Item 1. Business
Overview
We are a clinical-stage biopharmaceutical company focused on the discovery, development, and commercialization of novel small molecule therapeutics to address chronic and progressive fibrotic diseases. Our goal is to transform the treatment paradigm for patients suffering from these potentially life-threatening conditions for which there are no approved medicines or where existing approved medicines have known limitations. Our lead product candidate is ANG-3070, a highly selective oral tyrosine kinase receptor inhibitor (TKI) in development as a treatment for fibrotic diseases, particularly in the kidney and lung. ANG-3070 has demonstrated activity as an anti-fibrotic agent in a variety of animal models. A Phase 1 healthy volunteer study, which was designed to support clinical development in multiple indications, demonstrated ANG-3070 has a favorable safety and PK profile, producing plasma concentrations which exceeded the levels necessary for activity in animal models of proteinuric kidney diseases. Enrollment is ongoing in a dose-finding Phase 2 trial of ANG-3070 in primary proteinuric kidney diseases (PPKDs) and we expect to file an IND in idiopathic pulmonary fibrosis (IPF) by the end of 2022.
We continue to work with our license partner Vifor International, Ltd, (Vifor Pharma) on the process of closing out our analyses of data from the 2021 clinical trial readouts of ANG-3777, a hepatocyte growth factor (HGF) mimetic that was formerly our lead product candidate until December 2021. We do not intend to continue the clinical development plan for ANG-3777 set forth in the Vifor License, which had included a Phase 3 study for the prevention of AKI in patients undergoing cardiac surgery involving cardiopulmonary bypass who were thought to be at risk for AKI (CSA-AKI) and a Phase 4 confirmatory study in donor kidney transplant patients who were at risk for developing delayed graft function (DGF), given that we do not believe the earlier Phase 2 and Phase 3 clinical trial results in the respective indications support regulatory approval. We have no funds budgeted for additional clinical trials for ANG-3777.
We are also continuing to develop our preclinical programs. Our ROCK2 program is targeted towards the treatment of fibrotic diseases. Our CYP11B2 program is targeted towards diseases related to aldosterone synthase dysregulation.
ANG-3070 for Fibrotic Diseases.
Our lead product candidate is ANG-3070, a highly selective oral small molecule TKI we are developing as a potential treatment for fibrotic diseases. TKIs are one of the largest classes of newly approved drugs, with more than 25 approved molecules worldwide targeting pathways believed to affect relevant diseases. However, tyrosine kinases are ubiquitous proteins and there is significant overlap in their structures and binding sites. This can lead to binding against unintended tyrosine kinase targets and these off-target effects are largely responsible for the toxicity associated with TKIs. While no TKI can be entirely selective due to close structural homology of the various tyrosine kinases, ANG-3070 was designed with the intent of enhancing inhibition of kinases involved in inflammation and the progression of fibrosis while minimizing binding to kinases thought responsible for adverse or off-target effects. ANG-3070 demonstrated target engagement as an anti-fibrotic agent in a variety of animal models across different organ systems and has shown in vitro the ability to inhibit pro-fibrotic tyrosine kinases at exposures achievable by oral administration. We reported positive data from a Phase 1 healthy volunteer study in August of 2021 and are actively enrolling patients in JUNIPER, a randomized, multi-center, double-blind, and placebo-controlled global dose-finding Phase 2 trial to evaluate ANG-3070 in patients with primary proteinuric kidney diseases (PPKDs). We hold global rights to ANG-3070.
The potential advantages for ANG-3070 include:
•Significant Addressable Kidney Fibrosis Markets. The PPKDs of Focal Segmental Glomerular Sclerosis (FSGS), Immunoglobulin A Nephropathy (IgAN), Alport Syndrome, and Membranous Nephropathy (MN) together affect over 250,000 patients in the U.S. alone.
•Significant Addressable Pulmonary Fibrosis Markets. 2021 projected worldwide sales for the two approved drugs for IPF will be approximately $3.8 billion despite the fact that fewer than 30% of IPF patients in the U.S. are prescribed either drug and approximately half of IPF patients discontinue these therapies within 12 months.
•Promising Drug Exposure Profile. In the Phase 1 healthy volunteer study, ANG-3070 demonstrated ANG-3070 can achieve drug exposures exceeding plasma concentrations in which activity was demonstrated in animal models of proteinuric kidney diseases and pulmonary fibrosis. As such, ANG-3070 is being investigated for both twice-daily (BID) and once-daily (QD) dosing.
•Encouraging Adverse Event Profile. The safety and tolerability profile in the Phase 1 study was encouraging given the recognized incidence and severity of gastrointestinal side effects in approved kinase inhibitors, particularly nausea, vomiting, and diarrhea.
ANG-3070 for Renal Fibrosis. While PPKDs like FSGS, IgAN, MN, and Alport often have different root causes, each condition often progresses to kidney fibrosis and end-stage renal disease. There is only one approved therapy for any PPKD, budesonide for IgAN. In December 2021, we enrolled the first patient into JUNIPER, our randomized, double-blind, placebo-controlled global dose-finding Phase 2 trial intended to assess ANG-3070 in adult patients with FSGS or IgAN, two types of PPKD.
ANG-3070 for Pulmonary Fibrosis. Pulmonary fibrosis is characterized by progressive scarring (fibrosis) of the lungs, which leads to their deterioration and destruction. Over time, lung scarring in patients progresses and breathing becomes difficult, often resulting in the lungs failing to take in enough oxygen to meet the body’s needs. IPF is an aggressive form of lung disease with a median survival of two to three years from diagnosis. There are two drugs approved for IPF, the kinase inhibitor nintedanib (OFEV®) and the pyridine pirfenidone (Esbriet®). We plan to file an IND for ANG-3070 in the IPF indication by the end of 2022.
ANG-3777, an HGF Mimetic for Acute Organ Injury
ANG-3777 was designed to mimic the biological activity of HGF and to treat acute organ injuries, such as delayed graft function, where there are no approved therapies. HGF activates the c-Met receptor, which triggers a cascade of pathways with a central role in tissue repair and organ recovery that has been well established.
In the fourth quarter of 2021, we reported topline results from two clinical trials of ANG-3777. The first was a Phase 3 trial of ANG-3777 to treat AKI in patients who were at risk for developing DGF. The second was an exploratory Phase 2 trial for the prevention of CSA-AKI. While neither trial achieved statistical significance on its primary endpoint, we believe ANG-3777 demonstrated biologic activity in both trials. We continue to work with our license partner Vifor International, Ltd. (Vifor Pharma) on the process of closing out our analyses of data from these trials. We do not intend to continue the clinical development plan for ANG-3777 set forth in the Vifor License, which had included a Phase 3 study in CSA-AKI and a Phase 4 confirmatory study in DGF. There are no funds budgeted for additional clinical trials for ANG-3777.
In November 2020, we entered into a license agreement (the Vifor License) with Vifor Pharma, granting Vifor Pharma global rights (excluding Greater China) to develop, manufacture and commercialize ANG-3777 in all therapeutic, prophylactic and diagnostic uses for renal indications, including forms of AKI, and congestive heart failure (collectively, the Renal Indications). Pursuant to the Vifor License, we received an upfront license payment of $30 million in November 2020, and a $30 million equity investment, $5 million of which we received in January 2021 and $25 million of which we received contemporaneously with the closing of our Initial Public offering (IPO). Although the Vifor License includes additional milestone and royalty objectives, we do not expect to receive any clinical, post-approval, or sales milestones, or royalties, as we do not intend to continue to pursue the clinical development plan set forth in the Vifor License. In 2022, we and Vifor Pharma continue to complete planned analyses of the results of the clinical trials announced in the fourth quarter of 2021 and discuss the future of the collaboration on the basis of such analyses.
Our Preclinical Pipeline
We have a wholly-owned preclinical pipeline of internally-developed programs, including a ROCK2 inhibitors programs for fibrotic diseases, and CYP11B2 inhibitor program. Our goal is to select clinical lead candidates for one or more of these programs and begin IND-enabling studies by the end of 2022.
ROCK2 Inhibitors for Fibrotic Diseases. Our ROCK2 program includes a number of highly selective, oral small molecule inhibitors of ROCK2 developed internally as a potential treatment for fibrotic and other diseases. Rho-associated coiled-coil forming protein kinase (ROCK) signal transduction pathways are implicated in the development of fibrosis. Inhibition of ROCK isoforms ROCK1 and ROCK2 has shown promise in fibrosis and dual
ROCK1/ROCK2 inhibitors have been used to treat conditions including hemorrhagic stroke and glaucoma. However, ROCK1 inhibition has been associated with hypotension (low blood pressure) and enhanced vascular permeability. Recent scientific work using specific genetic or pharmacological reduction of ROCK2 indicates ROCK2 inhibition by itself can result in anti-fibrotic activity without causing hypotension. These findings informed our strategy to develop a ROCK2-specific inhibitor, with the goal of minimizing ROCK1 inhibition, as a potential treatment for fibrosis and other diseases. We believe this approach could translate into a product candidate with enhanced tolerability potentially supporting long-term systemic use. We hold global rights to our ROCK2 inhibitor program.
CYP11B2 Inhibitors. We have created a selection of molecules with high specificity to CYP11B2 (aldosterone synthase) relative to CYP11B1, which we are investigating for the purpose of targeting aldosterone-related diseases, which include resistant hypertension, congestive heart failure, renal fibrosis and primary hyperaldosteronism. We hold global rights to our CYP11B2 inhibitor program.
Commercialization
Our lead product candidate, ANG-3070, is a highly selective, oral small molecule TKI we are developing as a potential treatment for fibrotic diseases, particularly of the kidney and lung. We reported positive data from a Phase 1 healthy volunteer study in August of 2021 and have enrolled the first patients in JUNIPER, a randomized, multi-center, double-blind, and placebo-controlled global dose-finding Phase 2 trial to evaluate ANG-3070 in patients with primary proteinuric kidney diseases (PPKDs). We hold global rights to ANG-3070, including all commercial rights. As we advance the program, we will evaluate how to successfully commercialize ANG-3070. We do not intend to continue the clinical development plan for ANG-3777 set forth in the Vifor License, which had included a Phase 3 study in CSA-AKI and a Phase 4 confirmatory study in DGF.
Management
Our pipeline and company strategy were originated and are supported by a management team with extensive experience and expertise in clinical research and development, business development, and commercialization. Our President and Chief Executive Officer, Jay Venkatesan, M.D., was the founder and CEO of Alpine BioSciences (acquired by Cascadian Therapeutics, which was subsequently acquired by Seagen), was a key investor in Mavupharma Inc. (acquired by AbbVie), and is a former portfolio manager of Ayer Capital and director of Brookside Capital Partners (the hedge fund group affiliated with Bain Capital). Our Chief Medical Officer and Head of Research, John F. Neylan, M.D., is a nephrologist who has held leadership roles at Keryx Biopharmaceuticals, Genzyme Corporation, and Wyeth Corporation. Our Chief Business Officer and General Counsel, Jennifer J. Rhodes, has held leadership roles at Pfizer Inc., Medivation Inc., and Adamas Pharmaceuticals, Inc. These individuals and other members of our senior management team have contributed to the clinical development, registration and/or commercialization of a multitude of approved drug products.
Company History
We were founded in 1998. From our incorporation through 2014, our efforts were primarily focused on researching pathways related to serious organ diseases and applying our medicinal chemistry expertise towards creating potential therapeutics to address the unmet medical needs of patients. Since 2014, we have focused on the clinical development of our ANG-3070 and ANG-3777 programs and translational work necessary to bring our pipeline programs to the clinic. ANG-3070 is now our lead clinical asset.
Our corporate operations are based in San Francisco, California, our clinical development and regulatory teams are primarily located in Boston, Massachusetts, and our discovery and research programs are based in Uniondale, New York.
Our Strategy
We are focused on discovering, developing, and commercializing novel small molecule therapeutics to address fibrotic diseases, particularly of the kidney and lung. Our goal is to transform the treatment paradigm for patients
suffering from these potentially life-threatening conditions for which there are no approved medicines or where existing approved medicines have recognized limitations. The key tenets of our business strategy are to:
▪Develop ANG-3070 in multiple renal fibrosis indications. We believe ANG-3070 can address a large unmet medical need in patients with PPKDs progressing towards renal fibrosis and end-stage renal disease. We are currently enrolling JUNIPER, a global Phase 2 trial of ANG-3070. JUNIPER is a randomized, double-blind, placebo-controlled dose-finding trial intended to assess ANG-3070 in adult patients with FSGS or IgAN, two types of PPKDs. The trial will enroll 100 patients equally among four treatment arms: 200mg ANG-3070 once daily, 400mg ANG-3070 once daily, 300mg ANG-3070 twice daily, and placebo with dosing for 12 weeks. The primary endpoint in the study is the percentage reduction in urinary protein/creatinine ratio (UPCR) at week 12. Topline data from this trial should be available in the first half of 2023.
▪Develop ANG-3070 in Idiopathic Pulmonary Fibrosis. Given multiple animal models demonstrating the activity of ANG-3070 activity in pulmonary fibrosis, we intend to complete IND-enabling work and file an IND by the end of 2022 for a Phase 2 trial of ANG-3070 in IPF, a chronic, life-threatening condition. There are two medicines currently approved for IPF by regulators, pirfenidone and nintedanib. However, we believe additional therapies are needed to treat IPF, since approximately half of IPF patients discontinue taking these approved medicines within one year. Fewer than one-third of IPF patients are currently prescribed pirfenidone or nintedanib. Despite this, the two medicines together are projected to sell $3.8 billion worldwide in 2021.
▪Advancement of our earlier-stage programs. Our ROCK2 inhibitor program is designed to advance a potent and highly selective inhibitor of ROCK2, with minimal inhibition of ROCK1, which we believe could translate into a therapeutic with enhanced tolerability in patients with fibrotic diseases. We are also developing proprietary CYP11B2 inhibitors for the purpose of targeting aldosterone-related diseases. We expect to nominate a lead compound and initiate IND-enabling studies for at least one of these earlier-stage programs by the end of 2022.
Our Pipeline
Our research and development activities are primarily focused on discovering and investigating novel small molecule therapeutics to address fibrotic diseases. All our pipeline programs were developed internally and are wholly owned by Angion. Anticipated milestones are reflected in the chart below:
ANG-3070, Our Lead Product Candidate
Our lead product candidate, ANG-3070, is a highly selective, oral small molecule TKI developed internally as a potential treatment for fibrotic diseases, particularly in the kidney and lung. ANG-3070 has demonstrated positive results in a Phase 1 healthy volunteer study, proof of concept in a variety of animal models as an anti-fibrotic agent, and the ability in vitro to inhibit pro-fibrosis tyrosine kinases at levels achievable with oral administration.
Within fibrosis, we believe there is promising therapeutic potential for ANG 3070 in PPKDs, a group of kidney diseases characterized by excess urinary protein excretion, and in types of pulmonary fibrosis, particularly IPF. In August 2021, we reported positive final data on a Phase 1 study of ANG-3070 in healthy volunteers. In December 2021 we enrolled the first patient in “JUNIPER”, a randomized, multi-center, double-blind, and placebo-controlled
global dose-finding Phase 2 study in PPKD patients focused on FSGS and IgAN. We plan to file an IND for ANG-3070 in IPF by the end of 2022.
Fibrotic Diseases and Tyrosine Kinase Inhibitors
Fibrosis is a part of the body’s natural healing response to organ injury. When it becomes dysregulated, fibrosis can be highly detrimental to a normal organ’s architecture and function, potentially leading to death from organ failure. Two major organs commonly impacted by fibrosis are the kidney and the lung.
Renal or kidney fibrosis is the underlying pathological process leading to progression of chronic kidney disease (CKD), a disease affecting more than 10% of the world’s population, and renal fibrosis is currently also the best predictor of disease progression. No specific anti-fibrotic therapeutics currently exist to combat renal fibrosis.
Pulmonary or lung fibrosis is a disease which occurs when lung tissue becomes damaged or scarred. The resulting thickened, stiff tissue makes it more difficult for lungs to work properly. As pulmonary fibrosis worsens, patients have progressive shortness of breath and face increasing restrictions on activities of daily living. Pulmonary fibrosis is a family of over 200 different diseases, including IPF. At this time, pulmonary fibrosis is not reversible and remains a terminal disease.
TKIs are known to affect a wide array of biochemical pathways, including the mediation of tissue inflammation and fibrosis. TKIs are one of the largest classes of newly approved drugs, with more than 25 approved molecules worldwide targeting pathways believed to affect relevant diseases. However, tyrosine kinases are ubiquitous proteins and there is significant overlap in their structures and binding sites. This can lead to binding against unintended tyrosine kinase targets and these off-target effects are largely responsible for the toxicity associated with TKIs.
ANG-3070 was designed with the intent of having enhanced inhibition of kinases involved in inflammation and the progression of fibrosis while minimizing binding to kinases thought responsible for adverse or off-target effects. Four kinase receptors targeted by ANG-3070 include platelet-derived growth factor receptor alpha and beta (PDGFRα and PDGFRβ, respectively) and Discoidin Domain Receptors 1 and 2 (DDR1 and DDR2). ANG-3070 has demonstrated potent, low nanomolar IC50s (a standard measure of drug potency) to these tyrosine kinase receptors as shown in the figure below. PDGFRα, PDGFRβ, DDR1, and DDR2 are implicated in a number of diseases and targeting them effectively could provide a therapeutic benefit to patients with renal and pulmonary fibrosis.
PDGFRα and PDGFRβ are expressed in renal mesenchymal cells (i.e., glomerular mesangial cells) or cells with stem-cell like properties capable of maturing into a variety of critical cell types and in vascular smooth-muscle cells. In addition, they are expressed in interstitial cortical fibroblasts forming the skeleton of the kidney and medullary pericytes responsible for blood flow through the kidneys. In human renal disease, PDGFRα is upregulated in glomerulus as well as arterial smooth muscle cells and endothelial cells. Activation of PDGFRβ
specifically in renal mesenchymal cells is sufficient to induce and drive progressive glomerulosclerosis and interstitial renal fibrosis. Being able to downregulate or prevent these targets could be beneficial to patients with related renal diseases.
In patients with early, but not late stage, IPF, cells responsible for the ability of the lung to exchange oxygen, cells lining the inside of blood vessels, and fibroblasts making up the structure of the lung express increased PDGFRβ. PDGFRα is expressed in these same cells in IPF patients, plus in lung immune cells. During pulmonary fibrosis, both PDGFRα and PDGFRβ are involved in pro-fibrotic activity, suggesting a therapy specific to these targets might exert beneficial anti-fibrotic effects for patients with IPF.
DDR1 is a tyrosine kinase transmembrane receptor of collagens, expressed in several cell types and organs, including the gastrointestinal tract, brain, lung, mammary gland, and kidney. Despite collagen being the most abundant protein in the body, DDR1 is not induced or activated under normal conditions. Several studies show DDR1 is overexpressed in pathological conditions and participates in tissue adaptation to acute and chronic inflammatory lesions, including renal inflammation and fibrosis. In a mouse model of Alport’s Syndrome (AS), for example, deletion of DDR1 delays renal fibrosis. Other animal studies suggest DDR1 could play an important role in IPF, mediating the creation of permanent pulmonary surface cell lesions. Targeting DDR1 with an effective therapeutic would help reduce some of the adverse effects related to DDR1 activation, potentially helping patients with DDR1-related diseases.
In contrast to DDR1’s primary expression in epithelial cells and activation by multiple types of collagens, DDR2 is abundantly expressed in fibroblasts. In the early phase of fibrosis in IPF, TGF-β induces expression of DDR2 in lung fibroblasts and synergizes with the resulting downstream signals to accelerate formation of fibrotic tissue. In later stages of fibrosis with the fibrotic process is already established, the DDR2/ERK axis promotes the oversynthesis of extracellular matrix components, resulting in massive fibrosis. Given these roles in pro-fibrotic pathways, targeting DDR2 could help prevent or reduce fibrosis in patients with chronic fibrotic disease.
Disease Overviews and Markets
Our lead product candidate, ANG-3070, is a highly selective, oral small molecule TKI developed internally as a potential treatment for renal and pulmonary fibrosis. In December 2021, we enrolled the first patient in “JUNIPER” a randomized, multi-center, double-blind, and placebo-controlled global dose-finding Phase 2 study in PPKD patients with FSGS and IgAN. We plan to file an IND for ANG-3070 in IPF at the end of 2022.
Primary Proteinuric Kidney Disease (PPKD)
A common thread among certain kidney diseases is the presence of abnormal levels of protein in the urine, or proteinuria. This is an indication of damaged kidneys and the presence of potentially serious disease. PPKDs share proteinuria as the common primary means of diagnosis.
Despite the differences in root causes among various PPKDs, they have a common path of disease progression as seen in the figure below. PPKDs typically move from proteinuria, through the development of fibrosis, chronic kidney disease, and eventually to end-stage renal disease and kidney failure resulting in transplantation or death. Therefore, we are developing ANG-3070 to address the fibrosis experienced by PPKD patients regardless of the root etiology of their specific condition.
Four types of PPKDs include IgA nephropathy, Alport Syndrome, Focal Segmental Glomerulosclerosis, and Membranous Nephropathy.
Focal Segmental Glomerulosclerosis (FSGS) is a rare form of nephrotic disease (disease in which kidney damage allows proteins to leak into the urine) in which scar tissue develops in the glomeruli, the structures in the kidneys responsible for filtering waste from the blood. FSGS accounts for about 40% of adults with nephrotic syndrome and about 20% of children with nephrotic syndrome. In many cases, the cause of FSGS is unknown (idiopathic). In other cases, the scarring may occur because of another condition such as HIV infection, sickle cell disease, obesity, autoimmune diseases, or genetic causes. It is estimated that FSGS affects up to 40,000 patients in the United States, with a similar prevalence in Europe. More than 5,400 patients in the United States are diagnosed with FSGS every year, a number likely underestimated because of the limited number of biopsies performed to confirm the diagnosis. The disease adversely affects those of African descent more than other demographics. Current treatments for FSGS, corticosteroids and immunosuppressive drugs, are effective only in 25% to 35% of patients. Both of these therapeutic options were developed decades ago for non-renal indications and have been repurposed for FSGS given no approved therapy currently exists for this indication.
IgA nephropathy (IgAN) is the most common glomerulonephritis (GN, the inflammation of the cells in the kidney responsible for filtering the blood) globally and is responsible for between 10% and 20% of all GN in the United States. The prevalence in estimated at up to 150,000 in the United States. IgAN is caused by deposits of immunoglobulin A in the glomeruli caused by aberrant glycosylation, thereby disrupting renal function and causing blood in the urine (hematuria) and proteinuria. IgAN progresses steadily over time, with approximately 30% to 40% of patients developing ESRD over 20 to 30 years, including 20% of children who develop ESRD within 20 years of diagnosis. In 2021, the FDA granted accelerated approval for budesonide, a type of corticosteroid addressing the inflammatory component of IgAN, for IgAN patients based upon a percentage reduction in protein to creatinine ratio at nine months.
Membranous Nephropathy (MN) occurs when the glomeruli become damaged or thickened resulting in proteinuria. MN is often caused by some type of autoimmune activity. As protein leakage increases, so does the risk of long-term kidney damage. In the U.S., it is estimated around 3,000 patients per year will be diagnosed with MN, with an estimated prevalence of under 40,000. There are currently no approved drugs for MN.
Alport Syndrome (AS) is a genetic renal disease and is the second most common inherited cause of kidney failure. AS affects approximately 30,000 to 60,000 people in the United States. AS is caused by a genetic defect in type IV collagen, a component of the glomerular basement membrane in the kidney, resulting in defects in its structure and function. In some patients with inherited AS, the disease can progress very rapidly leading to kidney failure in early adulthood. As in other forms of PPKD, progressive fibrosis plays an important role in the pathophysiology and progression of AS. With no currently approved therapies to stop progressive loss of kidney function, AS represents a rare disorder with significant unmet need.
Pulmonary Fibrosis
Pulmonary fibrosis is characterized by progressive scarring (fibrosis) of the lungs, which leads to their deterioration and destruction. Over time, patients’ lung scarring progresses and breathing becomes difficult, often resulting in the lungs failing to take in enough oxygen to meet the body’s needs.
IPF is an aggressive form of pulmonary fibrosis with a median survival of two to three years from diagnosis. The course of the disease is highly variable. Certain patients become seriously ill within a few months, while others may survive for five years or longer. Most deaths in IPF occur from progression of pulmonary fibrosis leading to respiratory failure. According to the NIH, approximately 140,000 people in the United States have IPF, and approximately 30,000 to 40,000 new cases are diagnosed each year, usually affecting people between the ages of 50 to 70. EU incidence rates are estimated to be similar. Over half are undiagnosed in the mild category alone, while more could be underdiagnosed. The disease is of unknown cause and represents an important area of unmet medical need.
Systemic sclerosis with interstitial lung disease is a complex immune disorder characterized by progressive pulmonary fibrosis. Systemic sclerosis (SSc), also known as scleroderma, is caused by dysfunctional interplay between fibrosis, vascular, and immunological pathways. Interstitial lung disease (ILD) is a common complication of systemic sclerosis and is its leading cause of morbidity and mortality accounting for 35% of disease specific mortality. SSc-ILD usually develops within the first five years of the disease, with 30-40% of SSc patients developing
clinically significant SSc-ILD. The U.S. prevalence of SSc-ILD is estimated to be over 60,000 with about 9,000 diagnosed each year.
There are currently two approved therapies for IPF, pirfenidone (Esbriet®, sold by Roche/Genentech) and the kinase inhibitor nintedanib (OFEV®, sold by Boehringer-Ingelheim). Nintedanib is also approved for SSc-ILD patients. Both drugs have known tolerability challenges for patients. Diarrhea and nausea are very common side effects, with 62% of patients taking nintedanib reporting diarrhea and 29% reporting nausea according to its drug label. Similarly, diarrhea was reported by 26% and nausea by 36% of patients taking pirfenidone according to its label. Patient convenience is also a recognized challenge, with nintedanib required to be dosed twice per day with food and pirfenidone three times per day with food after a three-step titration over the first two weeks. Patient drop-out rates for both drugs are substantial, with 43.8% of patients on nintedanib and 51.5% of patients on pirfenidone dropping out after 12 months. Neither therapy demonstrated an impact on patient survival in the clinical trials forming the basis for their approval. Due to the recognized limitations of these approved medicines, under 30% of U.S. patients diagnosed with IPF, despite it being a life threatening disease, are prescribed nintedanib or pirfenidone.
Despite these drawbacks to tolerability, convenience, and efficacy, pirfenidone and nintedanib generated approximately $3.8 billion in combined 2021 worldwide sales. If we are able to demonstrate in clinical trials ANG-3070 provides IPF patients with an alternative treatment option with a more acceptable tolerability, convenience, and/or efficacy profile, we would expect ANG-3070, if approved, to compete successfully with these two approved medicines. However, there is no guarantee ANG-3070 will be able to achieve these goals or, if it does, generate comparable revenues.
Our Solution: ANG-3070 for the Treatment of Renal and Pulmonary Fibrosis
By targeting tyrosine kinases receptors involved in fibrogenesis such as PDGFRα, PDGFRβ, DDR1, and DDR2, ANG-3070 could be an important potential therapeutic addressing a number of fibrotic conditions in the kidney and lung.
In August 2021, we reported positive final data from a Phase 1 study of ANG-3070 in healthy volunteers. Key findings from the study included:
•ANG-3070 achieved drug exposures in humans exceeding exposures in which activity was demonstrated in animal models of proteinuric kidney diseases
•Encouraging safety and tolerability profile, particularly given the well-recognized incidence and severity of gastrointestinal side effects in approved TKIs
•Pharmacokinetic data supportive of potential once-daily oral dosing for ANG-3070
As represented in the figure below, in Part A, healthy volunteers were given ascending single doses of ANG-3070 ranging from 50 mg to 600 mg to assess the safety, tolerability, pharmacokinetics and food effect of ANG-3070 at different doses. In Part B, healthy volunteers were given either twice-daily doses ranging from 50 mg to 500 mg under fasting conditions over two weeks or once-per-day doses ranging of 400 mg and 600 mg with meals over two weeks.
ANG-3070 was generally well-tolerated at all doses and there were no Serious Adverse Events reported at any dose schedule or level. The reported (non-serious) Adverse Events (AEs) were seen mostly at higher doses, 600 mg administered once daily and 500 mg administered twice daily over two weeks. These AEs included nausea, abdominal cramps, and diarrhea. Generally, these AEs were mild to moderate.
Pharmacokinetic highlights from the Phase 1 study included:
•ANG-3070 was rapidly absorbed within 1-2 hours under fasting conditions;
•Dosing with food delayed absorption to 3-4 hours with no change in exposure but lower incidence of nausea when given with food;
•Mean half-life (T1/2) of 15-21 hours and small/no accumulation in blood after 14 days supports either once or twice per day dosing; and
•Urinary excretion less than 3%, suggesting dose reduction in patients with kidney disease may not be required
An important finding from the Phase 1 study was human exposure levels as measured by AUC between 0-24 hours after dosing exceeded active exposure levels seen in the preclinical animal studies of ANG-3070. The figure below compares exposure levels in the passive Heymann’s nephritis rat model of MN with the exposure levels seen in the Phase 1 study. The blue box indicates the dose range where ANG-3070 was demonstrated to be active in the MN rat model. The pair of bars on the left side notes a 15 mg/kg dose in rats provided equivalent drug exposure to 3 mg/kg or about 200 mg once daily dose in humans. The next set of bars to the right show the upper end of a 50 mg/kg dose in rats was equivalent to the 6mg/kg or about 400 mg once daily in humans. A human dose of 250 mg twice a day, which was well-tolerated in the Phase 1 study, provides ANG-3070 exposures well above those seen as necessary for activity in animal models. Finally, the multi-colored bar on the right side of the graph shows the no adverse event level in non-human primates was not seen until about 250 mg/kg, or an equivalent human dose of about 5,600 mg once daily. Taken together, these exposure data demonstrate a large margin between doses seen as active in animal studies and much higher dose levels required to show toxicity in animal models.
Based upon the Phase 1 study data, in December 2021 we enrolled the first patient in JUNIPER, a randomized, multi-center, double-blind, and placebo-controlled global Phase 2 dose finding study in PPKD patients focused on FSGS and IgAN. The study plan is to enroll appropriately 100 patients at a 1:1:1:1 ratio to ANG-3070, 200 mg QD (once daily), 400 mg QD, 300 mg BID (twice daily), or placebo (QD or BID) administered daily for 12 weeks. The primary endpoint is the percentage change in urinary protein/creatinine ratio (UPCR) at week 12.
Key enrollment criteria for the study include:
•Diagnosis of IgAN or primary FSGS confirmed by past renal biopsy or genetic forms of FSGS on standard of care (SoC) for at least 12 weeks prior to enrollment
•eGFR > 40mL/min/1.73m2, urinary protein > 1g/day, stable blood pressure, SoC background therapy of ACEi or ARB with up to 20 patients with and eGFR > 30 but < 40mL/min/1.73m2
•Any other RAAS/SGLT-2/immunomodulatory medications must be stable for prior 12 weeks.
The goals of the JUNIPER study are:
•Provide enough information of effect of ANG-3070 on proteinuria to determine a regulatory strategy in PPKD patients
•Determine the proper dose for subsequent studies
•Discover whether the proper dose may be different for IgAN patients than FSGS patients
•Gather additional safety, tolerability, biomarker, and PK/PD data on ANG-3070
We are also planning a Phase 1B study in patients with IPF, to begin in 2022. The preliminary plan is to enroll IPF patients who are either treatment naïve or have been proven intolerant of approved therapies to evaluate the pharmacokinetics and safety and tolerability of ANG-3070. Subsequently, we are planning a Phase 2 study where the primary endpoint is likely to be pulmonary function tests at 6-12 months and we expect this trial to also compare multiple doses of ANG-3070 against placebo.
In addition to the Phase 1 data in healthy volunteers, the clinical plans for ANG-3070 in kidney and pulmonary fibrosis are supported by a broad program of preclinical animal studies. ANG-3070 has demonstrated activity in preclinical models across renal and pulmonary fibrosis.
ANG-3777
ANG-3777 was designed to be a first-in-class hepatocyte growth factor (HGF) mimetic. We engineered ANG-3777 to mimic the biological activity of HGF in activating critical pathways in the body’s natural organ repair process following an acute organ injury. In 2021, we reported the results of three clinical trials of ANG-3777. None of the trials were positive on their primary endpoints, but we believe ANG-3777 demonstrated biologic activity in the Phase 3 trial of kidney transplant patients with delayed graft function (DGF) and in the Phase 2 trial in patients at risk for acute kidney injury associated with cardiac surgery involving cardiopulmonary bypass (CSA-AKI).
We continue to work with our license partner Vifor Pharma on the process of closing out our analyses of data from the 2021 clinical trial readouts. We do not intend to continue the clinical development plan for ANG-3777 set forth in the Vifor License, which had included a Phase 3 study in CSA-AKI and a Phase 4 confirmatory study in DGF, given these clinical results. There are no funds budgeted for additional clinical trials for ANG-3777.
Our Preclinical Pipeline
We plan to select clinical lead candidates for one or more of these preclinical programs and begin IND-enabling studies by the end of 2022.
ROCK2 Program for Fibrotic and Other Diseases
Our ROCK2 program includes a number of highly selective, oral, small molecule inhibitors of ROCK2 developed internally as a potential treatment for fibrotic and other diseases. Rho-associated coiled-coil forming protein kinase (ROCK) signal transduction pathways are implicated in the development of fibrosis. Inhibition of the ROCK isoforms ROCK1 and ROCK2 has shown promise in treating fibrosis in animal models. However, use of a non-isoform-specific ROCK inhibitor (i.e., dually inhibits ROCK1 and ROCK2) has been associated with inducing hypotension. Recent scientific work using specific genetic or pharmacological inhibition of ROCK2 indicates ROCK2 inhibition alone can result in anti-fibrotic activity without causing hypotension. These findings informed our strategy to develop ROCK2-specific inhibitors as a potential treatment for fibrosis.
Multiple dual ROCK1/2 inhibitors have received regulatory approval, including ripasudil (Glanatec®), which is approved in Japan for treating glaucoma and ocular hypertension, fasudil (ErilTM), which is approved in Japan and
China for treating cerebral vasospasm in hemorrhagic stroke, and netarsudil (Rhopressa®), which is approved in the United States for the treatment of glaucoma. The ROCK2-selective inhibitor belumosudil has been approved by the FDA for the treatment of chronic graft-versus-host disease.
Elevated expression of ROCK2 has been implicated in a number of chronic fibrotic conditions and other diseases. ROCK2 is significantly upregulated in fibrotic kidneys in both pediatric and adult patients, with ROCK2 levels positively correlated with the severity of the fibrosis. Study of ROCK2 inhibition in the unilateral ureteral obstruction (UUO) model of renal fibrosis showed ROCK2 inhibition alleviates renal fibrosis. Furthermore, in a mouse model of IPF, researchers found mice with either ROCK1 or ROCK2 genetically deleted were protected from bleomycin-induced IPF, indicating specifically targeting either ROCK isoform would be an effective therapeutic strategy against IPF. ROCK2 expression in vitro has also been associated with co-expression of fibrotic liver markers. Elevated ROCK2 levels are seen in cardiac hypertrophy, cardiac fibrosis and diastolic dysfunction. ROCK2 has also been shown to play a role in neurodegenerative disorders such as amyotrophic lateral sclerosis, Parkinson's disease and Alzheimer's disease. As a result, we believe a potent ROCK2 inhibitor should prevent disease progression in chronic fibrotic diseases and potentially be useful in a variety of other cardiac and neurodegenerative disorders.
Dual ROCK1/2 inhibitors can have problematic side effects including hypotension and increased vascular permeability. In an in vitro analysis measuring binding affinity for ROCK2 and ROCK1, our ROCK2 selective inhibitors show much stronger binding affinity for ROCK2 versus ROCK1. We believe high selectivity for ROCK2 could provide enhanced tolerability, potentially supporting long-term systemic use.
CYP11B2 (Aldosterone Synthase) Inhibitor Program
Aldosterone is a hormone produced in the adrenal glands which helps control the body's blood pressure by causing the kidneys to retain salt and excrete potassium, thereby increasing water retention, blood volume and blood pressure. CYP11B2 is a member of the broad cytochrome P450 family and is responsible for the biosynthesis of aldosterone. There are a number of diseases associated with dysregulated aldosterone, including primary hyperaldosteronism (Conn's Syndrome), refractory hypertension, congestive heart failure and kidney fibrosis. As a result, we believe inhibition of CYP11B2 could potentially be used in aldosterone-related diseases.
The renin-angiotensin-aldosterone system (RAAS) is responsible for producing aldosterone to maintain blood pressure. Two major approaches to modulating the RAAS pathway are angiotensin converting enzyme inhibitors (ACE inhibitors) and angiotensin receptor blockers (ARBs). There are eighteen FDA-approved ACE inhibitors/ARBs, and while these drugs are generally quite effective in controlling hypertension, aldosterone breakthrough or escape happens in approximately 10% to 50% of patients depending on the duration of therapy studied and the definition of 'breakthrough'. Aldosterone excess is estimated to be the primary cause in approximately 20% of patients with resistant hypertension, or nearly 2 million patients in the United States alone.
Two hormonal mineralocorticoid receptor antagonists (MRAs), spironolactone and eplerenone, plus a non-steroidal MRA (finerenone), are also involved in blocking the effects of aldosterone. MRAs act by binding to the mineralocorticoid receptor to prevent aldosterone from having its biologic effect on blood pressure and renal excretion and absorption of salt and potassium. However, approved MRAs have the downside of increasing circulating levels of aldosterone, leading to increased activity of aldosterone through its non-MR mechanisms. Aldosterone acts on the vascular system by inducing oxidative stress, inflammation, fibrosis and endothelial dysfunction through both MR-dependent and MR-independent pathways. As such, increased levels of aldosterone have direct deleterious effects on the progression of congestive heart failure and renal fibrosis.
We have created a selection of molecules with high specificity to CYP11B2 relative to CYP11B1 and continue work towards selecting a clinical lead for the program.
Manufacturing
We rely upon third-party contract manufacturing organizations to manufacture and supply product candidates for our clinical trials, and we will rely on such manufacturers to meet commercial demand. We expect this strategy will enable us to maintain a more efficient infrastructure, avoiding dependence on our own manufacturing facility and equipment, while simultaneously enabling us to focus our expertise on the clinical development and future commercialization of our products. Currently, we rely on and have agreements with a single third-party contract manufacturer to supply the drug substance for ANG-3070 and with a single third-party contract manufacturer to
manufacture all clinical trial supplies of ANG-3070. We currently have sufficient inventory of ANG 3070 to meet all requirements for our planned clinical trials. We expect to qualify additional suppliers for ANG 3070 drug substance and ANG 3070 clinical trials supplies to support future clinical trials, and we expect to enter into commercial supply agreements with such manufacturers prior to any potential approval of ANG 3070. ANG-3070 drug substance is manufactured via conventional organic synthetic procedures, starting from raw materials and reagents commercially available in large quantities. ANG-3070 drug product is manufactured via conventional pharmaceutical processing procedures, employing commercially available excipients and packaging materials. The procedure and equipment employed for manufacture and analysis are consistent with standard organic synthesis or pharmaceutical production, and are transferable to a range of manufacturing facilities, if needed.
We are in discussions with third party manufacturers to identify additional suppliers to produce our other product candidates.
Competition
The biotechnology and pharmaceutical industries are characterized by intense competition and rapid innovation. Although we believe our product candidates offer innovative therapeutic approaches and may provide significant advantages relative to current therapies in the treatment of acute organ damage and our other therapeutic areas, our competitors may be able to develop other compounds, drugs, or therapies capable of achieving similar or better results. Our potential competitors include major multinational pharmaceutical companies, established biotechnology companies, specialty pharmaceutical companies and universities and other research institutions. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large, established companies. We believe the key competitive factors affecting the development and commercial success of our product candidates will be whether or not such product candidates are deemed to be safe and effective by relevant regulatory authorities, as well as their tolerability profile, reliability, convenience of dosing, price, and reimbursement.
With respect to ANG-3070, clinical programs potentially competitive in PPKDs generally focus on immune system modification, repurposed or novel hemodynamic (blood pressure) modifiers, and other approaches. In contrast, we believe ANG-3070 is the only clinical-stage anti-fibrotic in development for PPKDs. Given the disease progression path for PPKDs, programs not specifically addressing renal fibrosis have the potential to be more complimentary than competitive. In 2021, Tarpeyo® (budesonide) from Calliditas was granted accelerated approved by the FDA for IgAN, one form of PPKD. Phase 3 programs in PPKD include:
•Atrasentan from Chinook Pharmaceuticals (IgAN, FSGS, Alport)
•Bardoxolone methyl from Reata Pharmaceuticals (Alport)
•Iptacopan from Novartis (IgAN)
•Narsoplimab form Omeros (IgAN)
•Sibeprenlimab from Visterra/Otsuka Pharmaceuticals (IgAN)
•Sparsenten from Travere Therapeutics (IgAN, FSGS)
•DMX-200 from Dimerix (FSGS)
Phase 3 clinical programs potentially competitive with ANG-3070 in pulmonary fibrosis (IPF and SSc-ILD) include:
•There are two approved therapies, pirfenidone (Esbriet®, sold by Roche/Genentech) for IPF and nintedanib (OFEV®, sold by Boehringer-Ingleheim) for IPF and SSc-ILD.
•ORG-447 from Agomab Therapeutics for IPF
•PLN-74809 from Pliant Therapeutics for IPF
•PRM-151 from Roche/Genentech for IPF
•Taladegib from Endeavor Biosciences for IPF
With respect to competition for our ROCK2 inhibitor program:
•Netarsudil ophthalmic solution from Aerie Pharmaceuticals, Inc. was first approved by the FDA in 2017 as a topical agent for reducing intraocular pressure in patients with open-angle glaucoma and ocular hypertension
•Kadmon Holdings, Inc.'s belumosudil (KD025), a ROCK2 inhibitor with reduced selectivity against ROCK1, in the clinic for several indications, and approved for chronic graft versus host disease
•Fasudil developed by Asahi Kasei approved in Asia is being investigated by Woolsey Pharmaceuticals in ALS, retinopathy of prematurity, and dementia
•CXC007 from Redx Pharma Plc
•Other ROCK2 inhibitors in preclinical development.
Regarding competition for our CYP11B2 inhibitor program:
•CIN-107 from CinCor Pharma is a CYP11B2 inhibitor in multiple Phase 2 trials for resistant hypertension, uncontrolled hypertension, and primary aldosteronism.
•PB6440 from PhaseBio is a CYP11B2 inhibitor preparing for Phase 1 trials in 2022 in treatment resistant hypertension
Across each of our development areas, other, potentially competitive, clinical-stage technologies are being developed. Also, companies developing preclinical molecules could decide to pursue development in our chosen indications and potentially compete with us. This could lead to commercial challenges as well as difficulties enrolling clinical trials if they were to target the same indications we are pursuing.
Intellectual Property
The proprietary nature of, and protection for, our product candidates, processes and know-how are important to our business. We pursue various avenues of intellectual property protection, including consideration of patent, trademark, and trade secret strategies. We have sought patent protection in the United States and internationally for our programs relating to small molecule compounds with our tyrosine kinase inhibitors (including ANG-3070), HGF-like activity (including ANG-3777), our ROCK2 inhibitors and our CYP inhibitors. Our patent strategy seeks to protect our product candidates by filing patent applications, in the United States and in relevant foreign jurisdictions, and we pursue multi-faceted protection, as available, for example to relevant small molecule compounds and analogs, pharmaceutical compositions and related methods of manufacture and use. Our policy is to pursue, maintain and defend patent rights in order to protect the technology, inventions and improvements that are commercially important to our business. We also rely on trade secret protection for certain intellectual property that may be important to the development of our business and expect to pursue trademark registrations for brand names or other text or images that may provide commercial value.
In the United States and worldwide, issued patents have a presumptive term, assuming all maintenance fees are paid, of twenty years from their earliest non-provisional filing date. Certain jurisdictions offer opportunities to extend this term. For example, the U.S. Patent and Trademark Office (USPTO) may add term to a patent (referred to as Patent Term Adjustment) if delays by the USPTO of certain activities exceed prespecified durations, from which delays by the Applicant are subtracted. Additionally, many jurisdictions, including the United States and Europe, provide opportunities for extending the term of patents relating to approved pharmaceutical products or their approved uses. In the United States, a single patent can be extended per approved product, for a period (referred to as Patent Term Extension) of up to five years, depending on the dates of patent issuance relative to submission of an application for premarketing approval (i.e., of a New Drug Application or a Biologics License Application) under provisions of the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Act. Similar restoration of term is available in Europe under so-called Supplementary Protection Certificate rights, and extensions under similar policies may be available in other countries.
Depending upon the timing, duration and specifics of FDA marketing approval of our product candidates, if any, one or more of our patents may be eligible for limited Patent Term Extension under the Hatch-Waxman Act in the United States, Supplementary Protection Certificate in Europe.
Our commercial success will depend in part on obtaining and maintaining patent protection and/or other intellectual property protection for our current and future product candidates, including for their use, production, formulation, etc., with commercially relevant terms; our commercial success may also depend in part on our ability to successfully defend our patent and/or other intellectual property rights against third-party challenges. Our ability to stop third parties from making, using, selling, offering to sell and/or importing our products may depend on the extent to which we have rights under valid and enforceable intellectual property rights that cover these activities. We cannot be sure that patents will be granted with respect to any of our pending patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any patents that may be granted to us in the future will be commercially useful in protecting our product candidates, discovery programs and processes. Additionally, we cannot be certain that we will always be able to establish sufficient
ownership rights to ensure complete or necessary control over our intellectual property rights as required in order to obtain, maintain, and/or enforce them. For these and more comprehensive risks related to our intellectual property, please see "Risk Factors—Risks Relating to Our Intellectual Property." The expiration dates of the patents discussed below assume in all cases that the appropriate maintenance, renewal, annuity, or other governmental fees are paid to maintain the patent(s) in force for the full extent of their term and any extension(s) thereof.

Licenses and Collaborations
License Agreement with Vifor Pharma
In November 2020, we granted Vifor Pharma, an exclusive, global (excluding Greater China), royalty-bearing license (the Vifor License), for the commercialization of ANG-3777 in all Renal Indications, beginning with DGF and CSA-AKI. The Vifor License also grants Vifor Pharma exclusive rights, with a right to sublicense subject to our consent for certain specified conditions, to develop and manufacture ANG-3777 for commercialization in Renal Indications worldwide (excluding Greater China) in cooperation with us or independently. We retain the right to develop and commercialize combination therapy products combining ANG-3777 with our other proprietary molecules, subject to Vifor Pharma's right of first negotiation with respect to global (excluding Greater China) rights to such combination therapy products in the Renal Indications. See Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations. Although the Vifor License includes additional milestone and royalty objectives, we do not expect to receive any clinical, post-approval, or sales milestones, or royalties, as we do not intend to continue to pursue the clinical development plan for ANG-3777 , which had included a Phase 3 study for CSA-AKI and a phase 4 confirmatory study in DGF.. We and Vifor continue to complete the planned analyses of the results of the clinical trials announced in the fourth quarter of 2021 and discuss the future of the collaboration.
Collaboration with the University of Michigan
In 2019, we entered into a subcontractor agreement with The Regents of the University of Michigan (UM),
under which we provide funding for identification of ANG-3070-responsive disease marker profiles in rodent models, and their intersection with existing data on patients with various forms of nephrotic kidney disease, to identify potential ANG-3070-responsive patient subsets. Under this agreement we obtain access to the Nephrotic Syndrome Study Network (NEPTUNE), an integrated group of academic centers, patient support organizations and clinical resources dedicated to advancing the treatment of kidney disorders. The goal of work under this agreement, which we support through a grant from the U.S. Department of Defense, is to identify human disease and drug response profiles based upon the genes, networks and pathways that correlate with the therapeutic activity of ANG-3070 in primary FSGS and other fibrotic renal diseases. We are obligated to provide to UM up to a total of $520,000 over the course of the project. We have an option to license and commercialize intellectual property generated during the term of the agreement that is solely owned by UM under commercially reasonable terms. See Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations. On March 21, 2022, Angion provided written notice to UM of its intention to terminate the subcontractor agreement as Angion believes the work under the related U.S. Department of Defense grant to be complete.
License Agreement with Ohr Cosmetics LLC.
In November 2013, we granted Ohr an exclusive worldwide license, with the right to sublicense, under our patent rights covering one of our CYP26 inhibitors, for the use in treating conditions of the skin or hair. Sublicensees may not grant further sublicenses under our patent rights other than to affiliates of such sublicensees and entities with which sublicensees are collaborating for the research, development, manufacture and commercialization of the products. Ohr will pay us a royalty at a rate in the low single digits on gross revenue of products incorporating ANG‑3522, and milestone payments potentially totaling up to $9.0 million based on achievement of sales milestones. Royalties and milestone payments will be paid until the later of 15 years from the first commercial sale of a licensed product or the last to expire licensed patent rights. The royalty rate is subject to adjustments under certain circumstances. The Ohr License represents a related-party transaction, as discussed in Note 15 in this Annual Report on Form 10-K below, and we believe the Ohr License was made on terms no less favorable to us than those we could obtain from unaffiliated third parties. No revenue from this license agreement was recognized during the year ended December 31, 2021.
Government Regulation and Product Approval
The FDA and other regulatory authorities at federal, state, and local levels, as well as in foreign countries, extensively regulate, among other things, the research, development, testing, manufacture, storage, recordkeeping, approval, labeling, marketing and promotion, distribution, post-approval monitoring and reporting, sampling, and import and export of drugs, such as those we are developing. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources.
U.S. Drug Regulation
In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act and its implementing regulations. FDA approval is required before any new drug can be marketed in the United States. Drugs are also subject to other federal, state and local statutes and regulations. Failure to comply with applicable FDA or other requirements may subject a company to a variety of administrative or judicial sanctions, such as FDA clinical holds, refusal to approve pending applications, withdrawal of an approval, warning or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, civil penalties and criminal prosecution.
The process required by the FDA before product candidates may be marketed in the United States generally involves the following:
▪completion of preclinical laboratory tests and animal studies, all performed in accordance with the FDA's Good Laboratory Practice (GLP) regulations;
▪submission to the FDA of an investigational new drug application (IND) which must become effective before human clinical studies may begin and must be updated annually or when significant changes are made;
▪approval by an independent institutional review board (IRB) representing each clinical site before a clinical study may be initiated;
▪performance of adequate and well-controlled human clinical trials in accordance with good clinical practice (GCP) regulations to establish the safety and efficacy of the product candidate for each proposed indication;
▪preparation of and submission to the FDA of a new drug application (NDA);
▪satisfactory completion of an FDA advisory committee review, if applicable;
▪a determination by the FDA within 60 days of its receipt of an NDA to file the application for review;
▪satisfactory completion of an FDA pre-approval inspection of the manufacturing facility(ies) where the product is manufactured to assess compliance with current good manufacturing practice (cGMP) regulations, and of selected clinical investigation sites to assess compliance with GCP; and
▪FDA review and approval of an NDA to permit commercial marketing of the product for its particular labeled uses in the United States.
Preclinical and Clinical Studies
The preclinical and clinical testing and approval process can take many years and the actual time required to obtain approval, if any, may vary substantially based upon the type, complexity and novelty of the product or condition being treated.
Preclinical tests include laboratory evaluation of product chemistry, formulation and toxicity, as well as animal studies to assess the characteristics and potential safety and efficacy of the product. The conduct of preclinical tests must comply with federal regulations and requirements, including GLP. The results of preclinical testing are submitted to the FDA as part of an IND along with other information, including information about product chemistry, manufacturing and controls and any available human data or literature to support use of the product in humans. Long-term preclinical tests, such as animal tests of reproductive toxicity and carcinogenicity, may continue after the IND is submitted.
The central focus of an IND submission is on the general investigational plan and the protocol(s) for human studies. An IND must become effective before human clinical trials may begin. An IND will automatically become effective 30 days after receipt by the FDA, unless before that time the FDA raises concerns or questions related to the proposed clinical studies. In such a case, the IND may be placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before clinical studies can begin. A separate submission to an existing IND must also be made for each successive clinical trial conducted during product development along with any subsequent changes to the investigational plan.
Clinical studies involve the administration of the investigational new drug to human subjects under the supervision of qualified investigators in accordance with GCPs, which include the requirement that all research subjects provide their informed consent for participation in each clinical study. Clinical studies are conducted under protocols detailing, among other things, the objectives of the study, the parameters to be used in monitoring safety and the efficacy criteria to be evaluated. A protocol for each clinical study and any subsequent protocol amendments must be submitted to the FDA as part of the IND. Additionally, approval must also be obtained from each clinical study site's IRB before a study may be initiated at the site, and the IRB must monitor the study until completed. Each year, sponsors must submit an annual progress report to FDA detailing the status of the clinical trial(s) under an IND, and sponsors must timely report to FDA any serious and unexpected adverse reactions, any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol, or any findings from other preclinical or clinical studies that suggest a significant risk in humans exposed to the drug. Sponsors generally must also register and report ongoing clinical studies and clinical study results to public registries, including the website maintained by the U.S. NIH, ClinicalTrials.gov.
For purposes of NDA approval, human clinical trials are typically divided into three or four phases. Although the phases are usually conducted sequentially, they may overlap or be combined.
•Phase 1. The drug is initially introduced into healthy human subjects or into patients with the target disease or condition. These studies are designed to evaluate the safety, dosage tolerance, metabolism and pharmacologic actions of the drug in humans, the side effects associated with increasing doses, and if possible, to gain early evidence on effectiveness.
•Phase 2. The drug is administered to a limited patient population to evaluate dosage tolerance and optimal dosage, identify possible adverse side effects and safety risks and preliminarily evaluate efficacy.
•Phase 3. The drug is administered to an expanded patient population, generally at geographically dispersed clinical study sites to generate enough data to statistically evaluate dosage, clinical effectiveness and safety, to establish the overall benefit-risk relationship of the investigational product and to provide an adequate basis for product approval.
•Phase 4. In some cases, the FDA may condition approval of an NDA for a product candidate on the sponsor's agreement to conduct additional clinical studies after approval. In other cases, a sponsor may voluntarily conduct additional clinical studies after approval to gain more information about the drug. Such post-approval studies are typically referred to as Phase 4 clinical studies.
The FDA, the IRB or the clinical study sponsor may suspend or terminate a clinical study at any time on various grounds, including a finding that the research subjects are being exposed to an unacceptable health risk. We may also suspend or terminate a clinical study based on evolving business objectives and/or competitive climate.
During the development of a new drug, sponsors are given opportunities to meet with the FDA at certain points. These points may be prior to the submission of an IND, at the end of Phase 2 and before an NDA is submitted. Meetings at other times may be requested. These meetings can provide an opportunity for the sponsor to share information about the data gathered to date and for the FDA to provide advice on the next phase of development. Sponsors typically use the meeting at the end of Phase 2 to discuss their Phase 2 clinical results and present their plans for the pivotal Phase 3 clinical trial that they believe will support the approval of the new drug.
Concurrent with clinical trials, companies may complete additional animal studies and develop additional information about the characteristics of the product candidate, and must finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product and, among other things, must include methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the product does not undergo unacceptable deterioration over its shelf life.
Submission of an NDA to the FDA
Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product development and testing are submitted to the FDA in the form of an NDA requesting approval to market the product for one or more indications. The submission of an NDA requires payment of a substantial application user fee to the FDA, unless a waiver or exemption applies.
An NDA must include all relevant data available from pertinent preclinical and clinical studies, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product's chemistry, manufacturing, controls and proposed labeling, among other things. Data can come from company-sponsored clinical studies intended to test the safety and effectiveness of a use of a product, or from a number of alternative sources, including studies initiated by investigators. To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the safety and effectiveness of the investigational product to the satisfaction of the FDA.
The FDA has 60 days from its receipt of an NDA to determine whether the application will be accepted for filing based on the agency's threshold determination that it 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 and is subject to payment of additional user fees. 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 (PDUFA) the FDA has agreed to certain performance goals in the review of NDAs through a two-tiered classification system, standard review and Priority Review. Priority Review designation is given to drugs that offer major advances in treatment, or provide a treatment where no adequate therapy exists. According to PDUFA performance goals, the FDA endeavors to review applications subject to standard review within ten to twelve months, whereas the FDA's goal is to review Priority Review applications within six to eight months, depending on whether the drug is a new molecular entity.
The FDA may refer applications for novel drug products or drug products which present difficult questions of safety or efficacy to an advisory committee for review, evaluation and recommendation as to whether the application should be approved and under what conditions.
Before approving an NDA, the FDA typically will inspect the facility or facilities where the product is manufactured. 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, the FDA will typically inspect one or more clinical sites to assure that relevant study data was obtained in compliance with GCP requirements.
After the FDA evaluates the NDA and conducts inspections of manufacturing facilities, it may issue an approval letter or a complete response letter. A complete response letter indicates that the review cycle of the application is complete and the application is not ready for approval. 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. Even with submission of this additional information, the FDA may ultimately decide that an application does not satisfy the regulatory criteria for approval. If, or when, the deficiencies have been addressed to the FDA's satisfaction in a resubmission of the application, the FDA will issue an approval letter. An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications.
As a condition of NDA approval, the FDA may require a Risk Evaluation and Mitigation Strategy (REMS) program to help ensure that the benefits of the drug outweigh its risks. If the FDA determines a REMS program is necessary during review of the application, the drug sponsor must agree to the REMS plan at the time of approval. A REMS program may be required to include various elements, such as a medication guide or patient package insert, a communication plan to educate healthcare providers of the drug's risks, or other elements to assure safe use, such as limitations on who may prescribe or dispense the drug, dispensing only under certain circumstances, special monitoring and the use of patient registries. In addition, all REMS programs must include a timetable to periodically assess the strategy following implementation.
Further, product approval may require substantial post-approval testing and surveillance to monitor the drug's safety and efficacy, and the FDA has the authority to prevent or limit further marketing of a product based on the results of these post-marketing programs. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not maintained or problems are identified following initial marketing. Moreover, changes to the conditions established in an approved application, including changes in indications, labeling or manufacturing processes or facilities may require submission and FDA approval of a new NDA or NDA supplement before the changes can be implemented. An NDA supplement for a new indication typically requires clinical data similar to that supporting the original approval, and the FDA uses similar procedures in reviewing supplements as it does in reviewing original applications.
Expedited Development and Review Programs
The FDA offers a number of expedited development and review programs for qualifying product candidates, one or more of which may be available for our current or future products.
New drug products are eligible for Fast Track designation if they are intended to treat a serious or life-threatening disease or condition and demonstrate the potential to address unmet medical needs for the disease or condition. Fast Track designation applies to the combination of the product and the specific indication for which it is being studied. The sponsor of a Fast Track product has opportunities for frequent interactions with the review team during product development and, once an NDA is submitted, the product may be eligible for Priority Review. A Fast Track product may also be eligible for rolling review, where the FDA may consider for review sections of the NDA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the NDA, the FDA agrees to accept sections of the NDA and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the NDA.
A product intended to treat a serious or life-threatening disease or condition may also be eligible for Breakthrough Therapy designation to expedite its development and review. A product can receive Breakthrough Therapy designation if 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 designation includes all of the Fast Track program features, as well as more intensive FDA interaction and guidance beginning as early as Phase 1 and an organizational commitment to expedite the development and review of the product, including involvement of senior managers.
After an NDA is submitted for a product, including a product with a Fast Track designation and/or Breakthrough Therapy designation, the NDA may be eligible for other types of FDA programs intended to expedite the FDA review and approval process, such as Priority Review and accelerated approval. A product is eligible for Priority Review if it has the potential to provide a significant improvement in the treatment, diagnosis or prevention of a serious disease or condition compared to marketed products. Depending on whether a drug contains a new molecular entity, Priority Review designation means the FDA's goal is to take action on the marketing application within six to eight months of the 60-day filing date, compared with ten to twelve months under standard review.
Additionally, products studied for their safety and effectiveness in treating serious or life-threatening diseases or conditions may receive accelerated approval upon a determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, 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. As a condition of accelerated approval, the FDA will generally require the sponsor to perform adequate and well-controlled post-marketing clinical studies to verify and describe the anticipated effect on irreversible morbidity or mortality or other clinical benefit. In addition, the FDA currently requires
as a condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial launch of the product.
Orphan Drug Designation
Under the Orphan Drug Act, the FDA may grant Orphan Drug designation to a drug intended to treat a rare disease or condition, which is a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States for which there is no reasonable expectation that the cost of developing and making available in the United States a drug for this type of disease or condition will be recovered from sales in the United States for that drug. Orphan Drug designation must be requested before submitting an NDA. After the FDA grants Orphan Drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. The Orphan Drug designation does not convey any advantage in, or shorten the duration of, the regulatory review or approval process.
If a product with Orphan Drug designation subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to Orphan Drug exclusive approval (or exclusivity), which means that the FDA may not approve any other applications, including a full NDA, to market the same drug for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with Orphan Drug exclusivity. Orphan Drug exclusivity does not prevent FDA from approving a different drug for the same disease or condition, or the same drug for a different disease or condition. Among the other benefits of Orphan Drug designation are tax credits for certain research and a waiver of the application user fee.
A designated Orphan Drug may not receive Orphan Drug exclusivity if it is approved for a use that is broader than the indication for which it received Orphan designation. In addition, exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition.
Pediatric Use and Exclusivity
Even when not pursuing a pediatric indication, under the Pediatric Research Equity Act an NDA or supplement thereto must contain data that is adequate to assess the safety and effectiveness of the drug 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 the enactment of the Food and Drug Administration Safety and Innovation Act in 2012, sponsors must also submit pediatric trial plans prior to the assessment data. Those plans must contain an outline of the proposed pediatric trials the sponsor plans to conduct, including trial objectives and design, any deferral or waiver requests, and other information required by regulation. The FDA must then review the information submitted, consult with the sponsor, and agree upon a final plan. The FDA or the sponsor may request an amendment to the plan at any time. The FDA may, on its own initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until after approval of the product for use in adults, or full or partial waivers from the pediatric data requirements.
Separately, in the event the FDA issues a Written Request for pediatric data relating to a drug product, an NDA sponsor who submits such data may be entitled to pediatric exclusivity. Pediatric exclusivity is another type of non-patent marketing exclusivity which, if granted, provides for the attachment of an additional six months of marketing protection to the term of any existing exclusivity.
Post-Approval Requirements
Once an NDA is approved, a product will be subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to drug listing and registration, recordkeeping, periodic reporting, product sampling and distribution, adverse event reporting and advertising, marketing and promotion. Drugs may be marketed only for the approved indications and in accordance with the provisions of the approved labeling. While physicians may prescribe for off-label uses, manufacturers may only promote for the approved indications and in accordance with the provisions of the approved label. However, companies may share truthful and not misleading information that is otherwise consistent with a product's FDA approved labeling. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability.
After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject to prior FDA review and approval. There also are continuing user fee requirements, under which FDA assesses an annual program fee for each product identified in an approved NDA. In addition, quality-control, drug manufacture, packaging and labeling procedures must continue to conform to cGMPs after approval. Drug manufacturers and certain of their subcontractors are required to register their establishments with the FDA and certain state agencies. Registration with the FDA subjects entities to periodic unannounced and announced inspections by the FDA and these state agencies, during which the agency inspects manufacturing facilities to assess compliance with cGMPs. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon us and any third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance.
The FDA may withdraw approval of a product if compliance with regulatory requirements 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 studies to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:
▪restrictions on the marketing or manufacturing of a product, complete withdrawal of the product from the market or product recalls;
▪fines, warning or untitled letters or holds on post-approval clinical studies;
▪refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of existing product approvals;
▪product seizure or detention, or refusal of the FDA to permit the import or export of products; or
▪injunctions or the imposition of civil or criminal penalties.
The FDA may also require post-approval studies and clinical trials if the FDA finds that scientific data, including information regarding related drugs, deem it appropriate. The purpose of such studies would be to assess a known serious risk or signals of serious risk related to the drug or to identify an unexpected serious risk when available data indicate the potential for a serious risk. The FDA may also require a labeling change if it becomes aware of new safety information that it believes should be included in the labeling of a drug.
The Hatch-Waxman Amendments
ANDA Approval Process
The Drug Price Competition and Patent Term Restoration Act of 1984, known as the Hatch-Waxman Amendments, established abbreviated FDA approval procedures for drugs that are shown to be equivalent to proprietary drugs previously approved by the FDA through the NDA process. Approval to market and distribute these generic equivalent drugs is obtained by filing an abbreviated new drug application (ANDA) with the FDA. An ANDA is a comprehensive submission that contains (among other things), data and information pertaining to the active pharmaceutical ingredient, drug product formulation, specifications and stability of the generic drug, as well as analytical methods, manufacturing process validation data and quality control procedures. However, premarket applications for generic drugs are termed "abbreviated" because they generally do not include preclinical and clinical data to demonstrate safety and effectiveness. Instead, a generic applicant must demonstrate that its product is bioequivalent to a referenced proprietary drug. In certain situations, an applicant may obtain ANDA approval of a generic drug with a strength or dosage form that differs from the referenced proprietary drug pursuant to the filing and approval of an ANDA suitability petition. The FDA will approve the generic product as suitable for an ANDA application if it finds that the generic product does not raise new questions of safety and effectiveness as compared to the innovator product. A product is not eligible for ANDA approval if the FDA determines that it is not equivalent to the referenced proprietary drug or is intended for a different use and it is not otherwise subject to an approved suitability petition. However, such a product might be approved under an NDA, with supportive data from clinical trials.
505(b)(2) NDAs
Section 505(b)(2) of the FDCA, enacted as part of the Hatch-Waxman Amendments, permits the filing of an NDA where at least some of the information required for approval comes from clinical trials not conducted by or for
the applicant and which the applicant has not obtained a right of reference. Section 505(b)(2) can serve as a path to approval for modifications to previously approved drugs, such as new indications, formulations, dosage forms, or other conditions of use. If the 505(b)(2) applicant can establish that reliance on the FDA's previous findings of safety and effectiveness for the approved reference drug is scientifically appropriate, it may eliminate the need to conduct certain preclinical or clinical studies for the new product. The FDA may approve the new product for all, or some, of the label indications for which the reference drug has been approved, as well as for any new indication sought by the 505(b)(2) applicant.
Orange Book Listing
In seeking approval for a drug through an NDA, including a 505(b)(2) NDA, applicants are required to submit certain information to the FDA regarding any patents with claims covering the applicant's product or a method of using the product. Upon approval of the NDA, each of the patents is listed in the FDA's Approved Drug Products with Therapeutic Equivalence Evaluations, known as the Orange Book. Any applicant that subsequently files an ANDA or 505(b)(2) application referencing the approved drug must certify to FDA, with respect to each patent listed for the approved drug in the Orange Book: (1) that no patent information was submitted to the FDA; (2) that such patent has expired; (3) the date on which such patent expires; or (4) that such patent is invalid or will not be infringed by the manufacture, use or sale of the drug product for which the application is submitted. This last certification is known as a "paragraph IV certification." For method of use patents, in lieu of submitting a certification, the applicant may elect to submit a "section viii statement" certifying that its proposed label does not contain (or carves out) any language regarding a patented method of use.
If an ANDA or 505(b)(2) applicant does not challenge one or more listed patents through a paragraph IV certification, the FDA will not approve the ANDA or 505(b)(2) application until all the listed patents claiming the reference product have expired.
If an ANDA or 505(b)(2) applicant provides a paragraph IV certification with its application, the applicant must send notice of the paragraph IV certification to the holder of the NDA for the reference product and all patent holders for the patent at issue within 20 days after the ANDA or Section 505(b)(2) application has been accepted for filing by the FDA. The NDA holder and patent owners may then initiate a patent infringement suit against the ANDA or 505(b)(2) applicant. Under the FDCA, the filing of a patent infringement suit within 45 days of the NDA holder's or patent owners' receipt of the notification regarding the paragraph IV certification automatically prevents the FDA from approving the ANDA or 505(b)(2) application until the earliest to occur of 30 months from the date the paragraph IV notice is received, the expiration of the patent, the settlement of the lawsuit or a court decision that the patent is invalid, unenforceable or not infringed. If the NDA holder or patent owners do not bring a patent infringement suit within the 45-day period, they may later bring a patent infringement suit under traditional patent law, but it will not invoke the 30-month stay of approval.
Separate from applicable patent terms and the 30-month stay of approval for paragraph IV applications, the FDA will also refrain from approving an ANDA or 505(b)(2) application until all applicable non-patent exclusivity for the reference drug has expired.
Non-Patent Exclusivity
NDA holders may be entitled to different periods of non-patent exclusivity, during which the FDA cannot approve an ANDA or 505(b)(2) application that relies on the approved drug. For example, an applicant may obtain five years of non-patent exclusivity upon NDA approval of a new chemical entity (NCE) which is a drug that contains an active moiety that has not been previously approved by the FDA in any other NDA. During the five-year period of NCE exclusivity, the FDA cannot accept any application for a product that contains the same active moiety as the approved NCE; however, the FDA can accept an ANDA or 505(b)(2) application for the same active moiety after a four-year period if such application includes a paragraph IV certification.
In addition, a non-NCE drug may qualify for a three-year period of exclusivity for a change to a previously approved product, such as a new indication or condition of use, if one or more new clinical studies (other than bioavailability or bioequivalence studies) was essential to the approval of the application and was conducted or sponsored by the applicant. In such case, the FDA is precluded from approving any ANDA or 505(b)(2) application for the protected modification until after the three-year exclusivity period has concluded. However, unlike NCE exclusivity, the FDA can accept an application and being the review process during the exclusivity period.
Other types of non-patent exclusivity include seven-year Orphan Drug exclusivity and six-month pediatric exclusivity (each discussed above).
International Regulation
In addition to regulations in the United States, we could become subject to a variety of foreign regulations regarding development, approval, commercial sales and distribution of our products if we seek to market our product candidates in other jurisdictions. Whether or not we obtain FDA approval for a product, we must obtain the necessary approvals by the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the product in those countries. The approval process varies from country to country and can involve additional product testing and additional review periods, and the time may be longer or shorter than that required to obtain FDA approval. The requirements governing, among other things, the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country. Regulatory approval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country may negatively impact the regulatory process in others. If we fail to comply with applicable foreign regulatory requirements, we may be subject to fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.
Other Healthcare Laws
In addition to FDA restrictions on the marketing of pharmaceutical products, other foreign, federal and state healthcare regulatory laws restrict business practices in the pharmaceutical industry. These laws include, but are not limited to, federal and state anti-kickback, false claims, data privacy and security, and physician payment and drug pricing transparency laws.
The federal Anti-Kickback Statute prohibits, among other things, any person or entity from knowingly and willfully offering, paying, soliciting, receiving or providing any remuneration, directly or indirectly, overtly or covertly, to induce or in return for purchasing, leasing, ordering, or arranging for or recommending the purchase, lease, or order of any good, facility, item or service reimbursable, in whole or in part, under Medicare, Medicaid or other federal healthcare programs. The term "remuneration" has been broadly interpreted to include anything of value. The Anti-Kickback Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers, formulary managers and beneficiaries on the other hand. Several courts have interpreted the statute's intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the statute has been violated. In addition, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. The majority of states also have anti-kickback laws, which establish similar prohibitions, and in some cases may apply to items or services reimbursed by any third-party payor, including commercial insurers.
The federal False Claims Act prohibits, among other things, any person or entity from knowingly presenting, or causing to be presented, a false, fictitious or fraudulent claim for payment to, or approval by, the federal government, knowingly making, using, or causing to be made or used a false record or statement material to a false or fraudulent claim to the federal government, or knowingly making a false statement to avoid, decrease or conceal an obligation to pay money to the U.S. federal government. A claim includes "any request or demand" for money or property presented to the U.S. government. Actions under the civil False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of the government. Moreover, a claim including items or services resulting from a violation of the U.S. federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act.
The civil monetary penalties statute imposes penalties against any person who is determined to have presented or caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent.
The federal Health Insurance Portability and Accountability Act of 1996 (HIPAA) created additional federal criminal statutes that prohibit, among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense, and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare
benefits, items or services. Similar to the U.S. federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their implementing regulations, impose privacy, security and breach reporting obligations with respect to individually identifiable health information upon entities subject to the law, such as health plans, healthcare clearinghouses and certain healthcare providers, known as covered entities, and their respective business associates and their covered subcontractors that perform services for them that involve individually identifiable health information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in U.S. federal courts to enforce HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions.
In addition, there has been a recent trend of increased federal and state regulation of payments made to physicians and certain other healthcare providers. The Affordable Care Act, as amended by the Health Care Education and Reconciliation Act (Affordable Care Act), imposed, among other things, new annual reporting requirements through the Physician Payments Sunshine Act for covered manufacturers for certain payments and "transfers of value" provided to physicians (as defined by statute), certain other health care professionals, and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members. In addition, certain states require implementation of compliance programs and compliance with the pharmaceutical industry's voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, impose restrictions on marketing practices and/or require the tracking and reporting of marketing expenditures and pricing information as well as gifts, compensation and other remuneration or items of value provided to physicians and other healthcare professionals and entities.
Violations of fraud and abuse laws, including state anti-kickback and false claims laws, some of which apply to items or services reimbursed by any third-party payor, including commercial insurers, may be punishable by criminal and civil sanctions, including fines and civil monetary penalties, the possibility of exclusion from federal healthcare programs, including Medicare and Medicaid, disgorgement and corporate integrity agreements, which impose, among other things, rigorous operational and monitoring requirements on companies. Similar sanctions and penalties, as well as imprisonment, also can be imposed upon executive officers and employees of such companies.
Coverage and Reimbursement
Sales of any pharmaceutical product depend, in part, on the extent to which such product will be covered by third-party payors, such as federal, state and foreign government healthcare programs, commercial insurance and managed healthcare organizations, and the level of reimbursement for such product by third-party payors. Significant uncertainty exists as to the coverage and reimbursement status of any newly approved product. Decisions regarding the extent of coverage and amount of reimbursement to be provided are made on a payor-by-payor basis. One third-party payor's decision to cover a particular product does not ensure that other payors will also provide coverage for the product. As a result, the coverage determination process can require manufactures to provide scientific, clinical support, and commercial support for the use of a product to each payor separately. This can be a time-consuming process, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance. For products administered under the supervision of a physician, obtaining coverage and adequate reimbursement may be particularly difficult because of the higher prices often associated with such drugs. Additionally, separate reimbursement for the product itself or the treatment or procedure in which the product is used may not be available, which may impact physician utilization.
In addition, third-party payors are increasingly reducing reimbursements for pharmaceutical products and services. The U.S. government and state legislatures have continued implementing cost-containment programs, including price controls, restrictions on coverage and reimbursement and requirements for substitution of generic products. Third-party payors are more and more challenging the prices charged, examining the medical necessity and reviewing the cost effectiveness of pharmaceutical products, in addition to questioning their safety and efficacy. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit sales of any product. Decreases in third-party reimbursement for any product or a decision by a third-party payor not to cover a product could reduce physician usage and patient demand for the product.
In international markets, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific products and therapies. For example, the European Union provides options for its member states to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. Pharmaceutical products may face competition from lower-priced products in foreign countries that have placed price controls on pharmaceutical products and may also compete with imported foreign products. Furthermore, there can be no assurance that a product will be considered medically reasonable and necessary for a specific indication or considered cost-effective by third-party payors in foreign or national-level systems. In the event that an adequate level of reimbursement is not established, then even if a product is approved by global regulatory authorities, it may adversely affect the ability of manufacturers to sell such product profitably.
Healthcare Reform
In the United States and certain foreign jurisdictions, there have been, and we expect there will continue to be, a number of legislative and regulatory changes to the healthcare system. In March 2010, the Affordable Care Act was signed into law, which substantially changed the way healthcare is financed by both governmental and private insurers in the United States. By way of example, the Affordable Care Act increased the minimum level of Medicaid rebates payable by manufacturers of brand name drugs from 15.1% to 23.1%; required collection of rebates for drugs paid by Medicaid managed care organizations; imposed a non-deductible annual fee on pharmaceutical manufacturers or importers who sell certain "branded prescription drugs" to specified federal government programs, implemented a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted, or injected; expanded eligibility criteria for Medicaid programs; creates a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research; and established a Center for Medicare Innovation at CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug spending.
Since its enactment, there have been judicial, executive branch and congressional challenges to certain aspects of the Affordable Care Act, and we expect there will be additional challenges and amendments to the Affordable Care Act in the future. By way of example, in 2017, Congress enacted the Tax Act, which eliminated the tax-based shared responsibility payment imposed by the Affordable Care Act on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the "individual mandate." On June 17, 2021. the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the Affordable Care Act is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. Thus, the Affordable Care Act will remain in effect in its current form. Further, prior to the U.S. Supreme Court ruling, on January 28, 2021, President Biden issued an executive order that initiated a special enrollment period for purposes of obtaining health insurance coverage through the Affordable Care Act marketplace. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the Affordable Care Act. It is possible that the Affordable Care Act will be subject to judicial or congressional challenges in the future. It is also unclear how other efforts to challenge, repeal or replace the Affordable Care Act will impact the Affordable Care Act.
Other legislative changes have been proposed and adopted since the Affordable Care Act was enacted, including aggregate reductions of Medicare payments to providers of 2% per fiscal year and reduced payments to several types of Medicare providers, which will remain in effect through 2031 absent additional congressional action, with the exception of a temporary suspension from May 1, 2020 through March 31, 2022. Under current legislation, the actual reduction in Medicare payments will vary from 1% in 2022 to up to 3% in the final fiscal year of this sequester.
Moreover, there has recently been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several congressional inquiries and proposed and enacted legislation designed, among other things, to bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs and reform government program reimbursement methodologies for pharmaceutical products. In July 2021, the Biden administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In
response to Biden’s executive order, on September 9, 2021, HHS released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue to advance these principles. No legislation or administrative actions have been finalized to implement these principles. In addition, Congress is considering drug pricing as part of other reform initiatives. In addition, individual states in the United States have also become increasingly active in implementing regulations designed to control pharmaceutical 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, mechanisms to encourage importation from other countries and bulk purchasing. Furthermore, there has been increased interest by third party payors and governmental authorities in reference pricing systems and publication of discounts and list prices.
Data Privacy and Security
Pharmaceutical manufacturers may be subject to U.S. federal and state and foreign health information privacy, security and data breach notification laws, which may govern the collection, use, disclosure and protection of health-related and other personal information. In the United States, HIPAA imposes privacy, security and breach reporting obligations with respect to individually identifiable health information upon "covered entities" (health plans, health care clearinghouses and certain health care providers), and their respective business associates, and their covered subcontractors that create, received, maintain or transmit protected health information in connection with providing a service for or on behalf of a covered entity. HIPAA mandates the reporting of certain breaches of health information to HHS, affected individuals and if the breach is large enough, the media. Entities that are found to be in violation of HIPAA as the result of a breach of unsecured protected health information, a complaint about privacy practices or an audit by HHS, may be subject to significant civil, criminal and administrative fines and penalties and/or additional reporting and oversight obligations if required to enter into a resolution agreement and corrective action plan with HHS to settle allegations of HIPAA non-compliance. Even when HIPAA does not apply, according to the Federal Trade Commission or the FTC, failing to take appropriate steps to keep consumers' personal information secure constitutes unfair acts or practices in or affecting commerce in violation of Section 5(a) of the Federal Trade Commission Act 15 U.S.C § 45(a). The FTC expects a company's data security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce vulnerabilities. Individually identifiable health information is considered sensitive data that merits stronger safeguards.
In addition, certain state laws govern the privacy and security of health information in certain circumstances, some of which are more stringent than HIPAA and many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts. Failure to comply with these laws, where applicable, can result in the imposition of significant civil and/or criminal penalties and private litigation. For example, the CCPA became effective on January 1, 2020, which, among other things, creates new data privacy obligations for covered companies and provides new privacy rights to California residents, including the right to opt out of certain disclosures of their information. The CCPA also creates a private right of action with statutory damages for certain data breaches, thereby potentially increasing risks associated with a data breach. Although the law includes limited exceptions, including for "protected health information" maintained by a covered entity or business associate, it may regulate or impact our processing of personal information depending on the context. Further, the CPRA was recently voted into law by California residents. The CPRA significantly amends the CCPA, and imposes additional data protection obligations on covered companies doing business in California, including additional consumer rights processes and opt outs for certain uses of sensitive data. It also creates a new California data protection agency specifically tasked to enforce the law, which would likely result in increased regulatory scrutiny of California businesses in the areas of data protection and security. The substantive requirements for businesses subject to the CPRA will go into effect on January 1, 2023, and become enforceable on July 1, 2023.
In Europe, the GDPR went into effect in May 2018, and imposes strict requirements for processing the personal data of data subjects within the European Economic Area and the United Kingdom. Companies that must comply with the GDPR face increased compliance obligations and risk, including more robust regulatory enforcement of data protection requirements and potential fines for noncompliance of up to €20 million or 4% of the annual global revenues of the noncompliant company, whichever is greater. Relatedly, following the United Kingdom's withdrawal from the European Economic Area and the European Union, and the expiry of the transition period, companies will have to comply with the GDPR and the GDPR as incorporated into United Kingdom national law, the latter regime having the ability to separately fine up to the greater of £17.5 million or 4% of global turnover. The relationship between the United Kingdom and the European Union in relation to certain aspects of data
protection law remains unclear, for example around how data can lawfully be transferred between each jurisdiction, which may expose us to further compliance risk.
Human Capital Resources
As of December 31, 2021, we had 71 full-time employees, who provide full time support to us, and 23 consultants who provide part time support to us. As of March 1, 2022, we had 39 full time employees and 14 part time consultants. None of our employees are represented by a labor union or covered by collective bargaining agreements and we consider our employee relations to be good. Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and additional employees. The principal purposes of our equity incentive plans are to attract, retain and motivate selected employees, consultants and directors through the granting of stock-based compensation awards and cash-based performance bonus awards.

Item 1A. Risk Factors
Investing in our common stock involves a high degree of risk. You should carefully consider the following risk factors, as well as the other information in this Annual Report on Form 10-K, including our consolidated financial statements and related notes, before deciding whether to invest in shares of our common stock. Many of the following risks and uncertainties are, and will be, exacerbated by the coronavirus disease 2019 (COVID-19) pandemic and any worsening of the global business and economic environment as a result. The occurrence of any of the adverse developments described in the following risk factors could materially and adversely harm our business, financial condition, results of operations or prospects. In that case, the trading price of our common stock could decline, and you may lose all or part of your investment.
Risks Relating to Our Financial Position and Need for Additional Capital
We are a clinical-stage biopharmaceutical company with no products approved for sale and we have not generated any product revenue to date, which makes it difficult to assess our future viability.
We are a clinical-stage biopharmaceutical company. Drug development is a highly speculative undertaking and involves a substantial degree of risk. We have not yet submitted any product candidates for approval or received approval of any product candidate by regulatory authorities in any jurisdiction, including the United States Food and Drug Administration (FDA). We do not expect to generate revenue from product sales unless we, or we or our collaborators, obtain approval and commercialize our product candidates, which we do not expect to occur for
several years, if ever. We expect to continue to incur net losses for the foreseeable future, and we expect our expenses and operating losses to increase substantially as we advance ANG-3070 and our other product candidates through clinical and preclinical development, seek regulatory approval for ANG-3070 or any of our other product candidates, and continue to incur expenses to protect our intellectual property, maintain our general and administrative support functions, including hiring additional personnel, and incur costs associated with operating as a public company.
In addition, while we have a license agreement with Vifor Pharma relating to ANG-3777 that contemplates upfront, regulatory and commercial milestone payments as well as royalties on sales of ANG-3777, we do not intend to continue the clinical development plan for ANG-3777 set forth in the Vifor License , which had included a Phase 3 study for CSA-AKI and a Phase 4 confirmatory study in DGF. Thus, it is unlikely we will receive any substantial revenue stream from milestone or royalty payments under the license agreement.
If we are unable to enroll our clinical trials for ANG-3070 or if ANG-3070 or any of our other product candidates fail in ongoing clinical trials or do not gain regulatory approval, we may never generate revenue or become profitable.
To achieve our goals we will require substantial additional funding, for which capital may not be available to us on acceptable terms, or at all, and, if not so available, may require us to delay, limit, reduce or cease our clinical trials or operations.
We have invested and will continue to invest a significant portion of our efforts and financial resources in research and development activities. We are currently in the process of advancing ANG-3070 through a Phase 2 dose-finding clinical trial in 100 patients with Primary Proteinuria Kidney Diseases (PPKDs), specifically FSGS and IgAN patients, in the United States, Georgia, Bulgaria, Lithuania, Spain and Australia, and other product candidates through preclinical and potential clinical development. Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is expensive. We will require substantial additional future capital to complete clinical development, including additional clinical studies, and seek regulatory approval for ANG-3070 for any indication as well as to conduct the research, clinical and regulatory activities necessary to bring our other product candidates to market. Regulatory authorities in the United States and elsewhere could also require that we perform additional preclinical studies or clinical trials to receive or maintain regulatory approval of our product candidates, including ANG-3070, and our expenses would further increase beyond what we currently expect. Because successful development of our product candidates is uncertain, we are unable to estimate the actual funds we will require to complete research and development of such product candidates as well as the costs of commercializing any of our wholly-owned product candidates and those for which we retain the right to commercialize.
We estimate our current cash and cash equivalents will be sufficient to fund our operating expenses and capital expenditure requirements well into 2023. We have based our projections of operating capital requirements on assumptions that may prove to be incorrect and we may use all our available capital resources sooner than we expect. Because of the numerous risks and uncertainties associated with research, development and commercialization of biotechnology products, we are unable to estimate the exact amount of our operating capital requirements. The amount and timing of our future funding requirements will depend on many factors, including, but not limited to:
▪the scope, progress, results and costs of researching and developing ANG-3070 or other product candidates, and conducting preclinical studies and clinical trials;
▪the outcome of our ongoing and future clinical trials, including our ANG-3070 Phase 2 clinical trial in PPKD;
▪whether we are able to take advantage of any FDA expedited development and approval programs for any of our product candidates;
▪the extent to which COVID-19 may impact our business, including our clinical trials and financial condition;
▪the willingness of the FDA and foreign regulatory authorities to accept the results of our ongoing ANG-3070 Phase 2 clinical trial, as well as our other completed and planned clinical trials and preclinical studies and other work;
▪the number and characteristics of product candidates that we pursue, including our product candidates in preclinical development;
▪the ability of our product candidates to progress through clinical development successfully;
▪our need to expand our research and development activities, including to conduct additional clinical trials;
▪the costs of acquiring, licensing or investing in businesses, products, product candidates and technologies;
▪our ability to maintain, expand and defend the scope of our intellectual property portfolio, including the amount and timing of any payments we may be required to make, or that we may receive, in connection with the licensing, filing, prosecution, defense and enforcement of any patents or other intellectual property rights;
▪our need and ability to hire additional personnel, including management, clinical development, medical and commercial personnel;
▪the costs associated with being a public company, including our need to implement additional internal systems and infrastructure, including financial and reporting systems;
▪the costs associated with securing and establishing manufacturing capabilities, as well as those associated with packaging, warehousing and distribution; and
▪the economic and other terms, timing of and success of our existing licensing arrangements and any collaboration, licensing or other arrangements into which we may enter in the future and the timing and amount of payments thereunder.
Until such time we can generate sufficient revenue from sales of ANG-3070 or any other product candidate, if ever, we expect to finance our operations through public or private equity offerings, debt financings or other sources of capital, including collaborations, licenses, credit or loan facilities, receipt of research contributions or grants, tax credits or a combination of one or more of these funding sources. Adequate funding may not be available to us on acceptable terms, or at all. This may be particularly true if global capital markets continue to experience extreme volatility due to the COVID-19 pandemic or armed conflict. To the extent we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be or could be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing and 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 or declaring dividends. If we raise funds through additional collaborations, or other similar arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us and/or may reduce the value of our common stock. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or commercialization efforts or grant rights to develop and market our product candidates even if we would otherwise prefer to develop and market such product candidates ourselves.
Risks Relating to the Development and Regulatory Approval of Our Product Candidates
COVID-19 could adversely impact our business, including our clinical trials and financial condition.
We have been and continue to be subject to risks related to public health crises such as the global pandemic associated with COVID-19. As COVID-19 continues to persist around the globe, we may continue to experience disruptions that could severely impact our business and clinical trials, including:
▪delays or difficulties in enrolling patients in our clinical trials, including our ANG-3070 Phase 2 study in PPKD with clinical sites in Eastern Europe, namely Georgia, Lithuania and Bulgaria;
▪delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff;
▪diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials;
▪interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers and others or interruption of clinical trial subject visits and study procedures, the occurrence of which could affect the integrity of clinical trial data;
▪risk that participants enrolled in our clinical trials will acquire COVID-19 while the clinical trial is ongoing, which could impact the results of the clinical trial, including by increasing the number of observed adverse events;
▪limitations in employee resources that would otherwise be focused on the conduct of our clinical trials, including because of sickness of employees or their families or the desire of employees to avoid contact with large groups of people;
▪delays in receiving authorizations from local regulatory authorities to initiate our planned clinical trials;
▪delays in clinical sites receiving the supplies and materials needed to conduct our clinical trials;
▪interruption in global shipping that may affect the transport of clinical trial materials, such as investigational drug product used in our clinical trials;
▪changes in local regulations as part of a response to the COVID-19 pandemic which may require us to change the ways in which our clinical trials are conducted, which may result in unexpected costs, or to discontinue the clinical trials altogether;
▪interruptions or delays in preclinical studies due to restricted or limited operations at our research and development laboratory facilities;
▪delays in necessary interactions with local regulators, ethics committees and other important agencies and contractors due to limitations in employee resources or forced furlough of government employees; and refusal of the FDA to accept data from clinical trials in affected geographies outside the United States.
We are continuing to evaluate the impact of the COVID-19 restrictions on our expected pace of enrollment, as such impacts could delay the timing of topline results in our ongoing clinical trials.
The global pandemic of COVID-19 continues to evolve. The extent to which COVID-19 may impact our business, including our clinical trials, and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the geographic spread of the disease and its variants, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease.
Product development and regulatory approval involve a lengthy and expensive process with uncertain outcomes. We cannot be certain ANG-3070 or any of our other product candidates will receive or maintain regulatory approval and, without regulatory approval, we and our collaborators will not be able to market our product candidates.
We currently have no products approved for sale, and we cannot guarantee we will ever have approved products that we or our collaborators can market and sell. The development of a product candidate and issues relating to its approval and marketing are subject to extensive regulation by regulatory authorities, including the FDA in the United States and other regulatory authorities in other foreign countries, with regulations differing from country to country. We are not permitted to market our product candidates in the United States or elsewhere until we receive regulatory approval and/or marketing authorization, such as approval of an NDA from the FDA. We have not submitted any marketing applications for any of our product candidates.
New drug marketing applications must include extensive preclinical and clinical data and supporting information to establish the product candidate's safety and effectiveness for each desired indication. Such marketing applications must also include significant information regarding the chemistry, manufacturing, and controls for the product. Obtaining approval of our product candidates will be a lengthy, expensive, and uncertain process, and we may not be successful. Specifically, the review processes of the FDA and foreign regulatory authorities can take years to complete, and approval is never guaranteed. Even if a product is approved, the FDA or foreign regulatory authorities may limit the indications for which the product may be marketed, require extensive warnings on the product labeling or require expensive and time-consuming additional clinical trials or reporting as conditions of approval. The FDA or foreign regulatory authorities also may not approve our product candidates with the labeling that we believe is necessary or desirable for the successful commercialization of such product candidates. Obtaining regulatory approval for marketing of a product candidate in one country does not ensure we will be able to obtain regulatory approval in any other country.
The FDA or any foreign regulatory authorities can delay, limit or deny approval of our product candidates for many reasons, including:
▪our inability to demonstrate to the satisfaction of the FDA or the applicable foreign regulatory authority that any of our product candidates are safe and effective for the requested indication;
▪the FDA's or the applicable foreign regulatory authority's disagreement with our trial protocols or the interpretation of data from preclinical studies or clinical trials;
▪our inability to demonstrate that the clinical and other benefits of any of our product candidates outweigh any safety or other perceived risks;
▪the FDA's or the applicable foreign regulatory authority's requirement for additional preclinical studies or clinical trials;
▪the FDA's or the applicable foreign regulatory authority's non-approval of the formulation, labeling or specifications of any of our product candidates;
▪the FDA's or the applicable foreign regulatory authority's failure to approve our manufacturing processes and facilities or the facilities of third-party manufacturers upon which we rely; or
▪the potential for approval policies or regulations of the FDA or the applicable foreign regulatory authorities to significantly change in a manner rendering our clinical data insufficient for approval.
We cannot predict whether our ongoing or future clinical trials of our product candidates will be successful, or whether regulators will agree with our conclusions regarding the preclinical studies and clinical trials we have conducted to date or that we conduct in the future. Accordingly, we may never receive approval of ANG-3070 or any of our other product candidates, or be authorized to market and sell our product candidates to customers. If we are unable to obtain approval from regulatory authorities for ANG-3070 or any of our other product candidates, we may not be able to generate sufficient revenue to become profitable or to continue our operations.
Delays or difficulties in the commencement, enrollment and completion of clinical trials could result in increased costs to us and delay or limit our ability to obtain regulatory approval for ANG-3070 and our other product candidates.
Delays in the commencement, enrollment, and completion of clinical trials could increase our product development costs or limit the regulatory approval of our product candidates. We are currently enrolling patients in our Phase 2 clinical trial of ANG-3070 for PPKD. Delays in any of our clinical trials may increase the amount of additional funding we will require to complete these trials. The commencement, enrollment, and completion of clinical trials can be delayed, challenged or suspended for a variety of reasons, including but not limited to:
▪severity of the disease under investigation;
▪inability to obtain sufficient funds required for a clinical trial;
▪inability to obtain Institutional Review Board (IRB) approval at participating institutions;
▪our ability to effectively manage the clinical research organizations (CROs) we have engaged to conduct of our clinical trials;
▪the extent to which COVID-19 may impact our clinical trials and our or our CROs' ability to monitor such trials;
▪the extent to which the Russian invasion of Ukraine may impact our clinical trials and our or our CROs' ability to monitor such trials;
▪availability and efficacy of approved medications or competing product candidates in development for the disease under investigation;
▪the patient eligibility criteria defined in the protocol;
▪the ability to attract and retain patients and the general willingness of patients to enroll, consent and complete participation in the trial;
▪the extent to which there is competition for patients to enroll in clinical trials;
▪the size of the patient population required for analysis of the trial's primary endpoint or endpoints;
▪clinical holds, other regulatory objections to commencing or continuing a clinical trial, or the inability to obtain regulatory approval to commence a clinical trial in countries requiring such approvals;
▪discussions with the FDA or foreign regulatory authorities regarding the scope or design of our clinical trials;
▪severe or unexpected drug-related adverse effects experienced by patients; and
▪inability to timely manufacture sufficient quantities of the product candidate and other clinical supplies required for a clinical trial.
Changes in regulatory requirements and related guidance related to regulatory approval may also occur and we may need to amend clinical trial protocols to reflect these changes. Amendments may require us to resubmit clinical trial protocols to IRBs for re-examination, which may impact the costs, timing or successful completion of our clinical trials.
Furthermore, if we are required to conduct additional clinical trials or other preclinical studies of our product candidates beyond those contemplated, our ability to obtain or maintain regulatory approval of these product candidates and generate revenue from their sales would be similarly harmed.
Clinical failure can occur at any stage of clinical development, and the results of earlier clinical trials are not necessarily predictive of future results.
Clinical failure can occur at any stage of our clinical development. For example, in the fourth quarter of 2021, we disclosed the results of the ANG-3777 Phase 3 clinical trial for delayed graft function (DGF) and AKI associated with cardiac surgery involving cardiopulmonary bypass (CSA-AKI), neither of which met their primary endpoints despite the existence of encouraging pre-clinical and clinical data for ANG-3777 established prior to initiating such studies. Clinical trials may produce negative or inconclusive results, and we or our collaborators may decide, or regulators may require us, to conduct additional clinical trials or preclinical studies. In addition, data obtained from trials and studies are susceptible to various interpretations, and regulators may not interpret our data as favorably as we do, which may delay, limit or prevent regulatory approval. Success in preclinical studies and early clinical trials does not ensure subsequent clinical trials will generate the same or similar results or otherwise provide adequate data to demonstrate the efficacy and safety of a product candidate. A number of companies in the pharmaceutical industry, including those with greater resources and experience than us, have suffered significant setbacks in Phase 3 registration trials, even after seeing promising results in earlier clinical trials.
In addition, the design of a clinical trial can determine whether its results will support approval of a product, and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced. We have limited experience in designing clinical trials as we have never previously completed a Phase 3 registration trial with results sufficient to obtain regulatory approval or submitted an NDA to the FDA or a marketing application to any foreign regulatory authority, and we may be unable to design and execute a clinical trial to support regulatory approval. Further, clinical trials of potential products often reveal it is not practical or feasible to continue development efforts.
Furthermore, our ability to show statistical significance in our clinical trials may be affected by factors beyond our control. This could result in the need for additional clinical trials prior to submission of an NDA to the FDA or other marketing applications to foreign regulatory authorities.
There can also be significant variability in safety and/or efficacy results between different trials of the same product candidate due to numerous factors, including changes in trial protocols, differences in composition of the patient populations, adherence to the dosing regimen and other trial protocols, differences in drug lot manufacturing, and the rate of dropout among clinical trial participants. We do not know whether any preclinical or clinical trials we or any of our existing or future collaborators may conduct will demonstrate consistent or adequate efficacy and safety to obtain regulatory approval to market our product candidates.
If ANG-3070 or our other product candidates are the subject of clinical trial failures or are found to be unsafe or lack efficacy, we will not be able to obtain regulatory approval for them and our business would be harmed.
Our clinical trials could be disrupted by the uncertainty of war due to the aggressive actions taken by Russia which, if this occurs, could delay our ability to complete our clinical trials.
We are currently in the process of advancing ANG-3070 through a Phase 2 clinical trial in 100 patients with Primary Proteinuria Kidney Diseases (PPKD), specifically FSGS and IgAN patients, including trial sites in Georgia, Bulgaria and Lithuania. In late February 2022, Russia initiated significant military action against Ukraine, and given the proximity of Georgia, Bulgaria and Lithuania to Russia there may be significant uncertainty and unrest in these countries which could impair or delay the progress of our clinical trials in those countries. Further, in response to the Russian invasion of Ukraine, the U.S. and certain other countries imposed significant sanctions and trade actions against Russia, and the U.S. and certain other countries could impose further sanctions, trade restrictions and other retaliatory actions should the conflict continue or worsen. It is not possible to predict the broader consequences of the conflict, including related geopolitical tensions, and the measures and retaliatory actions taken by the U.S. and other countries in respect thereof, as well as any counter measures or retaliatory actions by Russia in response, is likely to cause regional instability, geopolitical shifts and could materially adversely affect global trade, currency exchange rates, regional economies and the global economy. In particular, while it is difficult to anticipate the impact of any of the foregoing on our clinical trials or our business, the conflict and actions taken in response to the conflict could increase our costs, disrupt our supply chain, impair the progress of our clinical trials, impair our ability to raise
additional capital when needed on acceptable terms, if at all, or otherwise adversely affect our business, financial condition and results of operations.
Even if we successfully complete ongoing and planned clinical trials of one or more of our product candidates, the product candidates may fail for other reasons.
Even if we successfully complete the clinical trials for one or more of our product candidates, such product candidates may fail for other reasons, including the possibility the product candidates will:
▪fail to receive the regulatory approvals required to market them as drugs;
▪be subject to proprietary rights held by others requiring the negotiation of a license agreement prior to marketing;
▪be difficult or expensive to manufacture on a commercial scale;
▪have adverse side effects that make their use less desirable;
▪not achieve reimbursement or sales levels sufficient for continued marketing; or
▪fail to compete with product candidates or other treatments commercialized by our competitors.
If we are unable to receive and maintain the required regulatory approvals, secure our intellectual property rights, maintain an acceptable safety profile or fail to compete with our competitors' products, our business, financial condition, and results of operations could be materially and adversely affected.
Our product candidates may have undesirable side effects which may delay or halt clinical development or prevent marketing approval or, if approval is received, require them to be taken off the market, require them to include safety warnings, or otherwise limit their sales.
The results of our clinical trials of our product candidates may show that such product candidates led to patient safety concerns or undesirable or unacceptable side effects, creating risk to the patient which is deemed to outweigh the potential benefits of treatment to that patient. Unforeseen side effects from any of our product candidates could arise either during clinical development or, if approved, after the approved product has been marketed. Any such event could interrupt, delay or halt such clinical trials, resulting in the denial of regulatory approval by the FDA and other regulatory authorities or result in restrictive label warnings, if approved. In light of widely publicized events concerning the safety risk of certain drug products, regulatory authorities, members of Congress, the Government Accounting Office, medical professionals and the general public have raised concerns about potential drug safety issues. These events have resulted in the withdrawal of drug products, revisions to drug labeling that further limit use of the drug products and establishment of risk management programs that may, for instance, restrict distribution of drug products. The increased attention to drug safety issues may result in a more cautious approach by the FDA to clinical trials. Data from clinical trials may receive greater scrutiny with respect to safety, which may make the FDA or other regulatory authorities more likely to terminate clinical trials before completion, or require longer or additional clinical trials that may result in substantial additional expense and a delay or failure in obtaining approval or approval for a more limited indication than originally sought.
ANG-3070 is a tyrosine kinase inhibitor (TKI). TKIs are widely used across a range of indications. Depending on their specific targets, TKIs have been associated with several near and long-term side effects. They have been most extensively used in cancer where cardiopulmonary toxicity, myelosuppression, and gastrointestinal toxicity have been key side effects in addition to several others. TKIs have also been studied in fibrosis, with nintedanib being approved for IPF. Nintedanib has been associated with several side effects including severe liver injuries, arterial thromboembolic events and gastrointestinal disorders including diarrhea, nausea and vomiting, and risk of bleeding. Pirfenidone, with an unknown mechanism of action, has also been approved in IPF and has been associated with elevated liver enzymes, diarrhea, nausea vomiting, photosensitivity and rash.
While we believe the preliminary safety and pharmacokinetic data from our Phase 1 healthy-volunteer study in Australia support the conduct of our ongoing Phase 2 clinical trial in PPKD and additional clinical trials, there can be no assurance similar or unforeseen side effects will not occur during such clinical trial. The range and potential severity of possible side effects from systemic therapies is significant.
If any of our product candidates receives marketing approval and we or others later identify undesirable or unacceptable side effects caused by such products:
▪regulatory authorities may require the addition of labeling statements or specific warnings, including "Black Box" warnings if the FDA views the possible side effects as very severe;
▪we may be required to change instructions regarding the way the product is administered, conduct additional clinical trials, or change the labeling of the product;
▪we may be subject to limitations on how we may promote the product;
▪sales of the product may decrease significantly;
▪regulatory authorities may require us to take our approved product off the market;
▪we may be subject to litigation or product liability claims; and
▪our reputation may suffer.
Any of these events could prevent us or any potential future collaborators from achieving or maintaining market acceptance of the affected product or could substantially increase commercialization costs and expenses, which, in turn, could delay or prevent us from generating significant revenues from the sale of our products.
Clinical trials of our product candidates may not uncover all possible adverse effects patients may experience or be indicative of the effect of our product candidates post approval in the general population.
Clinical trials are conducted in representative samples of the potential patient population, which may have significant variability. By design, clinical trials are based on a limited number of subjects and are of limited duration of exposure to the product, to determine whether the product candidate demonstrates the substantial evidence of efficacy and safety necessary to obtain regulatory approval. As with the results of any statistical sampling, we cannot be sure that any evidence of efficacy will be repeated in the general population or all side effects of our product candidates may be uncovered. It may be the case that only with a significantly larger number of patients exposed to the product candidate for a longer duration may a more complete safety and efficacy profile be identified Further, even larger clinical trials may not identify rare serious adverse events, and the duration of such studies may not be sufficient to identify when those events may occur particularly for adverse events or safety risks that could occur over time, such as the development and diagnosis of cancer. Other products have been approved by the regulatory authorities for which safety concerns have been uncovered following approval. Such safety concerns have led to labeling changes, restrictions on distribution through use of a REMS, or withdrawal of products from the market, and any of our product candidates may be subject to similar risks.
Patients treated with our products, if approved, may experience previously unreported adverse reactions, and it is possible that the FDA or other regulatory authorities may ask for additional safety data as a condition of, or in connection with, our efforts to obtain approval of our product candidates. If safety problems occur or are identified after our products, if any, reach the market, we may make the decision or be required by regulatory authorities to amend the labeling of our products, recall our products, or even withdraw approval for our products.
Due to the significant resources required for the development and commercialization of our product candidates, we must prioritize development of certain product candidates and/or certain disease indications. We may expend our limited resources on product candidates or indications that do not yield a successful product and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.
We plan to develop a pipeline of product candidates to treat potentially life-threatening acute organ injuries and fibrotic diseases. However, due to the significant resources required for the development of our product candidates, we must focus on specific indications and decide which product candidates to pursue and the amount of resources to allocate to each. For instance, in 2022, we plan to identify a lead candidate in one or more of our pre-clinical programs, but not in all such programs. Our primary focus is on advancing ANG-3070 in PPKD through our ongoing Phase 2 dose-finding study in that population and filing an IND to support the clinical development of ANG-3070 in IPF.
Our decisions concerning the allocation of research, development, collaboration, management and financial resources toward particular product candidates or therapeutic areas may not lead to the development of any viable commercial product and may divert resources away from better opportunities. Similarly, our potential decisions to delay, terminate or collaborate with third parties in respect of certain programs may subsequently also prove to be suboptimal and could cause us to miss valuable opportunities. If we make incorrect determinations regarding the viability or market potential of any of our programs or product candidates or misread trends in the biopharmaceutical industry, our business, financial condition and results of operations could be materially adversely affected. As a result, we may fail to capitalize on viable commercial products or profitable market opportunities, be required to
forego or delay pursuit of opportunities with other product candidates or other diseases that may later prove to have greater commercial potential than those we choose to pursue, or relinquish valuable rights to such product candidates through collaboration, licensing or other royalty arrangements in cases in which it would have been advantageous for us to invest additional resources to retain development and commercialization rights.
Our business operations and current and future relationships with investigators, healthcare professionals, consultants, third-party payors, patient organizations and customers will be subject to applicable healthcare regulatory laws, which could expose us to penalties.
Our business operations and current and future arrangements with investigators, healthcare professionals, consultants, third-party payors, patient organizations and customers, may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations. These laws may constrain the business or financial arrangements and relationships through which we conduct our operations, including how we research, market, sell and distribute our product candidates, if approved. Such laws include: the U.S. federal Anti-Kickback Statute; U.S. federal civil and criminal false claims laws, including the civil False Claims Act; the federal fraud provision of the U.S. federal Health Insurance Portability and Accountability Act of 1996 (HIPAA); HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH; the FDCA; the U.S. Physician Payments Sunshine Act; federal consumer protection and unfair competition laws; analogous U.S. state laws and regulations, including state anti-kickback and false claims laws; and similar healthcare laws and regulations in the EU and other jurisdictions, including reporting requirements detailing interactions with and payments to healthcare providers.
Ensuring that our current internal operations and future business arrangements with third parties comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices, including our relationships with physicians and other healthcare providers, some of whom are compensated in the form of stock options for consulting services provided, may not comply with current or future statutes, regulations, agency guidance or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of the laws described above or any other governmental laws and regulations that may apply to us, we may be subject to significant penalties, including civil, criminal and administrative penalties, damages, fines, exclusion from government-funded healthcare programs, such as Medicare and Medicaid or similar programs in other countries or jurisdictions, integrity oversight and reporting obligations to resolve allegations of non-compliance, disgorgement, individual imprisonment, contractual damages, reputational harm, diminished profits and the curtailment or restructuring of our operations. If any of the physicians or other providers or entities with whom we expect to do business are found to not be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs and imprisonment, which could affect our ability to operate our business. Further, defending against any such actions can be costly, time-consuming and may require significant personnel resources. Therefore, even if we are successful in defending against any such actions that may be brought against us, our business and our ability to sell our products may be materially harmed.
Recently enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval for and commercialize our product candidates and affect the prices we may obtain.
In the United States and some 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.
In the United States, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act (Affordable Care Act), was intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms.
Since its enactment, there have been judicial, executive branch and congressional challenges to certain aspects of the Affordable Care Act, and we expect there will be additional challenges and amendments to the Affordable Care Act in the future. For example, legislation informally titled the Tax Cuts and Jobs Acts (TCJA) was enacted, which, among other things, removed penalties for not complying with the individual mandate to carry health insurance. On June 17, 2021 the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the Affordable Care Act is unconstitutional in its entirety because the “individual mandate” was repealed by
Congress. Thus, the Affordable Care Act will remain in effect in its current form. It is possible that the Affordable Care Act will be subject to judicial or congressional challenges in the future. It is unclear how such challenges or the health reform measures of the Biden administration will affect the Affordable Care Act or our business.
In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted. In August 2011, the Budget Control Act of 2011, among other things, included aggregate reductions of Medicare payments to providers of 2% per fiscal year, which went into effect on April 1, 2013 and, due to subsequent legislative amendments, will remain in effect through 2031, with the exception of a temporary suspension from May 1, 2020 through March 31, 2022, unless additional congressional action is taken. Under current legislation, the actual reduction in Medicare payments will vary from 1% in 2022 to up to 3% in the final fiscal year of this sequester. In addition, on January 2, 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things, reduced Medicare payments to several providers, including hospitals, and an increase in the statute of limitations period for the government to recover overpayments to providers from three to five years. These new laws may result in additional reductions in Medicare and other healthcare funding and otherwise affect the prices we may obtain.
We expect that other healthcare reform measures that may be adopted in the future may result in additional reductions in Medicare and other healthcare funding, more rigorous coverage criteria, new payment methodologies and in additional downward pressure on the price that we receive for any approved product. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our product candidates, if approved.
Moreover, there has recently been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products. In July 2021, the Biden administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, HHS released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue to advance these principles. No legislation or administrative actions have been finalized to implement these principles. In addition, Congress is considering drug pricing as part of other reform initiatives. Individual states in the United States have become increasingly aggressive in implementing regulations designed to contain pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures. Legally mandated price controls on payment amounts by third-party payors or other restrictions could harm our business, results of operations, financial condition and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for our product candidates, if approved, or put pressure on our product pricing, which could negatively affect our business, results of operations, financial condition and prospects.
Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products. We cannot be sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any, may be. In addition, increased scrutiny by Congress of the FDA's approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements.
We rely on single-source third party contract manufacturing organizations to manufacture and supply our product candidates, and if the FDA or foreign regulatory authorities do not approve these manufacturing facilities or if these organizations fail to perform, our ability to conduct clinical trials and obtain regulatory approval our product candidates may be harmed.
We do not own facilities for clinical and commercial manufacturing of our product candidates, including ANG-3070, and we rely upon third-party contract manufacturing organizations to manufacture and supply product candidates for our clinical trials and we will rely in such manufacturers to meet commercial demand. Currently, we rely on and have agreements with a single third-party contract manufacturer to supply the drug substance for ANG-3070 and to manufacture all clinical trial supplies of ANG-3070.
Additionally, the facilities at which ANG-3070 or any of our other product candidates are manufactured must be the subject of a satisfactory inspection before the FDA or the regulators in other jurisdictions approve the product candidate manufactured at that facility. We are completely dependent our third-party vendors for compliance with the current Good Manufacturing Practice requirements (cGMPs). requirements of United States and non-United States regulators for the manufacture of our active ingredients, drug products, and finished products. If our manufacturers cannot successfully manufacture material conforming to our specifications and cGMPs of any applicable governmental agency, our product candidates will not be approved or, if already approved, may be subject to recalls or demands by regulatory agencies to stop selling the product until manufacturing issues are resolved.
Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured the product candidates, including:
▪the possibility we are unable to enter into a manufacturing agreement with a third party to manufacture our product candidates;
▪the possible breach of the manufacturing agreements by the third parties because of factors beyond our control; and
▪the possibility of termination or nonrenewal of the agreements by the third parties before we are able to arrange for a qualified replacement third-party manufacturer.
Any of these factors could delay the development or approval of our product candidates, cause us to incur higher costs or prevent us from developing our product candidates successfully. Furthermore, if the supply chain for our clinical trial materials is interrupted or if any of our contract manufacturers fail to deliver the required clinical trial supplies on a timely basis and at commercially reasonable prices and we are unable to find one or more replacement manufacturers capable of production at a substantially equivalent cost, in substantially equivalent volumes and quality and on a timely basis, we may be unable to supply our clinical trial programs with clinical trial materials which could delay our programs and increase our costs. For instance, we are conducting our ongoing Phase 2 of ANG-3070 in certain countries in Eastern Europe, namely Georgia, Bulgaria, and Lithuania. If our supply chain in the region is interrupted for any reason, including the current war in Ukraine, the dosing of patients in our Phase 2 clinical trial could be slowed, delayed or stopped. Further, such challenges could be compounded by the COVID-19 pandemic.
Changes in structure of or funding for the FDA and other government agencies could hinder their ability to hire and retain key leadership and other personnel, or otherwise prevent new products and services from being developed in a timely manner, which could negatively impact our business.
The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel, the maintenance of regulatory review timelines, and statutory, regulatory, and policy changes. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable. The lack of appropriate funding or appropriate resource for the FDA, could have material adverse effect on our ability to develop ANG-3070 and our product candidates.
We have and may continue to conduct future clinical trials outside of the United States. The FDA and other regulatory authorities may not accept data from such trials, in which case our development plans will be delayed, which could materially harm our business.
We are enrolling or plan to enroll patients in our Phase 2 clinical trial of ANG-3070 for PPKD in Georgia, Australia, Lithuania, Bulgaria, Spain, Italy and potentially other jurisdictions under separate clinical trial applications in such jurisdictions. Although the FDA may accept data from clinical trials conducted outside the United States, acceptance of this data is subject to certain conditions imposed by the FDA. For example, the FDA requires the clinical trial to have been conducted in accordance with GCPs, and the FDA must be able to validate the data from the clinical trial through an onsite inspection if it deems such inspection necessary. In addition, when clinical trials are conducted only at sites outside of the United States, such trials may not be subject to IND review, meaning the FDA may not provide advance comment on the clinical protocols for the trials, and therefore there is an additional potential risk that the FDA could determine that the study design or protocol for a non-U.S. clinical trial was inadequate, which would likely require additional clinical trials in order to seek FDA approval. If the FDA does not
accept data from our clinical trials of ANG-3070 and any future product candidates conducted outside the United States, it would likely result in the need for additional clinical trials, which would be costly and time consuming and delay or permanently halt our development of ANG-3070 and any future product candidates.
Conducting clinical trials outside the United States also exposes us to additional risks, including risks associated with:
▪additional foreign regulatory requirements;
▪foreign exchange fluctuations;
▪patient monitoring and compliance;
▪compliance with foreign manufacturing, customs, shipment and storage requirements;
▪cultural differences in medical practice and clinical research;
▪diminished protection of intellectual property in some countries, and
▪operational risks resulting from war and conflict certain countries or in proximity to the countries in which we are conducting our clinical trials.
If manufacturers obtain approval for generic versions of our products or product candidates, our business will be materially harmed.
In our industry, much of an innovative product's commercial value is realized while it has patent protections and market exclusivity. When market exclusivity expires generic versions of the product can be approved and marketed, and there can be substantial decline in the innovative product's sales.
Market exclusivity for our products is based upon patent rights and certain regulatory forms of exclusivity. If we are unable to secure or maintain our exclusivities, we may face generic competition that could materially impede our ability to effectively commercialize our products, including be reducing the price we can charge and reducing our market share. ANG-3070 and our other product candidates are protected by a number of granted and pending patent applications, and may be entitled to certain regulatory exclusivities if approved.
In some countries, patent protections for our products may not exist because certain countries did not historically offer the right to obtain specific types of patents or we did not file patents in those markets. Also, the patent environment is unpredictable and the validity and enforceability of patents cannot be predicted with certainty.
Specifically, with regard to the potential for generic entry in the United States, under the U.S. Food, Drug and Cosmetic Act (FDCA) the FDA can approve an Abbreviated New Drug Application (ANDA) for a generic version of an approved branded drug without the ANDA applicant undertaking the clinical testing necessary to obtain approval to market a new drug. Generally, in place of such clinical studies, an ANDA applicant needs only to submit data demonstrating that its product has the same active ingredient(s), strength, dosage form, route of administration and that it is bioequivalent to the approved product.
The FDCA requires that an ANDA applicant certify either that its generic product does not infringe any of the patents listed by the owner of the branded drug in the Orange Book or that those patents are not enforceable. This process is known as a paragraph IV certification. Upon notice of a paragraph IV certification, a patent owner or NDA holder has 45 days to bring a patent infringement suit in federal district court against the company seeking ANDA approval of a product covered by one of the owner's patents. If this type of suit is commenced, the FDCA provides a 30-month stay on the FDA's approval of the competitor's application. If the litigation is resolved in favor of the ANDA applicant or the challenged patent expires during the 30-month stay period, the stay is lifted and the FDA may thereafter approve the application based on the standards for approval of ANDAs. Once an ANDA is approved by the FDA, the generic manufacturer may market and sell the generic form of the branded drug in competition with the branded medicine.
The ANDA process can result in generic competition if the patents at issue are not upheld or if the generic competitor is found not to infringe the owner's patents. If this were to occur with respect to any of our product candidates after approval, our business could be materially harmed.
Risks Relating to Collaborations and Commercialization of Our Product Candidates
If we are able to develop and obtain regulatory approval for any of our product candidates, our business will be materially harmed if we are unable to successfully commercialize such approved products.
Even if we receive regulatory approval of any product candidate, including ANG-3070, it is uncertain whether we will be able to successfully commercialize such product. Our marketing of any approved product will be limited to the product’s approved use and potentially subject to other limitations as set forth in its approved prescribing information and package insert. Accordingly, we cannot ensure any of our future approved products will be successfully developed, approved or commercialized. If we are unable to successfully commercialize our future approved products, we may not be able to generate sufficient revenue to operate our business. In particular, the future commercial success of any approved product is subject to a number of risks, including the following:
▪the emergence of unknown side effects causing an approved drug to be taken off the market;
▪the receipt of market acceptance by physicians, hospitals, payers and patients;
▪our ability to obtain meaningful pricing and reimbursement for any approved product, and
▪our ability to obtain, maintain or enforce our patents and other intellectual property rights related to our approved products.
Our existing collaborations as well as additional collaboration arrangements we may enter into in the future may not be successful, which could adversely affect our ability to develop and commercialize our product candidates.
We have licensed certain rights with respect to ANG-3777 to Vifor Pharma, and in the future we may seek additional collaboration arrangements for the commercialization, or potentially for the development, of certain of our product candidates depending on the merits of retaining development and/or commercialization rights for ourselves as compared to entering into collaboration arrangements.
The success of our existing and any future collaboration arrangements, will depend heavily our ability with our collaborators to develop and obtain approval of the any licensed product or product candidate and on the efforts and activities of our collaborators. For instance, in November 2020, we entered into a license agreement (the Vifor License) with Vifor International, Ltd. (Vifor Pharma), granting Vifor Pharma global rights (excluding Greater China) to develop, manufacture and commercialize ANG-3777 in all therapeutic, prophylactic and diagnostic uses for renal indications and congestive heart failure. Pursuant to the Vifor License, we are eligible to receive certain clinical, post-approval, or sales milestone payments, and/or royalties, based upon the clinical development plan for ANG-3777 set forth in Vifor License. However, we do not expect to receive any such payments as we do not intend to continue to pursue the clinical development plan for ANG-3777 set forth in the Vifor License, which had included a Phase 3 study for CSA-AKI and a Phase 4 confirmatory study in DGF, for ANG-3777 based upon clinical trial results for ANG-3777 disclosed in the fourth quarter of 2021.
Further, our dependence on collaborative arrangements subjects us to a number of risks, including the risk we may never receive substantial economic benefit from the arrangements, we may not be able to control the amount and timing of resources our collaborators may devote to the product candidates; our collaborators may experience financial difficulties; business combinations or significant changes in a collaborator's business strategy may also adversely affect a collaborator's willingness or ability to complete its obligations under any arrangement; and collaboration arrangements may be terminated or allowed to expire, which would delay the development and may increase the cost of developing our product candidates. Any of these outcomes could harm our business.
Additionally, to the extent we decide to enter into additional collaboration agreements in the future, we may face significant competition in seeking appropriate collaborators. Moreover, collaboration arrangements are complex and time-consuming to negotiate, document, implement and maintain. We may not be successful in our efforts to prudently manage our existing collaborations or to enter new ones should we chose to do so. The terms of new collaborations or other arrangements that we may establish may not be favorable to us.
If we fail to develop market opportunities for ANG-3070 or any future products are smaller than we believe they are, our potential to generate revenue may be adversely affected, and our business may suffer.
The precise incidence and prevalence for all the conditions we currently or may intend to address with ANG-3070 or any future product candidates are unknown. Our projections of both the number of people who have the diseases we target, as well as the subset of people with these diseases who have the potential to benefit from
treatment of ANG-3070 or any future product candidates, are based on our beliefs and estimates. These estimates have been derived from a variety of sources, including the scientific literature, surveys of clinics or market research, and may prove to be incorrect. Further, new trials may change the estimated incidence or prevalence of these diseases. The total addressable market across ANG-3070 and any future product candidates will ultimately depend upon, among other things, the diagnosis criteria included in the final label for each of ANG-3070 and any future product candidates approved for sale for these indications, the availability of alternative treatments and the safety, convenience, cost and efficacy of ANG-3070 and any future product candidates relative to such alternative treatments, acceptance by the medical community and patient access, drug pricing and reimbursement. The number of patients in the United States and other major markets and elsewhere may turn out to be lower than expected, patients may not be otherwise amenable to treatment with our products or new patients may become increasingly difficult to identify or gain access to, all of which would adversely affect our results of operations and our business.
Risks Relating to Our Business and Strategy
We face competition from other biotechnology and pharmaceutical companies and our operating results will suffer if we fail to compete effectively.
The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change. We have competitors in the United States, Europe, and other jurisdictions, including major multinational pharmaceutical companies, established biotechnology companies, specialty pharmaceutical and generic drug companies, and universities and other research institutions. Many of our competitors have greater financial and other resources, such as larger research and development staff and more experienced marketing and manufacturing organizations. Large pharmaceutical companies, in particular, have extensive experience in clinical testing, obtaining regulatory approvals, recruiting patients, and manufacturing pharmaceutical products. These companies also have significantly greater research, sales, and marketing capabilities and collaborative arrangements in our target markets with leading companies and research institutions. Established pharmaceutical companies may also invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds potentially making the product candidates we develop obsolete. As a result of all of these factors, our competitors may succeed in obtaining patent protection and/or FDA approval or discovering, developing, and commercializing drugs for kidney, heart, liver, lung and other diseases we are targeting before we do. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large, established companies. In addition, many universities and private and public research institutes may become active in our target disease areas.
With respect to ANG-3070, Tarpeyo® (budesonide) from Calliditas was granted accelerated approved by the FDA for IgAN, one form of PPKD. Phase 3 programs in PPKD include Atrasentan from Chinook Pharmaceuticals (IgAN, FSGS, Alport), Bardoxolone methyl from Reata Pharmaceuticals (Alport), Iptacopan from Novartis (IgAN), Narsoplimab form Omeros (IgAN), Sibeprenlimab from Visterra/Otsuka Pharmaceuticals (IgAN), Sparsenten from Travere Therapeutics (IgAN, FSGS), and DMX-200 from Dimerix (FSGS). There are two approved therapies, pirfenidone (Esbriet®, sold by Roche/Genentech) for IPF and nintedanib (OFEV®, sold by Boehringer-Ingleheim) for IPF and SSc-ILD. Phase 3 clinical programs potentially competitive with ANG-3070 in IPF include ORG-447 from Agomab Therapeutics, PLN-74809 from Pliant Therapeutics, PRM-151 from Roche/Genentech, and Taladegib from Endeavor Biosciences for IPF.
With respect to competition for our ROCK2 inhibitor, netarsudil ophthalmic solution from Aerie Pharmaceuticals, Inc. was first approved by the FDA in 2017 as a topical agent for reducing intraocular pressure in patients with open-angle glaucoma and ocular hypertension. Other competition in clinical development include Kadmon Holdings, Inc.'s belumosudil (KD025), a ROCK2 inhibitor with reduced selectivity against ROCK1, in the clinic for several indications, including chronic graft versus host disease, systemic sclerosis and IPF. CXC007 from Redx Pharma is in Phase 1 trials. We are also aware of other ROCK2 inhibitors in preclinical development.
Regarding competition for our CYP11B2 inhibitor, CIN-107 from CinCor Pharma is in multiple Phase 2 trials for resistant hypertension, uncontrolled hypertension, and primary aldosteronism. PB6440 from PhaseBio is preparing for Phase 1 trials in 2022 in treatment resistant hypertension
We believe our ability to successfully compete will depend on, among other things:
▪our ability to recruit and enroll patients for our clinical trials;
▪our ability to design and successfully execute appropriate clinical trials;
▪our ability to gain and to maintain positive relationships with regulatory authorities;
▪the efficacy, safety, and reliability of our product candidates;
▪the speed at which we develop our product candidates;
▪our ability to commercialize and market any of our product candidates receiving regulatory approval;
▪the pricing of our products;
▪adequate levels of reimbursement by government entities and by private health insurance plans;
▪our ability to protect intellectual property rights and regulatory exclusivities related to our products;
▪our ability to manufacture and sell commercial quantities of any approved products to the market; and
▪acceptance of our product candidates by downstream customers, including physicians, other healthcare providers, pharmacists, and patients.
If our competitors market products more effective, safer, or less expensive than our products or product candidates, or if any, or these products reach the market sooner we may not achieve commercial success. In addition, the biopharmaceutical industry is characterized by rapid technological change. It may be difficult for us to stay abreast of the rapid changes in each area of research and development. If we fail to stay at the forefront of change, we may be unable to compete effectively. Products developed by our competitors may render our product candidates or products obsolete, less competitive or not economical.
We currently depend on single third-party suppliers for the manufacture and supply of drug substance and potential future commercial product supplies for our product candidates, and any performance failure on the part of our supplier could delay the development and potential commercialization of our product candidates.
We cannot be certain that our drug substance supplier will continue to provide us with sufficient quantities of drug substance, or that our manufacturers will be able to produce sufficient quantities of drug product incorporating such drug substance, to satisfy our anticipated specifications and quality requirements, or that such quantities can be obtained at pricing necessary to sustain acceptable pharmaceutical margins for any of our product candidates, if approved. Our current dependence on a single supplier for our drug substance and the challenges we may face in obtaining adequate supply of drug substance involves several risks, including limited control over pricing, availability, quality and delivery schedules, and such risks may be heightened as a result of the COVID-19 pandemic. Any supply interruption in drug substance or drug product could materially harm our ability to complete our development program for such indications. In addition, any supply interruption in drug substance or drug product could materially harm our ability to complete our other development programs or satisfy commercial demand, if approved, until a new source of supply, if any, could be identified and qualified. For instance, we are conducting our ongoing Phase 2 of ANG-3070 in certain countries in Eastern Europe, namely Georgia, Bulgaria, and Lithuania. If our supply chain in the region is interrupted for any reason, including the current war in Ukraine, the dosing of patients in our Phase 2 clinical trial could be slowed, delayed or stopped. We may be unable to find a sufficient alternative supply channel in a reasonable time or on commercially reasonable terms. Any performance failure on the part of our suppliers could delay the development and potential commercialization of our product candidates, including limiting supplies necessary for clinical trials and regulatory approvals, which would have a material adverse effect on our business.
Moreover, our current supplier of drug substance may not have the capacity to manufacture drug substance in the quantities that we believe will be sufficient to meet our future clinical needs or, in the case of any of our wholly-owned product candidates and those for which we retain the right to commercialize, anticipated market demand or to enable us to achieve the economies of scale necessary to reduce the manufacturing cost of applicable drug substance. While we are currently engaged in discussions with a potential second supplier for clinical and commercial drug substance, such negotiations may not lead to a definitive agreement on acceptable terms, or at all, which could have a material adverse effect on our business. With respect to any of our wholly-owned product candidates and those for which we retain the right to commercialize, we expect that we will be able to develop a supply chain with multiple suppliers and significantly decrease our cost of goods within the first several years of commercialization following the receipt of any approvals. However, if our contract manufacturer for drug substance is unable to source, or we are unable to purchase, sufficient quantities of materials necessary for the production of the drug substance for such product candidates, the ability of such product candidates to reach their market potential or to be timely launched, would be delayed or suffer from a shortage in supply, which would impair our ability to generate revenue from sales. If there is a disruption to our contract manufacturers' or suppliers' relevant operations, we could have no other means of producing drug substance until they restore the affected facilities or
we or they procure alternative manufacturing facilities. Additionally, any damage to or destruction of our contract manufacturers' or suppliers' facilities or equipment may significantly impair our ability to manufacture drug substance for our product candidates on a timely basis.
We depend on third-party contractors for a substantial portion of our operations and may not be able to control their work as effectively as if we performed these functions ourselves. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may be unable to obtain regulatory approval for or commercialize our product candidates, if approved.
We outsource substantial portions of our operations to third-party service providers, including the conduct of preclinical studies and clinical trials, collection and analysis of data, and manufacturing. Our agreements with third-party service providers and CROs are on a study-by-study and project-by-project basis. Typically, we may terminate the agreements with notice and are responsible for the supplier's previously incurred costs. In addition, any CRO we retain will be subject to the FDA's and EMA's regulatory requirements and similar standards outside of the United States and Europe, and we do not have direct control over compliance with these regulations by these providers. Consequently, if these providers do not adhere to applicable governing practices and standards, the development and commercialization of our product candidates could be delayed or stopped, which could severely harm our business and financial condition.
Because we have relied on third parties, our internal capacity to perform these functions is limited to contractual oversight. Outsourcing these functions involves the risk third parties may not perform to our standards, may not produce results in a timely manner or may fail to perform at all. This challenge has been made more difficult by the COVID-19 pandemic and resulting shelter-in-place and stay-at-home restrictions, which are driving greater dependency on electronic monitoring of trial sites. Such monitoring can be less reliable and creates additional exposure to data privacy and cybersecurity issues. Additionally, the facilities at which any of our product candidates are manufactured must be the subject of a satisfactory inspection before the FDA or the regulators in other jurisdictions approve the product candidate manufactured at that facility. We are completely dependent our third-party vendors for compliance with cGMP requirements of United States and non-United States regulators for the manufacture of our finished products. If our manufacturers cannot successfully manufacture material conforming to our specifications and cGMPs of any applicable governmental agency, our product candidates will not be approved or, if already approved, may be subject to recalls or demands by regulatory agencies to stop selling the product until manufacturing issues are resolved. In addition, our third-party service providers and CROs that perform nonclinical studies and clinical trials on our behalf must comply with applicable Good Laboratory Practice (GLP) requirements for animal testing and GCP requirements for clinical trials, where any failure to comply with such requirements could result in the FDA or other regulatory authorities refusing to accept data obtained in violation of such requirements and possibly initiating other enforcement action against us and our contractors.
We and our consultants monitor our third parties for performance and adherence to protocols. We have had to replace clinical sites because of poor enrollment. In addition, the use of third-party service providers requires us to disclose our proprietary information to these parties (including sensitive data such as personal information or clinical data), which could increase the risk this information will be misappropriated or compromised in connection with a security breach, cyber-attack or other security incident. There are a limited number of third-party service providers specializing in or having the expertise required to achieve our business objectives. Identifying, qualifying, and managing performance of third-party service providers can be difficult, time consuming, and cause delays in our development programs. We currently have a relatively small number of employees, which limits the internal resources we have available to identify and monitor third-party service providers. To the extent we are unable to identify, retain, and successfully manage the performance of third-party service providers in the future, our business may be adversely affected, and we may be subject to the imposition of civil or criminal penalties if their conduct of clinical trials violates applicable law.
We will need to maintain a good relationship with our employees to maintain our operations. A deterioration in our relationships with our employees could have an adverse impact on our business.
On January 4, 2022, we announced a reduction in force impacting somewhat less than half of our employees. Our decision to engage in this reduction results from an assessment of our internal resources needs, given the results of the Phase 3 study of ANG-3777 in patients at risk for DGF would likely not support a regulatory approval in that population and the results from a Phase 2 trial in CSA-AKI would not support a Phase 3 trial in the indication. This reduction was a cost-cutting measure across the organization to support our 2022 primary focus on the clinical
development of its investigational asset ANG-3070, a highly selective, oral tyrosine kinase receptor inhibitor in development as a treatment for fibrotic diseases, particularly in the kidney and lung, as well as advancing preclinical assets to IND-enabling studies. This has caused substantial uncertainty as to job security for the rest of our employees. Maintaining good relationships with our employees and operating effectively and efficiently across our organization are crucial to our operations and our success. If we are unable to successfully maintain such relationships or manage the uncertainty as a result of the reduction in the number of our employees, and the complexity of operations, our business may be adversely affected. See "Item 1. Business—Human Capital Resources."
We may not be able to manage our business effectively if we are unable to attract and retain key personnel and consultants.
We may not be able to attract or retain qualified management, finance, scientific, clinical, and commercial personnel and consultants due to the intense competition for qualified personnel and consultants among biotechnology, pharmaceutical, and other businesses. If we are not able to attract and retain necessary personnel and consultants to accomplish our business objectives, we may experience constraints significantly impeding the achievement of our development objectives, our ability to raise additional capital, and our ability to implement our business strategy.
We are highly dependent upon our senior management, particularly our Chief Executive Officer, Dr. Jay Venkatesan, as well as on the development, regulatory, commercialization, and business development expertise of the rest of our senior management and other senior personnel across preclinical, clinical, translational medicine, legal, and regulatory affairs. If we lose one or more of our executive officers or key employees or consultants, our ability to implement our business strategy successfully could be seriously harmed. Any of our executive officers, key employees, or consultants may terminate their employment and/or engagement with us at any time. Replacing executive officers, key employees, and consultants 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 develop, gain regulatory approval of, and commercialize products successfully. Competition to hire and retain employees and consultants from this limited pool is intense, and we may be unable to hire, train, retain, or motivate these additional key personnel and consultants. Our failure to retain key personnel or consultants could materially harm our business.
We have scientific and clinical advisors and consultants who assist us in formulating and implementing our research, development, and clinical strategies. These advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities limiting their availability to us and typically they will not enter into non-compete agreements with us. If a conflict of interest arises between their work for us and their work for another entity, we may lose their services. In addition, our advisors may have arrangements with other companies to assist those companies in developing products or technologies competitive with ours.
We expect a number of factors to cause our operating results to fluctuate on a quarterly and annual basis, which may make it difficult to predict our future performance.
We are a clinical -stage biopharmaceutical company that has been operating since 1998. Our operations to date have been limited to researching and developing product candidates, including conducting preclinical studies and clinical trials. We have not yet obtained regulatory approvals for any of our product candidates. Consequently, any predictions made about our future success or viability may not be as accurate as they could be if we had a longer operating history or approved products on the market. Our financial condition and operating results are expected to significantly fluctuate from quarter-to-quarter or year-to-year due to a variety of factors, many of which are beyond our control. Factors relating to our business that may contribute to these fluctuations include, but are not limited to:
▪the timing and cost of, and level of investment in, research, development, including the needs for additional clinical trials, and, if approved, commercialization activities relating to our product candidates, which may change from time to time;
▪delay in or the success of our clinical trials through all phases of clinical development, including our ongoing clinical trials of ANG-3070;
▪potential adverse events associated with our product candidates potentially delaying or preventing approval or causing an approved drug to be taken off the market;
▪any delays in regulatory review and approval by regulatory authorities of our product candidates in clinical development, including ANG-3070;
▪our ability to obtain additional funding to develop our product candidates;
▪our ability to commercialize and obtain market acceptance and reimbursement for our approved products; and
▪our dependency on third-party manufacturers to manufacture and distribute our products and key ingredients.
We face potential product liability exposure, and if successful claims are brought against us, we may incur substantial liability for a product candidate and may have to limit its commercialization.
The use of our product candidates in clinical trials and the sale of any products for which we may obtain marketing approval expose us to the risk of product liability claims. Product liability claims may be brought against us or our collaborators by participants enrolled in our clinical trials, patients, healthcare providers, or others using, administering, or selling our products. If we cannot successfully defend ourselves against any such claims, we would incur substantial liabilities. Regardless of merit or eventual outcome, product liability claims may result in:
▪withdrawal of clinical trial participants;
▪termination of clinical trial sites or entire trial programs;
▪costs of related litigation;
▪substantial monetary awards to patients or other claimants;
▪decreased demand for our product candidates and loss of revenues;
▪impairment of our business reputation;
▪diversion of management and scientific resources from our business operations; and
▪the inability to commercialize our product candidates.
We have obtained limited product liability insurance coverage for our clinical trials in the United States and in selected other jurisdictions where we are conducting clinical trials. Our insurance coverage may not reimburse us or may not be sufficient to reimburse us for any expenses or losses we may suffer. Moreover, insurance coverage is becoming increasingly expensive and, in the future, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to product liability. Large judgments have been awarded in class action lawsuits based on drugs with unanticipated side effects. A successful product liability claim or series of claims brought against us, particularly if judgments exceed our insurance coverage, could decrease our cash resources and adversely affect our business.
Our insurance policies are expensive and only protect us from some business risks, which will leave us exposed to significant uninsured liabilities.
We do not carry insurance for all categories of risk that our business may encounter. Some of the policies we currently maintain include property, general liability, employment benefits liability, business automobile, workers' compensation, products liability, malicious invasion of our electronic systems, and clinical trials (U.S. and foreign), and directors' and officers', employment practices and fiduciary liability insurance. We do not know, however, if we will be able to maintain insurance with adequate levels of coverage. Any significant uninsured liability may require us to pay substantial amounts, which would adversely affect our financial position and results of operations.
Under the terms of the government grant funding we have received, the government may compel us to license to a third party, or suspend, terminate or withhold grant funding.
A significant amount of our discovery and initial clinical research has been funded principally by United States government grants and contracts. As with all other pharmaceutical research programs supported in part by federal research dollars, conducting research under federal grants required us to grant the U.S. government a nonexclusive, nontransferable, irrevocable, paid-up license for the government to practice or have the invention practiced on its behalf throughout the world. Under certain circumstances, the government can require the grantee to license a third party, or the government may take title and grant a license itself, known as march-in rights, which may occur if the invention is not brought to practical use within a reasonable time, if health or safety issues arise, if public use of the invention is in jeopardy, or if other legal requirements are not satisfied. Although, to our knowledge, the U.S. government has never forced a grantee to license a third party or taken title and granted a license itself,
these march-in rights are available to the government, and we cannot assure you that the government will not exercise such rights in the future.
Under the terms and conditions of the government grant funding, we are obligated to comply with various reporting requirements and to take certain administrative actions. Material noncompliance with the terms and conditions of the grant funding may result in one or more enforcement actions by the grant agency. These enforcement actions include denying funds for the cost of funded activities, suspending the grant in whole or in part, pending corrective action, and withholding further grant awards. The grant agency may also terminate the grant for cause, or take other legally available remedies.
Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.
We have incurred substantial losses during our history and do not expect to become profitable in the near future, and we may never achieve profitability. To the extent that we continue to generate taxable losses, unused losses will carry forward to offset a portion of future taxable income, if any, until such unused losses expire, if ever. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an "ownership change," generally defined as a greater than 50 percentage point change (by value) in its equity ownership by certain stockholders over a rolling three-year period, the corporation's ability to use its pre-change net operating loss carryforwards (NOLs) and other pre-change tax attributes (such as research and development tax credits) to offset its post-change income or taxes may be limited. We have not performed an analysis to assess whether an ownership change has occurred. There is also a risk that due to regulatory changes, such as suspensions on the use of NOLs, or other unforeseen reasons, our existing NOLs could expire or otherwise become unavailable to offset future income tax liabilities. Under the TCJA, as modified by the Coronavirus Aid, Relief and Economic Security Act (the CARES Act), the amount of post-2017 NOLs that are permitted to deduct from U.S. federal income taxes for tax years beginning after December 31, 2020 is limited to 80% of our taxable income in such year, where taxable income is determined without regard to the NOL deduction itself. The TCJA, as modified by the CARES Act, generally eliminates the ability to carry back any NOLs to prior taxable years for tax years beginning after December 31, 2020, while allowing post-2017 unused NOLs to be carried forward indefinitely without expiration. Additionally, state NOLs generated in one state cannot be used to offset income generated in another state. For these reasons, even if we attain profitability, we may be unable to use a material portion of our NOLs and other tax attributes.
Any claims relating to improper handling, storage or disposal of hazardous materials used in our business could be costly and delay our research and development efforts.
Our research and development activities involve the controlled use of potentially harmful hazardous materials, including volatile solvents and chemicals causing cancer. Our operations also produce hazardous waste products. We face the risk of contamination or injury from the use, storage, handling or disposal of these materials. We are subject to federal, state and local laws and regulations governing the use, storage, handling and disposal of these materials and specified waste products. The cost of compliance with these laws and regulations could be significant, and current or future environmental regulations may impair our research, development or production efforts. If one of our employees were accidentally injured from the use, storage, handling, or disposal of these materials, the medical costs related to their treatment would be covered by our workers' compensation insurance policy. However, we do not carry specific hazardous waste insurance coverage and our general liability insurance policy specifically excludes coverage for damages and fines arising from hazardous waste exposure or contamination. Accordingly, in the event of contamination or injury, we could be subject to criminal sanctions or fines or be held liable for damages, our operating licenses could be revoked, or we could be required to suspend or modify our operations and our research and development efforts.
Risks Relating to Our Intellectual Property
It is difficult and costly to protect our proprietary rights, and we may not be able to ensure their protection. If our patent position and potential regulatory exclusivity do not adequately protect our product candidates, others could compete against us more directly, which would harm our business, possibly materially.
Our commercial success will depend in part on obtaining and maintaining patent protection and trade secret protection of our current and future product candidates, and their methods of manufacture and use. Our ability to stop third parties from making, using, selling, offering to sell or importing our product candidates is dependent upon the extent to which we have rights under valid and enforceable patents and/or trade secrets that cover these
activities. The patent positions of biotechnology and pharmaceutical companies can be highly uncertain and involve complex legal and factual questions. No consistent policy regarding the breadth of claims allowed in pharmaceutical patents has emerged to date in the United States or in many jurisdictions outside of the United States. Changes in either the patent laws or interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property. Accordingly, we cannot predict the breadth of claims that may be issued in relevant jurisdictions from our present or future patent filings, or those we license from third parties, and further cannot predict the extent to which we will be able to enforce such issued claims in jurisdictions important to our business. If any patents we obtain or license are deemed invalid and unenforceable, our ability to commercialize or license our technology could be adversely affected.
It is possible that others have filed, and in the future may file, patent applications covering products and technologies that are similar, identical or competitive to ours, or that are otherwise important to our business. We cannot be certain that any patent filings owned by a third party will not have priority over patent applications filed or in-licensed by us, or that we or our licensors will not be involved in interference, opposition or invalidity proceedings before United States or foreign patent offices. The costs of defending our patents or enforcing our proprietary rights in post-issuance administrative proceedings and litigation can be substantial and the outcome can be uncertain. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, and/or could allow third parties to commercialize our technology or products and compete directly with us, without payment to us. Furthermore, third party filings may issue as patents that are infringed by our manufacture or commercialization of our products. Licenses may not be available to such third party patents, and challenges to their validity or infringement may be expensive and may not succeed. If the breadth or strength of protection provided by our patents and patent applications is threatened, or if we are perceived or found to infringe intellectual property rights of others, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates, and could impede or preclude our ability to commercialize our products.
The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our owned and licensed patents may be challenged in the courts or patent offices in the United States and abroad. We may become involved in opposition, derivation, reexamination, inter partes review, post-grant review or interference proceedings challenging our patent rights or the patent rights of others. Such challenges may result in loss of exclusivity or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, any of which could limit our ability to stop others from using or commercializing similar or identical technology and products, and/or limit the duration of the patent protection of our technology and products.
The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:
▪we might not have been the first to make the inventions covered by our pending patent applications or patents;
▪others may be able to develop a product similar to, or better than, ours in a way that is not covered by the claims of our patents;
▪we might not have been the first to file patent applications for these inventions;
▪others may independently develop similar or alternative technologies or duplicate any of our technologies;
▪any patents that we have or obtain may not provide us with any competitive advantages;
▪patents have limited term and geographic scope; we may not be able to secure patents that last long enough and are in relevant jurisdictions to effectively limit competition;
▪we may not develop additional proprietary technologies that are patentable; or
▪the patents of others may have an adverse effect on our business.
Without patent protection for our compounds, pharmaceutical compositions, or formulations of our product candidates, our ability to stop others from using or selling our product, or other competitive products including our compounds, may be limited.
If the patent applications we hold or have in-licensed with respect to present or future product candidates fail to issue, if their breadth and/or strength of protection is limited or challenged, or if they fail to provide meaningful exclusivity for present or future product candidates, it could dissuade companies from collaborating with us to
develop future candidates and threaten our ability to commercialize future commercial products. Any such outcome could have a materially adverse effect on our business.
We may also rely on trade secrets to protect our technology, especially where we do not believe patent protection is appropriate or feasible. However, trade secrets are difficult to protect. Although we use reasonable efforts to protect our trade secrets, our employees, consultants, contractors, outside scientific collaborators, and other advisors may unintentionally or willfully disclose our information to competitors. Enforcing a claim that a third party illegally obtained and is using any of our trade secrets is expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the United States are sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how.
If we do not obtain protection under the Hatch-Waxman Act and similar legislation outside of the United States by extending the patent terms and obtaining data exclusivity for our product candidates, our business may be materially harmed.
Depending upon the timing, duration and specifics of FDA marketing approval of our product candidates, if any, one or more of our United States patents may be eligible for limited patent term restoration under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Act. The Hatch-Waxman Act permits a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process.
However, we may not be granted an extension of patent term because, for example, of failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable requirements. 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 of any such extension is less than what we request, the period during which we will have the right to exclusively market our product will be shortened and our competitors may obtain approval of competing products following our patent expiration, and our revenue could be reduced, possibly materially.
Any trademarks we may obtain may be infringed or successfully challenged, resulting in harm to our business.
We expect to rely on trademarks as one means to distinguish any of our product candidates that are approved for marketing from the products of our competitors. We have not yet selected trademarks for our product candidates, and have not yet begun the process of applying to register trademarks for our product candidates. Once we select trademarks and apply to register them, our trademark applications may not be approved. Third parties may oppose our trademark applications or otherwise challenge our use of the trademarks. In the event that our trademarks are successfully challenged, we could be forced to rebrand our products, which could result in loss of brand recognition and could require us to devote resources to advertising and marketing new brands. Our competitors may infringe our trademarks, and we may not have adequate resources to enforce our trademarks.
In addition, any proprietary name we propose to use with our product candidate in the United States must be approved by the FDA, regardless of whether we have registered it, or applied to register it, as a trademark. The FDA typically conducts a review of proposed product names, including an evaluation of the potential for confusion with other product names. If the FDA objects to any of our proposed proprietary product names, we may be required to expend significant additional resources in an effort to identify a suitable proprietary product name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA.
Changes in U.S. patent law or the patent law of other countries or jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our products.
The United States has enacted and implemented wide-ranging patent reform legislation. The U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on actions by the U.S. Congress, the Federal Courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that could weaken our ability to obtain new patents or to enforce patents that we have obtained or licensed, or that we might obtain or license in the future. Similarly, changes in patent law and regulations in other countries or
jurisdictions or changes in the governmental bodies that enforce them or changes in how the relevant governmental authority enforces patent laws or regulations may weaken our ability to obtain new patents or to enforce patents that we have obtained or licensed or that we may obtain or license in the future.
We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights.
If we choose to go to court to stop another party from using the inventions claimed in any patents we obtain, that individual or company has the right to ask the court to rule that such patents are invalid or should not be enforced against that third party. These lawsuits are expensive, would consume time and resources and would divert the attention of managerial and scientific personnel even if we were successful in stopping the infringement of such patents. In addition, there is a risk the court will decide that such patents are not valid and we do not have the right to stop the other party from using the inventions. There is also a risk that, even if the validity of such patents is upheld, the court will refuse to stop the other party on the grounds that such other party's activities do not infringe our patents. In addition, the United States Supreme Court has recently modified some tests used by the USPTO in granting patents over the past 20 years, which may decrease the likelihood that we will be able to obtain patents and increase the likelihood of challenge of any patents we obtain or license.
We may infringe the intellectual property rights of others, which may prevent or delay our product development efforts and stop us from commercializing or increase the costs of commercializing our product candidates.
Our success will depend in part on our ability to operate without infringing the proprietary rights of third parties. We cannot guarantee that our products or product candidates, or their manufacture or use, will not infringe third-party patents. Furthermore, a third party may claim we or our manufacturing or commercialization collaborators are using inventions covered by the third party's patent rights. It is also possible a third party might allege our products or product candidates, or their manufacture or use, incorporate or rely on trade secrets improperly received from the third party. A third party alleging violations of their intellectual property rights may go to court to stop us from engaging in our normal operations and activities, including making or selling our product candidates. Defense of such claims, regardless of their merit, are costly and could affect our results of operations and divert the attention of managerial and scientific personnel.
There is a risk a court would decide that we or our commercialization collaborators are infringing the third party's intellectual property rights and would order us or our collaborators to stop relevant activities. In that event, we or our commercialization collaborators may not have a viable way to avoid the infringement and may need to halt commercialization of the relevant product. In addition, there is a risk a court will order us or our collaborators to pay the other party damages for having infringed the other party's intellectual property rights. In the future, we may agree to indemnify our commercial collaborators against certain intellectual property infringement claims brought by third parties. The pharmaceutical and biotechnology industries have produced a proliferation of patents, and it is not always clear to industry participants, including us, which patents cover various types of products or methods of use. The coverage of patents is subject to interpretation by the courts, and the interpretation is not always uniform.
If we are sued for patent or other intellectual property (e.g., trade secret, trademark, etc.) infringement, we could incur significant costs, and delays in our product development or commercialization.
For example, in order to prevail in a suit alleging patent infringement, we would need to demonstrate that our products or methods either do not infringe the claims of the relevant patent or that the patent claims are invalid, and we may not be able to do this. Proving invalidity of a patent is difficult. For example, in the United States, proving invalidity requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents. If we are unable to avoid infringing the patent rights of others, we may be required to seek a license, which may not be available, defend an infringement action or challenge the validity of the patents in court. Patent litigation is costly and time consuming.
We cannot be certain others have not filed patent applications or obtained issued patents for technology that we need to use to commercialize our products, at least because:
▪some patent applications in the United States may be maintained in secrecy until the patents are issued;
▪patent applications in the United States are typically not published until 18 months after the priority date;
▪even published patent applications and patents may be difficult or impossible to identify if their records in available databases are incomplete or inaccurate, or are in a language that is not readily amendable to searching in English; and
▪publications in the scientific literature often lag behind actual discoveries.
Our most advanced programs are currently in clinical trials. Patent laws of various jurisdictions, including the United States, exempt clinical trial activities, and most or all preclinical work, from patent infringement. These exemptions expire when clinical work is completed and application for a commercialization license (e.g., a New Drug Application) is submitted to a relevant regulatory authority (e.g., the FDA). Accordingly, we cannot be confident that third parties will not allege patent infringement with respect to our existing products or programs merely because they have not yet done so.
Our competitors may have filed, and may in the future file, patent applications covering technology like ours. Any such patent application may have priority over our patent applications, which could further require us to obtain rights to issued patents covering such technologies. If another party has filed a United States patent application on inventions similar to ours, we may have to participate in an interference or derivation proceeding declared by the USPTO to determine priority of invention in the United States. The costs of these proceedings could be substantial, and it is possible that such efforts would be unsuccessful if, unbeknownst to us, the other party had independently arrived at the same or similar invention prior to our own invention, resulting in a loss of our United States patent position with respect to such inventions, and granting such position to the third party, so that we may need to seek a license from such third party to continue our use of the technologies, which license might not be available, or might impose significant costs.
Other countries have similar laws that permit secrecy of patent applications and may be entitled to priority over our applications in such jurisdictions.
In addition, we may be subject to claims that we are infringing other intellectual property rights, such as trademarks or copyrights, or misappropriating the trade secrets of others, and to the extent that our employees, consultants or contractors use intellectual property or proprietary information owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.
We may not have sufficient resources to bring actions alleging intellectual property infringement to a successful conclusion. In addition, if we do not obtain a license, develop or obtain non-infringing technology, fail to defend an infringement action successfully or have infringed patents declared invalid, we may incur substantial monetary damages, encounter significant delays in bringing our product candidates to market and be precluded from manufacturing or selling our product candidates. Furthermore, even if we are successful in proceedings relating to alleged intellectual property infringement or misappropriation, we may incur substantial costs and divert management's time and attention in pursuing these proceedings, which could have a material adverse effect on us.
Some of our competitors may be able to sustain the costs of complex litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations.
Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.
Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to be paid to the USPTO and various governmental patent agencies outside of the United States in several stages over the lifetime of the patents and/or applications. We have systems in place to remind us to pay these fees, and we employ an outside firm and rely on our outside counsel to pay these fees due to the USPTO and non-United States patent agencies. The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. We employ reputable law firms and other professionals to help us comply, and in many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules. However, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such
an event, our competitors might be able to enter the market and this circumstance could have a material adverse effect on our business.
Risks Relating to Our Common Stock
Our stock price may be volatile and you may not be able to resell shares of our common stock at or above the price you paid.
The trading price of our common stock could be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control. These factors include those discussed in this "Risk Factors" section of this report and others such as:
▪results from, and any delays in, our clinical trials for ANG-3070;
▪results of clinical trials of our competitors' products;
▪competition from existing products or new products that may emerge;
▪announcements by academic, guideline publishers or other third parties challenging the fundamental premises underlying our approach to treating PPKDs like FSGS and IgAN or IPF;
▪failure or discontinuation of any of our research and development programs;
▪manufacturing setbacks or delays of or issues with the supply of the materials for ANG-3070;
▪announcements relating to future licensing, collaboration or development agreements;
▪sales of our common stock by or announcements relating to our existing collaborators, including Vifor Pharma;
▪acquisitions and sales of new products, technologies or businesses;
▪quarterly variations in our results of operations or those of our future competitors;
▪changes in earnings estimates or recommendations by securities analysts;
▪announcements by us or our competitors of new products, significant contracts, commercial relationships, acquisitions or capital commitments;
▪developments with respect to intellectual property rights;
▪our commencement of, or involvement in, litigation;
▪changes in financial estimates or guidance, including our ability to meet our future revenue and operating profit or loss estimates or guidance;
▪any major changes in our board of directors or management;
▪new legislation in the United States or relevant foreign jurisdictions relating to the sale or pricing of pharmaceuticals;
▪FDA or other U.S. or foreign regulatory actions affecting us or our industry;
▪product liability claims or other litigation or public concern about the safety of ANG-3070;
▪market conditions in the pharmaceutical and biotechnology sectors; and
▪general economic conditions in the United States and abroad.
In addition, the stock markets in general, and the markets for pharmaceutical and biotechnology stocks in particular, have experienced extreme volatility that may have been unrelated to the operating performance of the issuer. These broad market fluctuations may adversely affect the trading price or liquidity of our common stock. In the past, when the market price of a stock has been volatile, holders of that stock have sometimes instituted securities class action litigation against the issuer. If we were to become involved in securities litigation, we could incur substantial costs and resources and the attention of our management could be diverted from the operation of our business.
An active, liquid and orderly market for our common stock may not be sustained.
Our common stock is currently listed on the Nasdaq Global Select Market under the symbol “ANGN”. The price for our common stock may vary and an active or liquid market in our common stock may not be sustained. The lack of an active market may impair your ability to sell your shares at the time you wish to sell them or at a price that you consider reasonable. An inactive market may also impair our ability to raise capital by selling shares and may impair our ability to acquire other businesses, applications, or technologies using our shares as consideration.
If we sell shares of our common stock in future financings, stockholders may experience immediate dilution and, as a result, our stock price may decline.
We may, from time to time, issue additional shares of common stock at a discount from the current trading price of our common stock, including pursuant to our 2021 Incentive Award Plan and 2021 Employee Stock Purchase Plan. As a result, our stockholders would experience immediate dilution upon the purchase of any shares of our common stock sold at such discount. In addition, as opportunities present themselves, we may enter into financing or similar arrangements in the future, including the issuance of debt securities, preferred stock or common stock. If we issue common stock or securities convertible into common stock, our common stockholders would experience additional dilution and, as a result, our stock price may decline.
We identified material weaknesses in our internal control over financial reporting and we may identify additional material weaknesses in the future that may cause us to fail to meet our reporting obligations or result in material misstatements of our financial statements. If we fail to remediate any material weaknesses or if we otherwise fail to establish and maintain effective control over financial reporting, our ability to accurately and timely report our financial results could be adversely affected.
We have identified control deficiencies in the design and operation of our internal control over financial reporting that constituted material weaknesses. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected on a timely basis.
The material weaknesses identified in our internal control over financial reporting related to (i) insufficient resources with knowledge and expertise in U.S. GAAP to properly evaluate certain complex transactions, including debt instruments and equity instruments; and (ii) insufficient financial reporting and close controls to ensure that incurred expenses are accrued at period end and deliverables from third party contractors are reviewed for accuracy. We have taken a number of actions to remediate these material weaknesses, including engaging SEC compliance and technical accounting consultants to assist in evaluating transactions for conformity with U.S. GAAP; hiring additional finance and accounting personnel to augment accounting staff and to provide more resources for complex accounting matters and financial reporting; and strengthening our financial reporting and close relating to incurred expenses by ensuring our data capture procedures are clearly defined and that responsible personnel, including supervisory personnel, have adequate training regarding the process and expectation.
However, we are still in the process of implementing these processes and controls and we cannot assure you that these measures will be sufficient to remediate the material weaknesses that have been identified or prevent future material weaknesses or significant deficiencies from occurring.
If we are unable to successfully remediate the existing material weaknesses in our internal control over financial reporting, or discover additional material weaknesses in the future, the accuracy and timing of our financial reporting, and our stock price, may be adversely affected and we may be unable to maintain compliance with the applicable stock exchange listing requirements.
We are an "emerging growth company" and as a result of the reduced disclosure and governance requirements applicable to emerging growth companies, our common stock may be less attractive to investors.
We are an "emerging growth company," as defined in Jumpstart Our Business Act of 2012, (JOBS Act), and we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and obtaining stockholder approval of any golden parachute payments not previously approved. In addition, as an "emerging growth company," the JOBS Act allows us to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. We have elected to use this extended transition period under the JOBS Act. As a result, our financial statements may not be comparable to the financial statements of issuers who are required to comply with the effective dates for new or revised accounting standards that are applicable to public companies, which may make comparison of our financials to those of other public companies more difficult. Even after we no longer qualify as an emerging growth company, we may still qualify as a "smaller reporting company"
which would allow us to take advantage of many of the same exemptions from disclosure requirements including not being required to comply for a period of time with the auditor attestation requirements of Section 404, and reduced disclosure obligations regarding executive compensation in this report and our periodic reports and proxy statements.
We cannot predict if investors will find our common stock less attractive because we will rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile. We may take advantage of these reporting exemptions until we are no longer an emerging growth company or smaller reporting company.
We have completed and may in the future complete related party transactions that were not and may not be conducted on an arm's length basis.
We have in the past and continue to be party to certain transactions with certain entities affiliated with Dr. Goldberg, director and Chairman Emeritus on our Board, as well as certain of his immediate family members. For instance, in November 2013, we granted Ohr Cosmetics, LLC (Ohr), an affiliated company, an exclusive worldwide license, with the right to sublicense, under our patent rights covering one of our CYP26 inhibitors, ANG-3522, for the use in treating conditions of the skin or hair. We own, and the family of Dr. Goldberg, owns approximately 2.4% and 80.6%, respectively, of the membership interests in Ohr. Dr. Goldberg's son is the manager of Ohr.
In addition, we rent office and laboratory space in Uniondale, New York from NovaPark LLC (NovaPark), an affiliated company, under a lease that expires on June 20, 2026. The space that we rent is part of an approximately 110,000-square-foot general laboratory and development facility (NovaPark Facility) for biological and chemistry research owned by NovaPark. We own, and Dr. Goldberg, and Rina Kurz, Dr. Goldberg's spouse, own 10%, 45% and 45%, respectively, of the membership interests in NovaPark.
Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable and may lead to entrenchment of management.
Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could delay or prevent changes in control or changes in our management without the consent of our board of directors. These provisions include the following:
▪a classified board of directors with three-year staggered terms, which may delay the ability of stockholders to change the membership of a majority of our board of directors;
▪no cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates;
▪the exclusive right of our board of directors to elect a director to fill a vacancy created by the expansion of the board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors;
▪the ability of our board of directors to authorize the issuance of shares of preferred stock and to determine the price and other terms of those shares, including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquiror;
▪the ability of our board of directors to alter our amended and restated bylaws without obtaining stockholder approval;
▪the required approval of at least 66 2/3% of the shares entitled to vote at an election of directors to adopt, amend or repeal our amended and restated bylaws or repeal the provisions of our amended and restated certificate of incorporation regarding the election and removal of directors;
▪a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;
▪the requirement that a special meeting of stockholders may be called only by our chief executive officer or president or chairperson of the board of directors or by the board of directors, which may delay the ability of our stockholders to force consideration of a proposal or to take action, including the removal of directors; and
▪advance notice procedures that stockholders must comply with in order to nominate candidates to our board of directors or to propose matters to be acted upon at a stockholders' meeting, which may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect the acquiror's own slate of directors or otherwise attempting to obtain control of us.
We are also subject to the anti-takeover provisions contained in Section 203 of the Delaware General Corporation Law. Under Section 203, a corporation may not, in general, engage in a business combination with any holder of 15% or more of its capital stock unless the holder has held the stock for three years or, among other exceptions, the board of directors has approved the transaction. For a description of our capital stock, see "Description of Capital Stock."
Our amended and restated certificate of incorporation and amended and restated bylaws provide for an exclusive forum in the Court of Chancery of the State of Delaware for certain disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.
Our amended and restated certificate of incorporation and amended and restated bylaws provide that the Court of Chancery of the State of Delaware (or, in the event that the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware or other state courts of the State of Delaware) is the exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a claim of breach of fiduciary duty, any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our amended and restated certificate of incorporation or our amended and restated bylaws, or any action asserting a claim against us that is governed by the internal affairs doctrine; provided that, the exclusive forum provision will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction; and provided further that, if and only if the Court of Chancery of the State of Delaware dismisses any such action for lack of subject matter jurisdiction, such action may be brought in another state or federal court sitting in the State of Delaware. Our amended and restated certificate of incorporation and amended and restated bylaws also provide that the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action against us or any of our directors, officers, employees or agents and arising under the Securities Act. Nothing in our amended and restated certificate of incorporation or amended and restated bylaws precludes stockholders that assert claims under the Exchange Act from bringing such claims in state or federal court, subject to applicable law.
We believe these provisions may benefit us by providing increased consistency in the application of Delaware law and federal securities laws by chancellors and judges, as applicable, particularly experienced in resolving corporate disputes, efficient administration of cases on a more expedited schedule relative to other forums and protection against the burdens of multi-forum litigation. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, other employees or stockholders, which may discourage lawsuits with respect to such claims, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder. Furthermore, the enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive-forum provisions, and there can be no assurance that such provisions will be enforced by a court in those other jurisdictions. If a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation and amended and restated bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition.
General Risk Factors
Unstable market and economic conditions may have serious adverse consequences on our business, financial condition and stock price.
The global credit and financial markets have experienced extreme volatility and disruptions in the past several years, including most recently as a result of the COVID-19 pandemic and the Russian invasion of Ukraine. Such volatility and disruptions have caused and may continue to cause severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability. There can be no assurance that further deterioration in credit and financial markets and confidence in economic conditions will not occur. Our general business strategy may be adversely affected by any such economic downturn, volatile business environment or continued unpredictable and unstable market conditions. If the current equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult, more costly and more dilutive. Failure to secure any necessary financing in a timely manner and on
favorable terms could have a material adverse effect on our growth strategy, financial performance and stock price and could require us to delay or abandon clinical development plans. In addition, there is a risk that one or more of our current service providers, manufacturers and other partners may not survive an economic downturn, which could directly affect our ability to attain our operating goals on schedule and on budget.
Our business could be affected by litigation, government investigations and enforcement actions.
We currently operate in a number of jurisdictions in a highly regulated industry and we could be subject to litigation, government investigation and enforcement actions on a variety of matters in the United States. or foreign jurisdictions, including, without limitation, intellectual property, regulatory, product liability, environmental, whistleblower, false claims, privacy, anti-kickback, anti-bribery, securities, commercial, employment, and other claims and legal proceedings which may arise from conducting our business. Any determination that our operations or activities are not in compliance with existing laws or regulations could result in the imposition of fines, civil and criminal penalties, equitable remedies, including disgorgement, injunctive relief, and/or other sanctions against us, and remediation of any such findings could have an adverse effect on our business operations.
Legal proceedings, government investigations and enforcement actions can be expensive and time consuming. An adverse outcome resulting from any such proceeding, investigations or enforcement actions could result in significant damages awards, fines, penalties, exclusion from the federal healthcare programs, healthcare debarment, injunctive relief, product recalls, reputational damage and modifications of our business practices, which could have a material adverse effect on our business and results of operations.
Our employees, principal investigators, consultants and commercial partners may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements and insider trading.
We are exposed to the risk of fraud or other misconduct by our employees, principal investigators, consultants and commercial partners. Misconduct by these parties could include intentional failures, reckless and/or negligent conduct or unauthorized activities that violates (i) the laws and regulations of the FDA and other regulatory authorities, including those laws requiring the reporting of true, complete and accurate information to such authorities, (ii) manufacturing standards, (iii) federal and state data privacy, security, fraud and abuse and other healthcare laws and regulations in the United States and abroad and (iv) laws that require the true, complete and accurate reporting of financial information or data. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Such misconduct also could involve the improper use of individually identifiable information, including, without limitation, information obtained in the course of clinical trials, creating fraudulent data in our preclinical studies or clinical trials or illegal misappropriation of drug product, which could result in regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from government investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. Additionally, we are subject to the risk that a person or government could allege such fraud or other misconduct, even if none occurred. If any such actions are instituted against us and we are not successful in defending ourselves or asserting our rights, those actions could result in significant civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participating in government-funded healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of noncompliance with these laws, contractual damages, reputational harm and the curtailment or restructuring of our operations, any of which could have a negative impact on our business, financial condition, results of operations and prospects.
If we engage in an acquisition, reorganization or business combination, we will incur a variety of risks potentially adversely affecting our business operations or our stockholders.
From time to time we have considered, and we will continue to consider in the future, strategic business initiatives intended to further the expansion and development of our business. These initiatives may include
acquiring businesses, technologies, or products or entering into a business combination with another company. If we pursue such a strategy, we could, among other things:
▪issue equity securities dilutive to our current stockholders' percentage ownership;
▪incur substantial debt straining our operations;
▪spend substantial operational, financial, and management resources to integrate new businesses, technologies, and products;
▪assume substantial actual or contingent liabilities;
▪reprioritize our development programs and even cease development and commercialization of our product candidates; or
▪merge with, or otherwise enter into a business combination with, another company in which our stockholders would receive cash and/or shares of the other company on terms certain of our stockholders may not deem desirable.
Although we intend to evaluate and consider acquisitions, reorganizations, and business combinations in the future, we have no agreements or understandings with respect to any acquisition, reorganization, or business combination at this time.
Security breaches, cyber-attacks or other disruptions or incidents could expose us to liability and affect our business and reputation.
We are increasingly dependent on our information technology systems and infrastructure for our business. We, our collaborators and our service providers collect, store, and transmit sensitive information including intellectual property, proprietary business information, clinical trial data and personal information in connection with our business operations. The secure maintenance of this information is critical to our operations and business strategy. Some of this information could be an attractive target of criminal attack by third parties with a wide range of motives and expertise, including organized criminal groups, "hacktivists," patient groups, disgruntled current or former employees, nation-state and nation-state supported actors and others. Cyber-attacks are of ever-increasing levels of sophistication, and despite our security measures, our information technology and infrastructure may be vulnerable to such attacks or may be breached, including due to employee error or malfeasance. We have implemented information security measures to protect our systems, proprietary information and sensitive data, including the personal information of clinical trial participants against the risk of inappropriate and unauthorized external use and disclosure and other types of compromise. However, despite these measures, and due to the ever changing information cyber-threat landscape, we cannot guarantee that these measures will be adequate to detect, prevent or mitigate security breaches and other incidents and we may be subject to data breaches through cyber-attacks, malicious code (such as viruses and worms), phishing attacks, social engineering schemes, and insider theft or misuse. Any such breach could compromise our networks and the information stored there could be accessed, modified, destroyed, publicly disclosed, lost or stolen. If our systems become compromised, we may not promptly discover the intrusion. Like other companies in our industry, we have experienced attacks to our data and systems, including malware and computer viruses. Any security breach of other incident, whether real or perceived, would cause us to lose product sales, and suffer reputational damage and loss of customer confidence. Such incidents could result in costs to respond to, investigate and remedy such incidents, notification obligations to affected individuals, government agencies, credit reporting agencies and other third parties, legal claims or proceedings, and liability under our contracts with other parties and federal and state laws that protect the privacy and security of personal information. If a security breach, cyber-attack, or other disruption is the result of state-sponsored activities, it may be considered an "act-of-war", potentially making us ineligible for reimbursement under our insurance policies covering such attacks. Any one of these events could cause our business to be materially harmed and our results of operations would be adversely impacted.
The occurrence of natural disasters, including a tornado, an earthquake, or fire, or any material failure, weakness, interruption, cyber-attack, security incident, war or any other catastrophic event, could disrupt our operations or the operations of third parties who provide vital support functions to us, which could have a material adverse effect on our business, results of operations, and financial condition.
We and the third-party service providers on which we depend for various support functions, such as data storage, are vulnerable to damage from catastrophic events, such as power loss, natural disasters, terrorism, physical theft, power loss, war, state-sponsored attacks, telecommunications failure and similar unforeseen events beyond our control, as well as from internal and external security breaches, malware and viruses, denial or degradation of service attacks, ransomware, cyber events and other disruptive problems. Such events could
severely disrupt our operations and have a material adverse effect on our business, results of operations, financial condition, and prospects.
If a natural disaster, power outage, security incident or other event occurred that prevented us from using all or a significant portion of our offices or other facilities, damaged critical infrastructure such as our data storage facilities, financial systems, or manufacturing resource planning and quality systems, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. The disaster recovery and business continuity plans we have in place currently are limited and are unlikely to prove adequate in the event of a serious disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which could have a material adverse effect on our business. In addition, the failure of our systems to operate effectively, maintenance problems, upgrading or transitioning to new platforms, or a breach in security could result in delays and reduce efficiency in our operations. Remediation of such problems could result in significant, unplanned capital investments.
Furthermore, parties in our supply chain may be operating from single sites, increasing their vulnerability to natural disasters or other sudden, unforeseen, and severe adverse events. If such an event were to affect our supply chain, it could have a material adverse effect on our business.
We are subject to numerous and varying data privacy and security laws, regulations and standards, and our failure to comply could result in penalties and reputational damage.
We are subject to domestic and foreign laws and regulations concerning data privacy, information security and the protection of personal information including health information. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing focus on privacy and data protection issues which may affect our business and is expected to increase our compliance costs and exposure to liability. In the United States, numerous federal and state laws and regulations, including state security breach notification laws, federal and state health information privacy laws (including HIPAA), and federal and state consumer protection laws, govern the collection, use, disclosure, and protection of personal information. Each of these laws is subject to varying interpretations by courts and government agencies, creating complex compliance issues for us. For example, the California Consumer Privacy Act (CCPA) went into effect January 1, 2020. The CCPA, among other things, imposes new data privacy obligations on covered companies and provides expanded privacy rights to California residents, including the right to access, delete and opt out of certain disclosures of their information. The CCPA provides for civil penalties for violations, as well as a private right of action with statutory damages for certain data breaches, which may increase the frequency and likelihood of data breach litigation. Although the law includes limited exceptions, including for "protected health information" maintained by a covered entity or business associate, such exceptions may not apply to all of our operations and processing activities. Further, the California Privacy Rights Act (CPRA), recently passed in California. The CPRA imposes additional data protection obligations on covered businesses, including additional consumer rights processes, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data. It also creates a new California data protection agency authorized to issue substantive regulations and could result in increased privacy and information security enforcement. The majority of the provisions will go into effect on January 1, 2023, and additional compliance investment and potential business process changes may be required. In addition, the CCPA has prompted a number of proposals for new federal and state privacy legislation that, if passed, could increase our potential liability, increase our compliance costs and adversely affect our business. If we fail to comply with applicable laws and regulations we could be subject to penalties or sanctions, including criminal penalties if we knowingly obtain or disclose individually identifiable health information in a manner that is not authorized or permitted by HIPAA or applicable state laws.
We are also or may become subject to rapidly evolving data protection laws, rules and regulations in foreign jurisdictions, including Canada, Australia, Brazil, Georgia and Europe. For example, the European Union General Data Protection Regulation (GDPR) governs certain collection and other processing activities involving personal data about individuals in the European Economic Area and the United Kingdom. Among other things, the GDPR imposes requirements regarding the security of personal data, the rights of data subjects to access and delete personal data, requires having lawful bases on which personal data can be processed and transferred outside of the European Economic Area, requires changes to informed consent practices, and requires more detailed notices for clinical trial participants and investigators. In addition, the GDPR imposes substantial fines for breaches and violations (up to the greater of €20 million or 4% of our annual global revenue). 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. Relatedly, following
the United Kingdom's withdrawal from the European Economic Area and the European Union, and the expiry of the transition period, companies will have to comply with the GDPR and the GDPR as incorporated into United Kingdom national law, the latter regime having the ability to separately fine up to the greater of £17.5 million or 4% of global turnover. The relationship between the United Kingdom and the European Union in relation to certain aspects of data protection law remains unclear, for example around how data can lawfully be transferred between each jurisdiction, which exposes us to further compliance risk.
Compliance with U.S. and foreign privacy and security laws, rules and regulations could require us to take on more onerous obligations in our contracts, require us to engage in costly compliance exercises, restrict our ability to collect, use and disclose data, or in some cases, impact our or our partners' or suppliers' ability to operate in certain jurisdictions. Each of these constantly evolving laws can be subject to varying interpretations. If we fail to comply with any such laws, rules or regulations, we may face government investigations and/or enforcement actions, fines, civil or criminal penalties, private litigation or adverse publicity that could adversely affect our business, financial condition and results of operations.
U.S. tax legislation and future changes to applicable U.S. tax laws and regulations may have a material adverse effect on our business, financial condition and results of operations.
Changes in laws and policy relating to taxes may have an adverse effect on our business, financial condition and results of operations. For example, the U.S. government enacted significant tax reform legislation in 2017, which, as modified by the CARES Act, contains, certain provisions which may adversely affect us. Changes include, but are not limited to, a federal corporate income tax rate decrease to 21% for tax years beginning after December 31, 2017, a reduction to the maximum deduction allowed for net operating losses generated in tax years after December 31, 2017, eliminating carrybacks of net operating losses for tax years beginning after December 31, 2020, providing for indefinite carryforwards for losses generated in tax years after December 31, 2017, imposing significant additional limitations on the deductibility of interest, allowing for the accelerated expensing of capital expenditures, and putting into effect the migration from a "worldwide" system of taxation to a largely territorial system. The legislation is unclear in many respects and may continue to be subject to potential amendments, technical corrections, interpretations and implementing regulations by the Treasury and Internal Revenue Service, any of which may mitigate or increase certain adverse effects of the legislation. In addition, it is unclear how these U.S. federal income tax changes will affect state and local taxation. Generally, future changes in applicable U.S. tax laws and regulations, or their interpretation and application could have an adverse effect on our business, financial condition and results of operations.
We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers. If we are not able to adequately prevent disclosure of trade secrets and other proprietary information, the value of our technology and products could be significantly diminished.
As is common in the biotechnology and pharmaceutical industries, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although we seek to protect our ownership of intellectual property rights by ensuring that our agreements with our employees, collaborators and other third parties with whom we do business include provisions requiring such parties to assign rights in inventions to us, we may be subject to claims that these employees, or we, have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. We may also be subject to claims that former employers or other third parties have an ownership interest in our patents. Litigation may be necessary to defend against these claims. There is no guarantee of success in defending these claims, and if we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, validity or enforceability of, or right to use, valuable intellectual property. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.
We rely on trade secrets to protect our proprietary technologies, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. We rely in part on confidentiality agreements with our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors to protect our trade secrets and other proprietary information. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover our trade secrets and proprietary information. For example, the FDA, as part of its Transparency Initiative, is currently considering whether to make additional information publicly available on a routine basis, including information that we may
consider to be trade secrets or other proprietary information, and it is not clear at the present time how the FDA's disclosure policies may change in the future, if at all. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position.
The laws of some foreign countries do not protect proprietary rights to the same extent as do the laws of the United States, and we may encounter significant problems in securing and defending our intellectual property rights outside the United States.
Many companies have encountered significant problems in protecting and defending intellectual property rights in certain countries. The legal systems of certain countries, particularly certain developing countries, do not always favor the enforcement of patents, trade secrets, and other intellectual property rights, particularly those relating to pharmaceutical products, which could make it difficult for us to stop infringement of our patents, misappropriation of our trade secrets, or marketing of competing products in violation of our proprietary rights. Proceedings to enforce our intellectual property rights in foreign countries could result in substantial costs, divert our efforts and attention from other aspects of our business, and put our patents in these territories at risk of being invalidated or interpreted narrowly, or our patent applications at risk of not being granted, and could provoke third parties to assert claims against us. We may not prevail in all legal or other proceedings that we may initiate and, if we were to prevail, the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.
