted, at both the state and federal levels. For example, the California Consumer Privacy Act, or the CCPA, which went into effect on January 1, 2020, and its replacement, the California Privacy Rights Act, which will become effective on January 1, 2023, are creating similar risks and obligations as those created by the GDPR, although the CCPA exempts certain information collected as part of a clinical trial that is subject to the Federal Policy for the Protection of Human Subjects (the Common Rule). The New York SHIELD Act, which became fully effective in March 2020, imposes certain data security and data breach notification requirements on organizations that collect personal information of New York residents. Many other states are considering similar legislation. A broad range of legislative measures are being introduced at the federal level. Accordingly, failure to comply with federal and state laws (both those currently in effect and future legislation) regarding privacy and security of personal information could expose us to fines and penalties under such laws. We also may be subject to consumer class action litigation related to alleged noncompliance with these laws. Even if we are not determined to have violated these laws, responding to government investigations and/or consumer litigation in these areas typically requires the expenditure of significant resources and has the potential to generate negative publicity, which could harm our reputation and our business.
Given the breadth and depth of changes in data protection obligations, preparing for and complying with these requirements has required and will continue to require significant time, resources and a review of our technologies, systems and practices, as well as those of any third-party collaborators, service providers, contractors or consultants that process or transfer personal data on our behalf. The GDPR and other changes in laws or regulations associated with the enhanced protection of certain types of sensitive data, such as healthcare data or other personal information from our clinical trials, have resulted in certain changes to our business practices, such as additional consideration given to the GDPR and other relevant data protection laws in setting up clinical trial agreements and informed consent forms for our GATHER2 trial, and may require further changes to our business practices. Any non-compliance by us or our employees, consultants or contractors with the GDPR or other applicable data protection laws could lead to setbacks in the development or approval of our product candidates, government enforcement actions, private litigation, significant fines and penalties, or reputational harm and could have a material adverse effect on our business, financial condition or results of operations.
105
Risks Related to Employee Matters and Managing Our Operations
We are a development-stage company with a limited number of employees to oversee our research and development programs and general and administrative functions. We may experience difficulties in recruiting necessary personnel and in retaining key employees and consultants.
We are a development-stage company with a total of 57 full-time employees as of January 31, 2021. These employees support key areas of our business and operations, including clinical operations, regulatory affairs, drug safety, data management, medical affairs, scientific research, process and analytical development, drug substance and drug product manufacturing, quality control, materials and supply chain management, and quality assurance, as well as all of our general and administrative functions and public company infrastructure.
We remain highly dependent on David R. Guyer, M.D., our executive chairman, and Glenn P. Sblendorio, our chief executive officer and president, as well as the other principal members of our management, scientific and clinical teams. We do not maintain “key person” insurance for any of our executives or other employees. Although we have entered into letter agreements with our executive officers, each of them and our non-executive employees may terminate their employment with us at any time. As a result, key employees whom we expect to retain to assist with the growth of our business may choose not to remain employees. Additionally, because of our size, we have only a small number of employees supporting some of the key areas of our business and operations. If any of those employees were to leave our company or become unavailable due to the COVID-19 pandemic or other reasons, the loss of their services could seriously disrupt our ability to carry on our operations as planned and seriously harm our ability to successfully implement our business plan.
Furthermore, replacing any of our executive officers and key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain marketing approval of and commercialize products. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms, if at all, given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. As we conduct our GATHER2 trial and the expanded STAR trial, prepare for the future development and potential commercialization of Zimura, and continue the development of IC-500 and our gene therapy programs, we have been and expect we will need to continue hiring additional clinical operations, quality assurance, manufacturing, analytical, medical, regulatory and other personnel from this limited pool. We also experience competition for the hiring of scientific, technical and clinical personnel from universities and research institutions. The COVID-19 pandemic has made interviewing and hiring qualified candidates more difficult.
In addition to our employees, we rely on consultants and advisors, including scientific, technical and clinical advisors, to assist us in formulating our research and development, manufacturing, commercialization and lifecycle management strategies. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us. Many consultants and advisors, especially those with gene therapy experience, are high demand and we may not be able to obtain or retain their services for any number of reasons, which could limit our ability to pursue our strategy.
As a result of the COVID-19 pandemic, our entire company has been working remotely since March 2020 and we expect to continue working remotely for the foreseeable future. Our ability to continue to work remotely and when the conditions are appropriate, transition effectively to working in our offices, may affect our operations and the success of our company going forward.
In March 2020, we instituted a company-wide working from home policy, which has remained in effect. Our working from home policy may negatively impact productivity or disrupt our business, the magnitude of which will depend, in part, on the length of this remote working arrangement and other limitations on our ability to conduct our business in the ordinary course. We expect to work from home for the foreseeable future and will closely follow the guidance from federal and state authorities, including the Centers for Disease Control and Prevention, the New York State Department of Health and the New Jersey Department of Health, in deciding if and when to transition back to working in our offices. We are also exploring new office space that may be more cost effective and suitable for working in a safe and socially distanced manner. We expect the transition to working in our offices, if any, to occur in stages, which will depend on, among other factors, the local COVID-19 situation and the degree to which our employees have received vaccines. If and when we transition back to working at company sites, there may be an increased risk to our employees and contractors, including as a result of a subsequent waves of the COVID-19 pandemic. If any of them contracts COVID-19 as a result of or while conducting services for us, we may be subject to workers compensation or other claims. Because of our small size and the importance of our employees and contractors to the success of our company, their exposure to the COVID-19 pandemic may adversely affect our ability to carry on our operations.
106
If we fail to establish and maintain effective internal control over financial reporting, our ability to accurately report our financial results could be adversely affected.
A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements would not be prevented or detected on a timely basis. If any material weakness in our internal control over financial reporting is discovered or occurs in the future, our financial statements may contain material misstatements and we could be required to restate our financial results. As previously disclosed, in 2015 our management concluded that we experienced a material weakness in internal controls that required us to restate the relevant financial statements and we took steps that year to address the deficiency and prevent similar deficiencies in the future. Although we have remediated this deficiency in internal control over financial reporting, we cannot be certain that the remedial measures that we took in the past or other measures we take in the future, especially in light of the decrease in staffing in our accounting and finance areas following our reduction in force during 2017, will ensure that we maintain adequate controls over our financial reporting going forward and, accordingly, additional material weaknesses could occur or be identified. The COVID-19 pandemic may also affect the effectiveness of our internal controls. Any future material weaknesses or combination of deficiencies could materially and adversely affect our ability to provide timely and accurate financial information and investors’ confidence in our internal controls and our company, which could cause our stock price to decline.
Risks Related to Regulatory Approval and Marketing of our Product Candidates and Other Legal Compliance Matters
Even if we complete the necessary preclinical studies and clinical trials, the marketing approval process is expensive, time-consuming and uncertain and may prevent us from obtaining approvals for the commercialization of some or all of our product candidates. If we are not able to obtain, or if there are delays in obtaining, required regulatory approvals, we will not be able to commercialize our product candidates, and our ability to generate revenue would be materially impaired.
Our product candidates and the activities associated with their development and commercialization, including their design, testing, manufacture, safety, recordkeeping, labeling, storage, advertising, promotion, sale and distribution and import and export, are subject to comprehensive regulation by the FDA, the EMA and comparable regulatory agencies in other countries.
In general, the FDA and similar regulatory authorities outside the United States require two adequate and well-controlled clinical trials demonstrating safety and effectiveness for marketing approval for an ophthalmic pharmaceutical product. Failure to obtain marketing approval for a product candidate will prevent us from commercializing the product candidate. We have not received approval to market any of our product candidates from regulatory authorities in any jurisdiction. We have only limited experience in filing and supporting the applications necessary to gain marketing approvals and expect to rely upon third-party CROs to assist us in this process. Securing marketing approval requires obtaining positive safety and efficacy data from required clinical trials, as well as the submission of extensive preclinical and clinical data and supporting information to regulatory authorities for each indication to establish the product candidate’s safety and efficacy. Securing marketing approval also requires the submission of information about the product's manufacturing processes to, and inspection of manufacturing facilities by, the relevant regulatory authorities. The FDA or other regulatory authorities may determine that a product candidate that we may develop is not effective, is only moderately effective or has undesirable or unintended side effects, toxicities or other characteristics that preclude our obtaining marketing approval or prevent or limit commercial use.
The process of obtaining marketing approvals, both in the United States and abroad, is expensive, may take many years, if approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product candidates involved. Changes in marketing approval policies during the development period, changes in or the enactment of additional statutes or regulations, or changes in regulatory review for each submitted product application, may cause delays in the approval or rejection of an application. Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient for approval and require additional non-clinical, clinical or other studies. In addition, varying interpretations of the data obtained from preclinical and clinical testing could delay, limit or prevent marketing approval of a product candidate. Any marketing approval we ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not commercially viable.
Marketing approval of novel product candidates such as Zimura and our gene therapy product candidates manufactured using novel manufacturing processes can be more expensive and take longer than for other, more well-known or extensively studied pharmaceutical or biopharmaceutical products, due to regulatory agencies’ lack of experience with them. We believe that the FDA has only granted marketing approval for one aptamer product and two gene replacement products to
107
date. This lack of experience may lengthen the regulatory review process, require us to conduct additional non-clinical studies or clinical trials, increase our development costs, lead to changes in regulatory positions and interpretations, delay or prevent approval and commercialization of these product candidates or lead to significant post-approval limitations or restrictions.
Accordingly, if we or our collaborators experience delays in obtaining approval or if we fail to obtain approval of our product candidates, the commercial prospects for such product candidate may be harmed and our ability to generate revenues would be materially impaired.
Failure to obtain marketing approval in foreign jurisdictions would prevent our product candidates from being marketed in such jurisdictions. The approval requirements in foreign jurisdictions may differ significantly from those in the United States.
In order to market and sell our product candidates in the European Union and many other jurisdictions, we or our third-party commercialization partners must obtain separate marketing approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and can involve additional non-clinical or clinical testing. The time required to obtain approval may differ substantially from that required to obtain FDA approval. The regulatory approval process outside the United States generally includes all of the risks associated with obtaining FDA approval. In addition, in many countries outside the United States, it is required that the product be approved for reimbursement before the product can be sold in that country. We or our third-party commercialization partners may not obtain marketing and/or reimbursement approvals from regulatory authorities outside the United States on a timely basis, if at all. Approval by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside the United States does not ensure approval by regulatory authorities in other countries or jurisdictions or by the FDA. We and our third-party commercialization partners may not be able to file for marketing approvals and may not receive necessary approvals to commercialize our products in any market. If our third-party commercial partners fail to obtain marketing approval in certain jurisdictions, it may diminish the value of our product candidate to them and cause them to terminate their relationship with us.
In June 2016, the electorate in the United Kingdom, or UK, voted in favor of leaving the European Union, commonly referred to as “Brexit”. Following protracted negotiations, the UK left the European Union on January 31, 2020 and European Union rules and regulations ceased to apply to the UK starting on January 1, 2021. In December 2020, the UK government and the European Union agreed on a long-term trade agreement to govern economic relations going forward. Since the existing regulatory framework for pharmaceutical products in the UK is derived from European Union directives and regulations, Brexit could materially impact the future regulatory regime for pharmaceutical products in the UK, which remains uncertain. We are continuing to analyze how Brexit and the recently concluded trade agreement will affect the future regulatory regime for pharmaceutical products in the United Kingdom. Any delay in obtaining, or an inability to obtain, any marketing approvals, as a result of Brexit or otherwise, would prevent us from commercializing our product candidates in the United Kingdom and/or the European Union and restrict our ability to generate revenue and achieve and sustain profitability. If any of these outcomes occur, we may be forced to restrict or delay efforts to seek regulatory approval in the United Kingdom and/or European Union for our product candidates, which could significantly and materially harm our business.
A fast track designation or grant of priority review status by the FDA may not actually lead to a faster development or regulatory review or approval process. The FDA may withdraw fast track designation if it believes that the designation is no longer supported by data from our clinical development program or for other reasons.
The FDA may designate a product for fast track review if it is intended, whether alone or in combination with one or more other products, for the treatment of a serious or life-threatening disease or condition, and if the product demonstrates the potential to address unmet medical needs for such a disease or condition. For fast track products, sponsors may have greater interactions with the FDA and the FDA may initiate review of sections of a fast track product’s application before the application is complete. This rolling review may be available if the FDA determines, after preliminary evaluation of clinical data submitted by the sponsor, that a fast track product may be effective. The sponsor must also provide, and the FDA must approve, a schedule for the submission of the remaining information and the sponsor must pay applicable user fees. However, the FDA’s time period goal for reviewing a fast track application does not begin until the last section of the application is submitted. In addition, the fast track designation may be withdrawn by the FDA if the FDA believes that the designation is no longer supported by data emerging in the clinical trial process or for other reasons.
In April 2020, the FDA granted fast track designation to Zimura for the treatment of GA secondary to dry AMD. Even though Zimura has received fast track designation, we must continue to follow the requirements of the program in order to maintain the fast track designation, and even if we maintain the designation, we may not ultimately experience a faster development process, review or approval compared to conventional FDA procedures. The FDA's grant of fast track designation
108
to Zimura for the treatment of GA secondary to dry AMD does not imply that the FDA will grant fast track designation to Zimura for another indication, such as STGD1, or that the FDA will grant fast track designation for any of our other product candidates, if we choose to apply for fast track designation.
A breakthrough therapy designation by the FDA for our product candidates may not lead to a faster development or regulatory review or approval process, and it does not increase the likelihood that our product candidates would receive marketing approval.
In 2012, Congress enacted the Food and Drug Administration Safety and Innovation Act, or FDASIA. This law established a new regulatory scheme allowing for expedited review of products designated as “breakthrough therapies.” A product may be designated as a breakthrough therapy if it is intended, either alone or in combination with one or more other products, to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the product may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. The FDA may take certain actions with respect to breakthrough therapies, including holding meetings with the sponsor throughout the development process; providing timely advice to the product sponsor regarding development and approval; involving more senior staff in the review process; assigning a cross-disciplinary project lead for the review team; and taking other steps to help design the clinical trials in an efficient manner.
Designation as a breakthrough therapy is within the discretion of the FDA. Accordingly, even if we believe one of our product candidates meets the criteria for designation as a breakthrough therapy, the FDA may disagree and instead decide not to make such designation. In any event, the receipt of a breakthrough therapy designation for a product candidate may not result in a faster development process, review or approval compared to drugs considered for approval under conventional FDA procedures and does not ensure ultimate approval by the FDA. In addition, even if one or more of our product candidates qualify as breakthrough therapies, the FDA may later decide that the products no longer meet the conditions for qualification or that the time period for FDA review or approval will not be shortened.
We currently do not have orphan drug designations or orphan drug exclusivity for any product candidate. If our competitors are able to obtain orphan drug exclusivity for products that constitute the same or similar drug and treat the same indications as our product candidates, we may not be able to have our product candidates approved by the applicable regulatory authority for a significant period of time.
Regulatory authorities in some jurisdictions, including the United States and the European Union, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a product candidate as an orphan drug if it is intended to treat a rare disease or condition, which is generally defined as having a patient population of fewer than 200,000 individuals in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the United States. In the European Union, the EMA’s Committee for Orphan Medicinal Products grants orphan drug designation to promote the development of products that are intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition affecting not more than 5 in 10,000 persons in the European Union and that there exists no satisfactory method of diagnosis, prevention or treatment of the condition in question that has been authorized in the European Community or, if such method exists, that the medicinal product will be of significant benefit to those affected by that condition.
If we request orphan drug designation for any of our product candidates in one or more indications, there can be no assurances that the FDA or the European Commission will grant any of our product candidates such designation. Additionally, the designation of any of our product candidates as an orphan product does not guarantee that any regulatory agency will accelerate regulatory review of, or ultimately approve, that product candidate, nor does it limit the ability of any regulatory agency to grant orphan drug designation to product candidates of other companies that treat the same indications as our product candidates prior to our product candidates receiving exclusive marketing approval.
Generally, if a product candidate with an orphan drug designation receives the first marketing approval for the indication for which it has such designation, the product is entitled to a period of marketing exclusivity, which precludes the FDA or the European Commission, as the case may be, during that marketing exclusivity period from approving another marketing application for a product that constitutes the same or similar drug treating the same indication, except in limited circumstances. If another sponsor receives such approval before we do, regardless of our orphan drug designation, we may be precluded from receiving marketing approval for our product candidate during the applicable exclusivity period. The applicable period is seven years in the United States and 10 years in the European Union. The exclusivity period in the United States can be extended by six months if the sponsor submits pediatric data that fairly respond to a written request from the FDA for such
109
data. In the European Union, the exclusivity period can be extended by two years following the completion of an agreed pediatric investigation plan. The exclusivity period in the European Union can be reduced to six years if a product no longer meets the criteria for orphan drug designation or if the product is sufficiently profitable so that market exclusivity is no longer justified. Orphan drug exclusivity may be revoked, or a competing sponsor may be allowed on the market, if any regulatory agency determines that the request for designation was materially defective or if the sponsor having orphan drug exclusivity is unable to assure sufficient quantity of the product to meet the needs of patients with the rare disease or condition.
Even if we obtain orphan drug exclusivity for a product candidate, that exclusivity may not effectively protect the product candidate from competition because a competing sponsor's drug could nevertheless be approved for the same condition if certain requirements are met. In the United States, even after an orphan drug is approved, the FDA may subsequently approve another drug for the same condition if the FDA concludes that the later drug is not the same drug or is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care. In particular, the concept of what constitutes the "same drug" for purposes of orphan drug exclusivity remains in flux in the context of gene therapies, and the FDA has issued draft guidance suggesting that it would not consider two gene therapy products to be different drugs solely based on minor differences in the transgenes or vectors. In the European Union, marketing authorization may be granted to a similar medicinal product for the same orphan indication if:
•the second applicant can establish in its application that its medicinal product, although similar to the orphan medicinal product already authorized, is safer, more effective or otherwise clinically superior;
•the holder of the marketing authorization for the original orphan medicinal product consents to a second orphan medicinal product application; or
•the holder of the marketing authorization for the original orphan medicinal product cannot supply sufficient quantities of the orphan medicinal product.
Any product candidate for which we obtain marketing approval could be subject to post-marketing restrictions or withdrawal from the market and we or our third-party commercialization partners may be subject to penalties if we or our third-party commercialization partners or our or their manufacturers fail to comply with regulatory requirements or if we or our third-party commercialization partners or our or their manufacturers experience unanticipated problems with our products, when and if any of them are approved.
Any product candidate for which we or our commercialization partners obtain marketing approval, along with the manufacturing processes, post-approval clinical data, labeling, advertising and promotional activities for such product, will be subject to the continued requirements of and review by the FDA and other regulatory authorities. These requirements include submissions of safety and other post-marketing information and reports, registration and listing requirements, cGMP requirements relating to manufacturing, quality control and quality assurance, tracking of complaints and corresponding maintenance of records and documents, requirements regarding the distribution of samples to physicians and recordkeeping. Even if marketing approval of a product candidate is granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed or may be subject to significant conditions of approval or contain requirements for costly post-marketing testing and surveillance to monitor the safety or efficacy of the medicine, including the possible requirement to implement a risk evaluation and mitigation strategy.
The FDA and other agencies, including the Department of Justice, or the DOJ, closely regulate and monitor the post-approval marketing and promotion of products to ensure that they are marketed and distributed only for the approved indications and in accordance with the provisions of the approved labeling. The FDA and DOJ impose stringent restrictions on manufacturers' communications regarding off-label use and if we do not market our products for their approved indications, we may be subject to enforcement action for off-label marketing. Violations of the FDCA and other statutes, including the False Claims Act, relating to the promotion and advertising of prescription drugs may lead to investigations and enforcement actions alleging violations of federal and state health care fraud and abuse laws, as well as state consumer protection laws.
In addition, later discovery of previously unknown adverse events or other problems with our products, manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may yield various results, including:
•restrictions on such products, manufacturers or manufacturing processes;
•restrictions on the labeling or marketing of a product;
•restrictions on distribution or use of a product;
110
•requirements to conduct post-marketing studies or clinical trials;
•warning letters or untitled letters;
•refusal to approve pending applications or supplements to approved applications that we submit;
•recall of products;
•damage to relationships with any potential collaborators;
•unfavorable press coverage and damage to our reputation;
•fines, restitution or disgorgement of profits or revenues;
•suspension or withdrawal of marketing approvals;
•refusal to permit the import or export of our products;
•product seizure;
•injunctions or the imposition of civil or criminal penalties; and
•litigation.
Non-compliance with European Union requirements regarding safety monitoring or pharmacovigilance, and with any applicable requirements related to the development of products for the pediatric population, can also result in significant penalties.
Our and our potential commercialization partners’ relationships with customers and third-party payors will be subject to applicable anti-kickback, fraud and abuse and other healthcare laws and regulations, which could expose us and our commercialization partners to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.
Healthcare providers and third-party payors play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval. Our future arrangements with healthcare providers and third-party payors may expose us and our commercialization partners to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we and our commercialization partners market, sell and distribute any products for which we or they obtain marketing approval. Restrictions under applicable federal and state healthcare laws and regulations include the following:
•the federal Anti-Kickback Statute prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual for, or the purchase, order or recommendation or arranging of, any good or service, for which payment may be made under a federal healthcare program such as Medicare and Medicaid;
•the federal False Claims Act imposes criminal and civil penalties, including through civil whistleblower or qui tam actions, against individuals or entities for, among other things, knowingly presenting, or causing to be presented, false or fraudulent claims for payment by a federal healthcare program or making a false statement or record material to payment of a false claim or avoiding, decreasing or concealing an obligation to pay money to the federal government, with potential liability including mandatory treble damages and significant per-claim penalties, currently set at a minimum of $11,665 and a maximum of $23,331 per false claim;
•the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program or making false statements in connection with the delivery of or payment for benefits, items or services involving a healthcare benefit program;
111
•HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act and its implementing regulations, also imposes obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information, and providing notifications of the breach of such information, by covered entities and certain business partners;
•the federal Physician Payments Sunshine Act requires certain manufacturers of drugs, medical devices and biological products covered by federal healthcare benefit programs to report payments and other transfers of value to physicians and teaching hospitals; and
•analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws and transparency statutes, may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by governmental and non-governmental third-party payors, including private insurers.
Some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government and may require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures. State and foreign laws, such as the GDPR, also govern the privacy and security of health information in some circumstances, many of which differ from HIPAA and each other in significant ways, thus complicating compliance efforts.
If our operations are found to be in violation of any of the laws described above or any governmental regulations that apply to us, we may be subject to penalties, including civil and criminal penalties, damages, fines and the curtailment or restructuring of our operations. Any penalties, damages, fines, curtailment or restructuring of our operations could adversely affect our financial results. As Zimura advances in clinical development and toward potential commercialization, we plan to develop and implement a corporate compliance program to ensure that we will market and sell any future products that we successfully develop in compliance with all applicable laws and regulations, but we cannot guarantee that any such program will protect us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws and regulations. If any such actions are instituted against us and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or other sanctions.
Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our or our commercialization partners’ operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us or them, we or they may be subject to significant civil, criminal and administrative penalties, including damages, fines, imprisonment, exclusion of products from government funded healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of our or their operations. If any of the physicians or other healthcare providers or entities with whom we are doing business or expect to do business is found to be not in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs, and as a result, our relationships with those healthcare providers or third parties may be adversely affected and our business and reputation may suffer.
Current and future legislation may increase the difficulty and costs for us and any future collaborators to obtain reimbursement for any of our product candidates that may receive marketing approval and our ability to generate revenue will be materially impaired.
In the United States and foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect our ability to profitably sell any product candidates for which we obtain marketing approval. We expect that current laws, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional downward pressure on the price that we, or any collaborators, may receive for any approved products. If reimbursement of our products is unavailable or limited in scope, our business could be materially harmed.
In March 2010, President Obama signed into law the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act, or collectively the ACA. In addition, other legislative changes have been proposed and adopted since the ACA was enacted. In August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required
112
goals, thereby triggering the legislation’s automatic reduction to several government programs. These changes included aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, which went into effect in April 2013 and will remain in effect through 2030 under the Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act. The American Taxpayer Relief Act of 2012, among other things, reduced Medicare payments to several providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These laws may result in additional reductions in Medicare and other healthcare funding and otherwise affect the prices we may obtain for any of our product candidates for which we may obtain regulatory approval or the frequency with which any such product candidate is prescribed or used.
Since enactment of the ACA, there have been, and continue to be, numerous legal challenges and Congressional actions to repeal and replace provisions of the law. For example, with enactment of the Tax Cuts and Jobs Act of 2017, which was signed by President Trump on December 22, 2017, Congress repealed the “individual mandate.” The repeal of this provision, which requires most Americans to carry a minimal level of health insurance, became effective in 2019. Further, on December 14, 2018, a U.S. District Court judge in the Northern District of Texas ruled that the individual mandate portion of the ACA is an essential and inseverable feature of the ACA, and therefore because the mandate was repealed as part of the Tax Cuts and Jobs Act, the remaining provisions of the ACA are invalid as well. On December 18, 2019, the Court of Appeals for the Fifth Circuit court affirmed the lower court’s ruling that the individual mandate portion of the ACA is unconstitutional and it remanded the case to the district court for reconsideration of the severability question and additional analysis of the provisions of the ACA. Thereafter, the U.S. Supreme Court agreed to hear this case. Oral argument in the case took place on November 10, 2020, and a ruling by the Court is expected sometime this year. Litigation and legislation over the ACA are likely to continue, with unpredictable and uncertain results.
The Trump Administration also took executive actions to undermine or delay implementation of the ACA, including directing federal agencies with authorities and responsibilities under the ACA to waive, defer, grant exemptions from, or delay the implementation of any provision of the ACA that would impose a fiscal or regulatory burden on states, individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices. On January 28, 2021, however, President Biden issued a new Executive Order which directs federal agencies to reconsider rules and other policies that limit Americans’ access to health care, and consider actions that will protect and strengthen that access. Under this Order, federal agencies are directed to re-examine: policies that undermine protections for people with pre-existing conditions, including complications related to COVID-19; demonstrations and waivers under Medicaid and the ACA that may reduce coverage or undermine the programs, including work requirements; policies that undermine the Health Insurance Marketplace or other markets for health insurance; policies that make it more difficult to enroll in Medicaid and the ACA; and policies that reduce affordability of coverage or financial assistance, including for dependents.
Current and future legislative efforts may limit the prices for our products, if and when they are licensed for marketing, which could materially impact our ability to generate revenues.
The containment of healthcare costs also has become a priority of federal, state and foreign governments and the prices of pharmaceutical products have been a focus in this effort. Governments have shown significant interest in implementing cost-containment programs, including rebate programs, price controls, restrictions on reimbursement and requirements for substitution of generic products. Efforts to control drug pricing have garnered bipartisan support in U.S. Congress. To that end, the Trump Administration published final rules that would allow states or certain other non-federal government entities to submit importation program proposals to the FDA for review and approval. Applicants would be required to demonstrate their importation plans pose no additional risk to public health and safety and will result in significant cost savings for consumers. Earlier, the FDA had issued draft guidance that would allow manufacturers to import their own FDA-approved drugs that are authorized for sale in other countries (multi-market approved products). Further, President Trump issued five executive orders intended to lower the costs of prescription drug products. Several of these orders are reflected in recently promulgated regulations, and one of these regulations is currently subject to a nationwide preliminary injunction.
The Biden Administration has frozen certain of the previous administration’s measures to reform drug prices, pending further review It remains to be seen how the Biden Administration will address this issue. The Biden Administration may pursue reference pricing policies, which is a regime that sets the price of certain drugs by reference to the average price of these drugs in other developed countries, or may seek to amend existing law that currently bans Medicare from negotiating lower prices with drug manufacturers.
At the state level, legislatures are increasingly passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In addition, regional health care authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their
113
prescription drug and other health care programs. These measures could reduce the ultimate demand for our products, once approved, or put pressure on our product pricing. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our product candidates or additional pricing pressures.
Finally, outside the United States, in some nations, including those of the EU, the pricing of prescription pharmaceuticals is subject to governmental control and access. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we or our collaborators may be required to conduct a clinical trial that compares the cost-effectiveness of our product to other available therapies. If pricing for our products, if approved and licensed, is set at unsatisfactory levels, our business could be materially harmed.
Our operations may be dependent on the normal function of the FDA, the SEC and other government agencies. The inability of those agencies to obtain necessary funding and other effects from the political process could prevent those agencies from performing normal functions on which the operation of our business may rely, which could negatively impact our business.
The ability of the FDA to review and approve new product applications such as INDs, new drug applications and biologics license applications can be affected by a variety of factors, including government funding levels, ability to hire and retain key personnel and to accept the payment of user fees, and statutory, regulatory, and policy changes. Government funding of the FDA, the SEC and other government agencies on which our operations rely is subject to the political process, which is fluid and unpredictable. For example, over the past decade, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical employees and stop critical activities. Additionally, the COVID-19 pandemic has caused many regulatory agencies, including the FDA, to reduce staff availability and operations. We may face impediments to scheduling or conducting regulatory meetings, inspections and approvals due to measures intended to limit in-person interactions. If a prolonged government restriction or shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, in our operations as a public company, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.
We are subject to U.S. and foreign anti-corruption and anti-money laundering laws with respect to our operations and non-compliance with such laws can subject us to criminal and/or civil liability and harm our business.
We are subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended, or the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. International Travel Act of 1961, the USA PATRIOT Act, and possibly other state and national anti-bribery and anti-money laundering laws in countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees, agents, third-party intermediaries, joint venture partners and collaborators from authorizing, promising, offering, or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector. We have relationships with certain officials and employees of government agencies or government-affiliated hospitals, universities, and other organizations, including a number of public hospitals that are our clinical trial sites. In addition, we may engage third party intermediaries to promote our clinical research activities abroad and/or to obtain necessary permits, licenses, and other regulatory approvals. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, partners, and agents, even if we do not explicitly authorize or have actual knowledge of such activities.
Noncompliance with anti-corruption and anti-money laundering laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension and/or debarment from contracting with certain persons or governmental programs, the loss of export privileges, reputational harm, adverse media coverage, and other collateral consequences. If any subpoenas, investigations, or other enforcement actions are launched, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations and financial condition could be materially harmed. In addition, responding to any action will likely result in a materially significant diversion of management’s attention and resources and significant defense and compliance costs and other professional fees. In certain cases, enforcement authorities may even cause us to appoint an independent compliance monitor which can result in added costs and administrative burdens.
114
If we or our third-party manufacturers fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could harm our business.
We and our third-party manufacturers are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. From time to time and in the future, our operations may involve the use of hazardous and flammable materials, including chemicals and biological materials, and produce hazardous waste products. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from our or our contractors' use of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources and any coverage provided by our insurance. We also could incur significant costs associated with civil or criminal fines and penalties for failure to comply with such laws and regulations.
Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us.
In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations may impair our research, development or production efforts. Our failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions. We expect the new Biden Administration to pass additional such laws and regulations.
Further, with respect to the operations of our third-party contract manufacturers, it is possible that if they fail to operate in compliance with applicable environmental, health and safety laws and regulations or properly dispose of wastes associated with our product candidates or products, we could be held liable for any resulting damages, suffer reputational harm or experience a disruption in the manufacture and supply of our product candidates or products.
Risks Related to Our Common Stock
Provisions in our corporate charter documents and under Delaware law could make an acquisition of us, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove members of our board of directors and management.
Provisions in our certificate of incorporation and our by-laws may discourage, delay or prevent a merger, acquisition or other change in control of our company that stockholders may consider favorable, including transactions in which our stockholders might otherwise receive a premium for their shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In addition, because our board of directors is responsible for appointing the members of our management team, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. Among other things, these provisions:
•provide for a classified board of directors such that only one of three classes of directors is elected each year;
•allow the authorized number of our directors to be changed only by resolution of our board of directors;
•limit the manner in which stockholders can remove directors from our board of directors;
•provide for advance notice requirements for stockholder proposals that can be acted on at stockholder meetings and nominations to our board of directors;
•require that stockholder actions must be effected at a duly called stockholder meeting and prohibit actions by our stockholders by written consent;
•limit who may call stockholder meetings;
•authorize our board of directors to issue preferred stock without stockholder approval, which could be used to institute a “poison pill” that would work to dilute the stock ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by our board of directors; and
115
•require the approval of the holders of at least 75% of the votes that all our stockholders would be entitled to cast to amend or repeal certain provisions of our certificate of incorporation or by-laws.
Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.
The price of our common stock may be volatile and fluctuate substantially, which could result in substantial losses for stockholders.
Our stock price may be volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control. The stock market in general, and the market for smaller pharmaceutical and biotechnology companies in particular, have experienced extreme volatility that has often been unrelated to the operating performance of particular companies, including as a result of short selling by institutional and retail investors. As a result of this volatility, our stockholders may not be able to sell their shares of common stock at or above the price at which they purchased their shares. The market price for our common stock may be influenced by many factors, including:
•results of research, preclinical development activities and clinical trials for our product candidates and the timing of the receipt of such results;
•the success of products or technologies that compete with our product candidates, including results of clinical trials of product candidates of our competitors;
•actual or anticipated changes in estimates as to financial results, development timelines or recommendations by securities analysts;
•the level of expenses related to any of our product candidates or development programs;
•variations in our financial results or those of companies that are perceived to be similar to us;
•the recruitment or departure of key personnel;
•the results of our efforts to in-license or acquire the rights to other product candidates and technologies for the treatment of retinal diseases;
•developments or disputes concerning patent applications, issued patents or other proprietary rights;
•relevant scientific and medical developments;
•changes in the structure of healthcare payment systems;
•market conditions in the pharmaceutical and biotechnology sectors;
•general economic, industry and market conditions, such as those caused by the COVID-19 pandemic;
•political, social, regulatory or legal developments in the United States and other countries; and
•the other factors described in this “Risk Factors” section.
In addition, the COVID-19 pandemic has caused significant disruptions in the financial markets, and may continue to cause such disruptions, and has also impacted, and may continue to impact, the volatility of our stock price and trading in our stock. Following periods of volatility in the market price of a company’s stock, securities class-action litigation has often been instituted against that company. For example, we and certain of our current and former executive officers have been named as defendants in a purported class action lawsuit and a related shareholder derivative action following our announcement in December 2016 of the initial, top-line results from the first two of our Phase 3 Fovista trials for the treatment of wet AMD. See “Risks Related to Our Business Plan, Financial Position and Need for Additional Capital—We and certain of our current and former executive officers have been named as defendants in lawsuits that could result in substantial costs and divert management’s attention.” These proceedings and other similar litigation, if instituted against us, could cause us to incur
116
substantial costs to defend such claims and divert management’s attention and resources, which could seriously harm our business, and cause additional volatility in the price of our common stock.
If a significant portion of our total outstanding shares are sold into the market, the market price of our common stock could drop significantly, even if our business is doing well.
Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock. For example, we issued 8,649,453 shares of our common stock to funds affiliated with Vivo Capital, LLC and Samsara BioCapital, LP in a private placement in June 2020. In accordance with our obligations under a stock purchase agreement executed in connection with the private placement, we have filed a registration statement on Form S-3 with the Securities and Exchange Commission for the purposes of registering for resale these shares, which has been declared effective by the SEC, pursuant to which such shares can be freely sold and traded. If the holders of these shares sell, or the market perceives that these holders will sell, the shares currently held by them, the price of our common stock may decline.
Moreover, we have filed, and expect to continue to file, registration statements on Form S-8 registering all shares of common stock that we may issue under our equity compensation plans. Once registered on Form S-8, shares underlying these equity awards can be freely sold in the public market upon issuance, subject to volume, notice and manner of sale limitations applicable to affiliates.
The ownership percentage of our stockholders may be diluted in the future, which could dilute the voting power or reduce the value of our outstanding shares of common stock.
As with any publicly traded company, the ownership percentage of our stockholders may be diluted in the future because of equity issuances for acquisitions, capital markets transactions, business development transactions or otherwise, including equity awards that we intend to continue to grant to our directors, officers and employees pursuant to our equity compensation plans. Our employees are also entitled, subject to certain conditions, to purchase our common stock at a discount pursuant to our Employee Stock Purchase Plan.
In addition, the pre-funded warrants that we issued in connection with our December 2019 and June 2020 public offerings are exercisable at any time, and any exercise of such warrants will increase the number of shares of our outstanding common stock, which may dilute the ownership percentage or voting power of our stockholders. To date, pre-funded warrants representing approximately 2.5 million shares of common stock have been exercised and as of December 31, 2020, pre-funded warrants representing 3,164,280 shares of common stock remain outstanding.
Also, our certificate of incorporation authorizes us to issue, without the approval of our shareholders, one or more classes or series of preferred stock having such designation, powers, preferences and relative, participating, optional and other special rights, including preferences over our common stock with respect to dividends and distributions, as our board of directors generally may determine. The terms of one or more classes or series of preferred stock could dilute the voting power or reduce the value of our common stock. Similarly, the repurchase or redemption rights or liquidation preferences we could assign to holders of preferred stock could affect the residual value of our common stock.
For more information about the dilutive effects of financing or business development transactions we may undertake, see the risk factor above, "Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates."
We incur significant costs as a result of operating as a public company, and our management is required to devote substantial time to compliance initiatives and corporate governance practices.
As a public company, we incur and will continue to incur significant legal, accounting and other expenses. The Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of The Nasdaq Global Select Market and other applicable securities rules and regulations impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices. Our management and other personnel devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations have increased our legal and financial compliance costs and have made some activities more time-consuming and costly.
Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, we are required to furnish with our periodic Exchange Act reports a report by our management on our internal control over financial reporting. To achieve compliance with Section 404, we must document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources and engage outside consultants to assess
117
and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal control over financial reporting. There is a risk that our internal control over financial reporting may, in the future, be found to be ineffective under Section 404. Our identification of one or more material weaknesses could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements.
Because we do not anticipate paying any cash dividends on our common stock in the foreseeable future, capital appreciation, if any, will be our stockholders’ sole source of gain.
We have never declared or paid cash dividends on our common stock. We currently intend to retain all of our future earnings, if any, to finance the growth of our business. In addition, the terms of any future debt agreements that we enter into may preclude us from paying dividends. As a result, capital appreciation, if any, of our common stock will be our stockholders’ sole source of gain for the foreseeable future.
Item 1B. Unresolved Staff Comments
None.
Item 2. Properties
We lease properties in New York, New York, Cranbury, New Jersey and Parsippany, New Jersey, all of which are used for office space and/or storage of IT equipment.
Item 3. Legal Proceedings
Descriptions of legal proceedings are set forth in "Note 13-Commitments and Contingencies" in the notes to the financial statements filed with this Annual Report on Form 10-K.
We deny any and all allegations of wrongdoing and intend to vigorously defend against these lawsuits. We are unable, however, to predict the outcome of these matters at this time. Moreover, any conclusion of these matters in a manner adverse to us and for which we incur substantial costs or damages not covered by our directors’ and officers’ liability insurance would have a material adverse effect on our financial condition and business. In addition, the litigation could adversely impact our reputation and divert management’s attention and resources from other priorities, including the execution of our business plan and strategies that are important to our ability to grow our business, any of which could have a material adverse effect on our business.
Item 4. Mine Safety Disclosures
None.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis of our financial condition and results of operations should be read together with our financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties and should be read together with the "Risk Factors" section of this Annual Report on Form 10-K for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.
Overview
We are a science-driven biopharmaceutical company focused on the discovery and development of novel treatment options for retinal diseases with significant unmet medical needs. We are currently developing both therapeutic product candidates for age-related retinal diseases and gene therapy product candidates for orphan inherited retinal diseases, or IRDs. We believe that both therapeutics and gene therapy serve important roles in drug development and providing potential treatment options for patients suffering from retinal diseases.
Our therapeutics portfolio consists of our clinical stage product candidate Zimura® (avacincaptad pegol), a complement C5 inhibitor, and our preclinical product candidate IC-500, a High temperature requirement A serine peptidase 1 protein, or HtrA1, inhibitor. We are currently targeting the following diseases with Zimura:
•geographic atrophy, or GA, which is the advanced stage of age-related macular degeneration, or AMD, and is characterized by marked thinning or atrophy of retinal tissue, leading to irreversible loss of vision; and
•autosomal recessive Stargardt disease, or STGD1, which is an orphan inherited condition characterized by progressive damage to the central portion of the retina, or the macula, and other retinal tissue, leading to loss of vision.
We previously also evaluated Zimura in combination with Lucentis® (ranibizumab), an anti-vascular endothelial growth factor, or anti-VEGF, agent, for the treatment of wet AMD, for which we completed a Phase 2a clinical trial, referred to as the OPH2007 trial, during the fourth quarter of 2018. We are developing IC-500 for GA secondary to AMD and potentially other age-related retinal diseases.
Our gene therapy portfolio consists of two product candidates in preclinical development (IC-100 and IC-200) and several ongoing collaborative sponsored research programs, each of which uses adeno-associated virus, or AAV, for gene delivery. These AAV mediated gene therapy programs are targeting the following orphan IRDs:
•rhodopsin-mediated autosomal dominant retinitis pigmentosa, or RHO-adRP, which is characterized by progressive and severe bilateral loss of vision leading to blindness;
•IRDs associated with mutations in the BEST1 gene, including Best vitelliform macular dystrophy, or Best disease, which is generally characterized by bilateral egg yolk-like lesions in the macula, which, over time, progress to atrophy and loss of vision;
•Leber Congenital Amaurosis type 10, or LCA10, which is characterized by severe bilateral loss of vision at or soon after birth;
•autosomal recessive Stargardt disease; and
•IRDs associated with mutations in the USH2A gene, which include Usher syndrome type 2A, or Usher 2A, and USH2A-associated non-syndromic autosomal recessive retinitis pigmentosa.
We are developing IC-100 for RHO-adRP and IC-200 for BEST1-related IRDs.

Research and Development Pipeline
We have summarized the current status of our ongoing research and development programs in the table below.
*We have an option to exclusively in-license intellectual property resulting from ongoing sponsored research.
Therapeutic Development Programs
Zimura
Zimura, our complement C5 inhibitor, is a chemically-synthesized, pegylated RNA aptamer. Aptamers are short molecules made up of a single stranded nucleic acid sequence or amino acid sequence that binds molecular targets with high selectivity and specificity. In April 2020, we received fast track designation from the U.S. Food and Drug Administration, or FDA, for Zimura for the treatment of GA secondary to dry AMD. The following are brief descriptions of the status of the GATHER1 trial, which we completed in June 2020, and our ongoing clinical trials for Zimura and our manufacturing activities for Zimura.
GATHER1 (GA secondary to AMD - Completed)
GATHER1 is an international, randomized, double-masked, sham controlled, multi-center Phase 2/3 clinical trial evaluating the safety and efficacy of Zimura for the treatment of GA secondary to AMD. We enrolled 286 patients in this trial across multiple treatment groups, including various Zimura doses and sham control groups, and patients were treated and followed for 18 months. In October 2019, we announced positive 12-month data from this trial and in June 2020, we completed this trial and announced 18-month data from this trial, which supported the 12-month data. We believe that the GATHER1 trial qualifies as the first of two Phase 3 trials typically required by the FDA for marketing approval of a pharmaceutical product.
GATHER2 (GA secondary to AMD - Ongoing)
GATHER2 is an international, randomized, double-masked, sham controlled, multi-center Phase 3 clinical trial evaluating the safety and efficacy of Zimura for the treatment of GA secondary to AMD. In this trial, we plan to enroll approximately 400 patients, who will be randomized to receive either monthly administration of Zimura 2 mg or sham during the first 12 months of the trial, at which time the primary efficacy analysis of the mean rate of change of GA growth over 12 months, as measured by fundus autofluorescence based on readings at three time points: baseline, month 6 and month 12, calculated using the square root transformation of the GA area, which is the same primary efficacy endpoint we used for the GATHER1 trial, will be performed. At month 12, we plan to re-randomize patients in the Zimura 2 mg arm to receive either monthly or every other month administration of Zimura 2 mg. The final evaluation will take place at month 24.
In June 2020, we dosed the first patient in this trial. We are continuing to recruit and enroll patients and expect to complete patient enrollment during the third quarter of 2021. Meanwhile, we continue to monitor the COVID-19 pandemic closely and may need to slow down or stop patient enrollment in certain geographies depending on the local situation. We have
123
added sites to this trial due to the ongoing and variable nature of the COVID-19 pandemic and its potential impact on patient recruitment and retention.
STAR (STGD1 - Ongoing)
STAR, also known as OPH2005, is an international, randomized, double-masked, sham controlled, multi-center clinical trial evaluating the safety and efficacy of Zimura for the treatment of STGD1. STAR, similar to GATHER1, was designed to be a Phase 2b screening trial, with the potential to demonstrate statistically significant results depending on the magnitude of the potential benefit observed. If the results are positive and statistically significant, we believe this trial could potentially serve as a clinical trial that can support an application for marketing approval. We initially enrolled 95 patients in the STAR trial. All of these initially enrolled patients had completed their scheduled visits as of September 2020.
In July 2020, we reopened enrollment in this trial in the United States. We plan to enroll approximately 25 additional patients, with the goal of enrolling a total of approximately 120 patients. Similar to GATHER2, we continue to monitor the COVID-19 pandemic closely and may need to slow down or stop patient enrollment in certain geographies depending on the local situation. Newly enrolled patients will be randomized on a 1:1 basis to be treated with either Zimura 4 mg or sham for 18 months. We have been and plan to remain masked to the treatment condition of all patients in the trial. In addition, we have not reviewed and do not plan to review or analyze efficacy data for any patients in the trial, until the 18-month data has been collected and analyzed for all patients enrolled in the trial.
Zimura Manufacturing
In early 2017, we completed the small scale manufacture of multiple batches of Zimura drug substance that we are using to support clinical drug supply for the GATHER2 trial and the expanded STAR trial. We have initiated activities in preparation for the scale-up and validation of the manufacturing process for Zimura drug substance with a new manufacturer, with the goal of assessing whether this manufacturer can produce Zimura drug substance at an adequate scale for future potential commercial use. If this manufacturer is successful, we intend for this manufacturer to be our primary supplier of Zimura drug substance. We also recently engaged our historical contract manufacturer for Zimura drug substance, Agilent Technologies, Inc., or Agilent, for scale-up and validation activities. Depending on the success of the scale-up activities by the new manufacturer, we may use either this new manufacturer, Agilent or both for future supply of Zimura drug substance. In addition, regardless of which manufacturer we use, we will need to demonstrate that the drug substance produced through the scaled-up process is analytically comparable to the drug substance we are currently using. We are continuing analytical method development and qualification with our contract manufacturers and laboratories.
In 2020, we engaged a contract manufacturer to provide us with additional supply of finished Zimura drug product to support our needs for the GATHER2 trial and the expanded STAR trial. We expect that this contract manufacturer will be able to supply sufficient finished Zimura drug product for these two clinical trials. In addition, we are planning to make a change to the existing vial used for Zimura drug product, which we believe may allow us to support a more efficient fill/finish operation at a commercial scale. We have been in discussions with our historical fill/finish manufacturer, Ajinomoto Bio-Pharma Services, or Ajinomoto, regarding its capacity to supply us with finished Zimura drug product with the new vial for potential commercial use.
We order the PEG starting material used to make Zimura drug substance from a sole source third-party manufacturer outside the United States. We currently procure the supply on a purchase order basis and are planning to enter into a long-term supply agreement with this manufacturer for the PEG starting material. We are assessing this supplier's capacity to supply the PEG at the scale that we expect we will need for commercial manufacturing.
IC-500: HtrA1 Inhibitor
We are pursuing the preclinical development of IC-500 for the treatment of GA secondary to AMD and potentially other age-related retinal diseases. We have selected IC-500, the lead compound from our HtrA1 inhibitor program, which includes a number of small molecule compounds that show high affinity and specificity for HtrA1 when tested in vitro.
In early 2021, we completed a review of our IC-500 development program, which we had previously designed to support monthly dosing in our planned first-in-human clinical trial. We believe that we may be able to establish, at an earlier stage of development, a dosing regimen for IC-500 with less frequent dosing than we had previously planned. As a result, we have revised our development plans and timelines for IC-500 with the goal of including both monthly dosing and a less frequent dosing regimen in our first-in-human clinical trial. Currently, we are planning to initiate a number of preclinical pharmacokinetic, tolerability and target engagement studies for IC-500. We are also conducting additional formulation
124
development activities and planning for cGMP manufacturing activities for IC-500. Based on current timelines and subject to successful preclinical development and cGMP manufacturing, we expect to file an IND for IC-500 during the second half of 2022.
Gene Therapy Research and Development Programs
IC-100: Product Candidate for RHO-adRP
We are pursuing the preclinical development of IC-100, our novel AAV gene therapy product candidate for the treatment of RHO-adRP. We and the University of Pennsylvania, or Penn, have conducted a number of preclinical studies of IC-100 and a natural history study of RHO-adRP patients. We are working with a gene therapy contract development and manufacturing organization, or CDMO, for preclinical and Phase 1/2 clinical supply of IC-100. We are completing manufacturing activities for a cGMP batch of IC-100 produced by our CDMO and completed toxicology studies of IC-100. We are planning for a Phase 1/2 clinical trial for IC-100, including site selection and other startup activities. We are planning to meet with the FDA to discuss our selected doses for a first-in-human clinical trial before we file an IND for IC-100. Based on current timelines and subject to feedback from the FDA, we plan to file an IND for IC-100 and subject to regulatory review, we expect to begin patient enrollment in a Phase 1/2 clinical trial in the second half of 2021.
IC-200: Product Candidate for BEST1-Related IRDs
We are pursuing the preclinical development of IC-200, our novel AAV gene therapy product candidate for the treatment of BEST1-related IRDs. We and Penn are conducting preclinical studies of IC-200 and natural history studies of patients with BEST1-related IRDs. We are working with a gene therapy CDMO for preclinical and Phase 1/2 clinical supply of IC-200. We are completing manufacturing activities for a cGMP batch of IC-200 produced by our CDMO. We are conducting other IND-enabling activities, including a toxicology study of IC-200. We are planning for a Phase 1/2 clinical trial for IC-200, including site selection and other startup activities. Based on current timelines and subject to successful completion of preclinical development, we plan to file an IND and subject to regulatory review, begin patient enrollment in a Phase 1/2 clinical trial for IC-200 in the second half of 2021.
Minigene Programs
AAV vectors are generally limited as a delivery vehicle by the size of their genetic cargo, which is restricted to approximately 4,700 base pairs of genetic code. The use of minigenes seeks to deliver a smaller but still functional form of a larger gene packaged into a standard-size AAV delivery vector. The goal of minigene therapy is to deliver a gene expressing a protein that, although smaller than the naturally occurring protein, is nonetheless functional for purposes of treating the associated disease.
We are funding several sponsored research programs at the University of Massachusetts Medical School, or UMMS, seeking to use a minigene approach to develop new gene therapies for several orphan IRDs. The following is a summary of these minigene programs and their status:
•miniCEP290 (LCA10): This program, which we refer to as the miniCEP290 program, is targeting LCA10, which is associated with mutations in the CEP290 gene. In July 2019, we entered into a license agreement with the University of Massachusetts, or UMass, for exclusive development and commercialization rights to this program. The sponsored research has yielded a number of minigene constructs that show encouraging results when tested in a mouse model. UMMS is conducting additional experiments to optimize constructs, which were delayed because of restrictions placed by UMMS on animal research activities as a result of the COVID-19 pandemic. We currently expect to identify a lead construct during the second quarter of 2021.
•miniABCA4 (STGD1): This program, which we refer to as the miniABCA4 program, is targeting STGD1, which is associated with mutations in the ABCA4 gene. UMMS generated and evaluated several ABCA4 minigene constructs in both in vitro and in vivo experiments, which yielded what we believe to be encouraging results. UMMS is conducting additional experiments to optimize the constructs. We expect to receive additional results from the miniABCA4 program during the first half of 2021.
•miniUSH2A (USH2A-related IRDs): This program, which we refer to as the miniUSH2A program, is targeting IRDs associated with mutations in the USH2A gene, including Usher 2A and USH2A-associated non-syndromic autosomal recessive retinitis pigmentosa. Some of the activities in this program were delayed as a result of the closure of UMMS
125
animal research laboratories due to the COVID-19 pandemic. We expect to receive preliminary results from this program during the first half of 2021.
In addition to the license agreement for the miniCEP290 program, UMMS has granted us an option to obtain an exclusive license to any patents or patent applications that result from any of these sponsored research programs.
Impact of COVID-19
Beginning in March 2020, the COVID-19 pandemic and measures taken to contain it have affected our business and operations in a number of ways. These include, but are not limited to, the following:
•In March 2020, we decided to delay the initiation of patient enrollment in our GATHER2 trial. Although we initiated patient enrollment in June 2020 and our clinical trial sites are continuing to enroll patients, we and our clinical trial sites are doing so cautiously in light of new health and safety practices put into place as a result of the COVID-19 pandemic. We are continuing to monitor the situation closely and may need to slow down or stop patient enrollment in certain geographies depending on the local situation. In addition, we have added sites to this trial because of the ongoing and variable nature of the pandemic and its potential impact on patient recruitment and retention. Health authorities and ethics committees in certain countries have reduced their staff and operations due to the COVID-19 pandemic. This reduction in operations has resulted in delays to the approval of our trial in certain countries outside the United States and delays in the activation process for a number of our planned clinical trial sites. We may face difficulties in recruiting or retaining patients or maintaining scheduled visits to the extent patients are affected by the virus or are fearful of visiting or traveling to our clinical trial sites because of the pandemic. We are aware that a number of patients initially enrolled in the STAR trial missed consecutive visits during the early months of the pandemic. We do not yet know whether the number of missed visits will increase or decrease among the newly enrolled patients in the STAR trial or how many missed visits will occur in the GATHER2 trial, or what the impact of missed visits may be on trial results, especially because we are masked to the treatment of patients during the conduct of the trials. At this time, we do not know whether there will be further impacts on the timing and progress of patient enrollment or on patient retention or maintenance of scheduled visits in any of our ongoing or planned clinical trials as a result of the COVID-19 pandemic.
•Although most of our clinical trial sites have reopened and are continuing to conduct patient visits for our clinical trials, they are doing so with fewer staff and other restrictions and many of them are focusing on more urgent matters rather than clinical trials. We are engaging with our clinical trial sites, with the goal of monitoring the health and well-being of our patients who remain in our trials and maintaining their scheduled visits and treatments. Where possible, we and our clinical investigators have instituted practices such as flexible scheduling of visits for patients and remote monitoring, and we have also provided patient travel services and personal protective equipment to support our sites and patients. Recently, a number of our clinical trial sites have been scaling back their operations because of recent surges in COVID-19 cases or new lockdown measures being imposed. We have been and will continue to monitor the situation closely.
•In some instances, our third-party contract manufacturers, academic research collaborators and contract research organizations have limited their operations and staff, which has resulted in delays to some of our manufacturing and research and development activities and limited our ability to be on site to oversee these activities. For example, the closure of animal research laboratories at the UMMS for several months during 2020 caused delays to the progress of, and to our timelines for receipt of data from, our collaborative gene therapy sponsored research programs. Additionally, we were unable to perform person-in-plant (PIP) observations on a number of critical manufacturing activities at our CDMO for IC-100 and IC-200, which caused minor delays to our manufacturing timelines for both product candidates. Furthermore, because of the COVID-19 pandemic and restrictions on remote auditing due to privacy and other concerns, we have experienced difficulties and delays in performing audits on most of our clinical trial sites.
•Shortages, delays and governmental restrictions arising from the COVID-19 pandemic have disrupted and may continue to disrupt the ability of our contract manufacturers to procure items, such as raw materials, that are essential for the manufacture of our product candidates. For example, during 2020, our contract manufacturer for IC-500 experienced a shortage in obtaining one of the critical raw materials that was sourced from China, which was caused by the shutdown of local suppliers and the slowdown in trade due to the COVID-19 pandemic. This shortage delayed our process development activities for the drug substance for IC-500 by a number of months. Additionally, there is increased demand for the vials we are planning to use for the fill/finish of Zimura drug product, which governments
126
and other companies intend to use for COVID-19 vaccines and medicines. This increased demand may limit our ability to obtain these vials for our own needs.
•We instituted company-wide remote working starting in March 2020 and expect to continue working remotely for the foreseeable future. We have been relying on remote means of working and communication both internally and externally. We are continuing to monitor and support the health and well-being of our employees and their productivity as remote working continues.
We do not believe that the COVID-19 pandemic, and our actions in response and the costs of those actions, have had a material impact on our financial position, results of operations, or cash flows for the three months or year ended December 31, 2020. The progression of the COVID-19 pandemic remains fluid and its impact on our business and operations remains uncertain. The full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition will depend on developments that are highly uncertain and cannot be accurately predicted, including new information that may emerge concerning COVID-19, the actions taken to contain it or lessen its impact and the economic impact on local, regional, national and international markets. If the delays and other disruptions due to the pandemic become prolonged or more extensive, then we may experience further delays or disruptions to our research and development programs and our financial position, results of operations or cash flows for future periods may be materially affected.
For further information on actual and potential impacts to us as a result of the COVID-19 pandemic, see the other sections of this Management's Discussion and Analysis of Results of Operations and Financial Position and the Risk Factors contained in this Annual Report on Form 10-K.
Business Development and Financing Activities
Beginning in 2017, we pursued a business development strategy focused on evaluating various available technologies to treat ophthalmic diseases, particularly those in the back of the eye, and exploring opportunities to obtain rights to additional products and product candidates employing these technologies. Our efforts resulted in the expansion of our research and development pipeline, including the addition of IC-100, IC-200 and IC-500 and a number of collaborative gene therapy sponsored research programs.
As we continue the development of our product candidates and programs and evaluate our overall strategic priorities, we will continue to pursue selective business development and financing opportunities that advance us toward our strategic goals. We continue to explore potential collaboration and out-licensing opportunities for the future development and potential commercialization of our product candidates. In addition, we plan to continue to evaluate, on a selective and targeted basis, opportunities to potentially obtain rights to additional product candidates and technologies for retinal diseases, including technologies that may complement our existing product candidates and other strategic lifecycle initiatives.
For information about our follow-on public offerings that we completed in December 2019 and June 2020, please see the Liquidity and Capital Resources section of Management' s Discussion and Analysis of Financial Condition and Results of Operations set forth in this Item 7. We expect to continue to pursue capital raising transactions when they are available on terms favorable to us and if the opportunity advances our strategic goals.
Financial Matters
As of December 31, 2020, we had cash, cash equivalents and available for sale securities of $210.0 million. We estimate that our year-end 2021 cash, cash equivalents and available for sale securities will range between $130 million and $140 million. We also estimate that our cash, cash equivalents and available for sale securities will be sufficient to fund our planned capital expenditure requirements and operating expenses, excluding any potential approval or sales milestones payable to Archemix or any commercialization expenses for Zimura, into 2024. These estimates are based on our current business plan, which includes the continuation of our ongoing clinical development programs for Zimura, the progression of our IC-100 and IC-200 programs into the clinic, and the advancement of our IC-500 development program. These estimates also assume that we will enroll approximately 400 patients in the GATHER2 trial. These estimates do not reflect any additional expenditures related to potentially studying Zimura in other indications, or resulting from the potential in-licensing or acquisition of additional product candidates or technologies, commencement of any new sponsored research programs, or any associated development we may pursue. We have based these estimates on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect.
127
Fovista
In December 2016 and August 2017, we received initial top-line data from our three pivotal clinical trials, referred to as OPH1002, OPH1003 and OPH1004, evaluating the anti-platelet derived growth factor, or anti-PDGF, aptamer Fovista® (pegpleranib) administered in combination with anti-VEGF agents for the treatment of wet AMD. These top-line data indicated that the trials failed to achieve their pre-specified primary endpoints. We terminated these trials, as well as several other smaller Fovista trials in wet AMD in 2017. We have no plans for the future development of Fovista.
Prior Novo Agreement
In May 2013, we entered into a Purchase and Sale Agreement with Novo Holdings A/S (formerly Novo A/S and which we refer to as Novo), which we refer to as the Novo Agreement, pursuant to which we obtained financing in three tranches in an aggregate amount equal to $125.0 million in return for the sale to Novo of aggregate royalties of a mid-single-digit percentage on worldwide sales of Fovista, certain products related to Fovista, as specified in the Novo Agreement, or Fovista-Related Products, and certain other PDGF antagonists which we might develop, as specified in the Novo Agreement, or Other Products. The three tranches of financing closed in May 2013, January 2014 and November 2014. We recorded the aggregate $125.0 million in proceeds that we received under the Novo Agreement as a royalty purchase liability on our Balance Sheet in accordance with Accounting Standards Codification, or ASC, 730, Research and Development, or ASC 730.
On December 31, 2018, we and Novo entered into a letter agreement, which we refer to as the Novo Termination Agreement, that terminated the Novo Agreement. As a result of the Novo Termination Agreement, Novo relinquished all rights to receive royalties based on net sales of Fovista, Fovista-Related Products and Other Products. In exchange, we agreed to forbear from any future filing, prosecution, maintenance or enforcement of any intellectual property rights related to Fovista, Fovista-Related Products or Other Products, and from granting any third party or affiliate any right or license in any such intellectual property rights or clinical study data generated by or on behalf of us, our affiliates, licensees or sublicensees, for the development, manufacture or commercialization of Fovista, Fovista-Related Products, Other Products or any other antagonists of PDGF. The foregoing restriction does not apply to gene therapies (so long as we do not grant any rights or licenses to intellectual property or clinical study data related to Fovista or Fovista-Related Products). We further agreed, until December 31, 2028, not to develop, manufacture, seek or obtain regulatory approval for or commercialize Fovista, Fovista-Related Products or Other Products without the prior written consent of Novo. The foregoing restriction does not apply to any gene therapies (so long as we do not utilize data related to Fovista or Fovista-Related Products).
Effective December 31, 2018, as a result of the Novo Termination Agreement, we extinguished the $125.0 million royalty purchase liability from our Balance Sheet as we no longer have any obligation to repay Novo the $125.0 million through future product royalties or any other development activities. In addition, we recognized a related gain of $125.0 million in our Statements of Operations for the year ended December 31, 2018. The extinguishment of the royalty purchase liability and the related gain did not impact our cash balance for that period as we had received the proceeds related to the royalty purchase liability in prior periods.
Financial Operations Overview
Revenue
As we have no products approved for sale, we do not expect to receive any revenue related to our product candidates until we obtain regulatory approval for and commercialize such products, or until we potentially enter into agreements with third parties for the development and commercialization of our product candidates. If our development efforts for any of our product candidates result in regulatory approval or if we enter into collaboration agreements with third parties, we may generate revenue from product sales or from such third parties.
Our ability to become and remain profitable depends on our ability to generate revenues in excess of our expenses. Our ability to generate revenues from product sales is dependent on our obtaining marketing approval for and commercializing our product candidates or any product candidates we may in-license or acquire. We may be unsuccessful in our efforts to develop and commercialize product candidates or in our efforts to in-license or acquire additional product candidates. Even if we succeed in developing and commercializing one or more of our product candidates, we may never achieve sufficient sales revenue to achieve or maintain profitability.
Research and Development Expenses
Our research and development expenses primarily consist of costs associated with the manufacturing, development, and preclinical and clinical testing of our product candidates and costs associated with our gene therapy sponsored research programs. Our research and development expenses consist of:
128
•external research and development expenses incurred under arrangements with third parties, such as academic research collaborators, contract research organizations, or CROs, and other vendors and CDMOs for the production and analysis of drug substance and drug product; and
•employee-related expenses for employees dedicated to research and development activities, including salaries, benefits and share-based compensation expense.
Research and development expenses also include costs of acquired product licenses, in-process research and development, and related technology rights where there is no alternative future use, costs of prototypes used in research and development, consultant fees and amounts paid to collaborative partners.
All research and development expenses are charged to operations as incurred in accordance with ASC 730. We account for non-refundable advance payments for goods and services that will be used in future research and development activities as expenses when the service has been performed or when the goods have been received, rather than when the payment is made. We do not currently utilize a formal time allocation system to capture expenses on a project-by-project basis because we record expenses by functional department. Accordingly, we do not allocate expenses to individual projects or product candidates, although we do allocate some portion of our research and development expenses by project area or product candidate, as shown below.
The following table summarizes our research and development expenses for the years ended December 31, 2020, 2019 and 2018:

As we continue our ongoing clinical trials and planned manufacturing activities for Zimura, we expect our research and development expenses for Zimura to increase. We also expect our research and development expenses for each of IC-100 and IC-200 to increase as we complete preclinical development and subject to regulatory review, begin clinical development for those product candidates. We expect our research and development expenses for IC-500 to increase as we continue preclinical development. We expect our research and development expenses for our other collaborative gene therapy sponsored research programs to decrease as the sponsored research for those programs reaches completion. Our research and development expenses may also increase if we decide to pursue the development of Zimura in additional indications, we in-license or acquire any new product candidates, including from our collaborative gene therapy sponsored research programs, or if we commence any new sponsored research programs.
Although the future development of our product candidates is highly uncertain, we expect the development of our product candidates will continue for at least the next several years. At this time, we cannot reasonably estimate the total remaining costs necessary to complete development, to complete process development and manufacturing scale-up and validation activities and to potentially seek marketing approval for any of our product candidates.
The successful development of our product candidates is subject to numerous risks and uncertainties associated with developing drugs, including the uncertainty of:
•the scope, rate of progress and costs of our research and development activities, including manufacturing activities;
•the potential benefits of our product candidates over other therapies;
129
•preclinical development results and clinical trial results;
•the terms and timing of regulatory approvals;
•our ability to market, commercialize and achieve market acceptance for any of our product candidates; and
•our ability to successfully file, prosecute, defend and enforce patent claims and other intellectual property rights, together with associated expenses.
A change in the outcome of any of these variables with respect to the development of our product candidates could mean a significant change in the costs and timing associated with the development of that product candidate. For example, we are conducting the GATHER2 trial, which is a Phase 3 clinical trial evaluating Zimura for GA, with the expectation that data collected from this trial, if positive, together with data from our GATHER1 trial, will be sufficient to seek marketing approval for this indication in the United States and the European Union. We may subsequently decide to, or be required by regulatory authorities to, enroll additional patients in the GATHER2 trial beyond our current expectations, conduct additional clinical trials for Zimura in GA or conduct additional non-clinical studies of Zimura in order to seek or maintain regulatory approval or qualify for reimbursement approval. As a result of any of the above, we could be required to expend significant additional financial resources and time on the completion of development of Zimura in GA.
See the “Liquidity and Capital Resources” section of this Item 7 of this Annual Report on Form 10-K for more information regarding our current and future financial resources and our expectations regarding our research and development expenses and funding requirements.
General and Administrative Expenses
General and administrative expenses consist primarily of salaries and related costs for personnel, including share-based compensation expense, in our executive, legal, finance, business development, human resources, investor relations and information technology functions. Other general and administrative expenses include facility costs and professional fees for legal, including patent-related, services and expenses, consulting and accounting services, and travel expenses.
Interest Income
We currently have invested our cash, cash equivalents and available for sale securities in money market funds, U.S. Treasury securities, asset-backed securities and investment-grade corporate debt securities, which generate a nominal amount of interest income.
Critical Accounting Policies and Significant Judgments and Estimates
Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which we have prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued research and development expenses, revenue recognition, share-based compensation and income taxes described in greater detail below. We base our estimates on our limited historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
Our significant accounting policies are described in more detail in the notes to our financial statements appearing elsewhere in this Annual Report on Form 10-K. Of those policies, we believe that the following accounting policies are the most critical to aid our stockholders in fully understanding and evaluating our financial condition and results of operations.
Accrued Research and Development Expenses
As part of the process of preparing our financial statements, we are required to estimate our accrued expenses. This process involves reviewing quotations and contracts, identifying services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us monthly in arrears for services performed or when contractual milestones are met. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our
130
estimates with the service providers and make adjustments if necessary. The significant estimates in our accrued research and development expenses are related to expenses related to our academic research collaborators, CROs, CDMOs and other vendors in connection with research and development and manufacturing activities.
We base our expenses related to academic research collaborators, CROs and CDMOs on our estimates of the services received and efforts expended pursuant to quotations and contracts with such vendors that conduct research and development and manufacturing activities on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the applicable research and development or manufacturing expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in us reporting amounts that are too high or too low in any particular period. There have been no material changes in estimates for the periods presented in this Annual Report on Form 10-K.
Share-Based Compensation
We account for all share-based compensation payments issued to employees, non-employee directors, and consultants by estimating the fair value of each equity award. Accordingly, share-based compensation expense is measured based on the estimated fair value of the awards on the date of grant, net of forfeitures. We recognize compensation expense for the portion of the award that is ultimately expected to vest over the period during which the recipient renders the required services to us on a straight-line basis. In accordance with authoritative guidance, we re-measure the fair value of consultant share-based awards as the awards vest, and recognize the resulting value, if any, as expense during the period when the related services are rendered.
We apply the fair value recognition provisions of ASC 718, Compensation—Stock Compensation. Determining the amount of share-based compensation to be recorded requires us to develop estimates of the fair value of stock options as of their grant date. We recognize share-based compensation expense ratably over the requisite service period, which in most cases is the vesting period of the award. For grants containing performance-based vesting provisions, expense is recognized over the estimated achievement period only when the performance-based milestone is deemed probable of achievement. If performance-based milestones are later determined not to be probable of achievement, then all previously recorded stock-based compensation expense associated with such options will be reversed during the period in which we make this determination. Calculating the fair value of share-based awards requires us to make highly subjective assumptions.
Prior to January 1, 2019, share-based compensation awarded to non-employees was subject to revaluation over the vesting term of each award. Subsequent to the adoption of ASU 2018-07, Improvements to Non-Employee Share-Based Payment Accounting, the value of non-employee share-based compensation is measured on the date of grant, similar to share-based compensation granted to employees.
We use the Black-Scholes option pricing model to value our stock option awards and the options to purchase shares under our employee stock purchase plan. Use of this valuation methodology requires that we make assumptions as to the volatility of our common stock, the expected term of our stock options, and the risk-free interest rate for a period that approximates the expected term of our stock options and the expected dividend yield of our common stock. We calculate expected volatility based on daily historical volatility during the time period that corresponds to the expected option term. We calculate the expected term of stock option grants to employees based on an analysis of actual option exercises. The risk-free interest rate used for each grant is based on the U.S. Treasury yield curve in effect at the time of grant for instruments with a similar expected life. We utilize a dividend yield of zero based on the fact that we have never paid cash dividends and have no current intention to pay cash dividends. The weighted-average assumptions used to estimate grant date fair value of stock options using the Black-Scholes option pricing model were as follows for the years ended December 31, 2020, 2019 and 2018:
| Years ended December 31, | |||||||||||||||||
| 2020 | 2019 | 2018 | |||||||||||||||
| Expected common stock price volatility | 118% | 110% | 85% | ||||||||||||||
| Risk-free interest rate - Low | 0.22 | 0.0138 | 0.0239 | ||||||||||||||
| Expected term of options (years) | 4.6 | 4.8 | 6.0 | ||||||||||||||
| Expected dividend yield | — | — | — | ||||||||||||||
131
We estimate the fair value of restricted stock units, or RSUs, granted to employees using the closing market price of our common stock on the date of grant.
We also estimate forfeitures at the time of grant, and revise those estimates in subsequent periods if actual forfeitures differ from our estimates. We use historical data to estimate pre-vesting forfeitures and record share-based compensation expense only for those awards that are expected to vest. To the extent that actual forfeitures differ from our estimates, the difference is recorded as a cumulative adjustment in the period when the estimates were revised.
Share-based compensation expense for equity grants to employees, non-employee directors and consultants was $8.3 million, $9.2 million and $11.1 million for the years ended December 31, 2020, 2019, and 2018, respectively. As of December 31, 2020, we had $23.2 million of total unrecognized share-based compensation expense, which we expect to recognize over a weighted-average remaining vesting period of approximately 3.4 years. We expect to grant additional stock options that will result in additional share-based compensation expense for our equity awards to employees, non-employee directors and consultants.
For the years ended December 31, 2020, 2019 and 2018, we allocated share-based compensation as follows:

In October 2019, our board of directors adopted the 2019 Inducement Stock Incentive Plan, or the Inducement Plan, pursuant to which we may grant, subject to the terms of the Inducement Plan and the rules of The Nasdaq Global Select Market, or Nasdaq, nonstatutory stock options, restricted stock, RSUs, and other stock-based awards up to an aggregate of 1,000,000 shares of our common stock. In March 2020, our board of directors amended the Inducement Plan to reserve an additional 1,000,000 shares of our common stock for issuance under the plan and in February 2021, our board of directors further amended the Inducement Plan to reserve an additional 600,000 shares of our common stock for issuance under the plan. The Inducement Plan permits us to, subject to the approval of each grant by the compensation committee of our board of directors, use the stock-based awards available under the Inducement Plan to attract key employees for the growth of our business. As of December 31, 2020, we had approximately 555,000 shares available for issuance under the Inducement Plan.

Research and Development Expenses
Our research and development expenses were $62.8 million for the year ended December 31, 2020, an increase of $23.1 million compared to $39.6 million for the year ended December 31, 2019. The increase in research and development expenses for the year ended December 31, 2020 was primarily due to a $15.1 million increase in costs associated with Zimura, a $6.6 million increase in personnel costs, a $3.1 million increase in costs associated with IC-200 and a $1.0 million increase in costs associated with IC-500 which were partially offset by a $0.8 million decrease in costs related to our prior Fovista manufacturing activities due to a sales tax refund, a $0.5 million decrease in costs associated with IC-100 and a $0.5 million decrease in costs associated with our collaborative gene therapy sponsored research programs. The increased costs for Zimura were primarily due to the initiation of and commencement of patient enrollment for our GATHER2 trial, increased manufacturing activities and the payment of a $6.0 million milestone to Archemix. The increased costs for IC-200 and IC-500 primarily reflect increased manufacturing and preclinical development activities.
General and Administrative Expenses
Our general and administrative expenses were $26.0 million for the year ended December 31, 2020, an increase of $4.3 million, compared to $21.6 million for the year ended December 31, 2019. The increase in general and administrative expenses was primarily due to an increase in general consulting costs and professional fees.
Interest Income
Interest income for the year ended December 31, 2020 was $0.5 million compared to interest income of $2.2 million for the year ended December 31, 2019. The decrease in interest income earned during the year ended December 31, 2020 was primarily due to the decrease in interest rate yields.
Income Tax Benefit
We recorded a benefit from income taxes of approximately $3.7 million and $0.1 million for the year ended December 31, 2020 and 2019, respectively, which primarily related to the settlement of local tax audits.

Research and Development Expenses
Our research and development expenses were $39.6 million for the year ended December 31, 2019, a decrease of $2.1 million compared to $41.7 million for the year ended December 31, 2018. The decrease in research and development expenses for the year ended December 31, 2019 was primarily due to a $6.4 million decrease in costs associated with our HtrA1 inhibitor program, a $3.9 million decrease in costs associated with our Zimura program and a $1.6 million decrease in professional services and consulting fees. The decreased costs for our HtrA1 inhibitor program related to the immediate expensing in 2018 of the in-process research and development costs of our HtrA1 inhibitor program acquired through our acquisition of Inception 4 in 2018. The decreased costs for our Zimura programs included lower costs related to a decrease in Zimura manufacturing
133
activities and lower clinical trial costs as a result of the completion of the OPH2007 trial during the fourth quarter of 2018 and the completion of patient recruitment for the OPH2003 trial during the fourth quarter of 2018 and the associated reduction in site initiation costs. The decreased costs for our Zimura programs were partially offset by increased costs associated with the continued progress of the OPH2005 trial. The overall decrease in research and development expenses was partially offset by a $9.4 million increase in costs resulting from the expansion of our gene therapy programs.
General and Administrative Expenses
Our general and administrative expenses were $21.6 million for the year ended December 31, 2019, a decrease of $2.0 million, compared to $23.6 million for the year ended December 31, 2018. The decrease in general and administrative expenses was primarily due to a decrease of $1.6 million in personnel expenses and a decrease of $0.5 million in professional and consulting fees. The decrease in personnel expenses included a decrease of $1.2 million in share-based compensation expense as a result of a decrease in the fair value of our common stock.
Interest Income
Interest income for the year ended December 31, 2019 was $2.2 million compared to interest income of $2.4 million for the year ended December 31, 2018. The decrease in interest income earned during the year ended December 31, 2019 was the result of a decrease in cash balances available for investment.
Gain on Extinguishment of Royalty Purchase Liability
On December 31, 2018 we entered into the Novo Termination Agreement, which terminated the Novo Agreement. As we no longer had an obligation to repay Novo the $125.0 million that it had provided us pursuant to the Novo Agreement, we extinguished the $125.0 million royalty purchase liability from our Balance Sheet as of December 31, 2018 and recognized a related gain of $125.0 million in our Statements of Operations for the year ended December 31, 2018. This gain on the extinguishment of the royalty purchase liability did not impact our cash balance during that period as we had received the proceeds related to the royalty purchase liability in prior periods.
Income Tax Benefit
We recorded a benefit from income taxes of approximately $0.1 million and $1.1 million for the year ended December 31, 2019 and 2018, respectively, which primarily related to the settlement of local tax audits.
Although we had net income before income taxes during 2018, this income is primarily due to the Novo Termination Agreement. Payments received under the Novo Agreement had previously been recorded as revenue on our federal and state income tax returns during the periods in which the payments were received. The recognition of income for financial statement purposes resulted in the reduction of a deferred tax asset that was completely offset by a previously recorded valuation allowance.
Liquidity and Capital Resources
Sources of Liquidity
Since inception, we have financed our operations primarily through private placements of our common stock and preferred stock, venture debt borrowings, funds received under the Novo Agreement, our initial public offering, which we closed in September 2013, funds we received under a prior agreement with Novartis Pharma AG relating to the licensing and commercialization of Fovista, funds we received in connection with our acquisition of Inception 4 in October 2018, and our follow-on public offerings, which we closed in February 2014, December 2019 and June 2020, including the sale of pre-funded warrants in December 2019 and June 2020. We do not have any committed external source of funds.
June 2020 Follow-on Public Offering and Concurrent Private Placement
In June 2020, we closed an underwritten public offering in which we sold 28,503,220 shares of our common stock, including the exercise in full of the underwriters’ option to purchase additional shares of our common stock, at a price to the public of $4.10 per share, and at a price to the underwriters of $3.854 per share. We also sold to certain investors in lieu of common stock, pre-funded warrants to purchase 1,914,280 shares of our common stock at a price to the public of $4.099 per share underlying each pre-funded warrant, and at a price to the underwriters of $3.853 per share underlying each pre-funded warrant.
Concurrently with the June 2020 public offering, we completed a private placement exempt from the registration requirements of the Securities Act of 1933, as amended, in which we sold 8,649,453 shares of our common stock to affiliates of Vivo Capital, LLC and Samsara BioCapital, LP, or the Private Placement Purchasers, at a purchase price equal to $4.10 per
134
share, the price to the public in the public offering. The shares in the private placement were issued pursuant to a stock purchase agreement entered into among us and the Private Placement Purchasers.
The net proceeds from the public offering and private placement, after deducting underwriting discounts, placement agent fees and other offering expenses of approximately $10.1 million, was approximately $150.1 million.
December 2019 Follow-on Public Offering
In December 2019, we completed an underwritten public offering in which we sold approximately 7,750,000 shares of our common stock, which includes the underwriters' option to purchase additional shares of our common stock, at a public offering price of $4.00 per share, and at a price per share of $3.736 to the underwriters. We also sold to certain investors pre-funded warrants to purchase 3,750,000 shares of our common stock at a public offering price of $3.999 per share underlying each warrant, and at a purchase price of $3.735 per share underlying each warrant to the underwriters.
The net proceeds from the offering, after deducting underwriting discounts and commissions of $3.0 million and other offering expenses of $0.4 million, was approximately $42.6 million.
Cash Flows
As of December 31, 2020, we had cash, cash equivalents and available for sale securities totaling $210.0 million and no debt. We primarily invest our cash, cash equivalents and available for sale securities in money market funds, U.S. Treasury securities, asset-backed securities and certain investment-grade corporate debt securities.
The following table shows a summary of our cash flows for the years ended December 31, 2020, 2019 and 2018:

Cash Flows from Operating Activities
The net cash used in operating activities, which was $66.1 million and $48.5 million for the years ended December 31, 2020 and 2019, respectively, relates primarily to net cash used to fund our Zimura clinical trials and manufacturing activities and to support the preclinical development activities of IC-100, IC-200 and IC-500.
See "—Funding Requirements" below for a description of how we expect to use our cash for operating activities in future periods.
Cash Flows from Investing Activities
Net cash used in investing activities was $143.8 million for the year ended December 31, 2020, which primarily related to the purchase of available for sale securities. Net cash provided by investing activities for the year ended December 31, 2019 was $0.2 million and related to the proceeds received from the sale of manufacturing and clinical equipment.
Cash Flows from Financing Activities
Net cash provided by financing activities for the year ended December 31, 2020 was $150.6 million and relates primarily to cash received from our June 2020 public offering of our common stock and concurrent private placement. Net cash provided by financing activities for the year ended December 31, 2019 was $42.8 million and relates primarily to cash received from our December 2019 public offering of our common stock.
Funding Requirements
Zimura is in clinical development, our gene therapy product candidates IC-100 and IC-200, and IC-500, the selected product candidate from our HtrA1 inhibitor program, are each in preclinical development, and we are funding multiple ongoing collaborative gene therapy sponsored research programs. We expect our research and development expenses to increase as we
135
pursue these programs as currently planned. We could incur additional research and development expenses if we modify or further expand the scope of our clinical trials, including if we develop Zimura for additional indications, preclinical development programs or collaborative gene therapy sponsored research programs, or if we in-license or acquire, and undertake development of, additional product candidates and technologies, including any promising product candidates that emerge from our collaborative gene therapy sponsored research programs. We could also incur additional research and development expenses if, for example, we are required by the FDA, the EMA, or regulatory authorities in other jurisdictions to perform clinical trials and nonclinical or other studies in addition to those we currently expect to conduct. If we experience delays or disruptions to our research and development programs, including delays in patient enrollment or issues with patient retention or patients missing scheduled visits and treatments, if we experience issues with our preclinical development programs, such as unfavorable toxicology or other preclinical data, if we experience issues with the manufacture and supply of product candidates for our development programs, including issues with process development or manufacturing scale-up activities, whether such delays or disruptions are due to the COVID-19 pandemic or other reasons, we could incur additional and unexpected expenses as a result of such delays or disruptions and our business and financial results may be materially impacted. Furthermore, if we successfully develop and expect to obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, distribution and manufacturing. We are party to agreements with Archemix Corp., or Archemix, with respect to Zimura, the University of Florida Research Foundation, Incorporated, or UFRF, and Penn with respect to IC-100 and IC-200, UMass with respect to any potential product candidates from our miniCEP290 program, and the former equityholders of Inception 4 with respect to IC-500, in each case, that impose significant milestone payment obligations on us if we achieve specified clinical, regulatory and commercial milestones with respect to these product candidates, as well as certain royalties on net sales with respect to IC-100, IC-200 and any product candidates we choose to develop from our miniCEP290 program. It is likely that any future in-licensing or acquisition agreements that we enter into with respect to additional product candidates or technologies would include similar obligations.
We expect that we will continue to incur significant expenses as we:
•continue the development of Zimura in GA, STGD1 and potentially other indications;
•expand our outsourced manufacturing activities or establish commercial operations or sales, marketing and distribution capabilities, if we receive, or expect to receive, marketing approval for any of our product candidates;
•continue the development of IC-100, IC-200 and IC-500 and pursue our collaborative gene therapy sponsored research programs;
•in-license or acquire the rights to, and pursue the development of, other product candidates or technologies;
•seek marketing approval for any product candidates that successfully complete clinical trials;
•maintain, expand and protect our intellectual property portfolio;
•hire additional clinical, commercial, medical affairs, regulatory, manufacturing, quality control, quality assurance and scientific personnel; and
•expand our general and administrative functions to support our future growth.
As of December 31, 2020, we had cash, cash equivalents and available for sale securities of $210.0 million. We estimate that our year-end 2021 cash, cash equivalents and available for sale securities will range between $130 million and $140 million. We also estimate that our cash, cash equivalents and available for sale securities will be sufficient to fund our planned capital expenditure requirements and operating expenses, excluding any potential approval or sales milestones payable to Archemix or any commercialization expenses for Zimura, into 2024. These estimates are based on our current business plan, which includes the continuation of our ongoing clinical development programs for Zimura, the progression of our IC-100 and IC-200 programs into the clinic, and the advancement of our IC-500 development program. These estimates also assume that we will enroll approximately 400 patients in the GATHER2 trial. These estimates do not reflect any additional expenditures related to potentially studying Zimura in other indications, or resulting from the potential in-licensing or acquisition of additional product candidates or technologies, commencement of any new sponsored research programs, or any associated development we may pursue. We have based these estimates on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect.
We expect we will require substantial, additional funding in order to complete the activities necessary to develop and commercialize one or more of our product candidates. Although the future development of our product candidates is highly uncertain, we expect the development of our product candidates will continue for at least the next several years. At this time, we
136
cannot reasonably estimate the total remaining costs necessary to complete development, to complete process development and manufacturing scale-up and validation activities and to potentially seek marketing approval for any of our product candidates.
Our future capital requirements will depend on many factors, including:
•the scope, progress, costs and results of our current and any future Zimura clinical programs and any further development we may undertake to enable us to file a new drug application, or NDA, for Zimura in one or more indications;
•the scope, costs, progress, and results of process development, manufacturing scale-up and validation activities, analytical method development and qualification, and stability studies associated with Zimura and our other product candidates;
•the scope, progress, costs and results of our efforts to develop IC-100, IC-200 and IC-500, including activities to establish manufacturing capabilities and other preclinical development activities to enable us to file INDs for these product candidates;
•the scope, progress, costs and results from our collaborative gene therapy sponsored research programs, including costs related to the in-license and future development of any promising product candidates and technologies that emerge from these programs;
•our ability to establish collaborations on favorable terms, if at all, if we choose to do so, including any collaboration for the further development and potential commercialization of any of our product candidates;
•the timing and extent of delays or disruptions to our research and development programs as a result of the COVID-19 pandemic;
•the extent to which we in-license or acquire rights to, and undertake research or development of, additional product candidates or technologies;
•the costs, timing and outcome of regulatory filings and reviews of our product candidates;
•the costs of preparing, filing and prosecuting patent applications, maintaining and protecting our intellectual property rights and defending intellectual property-related claims;
•the timing, scope and cost of commercialization activities for any of our product candidates if we receive, or expect to receive, marketing approval for a product candidate; and
•subject to receipt of marketing approval, net revenue received from commercial sales of any of our product candidates, after milestone payments and royalty payments that we would be obligated to make.
We may require additional funding beyond what we currently expect due to unforeseen or other reasons. Our costs may exceed our expectations if we experience an issue in our clinical trials, such as issues with patient enrollment, the retention of enrolled patients, enrolled patients maintaining scheduled visits and receiving scheduled treatments, or the availability of drug supply, if we experience an issue in our preclinical development programs, such as unfavorable toxicology or other preclinical data, if we experience issues with manufacturing, or if we modify or further expand the scope of our clinical trials, preclinical development programs or collaborative gene therapy sponsored research programs. For example, we have decided to enroll approximately 25 additional patients in our ongoing STAR trial, with the goal of enrolling a total of approximately 120 patients, which will extend the duration of that trial and increase our costs of conducting that trial. Our costs may also exceed our expectations for other reasons, for example, if we are required by the FDA, the EMA, or regulatory authorities in other jurisdictions to perform clinical trials or nonclinical or other studies in addition to those we currently expect to conduct, if we experience issues with process development, establishing or scaling-up of manufacturing activities or activities to enable and qualify second source suppliers, or if we decide to increase preclinical and clinical research and development activities, build internal research capabilities or pursue internal research efforts. For example, we are conducting the GATHER2 trial with the expectation that data collected from such trial, if it is positive, together with data from our GATHER1 trial, will be sufficient to support an application for marketing approval in the United States and the European Union and we may subsequently decide to, or be required by regulatory authorities to, enroll additional patients in the GATHER2 trial beyond our current expectations, conduct additional clinical trials for Zimura in GA or conduct additional non-clinical studies of Zimura in order to seek or maintain marketing approval or qualify for reimbursement approval. In addition, the COVID-19 pandemic may result in
137
disruptions to the progress of the GATHER2 trial or the STAR trial, including slowing patient enrollment or causing enrolled patients to miss their scheduled visits or drop out in greater numbers than we expect, or disruptions to our other research and development programs, which could cause us to continue to expend our cash resources while not progressing our research and development programs as expeditiously as we would have had the pandemic not occurred or persisted. We may experience difficulty in enrolling or retaining patients or maintaining scheduled visits and treatments due to patients' fears of visiting clinical trial sites or ongoing restrictive measures requiring social distancing or limiting travel. For example, we are aware that, in the STAR trial, a number of patients initially enrolled in the trial missed consecutive visits during the early months of the COVID-19 pandemic. We do not know yet whether the number of missed visits will increase or decrease among the newly enrolled patients in the STAR trial or how many missed visits will occur in the GATHER2 trial, and whether and to what extent missed visits may impact the results of any of the trials. As a result of any of the above, we may need or may seek to obtain additional funding for our continuing operations sooner or in greater amounts than expected.
We do not have any committed external source of funds. Our ability to raise adequate additional financing when needed, and on terms acceptable to us, will depend on many factors. These factors include investors' perceptions of the potential success of our ongoing business, including the development of our product candidates and other programs, and the potential future growth of our business. Additionally, these factors include general market conditions that also affect other companies. For example, the COVID-19 pandemic and governmental responses to the pandemic have caused volatility and uncertainty in the financial markets as well as additional volatility in the price of our stock, which may result in prospective investors being less likely to invest new capital. These factors may make raising capital difficult, and may result in us accepting terms that are unfavorable to us, especially if we are in need of financing at the particular time. Although we were able to raise approximately $150 million in net proceeds through our June 2020 public offering and concurrent private placement, we may not be able to successfully raise additional capital. The size of our company and our status as a company listed on The Nasdaq Global Select Market, or Nasdaq, may also limit our ability to raise financing. For example, our ability to raise adequate financing through a public offering may be limited by market conditions and SEC rules based on our current market capitalization. Nasdaq listing rules also generally limit the number of shares we may issue in a private placement to a number less than 20% of the number of shares of our common stock outstanding immediately prior to the transaction, unless we issue such shares at a premium, which investors may be unwilling to accept, or unless we obtain shareholder approval, which can be expensive and time-consuming and can add risk to our ability to complete the financing transaction. If we are unable to raise additional funds when needed, we may be required to delay, limit, reduce or terminate the development of one or more of our product candidates, our collaborative gene therapy sponsored research programs, or our future commercialization efforts.
Until such time, if ever, when we can generate substantial product revenues, we may need or may seek to finance our operations through a combination of equity offerings, debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans. To the extent that we raise additional capital through the sale of equity or convertible debt securities, our existing stockholders' ownership interests would be diluted, and the terms of these new securities may include liquidation or other preferences that adversely affect our existing stockholders' rights as common stockholders. The dilutive effect of future equity issuances may be substantial, depending on the price of our common stock at the time of such capital raise, with a lower stock price translating to greater dilution for existing stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, declaring dividends or entering into certain investments or transactions. In addition, we have issued, and may in the future issue additional, equity securities as consideration for business development transactions, which may also dilute our existing stockholders' ownership interests.
If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, products or product candidates or grant licenses on terms that may not be favorable to us. If we choose to pursue a collaboration for any of our product candidates, we may be required to relinquish certain valuable rights depending on the terms of such a transaction. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to grant rights to develop and market products or product candidates that we would otherwise prefer to develop and market ourselves.
Our need for additional financing may continue even if we are able to successfully develop one or more of our product candidates. Our future commercial revenues, if any, will be derived from sales of such product candidates, which may not be available for at least several years following completion of successful product development, if at all. In addition, if approved, our product candidates may not achieve commercial success. Even if those products are successful and we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Under most, if not all, of the foregoing circumstances, we may need to obtain substantial additional financing to achieve our business objectives.

Archemix C5 License Agreement
In September 2011, we entered into the C5 License Agreement with Archemix relating to anti-C5 aptamers. In connection with the C5 License Agreement, as amended, we paid Archemix an upfront licensing fee of $1.0 million and issued to Archemix an aggregate of 2,000,000 shares of our series A-1 preferred stock and 500,000 shares of our series B-1 preferred stock. We have paid Archemix an aggregate of $9.0 million in fees based on our achievement of specified clinical milestone events under the C5 License Agreement, including two milestone payments of $1.0 million and $6.0 million triggered by the positive 12-month data from, and by completion of, the GATHER1 trial, which we paid in March 2020 and October 2020, respectively.
Under the C5 License Agreement, for each anti-C5 aptamer product that we may develop under the agreement, including Zimura, we are obligated to make additional payments to Archemix of up to an aggregate of $50.5 million if we achieve specified development, clinical and regulatory milestones, with $24.5 million of such payments relating to a first indication, $23.5 million of such payments relating to second and third indications and $2.5 million of such payments relating to sustained delivery applications. Under the C5 License Agreement, we are also obligated to make additional payments to Archemix of up to an aggregate of $22.5 million if we achieve specified commercial milestones based on net product sales of all anti-C5 products licensed under the agreement. We are also obligated to pay Archemix a double-digit percentage of specified non-royalty payments we may receive from any sublicensee of our rights under the C5 License Agreement. We are not obligated to pay Archemix a running royalty based on net product sales in connection with the C5 License Agreement.
For more information about the C5 License Agreement, please see the section entitled "Licensing and Other Arrangements—Zimura - Archemix C5 License Agreement" in Part I, Item 1 of this Annual Report on Form 10-K.
Inception 4 Merger Agreement
In October 2018, we and Inception 4 entered into the Inception 4 Merger Agreement, pursuant to which we acquired IC-500 and our other HtrA1 inhibitors through a merger transaction. As part of the transaction, we received approximately $6.1 million in cash.
In addition, pursuant to the Inception 4 Merger Agreement, the former equityholders of Inception 4 will be entitled to receive contingent future payments from us based on the achievement of certain clinical and regulatory milestones of up to an aggregate maximum amount of $105 million, with $45 million of such potential payments relating to GA and $60 million of such potential payments relating to wet AMD. These future milestone payments will be payable in the form of shares of our common stock, calculated based on the price of our common stock over a five-trading day period preceding the achievement of the relevant milestone, unless and until the issuance of such shares would, together with all other shares issued in connection with the Inception 4 Merger, exceed an overall maximum limit of approximately 7.2 million shares, which is equal to 19.9% of the number of issued and outstanding shares of our common stock as of the close of business on the business day prior to the closing date of the Inception 4 Merger, and will be payable in cash thereafter.
For more information about the Inception 4 Merger Agreement, please see the section entitled "Licensing and Other Arrangements—IC-500 - Inception 4 Merger Agreement" in Part I, Item 1 of this Annual Report on Form 10-K.
RHO-adRP Gene Therapy Agreements with UFRF and Penn
RHO-adRP License Agreement
In June 2018, we paid a $0.5 million upfront license issuance fee to UFRF, on behalf of UFRF and Penn, in connection with entry into the RHO-adRP License Agreement, which was recorded as a research and development expense, as well as accrued patent prosecution expenses of approximately $30 thousand, which was recorded as a general and administrative expense. Under the agreement, we agreed to pay an annual license maintenance fee in the low double-digit thousands of dollars, which will be payable on an annual basis until the first commercial sale of a licensed product. In addition, we agreed to reimburse UFRF for the costs and expenses of patent prosecution and maintenance related to the licensed patent rights.
We further agreed to pay UFRF, on behalf of both licensors, up to an aggregate of $23.5 million if we achieve specified clinical, marketing approval and reimbursement approval milestones with respect to a licensed product and additionally, up to an aggregate of $70.0 million if we achieve specified commercial sales milestones with respect to a licensed product.
We are also obligated to pay UFRF, on behalf of both licensors, royalties at a low single-digit percentage of net sales of licensed products. Such royalties are subject to customary reductions for lack of patent coverage and loss of regulatory exclusivity. In addition, such royalties with respect to any licensed product in any country may be offset by a specified portion of any royalty payments actually paid by us with respect to such licensed product in such country under third-party licenses for
139
patent rights or other intellectual property rights that are necessary to manufacture, develop and commercialize the licensed product in such country. Our obligation to pay royalties under the RHO-adRP License Agreement will continue on a licensed product-by-licensed product and country-by-country basis until the latest of:
•the expiration of the last-to-expire licensed patent rights covering a licensed product in the country of sale;
•the expiration of regulatory exclusivity covering a licensed product in the country of sale; and
•ten years from the first commercial sale of the applicable licensed product in the country of sale.
Beginning on the earlier of the calendar year following the first commercial sale of a licensed product and the first business day of 2031, we are also obligated to pay certain minimum royalties, not to exceed an amount in the low hundreds of thousands of dollars on an annual basis, which minimum royalties are creditable against our royalty obligation with respect to net sales of licensed products due for the year in which the minimum royalty is paid.
If we or an affiliate sublicenses any of the licensed patent rights to a third party, we will be obligated to pay UFRF, on behalf of both licensors, a low double-digit percentage of the consideration received in exchange for such sublicense, with the applicable percentage based upon the stage of development of the sublicensed product at the time we or the applicable affiliate enters into the sublicense.
If we receive a rare pediatric disease priority review voucher from the FDA in connection with obtaining marketing approval for a licensed product and we subsequently use such priority review voucher in connection with a different product candidate, we will be obligated to pay UFRF, on behalf of both licensors, aggregate payments in the low double-digit millions of dollars based on certain marketing approval and commercial sales milestones with respect to such other product candidate. In addition, if we sell such a priority review voucher to a third party, we will be obligated to pay UFRF, on behalf of both licensors, a low double-digit percentage of any consideration received from such third party in connection with such sale.

RHO-adRP Master Sponsored Research Agreement
In June 2018, we also entered into a Master Sponsored Research Agreement, or the RHO-adRP Master SRA, with Penn. Under the RHO-adRP Master SRA, Penn has agreed to perform, on a project basis, certain sponsored research and to provide the results of such research to us. The scope of each project and certain associated terms, including financial terms, are to be specified in a statement of work for each project.
Under the RHO-adRP Master SRA, Penn has granted us an exclusive first option to obtain, for no additional consideration and pursuant to the terms of the RHO-adRP License Agreement, an exclusive license to any patents or patent applications resulting from the sponsored research that is fully-funded by us and that relate to the patent rights licensed under the RHO-adRP License Agreement. In addition, under the RHO-adRP Master SRA, Penn has granted us an exclusive first option to negotiate to acquire an exclusive license, on commercially reasonable terms, to any patents or patent applications resulting from the sponsored research that is not fully funded by us or do not relate to the patent rights licensed under the RHO-adRP License Agreement.
The initial term of the RHO-adRP Master SRA expires on June 6, 2021, provided that in the event of a termination of the RHO-adRP Master SRA, any statements of work in effect at the time of such termination shall continue in effect, subject to the terms of the RHO-adRP Master SRA, until expiration or termination of the applicable statement of work. Either party may terminate the RHO-adRP Master SRA or a statement of work if the other party breaches any of the terms or conditions of the RHO-adRP Master SRA or statement of work, as applicable, and does not cure such breach within a specified cure period. In addition, either party may terminate an applicable statement of work if the services of the applicable principal investigator are no longer available to Penn and an acceptable substitute is not appointed within an agreed-upon period. The RHO-adRP Master SRA contains indemnification and dispute resolution provisions that are customary for agreements of its kind.
We and Penn have entered into a series of statements of work under the RHO-adRP Master SRA pursuant to which Penn has conducted preclinical studies of IC-100 as well as a natural history study of RHO-adRP patients. The total amount of funding for the sponsored research covered by these statements of work that we have committed to date and are expecting to commit to is in the low single-digit millions of dollars.

BEST1 Gene Therapy Agreements with Penn and UFRF
BEST1 License Agreement
In May 2019, we paid Penn, for the benefit of Penn and UFRF, a $0.2 million upfront license issuance fee in connection with entry into the BEST1 License Agreement, which was recorded as a research and development expense, and we paid UFRF accrued patent prosecution expenses of approximately $18 thousand, which was recorded as a general and administrative expense. We have also agreed to pay Penn, for the benefit of Penn and UFRF, an annual license maintenance fee in the low double-digit thousands of dollars, which fee will be payable on an annual basis until the first commercial sale of a licensed product. In addition, we have agreed to pay Penn, for the benefit of Penn and UFRF, a one-time patent grant fee in the low triple-digit thousands of dollars, upon the issuance of a U.S. patent that claims inventions disclosed in the licensed patent rights or know-how or inventions generated under certain related sponsored research agreements with Penn or UFRF, and that is exclusively licensed to us. Furthermore, we have agreed to reimburse Penn and UFRF for the costs and expenses of patent prosecution and maintenance related to the licensed patent rights.
We have further agreed to pay Penn, for the benefit of Penn and UFRF, up to an aggregate of $15.7 million if we achieve specified clinical, marketing approval and reimbursement approval milestones with respect to one licensed product, and up to an aggregate of an additional $3.1 million if we achieve these same milestones with respect to a different licensed product. In addition, we have agreed to pay Penn, for the benefit of Penn and UFRF, up to an aggregate of $48.0 million if we achieve specified commercial sales milestones with respect to one licensed product, and up to an aggregate of an additional $9.6 million if we achieve these same milestones with respect to a different licensed product.
We are also obligated to pay Penn, for the benefit of Penn and UFRF, royalties at a low single-digit percentage of net sales of licensed products. Such royalties are subject to customary deductions, credits, and reductions for lack of patent coverage and loss of regulatory exclusivity. In addition, such royalties with respect to any licensed product in any country may be offset by a specified portion of any royalty payments actually paid by us with respect to such licensed product in such country under third-party licenses to patent rights or other intellectual property rights that are necessary to research, develop, manufacture and commercialize the licensed product in such country. Our obligation to pay royalties under the BEST1 License Agreement will continue on a licensed product-by-licensed product and country-by-country basis until the latest of:
•the expiration of the last-to-expire licensed patent rights covering the sale of the applicable licensed product in the country of sale;
•the expiration of regulatory exclusivity covering the applicable licensed product in the country of sale; and
•10 years from the first commercial sale of the applicable licensed product in the country of sale.
Beginning on the earlier of the calendar year following the first commercial sale of a licensed product and calendar year 2032, we are also obligated to pay certain minimum royalties, not to exceed an amount in the mid tens of thousands of dollars on an annual basis, which minimum royalties are creditable against our royalty obligation with respect to net sales of licensed products due in the year the minimum royalty is paid.
If we or any of our affiliates sublicense any of the licensed patent rights to a third party, we will be obligated to pay Penn, for the benefit of Penn and UFRF, a high single-digit to a mid ten's percentage of the consideration received in exchange for such sublicense, with the applicable percentage based upon the stage of development of the sublicensed product at the time we or the applicable affiliate enters into the sublicense.
If we receive a rare pediatric disease priority review voucher from the FDA in connection with obtaining marketing approval for a licensed product and we subsequently use such priority review voucher in connection with a different product candidate outside the scope of the BEST1 License Agreement, we will be obligated to pay Penn, for the benefit of Penn and UFRF, aggregate payments in the low double-digit millions of dollars based on certain approval and commercial sales milestones with respect to such other product candidate. In addition, if we sell such a priority review voucher to a third party, we will be obligated to pay Penn, for the benefit of Penn and UFRF, a high single-digit percentage of any consideration received from such third party in connection with such sale.
For more information about the BEST1 License Agreement, please see the section entitled "Licensing and Other Arrangements—License Agreement with Penn and UFRF for IC-200" in Part I, Item 1 of this Annual Report on Form 10-K.
BEST1 Master Sponsored Research Agreement
In October 2018, we entered into a master sponsored research agreement with Penn, which we refer to as the BEST1 Master SRA. Under the BEST1 Master SRA, Penn agreed to perform, on a project basis, certain sponsored research and to
141
provide the results of such research to us. The scope of each project and certain associated terms, including financial terms, are specified in a statement of work for each project.
Under the BEST1 Master SRA, Penn has granted us an exclusive first option to obtain, for no additional consideration and pursuant to the terms of the BEST1 License Agreement, an exclusive license to any patents or patent applications resulting from the sponsored research that is fully funded by us. In addition, under the BEST1 Master SRA, Penn has granted us an exclusive first option to negotiate to acquire an exclusive license, on commercially reasonable terms, to any patents or patent applications resulting from the sponsored research that is not fully funded by us.
The initial term of the BEST1 Master SRA expires on October 30, 2021, provided that in the event of a termination of the BEST1 Master SRA, any statements of work in effect at the time of such termination shall continue in effect, subject to the terms of the BEST1 Master SRA, until expiration or termination of the applicable statement of work. Either party may terminate the BEST1 Master SRA or a statement of work if the other party breaches any of the terms or conditions of the BEST1 Master SRA or statement of work, as applicable, and does not cure such breach within a specified cure period. In addition, either party may terminate an applicable statement of work if the services of the applicable principal investigator are no longer available to Penn and an acceptable substitute is not appointed within an agreed-upon period. The BEST1 Master SRA contains indemnification and dispute resolution provisions that are customary for agreements of this kind.
We and Penn have entered into a series of statements of work under the BEST1 Master SRA pursuant to which Penn is conducting preclinical studies of IC-200, as well as natural history studies of patients with BEST1-related IRDs. The total amount of funding for the sponsored research covered by these statements of work that we have committed to date and expect to commit to is in the low single-digit millions of dollars.
miniCEP290 License Agreement with UMass
In July 2019, we issued to UMass 75,000 shares of our common stock following execution of the miniCEP290 License Agreement pursuant to an exemption from registration afforded by Section 4(a)(2) of the Securities Act. In September 2019, we paid UMass a $0.4 million upfront license fee, which was recorded as a research and development expense, and we paid UMass accrued patent prosecution expenses of approximately $18 thousand, which was recorded as a general and administrative expense.
We have also agreed to pay UMass an annual license maintenance fee in the low double-digit thousands of dollars, which fee will be payable on an annual basis until the expiration of the royalty term for the licensed products. Furthermore, we have agreed to reimburse UMass for the costs and expenses of patent prosecution and maintenance related to the licensed patent rights.
We have further agreed to pay UMass up to an aggregate of $14.75 million in cash and issue up to 75,000 shares of our common stock if we achieve specified clinical and regulatory milestones with respect to a licensed product. In addition, we have agreed to pay UMass up to an aggregate of $48.0 million if we achieve specified commercial sales milestones with respect to a licensed product.
We are also obligated to pay UMass royalties at a low single-digit percentage of net sales of licensed products. Our obligation to pay royalties under the miniCEP290 License Agreement will continue on a licensed product-by-licensed product and country-by-country basis until the later of: (a) the expiration of the last-to-expire licensed patent rights covering the sale of the applicable licensed product in the country of sale, or (b) 10 years from the first commercial sale of the applicable licensed product in the country of sale. Beginning with the calendar year following receipt of marketing approval for a licensed product, we are also obligated to pay certain minimum royalties, not to exceed an amount in the mid-double-digit thousands of dollars on an annual basis, which minimum royalties are creditable against our royalty obligation with respect to net sales of licensed products due in the year the minimum royalty is paid.
If we or any of our affiliates sublicenses any of the licensed patent rights or know-how to a third party, we will be obligated to pay UMass a high single-digit to a mid-tens percentage of the consideration received in exchange for such sublicense, with the applicable percentage based upon the stage of development of the licensed products at the time we or the applicable affiliate enters into the sublicense.
If we receive a rare pediatric disease priority review voucher, or a priority review voucher, from the FDA in connection with obtaining marketing approval for a licensed product, and we subsequently use such priority review voucher in connection with a different product candidate outside the scope of the miniCEP290 License Agreement, we will be obligated to pay UMass a low-tens percentage of the fair market value of the priority review voucher at the time of approval of such product
142
candidate and a low-twenties percentage of the fair market value of the priority review voucher at the time of achievement of a specified commercial sales milestone for such other product candidate. In addition, if we sell such a priority review voucher to a third party, we will be obligated to pay UMass a low-thirties percentage of any consideration received from such third party in connection with such sale.
For more information about the minicCEP290 License Agreement, please see the section entitled "Licensing and Other Arrangements—License Agreement with UMass for miniCEP290 Program" in Part I, Item 1 of this Annual Report on Form 10-K.

(1)This item includes our contracted obligations under our sponsored research agreements.
(2)This item includes our contractual commitments under certain of our manufacturing and supply agreements.
(3)This table does not include:
•any milestone payments which may become payable to third parties under license or acquisition agreements as the timing and likelihood of such payments are not known with certainty;
•any royalty payments to third parties as the amounts, timing and likelihood of such payments are not known;
•anticipated expenditures under supply agreements for periods for which we are not yet bound under binding purchase orders; or
•contracts that are entered into in the ordinary course of business that are not material in the aggregate in any period presented above.
In addition to the amounts set forth in the table above, we may be required, under the agreements under which we acquired rights to Zimura, IC-100, IC-200, IC-500 and our miniCEP290 program, to make milestone payments and/or pay royalties. These payments are described in further detail in the descriptions of the applicable agreements set forth in this section.
We also have letter agreements with certain employees that require the funding of a specific level of payments, if certain events, such as a termination of employment in connection with a change in control or termination of employment by the employee for good reason or by us without cause, occur. For a description of these obligations, see our definitive proxy statement on Schedule 14A for our 2020 annual meeting of stockholders, as filed with the SEC on April 28, 2020.
In addition, in the course of normal business operations, we have agreements with contract service providers to assist in the performance of our research and development and manufacturing activities. Expenditures to CROs and CDMOs represent significant costs in preclinical and clinical development. Subject to required notice periods and our obligations under binding purchase orders and any cancellation fees that we may be obligated to pay, we can elect to discontinue the work under these agreements at any time. We may also enter into additional collaborative research, contract research, manufacturing, and supplier agreements in the future, which may require upfront payments and/or long-term commitments of cash.
Off-Balance Sheet Arrangements
We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under SEC rules.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.
We are exposed to market risk related to changes in interest rates. We had cash, cash equivalents and available for sale securities of $210.0 million as of December 31, 2020, consisting of cash and investments in money market funds, U.S. Treasury securities, corporate debt securities and asset-based securities. Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because a significant portion of our investments are in short-term securities. Due to the low risk profile of our investments, an immediate 100 basis point change in interest rates would not have a material effect on the fair market value of our portfolio.
We contract with CROs, CDMOs and certain other vendors to perform services outside the United States. We may be subject to fluctuations in foreign currency rates in connection with certain of these agreements. Transactions denominated in currencies other than the U.S. dollar are recorded based on exchange rates at the time such transactions arise. As of December 31, 2020, substantially all of our total liabilities were denominated in the U.S. dollar.
Item 8. Financial Statements and Supplementary Data
Our financial statements, together with the report of our independent registered public accounting firm, appear on pages F-2 through F-35 of this Annual Report on Form 10-K.
Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
None.
Item 9A. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2020. The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
Based on the evaluation of our disclosure controls and procedures as of December 31, 2020, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.
Management's Annual Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed by, or under the supervision of our Chief Executive Officer and our Chief Financial Officer, and effected by our board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate.
Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2020. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in the original Internal Control—Integrated Framework updated in 2013. Based on that assessment, our management concluded that, as of December 31, 2020, our internal control over financial reporting was effective.
The effectiveness of the Company's internal control over financial reporting as of December 31, 2020, has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which appears herein.
144
Changes in Internal Control Over Financial Reporting
No changes occurred in our internal control over financial reporting (as defined in Rules 13a-15(d) and 15d-15(d) under the Exchange Act) during the quarter ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Further, we have not experienced any material impact to our internal controls over financial reporting as a result of our employees working remotely due to the COVID-19 pandemic. We are continually monitoring and assessing the impact the COVID-19 pandemic has on the operating effectiveness of our internal controls.

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of IVERIC bio, Inc.
Opinion on Internal Control Over Financial Reporting
We have audited IVERIC bio, Inc.’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, IVERIC bio, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2020 and 2019, and the consolidated statements of operations, comprehensive income (loss), stockholders' equity and cash flows for each of the three years in the period ended December 31, 2020 and the related notes and our report dated March 4, 2021 expressed an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

INDEX TO CONSOLIDATED FINANCIAL STATEMENTS
F-1
Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of IVERIC bio, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of IVERIC bio, Inc. (the Company) as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive income (loss), stockholders' equity and cash flows for each of the three years in the period ended December 31, 2020 and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated March 4, 2021 expressed an unqualified opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
| Accrued research and development costs | |||||
| Description of the Matter | During 2020, the Company incurred $63 million of research and development expenses and accrued $13 million for research and development expenses as of December 31, 2020. As described in Note 2 to the Financial Statements, service agreements with third party service providers including contract research organizations (“CROs”) and contract development and manufacturing organizations (“CMOs”) comprise a significant component of the Company’s research and development activities. The timing and the amount of payments required under each individual arrangement are often different from the pattern of costs actually incurred. The Company accrues the cost of the services with these third-party organizations based on the extent of activities completed by vendors and measured by internal project managers. | ||||
Auditing management’s accounting for accrued contract research and development expenses is especially challenging because amounts owed to third parties are accrued based upon estimates of the proportion of work completed for each of the individual clinical trial and manufacturing activities in accordance with the unique terms and conditions of each respective CRO and CMO agreement. Estimating the proportion of work completed requires the application of judgments by management that are dependent on inputs, such as the number of sites activated, the number of patients enrolled and the number of patient visits, obtained from clinical personnel and third-party service providers and compiled from multiple sources.
F-2
|
How We Addressed the Matter in Our Audit
|
We obtained an understanding, evaluated the design, and tested the operating effectiveness of internal controls over the completeness and valuation of accrued research and development expenses, including controls over the judgments made by management and the data obtained from clinical personnel and third-party service providers.
|
||||
To test the research and development accrual, our audit procedures included, among others, testing the accuracy and completeness of the underlying data used in the estimates and evaluating the estimated proportion of work completed for each of the individual clinical trial and manufacturing activities used by management to estimate the recorded accruals. We inspected the contracts and any amendments to the contracts with third-party service providers, assessed the progress of clinical trials and other research and development projects with the Company’s research and development personnel that oversee the clinical trials, and obtained information directly from third parties, which included the third parties’ estimates of costs incurred to date. We also inspected subsequent invoices received from third parties.

We have served as the Company’s auditor since 2008.

1. Business
Description of Business and Organization
IVERIC bio, Inc. (the “Company” or “IVERIC”) is a science-driven biopharmaceutical company focused on the discovery and development of novel treatment options for retinal diseases with significant unmet medical needs. The Company is currently developing both therapeutic product candidates for age-related retinal diseases and gene therapy product candidates for orphan inherited retinal diseases ("IRDs"). The Company believes that both therapeutics and gene therapy serve important roles in drug development and providing potential treatment options for patients suffering from retinal diseases.
The Company's therapeutics portfolio consists of Zimura® (avacincaptad pegol), a complement C5 inhibitor, and its preclinical product candidate IC-500, a High temperature requirement A serine peptidase 1 protein ("HtrA1") inhibitor. The Company is targeting the following diseases with Zimura:
•Geographic Atrophy ("GA"), which is the advanced stage of age-related macular degeneration ("AMD"), and is characterized by marked thinning or atrophy of retinal tissue, leading to irreversible loss of vision; and
•autosomal recessive Stargardt disease ("STGD1"), which is an orphan inherited condition characterized by progressive damage to the central portion of the retina (the "macula") and other retinal tissue, leading to loss of vision.
The Company previously also evaluated Zimura in combination with Lucentis® (ranibizumab), an anti-vascular endothelial growth factor ("anti-VEGF") agent, for the treatment of wet AMD, for which the Company completed a Phase 2a clinical trial during the fourth quarter of 2018. The Company is developing IC-500 for GA secondary to AMD and potentially other age-related retinal diseases.
The Company's gene therapy portfolio consists of two product candidates in preclinical development (IC-100 and IC-200) and several ongoing research and development programs, each of which uses adeno-associated virus ("AAV") for gene delivery. These AAV mediated gene therapy programs are targeting the following orphan IRDs:
•rhodopsin-mediated autosomal dominant retinitis pigmentosa ("RHO-adRP"), which is characterized by progressive and severe bilateral loss of vision leading to blindness;
•IRDs associated with mutations in the BEST1 gene, including Best vitelliform macular dystrophy ("Best disease"), which is generally characterized by bilateral egg yolk-like lesions in the macula, which, over time, progress to atrophy and loss of vision;
•Leber Congenital Amaurosis type 10 ("LCA10"), which is characterized by severe bilateral loss of vision at or soon after birth;
•autosomal recessive Stargardt disease; and
•IRDs associated with mutations in the USH2A gene, which include Usher syndrome type 2A and USH2A-associated nonsyndromatic autosomal recessive retinitis pigmentosa.
The Company is developing IC-100 for RHO-adRP and IC-200 for BEST1-related IRDs.
2. Summary of Significant Accounting Policies
Basis of Presentation and Consolidation
The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and include all adjustments necessary for the fair presentation of

Notes to Financial Statements (Continued)
(tabular dollars and shares in thousands, except per share data)
2. Summary of Significant Accounting Policies (Continued)
the Company's financial position for the periods presented. The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Segment and geographic information
Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business in one operating and reporting segment.
Use of Estimates
The preparation of financial statements and related disclosures in conformity with GAAP requires management to make estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. The Company bases its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. The amounts of assets and liabilities reported in the Company's Consolidated Balance Sheets and the amount of expenses reported for each of the periods presented are affected by estimates and assumptions, which are used for, but not limited to, accounting for research and development costs, accounting for share-based compensation and accounting for income taxes. Actual results could differ from those estimates.
Cash, Cash Equivalents and Available for Sale Securities
The Company considers all highly liquid investments with an original maturity of 90 days or less when purchased to be cash equivalents. The carrying amounts reported in the Balance Sheets for cash and cash equivalents are valued at cost, which approximates their fair value.
The Company considers securities with original maturities of greater than 90 days to be available for sale securities. Available for sale securities with original maturities of greater than one year are recorded as non-current assets. Available for sale securities are recorded at fair value and unrealized gains and losses are recorded within other comprehensive income.
On a quarterly basis, the Company reviews the status of each security in an unrealized loss position, to evaluate the existence of potential credit losses. The Company first considers whether it intends to sell, or if it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For securities that do not meet this criteria, the Company considers a number of factors to determine if the decline in fair value has resulted from credit losses or other factors, including but not limited to: (1) the extent of the decline; (2) changes to the rating of the security by a rating agency; (3) any adverse conditions specific to the security; and (4) other market conditions that may affect the fair value of the security. If this assessment indicates that a credit loss exists and the present value of cash flows expected to be collected is less than the amortized cost basis, an allowance for credit losses is required for the credit loss. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income.
As of December 31, 2020, the Company had cash, cash equivalents and available for sale securities of approximately $210.0 million. The Company believes that its cash, cash equivalents and available for sale securities as of December 31, 2020 will be sufficient to fund its operations and capital expenditure requirements as currently planned for at least the next 12 months from the filing of the Company's Annual Report on Form 10-K.
Concentration of Credit Risk
The Company's financial instruments that are exposed to concentration of credit risk consist primarily of cash, cash equivalents and available for sale securities. The Company maintains its cash in bank accounts, the balance of which generally exceed federally insured limits. The Company maintains its cash equivalents and available for sale securities in investments in money market funds, in U.S. Treasury securities and asset-backed securities and investment-grade corporate debt securities with original maturities of 90 days or less.
The Company believes it is not exposed to significant credit risk on its cash and cash equivalents.

(tabular dollars and shares in thousands, except per share data)
2. Summary of Significant Accounting Policies (Continued)
Concentration of Suppliers
The Company historically relied upon a single third-party manufacturer to provide the drug substance for Zimura on a purchase order basis. The Company also historically relied upon a single third-party manufacturer to provide fill/finish services for clinical supplies of Zimura. The Company has engaged one additional third-party manufacturer to provide drug substance for Zimura and one additional third-party manufacturer to provide fill/finish services for clinical supplies of Zimura. In addition, the Company currently relies upon a single third-party supplier to supply on a purchase order basis the polyethylene glycol starting material used to manufacture Zimura. Furthermore, the Company and its contract manufacturers currently rely upon sole-source suppliers of certain raw materials and other specialized components of production used in the manufacture and fill/finish of Zimura. The Company currently relies exclusively upon a single third-party contract manufacturer for IC-100 and IC-200, and also relies on sole-source suppliers for certain starting materials used in the manufacture of such product candidates. The Company currently relies upon a single third-party contract manufacturer to conduct process development, scale-up and GMP manufacture of the drug substance for IC-500 for preclinical toxicology studies and early-stage clinical trials and a single third-party contract manufacturer to conduct formulation development activities for IC-500. If the Company’s third-party manufacturers or fill/finish service providers should become unavailable to the Company for any reason, including as a result of capacity constraints, different business objectives, financial difficulties, insolvency or the COVID-19 pandemic, the Company believes that there are a limited number of potential replacement manufacturers, and the Company likely would incur added costs and delays in identifying or qualifying such replacements.
Foreign Currency Translation
The Company considers the U.S. dollar to be its functional currency. Expenses denominated in foreign currencies are translated at the exchange rate on the date the expense is incurred. The effect of exchange rate fluctuations on translating foreign currency assets and liabilities into U.S. dollars is included in the Consolidated Statements of Operations and Comprehensive Loss. Foreign exchange transaction gains and losses are included in the results of operations and are not material in the Company's financial statements.
Financial Instruments
Cash equivalents are reflected in the accompanying financial statements at fair value. The carrying amount of accounts payable and accrued expenses, including accrued research and development expenses, approximates fair value due to the short-term nature of those instruments.
ASC 820, Fair Value Measurements and Disclosures, defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The fair value standard also establishes a three-level hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.
The Company reviews investments on a periodic basis for other than temporary impairments. This review is subjective as it requires management to evaluate whether an event or change in circumstances has occurred in the period that may have a significant adverse effect on the fair value of the investment. The Company uses the market approach to measure fair value for its financial assets. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets. The Company classifies its corporate debt securities within the fair value hierarchy as Level 2 assets, as it primarily utilizes quoted market prices or rates for similar instruments to value these securities.
Leases
The Company determines if an arrangement contains a lease at inception. For arrangements where the Company is the lessee, it recognizes a right-to-use ("ROU") lease asset and operating lease liability on the Company's Consolidated Balance Sheet. ROU lease assets represent the Company's right to use the underlying asset for the lease term and the lease obligation represents the Company's commitment to make the lease payments arising from the lease. Right-of-use lease assets and obligations are recognized at the commencement date based on the present value of remaining lease payments over the lease term. As the Company’s leases do not provide an implicit discount rate, the Company has used an estimated incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The ROU lease asset includes any lease payments made prior to commencement and excludes any lease incentives.

2. Summary of Significant Accounting Policies (Continued)
The lease term may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense is recognized on a straight-line basis over the lease term, subject to any changes in the lease or expectations regarding the terms. Variable lease costs such as common area costs and property taxes are expensed as incurred. For all office lease agreements the Company combines lease and nonlease components. Leases with an initial term of 12 months or less are not recorded on the Company's Consolidated Balance Sheet.
Property and Equipment
Property and equipment, which consists mainly of clinical equipment, computers, software, other office equipment, and leasehold improvements, are carried at cost less accumulated depreciation. Depreciation is computed over the estimated useful lives of the respective assets, generally three to ten years, using the straight-line method. Amortization of leasehold improvements is recorded over the shorter of the lease term or estimated useful life of the related asset.
Research and Development
The Company's research and development expenses primarily consist of costs associated with the manufacturing, development, and preclinical and clinical testing of the Company's product candidates and costs associated with its collaborative gene therapy sponsored research programs. The Company's research and development expenses consist of:
•external research and development expenses incurred under arrangements with third parties, such as academic research collaborators, contract research organizations ("CROs") and contract development and manufacturing organizations ("CDMOs") and other vendors for the production and analysis of drug substance and drug product; and
•employee-related expenses for employees dedicated to research and development activities, including salaries, benefits and share-based compensation expense.
Research and development expenses also include costs of acquired product licenses, in-process research and development, and related technology rights where there is no alternative future use, costs of prototypes used in research and development, consultant fees and amounts paid to collaborators.
All research and development expenses are charged to operations as incurred in accordance with ASC 730, Research and Development. The Company accounts for non-refundable advance payments for goods and services that will be used in future research and development activities as expenses when the service has been performed or when the goods have been received, rather than when the payment is made.
Income Taxes
The Company utilizes the liability method of accounting for deferred income taxes, as set forth in ASC 740, Income Taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. A valuation allowance is established against deferred tax assets when, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company's policy is to record interest and penalties on uncertain tax positions as income tax expense.
Share-Based Compensation
The Company follows the provisions of ASC 718, Compensation—Stock Compensation, which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and non-employee directors and consultants, including employee stock options, restricted stock units (“RSUs”) and options granted to employees to purchase shares under the 2016 Employee Stock Purchase Plan (the “ESPP”). Share-based compensation expense is based on the grant date fair value estimated in accordance with the provisions of ASC 718 and is generally recognized as an expense over the requisite service period, net of estimated forfeitures. For grants containing performance-based vesting provisions, expense is recognized over the estimated achievement period only when the performance-based milestone is deemed probable of achievement. If performance-based milestones are later determined not to be probable of achievement,

2. Summary of Significant Accounting Policies (Continued)
then all previously recorded stock-based compensation expense associated with such options will be reversed during the period in which the Company makes this determination.
The Company estimates forfeitures at the time of grant and revises those estimates in subsequent periods if actual forfeitures differ from its estimates. The Company uses historical data to estimate pre-vesting forfeitures and record share-based compensation expense only for those awards that are expected to vest. To the extent that actual forfeitures differ from the Company's estimates, the difference is recorded as a cumulative adjustment in the period the estimates were revised.
Stock Options
The Company estimates the fair value of stock options granted to employees, non-employees and non-employee directors on the date of grant using the Black-Scholes option-pricing model. The Company's computation of stock-price volatility is based on daily historical volatility during the time period that corresponds to the expected option term. The Company's computation of expected term is determined using the expected term of stock option grants to employees based on an analysis of actual option exercises. The Company utilizes a dividend yield of zero based on the fact that the Company has never paid cash dividends to stockholders and has no current intentions to pay cash dividends. The risk-free interest rate is based on the zero-coupon U.S. Treasury yield at the date of grant for a term equivalent to the expected term of the option.
The weighted-average assumptions used to estimate grant date fair value of stock options using the Black-Scholes option pricing model were as follows for the years ended December 31, 2020, 2019 and 2018:
| Years ended December 31, | |||||||||||||||||

| Expected dividend yield | — | — | — | ||||||||||||||
RSUs
The Company estimates the fair value of RSUs granted to employees using the closing market price of the Company's common stock on the date of grant.
ESPP
In April 2016, the Company's board of directors adopted the ESPP pursuant to which the Company may sell up to an aggregate of 1,000,000 shares of its common stock. The ESPP was approved by the Company’s stockholders in June 2016. The ESPP is considered compensatory and the fair value of the discount and look back provision are estimated using the Black-Scholes option-pricing model and recognized over the six month withholding period prior to purchase.
Share-based compensation expense includes expenses related to stock options and RSUs granted to employees, non-employee directors and consultants, as well as the option granted to employees to purchase shares under the ESPP, all of which have been reported in the Company’s Statements of Operations as follows:

Recently Adopted Accounting Pronouncements
In June 2016, the Financial Accounting Standards Board (the "FASB") issued Accounting Standard Update ("ASU") 2016-13 Financial Instruments (Topic 326) Measurement of Credit Losses on Financial Instrument (“CECL”). ASU 2016-13 requires an allowance for expected credit losses on financial assets be recognized as early as day one of the instrument. This ASU departs from the incurred loss model which means the probability threshold is removed. It considers more forward-looking information and requires the entity to estimate its credit losses as far as it can reasonably estimate. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted this accounting standard effective January 1, 2020 with no material impact to its financial statements.
In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), which modifies the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement, including, among other changes, the consideration of costs and benefits when evaluating disclosure requirements. For public companies, the amendments became effective for annual reporting periods beginning after December 15, 2019, including interim periods within those annual periods. The Company adopted this accounting standard effective January 1, 2020 with no material impact to its financial statements.
In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force). ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This guidance became effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. The Company adopted this accounting standard effective January 1, 2020 with no material impact to its financial statements.
In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808), which clarifies the interaction between the guidance for collaborative arrangements (Topic 808) and the new revenue recognition standard (Topic 606). For public companies, the amendments became effective for annual reporting periods beginning after December 15, 2019, including interim periods within those annual periods. The Company adopted this accounting standard effective January 1, 2020 with no material impact to its financial statements.
In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. ASU 2019-12 is effective for fiscal years beginning after December 15, 2021. Most amendments within the standard are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. The Company adopted this accounting standard effective January 1, 2020 with no material impact to its financial statements.
3. Common Stock
June 2020 Public Offering and Private Placement
In June 2020, the Company closed an underwritten public offering in which it sold 28,503,220 shares of its common stock, which includes the exercise in full of the underwriters’ option to purchase additional shares of its common stock, at a price to the public of $4.10 per share, and at a price to the underwriters of $3.854 per share. The Company also sold to certain investors in lieu of common stock, pre-funded warrants to purchase 1,914,280 shares of its common stock at a price to the public of $4.099 per share underlying each pre-funded warrant, and at a price to the underwriters of $3.853 per share underlying each pre-funded warrant. The pre-funded warrants are immediately exercisable with certain restrictions and do not expire.
Concurrently with the June 2020 public offering, the Company completed a private placement exempt from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"), in which it sold 8,649,453 shares of its common stock to affiliates of Vivo Capital, LLC and Samsara BioCapital, LP (the "Private Placement Purchasers"), at a

purchase price equal to $4.10 per share, which is the price to the public in the public offering. The shares in the private placement were issued pursuant to a stock purchase agreement entered into among the Company and the Private Placement Purchasers.
The net proceeds from the public offering and private placement, after deducting underwriting discounts, placement agent fees and other offering expenses of approximately $10.1 million, was approximately $150.1 million.
December 2019 Public Offering
On December 6, 2019, the Company completed an underwritten public offering in which it sold 6,250,000 shares of its common stock at a public offering price of $4.00 per share, and it sold to certain investors pre-funded warrants to purchase 3,750,000 shares of its common stock at a public offering price of $3.999 per share underlying each warrant. The offering included an option for the underwriters to purchase up to an additional 1,500,000 shares of its common stock, which was subsequently exercised in full by the underwriters. The shares of its common stock were sold to the underwriters at a purchase price of $3.736 per share and the pre-funded warrants were sold to the underwriters at a purchase price of $3.735 per share underlying each warrant. The pre-funded warrants are immediately exercisable with certain restrictions and do not expire.
The net proceeds from the offering, after deducting underwriting discounts and commissions of $3.0 million and other offering expenses of $0.4 million, was approximately $42.6 million.
The Company evaluated the pre-funded warrants for liability or equity classification in accordance with the provisions of ASC 480, Distinguishing Liabilities from Equity, and ASC 815-40, Derivatives and Hedging. Based on the provisions governing the pre-funded warrants in the applicable agreement, the Company determined that the pre-funded warrants meet the criteria required to be classified as an equity award subject to the guidance in ASC 815-10 and 815-40 and should effectively be treated as outstanding common shares in both basic and diluted EPS calculations.
miniCEP290 Program - University of Massachusetts
On July 22, 2019, the Company entered into its exclusive license agreement with the University of Massachusetts ("UMass") for rights to its miniCEP290 program (the "miniCEP290 License Agreement"). Pursuant to the terms of the miniCEP290 License Agreement, the Company issued to UMass 75,000 shares of the Company's common stock, which were valued at approximately $0.1 million. Based on and relying on certain representations made by UMass, the Company issued those shares pursuant to an exemption from registration afforded by Section 4(a)(2) of the Securities Act.
4. Net Income (Loss) Per Common Share
Basic and diluted net loss per common share is determined by dividing net loss by the weighted average common shares and pre-funded warrants outstanding during the period. Basic and diluted shares outstanding includes the weighted average effect of the Company's outstanding pre-funded warrants as the exercise of such pre-funded warrants requires nominal consideration to be given for the delivery of the corresponding shares of common stock. As of December 31, 2020 and 2019, the Company had 3,164,280 and 3,750,000 pre-funded warrants outstanding, respectively, which if exercised, would increase the number of shares of common stock issued and outstanding. For the periods when there is a net loss, shares underlying stock options and RSUs have been excluded from the calculation of diluted net loss per common share because the effect of including such shares would be anti-dilutive. Therefore, the weighted average common shares used to calculate both basic and diluted net loss per common share would be the same.

5. Cash, Cash Equivalents and Available for Sale Securities
The Company considers all highly liquid investments purchased with original maturities of 90 days or less at the date of purchase to be cash equivalents. As of December 31, 2020 and December 31, 2019 the Company had cash and cash equivalents of approximately $66.4 million and $125.7 million, respectively. Cash and cash equivalents at December 31, 2020 and December 31, 2019 included cash of $8.4 million and $3.2 million, respectively. As of December 31, 2020 and December 31, 2019, cash and cash equivalents also included $58.0 million and $122.5 million, respectively, of investments in money market funds and certain short-term investment-grade corporate debt securities with original maturities of 90 days or less.
The Company considers securities with original maturities of greater than 90 days at the date of purchase to be available for sale securities. The Company had available for sale securities of approximately $143.7 million at December 31, 2020. The available for sale securities listed at December 31, 2020 mature in one year or less. The Company held no available for sale securities at December 31, 2019.
The Company evaluates securities with unrealized losses, if any, to determine whether the decline in fair value has resulted from credit loss or other factors. The Company has determined that there were no credit losses in fair value of its investments as of December 31, 2020. Factors considered in determining whether a loss resulted from a credit loss or other factors included the length of time and extent to which the investment’s fair value has been less than the cost basis, the financial condition and near-term prospects of the investee, the extent of the loss related to credit of the issuer, the expected cash flows from the security, the Company’s intent to sell the security, and whether or not the Company will be required to sell the security before the recovery of its amortized cost.
The Company classifies these securities as available for sale. However, the Company has not sold and does not currently intend to sell its investments and the Company believes it is more likely than not that the Company will recover the carrying value of these investments.

6. Fair Value Measurements
ASC 820, Fair Value Measurements and Disclosures, defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The fair value standard also establishes a three-level hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.
The Company reviews investments on a periodic basis for other than temporary impairments. This review is subjective as it requires management to evaluate whether an event or change in circumstances has occurred in the period that may have a significant adverse effect on the fair value of the investment. The Company uses the market approach to measure fair value for its financial assets. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets. The Company classifies its investment-grade corporate debt securities within the fair value hierarchy as Level 2 assets, as it primarily utilizes quoted market prices or rates for similar instruments to value these securities.
The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels are defined as follows:
•Level 1—inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market. The Company's Level 1 assets consist of investments in money market funds and U.S. Treasury securities.
•Level 2—inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability. The Company's Level 2 assets may consist of investments in investment-grade corporate debt securities.
•Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability. The Company does not hold any assets that are measured using Level 3 inputs.

7. Inception 4 Acquisition
In October 2018, the Company entered into an Agreement and Plan of Merger (the “Inception 4 Merger Agreement”) by and among the Company, Orion Ophthalmology Merger Sub, Inc., a Delaware corporation and a direct, wholly owned subsidiary of the Company (“Merger Sub I”), Orion Ophthalmology LLC, a Delaware limited liability company and a direct, wholly owned subsidiary of the Company (“Orion”), Inception 4, Inc., a Delaware corporation ("Inception 4"), and, solely in its capacity as the representative, agent and attorney-in-fact of the equityholders of Inception 4, Fortis Advisors LLC, a Delaware limited liability company. Pursuant to the Inception 4 Merger Agreement, in October 2018, the Company acquired Inception 4 through the merger of Merger Sub I with and into Inception 4, with Inception 4 surviving as a direct, wholly owned subsidiary of the Company, and as part of the same overall transaction, the merger of Inception 4 with and into Orion, with Orion surviving as a direct, wholly owned subsidiary of the Company (the transactions are collectively referred to as the "Inception 4 Merger"). Prior to the Inception 4 Merger, Inception 4 was a privately held biotechnology company focused on the research and development of small molecule HtrA1 inhibitors for age-related retinal diseases in humans.
Pursuant to the terms of the Inception 4 Merger Agreement, as upfront consideration, the Company issued approximately 5.2 million shares of the Company’s common stock to the former equityholders of Inception 4, which were valued at approximately $11.7 million based on the closing price of the Company’s common stock on the acquisition date equal

7. Inception 4 Acquisition (Continued)
to $2.26 per share. Additionally, subject to the terms and conditions of the Inception 4 Merger Agreement, the former equityholders of Inception 4 will be entitled to receive contingent payments up to an aggregate of $105.0 million from the Company for the achievement of specified clinical and regulatory milestones, with $45 million of such potential payments relating to GA and $60 million of such potential payments relating to wet AMD. The future milestone payments will be payable in the form of shares of the Company's common stock, calculated based on the price of its common stock over a five-trading day period preceding the achievement of the relevant milestone, unless and until the issuance of such shares would, together with all other shares issued in connection with the Inception 4 Merger, exceed an overall maximum limit of approximately 7.2 million shares, which is equal to 19.9% of the number of issued and outstanding shares of the Company's common stock as of the close of business on the business day prior to the closing date of the Inception 4 Merger, and will be payable in cash thereafter.
At closing, the Company acquired all of Inception 4's assets, which included intellectual property and in-process research and development (“IPR&D”) associated with Inception 4’s HtrA1 inhibitor program and approximately $6.1 million in cash. There were no other tangible assets, leases or liabilities.
The Company evaluated the acquisition of Inception 4 under ASU No. 2017-01, Business Combinations: Clarifying the Definition of a Business. Based on the results of the analysis performed, the Company concluded that substantially all of the fair value of the gross assets acquired under the Inception 4 Merger Agreement is concentrated in a single identifiable asset. As a result, the Company concluded that the acquisition of Inception 4 does not represent an acquisition of a business and does not qualify as a business combination to be accounted for under ASC 805. Further, the Company concluded that the legal entity is not a variable interest entity under ASC 810 - Consolidation. Consequently, the Company concluded that the acquisition of Inception 4 should be accounted for as an asset acquisition under ASC 805-50. As the contingent consideration is not a derivative under ASC 815 - Derivatives and Hedging, any contingent payments will be recognized when earned or achieved and such amounts will be expensed upon payment for pre-commercial activities and capitalized for regulatory approvals and post-commercial activities. Further, as the acquired IPR&D has no alternative future use, in accordance with ASC 730, at closing, the Company charged to expense its allocated fair value of $6.9 million, which is the total acquisition consideration including transaction costs of $1.3 million less the cash acquired.
8. Licensing and Commercialization Agreements
Zimura License Agreement with Archemix Corp.
In September 2011, the Company entered into an amended and restated exclusive license agreement with Archemix Corp. ("Archemix") relating to anti-C5 aptamers (as amended, the "C5 License Agreement"). The C5 License Agreement superseded a July 2007 agreement between the Company and Archemix. Under the C5 License Agreement, the Company holds exclusive worldwide licenses, subject to certain pre–existing rights, under specified patents and technology owned or controlled by Archemix to develop, make, use, sell, offer for sale, distribute for sale, import and export pharmaceutical products comprised of or derived from an anti-C5 aptamer, including Zimura, for the prevention, treatment, cure or control of human indications, diseases, disorders or conditions of the eye, adnexa of the eye, orbit and optic nerve, other than certain expressly excluded applications.
In connection with the C5 License Agreement, the Company paid Archemix an upfront licensing fee of $1.0 million and issued to Archemix an aggregate of 2,000,000 shares of its series A-1 preferred stock and 500,000 shares of its series B-1 preferred stock. The Company has paid Archemix an aggregate of $9.0 million in fees based on its achievement of specified clinical milestone events under the C5 License Agreement, including two milestone payments of $1.0 million and $6.0 million, respectively, triggered by the positive 12-month data from, and by completion of, the GATHER1 trial, which the Company paid in March 2020 and October 2020, respectively.
Under the C5 License Agreement, for each anti-C5 aptamer product that the Company may develop under the agreement, including Zimura, it is obligated to make additional payments to Archemix of up to an aggregate of $50.5 million if it achieves specified development, clinical and regulatory milestones, with $24.5 million of such payments relating to a first indication, $23.5 million of such payments relating to second and third indications and $2.5 million of such payments relating to sustained delivery applications. Under the C5 License Agreement, it is also obligated to make additional payments to

8. Licensing and Commercialization Agreements (Continued)
Archemix of up to an aggregate of $22.5 million if it achieves specified commercial milestones based on net product sales of all anti-C5 products licensed under the agreement. It is also obligated to pay Archemix a double-digit percentage of specified non-royalty payments it may receive from any sublicensee of its rights under the C5 License Agreement. The Company is not obligated to pay Archemix a running royalty based on net product sales in connection with the C5 License Agreement.
Unless earlier terminated, the C5 License Agreement will expire upon the latest of 12 years after the first commercial sale in any country of the last licensed product, the expiration of the last-to-expire valid claim of the licensed patents that covers a licensed product, and the date on which no further payments of sublicensing income are to be received by the Company.
Either the Company or Archemix may terminate the C5 License Agreement if the other party materially breaches the agreement and the breach remains uncured for a specified period. Archemix may also terminate the C5 License Agreement, or may convert the Company's exclusive license under the agreement to a non-exclusive license, if the Company challenges or assists a third party in challenging the validity or enforceability of any of the patents licensed under the agreement. The Company may terminate the agreement at any time and for any or no reason effective at the end of a specified period following its written notice of termination to Archemix.
IC-100 Agreements with the University of Florida Research Foundation and the University of Pennsylvania
In June 2018, the Company entered into an exclusive global license agreement (the "RHO-adRP License Agreement") with the University of Florida Research Foundation, Incorporated ("UFRF") and the University of Pennsylvania ("Penn" and collectively with UFRF, the "Licensors"). Under the agreement, the Licensors granted the Company a worldwide, exclusive license under specified patent rights and a worldwide, non-exclusive license under specified know-how, including specified preclinical data, to manufacture, develop and commercialize certain AAV gene therapy products for the treatment of rhodopsin-mediated diseases. The rights granted under the RHO-adRP License Agreement included certain patent rights covering IC-100, the Company's novel AAV gene therapy product candidate intended to treat RHO-adRP.
In June 2018, the Company paid UFRF, on behalf of both Licensors, a $0.5 million upfront license issuance fee in connection with entry into the agreement, which was recorded as a research and development expense, as well as accrued patent prosecution expenses of approximately $30 thousand, which was recorded as a general and administrative expense. Under the agreement, the Company agreed to pay an annual license maintenance fee in the low double-digit thousands of dollars, which will be payable on an annual basis until the first commercial sale of a licensed product. In addition, the Company agreed to reimburse UFRF for the costs and expenses of patent prosecution and maintenance related to the licensed patent rights.
The Company further agreed to pay UFRF, on behalf of both Licensors, up to an aggregate of $23.5 million if the Company achieves specified clinical, marketing approval and reimbursement approval milestones with respect to a licensed product and additionally, up to an aggregate of $70.0 million if the Company achieves specified commercial sales milestones with respect to a licensed product.
The Company is also obligated to pay UFRF, on behalf of both Licensors, royalties at a low single-digit percentage of net sales of licensed products. Such royalties are subject to customary reductions for lack of patent coverage and loss of regulatory exclusivity. In addition, such royalties with respect to any licensed product in any country may be offset by a specified portion of any royalty payments actually paid by the Company in such country under third-party licenses for patent rights or other intellectual property rights that are necessary to manufacture, develop and commercialize the licensed product in such country. The Company's obligation to pay royalties under the RHO-adRP License Agreement will continue on a licensed product-by-licensed product and country-by-country basis until the latest of:
•the expiration of the last-to-expire licensed patent rights covering a licensed product in the country of sale;
•the expiration of regulatory exclusivity covering a licensed product in the country of sale; and
•ten years from the first commercial sale of the applicable licensed product in the country of sale.
Beginning on the earlier of (i) the calendar year following the first commercial sale of a licensed product and (ii) the first business day of 2031, the Company is also obligated to pay certain minimum royalties, not to exceed an amount in the low

hundreds of thousands of dollars on an annual basis, which minimum royalties are creditable against the Company's royalty obligation with respect to net sales of licensed products due for the year in which the minimum royalty is paid.
In addition, if the Company or an affiliate sublicenses any of the licensed patent rights to a third party, the Company will be obligated to pay UFRF, on behalf of both Licensors, a low double-digit percentage of the consideration received in exchange for such sublicense. If the Company receives a rare pediatric disease priority review voucher from the FDA in connection with obtaining marketing approval for a licensed product and the Company subsequently uses such priority review voucher in connection with a different product candidate, the Company will be obligated to pay UFRF, on behalf of both Licensors, aggregate payments in the low double-digit millions of dollars based on certain marketing approval and commercial sales milestones with respect to such other product candidate. If the Company sells such priority review voucher to a third party, it will be obligated to pay UFRF, on behalf of both licensors, a low double-digit percentage of any consideration received from such third party in connection with such sale.
Unless earlier terminated by the Company, the RHO-adRP License Agreement will expire upon the expiration of the Company’s obligation to pay royalties to UFRF on net sales of licensed products. The Company may terminate the agreement at any time for any reason upon prior written notice to UFRF. Penn or UFRF may terminate the RHO-adRP License Agreement in the event of certain breaches by the Company or in the event of certain insolvency events regarding the Company.
In addition to the exclusive license agreement, the Company and Penn also entered into to a Master-Sponsored Research Agreement (the "RHO-adRP MSRA"), facilitated by the Penn Center for Innovation. Under the RHO-adRP MSRA, the Company and Penn conducted several preclinical studies of IC-100, as well as a natural history study of RHO-adRP patients. The total amount of funding for the sponsored research covered by statements of work under the RHO-adRP MSRA that the Company has committed to date and is expecting to commit to is in the low single-digit millions of dollars.
IC-200 Agreements with University of Pennsylvania and University of Florida Research Foundation
In April 2019, the Company entered into an exclusive global license agreement (the "BEST1 License Agreement") with Penn and UFRF. The Company entered into the BEST1 License Agreement by exercising its exclusive option rights under an option agreement that it previously entered into with Penn and UFRF in October 2018. Under the BEST1 License Agreement, Penn and UFRF granted the Company a worldwide, exclusive license under specified patent rights and specified know-how and a worldwide, non-exclusive license under other specified know-how to research, develop, manufacture and commercialize certain AAV gene therapy products, including IC-200, for the treatment of Best disease and other BEST1-related IRDs.
In May 2019, the Company paid Penn, for the benefit of the Licensors, a $0.2 million upfront license issuance fee, which was recorded as a research and development expense, and the Company paid UFRF accrued patent prosecution expenses of approximately $18 thousand, which was recorded as a general and administrative expense. The Company has also agreed to pay Penn, for the benefit of the Licensors, an annual license maintenance fee in the low double-digit thousands of dollars, which will be payable on an annual basis until the first commercial sale of a licensed product. In addition, the Company have agreed to pay Penn, for the benefit of the Licensors, a one-time patent grant fee in the low triple-digit thousands of dollars, upon the issuance of a U.S. patent that claims inventions disclosed in the licensed patent rights or know-how or inventions generated under certain related sponsored research agreements with Penn or UFRF, and that is exclusively licensed to the Company. Furthermore, it has agreed to reimburse Penn and UFRF for the costs and expenses of patent prosecution and maintenance related to the licensed patent rights.
The Company has further agreed to pay Penn, for the benefit of the Licensors, up to an aggregate of $15.7 million if it achieves specified clinical, marketing approval and reimbursement approval milestones with respect to one licensed product, and up to an aggregate of an additional $3.1 million if it achieves these same milestones with respect to a different licensed product. In addition, it has agreed to pay Penn, for the benefit of the Licensors, up to an aggregate of $48.0 million if it achieves specified commercial sales milestones with respect to one licensed product, and up to an aggregate of an additional $9.6 million if it achieves these same milestones with respect to a different licensed product.

8. Licensing and Commercialization Agreements (Continued)
The Company is also obligated to pay Penn, for the benefit of the Licensors, royalties at a low single-digit percentage of net sales of licensed products. Such royalties are subject to customary deductions, credits, and reductions for lack of patent coverage and loss of regulatory exclusivity. In addition, such royalties with respect to any licensed product in any country may be offset by a specified portion of any royalty payments actually paid by the Company in such country under third-party licenses to patent rights or other intellectual property rights that are necessary to research, develop, manufacture and commercialize the licensed product in such country. Its obligation to pay royalties under the BEST1 License Agreement will continue on a licensed product-by-licensed product and country-by-country basis until the latest of:
•the expiration of the last-to-expire licensed patent rights covering the sale of the applicable licensed product in the country of sale;
•the expiration of regulatory exclusivity covering the applicable licensed product in the country of sale; and
•10 years from the first commercial sale of the applicable licensed product in the country of sale.
Beginning on the earlier of the calendar year following the first commercial sale of a licensed product and calendar year 2032, the Company is also obligated to pay certain minimum royalties, not to exceed an amount in the mid tens of thousands of dollars on an annual basis, which minimum royalties are creditable against its royalty obligation with respect to net sales of licensed products due in the year the minimum royalty is paid.
If the Company or any of its affiliates sublicense any of the licensed patent rights to a third party, it will be obligated to pay Penn, for the benefit of the Licensors, a high single-digit to a mid ten's percentage of the consideration received in exchange for such sublicense, with the applicable percentage based upon the stage of development of the sublicensed product at the time it or the applicable affiliate enters into the sublicense.
If the Company receives a rare pediatric disease priority review voucher from the FDA in connection with obtaining marketing approval for a licensed product and the Company subsequently uses such priority review voucher in connection with a different product candidate outside the scope of the BEST1 License Agreement, it will be obligated to pay Penn, for the benefit of the Licensors, aggregate payments in the low double-digit millions of dollars based on certain approval and commercial sales milestones with respect to such other product candidate. In addition, if it sells such a priority review voucher to a third party, it will be obligated to pay Penn, for the benefit of the Licensors, a high single-digit percentage of any consideration received from such third party in connection with such sale.
The BEST1 License Agreement, unless earlier terminated by the Company or Penn or UFRF, will expire upon the expiration of the Company's obligation to pay royalties on net sales of licensed products. Before the effectiveness of an IND for a licensed product, the Company may terminate the BEST1 License Agreement with respect to such licensed product or in its entirety, at any time for any reason upon prior written notice to Penn and UFRF. Following the effectiveness of an IND for a licensed product, it may terminate the BEST1 License Agreement with respect to such licensed product by providing Penn prior written notice and a certification that it is ceasing all use, research and development and commercialization of such licensed product, subject to certain limited exceptions. It may also terminate the BEST1 License Agreement if Penn or UFRF materially breaches the BEST1 License Agreement and does not cure such breach within a specified cure period.
Penn or UFRF may terminate the BEST1 License Agreement if the Company materially breaches the BEST1 License Agreement and does not cure such breach within a specified cure period, if it experiences a specified insolvency event, if it ceases to carry on the entirety of its business related to the licensed patent rights, if it ceases for more than four consecutive quarters to make any payment of earned royalties on net sales of licensed products following the commencement of commercialization thereof, unless such cessation is based on safety concerns that the Company is actively attempting to address, or if it, any of its affiliates or any of its sublicensees challenges or assists a third party in challenging the validity, scope, patentability, and/or enforceability of the licensed patent rights. If it materially breaches certain diligence obligations under the BEST1 License Agreement with respect to only one licensed product, then Penn and UFRF may only terminate its rights and licenses under the BEST1 License Agreement for such licensed product, but not for other licensed products.
In addition to the exclusive license agreement, the Company and Penn also entered into a Master-Sponsored Research Agreement (the "BEST1 MSRA"), facilitated by the Penn Center for Innovation. Under the BEST1 MSRA, the Company and

License Agreement with University of Massachusetts for the miniCEP290 Program
In July 2019, the Company entered into the miniCEP290 License Agreement with UMass by exercising its exclusive option rights under an option agreement and a sponsored research agreement that it previously entered into with UMass in February 2018. Under the miniCEP290 License Agreement, UMass granted it a worldwide, exclusive license under specified patent rights and specified biological materials and a non-exclusive license under specified know-how to make, have made, use, offer to sell, sell, have sold and import products for the treatment of diseases associated with mutations in the CEP290 gene, including LCA10.
In July 2019, the Company issued to UMass 75,000 shares of its common stock following execution of the miniCEP290 License Agreement pursuant to an exemption from registration afforded by Section 4(a)(2) of the Securities Act. In September 2019, it paid UMass a $0.4 million upfront license fee, which was recorded as a research and development expense, and it paid UMass accrued patent prosecution expenses of approximately $18 thousand, which was recorded as a general and administrative expense.
The Company has also agreed to pay UMass an annual license maintenance fee in the low double-digit thousands of dollars, which will be payable on an annual basis until the expiration of the royalty term for the licensed products. Furthermore, it has agreed to reimburse UMass for the costs and expenses of patent prosecution and maintenance related to the licensed patent rights.
The Company has further agreed to pay UMass up to an aggregate of $14.75 million in cash and issue up to 75,000 shares of its common stock if it achieves specified clinical and regulatory milestones with respect to a licensed product. In addition, the Company has agreed to pay UMass up to an aggregate of $48.0 million if it achieves specified commercial sales milestones with respect to a licensed product.
The Company is also obligated to pay UMass royalties at a low single-digit percentage of net sales of licensed products. Its obligation to pay royalties under the miniCEP290 License Agreement will continue on a licensed product-by-licensed product and country-by-country basis until the later of: (a) the expiration of the last-to-expire licensed patent rights covering the sale of the applicable licensed product in the country of sale, or (b) 10 years from the first commercial sale of the applicable licensed product in the country of sale. Beginning with the calendar year following receipt of marketing approval for a licensed product, it is also obligated to pay certain minimum royalties, not to exceed an amount in the mid-double-digit thousands of dollars on an annual basis, which minimum royalties are creditable against its royalty obligation with respect to net sales of licensed products due in the year the minimum royalty is paid.
If the Company or any of its affiliates sublicenses any of the licensed patent rights or know-how to a third party, it will be obligated to pay UMass a high single-digit to a mid-tens percentage of the consideration received in exchange for such sublicense, with the applicable percentage based upon the stage of development of the licensed products at the time it or the applicable affiliate enters into the sublicense.
If the Company receives a rare pediatric disease priority review voucher from the FDA in connection with obtaining marketing approval for a licensed product, and it subsequently uses such priority review voucher in connection with a different product candidate outside the scope of the miniCEP290 License Agreement, it will be obligated to pay UMass a low-tens percentage of the fair market value of the priority review voucher at the time of approval of such product candidate and a low-twenties percentage of the fair market value of the priority review voucher at the time of achievement of a specified commercial sales milestone for such other product candidate. In addition, if it sells such a priority review voucher to a third party, it will be obligated to pay UMass a low-thirties percentage of any consideration received from such third party in connection with such sale.

9. Financing Agreement with Novo Holdings A/S
In May 2013, the Company entered into a Purchase and Sale Agreement (the "Novo Agreement") with Novo Holdings A/S ("Novo" and formerly Novo A/S), pursuant to which the Company obtained financing in three tranches in an aggregate amount equal to $125.0 million in return for the sale to Novo of aggregate royalties of a mid-single digit percentage on worldwide sales of (a) Fovista, (b) certain Fovista-related Products ("Fovista-Related Products"), and (c) certain other antagonists of platelet-derived growth factor ("PDGF"), if any, that the Company initiated development activities for prior to the fifth anniversary of the Novo Agreement (collectively, the "Anti-PDGF Royalty Products"). The Company received the cash payments from Novo in each of May 2013, January 2014 and November 2014. the Company received cash payments of $41.7 million, or $125.0 million in the aggregate.
The $125.0 million in aggregate proceeds from the three financing tranches under the Novo Agreement represented the full funding available under the Novo Agreement, and prior to December 31, 2018, was recorded as a royalty purchase liability on the Company's Balance Sheet, in accordance with ASC 730, Research and Development. Because there was a significant related party relationship between the Company and Novo, the Company treated its obligation to make royalty payments under the Novo Agreement as an implicit obligation to repay the funds advanced by Novo.
On December 31, 2018, the Company and Novo entered into a letter agreement (the "Novo Termination Agreement"), that terminated the Novo Agreement. As a result of the Novo Termination Agreement, Novo relinquished all rights to receive royalties based on net sales of Anti-PDGF Royalty Products. In exchange, the Company agreed to forbear from any future filing, prosecution, maintenance or enforcement of any intellectual property rights related to Anti-PDGF Royalty Products, and from granting any third party any right or license in any such intellectual property rights or clinical study data generated by or on behalf of the Company, its affiliates, licensees or sublicensees, for the development, manufacture or commercialization of Anti-PDGF Royalty Products or any other antagonists of PDGF. The foregoing restriction does not apply to gene therapies (so long as the Company does not grant any rights or licenses to intellectual property or clinical study data related to Fovista or Fovista-Related Products). The Company further agreed, until December 31, 2028, not to develop, manufacture, seek or obtain regulatory approval for, or commercialize any Anti-PDGF Royalty Products without the prior written consent of Novo. The foregoing restriction does not apply to any gene therapies (so long as the Company does not utilize data related to Fovista or Fovista-Related Products).
As a result of the Novo Termination Agreement, the Company has no obligation to repay Novo the $125.0 million through future product royalties or any other development activities. Accordingly, the Company extinguished the $125.0 million royalty purchase liability from its Consolidated Balance Sheet at December 31, 2018 and recognized a related gain of $125.0 million in its Consolidated Statements of Operations for the year ended December 31, 2018. The extinguishment of the royalty purchase liability and the related gain did not impact the Company's cash balance during that period, as the Company had received the proceeds related to the royalty purchase liability in prior periods.

11. Income Taxes
The Company utilizes the liability method of accounting for deferred income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. A valuation allowance is established against deferred tax assets when, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company's policy is to record interest and penalties on uncertain tax positions as income tax expense.
Deferred income taxes reflect the net effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A reconciliation of the statutory U.S. federal rate to the Company's effective tax rate is as follows:

The Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of taxable income during the periods in which the temporary differences representing net future deductible amounts become deductible.
The Company incurred tax losses in 2020 and 2019. The Company has carried forward its federal and state tax losses due to the inability of carryback claims. Federal NOLs incurred prior to 2018 will begin to expire in 2034 if not utilized. Post 2017 Federal NOLs have an unlimited life. The state NOLs are expected to begin to expire in 2028. Due to the Company's history of losses and lack of other positive evidence to support taxable income, the Company has recorded a valuation allowance against those remaining deferred tax assets that are not expected to be realized. As of December 31, 2020, the Company has federal NOL carryforwards of approximately $445.0 million.
For the year ended December 31, 2020, the Company recorded a benefit from income taxes of $3.7 million to reflect the settlement of a local tax audit and the associated decrease in the Company's related uncertain tax position, including interest and penalties. For the years ended December 31, 2019 and 2018, the Company recorded an income tax benefit of $0.1 million and $1.1 million, respectively, due primarily to reflect the settlements of local tax audits. During 2019, the Company received $1.8 million related to the refund of the aforementioned AMT credits and recorded a tax receivable of $1.8 million to reflect the

refund of AMT credits it expects to receive over the next three years. On March 27, 2020, in response to the COVID-19 pandemic, the U.S. Congress enacted the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"). The CARES Act provides numerous tax provisions and other stimulus measures, including the immediate refund of minimum tax credits. The Company has recorded a current tax receivable of approximately $1.8 million in anticipation of this refund. During 2020, the Company applied for a refund of the remaining AMT credits of $1.8 million and anticipates receiving this refund in 2021.
The Company generated net income before income taxes for the year ended December 31, 2018. This income was due to the Novo Termination Agreement. With respect to the remaining deferred tax assets, except for the AMT credits previously discussed above, there was no change in the amount of assets realizable at December 31, 2020.
Pursuant to ASC 740, Income Taxes, the Company routinely evaluates the likelihood of success if challenged on income tax positions claimed on its income tax returns. During the year ended December 31, 2020, the Company reduced its uncertain tax liability by approximately $5.2 million following the settlement of state tax audits. The Company increased certain deferred tax assets by $0.3 million and increased the corresponding valuation allowance by an equivalent amount.
The Company's position with respect to uncertain tax positions is set forth below:
| Opening balance | $ | 12,227 | |||
| Gross amount of increases in unrecognized tax benefits during the period - current year provisions | — | ||||
| Gross amount of increases in unrecognized tax benefits during the period - prior year provisions | — | ||||
| Gross amount of decreases in unrecognized tax benefits during the period - other | (659) | ||||
| Decreases due to settlement with tax authorities during the period | (4,845) | ||||
| Reduction of unrecognized tax benefits due to expiration of the state of limitations during the period | — | ||||
| Closing Balance | $ | 6,723 | |||
The Company will continue to evaluate its ability to realize its deferred tax assets on a periodic basis and will adjust such amounts in light of changing facts and circumstances including, but not limited to, future projections of taxable income, tax legislation, rulings by relevant tax authorities, the progress of ongoing tax audits and the regulatory approval of product candidates currently under development. Any additional changes to the valuation allowance recorded on deferred tax assets in the future would impact the Company’s income taxes.
12. Operating Leases
The Company's principal executive offices was previously at One Penn Plaza, New York, NY. The term of this lease expired in December 2020.
Effective December 1, 2020, the Company changed the location of its principal executive offices to Five Penn Plaza, New York, NY.

The Company will recognize a right-to-use asset and lease liability when the term of the lease commences, which is expected to be in early 2021. The term of the lease for the Company's Parsippany office will expire in August 2023.
For the years ended December 31, 2020, 2019 and 2018, lease and rent expense was $0.6 million, $1.0 million, and $0.8 million, respectively. Cash paid from operating cash flows for amounts included in the measurement of lease liabilities was $0.6 million and $1.0 million for the years ended December 31, 2020 and 2019, respectively. At December 31, 2020, the Company's operating leases had a weighted average remaining lease term of 2.1 years and a weighted average estimated incremental borrowing rate of 3.4% .

Legal Proceedings
On January 11, 2017, a putative class action lawsuit was filed against the Company and certain of its current and former executive officers in the United States District Court for the Southern District of New York, captioned Frank Micholle v. IVERIC bio, Inc., et al., No. 1:17-cv-00210. On March 9, 2017, a related putative class action lawsuit was filed against the Company and the same group of its current and former executive officers in the United States District Court for the Southern District of New York, captioned Wasson v. IVERIC bio, Inc., et al., No. 1:17-cv-01758. These cases were consolidated on March 13, 2018. On June 4, 2018, the lead plaintiff filed a consolidated amended complaint (the “CAC”). The CAC purports to be brought on behalf of shareholders who purchased the Company’s common stock between March 2, 2015 and December 12, 2016. The CAC generally alleges that the Company and certain of its officers violated Sections 10(b) and/or 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder by making allegedly false and/or misleading statements concerning the results of the Company’s Phase 2b trial and the prospects of the Company’s Phase 3 trials for Fovista in combination with anti-VEGF agents for the treatment of wet AMD. The CAC seeks unspecified damages, attorneys’ fees, and other costs. The Company and individual defendants filed a motion to dismiss the CAC on July 27, 2018. On September 18, 2019, the court issued an order dismissing some, but not all, of the allegations in the CAC. On November 18, 2019, the Company and the individual defendants filed an answer to the complaint. On June 12, 2020, the lead plaintiff filed a motion for class certification. On August 11, 2020, the defendants filed a notice of non-opposition to lead plaintiff's motion for class certification. This case is currently in the discovery phase.
On February 7, 2018, a shareholder derivative action was filed against the members of the Company’s Board of Directors in the New York Supreme Court Commercial Division, captioned Cano v. Guyer, et al., No. 650601/2018. The complaint alleges that the defendants breached their fiduciary duties to the Company by adopting a compensation plan that overcompensates the non-employee members of the Board relative to boards of companies of comparable market capitalization and size. The complaint also alleges that the defendants were unjustly enriched as a result of the alleged conduct. The complaint purports to seek unspecified damages, on behalf of the Company, attorneys’ fees, and other costs, as well as an order directing the Company to reform and improve its corporate governance and internal procedures to comply with applicable laws. The Company filed a motion to dismiss this case on May 14, 2018. On June 4, 2018, the plaintiff filed an amended complaint. On June 25, 2018, the Company filed a renewed motion to dismiss this case. On December 3, 2018, the parties filed a stipulation of settlement that contemplates that the Company will adopt certain compensation-related governance reforms and does not obligate the defendants or the Company to pay any monetary damages. The court approved the settlement at a hearing on March 12, 2019. As part of the settlement, in April 2019 the Company paid $0.3 million in fees and costs to plaintiff's counsel. As contemplated by the settlement, the Company's board of directors adopted certain compensation-related governance reforms, including a non-employee director compensation policy, which its stockholders approved on May 15, 2019 at its 2019 annual meeting.
On August 31, 2018, a shareholder derivative action was filed against current and former members of the Company's Board of Directors and certain current and former officers of the Company in the United States District Court for the Southern District of New York, captioned Luis Pacheco v. David R. Guyer, et al., Case No. 1:18-cv-07999. The complaint, which is based substantially on the facts alleged in the CAC, alleges that the defendants breached their fiduciary duties to the Company and wasted the Company's corporate assets by failing to oversee the Company's business, and also alleges that the defendants

were unjustly enriched as a result of the alleged conduct, including through receipt of bonuses, stock options and similar compensation from the Company, and through sales of the Company's stock between March 2, 2015 and December 12, 2016. The complaint purports to seek unspecified damages on the Company's behalf, attorneys’ fees, and other costs, as well as an order directing the Company to reform and improve its corporate governance and internal procedures to comply with applicable laws, including submitting certain proposed amendments to the Company's corporate charter, bylaws and corporate governance policies for vote by the Company's stockholders. On December 14, 2018, the Company filed a motion to dismiss the complaint. On September 19, 2019, the court denied its motion to dismiss this complaint. This matter was subsequently referred to a special litigation committee of the Company's board of directors. On February 18, 2020, the Company filed an answer to the complaint. The Company and the plaintiff agreed to stay this litigation while the special litigation committee conducts its investigation. On May 4, 2020, the court approved the stipulation and stayed the litigation through November 1, 2020. By agreement of the parties, the court has since extended the stay through March 13, 2021. The Company also entered into tolling agreements with the defendant directors to December 2021.
On October 16, 2018, the Company’s board of directors received a shareholder demand to investigate and commence legal proceedings against certain members of the Company’s board of directors. The demand alleges facts that are substantially similar to the facts alleged in the CAC and the Pacheco complaint and asserts claims that are substantially similar to the claims asserted in the Pacheco complaint. On January 30, 2019, the Company’s board of directors received a second shareholder demand from a different shareholder to investigate and commence legal proceedings against certain current and former members of the Company’s board of directors based on allegations that are substantially similar to the allegations contained in the first demand letter. These shareholder demands have been referred to a demand review committee of the Company's board of directors. The Company has entered into tolling agreements with the directors named in the demands to December 2021.
The Company denies any and all allegations of wrongdoing and intends to vigorously defend against these lawsuits. The Company is unable, however, to predict the outcome of these matters at this time. Moreover, any conclusion of these matters in a manner adverse to the Company and for which it incurs substantial costs or damages not covered by the Company's directors’ and officers’ liability insurance would have a material adverse effect on its financial condition and business. In addition, the litigation could adversely impact the Company's reputation and divert management’s attention and resources from other priorities, including the execution of its business plan and strategies that are important to the Company's ability to grow its business, any of which could have a material adverse effect on the Company's business.
14. Stock-Based Compensation and Compensation Plans
The Company adopted its 2007 Stock Incentive Plan (the "2007 Plan") for employees, non-employee directors and consultants for the purpose of advancing the interests of the Company's stockholders by enhancing its ability to attract, retain and motivate persons who are expected to make important contributions to the Company. The 2007 Plan provided for the granting of stock option awards, RSUs, and other stock-based and cash-based awards. Following the effectiveness of the 2013 Stock Incentive Plan described below in connection with the closing of the Company's initial public offering, the Company is no longer granting additional awards under the 2007 Plan.
In August 2013, the Company's board of directors adopted, and the Company's stockholders approved, the 2013 Stock Incentive Plan (the "2013 Plan"), which became effective immediately prior to the closing of the Company's initial public offering. In June 2015, the Company’s board of directors adopted a first amendment to the 2013 Plan. The 2013 Plan provides for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, RSUs, restricted stock awards and other stock-based awards. Upon the effectiveness of the 2013 Plan, the number of shares of the Company's common stock that were reserved for issuance under the 2013 Plan was the sum of (1) a number of shares (up to a maximum of approximately 3,359,641 shares) that is equal to the sum of 739,317 shares (the number of shares of the Company's common stock then available for issuance under the 2007 Plan), and such number of shares of the Company's common stock that are subject to outstanding awards under the 2007 Plan that expire, terminate or are otherwise surrendered, canceled, forfeited or repurchased by the Company at their original issuance price pursuant to a contractual repurchase right, plus (2) an annual increase, to be added the first business day of each fiscal year, beginning with the fiscal year ending December 31, 2014 and continuing until, and including, the fiscal year ending December 31, 2023, equal to the lowest of 2,542,372 shares of the Company's common stock, 4% of the number of shares of the Company's common stock outstanding on the first day of the fiscal year and an amount

determined by its board of directors. The Company's employees, officers, directors, consultants and advisors are eligible to receive awards under the 2013 Plan. However, incentive stock options may only be granted to employees of the Company.
Annual increases under the evergreen provisions of the 2013 Plan have resulted in the addition of an aggregate of approximately 13,081,000 additional shares to the 2013 Plan, including for 2021, an increase of approximately 2,542,000 shares. As of December 31, 2020, the Company had approximately 421,000 shares available for grant under the 2013 Plan.
In October 2019, the Company's board of directors adopted the 2019 Inducement Stock Incentive Plan (the “2019 Inducement Plan”) to reserve 1,000,000 shares of its common stock to be used exclusively for grants of awards to individuals that were not previously employees or directors of the Company as a material inducement to such individuals’ entry into employment with the Company within the meaning of Rule 5635(c)(4) of the Nasdaq Listing Rules. In March 2020, the Company's board of directors amended the 2019 Inducement Plan to reserve an additional 1,000,000 shares of its common stock for issuance under the plan and in February 2021, the Company's board of directors further amended the 2019 Inducement Plan to reserve an additional 600,000 shares of its common stock for issuance under the plan. The terms and conditions of the 2019 Inducement Plan are substantially similar to those of the 2013 Plan. As of December 31, 2020, the Company had approximately 555,000 shares available for grant under the 2019 Inducement Plan.
In April 2016, the board of directors adopted the ESPP pursuant to which the Company may sell up to an aggregate of 1,000,000 shares of common stock. The ESPP was approved by the Company’s stockholders in June 2016. The ESPP allows eligible employees to purchase common stock at a price per share equal to 85% of the lower of the fair market value of the common stock at the beginning or end of each six month offering period during the term of the ESPP. The first offering period began in September 2016.
