PART I

Item 1.    Business.

Overview

We are a biopharmaceutical company focused on delivering novel, transformational medicines with optimized pharmacology and pharmacokinetics to patients globally. Our internally developed pipeline includes multiple potentially first- or best-in-class assets with broad clinical utility.

Our most advanced investigational clinical programs include: etrasimod (APD334), being evaluated in a Phase 3 program for ulcerative colitis, or UC, a Phase 2b/3 program for Crohn’s disease, or CD, and a Phase 2 program in alopecia areata, or AA. We also plan to evaluate etrasimod in a Phase 3 program in atopic dermatitis, or AD, and a Phase 2b program for eosinophilic esophagitis, or EoE. Olorinab (APD371) is being evaluated for a broad range of visceral pain conditions associated with gastrointestinal diseases and is currently in a Phase 2b trial for treatment of abdominal pain associated with irritable bowel syndrome, or IBS. In addition, we plan to evaluate APD418, which is being developed for the treatment of acute heart failure, or AHF, in a Phase 2 trial. In January 2021, we announced a second compound in our cardiovascular therapeutic area, temanogrel, that we expect to advance into a Phase 2 proof of mechanism study in coronary microvascular obstruction, or cMVO.

We continue to leverage our two decades of world-class G-protein-coupled receptor, or GPCR, target discovery research to develop breakthrough drugs and ultimately deliver these to patients with unmet needs. Our long-term pipeline prospects include a collaboration with Beacon Discovery, Inc., or Beacon, across a broad range of immune-mediated inflammatory targets and compounds.

We have license agreements or collaborations with various companies, including:

 

United Therapeutics (ralinepag in a Phase 3 program for pulmonary arterial hypertension),

 

Everest Medicines Limited (etrasimod in a Phase 3 program for UC in Greater China and select countries in Asia),

 

Beacon Discovery (early research platform for GPCR targets), and

 

Boehringer Ingelheim International GmbH (undisclosed orphan GPCR program for central nervous system – preclinical).

In October 2020, we announced the launch and $56.0 million financing of Longboard Pharmaceuticals, Inc., or Longboard (formerly known as Arena Neuroscience, Inc.) which is expected to focus on developing novel central nervous system, or CNS, targeted assets discovered by our GPCR research engine. Longboard was previously a wholly owned subsidiary of Arena. As of the completion of Longboard’s Series A financing, our Longboard founder common stock and Series A preferred stock comprised approximately 33.4% of the outstanding shares of capital stock of Longboard. We have licensed certain development and worldwide commercialization rights to Longboard and are entitled to receive royalties on potential sales of LP352, LP143 and LP659, in the future.

Our Strategy

The primary elements of our strategy are:

 

Develop etrasimod – a modulator of the sphingosine 1-phosphate, or S1P, receptor intended for the treatment of a broad range of immune-mediated inflammatory diseases including gastrointestinal and dermatologic diseases;

 

Develop olorinab – an agonist of the cannabinoid receptor 2, or CB2, intended for the treatment of a range of visceral pain associated with gastrointestinal conditions;

 

Develop APD418 – a β3-AdrR antagonist and cardiac myotrope intended for AHF;

 

Develop temanogrel – a peripherally acting and selective 5HT2a inverse agonist intended for cMVO;

 

Progress a broad early-stage pipeline build with Beacon and consider other external opportunities with potential for transformational innovation in our disease areas of interest;  

 

Develop our pipeline by efficiently managing our cash and development timelines, which may include entering strategic agreements for certain clinical and preclinical programs;

 

Explore existing compounds in new indications and progress additional pipeline programs over time in select therapeutic areas; and

 

Prudently build a vibrant, sustainable, high-performing organization.

Pipeline of Development Programs

Below is a summary of our internally developed, proprietary portfolio:

Etrasimod Program

Etrasimod is a next-generation, oral, highly selective sphingosine 1-phosphate, or S1P, receptor modulator, discovered by Arena, designed to provide systemic and local cell modulation by selectively targeting S1P receptor subtypes 1, 4 and 5. S1P receptors have been demonstrated to be involved in the modulation of several biological responses, including lymphocyte trafficking from lymph nodes to the peripheral blood. By isolating subpopulations of lymphocytes in lymph nodes, fewer immune cells are available in the circulating blood to effect tissue damage. Etrasimod has therapeutic potential in immune-mediated inflammatory disease areas including gastroenterology and dermatology. We are currently evaluating etrasimod in ulcerative colitis, Crohn’s disease, eosinophilic esophagitis, atopic dermatitis, and alopecia areata.

Gastrointestinal Diseases

Inflammatory bowel diseases

Inflammatory bowel diseases, or IBD, like UC and CD are chronic life-long immune-mediated inflammatory conditions of the gastrointestinal tract that affect approximately 1.7 million patients in the United States, or US, alone. The prevalence of UC and CD in the US are currently estimated at approximately 0.9 million and 0.8 million patients, respectively. The prevalence of IBD in France, Germany, Italy and Spain collectively, or EU4, and the United Kingdom, is estimated at 1.3 million with approximately 0.7 million patients with UC and 0.6 million patients with CD. Both conditions represent a significant burden to patients, including hospitalization, surgery, and a longer-term risk of colon cancer, as well as impaired quality of life, economic productivity and social functioning. Additionally, Japan has an estimated prevalence of approximately 0.2 million IBD patients. In aggregate, there are approximately 3.2 million patients across the US, EU4, the United Kingdom, and Japan that are currently living with IBD.

UC is characterized by contiguous mucosal inflammation limited to the colon which involves the rectum in approximately 95% of cases and may extend to involve parts or all of the large intestine. In contrast, CD is characterized by full thickness inflammation that can occur anywhere in the gastrointestinal, or GI, tract but most typically involves the terminal ileum and colon; and causes fistulation and scarring. Symptoms for UC and CD can vary, depending on the location and severity of inflammation, but some of the most common are diarrhea, abdominal cramps, and rectal bleeding.

An important goal of therapy for IBD is durable remission while improving the patient’s quality of life. Although a number of therapies are approved for the treatment of IBD, they are often associated with an inability to induce or maintain remission, serious side effects, and complicated administration regimens. There is therefore an unmet medical need for novel oral agents with an enhanced risk-benefit profile and more convenient administration for the treatment of moderately to severely active IBD.

Eosinophilic Esophagitis

Eosinophilic esophagitis, or EoE, is a chronic, relapsing and remitting, immune mediated disease of the esophagus driven by an allergic Th2 T cell inflammatory profile. Histologically, EoE is characterized by the accumulation of eosinophils in the lining of the esophagus, a tissue that under normal conditions lacks these cells. In addition to eosinophils, CD4 and CD8 T cells, dendritic cells and mast cells increase in the tissue. The presence of these unwelcome inflammatory cells has been shown to have a direct effect on immune function and tissue damage. Both pediatric and adult populations can develop EoE, however, the disorder is most common in individuals between the ages of 20 and 40 years old. EoE also exhibits a strong hereditability pattern and predominance for males and for Caucasians, and principally in socioeconomically developed countries. EoE affects approximately 135,000 patients of all ages in the US and an estimated 132,000 patients in the EU4 and United Kingdom. There are no approved therapies in the US for the treatment of EoE. We believe that etrasimod may represent a significant opportunity to provide an effective treatment to EoE due to its potential to modulate the trafficking of multiple immune subsets.

Dermatologic Conditions

Atopic Dermatitis

Atopic dermatitis, or AD, is a chronic, inflammatory skin disorder characterized by dry skin, pruritus, and relapsing lesions. AD has a severe impact on quality of life, including potential occupational, social, and psychological impairments. The adult diagnosed prevalence is approximately 8.5 million patients in the US, and 6.5 million patients in the EU4 and United Kingdom. According to a recent survey with dermatologists in the US, 56% of dermatologists reported a high unmet need in atopic dermatitis.

Two new therapies have been marketed in the US since 2016, however these treatments have less desirable administration routes and are not effective in all patients. Therefore, we believe a significant unmet need remains for differentiated, safe, oral agents that are effective and have a favorable side effect profile. AD pathology is driven by a combination of impaired skin epithelial barriers, altered microbiota, and aberrant inflammation driven by activated immune cells, including skin-infiltrating T cells and dendritic cells, or DCs. Etrasimod may have the potential to reduce DC migration/activation (S1P receptor subtypes 1 and 4 mediated) and T cell infiltration (S1P receptor subtype 1 mediated) in the skin. These effects could reduce the T cell-mediated inflammation in the skin that underlies atopic dermatitis pathogenesis.

Alopecia Areata

Alopecia areata is a T-cell-mediated autoimmune skin disorder with unmet medical need that causes non-scarring patchy hair loss, most often on the scalp. The prevalence is approximately 2.9 million patients in the US and 2.2 million in the EU4 and United Kingdom.

The disease may be limited to 1 or more discrete, round or oval patches of hair loss the size of a coin on the scalp, or it may progress to full hair loss of the scalp (alopecia totalis) or the entire body (alopecia universalis). The course of disease is unpredictable, with spontaneous regrowth of hair occurring in 80% of patients within the first year, and sudden relapse at any given time. Patients with extensive disease (at least 50% total scalp hair loss) rarely have spontaneous hair regrowth. Patients with persistent moderate-to-severe AA also often suffer tremendous emotional and psychosocial distress and reduced quality of life as a result of their hair loss. Thus, psychosocial support and therapy is an important part of disease management, as this often-disfiguring disease can be psychosocially burdensome. The estimated lifetime risk of AA is 1.7% among the general population and represents the second most common form of human hair loss, second only to androgenetic alopecia. The current standard of care is injected corticosteroids which have limitations in terms of efficacy. Etrasimod may have the potential to reduce circulating CD4+ and CD8+ lymphocytes available to infiltrate the hair follicle which may decrease inflammation and restore hair growth.

Etrasimod Development

Inflammatory Bowel Disease

We are currently in a Phase 3 program in UC and a Phase 2b/3 program in CD. The first part of the CD program will evaluate approximately 50 participants in multiple doses.

In September 2020, we announced that the first participant had been dosed in ELEVATE UC 12, the second of two pivotal trials of 12 weeks and 52 weeks, respectively, that constitute our Phase 3 ELEVATE UC global registrational program to assess the safety and efficacy of once-daily etrasimod 2 mg in participants with moderately to severely active UC. The other pivotal trial in the ELEVATE UC program, ELEVATE UC 52, is expected to complete enrollment by the end of the first quarter of 2021, with the 52-week treatment period finishing in the first quarter of 2022, and we expect topline data from this trial by the end of the first quarter of

5


 

2022. We continue to monitor the impact of the COVID-19 pandemic on trial enrollment for both ELEVATE UC 52 and ELEVATE UC 12.

We plan to initiate a Phase 2 trial evaluating etrasimod for the potential treatment of moderately active UC, called GLADIATOR UC. This trial will be a multicenter, randomized, placebo-controlled 52-week trial to assess the safety and efficacy of once-daily etrasimod 2 mg in participants with moderately active UC. This trial is intended to evaluate etrasimod in a less severe patient population than ELEVATE UC, potentially broadening the patient population and demonstrating the potential use of a once-a-day oral therapy earlier in the treatment paradigm.

In September 2020, we also announced the addition of Sub-Study A to our Phase 2/3 CULTIVATE program evaluating etrasimod in CD. Sub-Study A is a Phase 2, multicenter, randomized 14-week trial, intended to provide supportive data for dose selection evaluating 2 mg and 3 mg etrasimod in subjects with moderately to severely active CD. The Phase 2/3 program also consists of a Phase 2b dose-ranging multicenter, randomized, double-blinded, placebo-controlled trial to assess the safety and efficacy of once-daily etrasimod in participants with moderately to severely active CD. The Phase 3 portion of the program will include two induction trials, with re-randomization of clinical responders into a single maintenance trial. The program is intended to provide an operationally seamless transition from Phase 2 to Phase 3. Our CULTIVATE Phase 2 dose-ranging trial of etrasimod in CD is ongoing and we are confirming options to help facilitate the availability of topline data for this trial in the second half of 2021. We have withdrawn previously announced overall program guidance for CULTIVATE based on the expected COVID-19 impact on trial execution, including site activation and participant enrollment.

In 2019, we announced positive results from a 34-week open-label extension, or OLE, of the Phase 2 OASIS trial of etrasimod for the treatment of UC. The trial enrolled 118 participants (84% of OASIS study completers), of which 22 completers also received 2 mg in OASIS, for a total of 46 weeks of treatment with etrasimod. Overall, etrasimod demonstrated durable, long-term clinical remission and was generally well tolerated in this trial. Adverse events in the OLE study were generally mild to moderate in severity and no new safety findings were noted. Impact on heart rate and atrioventricular, or AV, conduction was minimal throughout the study with no discontinuations from study related to bradycardia or AV block.

In 2018, we announced topline results from OASIS, a dose finding 12-week randomized, double-blind, placebo-controlled multinational Phase 2 clinical trial of etrasimod in moderate to severe UC. The aim of the trial was to investigate dose response and compare the active arm(s) to placebo. The trial evaluated the effects of etrasimod at 1 mg and 2 mg versus placebo on multiple efficacy measures including a three-component partial Mayo Clinic Score, clinical remission, clinical response, and endoscopic improvement in 156 participants. Etrasimod demonstrated a clear dose response and statistically significant improvements versus placebo in the primary, all secondary, and clinical remission endpoints at the 2 mg dose. There were fewer participants with serious adverse events, or SAEs, compared to placebo (0% in 2 mg, 5.8% in 1 mg and 11.1% in placebo). Impact on heart rate and AV conduction was low throughout the study with no discontinuations from study related to bradycardia or AV block. There were no increases in liver function tests compared to placebo and no reports of macular edema or pulmonary function test abnormalities. In this trial, etrasimod was well tolerated.

Eosinophilic Esophagitis

We are recruiting for a Phase 2b program for eosinophilic esophagitis and will enroll approximately 100 participants. Our Phase 2b VOYAGE trial of etrasimod is a randomized, double-blind, placebo-controlled trial, with a primary efficacy measurement at week 16 and a secondary efficacy analysis at week 24, to assess the safety and efficacy of 1 mg and 2 mg etrasimod in participants with EoE.

Atopic Dermatitis

In November 2020, we announced topline results from our ADVISE Phase 2b trial evaluating etrasimod in atopic dermatitis and our intention to advance etrasimod into a Phase 3 registrational program in AD. In the US approximately 60% of atopic dermatitis patients suffer from moderate to severe disease. Participants in the ADVISE trial were more representative of a moderate patient population (82.9% baseline vIGA 3). In the primary analysis, nearly one-third of participants in the 2 mg etrasimod group achieved clear or almost clear skin, as defined by the validated Investigator Global Assessment, or vIGA, which is the FDA endpoint for Phase 3 registration. The vIGA improvement was statistically significant as compared to placebo at 12 weeks. Across the Eczema Area and Severity Index, or EASI, a 75% reduction from baseline in EASI, or EASI-75, and peak change in pruritis, etrasimod 2 mg demonstrated early and statistically significant effect at week 4. Etrasimod did not meet the Phase 2b primary endpoint of EASI change from baseline at week 12 as compared to placebo.

Overall, the safety profile was consistent with previous trials of etrasimod including low first-dose heart rate effect with no titration, and no serious adverse events across the groups. In the etrasimod groups, there were no cases of venous thromboembolic

events, opportunistic or serious infections, macular edema, conjunctivitis, acne, or herpes zoster. Additionally, none of the other adverse events commonly associated with first-generation S1P receptor modulators were seen in this trial.

Between weeks 4-8, the trial was impacted by unwarranted dose interruption in 19% (n=9) of the etrasimod 2 mg group. Adjusting for this dose interruption, a post-hoc Completer Analysis, which included only those participants receiving full therapeutic exposure of etrasimod 2 mg, showed statistically significant effect on the EASI score compared to placebo (weeks 4 and 12), EASI-75 at week 4, vIGA at week 12 and pruritis through week 8. The Completer Analysis also showed no plateau of effect over the 12-week trial.

The analysis of the participant cohort with dose interruption showed diminished clinical effect upon withdrawal and a resumption of effect upon reinstatement of study drug consistent with the pharmacodynamics of etrasimod, which we believe further supports the clinical impact of etrasimod.

We have submitted additional data from the ADVISE trial at medical meetings and for publication in a peer-reviewed journal.

ADVISE was a Phase 2b multicenter, randomized, double-blinded, placebo-controlled trial to assess the safety and efficacy of once-daily etrasimod, the first oral S1P receptor modulator to be evaluated in subjects with moderate-to-severe atopic dermatitis. The primary endpoint measured was percent change in EASI from baseline to week 12, followed by a 4-week follow-up observation period. Secondary endpoints included the proportion of participants achieving EASI-75, proportion of participants with a vIGA 0 to 1, and percent change in peak pruritis. The ADVISE trial enrolled approximately 140 participants and was conducted in study sites across the United States, Canada and Australia. An open-label extension of the ADVISE trial is ongoing.

Alopecia Areata

We are currently recruiting a Phase 2 program in Alopecia Areata.

In September 2020, we announced that the first participant had been dosed in a Phase 2 trial evaluating etrasimod for the potential treatment of AA. We plan to enroll 36 participants in this Phase 2 randomized, placebo-controlled trial and will assess the safety and efficacy of once-daily etrasimod 2 mg in participants with moderate-to-severe AA. We expect to announce topline data for this trial in the second half of 2021.

Etrasimod Controlled-Release Formulation

In April 2020, we announced data from a Phase 1 clinical trial evaluating a controlled-release delivery profile for etrasimod.

The controlled-release profiles were designed to retain etrasimod's rapid onset of action while further improving its potentially best-in-class non-titrated, low intrinsic first-dose heart rate effect. A controlled-release formulation has the potential to deliver rapid life-cycle management and extend etrasimod's intellectual property portfolio.

Based on the results, we have initiated a product development program with initial results expected in 2021.

Prior Development

In January 2015, we announced top-line results from a Phase 1b multiple-ascending dose clinical trial for etrasimod. In this trial, etrasimod demonstrated a dose-dependent effect on lymphocyte count lowering in blood, with mean decreases from baseline of up to 69%. Lymphocyte counts, on average, recovered to baseline within one week of conclusion of dosing. There was a modest impact on heart rate, but none of the changes were classified by the investigator as clinically significant. There were also no findings with respect to pulmonary function or liver enzyme tests that were classified by the investigator as clinically significant. The most common treatment-emergent adverse events were mild or moderate contact dermatitis, headache, constipation and diarrhea, with none being clearly drug related. There were no discontinuations for adverse events, and no serious adverse events were observed.

The randomized, double-blind, placebo-controlled Phase 1b clinical trial evaluated the safety, tolerability, pharmacodynamics and pharmacokinetics of multiple-ascending doses of etrasimod. In five different dosing cohorts, 50 healthy volunteers received etrasimod and 10 healthy volunteers received placebo for 21 days.

Prior to commencing the Phase 1b multiple-ascending dose clinical trial for etrasimod, we completed a Phase 1 single-ascending dose clinical trial of the compound. This randomized, double-blind and placebo-controlled trial evaluated the safety, tolerability and pharmacokinetics of single-ascending doses of etrasimod in 40 healthy adult volunteers. In the trial, etrasimod demonstrated favorable pharmacokinetic and pharmacodynamic effects, a dose-responsive reduction in blood lymphocyte count and a slowing of heart rate that appears comparable to other S1P receptor modulators. The terminal half-life was approximately 35 hours.

Etrasimod Intellectual Property

As of February 5, 2021, we owned issued patents that cover compositions of matter for etrasimod and related compounds, and methods of treatment utilizing etrasimod and related compounds, in 61 jurisdictions, including the United States, China, Japan, Germany, France, Italy, the United Kingdom, Spain, Canada, India, Russia, South Korea and Australia, and had an application pending in one other jurisdiction (Brazil). The earliest priority date for the patents on etrasimod is 2008. The terms of these patents are capable of continuing into 2029 in most jurisdictions without taking into account any patent term adjustment or extension regimes of any country or any additional term of exclusivity we might obtain by virtue of the later filed patent applications.

Olorinab Program

Olorinab, a potentially first-in-class, orally available, potent, peripherally acting, highly selective, full agonist of the CB2 receptor, is an internally discovered investigational drug candidate we are exploring for the treatment of visceral pain, specifically abdominal pain in patients with irritable bowel syndrome.

Visceral pain is defined as pain that originates within muscle, pleura, connective tissue, nervous system or solid organs within the abdomen or peritoneum. It is distinct from somatic or neuropathic pain, and is perceived as stretching, pulling and distention, rather than by cutting, crushing, or burning more commonly associated with neuropathic pain. Visceral pain is one of the most common types of pain and may be caused by a diverse set of organic causes, such as inflammation (e.g., IBD, including CD and UC, pancreatitis, prostatitis, and vaginitis), obstruction (e.g., bowel obstruction, and nephrolithiasis), ischemia, and malignancy, among others. Visceral pain may also be caused by functional disorders such as interstitial cystitis, dyspepsia, IBS, and vulvodynia.

There are approximately 18 million patients in the US with IBS, with 78% reporting frequently recurring or continuous abdominal pain. Common treatments for visceral pain range from non-invasive, conservative approaches (e.g., physical therapy or acupuncture), to pharmacologic (e.g., tricyclic antidepressants acting as neurotransmitter reuptake inhibitors). Analgesics, such as opioids, can adversely affect GI function. Other commonly prescribed analgesics are often not potent enough and may lead to other GI side effects such as bleeding. Treatments such as linaclotide for IBS with predominant constipation or rifaximin for IBS with predominant diarrhea improve abdominal pain as well as abnormal bowel habits, however, no visceral-specific analgesics are currently available.

The CB2 receptor is expressed in the GI nervous system, and in many tissues and organs of the abdomen. CB2 receptors are found on immune cells but also on microglia, terminal neurons, dorsal root ganglia, and on visceral sensory neurons. We believe selectively targeting the CB2 receptor may provide therapeutic benefit for visceral pain without the potential for dependence, abuse, and GI and cardiovascular side effects associated with opiates or nonsteroidal anti-inflammatory drugs, or NSAIDs, which are among the most common pain relievers. In addition to analgesic effects, olorinab may have anti-inflammatory properties.

Olorinab is designed to be a peripherally acting and selective CB2 receptor agonist and is intended to provide pain relief without the unwanted side effects associated with CB1 receptor activation.

Olorinab Development

In October 2020, we announced that we completed full enrollment of our Phase 2b CAPTIVATE trial evaluating olorinab for the potential treatment of abdominal pain in IBS. CAPTIVATE is a Phase 2, 4-arm multi-center, randomized, double-blind, placebo-controlled, 12-week trial to assess the safety and efficacy of olorinab administered three times daily in 273 participants. In CAPTIVATE participants were randomized to placebo, 10 mg, 25 mg or 50 mg. We expect to announce topline data for this trial in the first quarter of 2021.

In 2018, we announced positive topline results from our Phase 2a trial of olorinab in development for the treatment of pain associated with CD. This exploratory study was an open‑label investigation to evaluate safety and tolerability of olorinab in this patient population and to gain initial insights into its efficacy via a pain visual analog scale, or VAS. Fourteen participants were enrolled into two cohorts at 25 mg and 100 mg administered three times daily for up to eight weeks. Reductions in pain were seen within the first week of treatment and statistically significant improvement from baseline in Average Abdominal Pain Score, or AAPS, at weeks four and eight. In this trial, olorinab appeared generally well tolerated with no clinically significant changes in heart rate or blood pressure, no psychotropic effects, and no discontinuations due to adverse events.

In April 2016, we announced favorable results from a Phase 1b multiple-ascending dose clinical trial of olorinab. This randomized, double-blind, placebo-controlled Phase 1b clinical trial enrolled 36 healthy adults to evaluate the safety, tolerability and pharmacokinetics of multiple-ascending doses of olorinab. Cohorts of 12 subjects (nine active, three placebo) were administered doses of 50 mg, 100 mg, or 200 mg of olorinab or placebo three times daily for 10 days and, in connection with the pharmacokinetic evaluation, one time on the 11th day. The most common adverse events were headache and nausea. All adverse events were classified as mild, and there were no serious adverse events reported. There was one discontinuation in the high-dose group due to an adverse

8


 

event of mild thirst and somnolence. Reductions in blood pressure and heart rate were observed, but none were symptomatic or resulted in an adverse event. Drug levels at all doses tested in the trial, including the lowest dose, were well above those believed to be needed to stimulate the CB2 receptor.

In April 2015, we announced favorable top-line results from a Phase 1 single-ascending dose clinical trial of olorinab. The randomized, double-blind and placebo-controlled trial enrolled 56 healthy adults to evaluate the safety, tolerability and pharmacokinetics of single-ascending doses of olorinab. Dose-responsive exposure was observed over the explored dose range of 10-400 mg with good tolerability at all doses administered.

Olorinab Intellectual Property

As of February 5, 2021, we owned issued patents covering compositions of matter for olorinab and related compounds, and methods of treatment utilizing olorinab and related compounds, in 23 jurisdictions, including the United States, China, Japan, Canada, India, Russia, South Korea and Australia, and we had applications pending in 8 other jurisdictions, of which the ones with the largest pharmaceutical markets were Europe, Venezuela, and Brazil. The earliest priority date for the patents on olorinab is 2009. The terms of these patents are capable of continuing into 2030 in most jurisdictions without taking into account any patent term adjustment or extension regimes of any country or any additional term of exclusivity we might obtain by virtue of the later filed patent applications.

APD418 Program

APD418 is a potential first-in-class β3-adrenergic receptor (AdrR) antagonist and cardiac myotrope designed to regulate myofilament calcium sensitivity in order to improve contractility without inducing the serious adverse events associated with currently available inotropes. APD418 is in early-stage clinical development for patients with AHF.

 

AHF is broadly defined as a rapid onset of new or worsening signs and symptoms of HF. It is a potentially life-threatening condition, requiring hospitalization, and emergency treatment is aimed predominantly at managing fluid overload and achieving hemodynamic stability. In most cases, hospitalization for AHF results when the neurohormonal compensatory mechanisms, which act to maintain hemodynamic stability in chronic heart failure, are inadequate.

 

Management of AHF is focused on treating clinical conditions and precipitating factors, immediate stabilization, and symptom relief. Most patients presenting to the emergency department with AHF are congested and have normal to high blood pressures. Diuretics are first line therapy to treat volume overload including congestion; vasodilators are also used as first line therapy for symptom relief in normotensive and hypertensive patients who fail to respond adequately to diuretics. Unfortunately, neither diuretics nor vasodilators have been associated with improved survival.

 

For patients presenting as hypotensive, who are at the highest risk of mortality, and patients who fail to adequately respond to initial therapy, treatment options are particularly limited and may require the use of inotropic agents. These agents aim to increase cardiac contractility and restore hemodynamic status via stimulation of the myocardial β1-AdrR, but they are associated with significant risk of unwanted hemodynamic effects, arrhythmias, and pathway dependent cardiotoxicity, leading to adverse outcomes and increased mortality.

 

Arena is developing APD418, an internally discovered and developed investigational drug candidate, to address the significant unmet need in AHF.

APD418 Development

In November 2020, we announced the completion of a first-in-human Phase 1 safety and tolerability trial of APD418 in AHF. The trial found APD418 was generally well tolerated. The FDA has granted us Fast Track designation for development of APD418 in AHF. A Phase 2 proof of mechanism is planned to initiate in the first half of 2021.

APD418 Intellectual Property

As of February 5, 2021, we owned issued patents covering compositions of matter for APD418 and related compounds, and methods of treatment utilizing APD418 and related compounds, in the United States, Japan and one other country, and we had applications pending in 40 other jurisdictions, of which the ones with the largest pharmaceutical markets were Europe and China. The earliest priority date for the patents on APD418 is 2016. The terms of these patents are capable of continuing into 2037 without taking into account any patent term extension.

Temanogrel Program

Temanogrel is a peripherally acting and selective 5HT2a inverse agonist designed to inhibit serotonin (5-HT)-mediated amplification of platelet aggregation and vasoconstriction.

A significant proportion of patients undergoing percutaneous coronary intervention, or PCI, for treatment of acute coronary syndrome, or ACS, fail to achieve full myocardial or microcirculatory reperfusion despite resolution of the epicardial coronary occlusion. This condition is referred to as cMVO and has been reported in approximately 40% to 60% patients undergoing PCI for ST-elevation myocardial infraction, or STEMI, and approximately 30% patients undergoing PCI for non-ST-elevation myocardial infarction, or NSTEMI, with the greatest incidence in high-risk NSTEMI patients. Importantly, the presence of cMVO post-PCI has been associated with worse clinical outcomes, including mortality and hospitalization for heart failure, related to suboptimal cardiac function and recovery in the days and months following the PCI procedure.

During PCI, platelets become activated following rupture of the atherosclerotic plaque, which can be either procedure-induced or occur spontaneously. Upon activation, platelets release 5-HT in substantial quantities. Serotonin acts on 5-HT2A receptors on platelets and smooth muscle cells, resulting in amplification of platelet aggregation and vasoconstriction, both of which may detrimentally affect the microcirculation. We believe blocking these 5-HT-mediated effects with temanogrel during and following PCI for STEMI and NSTEMI may prevent or minimize the development of cMVO and facilitate cardiac functional recovery, resulting in improved clinical outcomes.

Temanogrel Development

Arena is developing temanogrel, an internally discovered investigational drug candidate, to address the significant unmet need in cMVO.

In January 2021 at the JP Morgan Healthcare Conference, we announced that we will be conducting a Phase 2 proof of mechanism study for the treatment of coronary microvascular obstruction, or cMVO, and that we have completed four Phase 1 studies with the oral formulation and one Phase 1 study with the IV formulation of temanogrel. The FDA has granted us Fast Track designation for development of temanogrel for cMVO. A Phase 2 proof of mechanism study in cMVO is planned to initiate in the first half of 2021.

Temanogrel Intellectual Property

As of February 5, 2021, we owned issued patents that cover compositions of matter for temanogrel and related compounds, and methods of treatment utilizing temanogrel and related compounds, in 9 jurisdictions, including the United States, Japan, Germany, France, Italy, the United Kingdom, and Spain. The earliest priority date for the patents on etrasimod is 2004. The terms of these patents are capable of continuing into 2025 in most jurisdictions without taking into account any patent term adjustment or extension regimes of any country or any additional term of exclusivity we might obtain by virtue of the later filed patent applications.

Additional Internal Preclinical and Clinical Programs

In January 2020, we entered an agreement with Beacon Discovery for the development of multiple novel, early stage, oral autoimmune programs. The multiple G-protein-coupled receptor, or GPCR, targets in this collaboration with Beacon Discovery and their associated chemistry represent the next generation of oral compounds which, if successfully developed and approved, may transform the way autoimmune diseases are approached and treated. This collaboration includes both novel and validated targets and compounds.

We have additional assets, including other 5-HT2A modulators, which are either in or being evaluated for future clinical and preclinical development. We are also evaluating additional delivery forms of the products in our pipeline to extend clinical utility or improve the product profile.

Collaborations and License Agreements

We have strategic collaborations and licenses with pharmaceutical companies, including United Therapeutics, Everest Medicines Limited, or Everest, Boehringer Ingelheim International GmbH, or Boehringer Ingelheim, Beacon, and Eisai.

United Therapeutics License Agreement

In November 2018, we entered into a collaboration and license agreement with United Therapeutics. Under the United Therapeutics Agreement, we granted United Therapeutics an exclusive, worldwide, royalty-bearing license to develop, manufacture and commercialize ralinepag. This transaction was completed in January 2019. At the closing of the transaction, we transferred to United Therapeutics certain other assets relating to ralinepag, including, among others, related domain names and trademarks, permits,

10


 

certain contracts, inventory, regulatory documentation, IND, and non-clinical, pre-clinical and clinical trial data. United Therapeutics has agreed to assume certain limited liabilities, including, among others, all post-closing obligations under assumed contracts and the IND. United Therapeutics is responsible for all development, manufacture and commercialization of the licensed products globally.

Upon the closing of this transaction, in January 2019, we received an upfront payment of $800.0 million. We are eligible to receive a payment of $150.0 million upon first marketing approval of ralinepag in a major non-US market, and a payment of $250.0 million upon US marketing approval of an inhaled formulation of ralinepag. In addition, we are entitled to receive low double-digit, tiered royalties on net sales of ralinepag products, subject to certain adjustments for third-party license payments.

The United Therapeutics Agreement contains various representations and warranties of Arena and United Therapeutics, and various covenants of the parties, including covenants to cooperate in seeking regulatory approvals, as well as our agreement not to compete, during the period in which royalties are payable (or during the five-year period following the closing if we are subject to a change of control transaction) in the development of a prostacyclin to treat pulmonary hypertension.

Ralinepag Program

Ralinepag is in a Phase 3 program for pulmonary arterial hypertension, or PAH. Ralinepag is a next-generation potent, highly selective oral IP receptor agonist intended for the treatment of PAH. Ralinepag was designed by us to deliver intravenous prostacyclin-like potency and pharmacokinetics in an oral tablet. In non-clinical experiments, ralinepag demonstrated potentially best-in-class activation of the IP receptor resulting in vasodilation, inhibition of smooth muscle cell proliferation and inhibition of platelet aggregation. Additionally, early-stage studies of ralinepag pharmacokinetics in humans revealed an approximately 24-hour half-life and a low peak-to-trough ratio supporting therapeutic blood levels with once daily dosing.

Ralinepag was granted orphan drug status for the treatment of PAH by the US Food and Drug Administration, or FDA, in September 2014, and by the European Medicines Agency in January 2019.

PAH is a progressive, life-threatening disorder characterized by increased pressure in the pulmonary arteries that carry blood from the heart to the lungs. PAH occurs when the pulmonary arteries thicken or grow rigid. This makes blood flow more difficult. The heart must work harder to push blood through the arteries, and the arteries are unable to carry adequate blood to the lungs. The increased pressure strains the heart, which can limit physical activity, result in heart failure and reduce life expectancy. PAH will continue to worsen over time, even with proper treatment. Based on data from the Registry to EValuate Early And Long-term PAH disease management, or REVEAL, of patients in the US, there is an estimated five-year survival rate of 57% from diagnosis.

PAH involves several interrelated mechanisms, with prostacyclin and thromboxane A2 playing a major role in maintaining pulmonary vascular tone through their balanced activity. Prostacyclin, released by endothelial cells, promotes vasodilation and inhibits platelet aggregation. Prostacyclin also has antiproliferative effects on vascular smooth muscle. Despite treatment guidelines, targeting the prostacyclin pathway has been primarily reserved for patients with advanced disease due to limitations of currently available options including parenteral prostacyclins which are the only PAH treatment that have demonstrated a mortality benefit.

Everest Collaboration

In December 2017, we entered into a Collaboration and License Agreement, or the Everest Agreement, with Everest regarding the development and commercialization of ralinepag and etrasimod in China, Taiwan, Hong Kong, Macau and South Korea, or the Everest Territories. In January 2019, we and Everest amended the Everest Agreement by entering into two separate agreements, one for each of ralinepag and etrasimod, with the terms for each program that are substantially the same as in the original Everest Agreement. Under the United Therapeutics Agreement, we assigned the separate Everest Agreement related to ralinepag to United Therapeutics.

Under the separate Everest Agreement related to etrasimod, we granted Everest an exclusive, royalty-bearing license to develop, manufacture and commercialize etrasimod (in oral formulations only), in the Everest Territories.

Everest is responsible for all development, manufacture and commercialization of the licensed products in the Everest Territories, and may participate in the portion of our global clinical trials that is conducted in the Everest Territories.

We are eligible to receive development, regulatory and commercial milestone payments from Everest, as well as tiered royalties on net sales ranging from the high single digits to low double digits. Following an initial royalty term, we are eligible to receive a lower trademark royalty if Everest continues to use our licensed product-related trademarks.

In the fourth quarter of 2018, the National Medical Products Administration of China, formerly known as the China Food and Drug Administration, or CFDA, accepted the initial clinical trial applications for an oral formulation of ralinepag and for etrasimod. Subsequently, in the fourth quarter of 2019, Everest announced that the first subject has been dosed in a Phase 3 trial evaluating etrasimod in development for the treatment of UC in Greater China and South Korea. This Phase 3 trial is ongoing.

Boehringer Ingelheim Collaboration

In 2015, we entered into an exclusive agreement with Boehringer Ingelheim, to conduct joint research to identify drug candidates targeting a GPCR that belongs to a group of orphan central nervous system, or CNS, receptors. An “orphan receptor” is structurally related to a family of proteins that are known to act as functional cell-surface receptors but whose ligand has not yet been identified. A lead molecule is currently in preclinical development.

In the past, we contracted with Beacon to perform our research obligations under the Boehringer Ingelheim collaboration. In exchange, we agreed to share limited near-term milestones with Beacon as well as the full-time equivalent funding paid to us by Boehringer Ingelheim. We have retained the longer-term success milestones and all royalties.

Beacon Discovery Agreements

In January 2020, we entered into a new multi-year strategic Collaboration and License Agreement with Beacon, aimed at building novel medicines across a range of GPCR targets believed to play a role in immune and inflammatory diseases. Under the terms of this agreement, Beacon is responsible for early drug discovery activities and Arena will be responsible for any potential future development and, ultimately, commercialization activities. We are required to pay to Beacon research initiation fees, make quarterly research funding payments for the duration of Beacon’s research activities as well as research, development and regulatory milestone payments. We are also obligated to pay Beacon tiered royalties on net sales of low single digits levels.

Beginning in September 2016, we entered into a series of agreements with Beacon.

In 2016, we entered into a License and Collaboration Agreement with Beacon, pursuant to which we granted Beacon a non-exclusive, non-assignable and non-sublicensable license to certain database information relating to compounds, receptors and pharmacology, and transferred certain equipment to Beacon. Beacon will seek to engage global partners to facilitate discovery and development. Beacon has agreed to assign to us any intellectual property relating to our existing research and development programs developed in the course of performing research for us and grant us a non-exclusive license to any intellectual property developed outside the course of performing work for us that is reasonably necessary or useful for developing or commercializing the products under our research and development programs. We are also entitled to rights of negotiation and rights of first refusal to potentially obtain licenses to certain compounds discovered and developed by Beacon. In addition, we are entitled to receive (i) a percentage of any revenue received by Beacon on or after the second anniversary of the effective date of the agreement from any third party pursuant to a third-party license, including upfront payments, milestone payments and royalties; (ii) single-digit royalties on the aggregate net sales of any related products sold by Beacon and its affiliates; and (iii) in the event that Beacon is sold, a percentage of the consideration for such sale transaction.

In 2016, we also entered into a Master Services Agreement with Beacon, pursuant to which Beacon performs certain other research services for us relating to our proprietary pipeline.

Beacon was founded and is owned by several of our former employees.

Eisai Agreement

In December 2016, we entered into a Transaction Agreement with Eisai regarding lorcaserin. Pursuant to the Transaction Agreement, we granted Eisai an exclusive, royalty-bearing license, or transferred intellectual property, to develop, manufacture and commercialize lorcaserin in all countries and territories of the world. Under the Transaction Agreement we are entitled to receive tiered royalty payments starting at 9.5% on net sales of lorcaserin.

Lorcaserin was approved for marketing in the U.S., and in certain other territories, for the indication of weight management. On February 13, 2020, the FDA issued a drug safety communication announcing that it requested Eisai voluntarily withdraw lorcaserin from the U.S. market based on the FDA’s analysis of data from the Cardiovascular and Metabolic Effects of Lorcaserin in Overweight and Obese Patients – Thrombolysis in Myocardial Infarction 61 (CAMELLIA-TIMI 61) study, and that Eisai has submitted a request to voluntarily withdraw lorcaserin from the U.S. market. On September 30, 2020, Eisai announced that, after consulting with the FDA, it is continuing the lorcaserin expanded access program and has initiated a Phase 3 clinical study of lorcaserin in patients with Dravet syndrome, a severe type of epilepsy characterized by prolonged seizures that begin in the first year of life.  

12


 

In October 2020, we entered into a Royalty Purchase Agreement with Longboard pursuant to which Longboard purchased from us the right to receive all milestone payments, royalties, interest and other payments relating to net sales of lorcaserin owed or otherwise payable by Eisai.

We believe that Eisai is solely responsible for any expenses and losses associated with product liability claims, except we and Eisai share 50% of losses for any alleged defective manufacturing of lorcaserin that was manufactured by us prior to entering into the Transaction Agreement.  

Intellectual Property

Our success depends in large part on our ability to protect our compounds and information, and to operate without infringing the proprietary rights of third parties. We rely on a combination of patent, trade secret, copyright, and trademark laws, as well as confidentiality, licensing and other agreements, to establish and protect our proprietary rights. We seek patent protection for our key inventions, including drug candidates we identify, routes for chemical synthesis, pharmaceutical formulations and methods of treatment.

There is no assurance that any of our patent applications will issue, or that any of the patents will be enforceable or will cover a drug or other commercially significant product or method. In addition, we regularly review our patent portfolio to identify patents and patent applications for potential abandonment that we deem to have relatively low value to our ongoing business operations. There is also no assurance that we will correctly identify which of our patents and patent applications should be maintained and which should be abandoned. The term of most of our current patents commenced, and most of our future patents, if any, will commence, on the date of issuance and terminate 20 years from the earliest effective filing date of the patent application. Because any marketing and regulatory approval for a drug often occurs several years after the related patent application is filed, the resulting exclusivity afforded by any patent on our drug candidates will likely be substantially less than 20 years.

In the United States, patent term adjustment is available for certain delays in patent office proceedings. In addition, under the Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch-Waxman Act, the term of a patent that covers an FDA-approved drug may be eligible for patent term extension, or PTE. PTE permits patent term restoration of a US patent as compensation for the patent term lost during product development and the FDA regulatory review process. The Hatch-Waxman Act permits a PTE of up to five years beyond the expiration of the patent. This period is generally one-half the time between the effective date of an Investigational New Drug, or IND (falling after issuance of the patent), and the submission date of an NDA, plus the time between the submission date of an NDA and the approval of that application, provided the sponsor acted with diligence. A PTE cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval and only one patent applicable to an approved drug may be extended. The application for PTE is subject to approval by the US Patent and Trademark Office in conjunction with the FDA.

Outside of the United States, similar provisions may be available in the European Union, Japan, South Korea and some other jurisdictions to extend the term of a patent that covers an approved drug. The length of any such extension may vary by country. Our European patents may be eligible for supplemental protection certificates of up to five years in one or more countries.

Due to the specific requirements for obtaining these extensions, there is no assurance that our patents will be afforded extensions even if we encounter significant delays in patent office proceedings or marketing and regulatory approval.

In addition to patent protection, we rely on trade secrets, proprietary know-how and continuing technological advances to develop and maintain our competitive position. To maintain the confidentiality of our trade secrets and proprietary information, all of our employees are required to enter into and adhere to an employee confidentiality and invention assignment agreement, and invention disclosure procedures as a condition of employment. Additionally, our employee confidentiality and invention assignment agreements require that our employees not bring to us, or use without proper authorization, any third-party proprietary technology. We also generally require our consultants and collaborators that have access to proprietary property and information to execute confidentiality and invention rights agreements in our favor. While such arrangements are intended to enable us to better control the use and disclosure of our proprietary property and provide for our ownership of proprietary technology developed on our behalf, they may not provide us with meaningful protection for such property and technology in the event of unauthorized use or disclosure.

Competition

The biotechnology and pharmaceutical industries are highly competitive and are subject to rapid and significant change. We face significant competition from many organizations with drugs or drug candidates that do or may compete with drug candidates we are developing. We may not be able to compete successfully against these organizations, which include many large, well-financed and experienced pharmaceutical and biotechnology companies, as well as academic and research institutions and government agencies.

13


 

Developments by others may render our drug candidates obsolete or noncompetitive, and we or our collaborators may not be successful in developing either first- or best-in-class drugs.

Etrasimod is currently in development for the treatment of IBD, including in a Phase 3 program in UC and in a Phase 2b/3 program in CD. If approved in IBD, etrasimod would compete with generic drugs, branded oral agents, biologics and biosimilars. There are multiple FDA-approved products for treatment of moderate-to-severe IBD. Many of these products are biologics and include but are not limited to adalimumab by AbbVie, vedolizumab by an affiliate of Takeda Pharmaceuticals, and infliximab and ustekinumab by Janssen Biotech. Additionally, there are approved biosimilar agents to infliximab. There are also approved oral agents, including tofacitinib by Pfizer, as well as multiple oral agents in development. Ozanimod, by Bristol Myers Squibb, or BMS, is an S1P receptor modulator that is approved for use in multiple sclerosis and has completed P3 trials in UC. There are also JAK inhibitors in development, including but not limited to filgotinib by Gilead Sciences and Galapagos, and upadacitinib by AbbVie. There are also oral generic agents such as mesalamine and methotrexate used in the treatment of IBD.

Etrasimod has completed a Phase 2 study in AD and we intend to advance into a Phase 3 program for etrasimod in AD. If approved for that indication, etrasimod would compete with generic topical agents, branded topical agents, oral agents, and biologics. Currently AD patients are treated with generic topical steroids, generic topical calcineurin inhibitors, oral generic agents including cyclosporine and methotrexate, and a branded biologic agent, dupilumab, from Regeneron and Sanofi, which was approved in 2017. There are a number of topical treatments, oral agents, and biologic agents in development for AD. Topical agents may have different indications and limitations of use. Three oral agents have completed Phase 3 trials in AD and include baricitinib by Eli Lilly, abrocitinb by Pfizer, and upadacitinib by AbbVie. Baricitinib is approved in the EU and Japan for moderate to severe atopic dermatitis. Physicians may also use agents such as tofacitinib off-label in the treatment of AD. There are also biologic agents in development for AD including but not limited to IL-13 inhibitors tralokinumab by Leo Pharma and lebrikizumab by Eli Lilly. This list does not include all topical, oral, or biologic agents in development.

Etrasimod is currently in Phase 2 programs for the treatment of EoE and AA. If approved for EoE, etrasimod would compete with generic oral steroids, branded oral steroids, generic and branded proton pump inhibitors, and biologics. If approved for AA, etrasimod would compete with generic topical agents, branded topical agents, oral agents, and biologics.

Olorinab is being studied in IBS-C and IBS-D pain. Currently, there are approved agents and off-label medications used to treat pain associated with IBS-C and IBS-D. Linaclotide by Ironwood Pharmaceuticals is indicated for IBS-C. Eluxadoline by AbbVie is indicated for IBS-D. Generic oral molecules are used off label in IBS-C and IBS-D, including tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitors, or SNRIs, and opioids.

APD418 is in development for AHF. There are currently no approved products to improve outcomes in AHF patients. A number of agents are used off-label, including, inotropic agents, loop diuretics, nitrate vasodilators, PDE3 inhibitors, and calcium sensitizers. Other agents are in development—for example, BMS is developing cimlanod (BMS-986231) in a Phase 2 study and Lee’s Pharma is developing istaroxime, a positive inotropic agent.

Temanogrel is in development for prevention of cMVO in the setting of PCI. A number of drugs are used off-label to manage these patients, including direct thrombin inhibitors, glycoprotein IIb/IIIa inhibitors, and calcium channel blockers. There is one agent in Phase 2 development, revacept, by AdvanceCor, with a mechanism of action of platelet membrane glycoprotein VI inhibition.

Many of our existing and potential competitors have substantially greater drug development capabilities and financial, scientific and marketing resources than we do. Additional consolidation in the pharmaceutical industry may result in even more resources being concentrated with our competitors. As a result, our competitors may be able to devote greater resources than we can to the research, development, marketing and promotion of therapeutic products or drug discovery techniques, or to adapt more readily to technological advances than we can. Accordingly, our competitors may succeed in obtaining patent protection, receiving regulatory approval or commercializing drugs before we do.

We may rely on collaborators for support of development programs and for the manufacturing and marketing of drug candidates. Such collaborators may be conducting multiple drug development efforts within the same disease areas that are the subject of their agreements with us, which may negatively impact the development of drugs that are subject to our agreements. In addition, we face and will continue to face intense competition from other companies for such collaboration arrangements, and technological and other developments by others may make it more difficult for us to establish such relationships.

Government Regulation

We and our collaborators are subject to significant governmental regulation. The FDA and comparable regulatory agencies in state and local jurisdictions and in foreign countries impose substantial requirements upon the preclinical and clinical development, pre-market approval, manufacture, import, export, marketing and distribution of pharmaceutical products. These agencies and other

14


 

regulatory agencies regulate research and development activities and the testing, approval, manufacture, quality control, safety, effectiveness, labeling, storage, tracking, recordkeeping, advertising, pricing and promotion of drug candidates and commercialized drugs. Failure to comply with applicable FDA or other regulatory requirements may result in inspectional notices of violation, warning letters, civil or criminal penalties, suspension or delays in clinical development, recall or seizure of products, partial or total suspension of production, withdrawal of a product from the market or other negative consequences.

In the United States

In the United States, the FDA regulates drug products under the Federal Food, Drug, and Cosmetic Act, or FD&C Act, and its implementing regulations. The process required by the FDA before drug candidates may be marketed in the United States generally involves the following:

 

completion of extensive preclinical laboratory tests and preclinical animal studies, many of which are required to be performed in accordance with the FDA’s Good Laboratory Practice, or GLP, regulations;

 

submission to the FDA of an IND, which must become effective before human clinical trials may begin and be updated annually;

 

performance of adequate and well-controlled human clinical trials, performed in accordance with the FDA’s Good Clinical Practice, or GCP, regulations, to establish the safety and efficacy of the drug candidate for each proposed indication;

 

submission to the FDA of a New Drug Application, or NDA, after completion of adequate and well-controlled human clinical trials, generally accompanied by payment of a substantial user fee to the FDA;

 

a determination by the FDA within 60 days of its receipt of the NDA to file the NDA for review;

 

satisfactory completion of an FDA pre-approval inspection of the manufacturing facilities at which the active pharmaceutical ingredient and finished drug product are produced and tested to assess compliance with Current Good Manufacturing Practices, or cGMP, regulations;

 

FDA review and approval of the NDA prior to any commercial marketing or sale of the drug in the United States; and

 

Prior to commercialization, centrally acting drugs may be subject to review and potential scheduling by the DEA.

The development and approval process requires substantial expertise, time, effort and financial resources, and we cannot be certain that any approvals for our drug candidates will be granted on a timely basis, if at all.

The results of preclinical tests (which include laboratory evaluation as well as GLP studies to evaluate toxicity in animals) for a particular drug candidate, together with related manufacturing information and analytical data, are submitted as part of an IND to the FDA. The initial IND becomes effective 30 days after receipt by the FDA, following its initial safety review. During the 30-day time period the FDA may require additional information. The FDA may institute a clinical hold at the 30-day time period if any questions are not fully addressed or because of other concerns about the conduct of the clinical trial, including concerns that human research subjects will be exposed to unreasonable health risks. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. The FDA may place an IND on partial or full clinical hold at any time during a product candidate’s development. A separate submission to an existing IND must also be made for each successive clinical trial conducted during product development. Further, an independent institutional review board, or IRB, for each medical center proposing to conduct the clinical trial must review and approve the plan for any clinical trial before it commences at that center and it must monitor the study until completed. The FDA, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk. Clinical testing also must satisfy extensive Good Clinical Practice, or GCP, regulations and regulations for informed consent and privacy of individually identifiable information.

Clinical trials. For purposes of NDA submission and approval, clinical trials are typically conducted in the following sequential phases, which may overlap:

 

Phase 1 clinical trials. Studies are initially conducted in a limited population to test the drug candidate for safety, dose tolerance, absorption, metabolism, distribution and excretion, typically in healthy volunteers, but in some cases in patients.

 

Phase 2 clinical trials. Studies are generally conducted in a limited patient population to identify possible adverse effects and safety risks, explore the initial efficacy of the product for specific targeted indications and to determine dose range or pharmacodynamics. Multiple Phase 2 clinical trials may be conducted by the sponsor to obtain information prior to beginning larger and more expensive Phase 3 clinical trials.

15


 

 

Phase 3 clinical trials. These are commonly referred to as pivotal studies or adequate and well-controlled studies. When Phase 2 evaluations demonstrate that a dose range of the product is effective and has an acceptable safety profile, Phase 3 clinical trials are undertaken in large patient populations to further evaluate dosage, provide substantial evidence of clinical efficacy and further test for safety in an expanded and diverse patient population at multiple, geographically dispersed clinical trial centers.

 

Phase 4 clinical trials. The FDA may approve an NDA for a drug candidate but require that the sponsor conduct additional clinical trials to further assess the drug after NDA approval under a post-approval commitment. In addition, a sponsor may decide to conduct additional clinical trials after the FDA has approved an NDA. Post-approval trials are typically referred to as Phase 4 clinical trials.

New drug applications. The results of drug development, preclinical studies and clinical trials are submitted to the FDA as part of an NDA. NDAs also must contain extensive chemistry, manufacturing and control, or CMC, information. An NDA is usually accompanied by a significant user fee. The FDA reviews all NDAs submitted to ensure that they are sufficiently complete for substantive review before it accepts them for filing, which occurs, if at all, 60 days after submission by the NDA sponsor. Once the submission has been accepted for filing, the FDA’s goal is to review applications within 10 months from its acceptance of the filing or, if the application relates to an unmet medical need in a serious or life-threatening indication, six months from its acceptance of the filing. The review process can be significantly extended by FDA requests for additional information or clarification. The FDA may refer the application to an advisory committee for review, evaluation and recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory committee. The FDA may deny approval of an NDA by issuing a Complete Response Letter, or CRL, if the applicable regulatory criteria are not satisfied. A CRL may require additional clinical data and/or an additional pivotal Phase 3 clinical trial(s), and/or other significant, expensive and time-consuming requirements related to clinical trials, preclinical studies or manufacturing. Data are not always conclusive, and the FDA may interpret data differently than we or our collaborators interpret data. Approval may occur with Risk Evaluation and Mitigation Strategies, or REMS, that may limit the labeling, distribution or promotion of a drug product. Once issued, the FDA may withdraw product approval if ongoing regulatory requirements are not met or if safety problems occur after the product reaches the market. In addition, the FDA may require testing, including Phase 4 clinical trials, and surveillance programs to monitor the safety effects of approved products which have been commercialized, and the FDA has the power to prevent or limit further marketing of a product based on the results of these postmarketing programs or other information.

Expedited Development and Review Programs. The FDA has four programs that are intended to facilitate and expedite development and review of new drugs to address unmet medical need in the treatment of a serious or life-threatening condition: fast track designation, breakthrough therapy designation, accelerated approval, and priority review designation. These programs do not change the standards for approval but may expedite the development or approval process.

New investigational drugs may qualify for fast track designation if they are intended to treat a serious condition and nonclinical or clinical data demonstrate the potential to address unmet medical need. Fast track designation applies to the drug (either alone or in combination with other drugs) and the specific indication for which it is being studied. A fast track product is afforded opportunities for frequent interactions with the FDA to support efficient development and may be eligible for priority review if supported by clinical data at the time of NDA submission. After preliminary evaluation of clinical data and a determination that a fast track product may be effective, the FDA may consider reviewing portions of an NDA before the complete application is submitted (“rolling review”), if the sponsor gains FDA agreement on the proposed schedule for submission of the various sections of the NDA and the sponsor pays any required user fees upon submission of the first section of the NDA.

An NDA for a drug that treats a serious condition and, if approved, would provide a significant improvement in safety or effectiveness compared to marketed products may qualify for priority review designation. A priority review designation means that the FDA’s goal is to take action on the NDA within six months of the filing date as compared to ten months under its standard review.

In addition, a product may qualify for an accelerated approval pathway if it meets three criteria: treats a serious condition; generally provides a meaningful advantage over available therapies; demonstrates 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 other clinical benefit. As a condition of approval, the FDA may require that a sponsor of a drug receiving accelerated approval perform adequate and well controlled post marketing clinical trials to verify the predicted clinical benefit. Products receiving accelerated approval may be subject to expedited withdrawal procedures if the sponsor fails to conduct the required post-market studies or if such studies fail to verify the predicted 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.

The Food and Drug Administration Safety and Innovation Act established a category of drugs and biologics referred to as “breakthrough therapies”, and a drug candidate may qualify for breakthrough therapy designation if it is intended to treat a serious

16


 

condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement on a clinically significant endpoint(s) over available therapies. Breakthrough therapy designation affords all of the fast track designation features, as well as more intensive FDA interaction and guidance. Breakthrough therapy designation is distinct from both the accelerated approval pathway and priority review designation, which can also be granted to the same drug if relevant criteria are met.

Other US regulatory requirements. Products manufactured or distributed pursuant to FDA approvals are subject to continuing regulation by the FDA, including recordkeeping, annual product quality review and reporting requirements. Adverse event experience with the product must be reported to the FDA in a timely fashion and pharmacovigilance programs to proactively look for these adverse events are mandated by the FDA. Drug manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies and are subject to periodic inspections (which may be unannounced) by the FDA and certain state agencies for compliance with ongoing regulatory requirements, including cGMP regulations, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Following such inspections, the FDA may issue notices on Form FDA 483 and warning letters that could cause us to modify certain activities. A Form FDA 483 notice, if issued at the conclusion of an FDA inspection or after the appropriate FDA office review of the Establishment Inspection Report prepared by the investigator, can list conditions the FDA believes may have violated cGMP or other FDA regulations. FDA guidelines specify that a warning letter be issued for violations of “regulatory significance,” also known as Official Action Indicated, or OAI. Failure to adequately and promptly correct the observation(s) can result in regulatory action. In addition to Form FDA 483 notices and warning letters, failure to comply with the statutory and regulatory requirements can subject a manufacturer to possible legal or regulatory action, such as suspension of manufacturing, recall of product, seizure of product, injunctive action or possible civil or criminal penalties.

The FDA closely regulates the post-approval marketing and promotion of drugs, including standards and regulations for healthcare professional marketing activities and materials, direct-to-consumer advertising, dissemination of off-label information, industry-sponsored scientific and educational activities and promotional activities involving the Internet. Drugs may be marketed only for their approved indications and in accordance with the provisions of the confines of the pivotal studies and the approved label. Further, we may be required to develop additional data or conduct additional preclinical studies and clinical trials, and we may be required to submit and obtain FDA approval of a new or supplemental NDA for changes to, among other things, the indications, labeling, or manufacturing processes or facilities of a drug. Failure to comply with these requirements can subject a manufacturer to possible legal or regulatory action, such as warning letters, corrective advertising, suspension of manufacturing, seizure of product, injunctive action or potential civil and criminal penalties.

Physicians may prescribe legally available drugs for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA, if in their professional medical judgment, the physicians deem such use to be appropriate. Such off-label uses are common across certain medical specialties. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, impose stringent restrictions on manufacturers’ communications regarding off-label use.

To distribute products commercially, we or our collaborators, as applicable, must comply with state laws that require the registration of manufacturers and wholesale distributors of pharmaceutical products in a state, including, in certain states, manufacturers and distributors who ship products into the state even if such manufacturers or distributors have no place of business within the state. Some states also impose requirements on manufacturers and distributors to establish the pedigree of product in the chain of distribution.

Drug Enforcement Administration regulation. The DEA regulates drugs that are controlled substances. Controlled substances are those drugs that appear on one of the five schedules promulgated and administered by the DEA under the Controlled Substances Act, or CSA. The CSA governs, among other things, the inventory, distribution, recordkeeping, handling, security and disposal of controlled substances. Any drug that acts on the central nervous system has the potential to become a controlled substance based on an evaluation of its abuse potential, and scheduling by the DEA is a separate process that may delay the commercial launch of a drug even after FDA approval of the NDA. Companies with a scheduled drug are subject to periodic and ongoing inspections by the DEA and similar state drug enforcement authorities to assess ongoing compliance with the DEA’s regulations. Any failure to comply with these regulations could lead to a variety of sanctions, including the revocation or a denial of renewal of any DEA registration, injunctions, or civil or criminal penalties.

Hatch-Waxman Exclusivity. Market exclusivity provisions of the Hatch-Waxman Act can delay the submission or approval of applications seeking to rely upon the FDA’s findings of safety and effectiveness for a previously approved NDA. A new chemical entity, or NCE, subject to an NDA is entitled to a five-year period of non-patent marketing exclusivity in the United States. A drug is an NCE if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an abbreviated new drug application, or ANDA, or a 505(b)(2) NDA submitted by another company for another version of such drug where the applicant does not own or have a legal right of reference to all the data required for approval. However, such an application may be submitted

17


 

after four years if it contains a certification of patent invalidity or non-infringement of patents listed with the FDA by the NDA holder. The Hatch-Waxman Act also provides three years of marketing exclusivity for an NDA, or supplement to an existing NDA, if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application. This three-year exclusivity covers only the conditions of use associated with the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs containing the original active ingredient. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

Orphan drug designation and exclusivity. Under the Orphan Drug Act, the FDA may designate a drug product as an “orphan drug” if it is intended to treat a rare disease or condition (generally meaning that it affects fewer than 200,000 individuals in the United States, or more in cases in which there is no reasonable expectation that the cost of developing and making a drug product available in the United States for treatment of the disease or condition will be recovered from sales of the product). A company must request orphan product designation before submitting an NDA. If the request is granted, the FDA will disclose the identity of the therapeutic agent and its potential use. Orphan product designation does not convey any advantage in or shorten the duration of the regulatory review and approval process.

If a product with orphan status receives the first FDA approval for the disease or condition for which it has such designation or for a select indication or use within the rare disease or condition for which it was designated, the product generally will receive orphan product exclusivity. Orphan product exclusivity means that the FDA may not approve any other applications for the same product for the same indication for seven years, except in certain limited circumstances. Competitors may receive approval of different products for the indication for which the orphan product has exclusivity and may obtain approval for the same product but for a different indication or the same product for the same indication if demonstrated to be clinically superior. If a drug or drug product designated as an orphan product ultimately receives marketing approval for an indication broader than what was designated in its orphan product application, it may not be entitled to exclusivity.

Pediatric exclusivity. The FDA may issue Written Requests for pediatric studies prior to approval of a new drug application, if the FDA has determined that information related to the use of the drug in the pediatric population may produce health benefits. As an incentive to industry to conduct such studies requested by the FDA, a 6-month period of additional exclusivity may be granted as an add-on to existing marketing exclusivity periods and patent terms.

Outside of the United States

In addition to regulations in the United States, we will be subject to a variety of regulations in other jurisdictions governing, among other things, clinical studies and any commercial sales and distribution of products. Whether or not we obtain FDA approval for a product candidate, we must obtain the requisite approvals from regulatory authorities in foreign jurisdictions prior to the commencement of clinical studies or marketing and sale of the product in those jurisdictions.

Certain countries outside of the United States have a similar process that requires the submission of a clinical trial application much like the IND prior to the commencement of human clinical trials. In the EU, for example, a Clinical Trial Application, or CTA, must be submitted to the national health authority and an independent ethics committee in each country in which we intend to conduct clinical trials, much like the FDA and IRB, respectively. Once the CTA is approved in accordance with a country’s requirements, clinical trial development may proceed in that country. Under the new Regulation on Clinical Trials, which is expected to take effect in 2021, there will be a centralized application procedure in respect of clinical trials to be conducted in the EU where one national authority will take the lead in reviewing the application and the other national authorities have more limited involvement. Any substantial changes to the trial protocol or other information submitted with the clinical trial applications must be notified to or approved by the relevant competent authorities and ethics committees.

The requirements and process governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, the clinical trials are conducted in accordance with GCP and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

To obtain regulatory approval of an investigational drug or biological product in the EU, we must submit a marketing authorization application either under the so-called centralized or national authorization procedures.

Centralized procedure. The centralized procedure provides for the grant of a single marketing authorization, which is issued by the European Commission based on the opinion of the Committee for Medicinal Products for Human Use, or the CHMP, of the European Medicines Agency, or EMA, and that is valid in all EU member states, as well as Iceland, Liechtenstein and Norway (together, the “EEA”). The Centralized Procedure is mandatory for certain types of products, such as biotechnology medicinal

18


 

products, orphan medicinal products, and medicines that contain a new active substance indicated for the treatment of AIDS, cancer, neurodegenerative disorders, diabetes, auto-immune and viral diseases. The Centralized Procedure is optional for products containing a new active substance not yet authorized in the EEA, or for products that constitute a significant therapeutic, scientific or technical innovation or which are in the interest of public health in the EU. Under the Centralized Procedure the maximum timeframe for the evaluation of an MAA is 210 days (excluding clock stops, when additional written or oral information is to be provided by the applicant in response to questions asked by the CHMP). Accelerated evaluation might be granted by the CHMP in exceptional cases when the authorization of a medicinal product is of major interest from the point of view of public health and in particular from the viewpoint of therapeutic innovation. Under the accelerated procedure the standard 210-day review period is reduced to 150 days.

National authorization procedures. There are also two other possible routes to authorize medicinal products in several EU Member States, which are available for investigational medicinal products that fall outside the scope of the centralized procedure:

 

Decentralized procedure. Using the decentralized procedure, an applicant may apply for simultaneous authorizations in more than one EU country of medicinal products that have not yet been authorized in any EU Member State and that do not fall within the mandatory scope of the centralized procedure.

 

Mutual recognition procedure. In the mutual recognition procedure, a medicine is first authorized in one EU Member State, in accordance with the national procedures of that country. Following this, further marketing authorizations can be sought from other EU Member States in a procedure whereby the countries concerned agree to recognize the validity of the original, national marketing authorization.

In the EEA, upon receiving marketing authorization, new chemical entities generally receive eight years of data exclusivity and an additional two years of market exclusivity. If granted, data exclusivity prevents regulatory authorities in the EU from referencing the innovator’s data to assess a generic application. During the additional two-year period of market exclusivity, a generic marketing authorization can be submitted, and the innovator’s data may be referenced, but no generic product can be marketed until the expiration of the market exclusivity. However, there is no guarantee that a product will be considered by the EU’s regulatory authorities to be a new chemical entity and qualify for data exclusivity.

The EMA grants orphan drug designation to promote the development of products that may offer therapeutic benefits for life-threatening or chronically debilitating conditions affecting not more than five in 10,000 people in the EU. In addition, orphan drug designation can be granted if the drug is intended for a life threatening, seriously debilitating or serious and chronic condition in the EU and without incentives it is unlikely that sales of the drug in the EU would be sufficient to justify developing the drug. Orphan drug designation is only available if there is no other satisfactory method approved in the EU of diagnosing, preventing or treating the condition, or if such a method exists, the proposed orphan drug will be of significant benefit to patients. Orphan drug designation provides opportunities for free protocol assistance, fee reductions for access to the centralized regulatory procedures and ten years of market exclusivity following drug approval, which can be extended to 12 years if trials are conducted in accordance with an agreed-upon pediatric investigational plan. The exclusivity period may be reduced to six years if the designation criteria are no longer met, including where it is shown that the product is sufficiently profitable not to justify maintenance of market exclusivity.

Great Britain, or GB, is no longer covered by the EEA’s procedures outlined above (Northern Ireland will be covered by the centralized authorization procedure and can be covered under the decentralized or mutual recognition procedures). A separate marketing authorization will be required to market drugs in GB.  However, for two years from 1 January 2021, the MHRA may adopt decisions taken by the European Commission on the approval of new marketing authorizations through the centralized procedure, and the MHRA will have regard to marketing authorizations approved in a country in the EEA (although in both cases a marketing authorization will only be granted if any GB-specific requirements are met). Various national procedures are now available to place a drug on the market in the UK, GB, or Northern Ireland, with the main national procedure having a maximum timeframe of 150 days (excluding time taken to provide any further information or data required).  The data exclusivity periods in the UK are currently in line with those in the EU, but the Trade and Cooperation Agreement agreed between the UK and EU provides that the periods for both data and market exclusivity are to be determined by domestic law, and so there could be divergence in the future.  

Orphan designation in GB following Brexit is largely aligned with the position in the EU but is based on the prevalence of the condition in GB.  It is therefore possible that conditions that are currently designated as orphan conditions in GB will no longer be and that conditions that are not currently designated as orphan conditions in the EU will be designated as such in GB.

Prescription drug reimbursement. In the United States and markets in other countries, sales of prescription drug products depend in part on the availability of reimbursement from third-party payers. Third-party payers include government health administrative authorities, managed care organizations, private health insurers and other organizations. The process for determining whether a payer will provide coverage for a drug product may be separate from the process for setting the price or reimbursement rate that the payer will pay for the drug product. Third-party payers may limit coverage to specific drug products on an approved list, or formulary, which might not include all of the FDA-approved drug products for a particular indication. Third-party payers are increasingly challenging the price and examining the medical necessity and cost-effectiveness of medical products and services, in

19


 

addition to their safety and efficacy. We may need to conduct expensive pharmacoeconomic studies to demonstrate the cost-effectiveness of our products. A payer’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development. Patients who are prescribed medications for the treatment of their conditions, and their prescribing physicians, generally rely on third-party payers to reimburse all or part of the costs associated with their prescription drugs. Patients are less likely to use our products unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our products. Therefore, coverage and adequate reimbursement are important to new product acceptance.

If a drug is reimbursed by Medicare or Medicaid, pricing and rebate programs must comply with, as applicable, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 as well as the Medicaid rebate requirements of the Omnibus Budget Reconciliation Act of 1990 and the Veterans Health Care Act of 1992, or VHCA, each as amended. If products are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. Under the VHCA, drug companies are required to offer certain drugs at a reduced price to a number of federal agencies including US Department of Veterans Affairs and US Department of Defense, the Public Health Service and certain private Public Health Service designated entities in order to participate in other federal funding programs including Medicare and Medicaid. Participation under the VHCA requires submission of pricing data and calculation of discounts and rebates pursuant to complex statutory formulas, as well as entry into government procurement contracts governed by the Federal Acquisition Regulations.

The containment of healthcare costs has become a priority of federal, state and foreign governments, and the prices of drugs have been a focus in this effort, which has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. In addition, emphasis on managed care in the United States has increased and we expect will continue to increase the pressure on drug pricing. Coverage policies, third-party reimbursement rates and drug pricing regulation may change at any time. In particular, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the ACA, was enacted in the United States in March 2010 and contains provisions that may reduce the profitability of drug products, including, for example, increased rebates for drugs sold to Medicaid programs, extension of Medicaid rebates to Medicaid managed care plans, mandatory discounts for certain Medicare Part D beneficiaries and annual fees based on pharmaceutical companies’ share of sales to federal healthcare programs. There have been judicial and Congressional challenges to certain aspects of the ACA. For example, since January 2017, President Trump has signed Executive Orders and other directives designed to delay the implementation of certain provisions of the ACA or otherwise circumvent some of the requirements for health insurance mandated by the ACA. Concurrently, Congress has considered legislation that would repeal or repeal and replace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, bills affecting the implementation of certain taxes under the ACA have been signed into law. Legislation enacted in 2017, informally titled the Tax Cuts and Jobs Act of 2017, or TCJA, includes a provision that repealed, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA 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”. Additionally, the 2020 federal spending package permanently eliminated, effective January 1, 2020, the PPACA-mandated “Cadillac” tax on high-cost employer-sponsored health coverage and medical device tax and, effective January 1, 2021, also eliminated the health insurer tax. Further, the Bipartisan Budget Act of 2018, or the BBA, among other things, amended the ACA, effective January 1, 2019, to increase from 50 percent to 70 percent the point-of-sale discount that is owed by pharmaceutical manufacturers who participate in Medicare Part D and to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”. On December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of the TCJA. On December 18, 2019, the U.S. Court of Appeals for the 5th Circuit upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District Court to determine whether the remaining provisions of the PPACA are invalid as well. The United States Supreme Court is currently reviewing this case, but it is unknown when a decision will be made. Although the U.S. Supreme Court has not yet ruled on the constitutionality of the ACA, on January 28, 2021, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through May 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructs 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 ACA. It is unclear how the Supreme Court ruling, other such litigation, and the healthcare reform measures of the Biden administration will impact the ACA and our business and operations.

Further, the Trump administration’s budget proposal for fiscal year 2021 included a $135 billion allowance to support legislative proposals seeking to reduce drug prices, increase competition, lower out-of-pocket drug costs for patients, and increase patient access to lower-cost generic and biosimilar drugs.  On July 24, 2020 and September 13, 2020, President Trump announced several executive orders related to prescription drug pricing that seek to implement several of the administration’s proposals. The FDA also released a final rule on September 24, 2020 providing guidance for states to build and submit importation plans for drugs

20


 

from Canada. Further, on November 20, 2020, HHS finalized a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, as well as a safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers. On November 20, 2020, CMS issued an interim final rule implementing President Trump’s Most Favored Nation executive order, which would tie Medicare Part B payments for certain physician-administered drugs to the lowest price paid in other economically advanced countries, effective January 1, 2021. On December 28, 2020, the United States District Court in Northern California issued a nationwide preliminary injunction against implementation of the interim final rule. However, it is unclear whether the Biden administration will work to reverse these measures or pursue similar policy initiatives. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

In countries outside the United States, pricing of pharmaceutical products may be subject to governmental control. Evaluation criteria used by many government agencies for the purposes of pricing and reimbursement typically focus on a product’s degree of innovation and its ability to meet a clinical need unfulfilled by currently available therapies. Some countries operate positive and negative list systems under which products may only be marketed once a reimbursement price has been agreed. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost-effectiveness of a particular drug candidate to currently available therapies. Other countries allow companies to fix their own prices for medicines but monitor and control company profits. In addition, in some countries, cross-border imports from low-priced markets exert a commercial pressure on pricing within a country. There can be no assurance that any country that has price controls or reimbursement limitations for drug products will allow favorable reimbursement and pricing arrangements for any of our products.

Healthcare fraud and abuse. Pharmaceutical companies are subject to various federal and state laws pertaining to healthcare fraud and abuse, including, but not limited to, anti-kickback and false claims laws.

The Federal Anti-Kickback Statute makes it illegal for any person or entity, including a prescription drug manufacturer, or a party acting on its behalf, to knowingly and willfully solicit, offer, receive or provide any remuneration, directly or indirectly, in exchange for, or to induce, the referral of business, including the purchase, order, lease of any good, facility, service or item, including the prescription of a particular drug, for which payment may be made under federal healthcare programs such as Medicare and Medicaid. Some of the state prohibitions are broader in scope and apply to referral of patients for healthcare services reimbursed by any source, not only the Medicare and Medicaid programs.

In the course of practicing medicine, physicians may legally prescribe FDA-approved drugs for an indication that has not been approved by the FDA and which, therefore, is not described in the product’s approved labeling, so-called “off-label use” or “the practice of medicine,” if deemed appropriate in the physicians’ professional medical judgment. The FDA does not ordinarily regulate the behavior of physicians in their choice of treatments. The FDA and other government agencies do, however, restrict communications on the subject of off-label use by a manufacturer or those acting on behalf of a manufacturer. Companies may not promote FDA-approved drugs for off-label uses. The FDA and other governmental agencies do permit a manufacturer (and those acting on its behalf) to engage in some limited, non-misleading, non-promotional exchanges of scientific information regarding unapproved indications.

There are numerous federal false claims laws and civil monetary penalty laws that forbid, among other things, anyone from knowingly presenting, or causing to be presented for payment to third-party payers (including Medicare and Medicaid) claims for reimbursed drugs or services that are false or fraudulent, claims for items or services not provided as claimed or claims for medically unnecessary items or services.

In addition, the federal transparency requirements under the Physician Payments Sunshine Act require applicable manufacturers of covered drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program, with specific exceptions, to track and annually report to the Centers for Medicare & Medicaid Services, or CMS, payments and other transfers of value provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, and certain ownership and investment interests held by physicians or their immediate family members. Beginning in 2022, applicable manufacturers also will be required to report such information regarding their transfers of value during the previous year to physician assistants, nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, anesthesiologist assistants, and certified nurse midwives.

We may also be subject to state equivalents of these fraud and abuse laws.

21


 

Violations of fraud and abuse laws may be punishable by criminal, civil and/or administrative sanctions, including individual imprisonment, disgorgement, criminal fines and civil monetary penalties, possible exclusion from federal healthcare programs (including Medicare and Medicaid), and integrity oversight and reporting obligations to resolve allegations of non-compliance with these laws. In addition, under certain healthcare fraud and abuse laws, there is an ability for private individuals to bring similar actions. Additionally, many states have analogous fraud and abuse laws, some of which may be broader in scope. Further, there are an increasing number of state laws that require pharmaceutical companies to establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, clinical trials and other activities, or register their sales representatives, as well as prohibiting certain other sales and marketing practices. The federal transparency requirements under the ACA require certain manufacturers of drugs, devices, biologics and medical supplies to annually report to the Department of Health and Human Services information related to payments and other transfers of value to physicians and teaching hospitals and physician ownership and investment interests. Additionally, recent federal legislation imposes additional obligations on certain pharmaceutical manufacturers, among others, regarding drug product tracking and tracing.

Our activities are also potentially subject to federal and state consumer protection and unfair competition laws. We are also subject to the US Foreign Corrupt Practices Act, or the FCPA, which prohibits companies and individuals from engaging in specified activities to obtain or retain business or to influence a person working in an official capacity. Under the FCPA, it is illegal to pay, offer to pay, or authorize the payment of anything of value to any foreign government official, governmental staff members, political party or political candidate in an attempt to obtain or retain business or to otherwise influence a person working in an official capacity.

Healthcare and other privacy and security laws. We are subject to numerous laws and regulations regarding the privacy, protection, and security of health information and other personal information. These laws and regulations impose obligations and restrictions on us with respect to the collection, storage, use, disclosure, transfer and security of personal information.

The Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act and its implementing regulations, imposes obligations with respect to safeguarding the privacy, security and transmission of individually identifiable health information on covered entities and their business associations and covered subcontractors that perform services for them involving individually identifiable health information. We may be subject to, or our collaborators’ marketing activities may be limited by, HIPAA and its implementing regulations. In addition, many state laws apply to the use and disclosure of health and other personal information.

For example, as of January 1, 2020, we are subject to the California Consumer Privacy Act, or CCPA. The CCPA has created new individual privacy rights for California residents and places increased privacy and security obligations on entities handling the personal information of such residents. Among other obligations, the CCPA requires covered businesses to provide new disclosures to California residents and to respond to requests to access and/or delete personal information. The CCPA also allows for a private right of action for data breaches.

The European General Data Protection Regulation, or GDPR, imposes many requirements and restrictions that impact our collection, transfer, use and retention of personal data of clinical trial subjects and other individuals in the European Union. For example, the GDPR dictates mandatory contractual terms for service providers that process personal data for us and restricts our ability to transfer data from the European Economic Area to our offices and service providers in the United States and other countries.  Penalties for non-compliance with the GDPR are steep, with potential fines of up to 4% of our global revenue.

Because we have operations in Switzerland, we also are required to comply with the data privacy and security laws and regulations of that country. As we conduct clinical trials and other activities that involve the collection of personal data from individuals in other countries and regions, we may be subject to additional data privacy and security laws and regulations.

Across the United States and globally, laws and regulations governing data privacy and security continue to develop and evolve. The data privacy and security laws and regulations to which we are subject will likely impact (possibly significantly) our business activities. Many of the laws and regulations that apply to us contain ambiguous provisions or impose requirements that differ from country to country, creating uncertainty. Compliance with the enhanced obligations imposed by such laws and regulations may require us to revise our business practices, allocate more resources to privacy and security, and implement new technologies. Such efforts may result in significant costs to our business.

Failure to comply with data privacy and security laws and regulations could result in regulatory penalties and significant legal liability and could have a material adverse impact on our financial results.

Manufacturing, Revenues from External Customers, and Sources and Availability of Materials

Our revenues of $0.3 million for the year ended December 31, 2020 primarily included royalty revenue from Eisai. Our revenues of $806.4 million for the year ended December 31, 2019, included an $800.0 million upfront payment from United Therapeutics, $5.0 million from Everest, and $1.7 million from Boehringer Ingelheim. Our revenues of $18.0 million for the year ended December 31, 2018, included $6.6 million from Eisai, $4.4 million from Boehringer Ingelheim, $2.8 million from Outpost Medicine, $2.2 million from Axovant, and $2.0 million from Everest. This information excludes revenue activity reported within discontinued operations. See “Note 5. Sale of Manufacturing Operations” to our consolidated financial statements included in this Annual Report for additional information. We do not currently engage in manufacturing activities and we are not dependent on availability of materials for our core business operations.

Compliance with Environmental Regulations

Our business involves the controlled use of hazardous materials, chemicals, biological materials and various radioactive compounds. In the United States, we are subject to regulation under the Occupational Safety and Health Act, the Environmental Protection Act, the US Environmental Protection Agency, the California Environmental Protection Agency, the Toxic Substances Control Act, the Resource Conservation and Recovery Act, the CSA and other federal, state or local regulations.

We may be subject to further such regulations in the future. Although we believe that our operations comply in all material respects with the applicable environmental laws and regulations, the risk of accidental contamination or injury from these materials cannot be eliminated. In the event of such an accident, we could be held liable for any damages that result, and the extent of that liability could exceed our resources. Our compliance with these laws and regulations has not had, and is not expected to have, a material effect upon our capital expenditures, results of operations or competitive position.

Item 1A.    Risk Factors.

RISK FACTORS

Investment in our stock involves a high degree of risk. You should consider carefully the risks described below, together with other information in this Annual Report on Form 10-K and our other filings with the SEC, before making investment decisions regarding our stock. If any of the following events actually occur, our business, operating results, prospects or financial condition could be materially and adversely affected. This could cause the trading price of our common stock to decline and you may lose all or part of your investment. Moreover, the risks described below are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also affect our business, operating results, prospects or financial condition.

Risks Relating to Our Business

Drug development programs are expensive, time consuming, uncertain and susceptible to change, interruption, delay or termination.

Drug development programs are very expensive, time consuming and difficult to design and implement. Our drug candidates are in various stages of clinical and preclinical development and are prone to the risks of failure inherent in research and development. Clinical trials and preclinical studies are needed to demonstrate that drug candidates are safe and effective to the satisfaction of the FDA, and similar non-US regulatory authorities, and the FDA or other regulatory authority may require us to, or we or others may decide to, conduct additional research and development even after a drug is approved. The commencement or completion of our clinical trials or preclinical studies could be substantially delayed or prevented by several factors, including the following:

 

limited number of, and competition for, suitable participants required for enrollment in our clinical trials or animals to conduct our preclinical studies;

 

limited number of, and competition for, suitable sites to conduct our clinical trials or preclinical studies;

 

delay or failure to obtain a meeting, approval or agreement from the applicable regulatory authority to commence a clinical trial or approve a study protocol;

 

delay or failure to obtain sufficient supplies of drug candidates, drugs or other materials for the trial or study;

 

delay or failure to reach agreement on acceptable agreement terms or protocols;

 

delay or other disruption related to the COVID-19 pandemic; and

 

delay or failure to obtain institutional review board, or IRB, approval to conduct a clinical trial at a prospective site.

 

For example, recruitment for the indications in our ongoing and planned clinical studies is competitive and challenging, and it is difficult to predict when such trials will be fully enrolled or when data will be available, if at all.

In addition, the FDA, other regulatory authorities, collaborators, or we may suspend, delay or terminate our development programs at any time for various reasons, including those listed above affecting the commencement or completion of trials and the following:

 

side effects experienced by study participants or other safety issues;

 

lack of effectiveness of any drug candidate during clinical trials;

 

slower than expected rates of patient recruitment and enrollment or lower than expected patient retention rates;

 

difficulty in maintaining contact with participants during or after treatment, which may result in incomplete data;

 

inability or unwillingness of medical investigators to follow our clinical protocols;

 

inadequacy of or changes in the manufacturing process or compound formulation;

 

delays in obtaining regulatory approvals to commence a study, or “clinical holds,” or delays requiring suspension or termination of a study by a regulatory authority, such as the FDA, after a study is commenced;

 

changes in applicable regulatory policies and regulations;

 

delays in identifying and reaching agreement on acceptable terms with prospective clinical trial sites;

 

uncertainty regarding proper dosing;

 

unfavorable results from clinical trials or preclinical studies, including those conducted by us, our partners or our licensees;

24


 

 

failure of our clinical research organizations to comply with all regulatory and contractual requirements or otherwise perform their services in a timely or acceptable manner;

 

scheduling conflicts with participating clinicians and clinical institutions;

 

failure to design appropriate clinical trial protocols;

 

insufficient data to support regulatory approval;

 

failure of participating clinicians and clinical institutions to comply with all legal, regulatory and contractual requirements or otherwise perform in a timely or acceptable manner;

 

lack of sufficient funding to continue clinical trials or preclinical studies; or

 

changes in business priorities or perceptions of the value of the program.

There is typically a high rate of attrition from the failure of drug candidates proceeding through clinical trials, and many companies have experienced significant setbacks in advanced development programs, even after promising results were observed in earlier studies or trials. We have experienced setbacks in our internal and partnered development programs and expect to experience additional setbacks from time to time in the future. In addition, even if the earlier-stage results of our development programs are favorable, these programs may take significantly longer than expected to complete or may not be completed at all. If we or our collaborators abandon or are delayed in our development efforts related to any drug or drug candidate, we may not be able to generate sufficient revenues to continue our operations at the current or planned level or be profitable, our reputation in the industry and in the investment community would likely be significantly damaged, additional funding may not be available to us or may not be available on terms we or others believe are favorable, and our stock price may decrease significantly.

We may not be successful in initiating, enrolling participants in, or completing our studies or trials or advancing our programs on our projected timetable, if at all. Any failure to initiate or delays in our studies, trials or development programs, or unfavorable results or decisions or negative perceptions regarding any of our programs, could cause our stock price to decline significantly. This is particularly the case with respect to our clinical programs.

We will need to obtain additional funds or enter into collaboration agreements to execute on our corporate strategy, and we may not be able to do so at all or on terms you view as favorable; your ownership may be substantially diluted if we do obtain additional funds; you may not agree with the manner in which we allocate our available resources; and we may not be profitable.

It takes many years and potentially hundreds of millions of dollars to successfully develop a compound into a marketed drug. We have accumulated a large deficit that has primarily resulted from the significant expenditures we have made in research and development since our inception. We expect that our losses and operating expenses will continue to be substantial.

All of our internal programs are in the development stage, and we may not have adequate funds to develop all of our compounds into marketed drugs.

We may seek to obtain additional funding through the capital markets or other financing sources. Additional funding may not be available to us or may not be available on terms we or others believe are favorable, including due to negative impacts on the stock market and investor sentiment resulting from the COVID-19 pandemic. Our ability to obtain additional funding may depend on many factors, including those outside our control. Should we obtain additional funding, your ownership interest may be diluted or otherwise negatively impacted.

We have entered into, and may in the future seek to enter into, collaboration or other agreements with other entities to continue to develop and, if successful, commercialize one or more of our drug candidates. We may not be able to enter into any such agreements on terms that we or third parties, including investors or analysts, view as favorable, if at all. Our ability to enter into any such agreement for any of our programs or drug candidates depends on many factors, potentially including the outcomes of additional testing (including clinical trial results) or regulatory applications for marketing approval, and we do not control these outcomes.

We may allocate our resources in ways that do not improve our results of operations or enhance the value of our assets, and our stockholders and others may also not agree with the manner in which we choose to allocate our resources or obtain additional funding. We may also eliminate, scale back, or delay some or all of our research and development programs, and any such reductions or failure to apply our resources effectively or to obtain additional funding could narrow, slow, or otherwise adversely impact the development and commercialization of one or more of our drug candidates, which could reduce our opportunities for success and have a material adverse effect on our business, our prospects, and the market price of our common stock.

25


 

In addition, we cannot assure you that we will be profitable or, if we are profitable for any particular time period, that we will be profitable in the future.

Our business may be negatively impacted based on the clinical trials and preclinical studies of, and decisions affecting, one or more of our drug candidates.

The results and timing of clinical trials and preclinical studies obtained by us or our collaborators or licensees, as well as related decisions by us, collaborators, licensees, and regulators, can affect our stock price. Results of clinical trials and preclinical studies are uncertain and subject to different interpretations by regulatory agencies, us, or others. The design of these trials and studies (which may change significantly and be more expensive than anticipated depending on results and regulatory decisions), as well as related analyses of such results, including adverse effects, may not be viewed favorably by us or third parties, including investors, analysts, current or potential collaborators, the academic and medical communities, and regulators, which could adversely impact the development and opportunities for regulatory approval of drug candidates and commercialization (and even result in withdrawal from the market) of approved drugs. The same may be true of decisions regarding the focus and prioritization of our research and development efforts. Stock prices of companies in our industry have declined significantly when such results and decisions were unfavorable or perceived negatively or when a drug candidate or product did not otherwise meet expectations.

The development, approval or commercialization of any of our drug candidates could be negatively affected by circumstances related to other drug candidates or approved products.

Information on our drug candidates in clinical development is preliminary and incomplete, and for such drug candidates, particularly in the earlier stages of development, information on approved products in the same or related drug classes may indicate potential risks related to the development of our drug candidates. In particular, safety issues affecting other drugs or drug candidates may result in increased regulatory scrutiny of the safety of our drugs or drug candidates, may raise potential adverse publicity, and may affect product sales or result in litigation.

For example, etrasimod is an orally available modulator of the S1P receptors. Other orally available modulators of the S1P receptors, such as Gilenya, have been associated with risks such as adverse cardiovascular effects, including lowering of the heart rate and heart blocks, infection, macular edema, respiratory effects, fetal risk, a rare brain infection, and elevations in liver enzymes. These adverse reactions and risks may be associated with S1P receptor modulation and could be found to be associated with the use of etrasimod. Such adverse reactions and risks, either actual or perceived, could negatively impact the development, approval, or commercialization of etrasimod, or our ability to enter into a collaboration on acceptable terms.

Topline data may not accurately reflect the complete results of a particular study or trial.

We may publicly disclose topline or interim data from time to time, which are based on preliminary analyses of then-available efficacy and safety data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial.

We also make assumptions, estimations, calculations, and conclusions as part of our analyses of data, and others, including regulatory agencies, may not accept or agree with our assumptions, estimations, calculations, conclusions, or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular drug candidate or drug, and our company in general. In addition, the information we may publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and you, regulators, or others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities, or otherwise regarding a particular drug, drug candidate or our business.

Our hypothesis that selectively targeting receptors can lead to more efficacious or safer drugs may not be correct.

In general, we have designed and optimized the drug candidates that we or our collaborators and licensees are developing (including etrasimod, olorinab, APD418 and ralinepag) to selectively target certain receptors found on cells in humans. Our hypothesis is that selectivity may allow our drug candidates to address diseases more efficaciously or without some of the negative effects associated with less selective drugs. In certain cases, we believe early research and, if available, early clinical testing, provides preliminary support for our hypothesis. However, our hypothesis may not be correct, early research and early phase clinical testing may not be predictive of efficacy or safety in later trials, and our drug candidates may not be approved or, if approved, have the desired efficacy or safety profile.

It is generally our strategy to develop drug candidates that we believe will be first-in-class, best-in-class, or similar descriptions, or otherwise have broad clinical utility, optimized pharmacology, or optimized pharmacokinetics. Some or all of our drug candidates

26


 

may not achieve these goals. For example, failure to complete enrollment in clinical trials on schedule or at all could prevent a drug candidate from being first-in-class. Similarly, comparing data from different trials, or making predictions based on preclinical data, may not allow us to correctly determine whether our drug candidates are superior to competitive drugs or drug candidates in the same way that comparisons can be made from conducting trials in which our and a competitive drug is tested “head to head” in the same trial. The failure of our drugs or drug candidates to be first-in-class, best-in-class, or similar descriptions, or have broad clinical utility, optimized pharmacology, or optimized pharmacokinetics, or a lack of “head to head” data, could adversely affect development, regulatory approval, third-party payor support, or market adoption, which could have a material adverse impact on our business.

The results of preclinical studies and completed clinical trials are not necessarily predictive of future results, and our current drug candidates or any approved drugs may not be further developed or have favorable results in later studies or trials.

Preclinical studies and Phase 1 and Phase 2 clinical trials are not primarily designed to test the efficacy of a drug candidate, but rather to establish potential mechanisms of action, test safety, study pharmacokinetics and pharmacodynamics, and understand the drug candidate’s side effects at various doses, schedules, or routes of administration. Favorable results in early studies or trials may not be confirmed in later studies or trials, including preclinical studies that continue or that are initiated after earlier clinical trials and large-scale clinical trials, and our drug candidates or drugs in subsequent trials or studies may fail to show desired safety and efficacy despite having progressed through earlier-stage trials. For example, we have announced positive topline Phase 2 results for etrasimod in participants with ulcerative colitis, but these results may not be confirmed in any subsequent Phase 3 study. By way of another example, the impact of etrasimod on heart rate that was observed in completed clinical trials may not be observed in subsequent trials, and it could be viewed negatively by the FDA or other regulatory agencies.

Unfavorable results from clinical trials or preclinical studies could result in delays, modifications, or abandonment of ongoing or future clinical trials, or abandonment of a program. Clinical and preclinical results are frequently susceptible to varying interpretations that may delay, limit, or prevent regulatory approvals or commercialization. Negative or inconclusive results or adverse medical events during such trials or studies could cause a clinical trial to be delayed, repeated, or terminated; a program to be abandoned; or negatively impact a related marketed drug, which could have a material adverse effect on our business, financial condition, and results of operations.

Our product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any.

Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay, or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, EMA or other comparable foreign authorities. Results of our trials could reveal a high and unacceptable severity and prevalence of these or other side effects. In such an event, our trials could be suspended or terminated, and the FDA, EMA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of our product candidates for any or all targeted indications. The drug-related side effects could affect patient recruitment or the ability of enrolled participants to complete the trial or result in potential product liability claims. Any of these occurrences may harm our business, financial condition, and prospects significantly.

Additionally, if one or more of our product candidates receives marketing approval, and we or others later identify undesirable side effects caused by such products, a number of potentially significant negative consequences could result, including:

 

regulatory authorities may withdraw approvals of such product;

 

regulatory authorities may require additional warnings on the label;

 

we may be required to create a medication guide outlining the risks of such side effects for distribution to patients;

 

we could be sued and held liable for harm caused to patients; and

 

our reputation may suffer.

For example, in February 2020 the FDA issued a drug safety communication announcing that it requested Eisai voluntarily withdraw lorcaserin (previously marketed in the United States as BELVIQ and BELVIQ XR) from the U.S. market based on the FDA’s analysis of data from a study completed by Eisai and a change in the FDA’s risk-benefit assessment of BELVIQ. Eisai agreed to voluntarily withdraw lorcaserin products from the U.S. market, as requested by the FDA, and from foreign markets. Following these events, lawsuits relating to lorcaserin against us and others have been filed in the United States and abroad.

Any of these events could prevent us from achieving or maintaining market acceptance of the particular product candidate, if approved, and could significantly harm our business, results of operations, and prospects.

27


 

Drug discovery and development is intensely competitive in the therapeutic areas on which we focus. If the number of our competitors increase or they develop treatments that are approved faster, marketed better, less expensive, or demonstrated to be more effective or safer than our drugs or drug candidates, our commercial opportunities could be reduced or eliminated.

Many of the drugs we or our collaborators are attempting or may attempt to discover and develop may compete with existing therapies in the United States and other territories. In addition, many companies are pursuing the development of new drugs that target the same diseases and conditions that we target. For example, with regard to etrasimod, there are other drugs that have a similar mechanism of action that entered Phase 3 clinical development before etrasimod for the same indications that we are pursuing, such as ulcerative colitis.

Our competitors, particularly large pharmaceutical companies, may have substantially greater research, development, marketing, and sales capabilities and greater financial, scientific, and human resources than we do. Companies that complete clinical trials, obtain required regulatory agency approvals, and commence commercial sale of their drugs before we do for the same indication may achieve a significant competitive advantage, including certain patent and marketing exclusivity rights. In addition, our competitors’ drugs may have fewer side effects, more desirable characteristics (such as efficacy, route of administration, or frequency of dosing), or be viewed more favorably by patients, healthcare providers, healthcare payers, the medical community, the media, or others than our drug candidates or drugs, if any, for the same indication. Our competitors may also market generic or other drugs that compete with our drugs at a lower price than our drugs, which may negatively impact our drug sales, if any. Any results from our research and development efforts, or from our joint efforts with our existing or any future collaborators, may not compete successfully with existing or newly discovered products or therapies.

Our revenues in the future will be substantially dependent on the success of our or our collaborators’ and licensees’ marketing of drugs we have discovered or developed. To the extent such drugs are not commercially successful, our business, financial condition, and results of operations may be materially adversely affected, and the price of our common stock may decline.

We believe our revenues will be substantially dependent on the success of the drugs we or our collaborators and licensees successfully develop. We do not know whether or when such drug candidates will be approved by regulatory authorities for sale or commercialized. Even if approved and commercialization begins, we do not know if such commercialization will be successful or otherwise meet our, your, analysts’, or others’ expectations, and the market price of our common stock could decline significantly. For example, sales of lorcaserin to date have been less than we and others initially anticipated, and, in February 2020, Eisai (as well as its distributor in South Korea) determined to withdraw lorcaserin (previously marketed in the United States as BELVIQ and BELVIQ XR) from the market based on concerns raised by the FDA.

We cannot guarantee future product sales or achievement of milestones under our collaborations and license agreements. For example, our license agreement with United Therapeutics for ralinepag does not contain a covenant obligating United Therapeutics to use any particular efforts to develop or commercialize any product, and we may never receive any milestone or royalty payments under this license agreement. In addition, our collaboration and license agreements may be terminated in certain circumstances, which may result in us not receiving additional milestone or other payments under the terminated agreement.

The degree of market acceptance and commercial success of a drug will depend on a number of factors, including the following, as well as risks identified in other risk factors:

 

the number of patients treated with the drug and their results;

 

market acceptance and use of the drug, which may depend on the public’s awareness and view of the drug, economic changes, national and world events, potentially seasonal and other fluctuations in demand, the timing and impact of current or new competition, and the drug’s perceived advantages or disadvantages over alternative treatments (including relative convenience, ease of administration, and prevalence and severity of any adverse events, including any unexpected adverse events);

 

the actual and perceived safety and efficacy of the drug on both a short- and long-term basis among actual or potential patients, healthcare providers and others in the medical community, regulatory agencies, and insurers and other payers, including related decisions by any such entity or individual;

 

incidence and severity of any side effects, including as a result of off-label use or in combination with one or more drugs;

 

new data relating to the drug, including as a result of additional studies, trials, or analyses of the drug or related drugs or drug candidates, whether conducted by us or by others;

 

physicians’ awareness of the drug, and the willingness of physicians to prescribe and of patients to use the drug;

 

the claims, limitations, warnings, and other information in the drug’s current or future labeling;

28


 

 

 

any current or future scheduling designation for the drug by the U.S. Drug Enforcement Administration, or DEA, or any comparable foreign authorities;

 

our or our collaborators’ maintenance of an effective sales force, marketing team, strategy, program, medical affairs group, and related functions, as well as our or our collaborators’ sales, marketing, and other representatives accurately describing the drug consistent with its approved labeling;

 

the price and perceived cost-effectiveness of the drug, including as compared to possible alternatives;

 

the ability of patients and physicians and other providers to obtain and maintain coverage and adequate reimbursement, if any, by third-party payers, including government payers;

 

the ability and desire of group purchasing organizations, or GPOs, including distributors and other network providers, to sell the drug to their constituencies;

 

introduction of counterfeit or unauthorized versions of the drug;

 

to the extent the drug is approved and marketed in a jurisdiction with a significantly lower price than in another jurisdiction, the impact of the lower pricing in the higher-priced territory, including on the pricing of reimbursement, if available, and by the diversion of lower-priced of the drug into the higher-priced territory; and

 

the availability of adequate commercial manufacturing and supply chain for the drug.

Our drugs may not be commercially successful if not widely covered and adequately reimbursed by third-party payers, and we may depend on others to obtain and maintain third-party payer access; inadequate third-party coverage and reimbursement could make entering into agreements with pharmaceutical companies to collaborate or commercialize our drugs more difficult and diminish our revenues.

Our and our collaborators’ and licensee’s ability to successfully commercialize any of our drugs that have been or may be approved will depend, in part, on government regulation and the availability of coverage and adequate reimbursement from third-party payers, including private health insurers and government payers, such as the Medicaid and Medicare programs, increases in government-run, single-payer health insurance plans, and compulsory licenses of drugs. We expect government and third-party payers will continue their efforts to contain healthcare costs by limiting coverage and reimbursement levels for new drugs. In addition, many countries outside of the U.S. have nationalized healthcare systems in which the government pays for all such products and services and must approve product pricing, and some U.S. politicians advocate for implementation of a comparable system in the United States. A government or third-party payer decision not to approve pricing, or provide adequate coverage and reimbursements, for our drugs, if any, could limit market acceptance of and demand for our drugs.

It is increasingly difficult to obtain coverage and adequate reimbursement levels from third-party payers, and significant uncertainty exists as to the coverage and reimbursement of newly approved prescription drug products. We or our collaborators also face competition in negotiating for coverage from pharmaceutical companies and others with competitive drugs or other treatment, and these competitors may have significantly more negotiating leverage or success with respect to individual payers than we or our collaborators may have.

Federal and state healthcare reform measures that have been or may be implemented in the future may result in more rigorous coverage criteria, more limited coverage, and downward pressure on the price that we may receive for any approved product, which could seriously decrease our future revenues. The Patient Protection and Affordable Care Act, as amended, or the ACA, which was enacted in 2010, is one such healthcare reform measure that has made a number of substantial changes in the way healthcare is financed by both governmental and private insurers. In the years since its enactment, there have been, and continue to be, significant developments in, and continued legislative, executive, and judicial activity around, attempts to repeal, replace, or modify the ACA. While Congress has not passed comprehensive repeal legislation, several bills affecting the implementation of certain taxes under the ACA have been signed into law. The TCJA includes a provision repealing, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA 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”. Additionally, the 2020 federal spending package permanently eliminated, effective January 1, 2020, the ACA-mandated “Cadillac” tax on high-cost employer-sponsored health coverage and medical device tax and, effective January 1, 2021, also eliminated the health insurer tax. Further, the Bipartisan Budget Act of 2018, or the BBA, among other things, amended the ACA, effective January 1, 2019, to increase from 50 percent to 70 percent the point-of-sale discount that is owed by pharmaceutical manufacturers who participate in Medicare Part D and to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”. In December 2018, the United States Department of Health and Human Services’ Centers for Medicare & Medicaid Services, or CMS, published a new final rule permitting further collections and payments to and from certain ACA qualified health plans, or QHPs, and health insurance issuers under the ACA risk adjustment program in response to the outcome of federal district court litigation regarding the method CMS uses to determine this risk adjustment. On April 27, 2020, the United States Supreme Court reversed a Federal Circuit decision that previously upheld Congress’s

29


 

denial of $12 billion in "risk corridor" funding. On December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of the TCJA. On December 18, 2019, the U.S. Court of Appeals for the Fifth Circuit upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District Court to determine whether the remaining provisions of the ACA are invalid as well. The United States Supreme Court is currently reviewing this case, but it is unknown when a decision will be made. Although the U.S. Supreme Court has not yet ruled on the constitutionality of the ACA, on January 28, 2021, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through May 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructs 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 ACA. It is unclear how the Supreme Court ruling, other such litigation, and the healthcare reform measures of the Biden administration will impact the ACA and our business and operations.

In addition, there has been heightened scrutiny in the United States and other countries of pharmaceutical pricing practices in light of the rising cost of prescription drugs and biologics. In the United States, such scrutiny has resulted in congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. Further, the Trump administration’s budget proposal for fiscal year 2021 included a $135 billion allowance to support legislative proposals seeking to reduce drug prices, increase competition, lower out-of-pocket drug costs for patients, and increase patient access to lower-cost generic and biosimilar drugs. On March 10, 2020, the Trump administration sent “principles” for drug pricing to Congress, calling for legislation that would, among other things, cap Medicare Part D beneficiary out-of-pocket pharmacy expenses, provide an option to cap Medicare Part D beneficiary monthly out-of-pocket expenses, and place limits on pharmaceutical price increases. On July 24, 2020 and September 13, 2020, President Trump announced several executive orders related to prescription drug pricing that seek to implement several of the administration’s proposals. The FDA also released a final rule on September 24, 2020 providing guidance for states to build and submit importation plans for drugs from Canada. Further, on November 20, 2020, HHS finalized a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, as well as a safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers. On November 20, 2020, CMS issued an interim final rule implementing President Trump’s Most Favored Nation executive order, which would tie Medicare Part B payments for certain physician-administered drugs to the lowest price paid in other economically advanced countries, effective January 1, 2021. On December 28, 2020, the United States District Court in Northern California issued a nationwide preliminary injunction against implementation of the interim final rule. However, it is unclear whether the Biden administration will work to reverse these measures or pursue similar policy initiatives. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. It is possible that additional governmental action is taken in response to the COVID-19 pandemic. For example, the CARES Act and other COVID-19 relief legislation suspended the 2% Medicare rate reduction sequester from May 1, 2020 through March 31, 2021, and extended the sequester by one year, through 2030. Further, on August 6, 2020, the Trump administration issued another executive order that instructs the federal government to develop a list of “essential” medicines and then buy them and other medical supplies from U.S. manufacturers instead of from companies around the world, including China. The order is meant to reduce regulatory barriers to domestic pharmaceutical manufacturing and catalyze manufacturing technologies needed to keep drug prices low and the production of drug products in the United States.

Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of additional cost containment measures or other healthcare reforms may also limit our commercial opportunities by reducing the amount a potential collaborator or licensee is willing to pay to license our programs or drug candidates in the future, which may prevent us from being able to establish and maintain collaborations and license agreements, generate revenue, attain profitability, or commercialize our products.

In the European Union, similar political, economic and regulatory developments may affect our ability to profitably commercialize our product candidates, if approved. In addition to continuing pressure on prices and cost containment measures, legislative developments at the European Union or member state level may result in significant additional requirements or obstacles that may increase our operating costs. The delivery of healthcare in the European Union, including the establishment and operation of health services and the pricing and reimbursement of medicines, is almost exclusively a matter for national, rather than European Union, law and policy. National governments and health service providers have different priorities and approaches to the delivery of healthcare and the pricing and reimbursement of products in that context. In general, however, the healthcare budgetary constraints in most European Union member states have resulted in restrictions on the pricing and reimbursement of medicines by relevant health

30


 

service providers. Coupled with ever-increasing European Union and national regulatory burdens on those wishing to develop and market products, this could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect our ability to commercialize our product candidates, if approved.

In markets outside of the United States and the European Union, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific products and therapies.

Certain Governments outside of the United States impose strict price controls, which may adversely affect our revenues, if any.

In some countries, particularly the countries of the European Union, the pricing of prescription pharmaceuticals is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidate to other available therapies. If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be harmed, possibly materially.

Forecasting potential sales for drugs will be difficult, and if our projections are inaccurate, our business and stock price may be adversely affected.

Our business planning requires us to forecast or make assumptions regarding demand and revenues for our drugs if they are approved, despite numerous uncertainties. These uncertainties may be increased if we rely on our collaborators to conduct commercial activities and provide us with accurate and timely information. Actual results may deviate materially from projected results for various reasons, including the following, as well as risks identified in other risk factors:

 

the rate of adoption in the particular market, including fluctuations in demand for various reasons, such as fluctuations related to economic changes, national and world events, holidays, and seasonal changes;

 

pricing (including discounting or other promotions), reimbursement, product returns or recalls, competition, labeling, DEA scheduling, adverse events, and other items that impact commercialization;

 

lack of patient and physician familiarity with the drug;

 

lack of patient use and physician prescribing history;

 

lack of commercialization experience with the drug;

 

actual sales to patients may significantly differ from expectations based on sales to wholesalers;

 

uncertainty relating to when the drug may become commercially available to patients and rate of adoption in other territories; and

 

other changes in regulatory or commercial conditions.

Revenues from drug sales may be based in part on estimates, judgment, and accounting policies, and incorrect estimates or regulators’ or others’ disagreement regarding such estimates or accounting policies may result in changes to guidance, projections, or previously reported results. Expected and actual product sales and quarterly and other results may greatly fluctuate, and such fluctuations can adversely affect the market price of our common stock, perceptions of our ability to forecast demand and revenues, and our ability to maintain and fund our operations.

Our efforts will be seriously jeopardized if we are unable to attract and retain key and other employees.

Our success depends on the continued contributions of our principal management, development, and scientific personnel and the ability to hire and retain key and other personnel. We face competition for such personnel, and we believe that risks and uncertainties related to our business may impact our ability to hire and retain key and other personnel. If we do not recruit and retain effective management and other key employees, particularly our executive officers, our operations, our ability to generate or raise additional capital, and our business in general, may be adversely impacted. For example, to execute our clinical programs, our strategy is to maintain a sufficient and robust program management function with clinical expertise. We are in the process of modifying and building this function, and we may not be able to establish the function we believe necessary to support our clinical goals and meet our corporate objectives.

31


 

We are expanding our organization and may experience difficulties in managing this growth, which could disrupt our operations.

Although we reduced our recruiting and hiring activities in light of the ongoing COVID-19 pandemic, as part of our long-term business plan, we are seeking to expand our employee base to increase our managerial, scientific, operational, manufacturing supply, commercial, financial, and other resources and to hire more consultants and contractors, including in and outside of our office locations. Future growth will impose significant additional responsibilities on our management, including the need to identify, recruit, maintain, motivate and integrate additional employees, consultants and contractors. Also, our management may need to divert attention away from our day-to-day activities and devote a substantial amount of time to managing these growth activities. We may not be able to effectively manage the expansion of our operations, which may result in weaknesses in our infrastructure, give rise to operational mistakes, loss of business opportunities, loss of employees, and reduced productivity among remaining employees. Our future growth could require significant capital expenditures and may divert financial resources from other projects, such as the development of additional product candidates. Moreover, if our management is unable to effectively manage our growth, our expenses may increase more than expected, our ability to generate and/or grow revenues could be reduced, and we may not be able to implement our business strategy. Our future financial performance and our ability to develop and then commercialize any approved products and compete effectively will depend, in part, on our ability to effectively manage any future growth.

Data generated or analyzed with respect to product use in the market or required postmarketing or other studies or trials may result in decreased demand, lower sales, product recall, regulatory action, or litigation.

An NDA holder (or the equivalent outside the United States) is responsible for assessing and monitoring the safety of a drug that has been approved for marketing, including reviewing reports of adverse safety events. In addition, NDA holders often conduct additional studies or trials or analyze new or previous data related to an approved drug, including with respect to required postmarketing studies and in connection with seeking additional regulatory approvals in new territories.

Any new data generated, including from adverse event reports or required postmarketing, registration, or other studies or trials, may result in label changes, adversely affect sales or development, result in withdrawal of the drug from the market, or result in litigation. In addition, analyses of previous data can have similar risks. Regulatory agencies may consider the new data or analyses in reviewing marketing applications for drug candidates in their territories or impose post-approval requirements that require significant additional expenditures. For example, in February 2020, the FDA requested that Eisai withdraw lorcaserin (previously marketed in the United States as BELVIQ and BELVIQ XR) from the U.S. market based on the FDA’s analysis of data from a study completed by Eisai and a change in the FDA’s risk-benefit assessment of BELVIQ, and regulators in other countries have taken similar steps. Eisai agreed to voluntarily withdraw lorcaserin products from the U.S. market, as requested by the FDA, and from foreign markets. Following these events, lawsuits relating to lorcaserin against us and others have been filed in the United States and abroad. While these lawsuits remain in preliminary stages and we are actively disputing the allegations contained therein, to the extent they proceed, and the claims they allege are found to have merit and an adverse judgment ensues, the lawsuits may have a material adverse effect on our business or financial condition.

The discovery of significant problems with a product or class of products similar to any approved drug could have an adverse effect on our or our collaborator’s or licensee’s commercialization.

If we license or otherwise partner our drugs, our failure to maintain such agreements or poor performance or results under such agreements could negatively impact our business.

Our collaborators and licensees may have primary responsibility for the regulatory approval, marketing, distribution, and, in certain circumstances, development, of our drug candidate(s) in the territory or territories under the applicable collaboration. We may have limited or no control over our collaborator’s decisions, including the amount and timing of resources that any of these collaborators will dedicate to such activities. This is the case for our ralinepag exclusive license agreement with United Therapeutics and our lorcaserin Transaction Agreement with Eisai.

When we enter collaboration and license agreements, we are subject to a number of other risks, including:

 

our collaborators and licensees may not comply with applicable laws or regulatory guidelines, which could adversely impact the development or commercialization of the drug or drug candidate;

 

there could be disagreements regarding the agreements or the study or development that delay or terminate the commercialization, research, study, or development, delay or eliminate potential payments under the agreements, or increase our costs under or outside of the agreements;

32


 

 

our collaborators and licensees may not effectively allocate adequate resources, may have limited experience in a particular territory, or may generate unfavorable data or results; and

 

our collaborators and licensees may not perform as expected, including with regard to making any required payments, and the agreements may not provide adequate protection or may not be effectively enforced.

We or our collaborators or licensees might terminate our agreements in certain circumstances or amend the terms of our agreement, and investors and analysts may not view any termination or amendment as favorable.

We rely on other companies, including third-party manufacturers and sole-source suppliers, to manufacture all our drugs and drug candidates, and we or such other companies may encounter failures or difficulties or not receive or provide adequate supply, which could adversely affect development or commercialization.

We do not own or operate manufacturing facilities that can produce active pharmaceutical ingredient, or API, intermediates, and other material required to make our drug candidates. Instead, we rely on other companies to supply API, intermediates, and other materials. Certain of these materials are available from only one or a small number of suppliers, and using a new supplier, if available, could result in substantial delay and greater cost. Our and our manufacturers’ dependence on single or limited sources of materials may adversely affect our ability to develop and deliver drug products on a timely and competitive basis, or at all.

Any performance failure on the part of us or a third-party manufacturer could result in a product recall or seizure or a delay or other adverse effect on sales of an approved product or the clinical development or regulatory approval of one or more of our other drug candidates. We or third-party manufacturers may encounter difficulties involving production yields, regulatory compliance, lot release, quality control, and quality assurance, as well as shortages of qualified personnel.

The ability to adequately and timely manufacture and supply drug product is dependent on the uninterrupted and efficient operation of the manufacturing facilities, which is impacted by many manufacturing variables, including:

 

availability or contamination of raw materials and components used in the manufacturing process, particularly those for which we have no other source or supplier;

 

ability to accommodate changes in dosage or formulation;

 

capacity of our facilities or those of our contract manufacturers;

 

having the ability to adjust to changes in actual or anticipated use of the facility, including with respect to having sufficient capacity and a sufficient number of qualified personnel;

 

facility contamination by microorganisms or viruses or cross contamination;

 

compliance with regulatory requirements, including inspectional notices of violation and warning letters;

 

maintenance and renewal of any required licenses or certifications;

 

changes in actual or forecasted demand;

 

timing and number of production runs;

 

production success rates and bulk drug yields; and

 

timing and outcome of product quality testing.

In addition, we or our third-party manufacturers may encounter delays and problems in manufacturing our drug candidates or drugs for a variety of reasons, including accidents during operation, failure of equipment, delays in receiving materials, natural or other disasters, health epidemics (including COVID-19), political or governmental unrest or changes, social unrest, intentional misconduct, or other factors inherent in operating complex manufacturing facilities. Commercially available starting materials, reagents and excipients may be or become scarce or more expensive to procure, and we may not be able to obtain favorable terms in agreements with subcontractors. We or our third-party manufacturers may not be able to operate our respective manufacturing facilities in a cost-effective manner or in a time frame that is consistent with our expected future manufacturing needs. If we or our third-party manufacturers cease or interrupt production or if our third-party manufacturers and other service providers fail to supply materials, products, or services to us for any reason, such interruption could delay progress on our programs, or interrupt the commercial supply of drug products, with the potential for additional costs and lost revenues. If this were to occur, we may also need to seek alternative means to fulfill our manufacturing needs.

We may not be able to enter into or maintain agreements with manufacturers whose facilities and procedures comply with applicable law. Manufacturers are subject to ongoing periodic inspection (which may be unannounced) by the FDA, the DEA,

33


 

corresponding state and foreign authorities and other regulatory authorities to ensure strict compliance with Current Good Manufacturing Practices, or cGMPs, regulations, and other applicable government regulations and corresponding foreign standards. We do not have control over a third-party manufacturer’s compliance with these regulations and standards. If we or one of our manufacturers or other company in the supply chain fail to maintain compliance or otherwise experience setbacks, we or they could be subject to civil or criminal penalties, the production of one or more of our drug candidates or any approved products could be interrupted or suspended, or our product could be recalled or withdrawn, resulting in delays, additional costs, and potentially lost revenues.

Our drug candidates are subject to extensive regulation, and we may not receive required regulatory approvals, or timely approvals, for any of our drug candidates.

Preclinical and clinical development, manufacturing, labeling, packaging, storage, recordkeeping, advertising, promotion, export, marketing and distribution, and other activities relating to developing and manufacturing drugs are subject to extensive regulation by the FDA, EMA and other regulatory agencies. We and others we contract with are subject to periodic inspections (which may be unannounced) by the FDA, the DEA, EMA and other regulatory agencies. Failure to comply with applicable regulatory requirements may, either before or after product approval, subject us to administrative or judicially imposed sanctions that may negatively impact research and development or commercialization, or otherwise negatively impact our business. Regulatory agencies have in the past inspected certain aspects of our business, and we were provided with observations of objectionable conditions or practices with respect to our business. There is no assurance that regulatory agencies will not provide us with observations in future inspections or that we satisfactorily addressed observations provided to us in past inspections.

Regulatory approval of a drug candidate is not guaranteed, and our business and reputation may be harmed by any failure or significant delay in receiving regulatory approval. The number and types of preclinical studies and clinical trials that will be required for FDA approval varies depending on the drug candidate, the disease or condition that the drug candidate is designed to target and the regulations applicable to any particular drug candidate. Despite the time and expense exerted in preclinical and clinical studies, failure can occur at any stage, and we could encounter problems that cause us to abandon clinical trials or to repeat or perform additional preclinical studies and clinical trials.

We cannot predict when or whether, or assure you that, our collaborators’ or our past or any future regulatory submissions or responses will be sufficient to the applicable regulatory authority or others, that the applicable regulatory authority or others will consider data or our analyses, interpretations or procedures related to any of our drug candidates as sufficient or persuasive, or that any regulatory authority will ever approve any of our drug candidates in the future.

To market any drugs outside of the United States, we and our current or future collaborators must comply with numerous and varying regulatory requirements of other countries. Approval procedures vary among countries and can involve additional product testing and additional administrative review periods. The time required to obtain approval in other countries might differ from that required to obtain FDA approval. The regulatory approval process in other countries may include all of the risks associated with FDA approval as well as additional risks, some of which may be unanticipated. In addition, in many countries outside the United States, it is required that the product be approved for reimbursement before the product can be approved for sale in that country. We or these third parties may not obtain approvals from regulatory authorities outside the United States on a timely basis, if at all. Approval by the FDA or any other regulatory authority does not assure or predict with any certainty that any other regulatory authority will approve the drug. The failure to obtain approval in one jurisdiction may negatively impact our ability to obtain approval elsewhere. We may not be able to file for marketing approvals and may not receive necessary approvals to commercialize our products in any jurisdiction, which could materially impair our ability to generate revenue. In addition, existing regulatory policies and laws may change. We cannot predict the likelihood, nature, or extent of new government regulation, either in the United States or in other countries, or the impact on our drug candidates or drugs. For example, new FDA regulation could delay or prevent marketing approvals, increase the cost of research and development, and result in narrower product labeling and expensive post-marketing requirements.

Fast Track, Breakthrough Therapy, Accelerated Approval, Priority Review, or similar designations by the FDA or other applicable regulatory agencies may not lead to a faster development or review process.

The FDA may grant Fast Track, Breakthrough Therapy, Accelerated Approval, Priority Review, or other designations to product candidates that meet applicable guidelines in order to speed the availability of certain drugs. Other applicable regulatory agencies may grant similar designations. These designations may apply only to the combination of a product candidate and a specific indication or patient population. Product candidates that receive these designations may not actually receive faster clinical development or regulatory review or approval any sooner than other product candidates that do not have such designation, or at all. Furthermore, a product’s receipt of such a designation does not increase the likelihood that the product candidate will receive marketing approval. The FDA or other regulatory agency may also withdraw a designation if it determines that the product candidate no longer meets the relevant criteria.

34


 

For example, the FDA has granted Fast Track designation for APD418 for treatment of decompensated heart failure, or DHF, which we refer to as acute heart failure, or AHF, in patients who have heart failure with reduced ejection fraction, or HFrEF, and for temanogrel for improvement of cardiovascular outcomes and myocardial recovery by the prevention and treatment of microvascular obstruction (MVO) in patients undergoing percutaneous coronary intervention (PCI). Despite receiving these Fast Track designations, such designations may be withdrawn in the future, and in any event APD418 and temanogrel may not actually receive faster clinical development or regulatory review or approval any sooner than other product candidates that do not have such designation, or at all.

Our activities and drugs will still be subject to extensive postmarketing regulation if approved.

Following regulatory approval of any of our drug candidates, we and our collaborators will be subject to ongoing obligations and continued regulatory review from the FDA, EMA and other applicable regulatory agencies, such as continued adverse event reporting requirements. There may also be additional postmarketing obligations imposed by the FDA, EMA or other regulatory agencies. These obligations may result in significant expense and limit the ability to commercialize such drugs.

The FDA, EMA or other regulatory agencies may also require that the sponsor of the NDA or foreign equivalent, as applicable, conduct additional clinical trials to further assess approved drugs after approval under a post-approval commitment. Such additional studies may be costly and may impact the commercialization of the drug. Unfavorable trial results from postmarketing studies could negatively impact market acceptance of the drug, limit the revenues we generate from sales, result in the drug’s withdrawal from the market, negatively impact the potential approval of the drug in other territories, and result in litigation.

The FDA, EMA or other regulatory agencies may also impose significant restrictions on the indicated uses for which a drug may be marketed. Additionally, the FDA may require a Risk Evaluation and Mitigation Strategies, or REMS, program, including in connection with a drug’s approval, to help ensure that the benefits of the drug outweigh its risks. A REMS 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, limitations on who may prescribe or dispense the drug, requirements that patients enroll in a registry or undergo certain health evaluations, or other measures that the FDA deems necessary to ensure the safe use of the drug.

With regard to any drug that receives regulatory approval, the labeling, packaging, adverse event reporting, storage, advertising, and promotion for the drug will be subject to extensive regulatory requirements. We and the manufacturers of our products are also required to comply with cGMP regulations, which include requirements relating to quality control and quality assurance, as well as the corresponding maintenance of records and documentation. Further, regulatory agencies must approve these manufacturing facilities before they can be used to manufacture our products, and these facilities are subject to ongoing regulatory inspections. In addition, regulatory agencies subject a drug, its manufacturer, and the manufacturer’s facilities to continual review and inspections. The subsequent discovery of previously unknown problems with a drug, including adverse events of unanticipated severity or frequency, or problems with the facility where the drug is manufactured, may result in restrictions on the marketing of that drug, up to and including withdrawal of the drug from the market. In the United States, the DEA and comparable state-level agencies also heavily regulate the manufacturing, holding, processing, security, recordkeeping, and distribution of drugs that are considered controlled substances, and the DEA periodically inspects facilities for compliance with its rules and regulations.

Our ability to generate revenues from any of our drugs that receive regulatory approval will be subject to a variety of risks, many of which are out of our control.

Despite having been approved for marketing by a regulatory agency, a drug may not gain market acceptance among patients, healthcare providers, healthcare payers or the medical community. We believe that the degree of market acceptance and our ability to generate revenues from such products will depend on a number of factors, including:

 

timing of market introduction of our drugs and competitive drugs and alternative treatments;

 

physician and patient awareness of our drugs;

 

actual and perceived efficacy and safety of our drugs;

 

incidence and severity of any side effects;

 

potential or perceived advantages or disadvantages as compared to alternative treatments;

 

effectiveness of sales, marketing and distribution support;

 

price of our future products, both in absolute terms and relative to alternative treatments;

 

the general marketplace for the particular drug;

 

the effect of current and future healthcare laws on our drug candidates;

35


 

 

 

availability of coverage and adequate reimbursement from government and other third-party payers; and

 

product labeling or product insert requirements of the FDA or other regulatory authorities.

If our approved drugs fail to achieve market acceptance, we may not be able to generate significant revenues to be profitable.

Collaboration and license agreement relationships may lead to disputes, divert management’s attention, expose us to liability, and delay drug development and commercialization, and we may not realize the full commercial potential of our drug candidates or drugs.

We may have conflicts with our prospective, current, or past collaborators or licensees, such as conflicts concerning rights and obligations under our agreements (including, for example, relating to indemnification for product liability claims and losses), the interpretation of preclinical or clinical data, the achievement of milestone or other payments, the ownership of intellectual property, or research and development, regulatory, commercialization, litigation, or other strategy. Collaborators or licensees may stop supporting our drug candidates or drugs, including if they no longer view the program as in their best financial or other interests or they develop or obtain rights to competing drug candidates or drugs. In addition, collaborators or licensees may fail to effectively develop, obtain approval for, or commercialize our drugs, which may result in us not realizing their full commercial potential. If any conflicts arise with any of our current, past, or prospective collaborators or licensees, the other party may act in a manner that is adverse to our interests. Any such disagreement could result in one or more of the following, each of which could delay, or lead to termination of, development or commercialization of our drug candidates or drugs, and in turn prevent us from generating revenues or cause us to incur liabilities:

 

unwillingness or inability on the part of a collaborator or licensee to pay for studies or other research, milestones, royalties or other payments that we believe are due to us under a collaboration;

 

uncertainty regarding ownership of intellectual property rights arising from our collaboration or license agreement activities, which could prevent us from entering into additional collaborations;

 

unwillingness on the part of a collaborator or licensee to keep us informed regarding the progress of its development, regulatory, commercialization, pharmacovigilance, or other activities or to permit public disclosure of the results of those activities;

 

slowing or cessation of a collaborator’s or licensee’s research, development, regulatory, or commercialization efforts with respect to our drug candidates or drugs; or

 

litigation or arbitration with our collaborator or licensee, or with third parties (including relating to product liability, intellectual property, or other subject matters).

Setbacks and consolidation in the pharmaceutical and biotechnology industries could make entering into agreements with pharmaceutical companies to collaborate or commercialize our drugs more difficult and diminish our revenues.

Setbacks in the pharmaceutical and biotechnology industries, such as those caused by safety concerns relating to drugs or drug candidates, as well as competition from generic drugs, litigation and industry consolidation, may have an adverse effect on us, including by making it more difficult to enter into agreements with pharmaceutical companies to collaborate or commercialize our drugs and diminishing our revenues. For example, the FDA may be more cautious in approving our drug candidates based on safety concerns relating to these or other drugs or drug candidates, or pharmaceutical companies may be less willing to enter into new collaborations or continue existing collaborations if they are integrating a new operation as a result of a merger or acquisition or if their therapeutic areas of focus change following a merger.

We and our collaborators rely on third parties to conduct clinical trials and preclinical studies. If those parties do not comply with regulatory and contractual requirements, successfully carry out their contractual obligations, or meet expected deadlines, our drug candidates may not advance in a timely manner or at all.

In the course of our discovery, preclinical testing, and clinical trials, we and our collaborators rely on third parties, including investigators, clinical research organizations, manufacturers, and laboratories, to perform critical services. For example, we rely on third parties to conduct our clinical trials and many of our preclinical studies. Clinical research organizations are responsible for many aspects of the trials, including finding and enrolling participants for testing and administering the trials. Although we rely on these third parties to conduct our clinical trials, we are responsible for ensuring that each of our clinical trials is conducted in accordance with its investigational plan and protocol. Moreover, the FDA and foreign regulatory authorities require us to comply with regulations and standards, commonly referred to as Good Clinical Practices, or GCPs, for conducting, monitoring, recording, and reporting the results of clinical trials to ensure that the data and results are scientifically credible and accurate and that the trial participants are adequately informed of the potential risks of participating in clinical trials. Our reliance on third parties does not relieve us of these

36


 

responsibilities and requirements. These third parties may not be available when we need them or, if they are available, may not comply with all legal, regulatory, and contractual requirements or may not otherwise perform their services in a timely or acceptable manner, and we may need to enter into new arrangements with alternative third parties, and our preclinical studies or clinical trials may be extended, delayed, or terminated. These independent third parties may also have relationships with other commercial entities, some of which may compete with us. In addition, if such third parties fail to perform their obligations in compliance with legal and regulatory requirements and our protocols, our preclinical studies or clinical trials may not meet regulatory requirements or may need to be repeated. As a result of our dependence on third parties, we may face delays or failures outside of our direct control. These risks also apply to the development activities of collaborators, and we do not control their research and development, clinical trial, or regulatory activities.

We may participate in new strategic transactions that could impact our liquidity, increase our expenses, present significant distractions to our management, and be viewed as unfavorable.

From time to time we consider strategic transactions, such as out-licensing or in-licensing of compounds or technologies, acquisitions of companies, asset purchases, and spin-offs. Additional potential transactions we may consider include a variety of different business arrangements, such as strategic collaborations, joint ventures, restructurings, divestitures, business combinations, and investments. In addition, another entity may pursue us as an acquisition target. Any such transaction may be viewed as unfavorable by our stockholders or others and may require us to incur non-recurring or other charges, may create potential liabilities, may increase our near- and long-term expenditures, and may pose significant integration challenges, require additional expertise, or disrupt our management or business, any of which could harm our operations and financial results.

When we evaluate significant proposed transactions we conduct business, legal, and financial due diligence with the goal of identifying and evaluating material risks involved in the transaction. Despite our efforts, we ultimately may be unsuccessful in ascertaining or evaluating all such risks and, as a result, might not realize the intended advantages of the transaction. If we fail to realize the expected benefits from any transaction we may consummate, whether as a result of unidentified risks, integration difficulties, regulatory setbacks, or other events, our business, results of operations, and financial condition could be adversely affected.

We may incur substantial liabilities for any product liability claims or otherwise as a drug product developer.

We develop, test, manufacture, and expect to commercialize drugs for use by humans. We face an inherent risk of product liability exposure related to the testing of our drug candidates in clinical trials, and a risk with the commercialization of lorcaserin (previously marketed in the United States as BELVIQ and BELVIQ XR) as well as any other drug that may be approved for marketing.

Whether or not we are ultimately successful in any product liability or related litigation, such litigation would consume substantial amounts of our financial and managerial resources and might result in adverse publicity, all of which would impair our business. In addition, damages awarded in a product liability action could be substantial and could have a negative impact on our financial condition.

An individual may bring a liability claim against us if one of our drugs or drug candidates causes, or merely appears to have caused, an injury. Regardless of merit or eventual outcome, liability claims may result in:

 

decreased demand for our drug;

 

injury to our reputation;

 

increased difficulty to attract, or withdrawal of, clinical trial participants;

 

costs of related litigation;

 

substantial monetary awards to clinical trial participants, patients, or other claimants;

 

loss of revenues; and

 

the inability to commercialize our drugs or drug candidates.

We have limited product liability insurance that covers our clinical trials and products as well as indemnification protection in certain of our collaboration or license agreements. Our insurance costs continue to rise, and we may not be able to maintain or obtain insurance coverage at a reasonable cost, we may not have insurance coverage that will be adequate to satisfy any liability that may arise, and our collaborators or licensees may not indemnify us, each of which could have an adverse effect on our results of operations and financial condition.

37


 

For example, in December 2016 we granted Eisai an exclusive, royalty-bearing license, or transferred intellectual property, to develop, manufacture, and commercialize lorcaserin (previously marketed in the United States as BELVIQ and BELVIQ XR) in all countries and territories of the world. Our former subsidiary Arena Pharmaceuticals GmbH, or Arena GmbH, manufactured BELVIQ and other products for commercialization or clinical trials up until the sale of that manufacturing business to Siegfried effective March 31, 2018. Under our agreements with Eisai, we and Eisai will each bear 50% of losses arising from any alleged defective manufacturing of BELVIQ by Arena GmbH prior to the date of the sale to Siegfried, and Eisai will be solely responsible for any expenses and losses associated with other product liability claims. In February 2020, the FDA requested that Eisai withdraw lorcaserin products from the U.S. market based on the FDA’s analysis of data from a study completed by Eisai and a change in the FDA’s risk-benefit assessment of lorcaserin, and regulators in other countries have taken similar steps. Eisai agreed to voluntarily withdraw lorcaserin products from the U.S. market, as requested by the FDA, and from foreign markets. Following these events, lawsuits relating to lorcaserin against us and others have been filed in the United States and abroad. Any damages awarded in connection with lorcaserin litigation could be substantial and have a negative impact on our financial condition. Eisai or others could also take the position that some or all claims fall outside their indemnification obligations, or they could be unable to indemnify us, in connection with litigation or other claims, and seeking to enforce rights to indemnification could require significant financial resources and management attention. Even if we are successful in defending against all claims or are fully indemnified or insured, such claims could still consume significant financial resources, divert attention away from our day-to-day activities, and result in adverse publicity, all of which could have a negative impact on our financial condition and our business.

We have significant contractual obligations that may adversely affect our cash flow, cash position, and stock price.

We have long-term leases on real properties and other contractual obligations, and limited revenues. If we are unable to generate cash from operations in the future sufficient to meet our financial obligations we will need to obtain additional funds from other sources, and we may not be able to do so at all or on terms favorable to our stockholders or us.

Also, if we do not have sufficient cash in the future and are unable to generate cash from operations or obtain additional funds from other sources sufficient to meet our contractual obligations, we may have to delay or curtail some or all of our development and commercialization programs, sell or license some or all of our assets on terms that you or others may view as unfavorable, or default on obligations under our agreements.

We may be subject, directly or indirectly, to federal, state, and international healthcare laws and regulations, including but not limited to fraud and abuse and false claims laws. If we are unable to comply, or have not fully complied, with such laws or regulations, we could face substantial penalties and prosecution.

In the United States, drug manufacturers and marketers are subject to various state and federal fraud and abuse laws, including, without limitation, the Federal Anti-Kickback Statute and Federal False Claims Act. There are similar laws in other countries. These laws may impact, among other things, the research, manufacturing, sales, marketing, and education programs for our drugs.

The Federal Anti-Kickback Statute prohibits persons and entities from knowingly and willingly soliciting, offering, receiving, or providing any remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the purchase, lease, order, or furnishing or arranging for, a good, item, facility, or service, for which payment may be made, in whole or in part, under a federal healthcare program such as the Medicare and Medicaid programs. 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. The Federal Anti-Kickback Statute is broad and, despite a series of narrow statutory exceptions and regulatory safe harbors, prohibits many arrangements and practices that are lawful in businesses outside of the healthcare industry. Moreover, the ACA, among other things, amended the intent requirement of the Federal Anti-Kickback Statute and certain criminal healthcare fraud statutes. A person or entity no longer needs to have actual knowledge of these statutes or specific intent to violate them. The ACA also provides that the government may assert that a claim including items or services resulting from a violation of the Federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the Federal Civil False Claims Act. Many states have also adopted laws similar to the Federal Anti-Kickback Statute, some of which apply to the referral of patients for healthcare items or services reimbursed by any source, not only the Medicare and Medicaid programs.

The Federal Civil False Claims Act prohibits, among other things, persons or entities from knowingly presenting, or causing to be presented, a false claim to, or the knowing use of false statements to obtain payment from, the federal government. Suits filed under the Federal Civil False Claims Act can be brought by any individual on behalf of the government, known as “qui tam” actions, and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines or settlement. The filing of qui tam actions has caused a number of pharmaceutical, medical device, and other healthcare companies to have to defend a Federal Civil False Claims Act action. When an entity is determined to have violated the Federal Civil False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus civil penalties for each separate false claim, in addition to other penalties that may apply. Various states have also enacted laws modeled after the Federal Civil False Claims Act, some of which are broader in scope and may apply regardless of payer.

The Federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, created 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 payers, 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. Additionally, the civil monetary penalties statute imposes penalties against any person or entity that, among other things, 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 Physician Payments Sunshine Act, created under the ACA, and its implementing regulations require certain manufacturers of drugs, devices, biologicals, and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program (with certain exceptions) to report annually to the U.S. Department of Health and Human Services, or HHS, information related to payments or other transfers of value made to physicians (defined to include doctors, dentists, optometrists, podiatrists, and chiropractors) and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members. Beginning in 2022, applicable manufacturers also will be required to report such information regarding their transfers of value during the previous year to physician assistants, nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, anesthesiologist assistants, and certified nurse midwives.

We may be subject to healthcare data privacy and security regulation by both the federal government and the states in which we conduct our business. HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their respective implementing regulations, impose specified requirements on certain healthcare providers, health plans, and healthcare clearinghouses, known as covered entities, as well as their business associates and their covered subcontractors that perform services involving the use or disclosure of individually identifiable health information relating to the privacy, security, and transmission of individually identifiable health information. Further, we may also be subject to state health information privacy and data breach notification laws which govern the collection, use, disclosure, and protection of health-related and other personal information, many of which differ from each other in significant ways and often are not pre-empted by HIPAA, thus requiring additional compliance efforts.

Additionally, the Drug Supply Chain Security Act imposes obligations on manufacturers of pharmaceutical products, among others, related to product tracking and tracing. Among the requirements, manufacturers will be required to provide certain information regarding the drug product to individuals and entities to which product ownership is transferred, label drug product with a product identifier, and keep certain records regarding the drug product. The transfer of information to subsequent product owners by manufacturers will eventually be required to be done electronically. Manufacturers will also be required to verify that purchasers of the manufacturers’ products are appropriately licensed. Further, manufacturers will have drug product investigation, quarantine, disposition, and notification responsibilities related to counterfeit, diverted, stolen, and intentionally adulterated products, as well as products that are the subject of fraudulent transactions or which are otherwise unfit for distribution such that they would be reasonably likely to result in serious health consequences or death.

Outside the United States, interactions between pharmaceutical companies and physicians are also governed by strict laws, such as national anti-bribery and kickback laws of European countries, regulations, industry self-regulation codes of conduct, and physicians’ codes of professional conduct. Payments made to physicians in certain European Union Member States must be publicly disclosed. Moreover, agreements with physicians often must be the subject of prior notification and approval by the physician’s employer, his or her competent professional organization, and/or the regulatory authorities of the individual European Union Member States. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines, or imprisonment. Risks associated with these laws may increase as new laws and regulations are adopted and as enforcement agencies adopt or increase enforcement efforts.

We are unable to predict whether we could be subject to actions under any of these fraud and abuse or other laws, or the impact of such actions. If we are found to be in violation of any of the laws described above and other applicable federal, state and international laws, we may be subject to penalties, including significant civil, criminal and/or administrative penalties, damages, fines, individual imprisonment, disgorgement, possible exclusion from government healthcare reimbursement programs, integrity oversight and reporting obligations to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of our operations, all of which could have a material adverse effect on our business and results of operations.

We may be subject to a variety of laws regarding data privacy and protection, which carry potentially significant penalties for non-compliance.

Across the United States and globally, laws and regulations governing data privacy and security continue to develop and evolve. The data privacy and security laws and regulations to which we are subject may significantly impact our business activities. Many of the laws and regulations that apply to us contain ambiguous provisions or impose requirements that differ from country to country, creating uncertainty. Compliance with the enhanced obligations imposed by such laws and regulations may require us to revise our

39


 

business practices, allocate more resources to privacy and security, and implement new technologies. Such efforts may result in significant costs to our business.

For example, the European Union, Switzerland, and certain other foreign territories have restrictions on the transfer, use and maintenance of certain personal data, including providing that transfers of personal data outside of their territories may only take place if the country to which the personal data is transferred ensures an “adequate” level of privacy protection. The European Commission has previously found that the United States did not provide adequate levels of protection. In addition, the European Commission has approved a data protection regulation, known as the General Data Protection Regulation, or GDPR, which became effective on May 25, 2018. The GDPR contains provisions specifically directed at the processing of health information, higher sanctions and extra-territoriality measures intended to bring non-EU companies under the regulation. We conduct clinical trials in the European Union, and in the future we may expand our business operations to include additional operations in the European Union. With such expansion, we would be subject to increased governmental regulation, including the GDPR, in the EU countries in which we operate, including restrictions on data transfers that may negatively impact our ability and increase our costs to maintain international operations. Penalties for non-compliance with the GDPR are steep, with potential fines of up to 4% of our global revenue.

Additionally, the California Consumer Privacy Act, or CCPA, went into effect on January 1, 2020. The CCPA created new individual privacy rights for consumers (as that word is broadly defined in the law) and places increased privacy and security obligations on entities handling personal data of consumers or households. It requires covered companies to provide new disclosures to California consumers, provide such consumers new ways to opt-out of certain sales of personal information, and allow for a new cause of action for data breaches. The CCPA may impact our business activities and exemplifies the vulnerability of our business to not only cyber threats but also the evolving regulatory environment related to personal data and protected health information.

Failure to comply with data privacy and security laws and regulations could result in regulatory penalties and significant legal liability and could have a material adverse impact on our financial results.

We may not be able to effectively integrate, manage or maintain our international operations, and such difficulty could adversely affect our business operations, financial condition, results of operations and stock price.

We have personnel in Switzerland, and we engage in clinical trials and other activities in many territories outside of the United States. There are significant risks associated with foreign operations, including but not limited to:

 

compliance with various local laws and regulations, which may conflict or change, such as privacy regulations, tax laws, export and import restrictions, employment laws, regulatory requirements, and other governmental approvals, permits, and licenses;

 

complexities and difficulties in obtaining protection for and enforcing our intellectual property rights;

 

difficulties in staffing and managing foreign operation, such as the integration of our corporate culture with local customs and cultures;

 

the distraction to our management;

 

foreign currency exchange rates and the impact of shifts in the United States and local economies on those rates;

 

certain expenses including, among others, expenses for travel, translation, and insurance; and

 

integration of our policies and procedures, including disclosure controls and procedures and internal control over financial reporting, with our international operations.

Any of these risks could adversely affect our business.

We and third parties we contract with use hazardous materials in our operations.

Our activities involve the use of materials that could be hazardous to human health and safety or the environment. We cannot completely eliminate the risks associated with their use, storage, or disposal, which could cause:

 

interruption of our development or manufacturing efforts;

 

injury to our employees and others;

 

environmental damage resulting in costly cleanup; and

 

liabilities under domestic or foreign laws and regulations governing the use, storage, handling, and disposal of these materials and specified waste products.

40


 

In such an event, we may be held liable for any resulting damages, and any such liability could exceed our resources. Although we carry insurance in amounts and type that we consider commercially reasonable, we cannot be certain that the coverage or coverage limits of our insurance policies will be adequate, and we do not have insurance coverage for losses relating to an interruption of our research and development efforts caused by contamination.

Our business, including our preclinical and clinical programs, may be significantly and adversely affected by the COVID-19 pandemic.

Coronavirus disease 2019, or COVID-19, has spread globally, including in the United States and Switzerland, where we have operations, and in many other countries where we are conducting or plan to conduct clinical trials or have manufacturing activities conducted. COVID-19 is impacting domestic and worldwide economic activity, including global financial markets on which we rely for financing to fund our operations. The COVID-19 pandemic poses the risk that we or our clinical trial participants, employees, contractors, collaborators and vendors may be prevented from conducting certain clinical trials or other business activities for an indefinite period of time, including due to “stay-at-home” orders or shutdowns that have been or may be requested or mandated by governmental authorities. Beginning the week of March 16, 2020, substantially all of our workforce began working from home either all or substantially all of the time. The pandemic, stay-at-home orders, and our work-from-home policies may negatively impact productivity, disrupt our business, and delay our development programs, all of which may delay our regulatory and commercialization timelines. The magnitude of these impacts will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course.

The COVID-19 pandemic has impacted and may continue to impact our clinical programs, including our etrasimod, olorinab, and APD418 programs. For example, some clinical site activations and participant enrollment and screening rates slowed for certain periods in certain regions. These timing changes, however, have been highly variable and their aggregate impact remains uncertain. As a result, it is not possible at this time to estimate the total impact COVID-19 will have on our clinical programs. If the COVID-19 pandemic continues in the United States and around the world, we may experience, or continue to experience, disruptions that could severely impact our preclinical studies and clinical trials, including:

 

delays in receiving approval from local regulatory authorities to initiate our planned clinical trials;

 

delays or difficulties in enrolling or retaining participants in our clinical trials;

 

delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff;

 

delays in clinical sites receiving the supplies and materials needed to conduct our clinical trials, including interruption in global shipping that may affect the transport of clinical trial materials;

 

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;

 

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 participant 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;

 

interruptions in preclinical studies due to restricted or limited operations at our research and development 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 employees;

 

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;

 

refusal of the FDA or other regulatory authorities to accept data from clinical trials in affected geographies; and

 

interruption or delays to our sourced discovery and clinical activities.

The COVID-19 pandemic continues to rapidly evolve. The extent to which the outbreak impacts our business, preclinical studies, and clinical programs will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the pandemic, stay-at-home orders, travel restrictions, and “social distancing” in the United States, Switzerland and other countries, business closures or business disruptions,

41


 

and the effectiveness of actions taken in the United States and other countries to contain and treat the disease and vaccinate their populations.

Our business and operations might be disrupted or adversely affected by catastrophic events and security breaches, including any cybersecurity incidents.

Our U.S. operations are primarily located in a business park in San Diego, California and an office in Boston, Massachusetts, and our principal executive offices are located in Park City, Utah. We also have certain operations in Zug, Switzerland. We depend on our facilities and on collaborators, licensees, contractors and vendors for the continued operation of our business, some of whom are located in Europe and Asia. As a result, natural disasters or other catastrophic events in various parts of the world, including interruptions in the supply of natural resources, political and governmental changes, disruption in transportation networks or delivery services, severe weather conditions, wildfires and other fires, explosions, actions of animal rights activists, terrorist attacks, earthquakes, wars, and public health issues (including the COVID-19 pandemic) could disrupt our operations or those of our collaborators, contractors, and vendors or contribute to unfavorable economic or other conditions that could adversely impact us.

In addition, we depend on the efficient and uninterrupted operation of our computer and communications systems, which we use for, among other things, sensitive company data, including our financial data, intellectual property, and other proprietary business information.

While certain of our operations have business continuity and disaster recovery plans and other security measures intended to prevent and minimize the impact of IT-related interruptions, our IT infrastructure and the IT infrastructure of our current and any future collaborators, contractors, and vendors are vulnerable to damage from cyberattacks, computer viruses, unauthorized access, electrical failures and natural disasters or other catastrophic events. We could experience failures in our information systems and computer servers, which could result in an interruption of our normal business operations and require substantial expenditure of financial and administrative resources to remedy. System failures, accidents, or security breaches can cause interruptions in our operations and can result in a material disruption of our research and development programs and other business operations. The loss of data from completed or future studies or clinical trials could result in delays in our research, development, or regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Similarly, we and our licensees rely on third parties to conduct studies and clinical trials of our drug candidates and manufacture our drug candidates, and similar events relating to these third parties’ computer systems could also have a material adverse effect on our business. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liabilities and the development of any of our other drug candidates and the commercialization of drugs could be delayed or otherwise adversely affected.

Even though we believe we carry commercially reasonable business interruption and liability insurance, and our contractors may carry liability insurance that protect us in certain events, we might suffer losses as a result of business interruptions that exceed the coverage available under our and our contractors’ insurance policies or for which we or our contractors do not have coverage. For example, we are not insured against a terrorist attack. Any natural disaster or catastrophic event could have a significant negative impact on our operations and financial results. Moreover, any such event could delay our research and development programs and adversely affect, which may include stopping, our commercial production.

We and our employees and directors may be named as defendants in litigation that could result in substantial costs and divert management’s attention.

Securities class action litigation may be brought against a company following a decline in the market price of its securities. This risk is especially relevant for us because companies in the pharmaceuticals industry often experience significant stock price volatility. For example, beginning in 2010, a number of lawsuits were filed against us and certain of our employees and directors alleging we and the other defendants violated federal securities laws by making materially false and misleading statements regarding our lorcaserin trials, thereby artificially inflating the price of our common stock. These lawsuits were settled in 2018.

While we carry liability insurance, any losses we incur in connection with any current or future lawsuits may not be covered by insurance in an amount sufficient to cover our losses or at all, and our assets may be insufficient to cover any amounts that exceed our insurance coverage. We may have to pay damage awards or otherwise may enter into settlement arrangements in connection with any future claims. A settlement of any of future lawsuit against us could also involve the issuance of common stock or other equity, which may dilute your ownership interest. Any payments or settlement arrangements could have material adverse effects on our business, operating results, financial condition, or your ownership interest. Even if the plaintiffs’ claims are not successful, any future lawsuit against us and/or our directors or executive officers could result in substantial costs and significantly and adversely impact our reputation and divert our management’s attention and resources, which could have a material adverse effect on our business, operating results or financial condition. In addition, any such lawsuits may make it more difficult to finance our operations, obtain certain types of insurance (including directors’ and officers’ liability insurance), and attract and retain qualified executive officers, other employees, and directors.

42


 

Negative U.S. and global economic conditions may pose challenges to our business strategy, which relies on funding from collaborators or the financial markets, and may create other financial risks for us.

While significant uncertainty remains as to the aggregate impact of the COVID-19 pandemic on our operations and liquidity, and on the global economy as a whole, the COVID-19 pandemic has already had a significant adverse impact on domestic and global economies, as well as global financial markets. Negative conditions in the U.S. or global economy, including financial markets, may adversely affect our business and the business of our current and prospective collaborators, distributors, and licensees, which we sometimes refer to generally as our collaborators, and others with which we do or may conduct business. The duration and severity of these conditions is uncertain. If negative economic conditions persist or worsen, we may be unable to secure funding to sustain our operations or to find suitable collaborators to advance our internal programs, even if we achieve positive results from our research and development or business development efforts. Such negative conditions could also impact commercialization of any drugs we and our collaborators and licensees develop, as well as our financial condition. From time to time we may maintain a portfolio of investments in marketable debt securities, which are recorded at fair value. Although we have established investment guidelines relative to diversification and maturity with the objectives of maintaining safety of principal and liquidity, we rely on credit rating agencies to help evaluate the riskiness of investments, and such agencies may not accurately predict such risk. In addition, such agencies may reduce the credit quality of our individual holdings, which could adversely affect their value. Lower credit quality and other market events, such as changes in interest rates and deterioration in credit markets, may have an adverse effect on the fair value of our investment holdings and cash position.

Currency fluctuations may negatively affect our financial condition.

We primarily spend and generate cash in U.S. dollars and present our consolidated financial statements in U.S. dollars. However, a portion of our expected and potential payments and receipts, including relating to our Swiss operations and under certain of our agreements, are in foreign currencies. A fluctuation of the exchange rates of foreign currencies versus the U.S. dollar may, thus, adversely affect our financial results, including cash balances, expenses and revenues. We may in the future enter into hedging transactions to try to reduce our foreign currency exposure, but there is no assurance that such transactions will occur or be successful.

Our ability to use net operating losses and certain other tax attributes to offset future taxable income or taxes may be limited.

As of December 31, 2020, we had federal and state net operating loss carryforwards of $945.7 million and $446.6 million, respectively. Portions of our federal net operating loss carryforwards will begin to expire, if not utilized, beginning in 2028, and our state net operating loss carryforwards of $446.6 million begin expiring in 2028. Our net operating loss carryforwards could expire unused and be unavailable to offset future income tax liabilities. Under the TCJA, as modified by the Coronavirus Aid, Relief, and Economic Security Act, or CARES Act, federal net operating losses incurred in tax years beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such federal net operating losses in tax years beginning after December 31, 2020 is limited to 80% of taxable income. It is uncertain if and to what extent various states will conform to federal tax laws. In addition, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, or the IRC, and corresponding provisions of state law, if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change, by value, in its equity ownership over a three-year period, the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income or taxes may be limited. We have experienced ownership changes in the past and we may experience additional ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which may be outside of our control. If an ownership change occurs and our ability to use our net operating loss carryforwards is materially limited, it would harm our future operating results by effectively increasing our future tax obligations. Similar provisions of state law may also apply to limit the use of our state net operating loss carryforwards.  In addition, at the state level, there may be periods during which the use of net operating losses is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed.  For example, California passed legislation imposing limits on the usability of California state net operating losses and certain tax credits in tax years beginning after 2019 and before 2023.

Risks Relating to Our Intellectual Property

Our success is dependent on intellectual property rights held by us and third parties and our interest in these rights is complex and uncertain.

Our success will depend on our own and on current or future collaborators’ abilities to obtain, maintain, and defend patents. In particular, the patents directed to our drug candidates and drugs are important to developing and commercializing drugs and to our revenue. We have numerous U.S. and foreign patents issued and patent applications pending for our technologies. There is no assurance that any of our patent applications will issue, or that any of the patents will be enforceable or will cover a drug or other commercially significant technology or method, or that the patents will be held to be valid for their expected terms.

43


 

The procedures for obtaining a patent are complex. These procedures require an analysis of the scientific technology related to the invention and many sophisticated legal issues. Obtaining patent rights outside the United States often requires the translation of highly technical documents and an improper translation may jeopardize our patent protection. Ensuring adequate quality of translators and foreign patent attorneys is often very challenging. Consequently, the process for having our pending patent applications issue as patents will be difficult, complex, time consuming, and expensive. Our patent position is very uncertain, and we do not know when, or if, we will obtain additional patents, or if the scope of the patents obtained will be sufficient to protect our drugs or be considered sufficient by parties reviewing our patent positions pursuant to a potential marketing, licensing, or financing transaction.

In addition, other entities may challenge the validity or enforceability of our patents in litigation or administrative proceedings. We cannot make assurances as to how much protection, if any, our patents will provide if we attempt to enforce them or if they are challenged. It is possible that a competitor or a generic pharmaceutical provider may successfully challenge our patents and those challenges may result in reduction or elimination of our patent coverage.

We also rely on confidentiality agreements and trade secrets to protect our technologies. However, such information is difficult to protect. We require our employees to contractually agree not to improperly use our confidential information or disclose it to others, but we may be unable to determine if our employees have conformed or will conform to their legal obligations under these agreements. We also enter into confidentiality agreements with prospective collaborators, collaborators, service providers, and consultants, but we may not be able to adequately protect our trade secrets or other proprietary information in the event of any unauthorized use or disclosure or the lawful development by others of this information. Many of our employees and consultants were, and many of them may currently be, parties to confidentiality agreements with other pharmaceutical and biotechnology companies, and the use of our technologies could violate these agreements. In addition, third parties may independently discover our trade secrets or other proprietary information.

Some of our research and development collaborators and scientific consultants have rights to publish data and information to which we have rights. We generally seek to prevent our collaborators and consultants from disclosing scientific discoveries before we have the opportunity to file patent applications on such discoveries. In some of our collaborations we do not control our collaborators’ ability to disclose their own discoveries under the collaboration, and in some of our academic relationships we are limited to relatively short periods to review a proposed publication and file a patent application. If we cannot maintain confidentiality in connection with our collaborations and relationships, our ability to receive patent protection or protect our proprietary information will be impaired.

We believe that the United States is by far the largest single market for pharmaceuticals in the world. Because of the critical nature of patent rights to our industry, changes in U.S. patent laws could have a profound effect on our future profits, if any. It is unknown which, if any, patent laws will change, how changes to patent laws would ultimately be enforced by the courts, and how they would impact our business.

A dispute regarding the infringement or misappropriation of our proprietary rights or the proprietary rights of others could be costly and result in delays or termination of our future research, development, manufacturing, and sales activities.

Our commercial success depends upon our ability to develop and manufacture our drugs and drug candidates, market and sell drugs, and conduct our research and development activities without infringing or misappropriating the proprietary rights of others. There are many issued patents and pending patent applications owned by others relating to research and development programs that could be determined to be similar, identical, or superior to ours or our licensors or collaborators. We may be exposed to future litigation by others based on claims that our drugs, drug candidates, technologies, or activities infringe the intellectual property rights of others. Numerous issued patents and pending patent applications owned by others exist in the areas of our research and development, including some that purport to allow the patent holder to control the use of all drugs that modulate a particular drug target regardless of whether the infringing drug bears any structural resemblance to a chemical compound known to the patent holder at the time of patent filing. Numerous issued patents and pending patent applications owned by others also exist in the therapeutic areas in which we are developing drugs. There are also numerous issued patents and pending patent applications owned by others that are directed to chemical compounds or synthetic processes that may be necessary or useful to our research, development, manufacturing, or commercialization activities. These could materially affect our ability to develop our drug candidates or manufacture, import, or sell drugs, and our activities, or those of our licensors or collaborators, could be determined to infringe these patents. Because patent applications can take many years to issue, there may be currently pending applications, unknown to us, that may later result in issued patents that our drugs, drug candidates, or technologies may infringe. There also may be existing patents owned by others, of which we are not aware, that our drug candidates or technologies may infringe. Further, there may be issued patents or pending patent applications owned by others in fields relevant to our business, of which we are or may become aware, that we believe (i) are invalid, unenforceable, or we do not infringe; (ii) relate to immaterial portions of our overall research and development, manufacturing, and commercialization efforts; or (iii) in the case of pending patent applications, the resulting patent would not be granted or, if granted, would not likely be enforced in a manner that would materially impact such efforts. We cannot assure you that others holding any of these patents or patent applications will not assert infringement claims against us and seek

44


 

damages or enjoinment of our activities. We also cannot assure you that, in the event of litigation, we will be able to successfully assert non-infringement, unenforceability, invalidity, or immateriality, or that any infringement claims will be resolved in our favor.

In addition, others may infringe or misappropriate our proprietary rights. We may have to institute costly legal action to protect our intellectual property rights, or we may not be able to afford the costs of enforcing or defending our intellectual property rights.

There could be significant litigation and other administrative proceedings in our industry that affect us regarding patent and other intellectual property rights. Any legal action or administrative action against us, or our collaborators, claiming damages or seeking to enjoin commercial activities relating to our research and development, manufacturing, and commercialization activities could:

 

require us, or our collaborators, to obtain a license which may not be available on commercially reasonable terms, if at all;

 

prevent us from importing, making, using, selling, or offering to sell the subject matter claimed in patents held by others and subject us to potential liability for damages;

 

consume a substantial portion of our managerial, scientific, and financial resources; or

 

be costly, regardless of the outcome.

Furthermore, because of the substantial amount of pre-trial document and witness discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised. In addition, during the course of intellectual property litigation, there could be public announcements of the results of hearings, motions, or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the trading price of our common stock.

We are aware of third-party patents, as well as third-party patent applications, that could adversely affect the potential commercialization of etrasimod. For example, we are aware of third-party patents, as well as a third-party patent application, with broad claims to administering an S1P modulator by starting with a lower dose and then increasing to a higher, standard daily dose. While we do not believe that any such claims that would cover the potential commercialization of etrasimod are valid and enforceable, we may be incorrect in this belief.

We have been contacted from time to time by third parties regarding their intellectual property rights, sometimes asserting that we may need a license to use their technologies. If we fail to obtain any required licenses or make any necessary changes to our technologies, we may become involved in expensive and time-consuming litigation or we may be unable to develop or commercialize some or all of our drugs or drug candidates.

We cannot predict the outcome of any litigation matter. For example, our existing patents could be invalidated, found unenforceable or found not to cover a generic form of our drugs.

We cannot protect our intellectual property rights throughout the world.

Filing, prosecuting, defending, and enforcing patents on all of our drug candidates throughout the world would be prohibitively expensive. The laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the United States, and many companies have encountered significant problems in protecting and defending such rights in foreign jurisdictions. Many countries, including certain countries in Europe, have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties (for example, the patent owner has failed to “work” the invention in that country or the third party has patented improvements). In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of the patent. Compulsory licensing of life-saving drugs is also becoming increasingly popular in developing countries either through direct legislation or international initiatives. Such compulsory licenses could be extended to include some of our drug candidates, which could limit our potential revenue opportunities. Moreover, the legal systems of certain countries, particularly certain developing countries, do not favor the aggressive enforcement of patents and other intellectual property protection, particularly those relating to pharmaceuticals, which makes it difficult for us to stop the infringement of our patents. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial cost and divert our efforts and attention from other aspects of our business.

Risks Relating to Our Securities

Our stock price will likely be volatile, and your investment in our stock could decline in value.

Our stock price has fluctuated historically. From January 1, 2020, to February 18, 2021, the market price of our stock was as low as $32.95 per share and as high as $90.19 per share. The stock market, particularly in recent years, has experienced significant

45


 

volatility particularly with respect to pharmaceutical and biotechnology stocks, and this trend may continue. The ongoing COVID-19 pandemic, for example, has previously negatively affected the stock market and investor sentiment and has resulted in significant volatility, and the COVID-19 pandemic may have these effects in the future.

Very few drug candidates being tested will ultimately receive regulatory approval, and companies in our industry sometimes experience significant volatility in their stock price. Our stock price may fluctuate significantly depending on a variety of factors, including:

 

results or decisions affecting the development or commercialization of any of our drug candidates or drugs, including the results of studies, trials and other analyses;

 

the success, failure or setbacks of our or a perceived competitor’s drugs or drug candidates;

 

the timing of the development of our drug candidates;

 

discussions or recommendations affecting our drugs or drug candidates by the FDA or other reviewers of preclinical or clinical data or other information related to our drug candidates or drugs;

 

regulatory actions or decisions or legislation affecting drugs or drug candidates, including ours and those of our competitors;

 

the commercial availability and success or failure of any of our drug candidates;

 

the development and implementation of our continuing development and research plans;

 

the entrance into, or failure to enter into, a new collaboration or the modification or termination of an existing collaboration or other material transaction;

 

the timing and receipt by us of milestone and other payments or failing to achieve and receive the same;

 

fluctuation in prescriptions, sales, or financial results (including with respect to revenue recognition, expenses, and other operating results) or inaccurate sales or cash forecasting;

 

accounting restatements and changes;

 

supply chain or manufacturing issues;

 

changes in our research and development budget or the research and development budgets of our existing or potential collaborators;

 

the introduction, development or withdrawal of drug candidates or drugs by others that target the same diseases and conditions that we or our collaborators target or the introduction of new drug discovery techniques;

 

expenses related to, and the results of, litigation, other disputes and other proceedings;

 

financing strategy or decisions;

 

the allocation of our resources;

 

our ability, or the perception by investors of our ability, to continue to meet all applicable requirements for continued listing of our common stock on The Nasdaq Stock Market, and the possible delisting of our common stock if we are unable to do so;

 

developments in intellectual property rights or related announcements;

 

disruptions caused by man-made or natural disasters or public health pandemics or epidemics or other business interruptions, including, for example, the COVID-19 pandemic; and

 

capital market and other macroeconomic conditions.

We are not able to control many of these factors. If our financial or scientific results in a particular period do not meet stockholders’ or analysts’ expectations, our stock price may decline, and such decline could be significant.

Any future equity or debt issuances or other financing transactions may have dilutive or adverse effects on our existing stockholders.

We have been opportunistic in our efforts to obtain cash, and we expect we will evaluate various funding alternatives from time to time. We may issue additional shares of common stock or convertible securities that could dilute your ownership in our company and may include terms that give new investors rights that are superior to yours. We have effective registration statements to sell shares of our common stock and certain other securities, and we may elect to sell shares pursuant to such registration from time to time. In

46


 

February 2020, we entered into a sales agreement with Credit Suisse Securities (USA) LLC, SVB Leerink LLC and Cantor Fitzgerald & Co., pursuant to which we may sell and issue shares of our common stock having an aggregate offering price of up to $250.0 million from time to time in transactions that are deemed to be “at-the-market offering” as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended, or Securities Act. As of the date of this report we have sold 1.2 million shares for aggregate gross proceeds of $100.6 million under the sales agreement and may sell and issue approximately $149.4 million in additional shares under the sales agreement.

Moreover, any issuances by us of equity securities may be at or below the prevailing market price of our common stock and in any event may have a dilutive impact on your ownership interest, which could cause the market price of our common stock to decline. In addition, we may also raise additional funds through the incurrence of debt or other financing transaction, and the investors may have rights superior to your rights in the event we are not successful and are forced to seek the protection of bankruptcy laws or the transaction may otherwise adversely affect our business prospects and existing stockholders.

There are a substantial number of shares of our common stock that may become eligible for future sale in the public market, and the sale of our common stock could cause the market price of our common stock to fall.

As of February 18, 2021, there were (i) options to purchase 8,344,308 shares of our common stock outstanding under our equity incentive plans at a weighted-average exercise price of $41.02 per share, (ii) 242,563 restricted stock unit awards outstanding under our equity incentive plans, (iii) performance restricted stock units outstanding under our equity incentive plans under which up to 25,200 shares of common stock may be issuable upon achievement of all specified performance goals, (iv) 2,465,387 additional shares of common stock remaining issuable under our Amended and Restated 2020 Long-Term Incentive Plan, and (v) 935,544 shares issuable under our 2019 Employee Stock Purchase Plan.

Once issued, the shares described above will be available for immediate resale in the public market. The market price of our common stock could decline as a result of such resales due to the increased number of shares available for sale in the market. As of February 18, 2021, there were 60,334,648 shares of our common stock outstanding.

Our executive officers and directors, and other holders of our common stock and other securities, may take actions that are contrary to your interests, including selling their stock.

Sales of our stock by our executive officers and directors, or the perception that such sales may occur, could adversely affect the market price of our stock. Our executive officers and directors may sell stock in the future, either as part, or outside, of trading plans under Rule 10b5-1 of the SEC.

A small number of stockholders may hold or acquire a significant amount of our outstanding stock. From time to time, there is a large short interest in our stock. These holders of such stock or positions may seek control of us, may support transactions that we or you do not believe are favorable, and may have interests that are different from yours. In addition, sales of a large number of shares of our stock by these large stockholders or other stockholders within a short period of time could adversely affect our stock price.

We may also be involved in disagreements with the holders of our stock, warrants, or other securities in the future. Such disagreements may lead to proxy contests or litigation, which may be expensive and consume management’s time, involve settlements, the terms of which may not be favorable to us, or result in other negative consequences to our business.

Certain of our agreements, provisions in our charter documents, possible future agreements and Delaware law could delay or prevent a change in management or a takeover attempt that you may consider to be in your best interests.

There is a standstill provision in our transaction agreement with Eisai, and we may enter into agreements with others that contain similar provisions. In addition, we may in the future adopt a stockholders’ rights agreement, which would cause substantial dilution to any person who attempts to acquire us in a manner or on terms not approved by our board of directors. These provisions or agreements, as well as other provisions in our certificate of incorporation and bylaws and under Delaware law, could delay or prevent the removal of directors and management and could make more difficult a merger, tender offer, or proxy contest involving us that you may consider to be in your best interests. For example, our charter provisions:

 

allow our board of directors to issue preferred stock without stockholder approval;

 

limit who can call a special meeting of stockholders;

47


 

 

 

eliminate stockholder action by written consent; and

 

establish advance notice requirements for nomination for election to the board of directors or for proposing matters to be acted upon at stockholders’ meetings.

Our bylaws provide that the Court of Chancery of the State of Delaware and the federal district courts of the United States of America are the exclusive forums for substantially all 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 bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for (a) any derivative action or proceeding brought on behalf of us, (b) any action asserting a claim of breach of a fiduciary duty owed by any of our directors or any of our officers or other employees to us or our stockholders, (c) any action asserting a claim against us or any of our directors or any of our officers or other employees arising pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws, or (d) any action asserting a claim against us or any of our directors or any of our officers or other employee governed by the internal affairs doctrine. This provision does not apply to suits brought to enforce a duty or liability created by the Securities Act or the Exchange Act. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all such Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, our bylaws further provides that, unless we consent in writing to the selection of an alternative forum, 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 arising under the Securities Act. 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. In such instance, we would expect to vigorously assert the validity and enforceability of the exclusive forum provisions of our bylaws. This may require significant additional costs associated with resolving such action in other jurisdictions and there can be no assurance that the provisions will be enforced by a court in those other jurisdictions.

These exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers and other employees. If a court were to find either exclusive forum provision in our bylaws to be inapplicable or unenforceable in an action, we may incur further significant additional costs associated with resolving the dispute in other jurisdictions, all of which could seriously harm our business.

General Risk Factors

Laws, rules, and regulations, including relating to public companies, may be costly and impact our ability to attract and retain directors and executive officers.

Laws and regulations affecting public companies, including rules adopted by the SEC and by Nasdaq, judicial rulings, and other laws and regulations, including, for example, of state, federal, and foreign governments and relating to privacy, may result in increased costs to us, particularly as we continue to develop the required capabilities in the United States and abroad to develop and commercialize our product candidates. These laws, rules, and regulations could make it more difficult or costly for us to obtain certain types of insurance, including directors’ and officers’ liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. These laws, rules, and regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, on our board committees, or as executive officers. We cannot estimate accurately the amount or timing of additional costs we may incur to respond to these laws, rules, and regulations.

Changes in funding for the FDA, the SEC, and other government agencies could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner, or otherwise prevent those agencies from performing normal functions on which the operation of our business may rely, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept payment of user fees, 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 the SEC and other government agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical

48


 

FDA, SEC, and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, future government shutdowns could impact our ability to access the public markets and obtain capital necessary to properly capitalize and continue our operations.

The withdrawal of the United Kingdom from the European Union, commonly referred to as “Brexit,” may adversely impact our ability to obtain regulatory approvals of our product candidates in the European Union, result in restrictions or imposition of taxes and duties for importing our product candidates into the European Union, and may require us to incur additional expenses in order to develop, manufacture and commercialize our product candidates in the European Union.

Following the result of a referendum in 2016, the United Kingdom left the European Union on January 31, 2020, commonly referred to as “Brexit.” Pursuant to the formal withdrawal arrangements agreed between the United Kingdom and the European Union, the United Kingdom was subject to a transition period that ended December 31, 2020, or the Transition Period, during which EU rules continued to apply. A trade and cooperation agreement, or the Trade and Cooperation Agreement, that outlines the future trading relationship between the United Kingdom and the European Union was agreed in December 2020.

Since a significant proportion of the regulatory framework in the United Kingdom applicable to our business and our product candidates is derived from EU directives and regulations, Brexit has had, and may continue to have, a material impact on the regulatory regime with respect to the development, manufacture, importation, approval and commercialization of our product candidates in the United Kingdom or the European Union. For example, Great Britain is no longer covered by the centralized procedures for obtaining EU-wide marketing authorization from the EMA and, and a separate marketing authorization will be required to marker our product candidates in Great Britain. It is currently unclear whether the Medicines & Healthcare products Regulatory Agency, or MHRA, in the U.K. is sufficiently prepared to handle the increased volume of marketing authorization applications that it is likely to receive.

While the Trade and Cooperation Agreement provides for the tariff-free trade of medicinal products between the UK and the EU there may be additional non-tariff costs to such trade which did not exist prior to the end of the Transition Period.  Further, should the UK diverge from the EU from a regulatory perspective in relation to medicinal products, tariffs could be put into place in the future.  We could therefore, both now and in the future, face significant additional expenses (when compared to the position prior to the end of the Transition Period) to operate our business, which could significantly and materially harm or delay our ability to generate revenues or achieve profitability of our business. Any further changes in international trade, tariff and import/export regulations as a result of Brexit or otherwise may impose unexpected duty costs or other non-tariff barriers on us. These developments, or the perception that any of them could occur, may significantly reduce global trade and, in particular, trade between the impacted nations and the UK It is also possible that Brexit may negatively affect our ability to attract and retain employees, particularly those from the EU. These developments, or the perception that any of them could occur, may significantly reduce global trade and, in particular, trade between the impacted nations and the United Kingdom.

Our employees, clinical trial investigators, CROs, CMOs, consultants, vendors, and collaborators 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, clinical trial investigators, CROs, CMOs, consultants, vendors, and collaborators. Misconduct by these parties could include intentional, reckless and/or negligent conduct or disclosure of unauthorized activities to us that violates:

 

FDA regulations or those of comparable foreign regulatory authorities, including those laws that require the reporting of true, complete and accurate information;

 

manufacturing standards;

 

federal and state health and data privacy, security, fraud and abuse, government price reporting, transparency reporting requirements, and other healthcare laws and regulations in the United States and abroad;

 

sexual harassment and other workplace misconduct; or

 

laws that require the true, complete and accurate reporting of financial information or data.

Such misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and cause serious harm to our reputation.

We have adopted a Code of Business Conduct and Ethics and other policies and procedures, but it is not always possible to identify and deter misconduct, 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 governmental investigations or other actions or lawsuits stemming

49


 

from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant civil, criminal, and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from government funded healthcare programs, such as Medicare, Medicaid, and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, additional integrity reporting and oversight obligations, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

Our disclosure controls and procedures and our internal control over financial reporting may not prevent potential errors and fraud.

Our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all potential errors and fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. There are inherent limitations in all control systems, and no system of controls can provide absolute assurance that all control issues and instances of fraud, if any, or misstatements due to error, if any, within the company have been detected. While we believe that our disclosure controls and procedures and internal control over financial reporting are and have been effective at the reasonable assurance level, we intend to continue to examine and refine our disclosure controls and procedures and internal control over financial reporting and to monitor ongoing developments in these areas.

Current and future tax laws and regulation could adversely affect our business and financial condition.

New income, sales, use, or other tax laws, statutes, rules, regulations, or ordinances could be enacted at any time, which could affect the tax treatment of our domestic and foreign earnings. Any new taxes could adversely affect our domestic and international business operations, and our business and financial performance. Further, existing tax laws, statutes, rules, regulations, or ordinances could be interpreted, changed, modified, or applied adversely to us. For example, the TCJA significantly revised the IRC. Future guidance from the Internal Revenue Service and other tax authorities with respect to the TCJA may affect us, and certain aspects of the TCJA could be repealed or modified in future legislation. For example, the CARES Act modified certain provisions of the TCJA. In addition, it is uncertain if and to what extent various states will conform to the TCJA, the CARES Act, or any newly enacted federal tax legislation. Changes in corporate tax rates, the realization of net deferred tax assets relating to our operations, the taxation of foreign earnings, and the deductibility of expenses under the TCJA or future reform legislation could have a material impact on the value of our deferred tax assets, could result in significant one-time charges, and could increase our future U.S. tax expense.

We have an international corporate structure and intercompany arrangements that includes licensing of worldwide intellectual property rights related to certain of our drug candidates to one or more wholly owned subsidiaries in order to, among other things, build a platform for long-term operational and financial efficiencies. One such efficiency is the potential reduction of our worldwide effective tax rate on certain potential future revenues. The application of the tax laws of the jurisdictions in which we operate our international business activities is subject to interpretation and depends on our ability to operate our business in a manner consistent with our corporate structure and intercompany arrangements. Future changes in U.S. and non-U.S. tax laws, including implementation of international tax reform relating to the tax treatment of multinational corporations, if enacted, may reduce or eliminate any potential financial efficiencies that we hoped to achieve by establishing this operational structure. Additionally, taxing authorities, such as the U.S. Internal Revenue Service, may audit and otherwise challenge these types of arrangements, and have done so with other companies in the pharmaceutical industry. If any such changes in tax law are enacted, or our international corporate structure and intercompany arrangements are otherwise challenged, our business could be materially adversely impacted.

Changes or modifications in financial accounting standards, including those related to revenue recognition, may harm our results of operations.

From time to time the Financial Accounting Standards Board, or FASB, either alone or jointly with other organizations, promulgates new accounting principles that could have an adverse impact on our financial position, results of operations, or reported cash flows. Any difficulties in adopting or implementing any new accounting standard, or updating or modifying our internal controls as needed on a timely basis, could result in our failure to meet our financial reporting obligations, which could result in regulatory discipline and harm investors’ confidence in us. In addition, if we were to change our critical accounting estimates, including those related to the recognition of revenue, our operating results could be significantly affected.

Market information

Our common stock is listed on the Nasdaq Global Select Market under the symbol “ARNA.”

Holders

As of February 18, 2021, there were approximately 81 stockholders of record of our common stock, one of which is Cede & Co., a nominee for Depository Trust Company, or DTC. Shares of common stock that are held by financial institutions as nominees for beneficial owners are deposited into participant accounts at DTC and are considered to be held of record by Cede & Co. as one stockholder.

Dividends

We have never paid cash dividends on our capital stock. We anticipate that we will retain earnings, if any, to support operations and finance the growth and development of our business and, therefore, do not expect to pay cash dividends in the foreseeable future.

Performance graph

The graph below compares the cumulative five-year total return on our common stock from December 31, 2015, through December 31, 2020, to the cumulative total return over such period for (i) the Nasdaq Composite Index and (ii) the Nasdaq Biotechnology Index.
