ITEM 1. BUSINESS 

Overview 

We are a biotechnology company devoted to discovering and developing innovative therapies designed to treat immune-mediated diseases. Our lead 

product candidate, reproxalap, is a first-in-class treatment in late-stage development for dry eye disease (DED) and allergic conjunctivitis (AC). We have 
additional product candidates in development for autoimmune diseases and other immune-mediated disease, as well as for proliferative vitreoretinopathy 
(PVR) and other retinal diseases. We currently intend to commercialize our products directly or through collaborations. None of our product candidates 
have been approved for sale in the United States or elsewhere.

Immune-mediated diseases are conditions that result from an imbalance of inhibitory and stimulatory factors that regulate the immune system. 

Immunological dysregulation can lead to a broad array of conditions that include autoimmune disease, allergy, immunoproliferative disease, and cancer. 
Many ocular, cardiovascular, metabolic, neurological, and musculoskeletal diseases, affecting tens of millions of patients in the United States and hundreds 
of millions of patients worldwide, are at least partially immune-mediated. An estimated 7% of western society suffers from some form of immune-
mediated disease, and incidence has been increasing. Given the complexity of immune dysregulation, which involves many mediators and signaling 
pathways, rarely is any single therapeutic approach effective, and today most immune-mediated diseases are generally considered to be inadequately 
treated. As such, we believe immune-mediated diseases represent considerable unmet medical need, and that demand for novel immune-modulating 
therapies is high. Consistent with large patient populations and high therapeutic demand, the current market for the treatment of immune-mediated diseases 
is considerable, representing an excess of $40 billion worldwide.

Our clinical product development pipeline is focused on immune-mediated ocular diseases and select systemic diseases, and encompasses two 
distinct biological mechanisms of action: reactive aldehyde species (RASP) modulation and dihydrofolate reductase inhibition. The immunological activity 
of our product candidates generally leads to diminished levels of pathological inflammation via down-regulation of immune cell activation or proliferation.

Our lead product candidate reproxalap is a RASP modulator that has been shown to diminish ocular inflammation, and has demonstrated statistically 

significant and clinically relevant improvements across a number of Phase 2 and Phase 3 clinical trials in DED and AC when administered topically to the 
eye as an ophthalmic solution. Additionally, in a Phase 1 clinical trial, ADX-629, a first-in-class orally available RASP modulator, was well-tolerated and 
no treatment-related adverse events were observed. Relative to subjects treated with placebo, reduction in the commonly described pro-inflammatory RASP 
malondialdehyde was observed in ADX-629 treated subjects. A growing body of clinical evidence supports the potential and relevance of RASP 
modulation as a new and differentiated mechanism of action. We have discovered and are developing additional RASP modulators. The RASP modulator 
platform represents a unique and novel pharmacologic approach that, unlike almost all drugs in use today, are designed to not directly inhibit or activate a 
particular protein but instead targets a family of small molecules that in turn affect the activity and structure of many proteins at once. RASP modulation, 
therefore, has the 

5

 
potential to down-regulate pro-inflammatory systems or groups of proteins, and may lead to multiple beneficial clinical effects while avoiding toxicity 
associated with single-target inhibition or activation.

As we continue to execute on our strategy of expanding our product candidate pipeline, we may license or acquire new immune-modulating 
approaches with novel therapeutic potential. In January 2019, we acquired Helio Vision, Inc. and thereby obtained rights to ADX-2191, a vitreous-
compatible methotrexate formulation for intraocular injection, for the prevention of PVR, a serious sight-threatening retinal disease with no approved 
treatment, and primary vitreoretinal lymphoma (PVRL), a rare cancer with no approved treatment. In addition, in December 2016, we in-licensed the 
clinical-stage product candidate ADX-1612 (investigated in oncology under the name ganetespib), which inhibits the protein chaperome, a mechanistically 
differentiated approach for the potential treatment of inflammatory diseases. 

Our active clinical programs include three unique product candidates, representing two distinct mechanisms of action across a number of different 

potential indications. All of our development plans and timelines are subject to adjustment depending on recruitment rate, regulatory review, preclinical and 
clinical results, funding, and other factors that could delay the initiation, completion, or reporting of clinical trials. As a result of the COVID-19 pandemic, 
clinical site availability, staffing, patient recruitment, and patient retention have been negatively affected and the timelines to complete our clinical trials 
may be delayed. Our pipeline, as of the date of filing this annual report on Form 10-K is illustrated below.

Product Candidate Development Pipeline

1Timing depends, in part, on restrictions related to the COVID-19 pandemic, the availability of clinical research facilities and staffing, the ability to recruit patients, and regulatory feedback.
2New Drug Application, or NDA submission requirements depend, in part, on clinical results and regulatory feedback.

We have no products approved for sale. We will not receive any revenue from any product candidates that we develop until we obtain regulatory 
approval and commercialize such products or until we potentially enter into agreements with third parties for the development and commercialization of 
product candidates. If our development efforts for any of our product candidates result in regulatory approval or we enter into collaboration agreements 
with third parties, we may generate revenue from product sales or from such third parties. We have primarily funded our operations through the sale of our 
common stock, convertible preferred stock, convertible promissory notes, warrants, and borrowings under debt facilities.

6

 
 
 
We will need to raise additional capital in the form of debt or equity or through partnerships to fund additional development of our product 

candidates, and we may in-license, acquire, or invest in complementary businesses or products. In addition, contingent on capital resources, we may 
augment, diminish, or otherwise modify the clinical development plan described herein.

Since our incorporation, we have devoted substantially all of our resources to the preclinical and clinical development of our product candidates. 

Our ability to generate revenues, if any, largely depends upon our ability, alone or with others, to complete development of and obtain regulatory approvals 
for our product candidates, and to successfully manufacture, market, and sell our product candidates. The results of our operations will vary significantly 
from year-to-year and quarter-to-quarter, and depend on a number of factors, including risks related to our business and industry, risks relating to 
intellectual property and other legal matters, risks related to our common stock, and other risks that are detailed in the section of this annual report on Form 
10-K entitled “Risk Factors". 

The Markets for Our Product Candidates 

Dry Eye Disease and Allergic Conjunctivitis – Two Prevalent Diseases with Significant Comorbidity

The symptoms of DED - ocular pain, dryness, gritty sensation - and AC - ocular itching and tearing- are chronic and persistently disturbing, 

impacting quality of life and leading to loss of work and substantial economic burden. DED and AC are two of the most common diseases treated by 
ophthalmologists and optometrists, and physicians and patients regard therapy as inadequate in a substantial number of cases. 

There are approximately 18 million DED patients diagnosed in the United States, but only three topical ocular drugs are approved for DED 
treatment, cyclosporine (0.05% as Restasis®, 0.05% generic cyclosporine, or 0.09% as CequaTM), lifitegrast (5% as Xiidra®), and loteprednol (0.25% as 
Eysuvis®). The activity of cyclosporine and lifitegrast has been observed to be minimal or lacking in the majority of patients, and weeks or months of 
treatment may be required to achieve even modest clinical benefit with over 60% of patients discontinuing treatment within 12 months of initiation. 
Loteprednol, a generically available corticosteroid, is indicated only for short-term treatment (up to two weeks) due to corticosteroid-associated toxicity, 
which includes increases in intraocular pressure that may lead to glaucoma, the development of cataracts, ocular infection, and other ocular morbidities.

There are approximately 100 million patients in the United States with AC, and we estimate that up to 30 million of such AC patients do not respond 

adequately to, or are dissatisfied with, topical antihistamines, the current standard of care. A primary reason for dissatisfaction with antihistamines appears 
to be lack of durable activity, which may be due to the fact that histamine is only one of the biological mediators of the disease, and the fact that increased 
histamine levels persist for only 10 to 20 minutes following allergen exposure.

Many patients manifest symptoms of both DED and AC, and differential diagnosis can be challenging for physicians. Approximately half of dry eye 

patients complain of itching, which is generally considered the result of allergy, and approximately half of AC patients complain of dryness, which is 
generally considered the result of DED. There are currently no United States Food and Drug Administration (FDA)-approved products that are indicated to 
treat both DED and AC. Neither cyclosporine nor lifitegrast have been approved for use in patients with AC, and antihistamines are known to exacerbate 
ocular dryness. Thus, we believe that no currently available drug for DED or AC is likely to be effective for the chronic treatment of the substantial number 
of patients who experience symptoms of both diseases. 

By modulating RASP, which are elevated in a variety of inflammatory diseases, reproxalap represents a novel mechanism for diminishing ocular 

inflammation in DED and AC. In a number of Phase 2 and Phase 3 clinical trials in DED and AC reproxalap demonstrated consistent statistically 
significant and clinically relevant activity. We believe that reproxalap may have a commercially differentiated product profile versus currently approved 
drugs for each indication, having shown the potential for early and broad activity in DED, and durable activity in AC. 

Based on the late-stage clinical trial results to date, discussed below, we believe reproxalap could offer differentiated efficacy relative to existing 

DED medications, particularly with regard to early onset of action and breadth of activity. Thus, our current expectation is that reproxalap could be priced 
similarly to, or at a premium to, currently marketed drugs for DED, which are generally priced in the range of $480 to $650 per month. The potential 

7

 
size of the DED market is substantial. We estimate there to be 39 million patients with DED in the United States, of which approximately 18 million are 
diagnosed. Assuming approximately one-half of diagnosed patients are candidates for prescription medication, and assuming approximately four months of 
therapy per year, the potential total addressable market for reproxalap therapy in DED is greater than $23 billion in the United States. 

Contingent on the results of current and planned clinical trials in DED and AC, in addition to regulatory authority approval, we intend to 

commercialize reproxalap ophthalmic solution directly or through marketing partnerships. 

Proliferative Vitreoretinopathy, Primary Vitreoretinal Lymphoma, and Other Retinal Diseases 

PVR is a rare inflammatory disorder of the retina that leads to severe retinal scarring and blindness, and is the leading cause of failure of retinal 
reattachment surgery. Over 50% of PVR cases result in severe uncorrectable vision loss (visual acuity of 20/320 or worse), and 76% of PVR patients suffer 
from at least moderate uncorrectable vision loss. PVR occurs after up to 10% of surgeries for retinal detachment and 50% or more of surgeries for open 
globe injury. Based on the prevalence of primary retinal detachment, in addition to retinal detachment that occurs as a result of trauma, we estimate that 
there are, in aggregate, approximately 20,000 treatable cases of PVR in the United States, Europe, and Japan. By inhibiting cell growth and thereby 
diminishing scar formation, ADX-2191 has the potential to be the first FDA-approved drug for prevention of PVR. In April 2018, ADX-2191 received 
orphan drug designation from the FDA for the prevention of PVR and, in June 2020, ADX-2191 was designated an orphan medicinal product by the 
European Commission for the treatment of retinal detachment. In September 2019, ADX-2191 received fast track designation from the FDA for the 
prevention of PVR.

Primary vitreoretinal lymphoma (PVRL) is a rare, aggressive, high-grade cancer that arises in the vitreous and retina. An estimated 2,900 people in 

the United States suffer from PVRL, and approximately 600 new cases of PVRL are diagnosed in the United States per year. The median survival for 
newly diagnosed patients is less than five years. In January 2021, we received from the FDA preliminary written comments in preparation for a Pre-IND 
("Investigational New Drug”) Type B meeting regarding ADX-2191 for the treatment of PVRL. We believe the comments indicated that submission of a 
New Drug Application (NDA) for ADX-2191 for the treatment of PVRL may be possible without performing clinical trials. In the first quarter of 2021, we 
held a teleconference with the FDA to discuss the preliminary written comments and clarify the ADX-2191 NDA submission requirements for the 
treatment of PVRL. In July 2021, ADX-2191 received orphan drug designation from the FDA for the treatment of PVRL. ADX-2191 has the potential to 
be the first drug approved to treat PVRL.

In addition to PVR and PVRL, the retina is susceptible to a variety of immune-mediated diseases, many of which are mediated by RASP. 
Inflammatory retinal disorders that involve RASP include both posterior and pan-uveitis, uveitis-associated macular edema, diabetic macular edema, and 
diabetic retinopathy. Separately, RASP and RASP-adducts accumulate in dry age-related macular degeneration, Stargardt Disease (juvenile dry age-related 
macular degeneration-like disease), and Sjögren-Larsson Syndrome-associated maculopathy. We believe that the number of patients affected by immune-
mediated retinal disorders is considerable. In particular, during 2019 and 2020, the National Eye Institute estimated that diabetic retinopathy and age-
related macular degeneration affected approximately 10 million people in the United States, and was projected to double to 20 million individuals by 2050. 
The global ophthalmic therapeutics market was approximately $21 billion in 2021 with therapies for retinal disorders (age-related, macular degeneration 
and diabetic macular edema) exceeding $11 billion. Therefore, we believe that the total market potential of RASP modulators for the treatment of retinal 
disease is substantial. 

Immune-Mediated Systemic Diseases 

Immune-mediated systemic diseases, such as autoimmune disease, are generally chronic conditions characterized by excessive and misdirected 

inflammatory responses. In aggregate, autoimmune diseases and related systemic inflammatory disorders represent in excess of 23 million individuals in 
the United States and collectively, prescription drug sales are expected to exceed $74 billion by 2022. In 2021, the three top selling drugs for these 
autoimmune conditions accounted for approximately $28 billion in sales.

8

 
 
Given the complex pathophysiology of systemic immune-mediated disorders, many of which are caused by a variety of pro-inflammatory mediators, 

therapy often requires combinations of drugs with distinct mechanisms of action. As such, we believe novel product candidates for immune-mediated 
diseases are in high demand. 

Our RASP modulator platform represents a potential novel therapeutic approach for a variety of common systemic immune-mediated conditions. 
Because RASP appear to be involved in the generation and potentiation of inflammation in general, we believe the potential therapeutic applicability of 
RASP modulators is broad. We are not aware of any other company actively developing therapeutics that target RASP. In 2020, we announced the initiation 
of Phase 2 clinical trials of ADX-629, a first-in-class orally administered RASP modulator, for the treatment of COVID-19, atopic asthma, and psoriasis as 
part of a systematic strategy to assess activity across different types of immunological diseases. The Phase 2 clinical trials follow a successful Phase 1 
clinical trial of ADX-629, in which ADX-629 was well-tolerated, no treatment-related adverse events were observed, and target engagement was evidenced 
by statistically lower RASP levels in drug-treated subjects relative to controls.

The Competitive Landscape of Our Product Candidates 

The pharmaceutical industry is characterized by intense competition and rapid innovation. Our potential competitors include large pharmaceutical 

and biotechnology companies, specialty pharmaceutical companies, academic institutions, government agencies, and research institutions. We believe that 
the key competitive factors that will affect the development and potential commercial success of our product candidates are efficacy, safety, tolerability, and 
the ability to reduce the dependence on, or the dose of, other drug products. 

Many of our potential competitors have substantially greater financial, technical, and human resources than we do and significantly greater 
experience in the discovery and development of product candidates, obtaining FDA and other regulatory approvals of products, and the commercialization 
of those products. Accordingly, our competitors may be more successful than we may be in obtaining regulatory approval for products and achieving 
widespread market acceptance. Our competitors’ products may be more effective, or more effectively marketed and sold, than any product that we may 
commercialize, and may render our product candidates obsolete or non-competitive before we can recover the expenses of developing and commercializing 
any of our product candidates. Further, competitors with numerous approved products may be able to negotiate pricing and reimbursement that is more 
favorable than that which we may be able to achieve. We anticipate that we will face intense and increasing competition as new products enter the market 
and advanced technologies become available. In addition, the development of new treatment methods for the diseases we are targeting could render our 
products non-competitive or obsolete.

While our product candidates may manifest efficacy, tolerability, or safety advantages, many marketed therapies are generic or may be priced 

considerably lower than the pricing we anticipate for our product candidates. Pricing, in addition to healthcare plan coverage, prior authorization 
requirements, step edits, co-pay amounts, and related factors, may discourage the initial or prolonged use of our product candidates. Further, the recent 
growth of Pharmacy Benefit Managers has diminished the profitability of drug commercialization for smaller companies, and may hamper our ability to 
support our operations or compete effectively in the marketplace following regulatory approval, if any.

RASP Modulator Platform 

A number of academic groups have published on the concept of reducing RASP levels, primarily by using compounds with amines (certain 
nitrogen-containing molecules) that react with RASP through a chemical process known as the Schiff base reaction. Various RASP-binding amines have 
been described, particularly carnosine (a naturally occurring dipeptide), which has other potential mechanisms of action unrelated to RASP. At least one 
group has published on the use of certain nitrogen-containing marketed products to temporarily bind retinaldehyde (a RASP) as a potential therapy for 
retinal disease. Schiff base reactions have also been mentioned as possible explanations for a portion of the activity of aminoguanidine, pyridoxamine, and 
possibly other non-proprietary amine-containing compounds that have been tested in clinical trials for diabetic nephropathy. However, the Schiff base 
reaction is reversible, and generally the substrates (precursors) and products of the reaction exist in equilibrium such that, at any point in time, the RASP 
substrate may be bound or unbound. In this way, Schiff base reactions alone represent temporary RASP binding, and likely lead to the relocation of RASP 
rather than the elimination or long-term modulation of RASP. We believe that reproxalap and chemically related product candidates that we have 
discovered are differentiated from the above approaches in that the chemical structures of our product candidates are novel, and the reaction with RASP has 
been observed to be essentially irreversible in vivo, which, we believe, may result in a more effective means of modulating RASP levels. 

Other Immune-Modulating Pharmacotherapies 

A myriad of new treatments have been or are being developed to treat inflammatory diseases, and have been used, or in theory could be used, for the 
treatment of the diseases that our product candidates are intended to target. Immune-modulating products include cytokine inhibitors, immune cell receptor 
inhibitors, complement inhibitors, phosphodiesterase inhibitors, and Janus kinase inhibitors. Companies that currently market such therapies include 
Abbvie, Inc., Johnson & Johnson, UCB Inc. and UCB S.A., Amgen, Inc., Bristol-Myers Squibb Co., Eli Lilly and Company, Novartis AG, Regeneron 
Pharmaceuticals, Inc., Roche, Sanofi, Takeda, AstraZeneca, GlaxoSmithKline, Merck, and Pfizer, Inc. Currently marketed products may manifest efficacy 
and safety advantages over our product candidates, and may be used to treat the diseases for which we are developing our product candidates.

Methotrexate, the active drug substance of ADX-2191, is generically available and has been used as a chemotherapeutic and immune modulating 

agent, and other formulations or application methods of methotrexate could be developed for the treatment of retinal diseases. Though not approved by the 
FDA for the treatment of retinal disease, such as PVRL and PVR, intraocular injection of intravenous methotrexate formulations is the de facto standard of 
care, and “off-label” methotrexate is now commonly administered for the treatment of PVRL. The off-label intraocular injection of intravenous 
methotrexate for retinal diseases is an example of a practice known as compounding. The disadvantages of compounding are significant, and include  a risk 
of microbial contamination that can lead to severe ocular infection resulting in vision loss. Unlike compounded intravenous formulations, ADX-2191 is 
specifically formulated for intraocular injection such that drug concentration, density, pH, and tonicity have been designed to be compatible with the 
vitreous humor, the fluid in the back of the eye.

We believe that there is significant unmet medical need for the diseases that we intend to target. If proven to be safe and effective, we believe that 
our product candidates could be used in place of, or in addition to, current therapies. Currently available therapies for the treatment of DED are generally 
considered by physicians and patients to be inadequate, may require weeks or months of treatment to achieve even moderate clinical benefit, and have not 
demonstrated clinical activity in AC, a common comorbidity. There is no approved therapy for PVR or PVRL.

Many drugs are in development for AC and DED. In addition, generic versions of Restasis® became available in the U.S. in March 2022. We believe 

that there are currently no drugs in development for both DED and AC; PVR; or PVRL. For the diseases we intend to study, there may be other 
developmental therapies of which we are not aware.

Our ability to compete successfully will depend in part on our ability to utilize our drug development expertise to identify, develop, secure rights to, 

and obtain regulatory approvals for promising pharmaceutical products before others are able to develop competitive products. Our ability to compete 
successfully will also depend on our ability to attract and retain skilled and experienced personnel. Additionally, our ability to compete may be diminished 
by insurers and other third-party payors, which often encourage the use of cheaper, non-innovative, or generic products. 

Clinical Trial Results and Development Plans 

Prior to applying for marketing approval, our product candidates must satisfy regulatory authority requirements for safety and efficacy, including 

pivotal Phase 3 clinical assessment. Our active clinical programs with reproxalap have consistently demonstrated statistically and clinically significant 
efficacy, and have advanced to late-stage clinical testing. In addition, reproxalap has been observed to be well-tolerated and reported adverse events were 
generally mild in our clinical trials to date. Our material clinical results have been previously disclosed elsewhere in detail, and we encourage review of all 
of our clinical trial disclosures. All of our development plans and timelines are subject to adjustment depending on recruitment rate, regulatory review, 
preclinical and clinical results, funding, and other factors that could delay the initiation, completion, or reporting of clinical trials. As a result of the 
COVID-19 pandemic, clinical site availability, staffing, patient recruitment, and patient retention have been negatively affected and the timelines to 
complete our clinical trials may be delayed.

Dry Eye Disease

In September 2017, we announced that the results of a randomized, parallel-group, double-masked Phase 2a clinical trial of 0.1% and 0.5% topical 

ocular reproxalap demonstrated statistically and clinically relevant improvement from baseline in multiple signs and symptoms associated with dry eye 
disease in as soon as one week. In September 2018, we announced that the results of a randomized, vehicle-controlled, parallel-group, multi-center, double-
masked Phase 2b clinical trial of 0.1% and 0.25% topical ocular reproxalap demonstrated statistically significant improvement over vehicle in ocular signs 
and symptoms associated with DED (Figure 1). Relative to patients treated with vehicle, patients treated with the 0.25% concentration of reproxalap 
demonstrated statistically significant and clinically relevant reductions in the Four-Symptom Ocular Dryness Score and the Overall Ocular Discomfort 
Symptom Score. For drug-treated patients, improvement greater than that of vehicle was consistently observed across all symptoms, and activity versus 
vehicle was evident as early as two weeks, the first assessment following initiation of therapy. The early onset of symptomatic improvement is consistent 
with the Phase 2a clinical trial of topical ocular reproxalap in DED, and is supportive of a differentiated product profile relative to standard of care. Patients 
treated with the 0.25% concentration of reproxalap also demonstrated reductions in ocular fluorescein staining score that were statistically superior to those 
of patients treated with vehicle. 

Figure 1: Phase 2b Dry Eye Disease Clinical Trial Results for 0.25% Reproxalap

In April 2019, we initiated the RENEW Trial, an adaptive, two-part, multi-center, randomized, vehicle-controlled, double-masked, parallel-group 
Phase 3 trial of 0.25% topical ocular reproxalap compared to vehicle in patients with moderate to severe DED. The primary objective of RENEW Part 1 
was to confirm dosing regimen, endpoints, and sample size for RENEW Part 2. In Part 1 of RENEW, 422 patients were randomized equally to receive 
either four-times-daily reproxalap or vehicle for twelve weeks (the constant dosing group) or four-times-daily reproxalap or vehicle for four weeks, 
followed by twice-daily reproxalap or vehicle for eight weeks (the induction-maintenance dosing group). In December 2019, we announced that, in the 
induction-maintenance dosing group, the RENEW co-primary endpoint of patient-reported visual analog scale (VAS) ocular dryness from Weeks 2 to 12 
was achieved (p=0.0004) (Figure 2), and that activity was observed as early as one week after initiation of therapy (p=0.001) and was maintained until the 
end of the trial.

Figure 2: RENEW Part 1 Results – Co-Primary Symptom Endpoint for the Induction Maintenance Dosing Regimen

SEM = standard error of the mean; MMRM = mixed model repeated measures

In the induction-maintenance dosing group from Weeks 2 to 12, reproxalap was statistically superior to vehicle in VAS ocular endpoints for itching 

(p=0.03), foreign body sensation (p=0.004), discomfort (p=0.003), photophobia (p=0.004), and pain (p=0.03) (Figure 3). In the induction-maintenance 
dosing group from Weeks 2 to 12, reproxalap was also statistically superior to vehicle in Ocular Discomfort & 4-Symptom Questionnaire ocular endpoints 
for dryness (p=0.01), discomfort (p=0.03), burning (p=0.03), grittiness (p=0.003), and stinging (p=0.02). Although the improvement effect size of the co-
primary endpoint of fluorescein nasal region ocular staining did not reach statistical significance, reproxalap was statistically superior to vehicle in 
reduction from baseline in the induction-maintenance dosing group from Weeks 1 to 4 of treatment (p=0.03), and statistical separation from vehicle was 
observed at Week 2 (p=0.04). Given that the co-primary symptom endpoint was achieved in RENEW Part 1, the RENEW Trial was concluded and 
RENEW Part 2 was not performed.

13

 
 
 
 
 
 
Figure 3: RENEW Part 1 Results – Symptom Treatment Differences Over Weeks 2 to 12 for the Induction Maintenance Dosing Regimen

In February of 2020, we announced that the results of a randomized, vehicle-controlled, parallel-group, multi-center, double-masked Phase 2 clinical 

trial of a novel formulation of 0.25% topical ocular reproxalap demonstrated statistically significant improvement over vehicle for the primary endpoint of 
VAS ocular dryness score (p=0.03). Consistent with the RENEW Trial, the drug was administered via the induction maintenance regimen. The novel 
formulation is substantially similar to the formulations used in the Phase 2b clinical trial and the RENEW Trial, differing only in the amount of a single 
excipient. 

In January 2021, we announced positive top-line symptom, redness, and Schirmer test results from the run-in cohort of the Phase 3 TRANQUILITY 

clinical trial of 0.25% topical ocular reproxalap in patients with DED. Patients were treated with four doses of reproxalap or vehicle for one day. On the 
following day, patients were administered a single dose before entry, and a dose 45 minutes after entry, to a dry eye chamber with minimal humidity, high 
airflow, and forced visual tasking. The run-in cohort, performed at a single center, was double-masked, and randomized 12 patients to receive reproxalap 
and 11 patients to receive vehicle. Over all time points in aggregate in the dry eye chamber, reproxalap demonstrated statistically significant improvement 
over vehicle (p=0.03) in ocular redness, an objective sign of dry eye disease.

In November 2021, we announced achievement of the primary endpoint of ocular redness in a randomized, double-masked, vehicle-controlled Phase 

2 clinical trial of 0.25% topical ocular reproxalap in DED patients. The protocol of the trial was substantially similar to that of the TRANQUILITY run-in 
cohort. The primary endpoint of the trial was achieved: ocular redness scores in the reproxalap group during the dry eye chamber were observed to be 
statistically lower than those of vehicle (p = 0.016, Figure 4). Additionally, Schirmer test scores assessed after the first dose were directionally in favor of 
reproxalap over vehicle and approached statistical significance (p = 0.068).

Figure 4: Phase 2 Dry Eye Chamber Trial Results– Ocular Redness

In December 2021, we announced top-line results from the randomized, double-masked, vehicle-controlled Phase 3 TRANQUILITY Trial of 0.25% 
topical ocular reproxalap in DED. Although the primary endpoint of ocular redness was not met, statistical significance (p=0.0001, Figure 5) was achieved 
for the DED sign of Schirmer test, a secondary endpoint, in favor of reproxalap over vehicle. Statistical significance (p<0.0001) in favor of reproxalap over 
vehicle was also achieved for the post-hoc clinical relevance assessment of proportion of Schirmer test responders that improved from baseline scores (0 to 
30 mm) by at least 10 mm.  

Figure 5: Phase 3 TRANQUILITY Trial Results– Schirmer Test

SEM = standard error of the mean; MMRM = mixed model repeated measures

In addition to the TRANQUILITY Trial, we have initiated the TRANQULITY-2 Trial, the protocol of which is substantially similar to that of 
TRANQUILITY. Using an alpha sharing technique, the primary endpoint of the TRANQUILITY-2 Trial will be met if either Schirmer test or ocular 
redness is statistically significant in favor of reproxalap over vehicle. Top-line results from TRANQUILITY-2 are expected mid-2022.

Per draft FDA guidance, to be considered for regulatory approval in the United States, a product candidate for the treatment of DED must 
demonstrate efficacy in a subjective symptom  (a patient-reported subjective measure of disease severity) in at least two adequate and well-controlled 
clinical trials, and efficacy in an objective sign (an independently assessed objective measure of disease severity) in at least two adequate and well-
controlled clinical trials. We intend to submit the RENEW Part 1 and Phase 2 novel formulation trials to satisfy the symptom efficacy NDA requirements. 
Because either ocular redness or Schirmer test qualifies as a sign of DED, subject to a 

15

 
 
 
 
 
 
discussion with the FDA, we intend to submit a combination of the Phase 2, TRANQUILITY, and TRANQUILITY-2 chamber trials to satisfy the NDA 
sign requirements, depending on whether ocular redness or Schirmer test is achieved in TRANQUILITY-2 or in subsequent clinical trials. If ocular redness 
and Schirmer test is statistically significant in TRANQUILITY-2, then we may elect to submit the NDA with two sign trials in addition to the symptom 
trials. Pending results from TRANQUILITY-2, a dry eye disease safety trial, and regulatory input, we believe that an NDA filing for reproxalap for the 
treatment of DED could occur mid-2022.

In all reproxalap DED clinical trials completed to date, no clinically significant safety findings were observed, and reproxalap was well tolerated. 

Transient and generally mild instillation site discomfort is the most commonly reported adverse event.

Allergic Conjunctivitis 

In February 2016, we announced that the results of a randomized, parallel-group, double-masked, vehicle-controlled conjunctival challenge 
(allergen administered directly to the eye following a single dose of test article) Phase 2a clinical trial of 0.5% topical ocular reproxalap in patients with AC 
demonstrated statistically and clinically significant activity of reproxalap over vehicle in reducing patient-reported ocular itching score (scale 0 to 4), a 
clinical endpoint that has served as the basis for prior AC FDA approvals. In June 2017, we announced that the results of a randomized, parallel-group, 
double-masked, vehicle-controlled, multi-center conjunctival challenge Phase 2b clinical trial of 0.1% and 0.5% topical ocular reproxalap in patients with 
AC demonstrated statistically and clinically significant activity of reproxalap over vehicle in reducing ocular itching. 

In March 2019, we announced that the randomized, double-masked, vehicle-controlled conjunctival challenge Phase 3 ALLEVIATE clinical trial of 
0.25% and 0.5% topical ocular reproxalap in patients with AC met the primary endpoint (patient-reported ocular itching score area under the curve from 10 
to 60 minutes after allergen challenge, p<0.0001) and the key secondary endpoint (proportion of patients that improved by two or more points on the four-
point itching score, p=0.0005) for 0.25% reproxalap (Figure 6).

Figure 6: Phase 3 ALLEVIATE Trial Results for 0.25% Reproxalap

In October 2019, we announced that our randomized, double-masked, vehicle-controlled allergen chamber (aerosolized pollen over 3.5 hours with 

test article dosing just before and 90 minutes after chamber entry) clinical methods trial of topical ocular reproxalap in patients with AC demonstrated that, 
relative to patients treated with vehicle, patients treated with 0.25% or 0.5% topical ocular reproxalap demonstrated statistically significant reduction in 
patient-reported ocular itching (p<0.0001), investigator-assessed ocular redness (p<0.0001), and patient-reported tearing score (p<0.0001). In April 2021, 
we announced that the randomized, double-masked, vehicle-controlled allergen chamber Phase 3 INVIGORATE clinical trial of 0.25% reproxalap in 
patients with AC 

16

 
 
 
 
 
 
(Figure 7) achieved the primary endpoint (patient-reported ocular itching score after the second dose of test article) and all secondary endpoints 
(investigator-assessed ocular redness score and patient-reported ocular tearing score). 

Figure 7: Phase 3 INVIGORATE Trial Results for 0.25% Reproxalap) - Ocular Itching

In 2022, we initiated the randomized, double-masked, vehicle-controlled allergen chamber Phase 3 INVIGORATE-2 Trial of 0.25% topical ocular 

reproxalap in patients with AC.  Pending positive results from INVIGORATE-2, an allergic conjunctivitis safety trial, and regulatory input, we believe that 
we will have met NDA requirements for AC, although we expect that the NDA submission for AC would occur after the NDA submission for DED. In all 
reproxalap allergic conjunctivitis clinical trials completed to date, no clinically significant safety findings were observed, and reproxalap was well tolerated. 
Transient and generally mild instillation site discomfort is the most commonly reported adverse event.

Proliferative Vitreoretinopathy 

Standard of care treatment for PVR results in subsequent retinal detachment surgical rates that approach 40%. In a single-arm, open-label, 

investigator-sponsored Phase 1b clinical trial performed at the Massachusetts Eye and Ear Infirmary, only approximately 20% of patients with PVR treated 
with multiple injections of ADX-2191 required subsequent surgery for retinal detachment (Figure 8). Thus, relative to standard of care, ADX-2191 may 
reduce incidence of retinal detachment following the development of PVR, thereby increasing the probability of preservation of visual function.

17

 
 
Figure 8: Phase 1b ADX-2191 Investigator-Sponsored Clinical Trial

In December 2019, we initiated the Phase 3 GUARD trial, a two-part, multi-center, randomized, controlled, adaptive Phase 3 clinical trial evaluating 

the efficacy of intravitreal injections of ADX-2191 versus standard-of-care for the prevention of PVR. The primary endpoint of GUARD Part 1 is retinal 
detachment rate over six months following initiation of therapy relative to historical detachment rates. In January 2022, we announced completion of 
enrollment in Part 1 of GUARD, and we expect to announce results in the second half of 2022.

Systemic RASP Modulation for the Treatment of Immune-Mediated Diseases

In April 2020, we announced the results of a Phase 1 clinical trial of ADX-629, a first-in-class orally administered RASP modulator. No treatment-
related adverse events were observed at any dose tested, and target engagement was evidenced by statistically lower RASP levels in drug-treated subjects 
relative to controls (Figure 10). Additionally, following ingestion of a controlled high-fat meal, free fatty acids were statistically lower and HDL 
statistically higher in drug-treated subjects relative to placebo-treated subjects. In December 2020, we announced the initiation of three Phase 2 proof-of-
concept clinical trials of ADX-629 in patients with atopic asthma, psoriasis, or COVID-19 infection as part of a systematic strategy to assess activity across 
different types of immunological diseases. Following completion of the Phase 2 clinical trials, subsequent clinical indications may be selected, depending 
on safety and tolerability, clinical signals, cytokine profiles, and RASP levels.

The Science Supporting Our Product Candidates 

Reactive Aldehyde Species 

In response to infection, injury, endogenous and exogenous chemical triggers, heat, and other stimuli, pro-inflammatory RASP are generated 
through a variety of metabolic processes, including alcohol oxidation, enzymatic and non-enzymatic lipid oxidation, and polyamine and sphingosine 
metabolism. RASP appear to effect inflammation signaling via covalent binding to thiol (sulfur-containing) and amine (nitrogen-containing) residues on 
proteins, including receptors and enzymes. RASP-protein adducts directly influence the function of proteins, leading to activation of intracellular 
inflammatory factors, including NF-κB, an important mediator in the inflammatory response, and inflammasomes. In addition, RASP adducts bind to 
Scavenger Receptor A, which also initiates pro-inflammatory signaling and leads to the formation of antibodies against the adducted protein, at least in part 
explaining the presence of host-directed antibodies in autoimmune diseases such as rheumatoid arthritis. Levels of RASP are generally observed to be 
elevated in ocular and systemic inflammatory disease, and thus represent therapeutic targets for immune modulation. 

Because of the inherent toxicity of RASP, most, if not all, living organisms contain enzymes, such as aldehyde reductases and aldehyde 
dehydrogenases, that convert RASP into non-toxic molecules. Genetic mutations in the RASP-metabolizing enzymes cause disease. In Sjögren-Larsson 
Syndrome, for example, mutations in fatty aldehyde dehydrogenase are responsible for skin, neurological, and retinal disease. 

Aside from the stimulation of inflammation, there is no generally accepted biological role of high levels of RASP. Some physiologic molecules have 
RASP forms, including retinaldehyde (a form of Vitamin A) and pyridoxal and pyridoxal phosphate (forms of Vitamin B6), but the activity of physiological 
RASP is highly restricted by chaperone and other proteins that prevent reaction with other molecules, including our RASP modulators. Thus, 
pharmacotherapeutic RASP modulation is expected not to adversely affect normal physiologic processes. Consistent with the lack of accessibility of 
physiologic RASP, our most advanced RASP modulator, reproxalap, which has been administered to approximately 1,500 patients across a number of 
completed clinical trials, has been observed to be generally well tolerated and has not resulted in any serious adverse events. 

The RASP Modulator Platform 

The RASP modulator platform represents a unique and novel pharmacologic approach that, unlike almost all drugs in use today, is not designed to 

directly inhibit or activate a particular protein but instead targets a family of small molecules that in turn affect the activity and structure of many proteins at 
once. RASP modulation, therefore, has the potential to down-regulate pro-inflammatory systems or groups of proteins, and may lead to multiple beneficial 
clinical effects while avoiding toxicity associated with single-target inhibition or activation.

19

 
 
We are currently developing reproxalap, a new chemical entity, and other novel RASP modulators for the treatment of immune-mediated disease. 
Reproxalap is a small molecule designed specifically to bind, and thereby allow for the degradation of, RASP. In in vitro and animal studies, reproxalap 
does not appear to affect most cellular components, including most receptors, enzymes, ion channels, or other proteins. Reproxalap has been shown to 
outcompete cellular constituents to covalently bind and trap RASP. Reproxalap-RASP adducts appear to be rapidly degraded in cellular environments, after 
which neither reproxalap nor RASP are detectable. Outside of biological systems, reproxalap-RASP adducts have shown to be remarkably non-reactive and 
stable, suggesting that reproxalap-RASP binding may be effectively irreversible. By forming covalent drug-RASP adducts that are then degraded, 
reproxalap and other RASP modulators have the potential to substantially lower RASP levels. 

We believe we have been the first to demonstrate the beneficial effects of RASP modulation in a variety of animal models relating to immune-

mediated disease, suggesting that reproxalap and analogs may have potent anti-inflammatory effects that persist hours after administration at a variety of 
different doses relevant to clinical testing.

In mouse models of ocular inflammation and post-surgical healing, topically applied reproxalap ophthalmic solution reduced ocular redness 
and inflammatory cytokines comparable to corticosteroid therapy and slowed the development of corneal haze (fibrosis). (Data presented at 
the Association for Research in Vision and Ophthalmology 2015 Annual Meeting) 

In mice injected with a pro-inflammatory agent known as endotoxin, intraperitoneally administered reproxalap statistically reduced a variety 
of inflammatory cytokines (protein inflammatory mediators), including IL-5, Il-1ß, IL-17, and TNF-α, while up-regulating the primary anti-
inflammatory cytokine, IL-10. Additionally, in models of mouse contact dermatitis (induced by phorbol myristate acetate) and allergic 
contact dermatitis (induced by sensitivity to oxazolone), reproxalap statistically reduced inflammation as measured by edema (swelling). 
(Data presented at the American Academy of Asthma Allergy and Immunology 2015 Annual Meeting) 

In a model of radiation mucositis (oral inflammation) in hamsters, chronic subcutaneous administration of reproxalap reduced healing time 
and decreased fibrosis (scarring). (Data presented at the Multinational Association of Supportive Care in Cancer – International Society of 
Oral Oncology 2015 Annual Meeting) 

In two different mouse models of inflammatory pain, intraperitoneally administered reproxalap dose-dependently reduced nociceptive 
behavior, suggesting that reproxalap down-regulates pain signaling in inflammation. (Data presented at the 2016 International Conference on 
Pain Research and Management) 

In rat cardiomyocyte culture, reproxalap prevented fibrotic transformation, and inhibited NF-κB activation and IL-1ß release. (Data presented 
at the 2016 American Society for Cell Biology Annual Meeting) 

In a mouse model of lung inflammation, intraperitoneal administration of reproxalap reduced infiltration of inflammatory cells and levels of 
pro-inflammatory cytokines in the lung. (Data presented at the 2017 World Congress on Inflammation Annual Meeting)

In a rat model of intraocular inflammation, a single intravitreal injection of ADX-103 reduced the development of retinal pathology. (Data 
presented at the Association for Research in Vision and Ophthalmology 2018 Annual Meeting)

•

In a rat model of diabetic macular edema, intravitreal injection of ADX-103 reduced retinal inflammatory cell infiltration. (Data presented at 
the Association for Research in Vision and Ophthalmology 2018 Annual Meeting)

Thus, we believe that the immune-modulating mechanism of action of RASP modulation is potentially multifactorial – lowering inflammation, 
reducing healing time, diminishing scarring, and mitigating inflammatory pain – and may ameliorate inflammatory disease and deter disease progression in 
different ways simultaneously. 

In addition to the development of reproxalap, we intend to continue the discovery and development of other novel RASP modulators, and we intend 

to continue to develop intellectual property around such molecules. We have identified, synthesized, and tested numerous molecules that may be more 
potent than reproxalap in binding to RASP. We are currently screening novel product candidates to address diseases where topical and systemic 
administration may reduce RASP-mediated pathology. Clinical development of ADX-629 for the treatment of autoimmune and other inflammatory 
diseases began in late 2019.  

The Potential of ADX- 2191 to Prevent Proliferative Vitreoretinopathy and Treat Primary Vitreoretinal Lymphoma

PVR is characterized by excessive replication and pro-inflammatory activity of retinal cells, at least a portion of which synthesize collagen, the 
principal component of scar tissue. Retinal scarring can lead to impairment of vision, including blindness, as well as increased probability of further retinal 
detachments. Methotrexate, the active component of ADX-2191, is a dihydrofolate reductase inhibitor that has been used to treat cancer and autoimmune 
disease. The anti-proliferative and anti-inflammatory properties of dihydrofolate reductase inhibition are well described. In preclinical studies of primary 
cell cultures from PVR patients, dihydrofolate reductase inhibition reduced pathological cell proliferation and scar-like collagen deposition. Thus, the 
observed clinical activity of ADX-2191 in PVR is believed to be the result of down-regulation of aberrant retinal cell proliferation and activity, thereby 
leading to reduced retinal scarring. Initially as an intravenous medication and subsequently as an intraocular injection, methotrexate has also been used for 
decades as an anti-proliferative medication to treat PVRL. The goal of methotrextate therapy in PVRL is to prevent metastasis to the central nervous 
system. 

Intellectual Property and Proprietary Rights 

Overview 

In the United States and abroad, we are building an intellectual property portfolio for reproxalap and other RASP modulators and for therapeutic 

methods of use of methotrexate for the treatment of retinal disease. We currently seek, and intend to continue to seek, patent protection in the United States 
and internationally for our product candidates, methods of use, and processes for manufacture, and for other technologies, where appropriate. Our current 
policy is to actively seek to protect our proprietary position by, among other things, filing patent applications in the United States and abroad relating to 
proprietary technologies that are important to the development of our business. We also rely on, and will continue to rely on, trade secrets, know-how, 
continuing technological innovation and in-licensing opportunities to develop and maintain our proprietary position. We cannot be sure that patents will be 
granted with respect to any of our pending patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that 
any of our existing patents or any patents that may be granted to us in the future will be commercially useful in protecting our technology. 

Our success will depend significantly on our ability to obtain and maintain patent and other proprietary protection for the technologies that we 
consider important to our business, our ability to defend our patents, and our ability to preserve the confidentiality of our trade secrets and operate our 
business without infringing the patents and proprietary rights of third parties. 

21

 
Patent Portfolio 

Our patent portfolio currently includes patents and patent applications covering the composition, formulation, and uses of reproxalap, ADX-103, 
ADX-629, ADX-1612, and other novel compounds. As of December 31, 2021, we owned fifteen United States patents and twelve pending United States 
non-provisional patent applications, as well as numerous foreign counterparts to these patents and patent applications, relating to reproxalap and other 
RASP modulators. Additionally, we have in-licensed certain patents and patent applications relating to ADX-1612, and retain an exclusive license to 
certain patents related to the use of ADX-2191 for the prevention or treatment of a number of retinal indications including, proliferative vitreoretinal 
disease and primary vitreoretinal lymphoma.

We expect the issued reproxalap composition of matter patent in the United States, if the appropriate maintenance, renewal, annuity or other 
governmental fees are paid, to expire in 2028. It is possible that the term of the composition of matter patent in the United States may be extended up to 
five additional years under the provisions of the Hatch-Waxman Act. We expect the foreign reproxalap composition of matter patents, if the appropriate 
maintenance, renewal, annuity or other governmental fees are paid, to expire in 2026. We expect other patent applications in the portfolio, if issued, and if 
the appropriate maintenance, renewal, annuity or other governmental fees are paid, to expire from 2026 to 2034. Reproxalap composition of matter patents 
have been issued in Australia, Canada, China, Europe (validated in approximately 14 member countries), Hong Kong, India, Japan, Mexico, Russia and 
South Korea. Reproxalap composition of matter patent claims are pending in Brazil.

We are developing ADX-1612 pursuant to a License Agreement with Madrigal Pharmaceuticals, Inc. (Madrigal), entered into on December 26, 

2016 (Madrigal Agreement). Pursuant to the Madrigal Agreement, we obtained an exclusive, worldwide license from Madrigal under certain patents and 
patent applications, and other licenses to intellectual property, to develop and commercialize CHP inhibitors, including ADX-1612 and other molecules 
(Madrigal Agreement Products). We have agreed to use our commercially reasonable efforts to develop Madrigal Agreement Products.

In consideration for the rights licensed under the Madrigal Agreement, we paid Madrigal an upfront license fee of $250,000 and are obligated to 

make future regulatory and development and sales-dependent milestone payments to Madrigal of less than $340 million in the aggregate (over 80% of such 
amount being tied to our achievement of increasingly greater annual worldwide net sales milestones), as well as royalty payments to Madrigal at a rate 
which, as a percentage of net sales, is in the high single digits for products containing ADX-1612 and mid-single digits for any other CHP inhibitor 
product. We are also obligated under the Madrigal Agreement to pay Madrigal a percentage of certain sublicense revenue that we receive in connection 
with entering into any sublicensing arrangements with any third parties, at a percentage rate which tiers downward from the mid-twenties to low-single 
digits based on the development stage of the product at the time of the sublicense.

The Madrigal Agreement will remain in effect until all payment obligations under the Madrigal Agreement expire. We may terminate the Madrigal 

Agreement in its entirety or on a Madrigal Agreement Product-by-Madrigal Agreement Product basis with timely notice to Madrigal. Either party may 
terminate the Madrigal Agreement for uncured material breach by the other party or upon certain insolvency or bankruptcy proceedings involving the other 
party, both with timely notice to the other party. In addition, Madrigal has the right to terminate the Madrigal Agreement if we, our affiliates, or 
sublicensees interfere with, challenge the validity or enforceability of, oppose the extension of, or grant of a supplementary protection certificate with 
respect to any of our licensed patents under the Madrigal Agreement. In the event of an early termination of the Madrigal Agreement, all rights licensed 
and developed by us under the Madrigal Agreement may revert back to Madrigal. Each party has agreed to indemnify the other party for certain third party 
claims arising under the Madrigal Agreement.

MEEI Agreement

We are developing ADX-2191 pursuant to an Exclusive License Agreement with Massachusetts Eye and Ear Infirmary (MEEI) originally entered 
into in July 2016 between MEEI and Helio Vision, Inc., as amended, (MEEI Agreement). We assumed the MEEI Agreement in connection with our 2019 
acquisition of Helio Vision.

Pursuant and subject to the MEEI Agreement, we obtained an exclusive, worldwide license from MEEI to develop and commercialize ADX-2191 

under certain patents and patent applications, and other licenses to intellectual property (MEEI Patent Rights). We have agreed to use our commercially 
reasonable efforts to develop ADX-2191 and to meet certain specified effort and achievement benchmarks by certain dates.

In consideration for the rights licensed under the MEEI Agreement, Helio Vision issued MEEI a number of shares of its preferred stock and Helio 

Vision agreed to pay non-creditable non-refundable license maintenance fees to MEEI of $15,000 on each of the second and third anniversary of the MEEI 
Agreement, $25,000 on each of the fourth and fifth anniversary of the MEEI Agreement and $35,000 on the sixth and each subsequent anniversary of the 
MEEI Agreement during the term of such agreement. In addition, Helio Vision was obligated to make future sales-dependent milestone payments to MEEI 
of up to the low seven figures in the aggregate, as well as royalty payments to MEEI at a rate which, as a percentage of net sales, is in the low single digits 
for products that incorporate or use the MEEI Patent Rights in the United States and as a percentage in the low single digits for products that incorporate or 
use the MEEI Patent Rights outside the United States. We are also obligated under the MEEI Agreement to pay MEEI a percentage of certain sublicense 
revenue that we receive in connection with entering into any sublicensing arrangements with any third parties, at a percentage rate which tiers downward 
from low-double digits to mid-single digits based on the date of the sublicense. Following our acquisition of Helio Vision, we became obligated to make 
any future payments owed under the MEEI Agreement. There is no additional equity consideration issuable under the MEEI Agreement.

The MEEI Agreement will remain in effect until the expiration date of the last to expire patent licensed under the MEEI Agreement. We may 

terminate the MEEI Agreement with timely written notice to MEEI. MEEI has the right to terminate the MEEI Agreement if we, subject to certain 
specified cure periods, cease all business operations with respect to licensed products, fail to pay amounts due under the MEEI Agreement, fail to comply 
with certain due diligence obligations, default in our obligation to maintain insurance, one of our officers is convicted of a felony relating to the 
manufacture, use, sale or importation of licensed products, we materially breach any provisions of the MEEI Agreement or in the event of our insolvency 
or bankruptcy.

In the event of an early termination of the MEEI Agreement, all rights licensed and developed by us under the MEEI Agreement may revert back to 

MEEI. We have agreed to indemnify MEEI for certain claims that may arise under the MEEI Agreement.

Confidential Information and Inventions Assignment Agreements 

We currently require and will continue to require each of our employees and consultants to execute confidentiality agreements upon the 

commencement of such individual’s employment, consulting or collaborative relationships with us. These agreements provide that all confidential 
information developed or made known during the course of the relationship with us be kept confidential and not disclosed to third parties except in specific 
circumstances. In the case of employees, the agreements provide that all inventions resulting from such individual’s work performed for us, utilizing our 
property or relating to our business and conceived or completed by the individual during employment shall be our exclusive property to the extent 
permitted by applicable law. Our consulting agreements also provide for assignment to us of any intellectual property resulting from services performed by 
a consultant for us. 

23

 
Manufacturing 

We do not own or operate manufacturing facilities for the production of our product candidates, nor do we have plans to develop our own 
manufacturing operations in the foreseeable future. We currently depend on third-party contract manufacturers for all of our required raw materials, drug 
substance and finished drug product for our preclinical research and clinical trials. We have no immediate plans to purchase, erect, or otherwise create any 
manufacturing facilities to be owned by us for any of these purposes, and intend to continue to depend on third-party contract manufacturers for the 
foreseeable future. We do not have any current contractual relationships for the manufacture of commercial supplies of our product candidates. If our 
product candidates are approved by any regulatory agency, we intend to enter into agreements with third-party contract manufacturers for the commercial 
production at such time. We may utilize third-party consultants to manage our manufacturing contractors. We believe that the active pharmaceutical 
ingredient and other materials needed for the formulation of our product candidates are relatively easy to manufacture, and that multiple suppliers and 
formulators could be employed for this purpose. Further, we believe the raw materials needed for manufacture of our product candidates, as well as other 
components of our formulations, are generally readily available currently from multiple sources. 

Employees 

As of December 31, 2021, we had 12 full-time employees and had engaged a number of consultants. We expect that a number of consultants 
previously engaged in development of our product candidates will participate in ongoing clinical and manufacturing activities. None of our employees is 
represented by a labor union. We have not experienced any work stoppages, and we consider our relations with our employees to be good. 

Human Capital

We recognize that attracting, motivating and retaining talent at all levels is vital to our continued success. Our employees are a significant asset and 
we aim to create an equitable, inclusive and empowering environment in which our employees can grow and advance their careers, with the overall goal of 
developing, expanding and retaining our workforce to support our current pipeline and future business goals. By focusing on employee retention and 
engagement, we also improve our ability to support our clinical trials, our pipeline, our platform technologies, business and operations, and also protect the 
long-term interests of our stockholders. Our success also depends on our ability to attract, engage and retain a diverse group of employees. Our efforts to 
recruit and retain a diverse and passionate workforce include providing competitive compensation and benefits packages and ensuring we listen to our 
employees.

24

 
We value innovation, passion, data-driven decision making, persistence and honesty, and are building a diverse environment where we believe that 

our employees thrive and are inspired to contribute to the development of novel therapies.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, motivating, and integrating our existing and future 

employees. The principal purpose of our incentive plans is to increase shareholder value by attracting, retaining, and motivating employees, consultants, 
and directors through grants of stock-based compensation awards and payments of cash-based performance bonus awards. We are committed to providing a 
competitive and comprehensive benefits package to our employees. Our benefits package is designed to meet the individual health and wellness needs of 
our employees. We plan to continue to refine our efforts related to optimizing our use of human capital as we grow, including improvements in the way we 
hire, develop, motivate, and retain employees.

Government Regulation 

FDA Approval Process 

In the United States, pharmaceutical products are subject to extensive regulation by the FDA. The Food Drug and Cosmetic Act (FDCA) and other 
federal and state statutes and regulations, govern, among other things, the research, development, testing, manufacture, storage, recordkeeping, approval, 
labeling, promotion and marketing, distribution, post-approval monitoring and reporting, sampling, and import and export of pharmaceutical products. 
Failure to comply with applicable FDA or other requirements may subject a company to a variety of administrative or judicial sanctions, such as the FDA’s 
refusal to approve pending applications, a clinical hold, warning letters, recall or seizure of products, partial or total suspension of production, withdrawal 
of the product from the market, injunctions, fines, civil penalties or criminal prosecution. 

FDA approval is required before any new drug, new dosage form, new therapeutic use, or new route of administration of a previously approved 

product, can be marketed in the United States. The process required by the FDA before a new drug product may be marketed in the United States generally 
involves: 

•

•

•

•

•

•

•

•

•

completion of preclinical laboratory and animal testing and formulation studies in compliance with the FDA’s good laboratory practice (GLP) 
regulation; 

submission to the FDA of an Investigational New Drug application (IND) for human clinical testing which must become effective before 
human clinical trials may begin in the United States; 

approval by an independent institutional review board (IRB) at each site where a clinical trial will be performed before the trial may be 
initiated at that site; 

performance of adequate and well-controlled human clinical trials in accordance with current good clinical practices (cGCP) to establish the 
safety and efficacy of the proposed product candidate for each intended use; 

submission to the FDA of a new drug application (NDA) which must be accepted for filing by the FDA;

satisfactory completion of an FDA pre-approval inspection(s) of our office and the facility or facilities at which the product is manufactured 
to assess compliance with the FDA’s current Good Manufacturing Practices (cGMP) regulations; 

satisfactory completion of an FDA advisory committee review, if applicable; 

payment of user fees, if applicable; and 

FDA review and approval of the NDA. 

The preclinical and clinical testing and approval process requires substantial time, effort, and financial resources. Preclinical tests include laboratory 
evaluation of product chemistry, formulation, manufacturing and control procedures, and stability, as well as animal studies to assess the toxicity and other 
safety characteristics of the product. The results of preclinical tests, together with manufacturing information, analytical data, and a proposed clinical trial 
protocol and other information, are submitted as part of an IND to the FDA. Preclinical testing may 

25

 
continue even after the IND is submitted. The IND becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, 
raises concerns or questions and places the clinical trial on a partial or complete clinical hold. In such a case, the IND sponsor and the FDA must resolve 
any outstanding concerns before the clinical trial can begin. As a result, our submission of an IND may not result in FDA authorization to commence a 
clinical trial. A separate submission to an existing IND must also be made for each successive clinical trial conducted during product development. Even if 
the IND becomes effective and the trial proceeds without initial FDA objection, the FDA may stop the trial at a later time if, among other reasons, the 
potential for unacceptable safety risks arises. 

Further, an independent IRB, covering each site proposing to conduct the clinical trial must review and approve the plan for any clinical trial and 

informed consent information for subjects before the trial commences at that site 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 or for failure to comply with the FDA’s or IRB’s requirements. Other conditions may also be imposed. 

Clinical trials involve the administration of the investigational new product to human subjects under the supervision of qualified investigators in 
accordance with GCP requirements, which include the requirement that all research subjects provide informed consent in writing for participation in the 
clinical trial. Sponsors of clinical trials generally must register and report, at the NIH-maintained website ClinicalTrials.gov, key parameters and results of 
certain clinical trials. For purposes of an NDA submission and approval, human clinical trials are typically conducted in the following sequential phases, 
which may overlap or be combined: 

•

•

•

•

Phase 1: The investigational drug product is initially introduced into healthy human subjects or patients and tested for safety, dose tolerance, 
absorption, metabolism, distribution, and excretion. 

Phase 2: The investigational drug product is administered to a limited patient population to identify possible adverse effects and safety risks, 
to preliminarily evaluate the efficacy of the product for specific targeted indications, and to determine dose tolerance and optimal dosage. 
Multiple Phase 2 clinical trials may be conducted by the sponsor to obtain information prior to beginning larger and more extensive clinical 
trials. 

Phase 3: When Phase 2 evaluations suggest that certain dosing regimens may be efficacious and may have an acceptable safety profile, Phase 
3 trials may be undertaken in larger patient populations to further evaluate dosage and to obtain evidence of potential clinical efficacy and 
safety. Phase 3 trials may include multiple, geographically-dispersed clinical trial sites. Data generated from these studies may be used to 
establish the overall risk-benefit profile of the investigational drug product and to provide adequate information for the labeling of the 
product, if approved. 

Phase 4: In some cases, the FDA may condition approval of an NDA for a product candidate on the sponsor’s commitment to conduct 
additional clinical trials to further assess the product’s safety and/or effectiveness after NDA approval. Such post-approval trials are typically 
referred to as Phase 4 trials. 

The results of product development, preclinical studies and clinical trials are submitted to the FDA as part of an NDA. NDAs must also contain 

extensive information relating to the product’s pharmacology, chemistry, manufacturing and controls, and proposed labeling, among other things. 

For some products, the FDA may require a risk evaluation and mitigation strategy (REMS) which could include measures imposed by the FDA such 

as prescribing restrictions, requirements for post-marketing studies, and reporting or certain restrictions on distribution and use. Under federal law, the 
submission of most NDAs is additionally subject to a substantial application user fee, and the manufacturer and/or sponsor under an approved NDA are 
also subject to prescription drug program fees. The FDA has 60 days from its receipt of an NDA to determine whether the application will be accepted for 
filing based on the agency’s threshold determination that it is sufficiently complete to permit substantive review. The FDA may request additional 
information rather than accept an NDA for filing. In this event, the NDA must be resubmitted with the additional information and is subject to payment of 
additional user fees. The resubmitted application is also subject to review before the FDA accepts it for filing. 

26

 
Once the submission has been accepted for filing, the FDA begins an in-depth substantive review. Under the Prescription Drug User Fee Act 

(PDUFA), the FDA agrees to specific performance goals for NDA review time through a two-tiered classification system, Standard Review and Priority 
Review. Standard Review NDAs have a goal of being completed within a ten-month timeframe after acceptance of filing. A Priority Review designation is 
given to products that offer major advances in treatment or provide a treatment where no adequate therapy exists. The goal for completing a Priority 
Review is six months after acceptance of filing. 

It is likely that our product candidates will be granted a Standard Review. The review process may be extended by the FDA for three additional 

months to consider certain information or obtain clarification regarding information already provided in the submission. The FDA may refer applications 
for novel products or products which present difficult questions of safety or efficacy to an advisory committee for review, evaluation, and recommendation 
as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendation of an advisory committee, but 
it considers such recommendations carefully when making decisions. In addition, for combination products, the FDA’s review may include the participation 
of both the FDA’s Center for Drug Evaluation and Research, the Center for Biologics Evaluation and Research, and the FDA’s Center for Devices and 
Radiological Health. The participation of multiple distinct groups within the FDA has the potential to complicate or prolong review of the application. If 
the product is deemed a combination product, additional supporting studies may be required, and may delay an NDA submission.

Before approving an NDA, the FDA may inspect our offices and the facility or facilities where the drug substance or drug product is manufactured. 
The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP. FDA may also 
inspect sponsor facilities to determine if nonclinical and clinical studies were conducted in compliance with applicable regulations and guidelines. 

After the FDA evaluates the NDA and, in some cases, the related manufacturing facilities, it may issue an approval letter or a Complete Response 
Letter (CRL) to indicate that the review cycle for an application is complete and that the application is not ready for approval. CRLs generally outline the 
deficiencies in the submission and may require substantial additional testing or information in order for the FDA to reconsider the application. Even with 
submission of this additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval. If and 
when the deficiencies have been addressed to the FDA’s satisfaction, the FDA may issue an approval letter. An approval letter authorizes commercial 
marketing of the product with specific prescribing information for specific indications. 

Once issued, the FDA may withdraw product approval if ongoing regulatory requirements are not met or if potential adverse safety findings are 

identified after the product reaches the market. In addition, the FDA may require post-approval testing, including Phase 4 studies, and surveillance 
programs to monitor the effect 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 post-marketing programs. 

Products may be promoted only for the approved labeled indications and in accordance with the provisions of the approved label, and, even if the 

FDA approves a product, it may limit the approved indications for use for the product or impose other conditions, including labeling or distribution 
restrictions or other risk-management mechanisms, such as a Black Box Warning, which highlights a specific warning. Further, if there are any 
modifications to the product, including changes in indications, labeling, or manufacturing processes or facilities, a company would be required to submit 
and obtain FDA approval of a new or supplemental NDA, which may require the company to develop additional data or conduct additional preclinical 
studies and clinical trials. 

Post-Approval Requirements 

Once an NDA is approved, a product will be subject to pervasive and continuing regulation by the FDA, including, among other things, 
requirements relating to product/facility listing, recordkeeping, periodic reporting, product sampling and distribution, advertising and promotion and 
reporting of adverse experiences with the product. 

In addition, drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to register their 

establishments with the FDA and state agencies, and are subject to periodic 

27

 
unannounced inspections by the FDA and these state agencies for compliance with cGMP requirements. Changes to the manufacturing process are strictly 
regulated and may require prior FDA approval before being implemented. FDA regulations may also require investigation and correction of any deviations 
from cGMP and may impose reporting and documentation requirements upon us and any third-party manufacturers. Accordingly, manufacturers must 
continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. 

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements and standards is not maintained or if 

problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of 
unanticipated seriousness, severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in, among 
other things: 

•

•

•

•

•

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls; 

fines, warning letters or holds on post-approval clinical trials; 

refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of product license 
approvals; 

product seizure or detention, or refusal to permit the import or export of products; or 

injunctions or the imposition of civil or criminal penalties. 

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. The FDA does not regulate the 
practice of medicine. Physicians may prescribe for off-label uses; manufacturers may only promote for the approved indications and in accordance with the 
provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off label uses, and a 
company that is found to have improperly promoted off label uses may be subject to significant liability, both at the federal and state levels. 

The Food and Drug Administration Amendments Act of 2007 gave the FDA the authority to require a Risk Evaluation and Mitigation Strategy, or 

REMS, from manufacturers to ensure that the benefits of a drug or biological product outweigh its risks. In determining whether a REMS is necessary, 
FDA must consider the size of the population likely to use the drug, the seriousness of the disease or condition to be treated, the expected benefit of the 
drug, the duration of treatment, the seriousness of known or potential adverse events, and whether the drug is a new molecular entity. If the FDA 
determines a REMS is necessary, the drug sponsor must agree to the REMS plan at the time of approval. A REMS may be required to include various 
elements, such as a medication guide or patient package insert, a communication plan to educate health care providers of the drug’s risks, limitations on 
who may prescribe or dispense the drug, or other measures that the FDA deems necessary to assure the safe use of the drug. In addition, the REMS must 
include a timetable to assess the strategy at 18 months, three years, and seven years after the strategy’s approval. The FDA may also impose a REMS 
requirement on a drug already on the market if the FDA determines, based on new safety information, that a REMS is necessary to ensure that the drug’s 
benefits outweigh its risks. 

Orphan Drug Designation 

The FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition, which is defined as a disease or condition that 

affects fewer than 200,000 individuals in the United States or more than 200,000 individuals where there is no reasonable expectation that the product 
development cost will be recovered from product sales in the United States. Orphan drug designation must be requested before submitting an NDA and 
does not convey any advantage in, or shorten the duration of, the regulatory review or approval process. ADX-2191 has received orphan designation for the 
prevention of PVR, and for the treatment of PVRL and for the treatment of retinitis pigmentosa.

If an orphan drug-designated product subsequently receives the first FDA approval for the disease specified in the orphan drug designation, the 

sponsor will be entitled to seven years of product marketing exclusivity, which 
28

 
means that the FDA may not approve any other applications to market the same drug for the same indication, except in very limited and rare circumstances, 
for seven years. If a competitor obtains approval of the same drug, as defined by the Orphan Drug Act, before we do or if our product candidate is 
determined to be contained within the competitor’s product for the same indication or disease, the competitor’s exclusivity could block the approval of our 
product candidate in the designated orphan indication for seven years, unless superior safety or efficacy of our drug is demonstrated. 

Patent Term Restoration and Marketing Exclusivity 

Depending upon the timing, duration, and specifics of FDA approval of the use of our drug candidates, some of our United States patents may be 
eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman 
Act. The Hatch-Waxman Act permits a patent restoration term of up to five years as compensation for patent term lost during product development and the 
FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the 
product’s approval date. The patent term restoration period is generally one-half the time between the effective date of an IND, and the submission date of 
an NDA, plus the time between the submission date of an NDA and the approval of that application. Only one patent applicable to an approved drug is 
eligible for the extension and the application for extension must be made prior to expiration of the patent. The United States Patent and Trademark Office, 
in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. In the future, we intend to apply for 
restorations of patent term for some of our currently owned or licensed patents to add patent life beyond the current expiration date, depending on the 
expected length of clinical trials and other factors involved in the submission of the relevant NDA. 

Market exclusivity provisions under the FDCA also can delay the submission or the approval of certain applications. The FDCA provides a five-

year period of non-patent marketing exclusivity within the United States to the first applicant to gain approval of an NDA for a new chemical entity. A drug 
is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule responsible 
for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an abbreviated new drug application (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, an application may be submitted after four years if it contains a certification of patent invalidity or non-
infringement. The FDCA also provides three years of marketing exclusivity for a 505(b)(1) NDA, 505(b)(2) NDA, or supplement to an approved NDA if 
new clinical investigations other than bioavailability studies (e.g., investigations that support new indications, dosages, or strengths of an existing drug) 
were conducted or sponsored by the applicant and are deemed by the FDA to be essential to the approval of the application. The three-year exclusivity 
covers only the conditions associated with the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs containing the 
original active agent. Five-year and three-year exclusivity will not delay the submission or approval of a full 505(b)(1) NDA. 

Manufacturing Requirements 

We and our third-party manufacturers must comply with applicable FDA regulations relating to FDA’s cGMP regulations and, if applicable, quality 

system regulation requirements for medical devices. The cGMP regulations include requirements relating to, among other things, organization of personnel, 
buildings and facilities, equipment, control of components and drug product containers and closures, production and process controls, packaging and 
labeling controls, holding and distribution, laboratory controls, records and reports, and returned or salvaged products. The manufacturing facilities for our 
products must meet cGMP requirements to the satisfaction of the FDA and may be subject to a pre-approval inspection before we can use them to 
manufacture our products. We and our third-party manufacturers are also subject to periodic unannounced inspections of facilities by the FDA and other 
authorities, including procedures and operations used in the testing and manufacture of our products to assess our compliance with applicable regulations. 
Failure to comply with statutory and regulatory requirements subjects a manufacturer to possible legal or regulatory action, including, among other things, 
warning letters, voluntary corrective action, the seizure of products, injunctions, consent decrees placing significant restrictions on or suspending 
manufacturing operations and civil and criminal penalties. 

29

 
Other Regulatory Requirements 

We are also subject to various laws and regulations regarding laboratory practices, the experimental use of animals, and the use and disposal of 

hazardous or potentially hazardous substances in connection with our research. In each of these areas, as above, the FDA has broad regulatory and 
enforcement powers, including, among other things, the ability to levy fines and civil penalties, suspend or delay issuance of approvals, seize or recall 
products, and withdraw approvals, any one or more of which could have an adverse effect on our ability to operate our business and generate revenues. 
Compliance with applicable environmental laws and regulations is expensive, and current or future environmental regulations may impair our research, 
development and production efforts, which could harm our business, operating results and financial condition. There are evolving legal requirements and 
other statutory and regulatory regimes that will continue to affect our business. 

Research and Development Expenses 

Substantially all of our research and development expenses incurred to date have been related to the development of reproxalap and our other 

product candidates. Our research and development expenses totaled $44.9 million for the year ended December 31, 2021 and $24.7 million for the year 
ended December 31, 2020. 

We anticipate that we will incur additional research and development expenses in the future as we evaluate and possibly pursue the development of 

our product candidates for additional indications, or develop additional product candidates. 

We recognize research and development expenses as they are incurred. Our research and development expenses consist primarily of: 

•

•

•

•

•

•

•

•

salaries and related expenses for personnel; 

fees paid to consultants and contract research organizations in conjunction with independently monitoring clinical trials and acquiring and 
evaluating data in conjunction with clinical trials, including all related fees such as investigator grants, patient screening, lab work and data 
compilation and statistical analysis; 

costs incurred with third parties related to the establishment of a commercially viable manufacturing process for our product candidates; 

costs related to production of clinical materials, including fees paid to contract manufacturers; 

costs related to upfront, milestone payments under in-licensing agreements as well as costs for unapproved inventory for which there is no 
future alternative use; 

costs related to compliance with FDA regulatory requirements; 

consulting fees paid to third-parties involved in research and development activities; and 

costs related to stock options or other stock-based compensation granted to personnel in development functions. 

We expense both internal and external development costs as they are incurred. 

30

 
We expect that a large percentage of our research and development expenses in the future will be incurred in support of our current and future non-

clinical, preclinical and clinical development programs. These expenditures are subject to numerous uncertainties in terms of both their timing and total 
cost to completion. We expect to continue to develop stable formulations of our product candidates, test such formulations in preclinical studies for 
toxicology, safety and efficacy and to conduct clinical trials for each product candidate. We anticipate funding clinical trials for our product candidates 
ourselves, but we may engage collaboration partners at certain stages of clinical development. As we obtain results from clinical trials, we may elect to 
discontinue or delay clinical trials for certain product candidates or programs in order to focus our resources on more promising product candidates or 
programs. Completion of clinical trials by us or our future collaborators may take several years or more, the length of time generally varying with the type, 
complexity, novelty and intended use of a product candidate. The costs of clinical trials may vary significantly over the life of a project owing to but not 
limited to the following: 

•

•

•

•

•

•

•

•

the number of sites included in the trials; 

the length of time required to enroll eligible patients; 

the number of patients that participate in the trials; 

the number of doses that patients receive; 

the drop-out or discontinuation rates of patients; 

the duration of patient follow-up; 

the phase of development the product candidate is in; and 

the efficacy and safety profile of the product candidate. 

Our expenses related to clinical trials are based on estimates of the services received and efforts expended pursuant to contracts with multiple 
research institutions and contract research organizations that conduct and manage clinical trials on our behalf. The financial terms of these agreements are 
subject to negotiation and vary from contract to contract and may result in uneven payment flows. Generally, these agreements set forth the scope of work 
to be performed at a fixed fee or unit price. Payments under the contracts depend on factors such as the successful enrollment of patients or the completion 
of clinical trial milestones. Expenses related to clinical trials generally are accrued based on contracted amounts applied to the level of patient enrollment 
and activity according to the protocol. If timelines or contracts are modified based upon changes in the clinical trial protocol or scope of work to be 
performed, we modify our estimates of accrued expenses accordingly on a prospective basis. 

None of our product candidates have received FDA or foreign regulatory marketing approval. In order to grant marketing approval, a health 
authority such as the FDA or foreign regulatory agencies must conclude that clinical and preclinical data establish the safety and efficacy of our product 
candidates with an appropriate benefit to risk profile relevant to a particular indication, and that the product can be manufactured under cGMP in a 
reproducible manner to deliver the product’s intended performance in terms of its stability, quality, purity and potency. Until our submission is reviewed by 
a health authority, there is no way to predict the outcome of their review. Even if the clinical studies meet their predetermined primary endpoints, and a 
registration dossier is accepted for filing, a health authority could still determine that an appropriate benefit to risk relationship does not exist for the 
indication that we are seeking. 

We cannot forecast with any degree of certainty which of our product candidates will be subject to future collaborations or how such arrangements 

would affect our development plan or capital requirements. 

As a result of the uncertainties discussed above, we are unable to determine the duration and completion costs of our development projects or when 

and to what extent we will receive cash inflows from the commercialization and sale of an approved product candidate.

•

Our business is dependent in large part on the successful development and commercialization of a single product candidate, reproxalap, for 
which we are researching multiple indications. We cannot be certain that we will be able to obtain regulatory approval for, or successfully 
commercialize, reproxalap.

To generate revenue, we will depend on FDA approval and successful commercialization of our lead product candidate, reproxalap, for the 
treatment of dry eye disease. If we are unable to successfully conduct the TRANQUILITY-2 trial, prepare and timely submit the planned NDA, 
and obtain FDA approval, our ability to generate revenue will be significantly delayed.

• We have incurred significant operating losses since inception and we expect to incur significant losses for the foreseeable future. We may never 

become profitable or, if achieved, be able to sustain profitability.

• We will require substantial additional financing, and a failure to obtain this necessary capital when needed on acceptable terms, or at all, could 

force us to delay, limit, reduce, or terminate our product development, other operations or commercialization efforts.

•

•

•

Reproxalap and our other product candidates are subject to extensive regulation, compliance with which is costly and time consuming, and such 
regulation may cause unanticipated delays, or prevent the receipt of the required approvals to commercialize our product candidates.

If our competitors develop treatments for the target indications of our product candidates that are approved more quickly than ours, marketed to 
physicians and patients more effectively or comprehensively, contracted with payors more successfully, or demonstrated to be safer or more 
effective than our product candidates, our commercial opportunity will be reduced or eliminated.

If we fail to develop and commercialize our product candidates, we may be unable to grow our business.

• We rely on third parties to conduct our clinical trials. If any third party does not meet our deadlines or otherwise conduct the trials as required 
and in accordance with regulations, our clinical development programs could be delayed or unsuccessful and we may not be able to obtain 
regulatory approval for or successfully commercialize our product candidates when expected, or at all.

•

Public health emergencies, epidemics or pandemics, such as the ongoing COVID-19 pandemic, may impact our business.  

Risks Related to our Business

Our business is dependent in large part on the successful development and commercialization of a single product candidate, reproxalap, for which we 
are researching multiple indications. We cannot be certain that we will be able to obtain regulatory approval for, or successfully commercialize, 
reproxalap. 

Our product candidates, including reproxalap, will require additional preclinical studies, substantial clinical development and testing, and regulatory 
approval prior to commercialization. We have not yet completed development of any product candidate. We have only one product candidate that has been 
the focus of significant 

33

 
 
clinical development: reproxalap, a novel small molecule chemical entity that is believed to inhibit RASP, a toxic chemical species suspected to cause and 
exacerbate numerous diseases in humans and animals. We are dependent in large part on successful continued development and ultimate regulatory 
approval and successful commercialization of reproxalap for our future business success. Any negative results or perceived negative results in clinical trials 
for one indication may have an adverse effect on our ability to develop and potentially commercialize reproxalap for the treatment of another indication. 
We have invested, and will continue to invest, a significant portion of our time and financial resources in the development of reproxalap and, if successful, 
the commercialization of reproxalap. We will need to raise sufficient funds for, and successfully enroll and complete, our current and planned clinical trials 
of reproxalap and our other product candidates. The future regulatory and commercial success of our product candidates is subject to a number of risks, 
including the following: 

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

we may not have sufficient financial and other resources to pursue our business plans, complete necessary clinical trials, and create a 
commercial infrastructure; 

we may not be able to provide sufficient evidence of safety and efficacy to continue a development program or obtain regulatory approval; 

the results of our clinical trials may not meet the endpoints, or level of statistical or clinical significance required by the FDA, or comparable 
foreign regulatory bodies, for marketing approval;

the safety and efficacy results of our later phase or larger clinical trials may not confirm the results of our earlier trials; 

patients in our clinical trials may demonstrate greater response rates or improvements from vehicle or in the non-treatment arm then was 
expected when designing and powering our clinical trials;

there may be variability in patients, adjustments to clinical trial procedures, and inclusion of additional clinical trial sites; 

the initial parts of adaptive clinical trials are not designed to be pivotal or definitive, and as such we may not satisfy the designated endpoints 
and also may need to revise the design or endpoints to achieve success in later parts of the trial or potentially abandon the trial;

we may not be able to timely or adequately finalize the design or formulation of any product candidate or demonstrate that a formulation of 
our product candidate will be stable for commercially reasonable time periods; 

the FDA, or comparable foreign regulatory bodies, may implement new standards, or change the interpretation of existing standards or 
requirements for the regulatory approval, in general or with respect to the indications our product candidates are being developed to treat; 

the FDA, or comparable foreign bodies, may require clinical data in addition to the clinical trial programs we expect or may require changes 
to the designs and endpoints of the subsequent clinical trials;

patients in clinical trials for our product candidates may suffer adverse effects or die for reasons that may or may not be related to our product 
candidates; 

if approved for certain diseases, our product candidates will compete with well-established and other products or therapeutic options already 
approved for marketing by the FDA, or comparable foreign regulatory bodies; 

competitive products may be more effectively or comprehensively marketed to physicians or patients, or contracted with payors more 
successfully;

we may be adversely affected by legislative or regulatory reform of the health care system in the United States or other jurisdictions in which 
we may do business; and 

we may not be able to obtain, maintain, or enforce our patents and other intellectual property rights. 

Of the large number of drugs in development in the pharmaceutical industry, only a small percentage result in the submission of an NDA to the 

FDA, and even fewer are approved for commercialization. We are currently 

34

 
 
planning to submit an NDA to the FDA for reproxalap in DED in mid-2022, pending results from TRANQUILITY-2, a dry eye disease safety trial, and 
regulatory input. Even if our trials are successful, we can provide no assurances that the FDA will accept our NDA for review. Moreover, even if the FDA 
does accept our NDA for review, there can be no assurance that the FDA will agree with our interpretation of the data, that the FDA will not require us to 
conduct additional clinical trials or provide additional data, or that the FDA will approve our NDA in a timely fashion, or at all.

Furthermore, even if we do receive regulatory approval to market reproxalap and our other product candidates, any such approval may be subject to 

limitations on the indicated uses for which we may market the product. Accordingly, even if we are able to obtain the requisite financing to continue to 
fund our development programs, we cannot assure that reproxalap and our other product candidates will be successfully developed or commercialized. If 
we or any of our future development partners are unable to develop, or obtain regulatory approval for or, if approved, successfully commercialize, 
reproxalap and our other product candidates, we may not be able to generate sufficient revenue to continue our business.

To generate revenue, we will depend on FDA approval and successful commercialization of our lead product candidate, reproxalap, for the treatment 
of dry eye disease. If we are unable to successfully conduct the TRANQUILITY-2 trial, prepare and timely submit the planned NDA, and obtain FDA 
approval, our ability to generate revenue will be significantly delayed.

Our ability to generate revenue will depend on the successful development, regulatory approval and commercialization of reproxalap. Based on our 

discussions with and our interpretation of feedback from the FDA, as well as data from our previously completed clinical trials in dry eye disease and the 
TRANQUILITY-2 trial, we currently plan to submit an NDA to the FDA for reproxalap for the potential treatment of dry eye disease in mid-2022, subject 
to positive clinical trial results, including results from a dry eye disease safety trial. There can be no assurance that we can prepare and submit an NDA in a 
timely manner or at all. We have limited experience in preparing, filing, and pursuing applications necessary to gain regulatory approvals. The preparation 
of an NDA requires a great deal of effort and expertise, and if we do not secure the necessary resources and hire and retain personnel having the requisite 
expertise to prepare and submit the NDA, the filing of the NDA would be delayed. Further, if an NDA is submitted by the company, there can be no 
assurance that it will be accepted for filing by the FDA. If the FDA determines after an initial review of the NDA that the data included in the application is 
insufficient and not ready for formal consideration, we could receive a “refuse to file” notice. The FDA has substantial discretion in the approval process 
and may disagree with our interpretation of or the sufficiency of the data from our clinical trials. The FDA could also require that we conduct additional 
studies and submit the results of those studies before the application will be reconsidered, which would require us to expend more resources than we 
planned or that are available to us, and could substantially delay any approval of our application. It is also possible that additional studies may not suffice to 
make our application approvable. Even if the NDA is accepted for filing by the FDA, there can be no assurance that it would be approved in a timely 
manner or at all.

Issues with product quality could have a material adverse effect upon our business, subject us to regulatory actions and cause a loss of customer 
confidence in us or our products.

Our success depends upon the quality of our products. Quality controls, assurance, and management plays an essential role in meeting customer 

requirements, preventing defects, improving our product candidates and services, and assuring the safety and efficacy of our product candidates. Our future 
success depends on our ability to maintain and continuously improve our quality management program. A quality or safety issue may result in adverse 
inspection reports, warning letters, product recalls or seizures, monetary sanctions, injunctions to halt manufacture and distribution of products, civil or 
criminal sanctions, costly litigation, refusal of a government to grant approvals and licenses, restrictions on operations, or withdrawal of existing approvals 
and licenses. An inability to address a quality or safety issue in an effective and timely manner may also cause negative publicity, a loss of customer 
confidence in us or our future products, which may result in difficulty in successfully launching product candidates and the loss of sales, which could have 
a material adverse effect on our business, financial condition, and results of operations.

35

 
 
 
 
In order to commercialize our product candidates, we will need to substantially grow the size of our organization. We may encounter difficulties in 
managing our growth and expanding our operations successfully. 

Because, as of December 31, 2021, we only had 12 full-time employees, we will need to grow our organization to continue development and pursue 
the potential commercialization of reproxalap and our other product candidates, as well as function as a public company. As we seek to advance reproxalap 
and other product candidates towards potential commercialization, increase the number of ongoing product development programs, and advance our future 
product candidates through preclinical studies and clinical trials, we will need to expand our financial, development, regulatory, manufacturing, marketing, 
and sales capabilities, or contract with third parties to provide these capabilities for us. As our operations expand, we expect that we will need to manage 
additional relationships with various strategic partners, suppliers, and other third parties. Future growth will impose significant added responsibilities on 
members of management and require us to retain additional internal capabilities. Our future financial performance and our ability to commercialize our 
product candidates and to compete effectively will depend, in part, on our ability to manage any future growth effectively. To that end, we must be able to 
manage our development efforts and clinical trials effectively and hire, train, and integrate additional management, clinical and regulatory, financial, 
administrative and sales, and marketing personnel. We may not be able to accomplish these tasks, and our failure to so accomplish could prevent us from 
successfully growing our company.

We are highly dependent on the services of our senior management team and certain key consultants. 

As a company with a limited number of personnel, we are highly dependent on the development, regulatory, commercial, and financial expertise of 

our senior management team comprised of three individuals: Todd C. Brady, M.D., Ph.D., our President and Chief Executive Officer; Joshua Reed, 
M.B.A., our Chief Financial Officer; and Stephen G. Machatha, Ph.D., our Chief Development Officer, as well as certain other employees. In addition, we 
rely on the services of a number of key consultants, including IP, pharmacokinetic, chemistry, toxicology, drug development, and commercialization 
consultants. The loss of such individuals or the services of future members of our management team could delay or prevent the further development and 
commercialization of our product candidates and, if we are not successful in finding suitable replacements, could harm our business.  

If we fail to attract and retain senior management and key commercial personnel, we may be unable to successfully develop or commercialize our 
product candidates. 

We will need to expand and effectively manage our managerial, operational, financial, and other resources in order to successfully pursue our 

clinical development and commercialization efforts. Our success also depends on our continued ability to attract, retain, and motivate highly qualified 
management and scientific personnel, and we may not be able to do so in the future due to intense competition among biotechnology and pharmaceutical 
companies, universities, and research organizations for qualified personnel. If we are unable to attract and retain the necessary personnel, we may 
experience significant impediments to our ability to implement our business strategy. 

We expect to expand our management team. Our future performance will depend, in part, on our ability to successfully integrate newly hired 
executive officers into our management team and our ability to develop an effective working relationship among senior management. Our failure to 
integrate these individuals and create effective working relationships among them and other members of management could result in inefficiencies in the 
development and commercialization of our product candidates, adversely affecting future regulatory approvals, sales of our product candidates, and results 
of our operations.

Our employees, independent contractors, vendors, principal investigators, CROs, and consultants may engage in misconduct or other improper 
activities, including noncompliance with regulatory standards, regulatory requirements, and insider trading. 

We are exposed to the risk that our employees, independent contractors, vendors, principal investigators, CROs and consultants may engage in 

fraudulent conduct or other illegal activity. Misconduct by these parties could include:

•

intentional, reckless, or negligent conduct or disclosure to us of unauthorized activities that violate the regulations of the FDA or similar 
foreign regulatory authorities;

36

 
 
•

•

•

healthcare fraud and abuse in violation of U.S. and foreign laws and regulations;

violations of U.S. federal securities laws relating to trading in our common stock; and

failures to report financial information or data accurately.

In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent 
fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations govern a wide range of pricing, discounting, marketing 
and promotion, sales commission, customer incentive programs and other business arrangements. While we have adopted a code of conduct and 
implemented other internal controls applicable to all our employees, it is not always possible to identify and deter misconduct by employees and other third 
parties, and the precautions we take to detect and prevent this activity may not be effective. Additionally, we are subject to the risk that a person could 
allege fraud or other misconduct, even if none occurred. If any such actions are instituted against us, and we are not successful in defending ourselves or 
asserting our rights, those actions could have a significant impact on our business or cause reputational harm, including the imposition of civil, criminal and 
administrative penalties, and damages; possible exclusion from participation in Medicare, Medicaid, and other federal healthcare programs; and diminished 
profits and future earnings. 

In addition, during the course of our operations, our directors, executives, employees, consultants, and other third parties may have access to 
material nonpublic information regarding our business, our results of operations, or potential transactions we are considering. We may not be able to 
prevent trading in our common stock on the basis of, or while having access to, material nonpublic information. If any such person was to be investigated 
or an action were to be brought against them for insider trading, it could have a negative impact on our reputation and our stock price. Such a claim, with or 
without merit, could also result in substantial expenditures of time and money, and divert attention of our management team from other tasks important to 
the success of our business. 

Our business is subject to political, economic, legal, and social risks, which could adversely affect our business.

There are significant regulatory, economic and legal barriers in markets in the United States and outside the United States that we must overcome. 
We may be subject to the burden of complying with a wide variety of national and local laws, including multiple and possibly overlapping and conflicting 
laws. We also may experience difficulties adapting to new cultures, business customs, and legal systems. Any sales and operations would be subject to 
political, economic, and social uncertainties including, among others:

•

•

•

•

•

•

•

•

changes and limits in import and export controls; 

increases in custom duties and tariffs; 

changes in currency exchange rates; 

economic and political instability; 

the impact on employees, suppliers, customers, and the global economy related to public health epidemics or pandemics, such as the COVID-
19 pandemic, and actions taken in response to such events; 

changes in government regulations and laws; 

absence in some jurisdictions of effective laws to protect our intellectual property rights; and 

currency transfer and other restrictions and regulations that may limit our ability to sell certain products or repatriate profits to the United 
States. 

Changes in United States social, political, regulatory, and economic conditions or in laws and policies governing foreign trade, manufacturing, 
development, and investment, and any negative sentiments towards the United States as a result of such changes, could adversely affect our business. 

37

 
Any changes related to these and other factors could adversely affect any business operations that we conduct outside the United States. 

If we engage in an acquisition, reorganization, or business combination, we will incur a variety of risks that could adversely affect our business 
operations or our stockholders. 

From time to time, we have entered into, and we will continue to consider in the future, strategic business initiatives intended to further the 
development of our business. These initiatives may include acquiring businesses, technologies, or products, or entering into a business combination with 
another company. For example, in January 2019 we acquired Helio Vision, Inc. and obtained the rights to ADX-2191, a vitreous-compatible methotrexate 
formulation for intraocular injection, for the prevention of PVR. Any acquisitions we undertake or have recently completed will likely be accompanied by 
business risks which may include, among other things:  

•

•

•

•

•

•

•

•

the effect of the acquisition on our financial and strategic position and reputation;

the failure of an acquisition to result in expected benefits, which may include benefits relating to new product candidates, human resources, 
costs savings, operating efficiencies, goodwill, and other synergies;

the difficulty, cost, and management effort required to integrate the acquired businesses, including costs and delays in implementing common 
systems and procedures, and costs and delays caused by communication difficulties;

the assumption of certain known or unknown liabilities of the acquired business, including litigation-related liabilities;

the reduction of our cash available for operations and other uses, the increase in amortization expense related to identifiable assets acquired, 
potentially dilutive issuances of equity securities, or the incurrence of debt;

the possibility that we will pay more than the value we derive from the acquisition;

the impairment of relationships with our partners, consultants, or suppliers, or those of the acquired business; and

the potential loss of key employees of the acquired business.

These factors could harm our business, results of operations, or financial condition.

In addition to the risks commonly encountered in the acquisition of a business or assets as described above, we may also experience risks relating to 

the challenges and costs of closing a transaction. The risks described above may be exacerbated as a result of managing multiple acquisitions at once. 

Security breaches, loss of data, and other disruptions to us or our third-party service providers could compromise sensitive information related to our 
business or prevent us from accessing critical information and expose us to liability, which could adversely affect our business and our reputation.

In the ordinary course of our business, we and our third-party service providers collect and store sensitive data, including legally protected health 
information, personally identifiable information about patients, intellectual property, and our proprietary business and financial information. We manage 
and maintain data utilizing a combination of on-site systems, managed data center systems, and cloud-based data center systems. We face a number of risks 
related to our protection of, and our service providers’ protection of, this critical information, including loss of access, inappropriate disclosure and 
inappropriate access, as well as risks associated with our ability to identify and audit such events.

The secure processing, storage, maintenance and transmission of critical information is vital to our operations and business strategy, and we devote 

significant resources to protecting such information. Although we take measures to protect sensitive information from unauthorized access or disclosure, 
our information technology and infrastructure may be vulnerable to attacks by hackers or viruses or otherwise breached due to employee error, 

38

 
malfeasance, or other activities. These risks may be heightened during the ongoing COVID-19 pandemic, should any of our employees voluntarily choose 
to work remotely. While we are not aware of any such attack or breach, if such event would occur and cause interruptions in our operations, our networks 
would be compromised and the information we store on those networks could be accessed by unauthorized parties, publicly disclosed, lost, or stolen. Any 
such access, disclosure or other loss of information could result in legal claims or proceedings, liability under federal, state, and international laws that 
protect the privacy of personal information, such as the Health Insurance Portability and Accountability Act of 1966, or HIPAA, and regulatory penalties. 
In addition, we may be subject to state laws requiring notification of affected individuals and state regulators in the event of a breach of personal 
information, which is a broader class of information than the health information protected by HIPAA. Unauthorized access, loss, or dissemination of critical 
information could also disrupt our ability to conduct research and development activities; collect, process, and prepare company financial information; 
provide information about our product candidates and other patient and physician education or outreach efforts through our website; manage the 
administrative aspects of our business; or prevent damage to our reputation, any of which could adversely affect our business.

We generally seek to comply with industry standards and are subject to the terms of our privacy policies and privacy-related obligations to third 
parties. We strive to comply with all applicable laws, policies, legal obligations, and industry codes of conduct relating to privacy and data protection to the 
extent possible. However, it is possible that these obligations may be interpreted and applied in a manner that is inconsistent from one jurisdiction to 
another and may conflict with other rules or our practices. Any failure or perceived failure by us to comply with applicable privacy and data security laws 
and regulations, our privacy policies, or our privacy-related obligations to third parties, or any compromise of security that results in the unauthorized 
release or transfer of personal information or other sensitive data, may result in governmental enforcement actions, litigation, or public statements against 
us by consumer advocacy groups or others and could cause a loss of trust in us, which would have an adverse effect on our reputation and business.

In addition, the interpretation and application of consumer, health-related and data protection laws in the United States, Europe, and elsewhere are 

often uncertain, contradictory and in flux. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our practices. If 
so, this could result in government-imposed fines or orders requiring that we change our practices, which could adversely affect our business. In addition, 
we are subject to various state laws, including the California Consumer Privacy Act, or CCPA, which, among other things, requires covered companies to 
provide disclosures to California consumers concerning the collection and sale of personal information, and gives such consumers the right to opt-out of 
certain sales of personal information.  The CCPA provides for civil penalties for violations, as well as a private right of action for security breaches that 
may increase the likelihood of, and the risks associated with, security breach litigation. Additionally, in November 2020, California passed the California 
Privacy Rights Act, or CPRA, which expands the CCPA significantly, including by expanding consumers’ rights with respect to certain personal 
information and creating a new state agency to oversee implementation and enforcement efforts, potentially resulting in further uncertainty and requiring us 
to incur additional costs and expenses in an effort to comply. Many of the CPRA’s provisions will become effective on January 1, 2023. Further, Virginia 
enacted the Virginia Consumer Data Protection Act, or CDPA, and, most recently, Colorado passed the Colorado Privacy Act, or CPA, both comprehensive 
state privacy laws with an effective date of July 1, 2023. The CCPA, CPRA, CDPA, and CPA may increase our compliance costs and potential liability, 
particularly in the event of a data breach, and could have a material adverse effect on our business, including how we use personal information, our 
financial condition, and the results of our operations. The CCPA has also prompted a number of proposals for new federal and state privacy legislation that, 
if passed, could increase our potential liability, increase our compliance costs and adversely affect our business.

Recent developments in Europe have created compliance uncertainty regarding the processing of personal data from Europe. For example, the 

General Data Protection Regulation, or GDPR, which became effective in the European Union (EU) on May 25, 2018, applies to our activities conducted 
from an establishment in the EU or related EU data subject.  The GDPR creates new compliance obligations applicable to our business, which could cause 
us to change our business practices, and increases financial penalties for noncompliance (including possible fines of up to 4% of global annual turnover for 
the preceding financial year or €20 million, whichever is higher, for the most serious infringements). Further, as of January 1, 2021, and the expiry of 
transitional arrangements agreed to between the United Kingdom (UK) and EU, data processing in the United Kingdom is governed by a United Kingdom 
version of the GDPR (combining the GDPR and the Data Protection Act 2018), exposing us to two 

39

 
 
parallel sets of regulations, each of which potentially authorizes similar fines and other potentially divergent enforcement actions for certain violations. The 
GDPR and UK GDPR require, among other things, that personal information only be transferred outside of the European Economic Area, or the EEA, or 
the UK, respectively, to jurisdictions that have not been deemed adequate by the European Commission or by the UK data protection regulator, 
respectively, including the United States, if certain safeguards are taken to legitimize those data transfers. Recent legal developments in the EU have 
created complexity and uncertainty regarding such transfers. These recent developments require us to review and amend our uses of Standard Contractual 
Clauses involving the transfer of data covered by the GDPR or UK GDPR outside of the EU or UK, which could increase our compliance costs and 
adversely affect our business. As a result, we may need to modify the way we treat such information.

In addition to the EU and UK, a growing number of other global jurisdictions are considering or have passed legislation implementing data 
protection requirements or requiring local storage and processing of data or similar requirements that could increase the cost and complexity of our 
business. Some of these laws, such as the General Data Protection Law in Brazil, or the Act on the Protection of Personal Information in Japan, impose 
similar obligations as those under the GDPR. Others, such as those in Russia, India, and China, could potentially impose more stringent obligations, 
including data localization requirements. If we are unable to meet these evolving legal requirements or if we violate or are perceived to violate any laws, 
regulations, or other obligations relating to privacy, data protection, or information security, we may harm to our reputation and become subject to 
investigations, claims, and other remedies, which would expose us to significant fines, penalties, and other damages, all of which would harm our business.

Our internal computer systems, or those of our development partners, third-party clinical research organizations, or other contractors or consultants, 
may fail or suffer security breaches, which could result in a material disruption of our product development programs. 

Despite the implementation of security measures, our internal computer systems and those of our current and any future Contract Research 
Organizations (CROs) and other contractors, consultants, and collaborators are vulnerable to damage from computer viruses, unauthorized access, natural 
disasters, terrorism, war or other military conflict, including an escalation of the conflict between Russia and Ukraine, and telecommunication and electrical 
failures. While to our knowledge we have not experienced any such material system failure, accident, or security breach to date, if such an event were to 
occur and cause interruptions in our operations, it could result in a material disruption of our development programs and our business operations. For 
example, the loss of clinical trial data from completed or future clinical trials could result in delays in our regulatory approval efforts and significantly 
increase our costs to recover or reproduce the data. Likewise, we rely on third parties to manufacture our product candidates and conduct clinical trials, and 
similar events relating to their 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 liability and the further development and commercialization of our product candidate could be delayed. 

We rely on email and other messaging services in connection with our operations. We may be targeted by parties using fraudulent spoofing and 
phishing emails to misappropriate passwords, payment information, or other personal information, or to introduce viruses through Trojan horse programs or 
otherwise through our networks, computers, smartphones, tablets, or other devices. Despite our efforts to mitigate the effectiveness of such malicious email 
campaigns through a variety of control and non-electronic checks, spoofing and phishing may damage our business and increase our costs. These risks may 
be heightened during the ongoing COVID-19 pandemic, should any of our employees voluntarily choose to work remotely. In addition, due to the political 
uncertainty involving Russia and Ukraine, there is an increased likelihood that escalation of tensions could result in cyberattacks that could either directly 
or indirectly impact our operations. Any of these events or circumstances could materially adversely affect our business, financial condition, and operating 
results.

Risks Related to our Financial Position and Capital Requirements

We have incurred significant operating losses since inception and we expect to incur significant losses for the foreseeable future. We may never become 
profitable or, if achieved, be able to sustain profitability. 

We have incurred significant operating losses since we were founded in 2004 and expect to incur significant losses for the next several years as we 
continue our clinical trial, development programs, and commercial activities for reproxalap and our other product candidates. Net loss for the year ended 
December 31, 2021 and 2020 was approximately $57.8 million and $37.6 million, respectively. As of December 31, 2021, we had total stockholders’ 
equity of $205.7 million and an accumulated deficit of $294.7 million. Losses have resulted principally from costs incurred in our clinical trials, research 
and development programs and from general and administrative expenses. In the future, we intend to continue to conduct research and development, 
clinical testing, regulatory compliance activities, pre-commercial activities, and, if reproxalap or any of our other product candidates is approved, 
commercialization efforts, including sales and marketing activities, that, together with anticipated general and administrative expenses, will likely result in 
our incurring further significant losses for the next several years. 

We currently generate no revenue from sales, and we may never be able to commercialize reproxalap or our other product candidates. We do not 

currently have the required approvals to market any of our product candidates and we may never receive them. We may not be profitable even if we or any 
of our future development partners succeed in obtaining regulatory approval and commercialize any of our product candidates. Because of the numerous 
risks and uncertainties associated with developing and commercializing our product candidates, we are unable to predict the extent of any future losses or 
when we will become profitable, if at all. 

We will require substantial additional financing, and a failure to obtain this necessary capital when needed on acceptable terms, or at all, could force 
us to delay, limit, reduce or terminate our product development, other operations or commercialization efforts. 

The development and commercialization of biopharmaceutical products is capital intensive.  We are advancing reproxalap and our other product 

candidates through preclinical and clinical development, including multiple ongoing and planned clinical trials for our product candidates. We expect our 
expenses to increase in connection with our ongoing activities as we continue the research and development of, and, if successful, seek marketing approval 
for, our product candidates. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant 
commercialization expenses related to manufacturing, product sales, marketing, and distribution. We may also need to raise additional funds sooner if we 
choose to pursue additional indications for our product candidates or otherwise expand more rapidly than we presently anticipate. Furthermore, we expect 
to continue to incur additional costs associated with operating as a public company. Accordingly, we will need to obtain substantial additional funding in 
connection with our continuing operations. If we are unable to raise capital when needed on attractive terms, if at all, we will be forced to delay, reduce, or 
eliminate certain of our clinical development plans, research and development programs or future commercialization efforts.  In addition, there can be no 
assurance that we will be able to obtain such financing on commercially reasonable terms or at all. The development process for our product candidates is 
highly uncertain, and we cannot estimate with certainty the actual amounts necessary to successfully complete the development, regulatory approval, and 
commercialization of our product candidates. Our operating plans may change as a result of many factors currently unknown to us, and we may need to 
seek additional funds sooner than expected, through public or private equity, debt financings, or other sources. The amount and timing of any expenditure 
needed to implement our development and commercialization programs will depend on numerous factors, including: 

•

•

the type, number, scope, progress, expansion costs, results, and timing of our clinical trials of reproxalap or any our other product candidates 
that we are pursuing or may choose to pursue in the future; 

the need for, and the progress, costs, and results of, any additional clinical trials of reproxalap and our other product candidates we may 
initiate based on the results of our planned clinical trials or discussions 

41

 
with the FDA, including any additional trials the FDA or other regulatory agencies may require evaluating the safety or efficacy of 
reproxalap and our other product candidates; 

the costs of obtaining, maintaining, and enforcing our patents and other intellectual property rights; 

the costs and timing of obtaining or maintaining manufacturing for reproxalap and our other product candidates, including commercial 
manufacturing, if any product candidate is approved; 

the costs and timing of establishing sales and marketing capabilities and enhanced internal controls over financial reporting; 

the terms and timing of establishing collaborations, license agreements, and other partnerships on terms favorable to us; 

costs associated with any other product candidates that we may develop, in-license, or acquire, including potential milestone or royalty 
payments; 

the effect of competing technological and market developments; 

our ability to establish and maintain partnering arrangements for development; and 

the costs associated with being a public company. 

•

•

•

•

•

•

•

•

Some of these factors are outside of our control. Our existing capital resources are not sufficient to enable us to fund the completion of our clinical 

trials and remaining development through commercial introduction. We expect that we will need to raise substantial additional funds in the near future. 

We have not sold any products, and we do not expect to sell or derive revenue from any product sales for the foreseeable future. We may seek 
additional funding through collaboration agreements and public or private financings, including debt financings. The state of the global economy and 
market instability has made the business climate volatile and more costly. Uncertain economic conditions, uncertainty as to the general direction of the 
macroeconomic environment, and the price of our common stock, are beyond our control and may make any necessary debt or equity financing more 
difficult, more costly, and more dilutive. Additional funding may not be available to us on acceptable terms, or at all. In addition, the terms of any financing 
may adversely affect the holdings or the rights of our stockholders or be excessively dilutive. In addition, the issuance of additional shares by us, or the 
possibility of such issuance, may cause the market price of our shares to decline. 

If we are unable to obtain funding on a timely basis, we will be unable to complete the planned clinical trials for reproxalap and our other product 
candidates, and we may be required to significantly curtail, delay, or discontinue one or more of our preclinical studies, clinical trials or other research or 
development programs, or the commercialization of any product candidate. We may also be unable to expand our operations or otherwise capitalize on our 
business opportunities, may need to restructure our organization, or may be required to relinquish rights to our product candidates or other technologies, or 
otherwise agree to terms unfavorable to us. Any of these occurrences could materially affect our business, financial condition, and results of operations. 

Raising additional capital may cause dilution to stockholders, restrict our operations or require us to relinquish rights to its technologies or product 
candidates.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity 

offerings, debt financings, collaborations, strategic alliances, licensing arrangements, and marketing and distribution arrangements. To the extent that we 
raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of these securities 
may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing and preferred equity financing, if 
available, may involve agreements that include covenants limiting or restricting its ability to take specific actions, such as incurring additional debt, making 
capital expenditures, or declaring dividends.

If we raise additional funds through collaborations, strategic alliances, licensing arrangements or marketing and distribution arrangements, we may 

have to relinquish valuable rights to our technologies, future revenue 

42

 
 
 
streams, research programs, or product candidates, or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds 
through equity or debt financings when needed, we may be required to delay, limit, reduce, or terminate its product development or future 
commercialization efforts or grant rights to develop and market products or product candidates that we would otherwise prefer to develop and market on 
our own.

We may allocate our cash and cash equivalents in ways that you and other stockholders may not approve. 

Our management has broad discretion in the application of our cash and cash equivalents. Because of the number and variability of factors that will 

determine our use of our cash and cash equivalents, management’s ultimate use of cash and cash equivalents may vary substantially from the currently 
intended use. Our management might not apply our cash and cash equivalents in ways that ultimately increase the value of your investment. We expect to 
use our cash and cash equivalents to: fund our planned clinical trials of reproxalap and our other product candidates; fund potential NDA submissions; fund 
an initial commercialization of reproxalap, if approved; develop other molecules that relate to immune-mediated disease; pursue regulatory approval for our 
product candidates; service our debt obligations; and provide working capital and capital for other general corporate purposes. The failure by our 
management to apply these funds effectively could harm our business. We may invest our cash and cash equivalents in short-term, investment-grade, 
interest-bearing securities. These investments may not yield a favorable return to our stockholders. If we do not invest or apply our cash and cash 
equivalents in ways that enhance stockholder value, we may fail to achieve expected financial results, which could cause our stock price to decline.  

The terms of our secured debt facility require us to meet certain operating covenants and place restrictions on our operating and financial flexibility. If 
we raise additional capital through debt financing, the terms of any new debt could further restrict our ability to operate our business. 

In March 2019, we entered into a credit facility with Hercules Capital, which was subsequently amended in April 2021, that is secured by a lien 
covering all of our assets, other than our intellectual property. The loan agreement contains customary affirmative and negative covenants and events of 
default. Affirmative covenants include, among others, covenants requiring us to maintain our legal existence and governmental approvals, deliver certain 
financial reports, and maintain insurance coverage. Negative covenants include, among others: restrictions on transferring any part of our business or 
intellectual property; incurring additional indebtedness; engaging in mergers or acquisitions; paying dividends or making other distributions; making 
investments; and creating other liens on our assets, in each case subject to customary exceptions. If we raise any additional debt financing, the terms of 
such additional debt could further restrict our operating and financial flexibility. These restrictions may include, among other things, limitations on 
borrowing and specific restrictions on the use of our assets, as well as prohibitions on our ability to create liens, pay dividends, redeem capital stock, or 
make investments. If we default under the terms of the Hercules Credit Facility or any future debt facility, the lender may accelerate all of our repayment 
obligations and take control of our pledged assets, potentially requiring us to renegotiate our agreement on terms less favorable to us or to immediately 
cease operations. Further, if we are liquidated, the lender’s right to repayment would be senior to the rights of the holders of our common stock. The lender 
could declare a default upon the occurrence of any event that they interpret as a material adverse effect as defined under the loan agreement. Any 
declaration by the lender of an event of default could significantly harm our business and prospects and could cause the price of our common stock to 
decline. If we raise any additional debt financing, the terms of such additional debt could further restrict our operating and financial flexibility. 

Our ability to use net operating loss carryforwards and tax credit carryforwards to offset future taxable income may be limited as a result of 
transactions involving our common stock. 

In general, under Section 382 of the Internal Revenue Code of 1986, as amended, a corporation that undergoes an “ownership change” is subject to 
limitations on its ability to utilize its pre-change net operating losses (NOLs) and certain other tax assets (tax attributes) to offset future taxable income. In 
general, an ownership change occurs if the aggregate stock ownership of certain stockholders increases by more than 50 percentage points over such 
stockholders’ lowest percentage ownership during the testing period (generally three years). Transactions involving our common stock within the testing 
period, even those outside our control, such as purchases or sales by investors, could result in an ownership change. A limitation on our ability to utilize 
some or all of our NOLs or credits could have a material adverse effect on our results of operations and cash flows. We believe, prior to December 31, 2020 
43

 
 
 
that three ownership changes occurred since inception, and that a fourth ownership change was triggered during the year ended December 31, 2021.  
Management believes that its aggregate Section 382 limitation (including the additional limitation for recognized "built-in gains") is sufficient so that no 
current impairment of its pre-ownership change tax attributes is required. Any future ownership changes, including those resulting from our recent or future 
financing activities, may cause our existing tax attributes to have additional limitations. Any future ownership changes, including those resulting from our 
recent or future financing activities, may cause our existing tax attributes to have additional limitations. However, subject to annual limitations, Federal 
NOLs generated in years 2018 and beyond will have an indefinite carryforward period and will not expire. Future changes in federal and state tax laws 
pertaining to NOL carryforwards may also cause limitations or restrictions from us claiming such NOLs. If the NOL carryforwards become unavailable to 
us or are fully utilized, our future taxable income will not be shielded from federal and state income taxation absent certain U.S. federal and state tax 
credits, and the funds otherwise available for general corporate purposes would be reduced. 

Governments may impose price controls, which may adversely affect our future profitability. 

We intend to seek approval to market our product candidates in both the United States and in foreign jurisdictions. If we obtain approval in one or 
more foreign jurisdictions, we will be subject to rules and regulations in those jurisdictions relating to our product candidates. In some foreign countries, 
particularly in the EU, 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 candidate. To obtain reimbursement or pricing 
approval in some countries, we, or our collaborators, may be required to conduct a clinical trial that compares the cost-effectiveness of our drug to other 
available therapies. Furthermore, in some European countries, the authorities conduct a Health Technology Appraisal to assess the cost-effectiveness of the 
product, which may significantly impact effective access to the market.  If reimbursement of our future products is unavailable or limited in scope or 
amount, or if pricing is set at unsatisfactory levels, we may be unable to achieve or sustain profitability. 

Business disruptions could seriously harm our future revenues and financial condition and increase our costs and expenses. 

Our operations could be subject to business disruptions such as earthquakes, power shortages, telecommunications failures, water shortages, floods, 
hurricanes, typhoons, fires, extreme weather conditions, public health epidemics (including the COVID-19 pandemic), regional or larger scale conflicts or 
geo-political actions, war or other military conflict, including an escalation of the conflict between Russia and Ukraine, trade policies, sanctions, treaties 
and tariffs and other natural or man-made disasters or other business interruptions, for which we are predominantly self-insured. The occurrence of any of 
these business disruptions could seriously harm our operations and financial condition, and increase our costs and expenses. We rely on third-party 
manufacturers to produce reproxalap and our other product candidates. Our ability to obtain clinical and commercial supplies of reproxalap or our other 
product candidates could be disrupted, if the operations of these suppliers are affected by these business disruptions. 

Our quarterly operating results may fluctuate significantly. 

We expect our operating results to be subject to quarterly fluctuations. Our net loss and other operating results will be affected by numerous factors, 

including: 

•

•

•

•

•

•

variations in the level of expenses related to our clinical trial and development programs; 

addition or termination of clinical trials or development programs; 

any intellectual property infringement lawsuit in which we may become involved; 

regulatory developments affecting reproxalap and our other product candidates; 

the impact of the COVID-19 pandemic on our business, results of operations, and financial position;

our establishment and maintenance of a sales, marketing and distribution infrastructure to commercialize any product candidate for which we 
may obtain marketing approval;

44

 
•

•

•

•

our execution of any collaborative, licensing, or similar arrangements, and the timing of payments we may make or receive under these 
arrangements; 

the number of administrative, clinical, regulatory, and scientific personnel we engage; 

nature and terms of stock-based compensation grants; and

derivative instruments recorded at fair value. 

If our quarterly operating results fall below the expectations of investors or securities analysts, the price of our common stock could decline 
substantially. Furthermore, any quarterly fluctuations in our operating results may, in turn, cause the price of our stock to fluctuate substantially. We believe 
that quarterly comparisons of our financial results are not necessarily meaningful and should not be relied upon as an indication of our future performance. 

Risks Related to the COVID-19 Pandemic

Our business has been and will continue to be adversely affected by the COVID-19 pandemic.

The global spread of COVID-19, and variants thereof, has created significant volatility, uncertainty, and economic disruption. The extent to which 

the COVID-19 pandemic impacts our business, operations, and financial results will depend on numerous evolving factors that we may not be able to 
accurately predict, including: the duration and scope of the pandemic; governmental, business and individuals’ actions that have been and continue to be 
taken in response to the pandemic; the impact of the pandemic on economic activity and actions taken in response; the effect on our ongoing or planned 
clinical trials; and any closures of our offices or clinical trial facilities. Any of these events could cause or contribute to the risks and uncertainties 
enumerated in this annual report on Form 10-K and could materially adversely affect our business, financial condition, results of operations, and/or stock 
price.

We are closely monitoring the impact of the COVID-19 pandemic on all aspects of our business, including how it will impact our employees, 

clinical trials, development programs, supply chain, and other aspects of our operations. For example, patient enrollment in our GUARD trial, was 
negatively impacted as a result of limited clinical trial staffing at study sites and some patients electing to delay surgery. While COVID-19 did not have a 
material adverse effect on our reported results for the year ended December 31, 2021, we are unable to predict the ultimate impact that it may have on our 
business, future results of operations, financial position, or cash flows. The extent to which our operations may be impacted by the COVID-19 pandemic 
will depend largely on future developments, which are highly uncertain and cannot be accurately predicted, including new information which may emerge 
concerning the severity of the outbreak and actions by government authorities to contain the outbreak or diminish its impact. 

We have experienced operational interruptions as a result of the COVID-19 pandemic, with certain of our employees electing to work remotely to 
avoid spread of the disease. Our offices are currently open as allowed under state and local orders. While we have implemented what we believe to be a 
reasonable protocol to ensure the safety and wellbeing of employees returning to the office, these measures may not be sufficient to mitigate the risks posed 
by the virus or otherwise be satisfactory to government authorities. A prolonged pandemic, or the threat thereof, could result in lower productivity, 
voluntary closure of our office, and other disruptions to our business. We may also incur additional costs to remedy damages caused by business 
disruptions, including clinical trial delays or interruptions. Any of these could have a material adverse effect on our business, financial condition, or results 
of operations.

Due to the evolving and highly uncertain nature of this event, we cannot predict at this time the full extent to which the COVID-19 pandemic will 

adversely impact our business, results, or financial condition, which will depend on many factors that are not known at this time. These include, among 
others, the extent of harm to public health, the continued disruption to clinical trials, and the impact of the global business and economic environment on 
liquidity, and the availability of capital. We are staying in close communication with our employees, CROs, and suppliers, and acting to mitigate the impact 
of this dynamic and evolving situation, but there is no guarantee that we will be able to do so.

45

 
 
To the extent the COVID-19 pandemic or any worsening of the global business and economic environment as a result thereof adversely affects our 

business and financial results, it may also have the effect of heightening or exacerbating many of the other risks described in this section of this annual 
report on Form 10-K.

COVID-19 has and is expected to continue to affect our ability to recruit or retain patients for our clinical trials, disrupt our supply chains, or have 
other adverse effects on our business and operations.

In addition to those who have been directly affected by COVID-19, millions more have been affected by government efforts around the world to 
slow the spread of the pandemic through quarantines, travel restrictions, heightened border scrutiny, and other measures. The outbreak and government 
measures taken in response to the COVID-19 pandemic have also had a significant impact, both direct and indirect, on businesses and commerce, as worker 
shortages have occurred; supply chains have been disrupted; facilities and production have been suspended; the capital markets and the economy in general 
has been volatile; and demand for certain goods and services, such as medical services and supplies, has spiked, while demand for other goods and services, 
such as travel, has fallen. The future progression of the outbreak, including the emergence of COVID-19 variants, and its effects on our business and 
operations are uncertain. We have and expect to continue to face difficulties recruiting or retaining patients in our ongoing and planned clinical trials due to 
actions taken by governments and individuals in response to the COVID-19 pandemic. Patient enrollment in our GUARD trial was negatively impacted as 
a result of limited clinical trial staffing at study sites and some patients electing to delay surgery. We and our third-party contract manufacturers, contract 
research organizations, and clinical sites may also face disruptions in procuring items that are essential for our research and development activities, 
including, for example, medical and laboratory supplies used in our clinical trials or preclinical studies, in each case, that are sourced from abroad or for 
which there are shortages because of ongoing efforts to address the pandemic.

Risks Related to the Development and Commercialization of our Product Candidates

Reproxalap and our other product candidates are subject to extensive regulation, compliance with which is costly and time consuming, and such 
regulation may cause unanticipated delays, or prevent the receipt of the required approvals to commercialize our product candidates. 

The clinical development, manufacturing, labeling, storage, record-keeping, advertising, promotion, import, export, marketing, and distribution of 

our product candidates are subject to extensive regulation by the FDA in the United States and by comparable authorities in foreign markets. In the United 
States, we are not permitted to market our product candidates until we receive regulatory approval from the FDA. The process of obtaining regulatory 
approval is expensive and time-consuming, and can vary substantially based upon the type, complexity, and novelty of the products involved, as well as the 
target indication, and patient population. Approval policies or regulations may change, and the FDA has substantial discretion in the drug approval process, 
including the ability to delay, limit, or deny approval of a product candidate for many reasons. Despite the time and expense invested in clinical 
development of product candidates, regulatory approval, and subsequent commercial success is uncertain and not guaranteed. 

Reproxalap and our other product candidates, and the activities associated with development and commercialization, including testing, manufacture, 

safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale, and distribution, are subject to extensive regulation by the FDA 
and other regulatory agencies in the United States and by comparable authorities in other jurisdictions. 

Our ongoing research and development activities and planned clinical development and commercialization for our product candidates may be 

delayed, modified, or ceased for a variety of reasons, including: 

•

•

•

determining that a product candidate is ineffective or potentially causes harmful side effects during preclinical studies or clinical trials; 

difficulty establishing predictive preclinical models for demonstration of safety and efficacy of a product candidate in one or more potential 
therapeutic areas for clinical development; 

patients in our clinical trials may demonstrate greater response rates or improvements from vehicle or standard of care than was expected 
when designing and powering our clinical trials;

46

 
•

•

•

•

•

•

•

•

•

delays resulting from or additional protocols being required as result of the COVID-19 pandemic;

lack of availability of, or difficulty recruiting and retaining, a sufficient number of patients to adequately power our clinical trials;

difficulties in manufacturing a product candidate, including the inability to manufacture a product candidate in a sufficient quantity, suitable 
form, or in a cost-effective manner, or under processes acceptable to the FDA for marketing approval or commercial sale; 

the proprietary rights of third parties, which may preclude us from developing or commercializing a product candidate; 

determining that a product candidate may be uneconomical for us to develop or commercialize, or may fail to achieve market acceptance or 
adequate pricing or reimbursement; 

our expectations regarding our expenses and revenue, the sufficiency or use of our cash resources, and needs for additional financing;

a safety concern or signal may arise that triggers a clinical hold;

our inability to secure strategic partners which may be necessary for advancement of a product candidate into clinical development or 
commercialization; or 

our prioritization of other indications or product candidates for advancement. 

The FDA or comparable foreign regulatory authorities can delay, limit, or deny approval of a product candidate for many reasons, including but not 

limited to: 

•

•

•

•

•

•

•

•

•

•

•

such authorities may disagree with the design or implementation of our or any of our future development partners’ clinical trials, including 
the endpoints of our clinical trials; 

such authorities may require clinical data in addition to clinical trial programs we expect, or may require changes to the designs and 
endpoints of subsequent clinical trials;

a competitor product may have patent protection or another type of market exclusivity that delays approval of our product;

we or any of our future development partners may be unable to demonstrate to the satisfaction of the FDA or other regulatory authorities that 
a product candidate is safe and effective for any indication; 

such authorities may not accept clinical data from trials if conducted at clinical facilities or in countries where the standard of care is 
potentially different from the United States; 

the results of clinical trials may not demonstrate the safety or efficacy required by such authorities for approval; 

we or any of our future development partners may be unable to demonstrate that a product candidate’s clinical and other benefits outweigh its 
safety risks; 

such authorities may disagree with our interpretation of data from preclinical studies or clinical trials or the design of such trials or require 
additional trials and data; 

changes in the leadership or operation of such authorities, which may result in, among other things, the implementation of new standards, or 
changes to the interpretation or enforcement of existing regulatory standards and requirements; 

such authorities may find deficiencies in the manufacturing processes or facilities of third-party manufacturers with which we or any of our 
future development partners contract for clinical and commercial supplies; or 

the approval policies, standards, or regulations of such authorities may significantly change in a manner rendering our or any of our future 
development partners’ clinical data insufficient for approval. 

47

 
With respect to foreign markets, approval procedures vary among countries and, in addition to the aforementioned risks, can involve additional 
product testing, administrative review periods, and agreements with pricing authorities. In addition, events raising questions about the safety of certain 
marketed pharmaceuticals may result in increased cautiousness by the FDA and comparable foreign regulatory authorities in reviewing new drugs based on 
safety, efficacy, or other regulatory considerations and may result in significant delays in obtaining regulatory approvals. Any delay in obtaining, or 
inability to obtain, applicable regulatory approvals would prevent us or any of our future development partners from commercializing our product 
candidates. Moreover, we cannot predict healthcare reform initiatives, including potential reductions in federal funding or insurance coverage, that may be 
adopted in the future and whether or not any such reforms would have an adverse effect on our business and our ability to obtain regulatory approval for 
our current or future product candidates. There are evolving legal requirements that will continue to affect our business. 

Because the Company has no experience in commercializing pharmaceutical products, there is a limited amount of information about us upon which 
to evaluate our product candidates and business prospects. 

We have not yet demonstrated an ability to successfully overcome many of the pre-commercial and commercial risks and uncertainties frequently 

encountered by companies in new and rapidly evolving fields, particularly in the biopharmaceutical area. For example, to execute our business plan we will 
need to successfully: 

•

•

•

•

•

•

•

•

•

•

execute our product candidate development activities, including successfully designing and completing our clinical trial programs and 
product design and formulation of future product candidates, in a cost- effective manner; 

file for and obtain required regulatory approvals for our product candidates; 

manage our spending as costs and expenses increase due to the performance and completion of clinical trials, attempting to obtain regulatory 
approvals, manufacturing, and commercialization; 

secure substantial additional funding; 

develop and maintain successful strategic relationships; 

build and maintain a strong intellectual property portfolio; 

build and maintain appropriate clinical, regulatory, quality, manufacturing, compliance, sales, distribution, and marketing capabilities on our 
own or through third parties; 

implement and maintain operational, financial, and management systems;

price our product candidates, if approved, at expected levels and obtain and maintain sufficient insurance and reimbursement from insurers 
and other payors; and 

gain broad market acceptance for our product candidates. 

If we are unsuccessful in accomplishing these objectives, we may not be able to develop product candidates, raise capital, expand our business, or 

continue our operations. Further, even if we are successful in clinical trials of product candidates, we may choose to place further development or 
commercialization on hold given perceived marketing challenges or the relative differences in commercial attractiveness within our portfolio. 

The results of preclinical studies and earlier clinical trials are not always predictive of future results. Any product candidate we or any of our future 
development partners advance into clinical trials, including reproxalap, may not have favorable results in later clinical trials, if any, or receive 
regulatory approval. 

Drug development has inherent risk. We or any of our future development partners will be required to demonstrate through adequate and well-
controlled clinical trials that our product candidates are safe and effective, with a favorable benefit-risk profile, for use in their target indications before we 
can seek regulatory approvals for their commercial sale. Drug development is a long, expensive, and uncertain process, and delay or failure can occur at 
any stage of development, including after commencement of any of our clinical trials. In addition, as product candidates proceed through development, the 
trial designs may often be different and may need to evolve and change from phase to phase or within the same phase or same trial, as is the case for 
adaptive trials; the vehicles or 

48

 
controls may be modified from trial to trial; and the product formulations or manufacturing process may differ due to the need to test product candidate 
samples that can be manufactured on a commercial scale. Success in run-in cohorts, earlier clinical trials, or clinical trials focused on a different indication 
does not mean that later clinical trials will be successful because product candidates in later-stage clinical trials may fail to demonstrate sufficient safety or 
efficacy despite having progressed through other phases of clinical testing. In addition, discussions with regulatory bodies, such as the FDA, may lead to 
changes in trial designs or programs. Companies frequently suffer significant setbacks in advanced clinical trials, even after run-in cohorts or earlier 
clinical trials have shown promising results. For example, the results of the TRANQUILITY Trial did not reflect the results of the TRANQUILITY run-in 
cohort. Moreover, only a small percentage of drugs under development result in the submission of an NDA to the FDA and even fewer are approved for 
commercialization. 

Because we are developing novel product candidates for the treatment of diseases in a manner which there is little clinical drug development 
experience and, in some cases, are designing adaptive trials or using new endpoints or methodologies, the regulatory pathways for approval are not 
well defined, and, as a result, there is greater risk that our clinical trials will not result in our desired outcomes or require additional trials. 

Our clinical focus is on the development of new products for immune-mediated diseases. We are performing an adaptive trial in proliferative 
vitreoretinopathy, the GUARD trial, and may do so with other indications in the future. In an adaptive trial, the initial parts of the trial are not designed to 
be pivotal or definitive. Rather, the initial parts of adaptive trials are expected to provide data to guide subsequent parts of the trial, which could require 
design changes, including but not limited to, different endpoints. In addition, following the initial parts of adaptive trials, we may, among other things, 
decide to continue to the subsequent parts of the trial, conclude the trial based on its success or failure in such initial parts, or discuss the trial results and 
regulatory pathway with regulatory authorities prior to determining next steps with respect to the trial and development program. As such, the likelihood of 
success in our late-stage clinical programs cannot necessarily be predicted. 

We could also face challenges in designing clinical trials and obtaining regulatory approval of our product candidates due to the lack of historical 

clinical trial experience for novel classes of therapeutics. Thus, it is difficult to determine whether regulatory agencies will be receptive to the approval of 
our product candidates, and to predict the time and costs associated with obtaining regulatory approvals. The clinical trial requirements of the FDA and 
other regulatory agencies and the criteria regulators use to determine the safety and efficacy of a product candidate vary substantially according to the type, 
complexity, novelty, and intended use and market of the potential products. The regulatory approval process for novel product candidates such as ours can 
be more expensive and require more time and trial data than for other, better known, or more extensively studied classes of product candidates. In addition, 
it is possible that, as regulatory bodies gain more familiarity with our type of products by reviewing competitor candidates, those agencies could impose 
new conditions on our products that we did not expect. Any inability to design clinical trials with protocols and endpoints acceptable to applicable 
regulatory authorities, and to obtain regulatory approvals for our product candidates, would have an adverse impact on our business, prospects, financial 
condition, and results of operations. 

To preserve trial integrity, clinical data from the initial parts of adaptive clinical trials may not be disclosed.

Adaptive clinical trials are often performed such that the initial parts of the trial are used to determine sample size and endpoints for subsequent, 

possibly pivotal parts of the trial. Results from the initial parts of adaptive trials are therefore not designed to be pivotal or definitive, and, in some cases, 
detailed trial data may not be disclosed so as not to positively or negatively bias investigators or patients involved in subsequent parts of the trial.

We are performing an adaptive trial in proliferative vitreoretinopathy. For the reasons stated above, detailed results from the initial part of the 
GUARD trial may not be disclosed until the completion of subsequent parts of the trials, or until the entire adaptive trial has completed. Further, the initial 
parts of adaptive trials may be performed in part to assess biomarkers or surrogate markers that may require substantial time to generate, analyze, and 
interpret. Thus, disclosure of clinical results from the initial parts of adaptive trials may also be delayed due to the time required for biomarker or surrogate 
marker assessment.

Because some of our product candidates are, to our knowledge, new chemical entities, it is difficult to predict the time and cost of development 

and our ability to successfully complete clinical development of these product candidates and obtain the necessary regulatory approvals for 
commercialization. 

Some of our product candidates are, to our knowledge, new chemical entities, and unexpected problems related to new technologies may arise that 
can cause us to delay, suspend, or terminate our development efforts. As a result, short and long-term safety, as well as prospects for efficacy, are not fully 
understood and are difficult to predict. Regulatory approvals of new product candidates can be more expensive and take longer than approvals for well-
characterized or more extensively studied pharmaceutical product candidates. Following discussions with the FDA and experts in the field, we may 
determine that it is not cost effective for us to develop one or more of our products in certain indications or we may decide to cease development in that 
area or seek a strategic partner.

Because RASP is a new objective sign for the treatment of dry eye disease, there is no precedent in measuring and validating the results of studies of 
RASP in tears, which could impact the timing, cost of development, or interpretation of our trials.

Written meeting minutes with the FDA confirmed the use of RASP as an objective sign for the treatment of dry eye disease. However, to our 
knowledge, a validated assay to measure RASP in tears has not been developed and the FDA has not established guidelines for the design of trials in which 
RASP is measured. There is risk that the RASP assays we have developed will not accurately measure RASP or be accepted by the FDA or other 
regulatory bodies as validated assays.  

Any termination or suspension of, or delays in the commencement or completion of, our clinical trials could result in increased costs to us, delay or 
limit our ability to generate revenue, and adversely affect our commercial prospects. 

Delays in the commencement or completion of our planned clinical trials for reproxalap or other product candidates could significantly affect our 

product development costs and timeline. We do not know whether future trials will begin on time or be completed on schedule, if at all. The 
commencement and completion of clinical trials can be delayed for a number of reasons, including delays related to: 

•

•

•

•

•

•

•

•

•

•

the COVID-19 pandemic or responses thereto;

the FDA, or an institutional review board, or IRB, failing to grant permission to proceed or placing a clinical trial on hold; 

subjects failing to enroll or remain in our clinical trials at the rate we expect; 

subjects choosing an alternative treatment for the indication for which we are developing reproxalap or other product candidates, or 
participating in competing clinical trials; 

lack of adequate funding to continue the clinical trial; 

subjects experiencing severe, serious, or unexpected drug-related adverse effects, whether drug-related or otherwise; 

a facility manufacturing reproxalap, our other product candidates, or drug product components being ordered by the FDA or other 
government or regulatory authorities to temporarily or permanently shut down due to violations of cGMP or other applicable requirements, or 
infections or cross-contaminations of product candidates in the manufacturing process; 

any changes to our manufacturing process that may be necessary or desired; 

inability to timely manufacture sufficient quantities of the applicable product candidate for a clinical trial or expiration of materials intended 
for use in a clinical trial; 

third-party clinical investigators losing the licenses or permits necessary to perform our clinical trials, not performing our clinical trials on 
our anticipated schedule or consistent with the clinical trial protocol, cGMP, or regulatory requirements, or other third parties not performing 
data collection or analysis in a timely or accurate manner; 

50

 
•

•

•

•

inspections of clinical trial sites by the FDA or the finding of regulatory violations by the FDA or IRB, that require us or others to undertake 
corrective action, result in suspension or termination of one or more sites or the imposition of a clinical hold in part or on the entire trial, or 
that prohibit us from using some or all of the data in support of our marketing applications; 

delays in shipment of clinical trial material reaching clinical sites;

third-party contractors becoming debarred or suspended or otherwise penalized by the FDA or other government or regulatory authorities for 
violations of regulatory requirements, in which case we may need to find a substitute contractor, and we may not be able to use some or all of 
the data produced by such contractors in support of our marketing applications; or 

one or more IRBs refusing to approve, suspending, or terminating the trial at an investigational site; precluding enrollment of additional 
subjects; or withdrawing its approval of the trial. 

Product development costs will increase if we have delays in testing or approval of reproxalap or our other product candidates or if we need to 
perform more, larger, or longer clinical trials than planned. Additionally, changes in regulatory requirements and policies may occur and we or our partners 
may need to amend clinical trial protocols to reflect these changes. Amendments may require us to resubmit our clinical trial protocols to IRBs for 
reexamination, which may impact the costs, timing, or successful completion of a clinical trial. If we experience delays in completion of, or if we, the FDA, 
or other regulatory authorities, the IRB, other reviewing entities, or any of our clinical trial sites suspend or terminate any of our clinical trials, the 
commercial prospects for a product candidate may be harmed and our ability to generate product revenues, if any, will be delayed. In addition, many of the 
factors that cause, or lead to, termination or suspension of, or a delay in the commencement or completion of, clinical trials may also ultimately lead to the 
denial of regulatory approval of a product candidate. Further, if one or more clinical trials are delayed, our competitors may be able to bring products to 
market before we do, and the commercial viability of reproxalap or other product candidates could be significantly reduced. 

We may find it difficult to enroll patients in our clinical trials or identify patients during commercialization (if our products are approved by regulatory 
agencies) for product candidates addressing orphan or rare diseases. 

As part of our business strategy, we have and continue to evaluate the development and commercialization of product candidates for the treatment of 
orphan and other rare diseases, including PVR and retinitis pigmentosa. We may not be able to initiate or continue clinical trials if we are unable to locate a 
sufficient number of eligible patients willing and able to participate in the clinical trials required by the FDA or other non-United States regulatory 
agencies. In addition, if others develop products for the treatment of similar diseases, we would potentially compete with them for the enrollment in rare 
patient populations, which may adversely impact the rate of patient enrollment in and the timely completion of our current and planned clinical trials. Any 
negative results or perceived negative results in clinical trials of our product candidates may make it difficult or impossible to recruit or retain patients in 
other clinical trials of the same product candidate. Insufficient patient enrollment may be a function of other factors, including the size and nature of the 
patient population, the nature of the protocol, the proximity of patients to clinical sites, the timing and magnitude of disease symptom presentation, the 
availability of effective treatments for the relevant disease, and the eligibility criteria for the clinical trial. Our inability to identify and enroll a sufficient 
number of eligible patients for any of our current or future clinical trials would result in significant delays or may require us to abandon one or more 
clinical trials or development program. The ongoing COVID-19 pandemic has and is expected to continue to have an impact on our ability to enroll and 
retain patients in our clinical trials. For instance, patient enrollment in our GUARD trial was negatively impacted as a result of limited clinical trial staffing 
at study sites and some patients electing to delay surgery. Delays in patient enrollment in the future as a result of these and other factors may result in 
increased costs or may affect the timing or outcome of our clinical trials, which could prevent us from completing these trials and adversely affect our 
ability to advance the development of our product candidates. For instance, in rare diseases such as PVR, lack of availability of, or difficulty recruiting or 
retaining a sufficient number of, patients may make it difficult or cost-prohibitive to sufficiently power our clinical trials, which may not enable us to 
continue development and seek regulatory approval for the applicable product candidate. Further, if our products are approved by regulatory agencies, we 
may not be able to identify sufficient number of patients to generate significant revenues. 

51

 
Any product candidate we or any of our future development partners advance into clinical trials may cause unacceptable adverse events or have other 
properties that may delay or prevent its regulatory approval or commercialization or limit its commercial potential. 

Unacceptable adverse events caused by any of our product candidates that we or others advance into clinical trials could cause us or regulatory 

authorities to interrupt, delay, or halt clinical trials, or impose a clinical hold, potentially resulting in the denial of regulatory approval by the FDA or other 
regulatory authorities for any or all targeted indications and markets. This in turn could prevent us from completing development or commercializing the 
affected product candidate and generating revenue from its sale. 

We have not yet completed testing of any of our product candidates in humans for the treatment of the indications for which we intend to seek 
approval, and we currently do not know the full extent of adverse events that will be observed in subjects that receive any of our product candidates. If any 
of our product candidates cause unacceptable adverse events in clinical trials, which may be larger or longer than those previously conducted, we may not 
be able to obtain regulatory approval or commercialize such product candidate. 

Final marketing approval for reproxalap or our other product candidates by the FDA or other regulatory authorities may be delayed, limited, or denied, 
any of which would adversely affect our ability to generate operating revenues. 

After the completion of our clinical trials, assuming the results of the trials are successful, and the submission of an NDA, we cannot predict 

whether or when we will obtain regulatory approval to commercialize reproxalap or our other product candidates and we cannot, therefore, predict the 
timing of any future revenue. We cannot commercialize reproxalap or our other product candidates until the appropriate regulatory authorities have 
reviewed and approved the applicable applications. We cannot assure you that the regulatory agencies will complete their review processes in a timely 
manner or that we will obtain regulatory approval for reproxalap or our other product candidates. In addition, we may experience delays or rejections based 
upon additional government regulation from future legislation or administrative action or changes in FDA policy or leadership during the period of product 
development, clinical trials, and FDA regulatory review. If marketing approval for reproxalap or our other product candidates is delayed, limited or denied, 
our ability to market the product candidate, and our ability to generate product sales, would be adversely affected. Such a delay could occur because a 
competitor product is approved before our product and secures patent protection, market exclusivity, or both, and thereby precludes our product approval 
for a number of years.

Even if we obtain marketing approval for reproxalap or any other product candidate, it could be subject to restrictions or withdrawal from the market 
and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with our product 
candidates, when and if any are approved. 

Even if United States regulatory approval is obtained, the FDA may still impose significant restrictions on a product’s indicated uses or marketing or 

impose ongoing requirements for potentially costly and time-consuming post-approval studies, post-market surveillance, or other potential additional 
clinical trials. Following approval, if any, of reproxalap or any other product candidate, such candidate will also be subject to ongoing FDA requirements 
governing the labeling, packaging, storage, distribution, safety surveillance, advertising, promotion, recordkeeping, and reporting of safety and other post-
market information. In addition, manufacturers of drug products and their facilities are subject to continual review and periodic inspections by the FDA and 
other regulatory authorities for compliance with cGMP requirements, including those relating to quality control, quality assurance, and corresponding 
maintenance of records and documents. If we or a regulatory agency discovers previously unknown problems with a product, such as adverse events of 
unanticipated seriousness, severity, or frequency, or problems with the facility where the product is manufactured, a regulatory agency may impose 
restrictions on that product, the manufacturing facility or us, including requesting recall or withdrawal of the product from the market or suspension of 
manufacturing. 

52

 
If we or the manufacturing facilities for reproxalap or any other product candidate that may receive regulatory approval, if any, fail to comply with 

applicable regulatory requirements, a regulatory agency may: 

•

•

•

•

•

•

•

issue warning letters or untitled letters; 

seek an injunction or impose civil or criminal penalties or monetary fines; 

suspend or withdraw regulatory approval; 

suspend any ongoing clinical trials; 

refuse to approve pending applications or supplements or applications filed by us; 

suspend or impose restrictions on operations, including costly new manufacturing requirements; or 

seize or detain products, refuse to permit the import or export of product, or request us to initiate a product recall. 

The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenue. 

The FDA has the authority to require a risk evaluation and mitigation strategy (REMS) plan as part of an NDA or after approval, which may impose 
further requirements or restrictions on the distribution or use of an approved drug, such as limiting prescribing to certain physicians or medical centers that 
have undergone specialized training, limiting treatment to patients who meet certain safe-use criteria, and requiring treated patients to enroll in a registry. 

In addition, if reproxalap or any of our other product candidates is approved, our product labeling, advertising, and promotion would be subject to 

regulatory requirements and continuing regulatory review. The FDA strictly regulates the promotional claims that may be made about prescription 
products. In particular, a product may not be promoted for uses that are not approved by the FDA as reflected in the product’s approved labeling. If we 
receive marketing approval for a product candidate, physicians may nevertheless prescribe it to patients in a manner that is inconsistent with the approved 
label. If we are found to have promoted such off-label uses, we may become subject to significant liability. The FDA and other agencies actively enforce 
the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be 
subject to significant sanctions. The federal government has levied large civil and criminal fines against companies for alleged improper promotion and has 
enjoined several companies from engaging in off-label promotion. The government has also entered into consent decrees and Corporate Integrity 
Agreements under which specified promotional conduct is changed or curtailed. 

Even if we receive regulatory approval for reproxalap or any other product candidate, we still may not be able to successfully commercialize, and the 
revenue that we generate from its sales, if any, could be limited. 

Even if our product candidates receive regulatory approval, they may not gain market acceptance among physicians, patients, healthcare payors, or 

the medical community. Coverage and reimbursement of our product candidates by third-party payors, including government payors, is also generally 
necessary for commercial success. In addition, we may not be able to secure advantageous contracts with payors or price our products at the expected level 
or at levels that make successful commercialization viable. The pricing of our products will be subject to numerous factors, many of which are outside of 
our control, including the pricing of similar products. The degree of market acceptance of our product candidates will depend on a number of factors, 
including but not limited to: 

•

•

•

•

•

demonstration of clinical efficacy and safety compared to other more-established products; 

the limitation of our targeted patient populations and other limitations or warnings contained in any FDA-approved labeling; 

acceptance of a new formulations by health care providers and their patients; 

the prevalence, seriousness, and severity of any adverse effects; 

new procedures or methods of treatment that may be more effective in treating conditions for which our products are intended to treat; 

53

 
•

•

•

•

•

•

•

•

•

the safety of product candidates seen in a broader patient group, including their use outside the approved indications;

pricing and cost-effectiveness, including the cost of treatment in relation to alternative treatments; 

the effectiveness of our or any future collaborators’ sales and marketing strategies; 

our ability to obtain and maintain sufficient, commercially advantageous, and timely third-party coverage or reimbursement from government 
health care programs, including Medicare and Medicaid, private health insurers and other third-party payors; 

relative convenience and ease of administration; 

the prevalence and severity of adverse events; 

the effectiveness of our sales and marketing efforts;

unfavorable publicity; and 

the willingness of patients to pay out-of-pocket in the absence of third-party coverage. 

In addition, because the active ingredient of ADX-2191 (methotrexate) is a generic drug, a generic manufacturer may be able to develop and market 

a competitive intravitreal formulation of methotrexate following expiration of commercial exclusivity mandated via certain orphan drug designations. 
Generic drug competition would have a material and adverse effect on the commercial potential of ADX-2191.  Further, our ability to successfully 
commercialize ADX-2191, if approved, depends on a number of additional factors, including but not limited to, the level of enforcement by the FDA to 
ensure that compounded copies of commercially available FDA-approved products manufactured by compounding pharmacies, including compounded 
copies of ADX-2191, that may be in violation of the federal Drug Quality and Security Act (DQSA) and other relevant provisions of the United States 
Federal Food, Drug, and Cosmetic Act (FDCA), are not produced and dispensed to patients.

Moreover, we cannot predict what healthcare reform initiatives may be adopted in the future. Further federal and state legislative and regulatory 
developments are likely, and we expect that ongoing initiatives in the United States will increase pressure on drug pricing. Such reforms could have an 
adverse effect on the pricing of and anticipated revenues from our current or future product candidates for which we may obtain regulatory approval and 
may affect our overall financial condition and ability to develop drug candidates. 

If any product candidate is approved but does not achieve an adequate level of acceptance by physicians, hospitals, healthcare payors, or patients, 

we may not generate sufficient revenue from that product candidate and may not become or remain profitable. Our efforts to educate the medical 
community and third-party payors on the benefits of reproxalap or any of our other product candidates may require significant resources and may never be 
successful. In addition, our ability to successfully commercialize our product candidate will depend on our ability to manufacture our products, differentiate 
our products from competing products and defend the intellectual property of our products. Competitors with numerous approved products may be able to 
negotiate pricing and reimbursement that is substantially more advantageous than that which we will be able to negotiate.

Additionally, if any of our competitors’ products are approved and are unable to gain market acceptance for any reason, there could be a market 

perception that products like reproxalap are not able to adequately meet an unmet medical need. If we are unable to demonstrate to physicians, hospitals, 
third-party payors, and patients that our products are better alternatives, we may not be able to gain market acceptance for our products at the levels we 
anticipate and our business may be materially harmed as a result. 

If the market opportunities for reproxalap and our other product candidates are smaller than we believe they are and, if we are not able to successfully 
identify patients and achieve significant market share, our revenues may be adversely affected and our business may suffer.

We focus our research and product development on treatments for immune-mediated diseases. Our estimated addressable markets and market 
opportunities for our drug candidates are based on a variety of inputs, including data published by third parties, our own market insights and internal 
market intelligence, and internally generated 

54

 
data and assumptions. We have not independently verified any third-party information and cannot be assured of its accuracy or completeness. Our 
projections of both the number of people who have these diseases, as well as the subset of people with these diseases who have the potential to benefit from 
treatment with our product candidates, are based on estimates. These estimates have been derived from a variety of sources, including scientific literature, 
surveys of clinics, or market research, and may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of these 
diseases. The number of patients may turn out to be lower or more difficult to identify than expected. In addition, our product candidates may not achieve 
commercial success due to market conditions or regulatory challenges.

Any of these factors may negatively affect our ability to generate revenues from sales of our product and our ability to achieve and maintain 
profitability, and as a consequence, our business may suffer. In addition, these inaccuracies or errors may cause us to misallocate capital and other critical 
business resources, which could harm our business.

Reimbursement may be limited or unavailable in certain market segments for our product candidates, which could make it difficult for us to sell our 
product candidates profitably. 

Market acceptance and sales of our product candidates will depend significantly on the availability of adequate insurance coverage and 

reimbursement from third-party payors for any of our product candidates and may be affected by existing and future health care reform measures. 
Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which drugs they will pay for 
and establish reimbursement levels. The reimbursement levels may be significantly less than the currently anticipated pricing of our product candidates. As 
a result of negative trends in the general economy in the United States or other jurisdictions in which we may do business, these organizations may be 
unable to satisfy their reimbursement obligations or may delay payment. Reimbursement by a third-party payor may depend upon a number of factors 
including the third-party payor’s determination that use of a product candidate is: 

•

•

•

•

•

a covered benefit under its health plan; 

safe, effective, and medically necessary; 

appropriate for the specific patient; 

cost-effective, including cost effectiveness relative to existing contracts with other pharmaceutical companies; and 

neither experimental nor investigational. 

55

 
Obtaining coverage and reimbursement approval for a product candidate from a government or other third-party payor is a time-consuming and 

costly process that could require us to provide supporting scientific, clinical, and cost effectiveness data for the use of the applicable product candidate to 
the payor. We may not be able to provide data sufficient to gain acceptance with respect to coverage and reimbursement. We cannot be sure that coverage 
or adequate reimbursement will be available for any of our product candidates. Further, we cannot be sure that reimbursement amounts will not reduce the 
demand for, or the price of, our product candidates. If reimbursement is not available or is available only in limited levels, we may not be able to 
commercialize certain of our product candidates profitably, or at all, even if approved. In recent years, through legislative and regulatory actions, the 
federal government has made substantial changes to the United States healthcare system, including changes to the methods for, and amounts of, Medicare 
reimbursement. Many members of the United States Congress have attempted to repeal and replace the Patient Protection and Affordable Care Act 
(PPACA), but they have been unsuccessful in doing so as of the date of the filing of this report. We cannot predict the ultimate form or timing of any repeal 
or replacement of PPACA or the effect such repeal or replacement would have on our business. Regardless of the impact of repeal or replacement of 
PPACA on us, the government has shown significant interest in pursuing healthcare reform and reducing healthcare costs. These reforms could 
significantly reduce payments from Medicare and Medicaid over the next ten years. Reforms or other changes to these payment systems, including 
modifications to the conditions on qualification for payment, bundling of payments, or the imposition of enrollment limitations on new providers, may 
change the availability, methods, and rates of reimbursements from Medicare, private insurers, and other third-party payers for our current and future 
product candidates, if any, for which we are able to obtain regulatory approval. Some of these changes and proposed changes could result in reduced 
reimbursement rates for such product candidates, if approved, which would adversely affect our business strategy, operations, and financial results. 

As a result of legislative proposals and the trend toward managed health care in the United States, third-party payors are increasingly attempting to 
contain health care costs by limiting both coverage and the level of reimbursement of new drugs. Payors may also refuse to provide coverage of approved 
product candidates for medical indications other than those for which the FDA has granted market approvals. As a result, significant uncertainty exists as to 
whether and how much third-party payors will reimburse patients for use of newly approved drugs, which in turn could lower drug pricing. We expect to 
experience pricing pressures in connection with the sale of our product candidates due to the trend toward managed health care, the increasing influence of 
health maintenance organizations, larger companies contracting with payors to diminish reimbursement for competitive products, and additional legislative 
proposals as well as country, regional, or local healthcare budget limitations. 

If we fail to develop and commercialize other product candidates, we may be unable to grow our business. 

As part of our growth strategy, we plan to evaluate the development and commercialization of other therapies related to immune-mediated diseases. 
We will evaluate internal opportunities from our compound libraries, and also may choose to continue to in-license or acquire other product candidates, as 
well as commercial products, to treat patients suffering from immune-mediated disorders with high unmet medical needs and limited treatment options. 
These other product candidates will require additional, time-consuming development efforts prior to commercial sale, including preclinical studies, clinical 
trials, and approval by the FDA and/or applicable foreign regulatory authorities. In-licensed product candidates may have been unsuccessfully developed 
by others in indications similar to those that we may pursue. All product candidates are prone to the risks of failure that are inherent in pharmaceutical 
product development, including the possibility that the product candidate will not be shown to be sufficiently safe and/or effective for approval by 
regulatory authorities. In addition, we cannot assure you that any such products that are approved will be manufactured or produced economically, 
adequately priced, successfully commercialized, or widely accepted in the marketplace or be more effective than other commercially available alternatives. 
56

 
We may not be able to qualify for or obtain various designations from regulators that would have the potential to expedite the review process of one or 
more of our product candidates, and even if we do receive one or more of such designations there is no guarantee that they will ultimately expedite the 
process, or aid in our obtaining marketing approval or provide market exclusivity. 

There exist several designations that we can apply for from the FDA and other regulators that would provide us with various combinations of the 

potential for expedited regulatory review, certain financial incentives as well as the potential for post-approval exclusivity for a period of time. These 
designations include but are not limited to orphan drug designation, breakthrough therapy designation, accelerated approval, fast track status, and priority 
review for our product candidates. We may seek one or more of these designations for our current and future product candidates. There can be no assurance 
that any of our other product candidates will qualify for any of these designations. There can also be no assurance that any of our product candidates, that 
do qualify for these designations, will be granted such designations or that the FDA will not revoke such a designation it grants at a later date. Further, there 
can be no assurance that any of our product candidates that are granted such designations will ever benefit from such designations or that the FDA would 
not withdraw such designations once granted. Were we to receive a designation that promised a period of market exclusivity, such as orphan drug 
exclusivity, such exclusivity may not effectively protect the product from competition because different drugs can be approved for the same condition. 
Further, with respect to orphan drug status, even after an orphan drug is approved, the FDA can subsequently approve the same drug for the same condition 
if the FDA concludes that the later drug is clinically superior if it is shown to be safer, more effective, or makes a major contribution to patient care.

We are subject to a multitude of manufacturing risks, any of which could substantially increase our costs and limit supply of our products. 

The process of manufacturing our products is complex, highly regulated, and subject to several risks, including: 

•

•

•

The manufacturing of compounds is extremely susceptible to product loss due to contamination, equipment failure, improper installation or 
operation of equipment, or vendor or operator error. Even minor deviations from normal manufacturing processes could result in reduced 
production yields, product defects, and other supply disruptions. If microbial, viral, or other contaminations are discovered in our products or 
in the manufacturing facilities in which our products are made, such manufacturing facilities may need to be closed for an extended period of 
time to investigate and remedy the contamination. 

The manufacturing facilities in which our products are made could be adversely affected by equipment failures, labor shortages, natural 
disasters, power failures, and numerous other factors. 

We and our contract manufacturers must comply with the cGMP regulations and guidelines. We and our contract manufacturers may 
encounter difficulties in achieving quality control and quality assurance, and may experience shortages in qualified personnel. We and our 
contract manufacturers are subject to inspections by the FDA and comparable agencies in other jurisdictions to confirm compliance with 
applicable regulatory requirements. Any failure to follow cGMP or other regulatory requirements or any delay, interruption, or other issues 
that arise in the manufacture, fill-finish, packaging, or storage of our products as a result of a failure of our facilities or the facilities or 
operations of third parties to comply with regulatory requirements or pass any regulatory authority inspection could significantly impair our 
ability to develop and commercialize our products, including leading to significant delays in the availability of products for our clinical 
studies, the termination or hold on a clinical study, or the delay or prevention of a filing or approval of marketing applications for our product 
candidates. Significant noncompliance could also result in the imposition of sanctions, including fines, injunctions, civil penalties, failure of 
regulatory authorities to grant marketing approvals for our product candidates, delays, suspension or withdrawal of approvals, license 
revocation, seizures or recalls of products, operating restrictions, and criminal prosecutions, any of which could damage our reputation or 
impair our ability to develop and commercialize our products. If we are not able to maintain regulatory compliance, we may not be permitted 
to market our products and/or may be subject to product recalls, seizures, injunctions, or criminal prosecution. 

57

 
In order to conduct clinical trials of our drug candidates, we will need to manufacture them in large quantities. Quality issues may arise during scale-
up activities. Our reliance on a limited number of Contract Manufacturing Organizations (CMOs), the complexity of drug manufacturing and the difficulty 
of scaling up a manufacturing process could cause the delay of clinical trials, regulatory submissions, required approvals or commercialization of our drug 
candidates, and cause us to incur higher costs and prevent us from commercializing our drug candidates successfully. Furthermore, if our CMOs fail to 
deliver the required commercial quality and quantities of materials on a timely basis and at commercially reasonable prices, and we are unable to secure 
one or more replacement CMOs capable of production in a timely manner at a substantially equivalent cost, then testing and clinical trials of that drug 
candidate may be delayed or infeasible, and regulatory approval or commercial launch of any resulting product may be delayed or not obtained, which 
could significantly harm our business. In addition, failure of CMOs to comply with regulatory and quality requirements could delay manufacturing or the 
review of our marketing applications.

Any adverse developments affecting manufacturing operations for our products, including as a result of the COVID-19 pandemic or responses taken 
thereto, may result in shipment delays; inventory shortages; lot failures; product withdrawals, recalls, approvals; or other interruptions in the supply of our 
products. We may also have to account for inventory write-offs and incur other charges and expenses for products that fail to meet specifications, undertake 
costly remediation efforts, or seek more costly manufacturing alternatives. 

If our competitors develop treatments for the target indications of our product candidates that are approved more quickly than ours, marketed more 
successfully, or demonstrated to be safer or more effective than our product candidates, our commercial opportunity will be reduced or eliminated. 

We operate in highly competitive segments of the biotechnology market. We face competition from many different sources, including commercial 

pharmaceutical and biotechnology enterprises, academic institutions, government agencies, and private and public research institutions. Our product 
candidates, if successfully developed and approved, will compete with established therapies (including generic and over-the-counter drugs) as well as with 
new treatments that may be introduced by our competitors. With the exception of PVR, PVRL, and retinitis pigmentosa, there are a variety of approved 
drugs and drug candidates in development for the indications that we intend to test. Current treatments that are used in the United States for dry eye disease 
include over the counter artificial tears, Restasis®, Xiidra®, CequaTM, Eysuvis®,  and TyrvayaTM .  In February 2022, the FDA approved the first generic 
versions of Restasis®, which is expected to become available in the U.S. in the near future. Many of our competitors have significantly greater financial, 
product candidate development, manufacturing, and marketing resources than we do. Large pharmaceutical and biotechnology companies have extensive 
experience in clinical testing and obtaining regulatory approval for drugs. In addition, universities and private and public research institutes could be in 
direct competition with us. We also may compete with these organizations to recruit management, scientists, and clinical development personnel. We will 
also face competition from these third parties in establishing clinical trial sites, registering subjects for clinical trials, and in identifying and in-licensing 
new product candidates. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements 
with large and established companies. 

New developments, including the development of other pharmaceutical technologies and methods of treating disease, occur in the pharmaceutical 

and life sciences industries at a rapid pace. Developments by competitors may render our product candidates obsolete or noncompetitive. Other parties may 
discover and patent treatment approaches and compositions that are similar to or different from ours. Competition in drug development is intense. We 
anticipate that we will face intense and increasing competition as new treatments enter the market and advanced technologies become available. 

Our future success depends on our ability to demonstrate and maintain a competitive advantage with respect to the design, development, and 
commercialization of reproxalap or our other product candidates. Inflammatory diseases may be treated with general immune suppressing therapies, 
including corticosteroids, some of which are generic. Our potential competitors in inflammatory diseases may be developing novel immune modulating 
therapies that may be safer or more effective than our product candidates.

If we are unable to establish and maintain sales, distribution, and marketing capabilities or enter into agreements with third parties to market, 

sell, and distribute our product candidates, we may be unable to generate any revenues.

We have no sales or marketing infrastructure and have no experience as a Company in the sale, marketing or distribution of biopharmaceutical 

products. If reproxalap or any of our other product candidates ultimately receives regulatory approval, we may not be able to effectively market and 
distribute the product candidate. We will have to invest significant amounts of financial and management resources to develop and maintain internal sales, 
distribution, and marketing capabilities, some of which will be committed prior to any confirmation that reproxalap or any of our other product candidates 
will be approved. 

We currently expect that we may build our own sales and marketing organization to support the commercialization in the United States of product 

candidates for which we receive marketing approval. There are risks involved with establishing our own sales and marketing capabilities. For example, 
recruiting and training a sales force is expensive and time-consuming and could delay any product launch. If the commercial launch of a product candidate 
for which we recruit a sales force and establish marketing capabilities is delayed or does not occur for any reason, we would have incurred these 
commercialization expenses prematurely or unnecessarily. These efforts may be costly, and our investment would be lost if we cannot retain or reposition 
our sales and marketing personnel.

If we are unable to establish our own sales and marketing capabilities and enter into arrangements with third parties to perform these services, our 

revenue from product sales and our profitability, if any, are likely to be lower than if we ourselves were to market and sell any products that we develop. In 
addition, we may not be successful in entering into arrangements with third parties to market and sell our drug candidates or may be unable to do so on 
terms that are acceptable to us. Any of these third parties may fail to devote the necessary resources and attention to sell and market our products 
effectively. If we do not establish sales and marketing capabilities successfully, either on our own or in collaboration with third parties, we will not be 
successful in commercializing our drug candidates.

Current and future legislation may increase the difficulty and cost for us to obtain regulatory and marketing approval of and commercialize our 
product candidates, and may affect the prices we may obtain. 

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding 

healthcare systems that could prevent or delay marketing approval for our product candidates, restrict or regulate post-approval activities, and affect our 
ability to profitably sell any product candidates for which we obtain marketing approval. The pharmaceutical industry has been a particular focus of these 
efforts and has been significantly affected by legislative initiatives. Current laws, as well as other healthcare reform measures that may be adopted in the 
future, may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any FDA approved product.

Healthcare reform measures that may be adopted in the future, may result in reductions in Medicare and other healthcare funding, more rigorous 

coverage criteria, new payment methodologies, and additional downward pressure on the price that we receive for any approved product and/or the level of 
reimbursement physicians receive for administering any approved product we might bring to market. Reductions in reimbursement levels may negatively 
impact the prices we receive or the frequency with which our products are prescribed or administered. Any reduction in reimbursement from Medicare or 
other government programs may result in a similar reduction in payments from private payors.

To date, there have been several recent U.S. congressional inquiries and proposed and enacted state and federal legislation and regulation designed 

to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient support programs, 
reduce the costs of drugs under Medicare, and reform government program reimbursement methodologies for drug products. For example, included in the 
Consolidated Appropriations Act, 2021 were several drug price reporting and transparency measures, such as a new requirement for certain Medicare plans 
to develop tools to display Medicare Part D prescription drug benefit information in real time and for group and health insurance issuers to report 
information on pharmacy benefit and drug costs to the Secretaries of the Department of Health and Human Services, the Department of Labor, and the 
Treasury. Additionally, both Congress and the Biden administration have each indicated willingness to continue to 

59

 
seek new legislative and/or administrative measures to address prescription drug costs. For example, on July 9, 2021, President Biden issued an Executive 
Order to promote competition in the U.S. economy that included several initiatives addressing prescription drugs. Among other provisions, the Executive 
Order stated that the Biden administration will “support aggressive legislative reforms that would lower prescription drug prices, including by allowing 
Medicare to negotiate drug prices, by imposing inflation caps, and through other related reforms.” In response to the Executive Order, on September 9, 
2021, the Department of Health and Human Services issued a Comprehensive Plan for Addressing High Drug Prices that identified potential legislative 
policies and administrative tools that Congress and the agency can pursue in order to make drug prices more affordable and equitable, improve and promote 
competition throughout the prescription drug industry, and foster scientific innovation. Congress has also continued to conduct inquiries into the 
prescription drug industry’s pricing practices.

At the state level, individual states are increasingly aggressive in passing legislation and implementing regulations designed to control 

pharmaceutical and biological product pricing. These include legislation and regulations regarding price or patient reimbursement constraints, discounts, 
restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, legislative action designed to encourage 
importation from other countries and bulk purchasing. In addition, regional health care authorities and individual hospitals are increasingly using bidding 
procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other health care programs. 
These measures could reduce the ultimate demand for our products, if approved, or put pressure on our product pricing.

Legislative and regulatory proposals have also been made to expand post-approval requirements and restrict sales and promotional activities for 

pharmaceutical products. We cannot be sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance, or 
interpretations will be changed, or what the impact of such changes on the potential approval and marketing approvals of our drug candidates, if any, may 
be. Increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay or prevent marketing approval, as well as subject us to 
more stringent product labeling and post-marketing testing and other requirements.

The continuing efforts of the government, insurance companies, managed care organizations, and other payors of healthcare services to contain or 

reduce costs of health care may adversely affect: 

•

•

•

•

•

•

the demand for any product candidates for which we may obtain regulatory approval; 

our ability to set a price that we believe is fair for our product candidates; 

our ability to generate revenue and achieve or maintain profitability; 

our ability to identify and establish strategic partnerships;

the level of taxes that we are required to pay;

the availability of capital. 

If the FDA or comparable foreign regulatory authorities approve generic versions of any of our product candidates that receive marketing 

approval, or such authorities do not grant our product candidates appropriate periods of data or market exclusivity before approving generic versions 
of our product candidates, the sales of our product candidates could be adversely affected.

Once an NDA is approved, the drug covered thereby becomes a “reference-listed drug” in the FDA’s publication, “Approved Drug Products with 
Therapeutic Equivalence Evaluations.” Manufacturers may seek marketing approval of generic versions of reference-listed drugs through submission of 
abbreviated new drug applications (ANDAs) in the United States. In support of an ANDA, a generic manufacturer need not conduct clinical trials 
demonstrating safety and efficacy. Rather, the applicant generally must show that its drug is pharmaceutically equivalent to the reference listed drug, in that 
it has the same active ingredient(s), dosage form, strength, route of administration and conditions of use or labeling as the reference-listed drug, and that the 
generic version is bioequivalent to the reference-listed drug, meaning it is absorbed in the body at the same rate and to the same extent. Generic drugs may 
be significantly less costly to bring to market than the reference-listed drug and companies that produce generic drugs are generally able to offer drug 
products at lower prices. Thus, following the 

60

 
introduction of a generic drug, a significant percentage of the sales of any branded product or reference-listed drug is typically lost to the generic drug.

The FDA may not approve an ANDA for a generic drug until any applicable period of non-patent exclusivity for the reference-listed drug has 
expired. The FDCA provides a period of five years of non-patent exclusivity for a new drug containing a new chemical entity. During the exclusivity 
period, the FDA may not accept for review an ANDA or a 505(b)(2) NDA submitted by another company for another version of such product candidate 
where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after 
four years if it contains a certification of patent invalidity, enforceability or non-infringement. The FDCA also provides three years of marketing exclusivity 
for a 505(b)(1) NDA, 505(b)(2) NDA or supplement to an approved NDA if new clinical investigations other than bioavailability studies (e.g., 
investigations that support new indications, dosages, or strengths of an existing drug) were conducted or sponsored by the applicant and are deemed by the 
FDA to be essential to the approval of the application. This three-year exclusivity covers only the conditions associated with the new clinical investigations 
and does not prohibit the FDA from approving competitor products for product candidates containing the original active agent for other conditions of use. 
Five-year and three-year exclusivity will not delay the submission or approval of a full 505(b)(1) NDA. Manufacturers may seek to launch these generic 
drugs following the expiration of the marketing exclusivity period, even if we still have patent protection for our drug.

In the EU and the UK, innovative medicinal products are authorized based on a full marketing authorization application (as opposed to an 
application for marketing authorization that relies on data in the marketing authorization dossier for another, previously approved medicinal product). 
Applications for marketing authorization for innovative medicinal products must contain the results of pharmaceutical tests, preclinical tests, and clinical 
trials conducted with the medicinal product for which marketing authorization is sought (and where applicable the result of the pediatric studies unless a 
waiver or a deferral has been obtained - as described further below). In the EU, these applications must be made pursuant to either Directive 2001/83/EC 
(for the decentralized procedure or the mutual recognition procedure) or Regulation 726/2004 (for the centralized procedure). In the UK, there are various 
procedures available under the new regulatory legal framework to pharmaceutical products, including the possibility of a recognized assessment conducted 
by the European authorities under certain circumstance or by applying directly to the UK regulatory authority (MHRA).

Where an applicant for a marketing authorization submits a full dossier containing its own pharmaceutical, pre-clinical tests and clinical trials data, 
and where the application does not fall within the "global marketing authorization" of an existing medicinal product, the applicant is entitled to eight years 
of regulatory data protection upon grant of the marketing authorization (the period starts to run from the first marketing authorization in the EU/ European 
Economic Area [EEA]). During this period, applicants for approval of generics or biosimilars cannot rely on data contained in the marketing authorization 
dossier submitted for the already authorized, or reference, medicinal product to support their application. After the expiration of the eight-year period of 
regulatory data protection, the reference medicinal product benefits from a further two-year period of marketing protection. During these two years of 
marketing protection, no generic or biosimilar medicinal product that relies upon the reference medicinal product’s dossier may be placed on the EU 
market, but a generic or biosimilar marketing authorization application can be submitted to the competent regulatory authorities in the EU Member States 
during this time. The two-year period of marketing protection can further be extended by one year if, during the first eight years of the grant of the first 
marketing authorization, the marketing authorization holder obtains an authorization for one or more new therapeutic indications which, during the 
scientific evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies. However, even if a 
compound is considered to be a new active substance and the innovator is able to gain the period of regulatory data protection and marketing protection, 
provided that no other IP or regulatory exclusivities applied, another unrelated company could also apply for a marketing authorization and market another 
competing medicinal product for the same therapeutic indication if such company obtained its own marketing authorization based on a separate marketing 
authorization application based on a full self-standing scientific data package supporting the application. The period of regulatory data protection and 
marketing protection applies in the UK (running from the date of the first authorization in Great Britain).

In the EU, pursuant to Regulation 1901/2006, and in the UK pursuant to the Human Medicines Regulations 2012 (as amended), marketing 

authorization applications must include pediatric data based on pediatric investigation 

61

 
plans agreed with the EMA if the MAA concerns (i) a new active substance, or (ii) a new indication, pharmacological form, or route of administration 
(where the product is protected by a supplementary protection certificate or a patent qualifying for a supplementary certificate). Applicants may obtain 
waivers or deferrals to these requirements in certain circumstances (for example a waiver may be obtained if the condition only occurs in adult 
populations). Where required, pediatric studies must cover all sub-sets of the pediatric population for both existing and new indications, pharmacological 
forms and route of administrations. Limited further exclusions apply, including in relation to generic or biosimilar applications. Certain rewards may be 
available for completion of pediatric studies. For example, where MAAs include the results of all studies conducted in compliance with an agreed pediatric 
investigation plan, the holder of the patent or supplementary protection certificate may be entitled to a six-month extension to the supplementary protection 
certificate.

In order to obtain orphan designation in the EEA, the product must fulfill certain challenging criteria. Under Article 3 of Regulation (EC) 141/2000, 

a medicinal product may be designated as an orphan medicinal product if it meets the following criteria: (1) is intended for the diagnosis, prevention or 
treatment of a life-threatening or chronically debilitating condition; and (2) either the prevalence of such condition must not be more than five in 10,000 
persons in the EU when the application is made, or without the benefits derived from orphan status, it must be unlikely that the marketing of the medicine 
would generate sufficient return in the EU to justify the investment needed for its development; and (3) there exists no satisfactory method of diagnosis, 
prevention or treatment of such condition authorized for marketing in the EU or if such a method exists, the product will be of significant benefit to those 
affected by the condition, as defined in Regulation (EC) 847/2000.

Products receiving orphan designation in the EU may receive 10 years of orphan market exclusivity, which can be further extended by two years if 

pediatric studies have been conducted in accordance with an agreed pediatric investigational plan. Applications must first satisfy the orphan designation 
criteria and apply for orphan designation before making the application for marketing authorization. The applicant must then successfully maintain the 
orphan designation at the time of the marketing authorization application in order to qualify for 10 years of orphan market exclusivity. During this 10-year 
period, the competent authorities of the EU Member States and European Commission may not accept applications or grant marketing authorization for 
other similar medicinal products for the same orphan therapeutic indication. The protection afforded by orphan market exclusivity in the EU may, in some 
circumstances, be circumvented by competitor products which are demonstrated not to be "similar" or which are authorized for different therapeutic 
indications. There may be a risk that products may be prescribed "off-label" for the orphan therapeutic indication by healthcare professions in some EU 
Member States.

There are also three exceptions to the orphan market exclusivity principle. Marketing authorization may be granted to a similar medicinal product 

for the same orphan therapeutic indication if:

•

•

•

The second applicant can establish in its application that its medicinal product, although similar to the orphan medicinal product already 
authorized, is safer, more effective, or otherwise clinically superior;

The holder of the marketing authorization for the original orphan medicinal product consents to a second orphan medicinal product 
application; or

The holder of the marketing authorization for the original orphan medicinal product cannot supply sufficient quantities of orphan medicinal 
product.

An orphan product can also obtain an additional two years of orphan market exclusivity in the EU if the marketing authorization application 
contains the results of all pediatric studies conducted in accordance with and agreed pediatric investigation plan. The 10-year market exclusivity may be 
reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for orphan designation; for example, if the 
product is sufficiently profitable not to justify maintenance of market exclusivity.

The UK’s regulatory legal framework provides for similar periods of protection, namely regulatory data protection, marketing protection and market 

exclusivity.

It is important to note that the regulatory protection afforded to medicinal product such as data exclusivity, marketing protection, market exclusivity 
for orphan indications, and pediatric extension are currently under review at EU level. It is expected that the protection currently afforded in the EU will be 
reduced in the years to come.

Competition that our product candidates may face from generic versions of our product candidates could materially and adversely impact our future 
revenue, profitability and cash flows and substantially limit our ability to obtain a return on the investments we have made in those product candidates. Our 
future revenues, profitability, and cash flows could also be materially and adversely affected and our ability to obtain a return on the investments we have 
made in those product candidates may be substantially limited if our product candidates, if and when approved, are not afforded the appropriate periods of 
non-patent exclusivity.

Our operations and relationships with actual and potential customers, providers and third-party payors will be subject to applicable anti-
kickback, fraud and abuse, and other healthcare laws and regulations, which could expose us to penalties including criminal sanctions, civil penalties, 
exclusions from government programs, contractual damages, and reputational harm, and could diminish our future profits and earnings.

Our arrangements with third-party payors, physicians, and other potential customers will subject us to broadly applicable fraud and abuse and other 

healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we market, sell and distribute 
any drug candidates for which we obtain marketing approval.

Applicable U.S. federal and state healthcare laws and regulations include the following:

•

•

•

•

•

the federal Anti-Kickback Statute, a criminal law, which prohibits, among other things, persons and entities from knowingly and willfully 
offering, paying, soliciting or receiving any remuneration, directly or indirectly, in cash or in kind, to induce or reward purchasing, leasing, 
ordering, or arranging for, referring, or recommending the purchase, lease, or order of any good or service for which payment may be made, 
in whole or in part, under federal healthcare programs such as Medicare and Medicaid. A person or entity does not need to have actual 
knowledge of the statute or specific intent to violate it in order to have committed a violation. Violations of the federal Anti-Kickback Statute 
can result in significant civil monetary penalties and criminal fines, as well as imprisonment and exclusion from participation in federal 
healthcare programs;

the federal civil False Claims Act, which may be enforced through civil whistleblower or qui tam actions and imposes significant civil 
penalties, treble damages, and potential exclusion from federal healthcare programs against individuals or entities for, among other things, 
knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false or fraudulent or for making a 
false record or statement material to an obligation to pay the federal government or for knowingly and improperly avoiding, decreasing, or 
concealing an obligation to pay money to the federal government. Further, a violation of the federal Anti-Kickback Statute can serve as a 
basis for liability under the federal civil False Claims Act. There is also the federal Criminal False Claims Act, which is similar to the federal 
Civil False Claims Act and imposes criminal liability on those that make or present a false, fictitious, or fraudulent claim to the federal 
government;

the federal Civil Monetary Penalties Law, which authorizes the imposition of substantial civil monetary penalties against an entity that 
engages in activities including, among others (1) knowingly presenting, or causing to be presented, a claim for services not provided as 
claimed or that is otherwise false or fraudulent in any way; (2) arranging for or contracting with an individual or entity that is excluded from 
participation in federal health care programs to provide items or services reimbursable by a federal health care program; (3) violations of the 
federal Anti-Kickback Statute; or (4) failing to report and return a known overpayment;

federal criminal statutes created by the Health Insurance Portability and Accountability Act (HIPAA), which impose criminal liability for, 
among other things, knowingly and willfully executing or attempting to execute a scheme to defraud any healthcare benefit program, 
including private insurance plans, or, in any matter involving a healthcare benefit program, for knowingly and willfully making materially 
false, fictitious, or fraudulent statements in connection with the delivery of or payment for health care benefits;

HIPAA, as amended by HITECH, and its implementing regulations, which also imposes obligations, including mandatory contractual terms, 
on certain types of people and entities with respect to safeguarding the privacy, security and transmission of individually identifiable health 
information;

the FDCA which among other things, strictly regulates drug marketing, prohibits manufacturers from marketing such products for off-label 
use or misbranding or adulterating their products, and regulates the distribution of samples;

the federal and state laws that require pharmaceutical manufacturers to report certain calculated product pricing metrics to the government or 
provide certain discounts or rebates to government authorities or private entities, often as a condition of product coverage and reimbursement 
under federal healthcare programs

the federal Physician Payment Sunshine Act, which requires 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, among others, to annually 
track and report payments and other transfers of value provided to U.S.-licensed physicians and teaching hospitals, and for reports submitted 
on or after January 1, 2022, physician assistants, nurse practitioners, clinical nurse specialists, certified nurse anesthetists, anesthesiologist 
assistants, and certified nurse-midwives, as well as certain ownership and investment interests held by physicians and their immediate 
families;

analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, that may apply to our business practices, 
including sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party 
payors, including private insurers;

state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and relevant 
compliance guidance promulgated by the federal government;

state laws that require drug manufacturers to report information related to payments and other transfers of value to physicians and other 
healthcare providers or marketing expenditures;

other state laws that prohibit various marketing-related activities, such as the provision of certain kinds of gifts or meals; require the reporting 
of certain pricing information, including information pertaining to and justifying price increases, or prohibit prescription drug price gouging; 
and certain state and local laws that require the registration of pharmaceutical sales representatives; and

state and foreign laws that govern the privacy and security of health information in some circumstances, many of which differ from each 
other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve 

substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, 
regulations, or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any 
of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties; 
damages; fines; imprisonment; exclusion of drug candidates from government-funded healthcare programs, such as Medicare and Medicaid; disgorgement; 
contractual damages; reputational harm; diminished profits and future earnings; and the curtailment or restructuring of our operations. If any physicians or 
other healthcare providers or entities with whom we expect to do business are found not to be in compliance with applicable laws, they may also be subject 
to criminal, civil, or administrative sanctions, including exclusions from government-funded healthcare programs. Although effective compliance programs 
can mitigate the risk of investigation and prosecution for violations of these laws, these risks cannot be entirely eliminated. Any action for an alleged or 
suspected violation can cause us to incur significant legal expenses and divert management’s attention from the operation of the business, even if such 
action is successfully defended.

Providing benefits or advantages to induce or reward improper performance generally to induce or encourage the prescription, recommendation, 
endorsement, purchase, supply, order, or use of medicinal products is prohibited in the EU. The provision of benefits or advantages to induce or reward 
improper performance is governed by the national anti-bribery laws of EU Member States, and in respect of the U.K., the Bribery Act 2010. Infringement 
of these laws may result in substantial fines and imprisonment. EU Directive 2001/83/EC, which is the EU Directive governing medicinal products for 
human use, provides that, where medicinal products are being promoted to 

64

 
healthcare professionals, no gifts, pecuniary advantages, or benefits in kind may be supplied, offered or promised to such individuals unless they are 
inexpensive and relevant to the practice of medicine or pharmacy. This provision was transposed into the Human Medicines Regulations 2012 and as such 
remains applicable in the UK.

Payments made to physicians in certain EU Member States must be publicly disclosed. In addition, agreements with healthcare professionals must 
often be the subject of prior notification and approval by the healthcare professional’s employer, his or her competent professional organization, and/or the 
regulatory authorities of individual EU Member States. These requirements are set out in national laws, industry codes, or professional codes of conduct, 
applicable in the EU Member States and in the UK. Failure to comply with these requirements could result in reputational risk, public reprimands, 
administrative penalties, fines, or imprisonment.

If we market products in a manner that violates healthcare fraud and abuse laws, or if we violate government price reporting laws, we may be subject to 
civil or criminal penalties. 

In addition to FDA restrictions on the marketing of pharmaceutical products, several other types of state and federal healthcare fraud and abuse laws 

have been applied in recent years to restrict certain marketing practices in the pharmaceutical industry. These laws include false claims statutes and anti-
kickback statutes. Because of the breadth of these laws and the narrowness of the safe harbors, it is possible that some of our business activities could be 
subject to challenge under one or more of these laws. 

Federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal 
government or knowingly making, or causing to be made, a false statement to get a false claim paid. The federal healthcare program anti-kickback statute 
prohibits, among other things, knowingly and willfully offering, paying, soliciting, or receiving remuneration to induce, or in return for, purchasing, 
leasing, ordering, or arranging for the purchase, lease, or order of any healthcare item or service reimbursable under Medicare, Medicaid, or other federally 
financed healthcare programs. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand, and 
prescribers, purchasers, and formula managers on the other. Although there are several statutory exemptions and regulatory safe harbors protecting certain 
common activities from prosecution, the exemptions and safe harbors are drawn narrowly, and practices that involve remuneration intended to induce 
prescribing, purchasing, or recommending may be subject to scrutiny if they do not qualify for an exemption or safe harbor. Our practices may not in all 
cases meet all of the criteria for safe harbor protection from anti-kickback liability. 

Over the past few years, several pharmaceutical and other healthcare companies have been prosecuted under these laws for a variety of alleged 

promotional and marketing activities, such as: allegedly providing free trips, free goods, sham consulting fees and grants, and other monetary benefits to 
prescribers; reporting to pricing services inflated average wholesale prices that were then used by federal programs to set reimbursement rates; engaging in 
off-label promotion that caused claims to be submitted to Medicaid for non-covered, off-label uses; and submitting inflated best price information to the 
Medicaid Rebate Program to reduce liability for Medicaid rebates. Most states also have statutes or regulations similar to the federal anti-kickback law and 
false claims laws, which apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the 
payor. Sanctions under these federal and state laws may include civil monetary penalties, exclusion of a manufacturer’s products from reimbursement under 
government programs, criminal fines, and imprisonment. 

Inadequate 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 business 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 the 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.

65

 
Disruptions at the FDA and other agencies, including as a result of or in response to the COVID-19 pandemic, 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 
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, in our 
operations as a public company, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to 
properly capitalize and continue our operations.

The FDA’s ability to review and approve new products may be hindered by a variety of factors, including budget and funding levels; ability to hire and 
retain key personnel; and statutory, regulatory, and policy changes. 

The ability of the FDA to review and approve new products can be affected by a variety of factors, including budget and funding levels; ability to

In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is 
inherently fluid and unpredictable. 

The ability of the FDA and other government agencies to properly administer their functions is highly dependent on the levels of government 
funding and the ability to fill key leadership appointments, among various factors. Delays in filling or replacing key positions could significantly impact the 
ability of the FDA and other agencies to fulfill their functions, and could greatly impact healthcare and the pharmaceutical industry. 

In December 2016, the 21st Century Cures Act was signed into law, and was designed to advance medical innovation and empower the FDA with 
the authority to directly hire positions related to drug and device development and review. In the past, the FDA was often unable to offer key leadership 
candidates (including scientists) competitive compensation packages as compared to those offered by private industry. The 21st Century Cures Act is 
designed to streamline the agency’s hiring process and enable the FDA to compete for leadership talent by expanding the narrow ranges that are provided in 
the existing compensation structures. 

66

 
Disruptions at the FDA and other governmental 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 operating results and business. 

Failure to obtain regulatory approval in foreign jurisdictions would prevent us from marketing and commercializing our products abroad and may 
limit our ability to generate revenue from product sales.

We intend to market and commercialize our product candidates internationally. To market and sell our drug candidates in jurisdictions outside the 

United States, we must obtain separate marketing approvals and comply with numerous and varying regulatory requirements. The approval procedure 
varies among countries and can involve additional testing. The time required to obtain approval may differ substantially from that required to obtain FDA 
approval. The regulatory approval process outside the United States generally includes all of the risks associated with obtaining FDA approval. In addition, 
in many countries outside the United States, we must secure product reimbursement approvals before regulatory authorities will approve the product for 
sale in that country. Failure to obtain foreign regulatory approvals on a timely basis or non-compliance with foreign regulatory requirements could result in 
significant delays, difficulties, and costs for us and could delay or prevent the introduction of our drug candidates in certain countries. Approval by the 
FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside the United 
States does not ensure approval by regulatory authorities in other countries or jurisdictions or by the FDA. We may not be able to file for marketing 
approvals and may not receive necessary approvals to commercialize our products in any jurisdiction, which would materially impair our ability to generate 
revenue.

The UK's exit from the EU continues to create political and economic uncertainty, particularly in the UK and the EU. The UK is now being treated 

as a "third country" by the EU and new UK legislation has taken effect. This means that some regulatory activities, such as batch testing and Qualified 
Person certification conducted in Great Britain is no longer recognized in the EU. However, the UK and EU have concluded a Trade and Cooperation 
Agreement (TCA), which has been approved by the UK Parliament, European Council and European Parliament and has limited the disruption to the 
supply of medicines, particularly by enabling tariff and quota-free trade between the UK and the EU (provided that the rules of origin requirements are 
met), and has streamlined some issues, for example by enabling mutual recognition of cGMP inspections and certificates. The regulatory framework for 
medicines that existed before the end of the transition period has also effectively been preserved in UK domestic legislation as "retained EU law." By 
retaining a snapshot of EU legislation at its core, the UK has prevented substantial divergence to the regulation of medicines (although divergence has 
appeared in some areas). However, some changes to the UK legislation have been immediately necessary, including the implementation of the Northern 
Ireland Protocol (NIP), pursuant to which, the EU pharmaceutical legal framework acquis continues to apply in Northern Ireland (subject to periodic 
consent of the Northern Ireland Legislative Assembly), and only products compliant with EU law can be placed in the Northern Ireland market - adding an 
extra layer of regulatory complexity. As companies now need to comply with a separate UK regulatory legal framework in order to commercialize 
medicinal products in Great Britain (namely, England, Wales and Scotland, as EU law continues to apply in Northern Ireland). The UK government is 
currently trying to renegotiate fundamental aspects of the NIP so this is an unpredictable area for companies in the near future. The TCA allows for future 
deviation from the current regulatory framework and it is not known if and/or when any deviations may occur, which may have an impact on development, 
manufacture, marketing authorization, commercial sales and distribution of pharmaceutical products. It is also important to note that obtaining a marketing 
authorization is not sufficient to gain effective access to the market in the EU and in the UK; companies still need to agree to a reimbursement price for the 
products and in some jurisdictions, such as the UK and Germany, a further positive recommendation from health technology on cost-effectiveness is 
required for the products to be actually prescribed and reimbursed by the respective national health systems (see below). If we fail to comply with the 
regulatory requirements in international markets and thus receive applicable marketing approvals, our target market will be reduced, our ability to realize 
the full market potential of our drug candidates will be harmed and our business will be adversely affected. We may not obtain foreign regulatory approvals 
on a timely basis, if at all. Our failure to obtain approval of any of our drug candidates by regulatory authorities in another country may significantly 
diminish the commercial prospects of that drug candidate and our business prospects could decline.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of reproxalap or 
our other product candidates. 

We face an inherent risk of product liability as a result of the clinical testing of reproxalap and our other product candidates and will face an even 

greater risk if we commercialize our product candidates. For example, we may be sued if reproxalap or our other product candidates allegedly cause injury 
or are found to be otherwise unsuitable during product testing, manufacturing, marketing, or sale. Any such product liability claims may include allegations 
of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product candidate, negligence, strict liability, and a breach of 
warranties. Claims could also be asserted under state consumer protection acts. 

If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit 

commercialization of our product candidates. Even successful defense would require significant financial and management resources. Regardless of the 
merits or eventual outcome, liability claims may result in: 

•

•

•

•

•

•

•

•

•

•

decreased demand for reproxalap or our other product candidates; 

injury to our reputation; 

withdrawal of clinical trial participants; 

costs to defend the related litigation; 

a diversion of management’s time and our resources; 

substantial monetary awards to trial participants or patients; 

product recalls, withdrawals or labeling, marketing or promotional restrictions; 

loss of revenue; 

the inability to continue to develop or commercialize reproxalap or our other product candidates; or 

a decline in our stock price. 

We maintain product liability insurance with $5.0 million in coverage. Our inability to obtain and retain sufficient product liability insurance at an 

acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of reproxalap or our other product 
candidates. Although we will maintain such insurance, any claim that may be brought against us could result in a court judgment or settlement in an 
amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits of our insurance coverage. Our insurance policies will also 
have various exclusions, and we may be subject to a product liability claim for which we have no coverage. We may have to pay any amounts awarded by a 
court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, 
sufficient capital to pay such amounts. 

We and our development partners, third-party manufacturers, and suppliers use biological materials and may use hazardous materials, and any claims 
relating to improper handling, storage, or disposal of these materials could be time consuming or costly. 

We and our development partners, third-party manufacturers, and suppliers may use hazardous materials, including chemicals and biological agents 

and compounds that could be dangerous to human health and safety or the environment. Our operations and the operations of our development partner, 
third-party manufacturers, and suppliers also produce hazardous waste products. Federal, state, and local laws and regulations govern the use, generation, 
manufacture, storage, handling, and disposal of these materials and wastes. Compliance with applicable environmental laws and regulations may be 
expensive, and current or future environmental laws and regulations may impair our product development efforts. In addition, we cannot entirely eliminate 
the risk of accidental injury or contamination from these materials or wastes. We do not carry specific biological or hazardous waste insurance coverage 
and our property, casualty, and general liability insurance policies specifically exclude coverage for damages and fines arising from biological or hazardous 
waste exposure or contamination. Accordingly, in the event 

68

 
of contamination or injury we could be held liable for damages or be penalized with fines in an amount exceeding our resources, and our clinical trials or 
regulatory approvals could be suspended. 

We and any of our future development partners will be required to report to regulatory authorities if any of our approved products cause or contribute 
to adverse medical events, and any failure to do so would result in sanctions that would materially harm our business. 

If we and any of our future development partners are successful in commercializing our products, the FDA and foreign regulatory authorities will 
require that we and any of our future development partners report certain information about adverse medical events if those products may have caused or 
contributed to those adverse events. The timing of our obligation to report would be triggered by the date we become aware of the adverse event as well as 
the nature of the event. We and any of our future development partners may fail to report adverse events we become aware of within the prescribed 
timeframe or to perform inadequate investigations of their causes. We and any of our future development partners may also fail to appreciate that we have 
become aware of a reportable adverse event, especially if it is not reported to us as an adverse event or if it is an adverse event that is unexpected or 
removed in time from the use of our products. If we and any of our future development partners fail to comply with our reporting obligations, the FDA or a 
foreign regulatory authority could take enforcement action including the issuance of a Warning Letter, the requirement of a labeling change, the initiation of 
a criminal prosecution, the imposition of civil monetary penalties, the seizure of our products, or delay in approval or clearance of future products. 

We are subject to anti-corruption laws, as well as export control laws, customs laws, sanctions laws, and other laws governing our operations. If 
we fail to comply with these laws, we could be subject to civil or criminal penalties, or other remedial measures and legal expenses, any of which could 
adversely affect our business, results of operations and financial condition.

Our operations are subject to anti-corruption laws, including the Foreign Corrupt Practices Act (FCPA), the Bribery Act and other anticorruption 

laws that apply in countries where we do business and may do business in the future. The FCPA, the Bribery Act, and other laws generally prohibit us, our 
officers, and our employees, and intermediaries from bribing, being bribed, or making other prohibited payments to government officials or other persons 
to obtain or retain business or gain some other business advantage. We may in the future operate in jurisdictions that pose a high risk of potential FCPA or 
Bribery Act violations, and we may participate in collaborations and relationships with third parties whose actions could potentially subject us to liability 
under the FCPA, the Bribery Act, or local anti-corruption laws. In addition, we cannot predict the nature, scope or effect of future regulatory requirements 
to which our international operations might be subject or the manner in which existing laws might be administered or interpreted.

We also are subject to other laws and regulations governing our international operations, including regulations administered by the governments of 

the United States, UK, and authorities in the EU, including applicable export control regulations, economic sanctions on countries and persons, customs 
requirements, and currency exchange regulations, which we collectively refer to as Trade Control Laws.

There is no assurance that we will be completely effective in ensuring our compliance with all applicable anti-corruption laws, including the FCPA, 

the Bribery Act, or other legal requirements including Trade Control Laws. If we are not in compliance with the FCPA, the Bribery Act, and other anti-
corruption laws or Trade Control Laws, we may be subject to criminal and civil penalties, legal expenses, disgorgement, and other sanctions and remedial 
measures, which could have an adverse impact on our business, financial condition, results of operations, or liquidity. The SEC also may suspend or bar 
issuers from trading securities on U.S. exchanges for violations of the FCPA’s accounting provisions. Likewise, any investigation of any potential violations 
of the FCPA; the Bribery Act; or other anti-corruption laws or Trade Control Laws by U.S., U.K., or other authorities also could have an adverse impact on 
our reputation, our business, results of operations, or financial condition.

Risks Related to our Reliance on Third Parties

We rely and will continue to rely on outsourcing arrangements for many of our activities, including clinical development and supply of reproxalap and 
our other product candidates. 

As of December 31, 2021, we had only 12 full-time employees and, as a result, we rely, and expect to continue to rely, on outsourcing arrangements 

for a significant portion of our activities, including clinical research, data collection and analysis, manufacturing, financial reporting and accounting, and 
human resources, as well as for certain functions required of publicly traded companies. We may have limited control over third parties and we cannot 
guarantee that any third party will perform its obligations in an effective and timely manner. 

In addition, during challenging and uncertain economic environments, in tight credit markets and during public health epidemics, such as the 
COVID-19 pandemic, and with the political uncertainty involving Russia and Ukraine, there may be a disruption or delay in the performance of our third 
party contractors, suppliers, or partners. If such third parties are unable to satisfy their commitments to us, our business and results of operations would be 
adversely affected. 

We rely on third parties to conduct our clinical trials. If any third party does not meet our deadlines or otherwise conduct the trials as required and in 
accordance with regulations, our clinical development programs could be delayed or unsuccessful and we may not be able to obtain regulatory 
approval for or successfully commercialize our product candidates when expected, or at all. 

We do not have the ability to conduct all aspects of our preclinical testing or clinical trials ourselves. We are dependent on third parties to conduct 
the clinical trials for reproxalap and for our other product candidates and, therefore, the timing of the initiation and completion of these trials is controlled 
by such third parties and may occur on substantially different timing from our estimates. Specifically, we use CROs to conduct our clinical trials and we 
also rely on medical institutions, clinical investigators, and consultants to conduct our trials in accordance with our clinical protocols and regulatory 
requirements. Our CROs, investigators, and other third parties play a significant role in the conduct of these trials and subsequent collection and analysis of 
data. 

There is no guarantee that CROs, investigators, or other third parties on which we rely for administration and conduct of our clinical trials will 
devote adequate time and resources to such trials or perform as contractually required. If any of these third parties fails to meet expected deadlines, fails to 
adhere to our clinical protocols, or otherwise performs in a substandard manner, our clinical trials may be extended, delayed, or terminated. If any of our 
clinical trial sites terminates for any reason, we may experience the loss of follow-up information on subjects enrolled in our ongoing clinical trials unless 
we are able to transfer those subjects to another qualified clinical trial site. In addition, principal investigators for our clinical trials may serve as scientific 
advisors or consultants to us from time to time, and may receive cash or equity compensation in connection with such services. The COVID-19 pandemic 
or any worsening of the global business and economic environment may have the effect of heightening or exacerbating these risks.

Some of our product candidates may be studied in clinical trials co-sponsored by organizations or agencies other than us, or in investigator-initiated 
clinical trials, which means we have minimal or no control over the conduct of such trials. 

We currently anticipate that part of our strategy for pursuing the wide range of indications potentially addressed by our product candidates will 

involve investigator-initiated clinical trials. Investigator-initiated clinical trials pose similar risks as those set forth elsewhere in this “Risk Factor” section 
relating to our internal clinical trials. While investigator-initiated trials may provide us with clinical data that can inform our future development strategy, 
we generally have less control over the conduct and design of the trials. Because we are not the sponsors of investigator-initiated trials, we do not control 
the protocols, administration, or conduct of the trials, including follow-up with patients and ongoing collection of data after treatment. As a result, we are 
subject to risks associated with the way investigator-initiated trials are conducted. In particular, we may be named in lawsuits that would lead to increased 
costs associated with legal defense. Additional risks include difficulties or delays in communicating with investigators or administrators, procedural delays 
and other timing issues, and difficulties or differences in interpreting data. Third-party investigators may design clinical trials with clinical endpoints that 
are more difficult to achieve, or in other ways that increase the risk of negative clinical trial results compared to clinical trials that we 

70

 
may design on our own. Negative results in investigator-initiated clinical trials could have a material adverse effect on our prospects and the perception of 
our product candidates. As a result, our lack of control over the conduct and timing of, and communications with the FDA regarding, investigator-
sponsored trials expose us to additional risks and uncertainties, many of which are outside our control, and the occurrence of which could adversely affect 
the commercial prospects for our product candidates. 

We rely completely on third parties to supply drug substance and manufacture drug product for our clinical trials and preclinical studies. We intend to 
rely on other third parties to produce commercial supplies of product candidates, and our dependence on third parties could adversely impact our 
business. 

We are completely dependent on third-party suppliers of the drug substance and drug product for our product candidates. If third-party suppliers do 

not supply sufficient quantities of materials to us on a timely basis and in accordance with applicable specifications and other regulatory requirements, 
there could be a significant interruption of our supplies, which would adversely affect clinical development and commercialization. Furthermore, if any of 
our contract manufacturers cannot successfully manufacture material that conforms to our specifications within regulatory requirements, we will not be 
able to secure and/or maintain regulatory approval, if any, for our product candidates. 

We also rely on our contract manufacturers to purchase from third-party suppliers the materials necessary to produce our product candidates for our 

anticipated clinical trials. We do not have any control over the process or timing of the acquisition of raw materials by our contract manufacturers. 
Moreover, we currently do not have agreements in place for the commercial production of these raw materials. Any significant delay in the supply of a 
product candidate or the raw material components thereof for an ongoing clinical trial, including as a result of the COVID-19 pandemic or the conflict 
between Russia and Ukraine, could considerably delay completion of that clinical trial, product candidate testing, and potential regulatory approval of that 
product candidate. 

We do not expect to have the resources or capacity to commercially manufacture any of our proposed product candidates if approved and will likely 
continue to be dependent on third-party manufacturers. Our dependence on third parties to manufacture and supply clinical trial materials and any approved 
product candidates may adversely affect our ability to develop and commercialize our product candidates on a timely basis. 

We may not be successful in establishing and maintaining development, commercial, or other strategic partnerships, which could adversely affect our 
ability to develop and commercialize product candidates. 

We have in the past chosen, and may in the future choose, to enter into development or other strategic partnerships, including collaborations with 

major biotechnology or pharmaceutical companies. We face significant competition in seeking appropriate partners and the negotiation process is time 
consuming and complex. Moreover, we may not be successful in our efforts to establish other development partnerships or other alternative arrangements 
for any of our product candidates or programs because our research and development pipeline may be insufficient, our product candidates or programs may 
be deemed to be at too early a stage of development for collaborative effort, and/or third parties may not view our product candidates or programs as 
having the requisite commercial or technical potential. Even if we are successful in our efforts to establish development or commercial partnerships, the 
terms that we agree upon may not be favorable to us and we may not be able to maintain such partnerships if, for example, development or approval of a 
product candidate is delayed or sales of an approved product candidate are below expectations. Any delay in entering into development partnership 
agreements related to our product candidates could delay the development and commercialization of our product candidates and reduce competitiveness, if 
approved. 

Moreover, if we fail to maintain partnerships related to our product candidates: 

•

•

•

the development of certain of our current or future product candidates may be terminated or delayed; 

our cash expenditures related to development and commercialization of certain of our current or future product candidates would increase 
significantly and we may need to seek additional financing; 

we may be required to hire additional employees or otherwise develop expertise, such as sales and marketing expertise, for which we have 
not budgeted; and 

71

 
•

we will bear all of the risk related to the development and commercialization of any such product candidates. 

We may not realize the benefits of our current or future strategic alliances. 

We have in the past, and may in the future, form strategic alliances, create joint ventures or collaborations, or enter into licensing arrangements with 
third parties that we believe will complement or augment our existing business, including the continued development or commercialization of reproxalap or 
our other product candidates. Strategic alliances may require us to incur non-recurring and other charges, increase our near- and long-term expenditures, 
issue securities that dilute our existing stockholders, or disrupt our management and business. In addition, we face significant competition in seeking 
appropriate strategic partners, and the negotiation process is time-consuming and complex. Moreover, we may not be successful in our efforts to establish a 
strategic partnership or other alternative arrangements for reproxalap or our other product candidates because third parties may view the risk of 
development failure as too significant or the commercial opportunity for our product candidate as too limited. We cannot be certain that, following a 
strategic transaction or license, we will achieve the revenues or specific net income that justifies such transaction. 

Risks Relating to Our Intellectual Property 

Our success depends on our and our licensors' ability to protect our intellectual property and our proprietary technologies. 

Our commercial success depends in part on our ability to obtain and maintain patent protection and trade secret protection for our product 
candidates, proprietary technologies, and the use of our product candidates or proprietary technologies as well as our ability to operate without infringing 
upon the proprietary rights of others. There can be no assurance that our patent applications or those of our licensors will result in additional patents being 
issued or that issued patents will afford sufficient protection against competitors with similar technology, nor can there be any assurance that the patents 
issued will not be infringed, designed around, or invalidated by third parties. Even issued patents may later be found unenforceable or may be modified or 
revoked in proceedings instituted by third parties before various patent offices or in courts. The degree of future protection for our proprietary rights is 
uncertain. Only limited protection may be available and may not adequately protect our rights or permit us to gain or keep any competitive advantage. This 
failure to properly protect the intellectual property rights relating to these product candidates could have a material adverse effect on our financial condition 
and results of operations. 

Composition-of-matter patents on the active pharmaceutical ingredient are generally considered to be the strongest form of intellectual property 
protection for pharmaceutical products, as such patents provide protection without regard to any method of use. While we have issued composition-of-
matter patents in the United States and other countries for reproxalap and other product candidates, we cannot be certain that the claims in our patent 
applications covering composition-of-matter of early stage candidates will be considered patentable by the United States Patent and Trademark Office 
(USPTO) and courts in the United States or by the patent offices and courts in foreign countries, nor can we be certain that the claims in our issued 
composition-of-matter patents will not be found invalid or unenforceable if challenged. Method-of-use patents protect the use of a product for the specified 
method. This type of patent does not prevent a competitor from making and marketing a product that is identical to our product for an indication that is 
outside the scope of the patented method. Moreover, even if competitors do not actively promote their product for our targeted indications, physicians may 
prescribe these products off-label. Although off-label prescriptions may infringe or contribute to the infringement of method-of-use patents, the practice is 
common and such infringement is difficult to prevent or prosecute. In addition, there are possibly treatment compositions and methods that we have not 
conceived of or attempted to patent, and other parties may discover and patent approaches and compositions that are similar to or different from ours. 

The patent application process is subject to numerous risks and uncertainties, and there can be no assurance that we or any of our future 

development partners will be successful in protecting our product candidates by obtaining and defending patents. These risks and uncertainties include the 
following: 

•

the USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment, 
and other provisions during the patent process. There are 

72

 
 
situations in which noncompliance can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of 
patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would otherwise have 
been the case; 

•

•

•

•

•

patent applications may not result in any patents being issued; 

patents that may be issued or in-licensed may be challenged, invalidated, modified, revoked, circumvented, found to be unenforceable, or 
otherwise may not provide any competitive advantage; 

our competitors, many of whom have substantially greater resources than we do and many of whom have made significant investments in 
competing technologies, may seek or may have already obtained patents that will limit, interfere with, or eliminate our ability to make, use, 
and sell our potential product candidates; 

there may be significant pressure on the United States government and international governmental bodies to limit the scope of patent 
protection both inside and outside the United States for disease treatments that prove successful, as a matter of public policy regarding 
worldwide health concerns; and 

countries other than the United States may have patent laws less favorable to patentees than those upheld by United States courts, allowing 
foreign competitors a better opportunity to create, develop, and market competing product candidates. 

In addition, we rely on the protection of our trade secrets and proprietary know-how. Although we have taken steps to protect our trade secrets and 
unpatented know-how, including entering into confidentiality agreements with third parties, and confidential information and inventions agreements with 
employees, consultants, and advisors, third parties may still obtain this information or may come upon this or similar information independently. If any of 
these events occurs or if we otherwise lose protection for our trade secrets or proprietary know-how, the value of our trade secrets or proprietary know-how 
may be greatly reduced. 

Claims by third parties that we infringe their proprietary rights may result in liability for damages or prevent or delay our developmental and 
commercialization efforts. 

The biotechnology industry has been characterized by frequent litigation regarding patent and other intellectual property rights. Because patent 

applications are maintained in secrecy until the application is published, we may be unaware of third party patents that may be infringed by 
commercialization of reproxalap or our other product candidates. In addition, identification of third party patent rights that may be relevant to our 
technology is difficult because patent searching is imperfect due to differences in terminology among patents, incomplete databases, and the difficulty in 
assessing the meaning of patent claims. Any claims of patent infringement asserted by third parties would be time consuming and could likely: 

•

•

•

•

•

•

result in costly litigation; 

divert the time and attention of our technical personnel and management; 

cause development or commercialization delays; 

prevent us from commercializing reproxalap or our other product candidates until the asserted patent expires or is held finally invalid or not 
infringed in a court of law; 

require us to develop non-infringing technology; or 

require us to enter into royalty or licensing agreements. 

Although no third party has asserted a claim of patent infringement against us, others may hold proprietary rights that could prevent reproxalap or 

our other product candidates from being marketed. Any patent-related legal action against us claiming damages and seeking to enjoin commercial activities 
relating to our product candidate or processes could subject us to potential liability for damages and require us to obtain a license to continue to 
manufacture or market reproxalap or our other product candidates. We cannot predict whether we would prevail in any such actions or that any license 
required under any of these patents would be made available on commercially acceptable terms, if at all. In addition, we cannot be sure that we could 
redesign our product candidate or processes 

73

 
to avoid infringement, if necessary. Accordingly, an adverse determination in a judicial or administrative proceeding, or the failure to obtain necessary 
licenses, could prevent us from developing and commercializing reproxalap or our other product candidates, which could harm our business, financial 
condition, and operating results. 

Any such claims against us could also be deemed to constitute an event of default under the loan and security agreement. In the case of a continuing 

event of default under the loan, Hercules, could, among other remedies, elect to declare all amounts outstanding to be immediately due and payable and 
terminate all commitments to extend further credit. In the event we do not or are not able to repay the obligations at the time a default occurred, Hercules 
may elect to commence and prosecute bankruptcy and/or other insolvency proceedings, or proceed against the collateral granted to Hercules under the loan.

Our issued patents could be found invalid or unenforceable if challenged in court. 

If we or any of our future development partners were to initiate legal proceedings against a third party to enforce a patent covering one of our 

product candidates, or one of our future product candidates, the defendant could counterclaim that our patent is invalid and/or unenforceable. In patent 
litigation in the United States, defendant counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge could 
be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, or non-enablement. Grounds for an 
unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO, or 
made a misleading statement during prosecution. Third parties may also raise similar claims before the USPTO, even outside the context of litigation. The 
outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to validity, for example, we cannot be certain that there 
is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of 
invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on such product candidate. Such a loss of patent 
protection would have a material adverse impact on our business. 

We may fail to comply with any of our obligations under existing or future agreements pursuant to which we license rights or technology, which could 
result in the loss of rights or technology that are material to our business. 

We are a party to technology licenses, including the in-license agreement for ADX-1612 and an in-license agreement for ADX-2191, and we may 

enter into additional licenses in the future. Such licenses do, and may in the future, impose commercial, contingent payment, royalty, insurance, 
indemnification, and other obligations on us. If we fail to comply with these obligations, the licensor may have the right to terminate the license, in which 
event we could lose valuable rights under our collaboration agreements and our ability to develop product candidates could be impaired. Additionally, 
should such a license agreement be terminated for any reason, there may be a limited number of replacement licensors, and a significant amount of time 
may be required to transition to a replacement licensor. 

74

 
Our rights to develop and commercialize ADX-1612 and ADX-2191 are each subject in part to the terms and conditions of a third party license, 
pursuant to which we have acquired exclusive rights to ADX-1612 and ADX-2191 and other intellectual property. Our rights with respect to the intellectual 
property to develop and commercialize ADX-1612 and ADX-2191 may terminate, in whole or in part, if we fail to meet certain milestones contained in 
each of our license agreements relating to the development and commercialization of ADX-1612 and ADX-2191. We may also lose our rights to develop 
and commercialize either of ADX-1612 or ADX-2191 if we fail to pay required milestones or royalties. In the event of an early termination of our license 
agreement, all rights licensed and developed by us under this agreement may be extinguished, which may have an adverse effect on our business and results 
of operations. 

We may be subject to claims that we have wrongfully hired an employee from a competitor or that we or our employees, consultants, or agents have 
wrongfully used or disclosed alleged confidential information or trade secrets of their former employers. 

As is common in the biotechnology and pharmaceutical industry, we engage the services of consultants to assist us in the development of our 

product candidates. Many of these consultants and our employees were previously employed at, or may have previously provided or may be currently 
providing consulting services to, other biotechnology or pharmaceutical companies including our competitors or potential competitors. We may become 
subject to claims that our company or an employee, consultant, or agent inadvertently or otherwise used or disclosed trade secrets or other information 
proprietary to their former employers or their former or current clients. Litigation may be necessary to defend against these claims. Even if we are 
successful in defending against these claims, litigation could result in substantial costs and be a distraction to our management team. 

If we do not obtain protection under the Hatch-Waxman Amendments by extending the patent terms and obtaining data exclusivity for our product 
candidate, our business may be materially harmed. 

Depending upon the timing, duration, and specifics of FDA marketing approval of reproxalap or other product candidates, one or more of our 
United States patents may be eligible for limited patent term restoration under the Drug Price Competition and Patent Term Restoration Act of 1984, 
referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation for 
patent term lost during product development and the FDA regulatory review process. However, we may not be granted an extension because of, for 
example, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents, or otherwise failing to satisfy applicable 
requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If we are unable to obtain 
patent term extension or restoration or the term of any such extension is less than we request, our competitors may obtain approval of competing products 
following our patent expiration, and our revenue could be reduced, possibly materially. 

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our 
business may be adversely affected. 

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest, and 

our business may be adversely affected. Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented, or declared 
generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names, which we need to 
build name recognition among potential partners or customers in our markets of interest. At times, competitors may adopt trade names or trademarks 
similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade 
name or trademark infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of our registered or 
unregistered trademarks or trade names. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then 
we may not be able to compete effectively, and our business may be adversely affected. Our efforts to enforce or protect our proprietary rights related to 
trademarks, trade secrets, domain names, copyrights, or other intellectual property may be ineffective and could result in substantial costs and diversion of 
resources, and could adversely impact our financial condition or results of operations.

Changes in United States patent law could diminish the value of patents in general, thereby impairing our ability to protect our product candidates. 

As is the case with other biotechnology companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and 

enforcing patents in the biopharmaceutical industry involves technological and legal complexity. Therefore, obtaining and enforcing biotechnology patents 
is costly, time consuming, and inherently uncertain. In addition, Congress may pass patent reform legislation. The Supreme Court has ruled on several 
patent cases in recent years, either narrowing the scope of patent protection available or weakening the rights of patent owners. In addition to increasing 
uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, 
once obtained. Depending on decisions by the United States Congress, the federal courts, and the USPTO, the laws and regulations governing patents could 
change in unpredictable ways that would weaken our ability to obtain new patents, or to enforce our existing patents and patents we might obtain in the 
future. 

We may not be able to protect our intellectual property rights throughout the world. 

While we have issued composition-of-matter patents covering reproxalap and certain of our other product candidates in the United States and other 

countries, filing, prosecuting, and defending patents on reproxalap and our other product candidates in all countries throughout the world would be 
prohibitively expensive, and our intellectual property rights in some countries outside the United States may be less extensive and of significantly shorter 
duration than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as 
federal and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside 
the United States, or from selling or importing products made using our inventions in and into the United States or other jurisdictions. Competitors may use 
our technologies in jurisdictions where we have not obtained patent protection to develop their own products, and, further, may export otherwise infringing 
products to territories where we have patent protection, but where enforcement is not as strong as that in the United States. These products may compete 
with our product candidates, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing. 

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal 
systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, 
particularly those relating to pharmaceuticals, which could make it difficult for us to stop the infringement of our patents or marketing of competing 
products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and 
divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly, could put our 
patent applications at risk of not issuing, and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and 
the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights 
around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license. 

Risks Related to Our Common Stock 

In the absence of an active trading market for our common stock, investors may not be able to resell their shares at or above the price at which they 
purchased them. 

In the absence of an active trading market for our common stock, investors may not be able to sell their common stock at or above the price they 

paid or at the time that they would like to sell. In addition, an inactive market may impair our ability to raise capital by selling shares and may impair our 
ability to acquire other companies or technologies by using our shares as consideration, which, in turn, could harm our business. 

76

 
The trading price of the shares of our common stock has been and is likely to continue to be highly volatile, and purchasers of our common stock could 
incur substantial losses. 

Our stock price has been and will likely continue to be volatile for the foreseeable future. The stock market in general and the market for 

biotechnology companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular 
companies. As a result of this volatility, investors may not be able to sell their common stock at or above the price they paid. The market price for our 
common stock may be influenced by many factors, including: 

•

•

•

•

•

•

•

•

•

•

•

•

•

•

results of clinical trials, and the results of trials of our competitors or those of other companies in our market sector; 

the results and status of our research and development and regulatory plans for our product candidates;

the expectations of investors or securities analysts regarding our business and clinical development program, including interim or final top-
line results that we may announce;

regulatory developments in the United States and foreign countries; 

our ability to enroll and retain patients in our clinical trials;

variations in our financial results or those of companies that are perceived to be similar to us; 

changes in the structure of healthcare payment systems, especially in light of current reforms to the United States healthcare system; 

announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures, or capital commitments; 

market conditions in the pharmaceutical and biotechnology sectors and issuance of securities analysts’ reports or recommendations; 

sales of our stock by insiders and 5% stockholders; 

trading volume of our common stock; 

general economic, industry, regional or larger scale conflicts or geo-political actions, and market conditions other events or factors, many of 
which are beyond our control, including frequent and dramatic fluctuations in industry indexes that may contain or influence our stock; 

additions or departures of key personnel; and 

intellectual property, product liability, or other litigation against us. 

In addition, in the past, stockholders have initiated class action lawsuits against biotechnology and pharmaceutical companies following periods of 

volatility in the market prices of these companies’ stock. Such litigation, if instituted against us, could cause us to incur substantial costs and divert 
management’s attention and resources, which could have a material adverse effect on our business, financial condition, and results of operations. 

Our failure to meet the continued listing requirements of The Nasdaq Capital Market could result in a delisting of our common stock. 

If we fail to satisfy the continued listing requirements of The Nasdaq Capital Market (Nasdaq), such as the corporate governance requirements or the 

minimum closing bid price requirement, Nasdaq may take steps to de-list our common stock. Such a delisting would likely have a negative effect on the 
price of our common stock and would impair your ability to sell or purchase our common stock when you wish to do so. In the event of a delisting, we 
would expect to take actions to restore our compliance with Nasdaq’s listing requirements, but we can provide no assurance that any such action taken by 
us would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common 
stock from dropping below the Nasdaq minimum bid price requirement, or prevent future non-compliance with Nasdaq’s listing requirements. 

77

 
 
Because a small number of our existing stockholders own a majority of our voting stock, your ability to influence corporate matters will be limited. 

As of December 31, 2021, our executive officers, directors, and greater than 5% stockholders, in the aggregate, own approximately 29% of our 
outstanding common stock. As a result, such persons, acting together, will have the ability to control our management and business affairs and substantially 
all matters submitted to our stockholders for approval, including the election and removal of directors and approval of any significant transaction. This 
concentration of ownership may have the effect of delaying, deferring, or preventing a change in control, impeding a merger, consolidation, takeover, or 
other business combination involving us, or discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of our 
business, even if such a transaction would benefit other stockholders. 

If our shares become subject to the penny stock rules, it would become more difficult to trade our shares.

The SEC has adopted rules that regulate broker-dealer practices in connection with transactions in penny stocks. Penny stocks are generally equity 

securities with a price of less than $5.00, other than securities registered on certain national securities exchanges or authorized for quotation on certain 
automated quotation systems, provided that current price and volume information with respect to transactions in such securities is provided by the 
exchange or system. If we do not retain a listing on The Nasdaq Capital Market and if the price of our common stock is less than $5.00, our common stock 
will be deemed a penny stock. The penny stock rules require a broker-dealer, before a transaction in a penny stock not otherwise exempt from those rules, 
to deliver a standardized risk disclosure document containing specified information. In addition, the penny stock rules require that before effecting any 
transaction in a penny stock not otherwise exempt from those rules, a broker-dealer must make a special written determination that the penny stock is a 
suitable investment for the purchaser and receive (i) the purchaser’s written acknowledgment of the receipt of a risk disclosure statement; (ii) a written 
agreement to transactions involving penny stocks; and (iii) a signed and dated copy of a written suitability statement. These disclosure requirements may 
have the effect of reducing the trading activity in the secondary market for our common stock, and therefore stockholders may have difficulty selling their 
shares. 

We do not intend to pay dividends on our common stock and, consequently, your ability to achieve a return on your investment will depend on 
appreciation in the price of our common stock. 

We have never declared or paid any cash dividend on our common stock, and do not currently intend to do so for the foreseeable future. We 

currently anticipate that we will retain future earnings for the development, operation, and expansion of our business and do not anticipate declaring or 
paying any cash dividends for the foreseeable future. In addition, the Hercules Credit Facility currently prohibits, and any future debt financing 
arrangements may contain terms prohibiting or limiting the amount of, dividends that may be declared or paid on our common stock. Any return to 
stockholders will therefore be limited to the appreciation of their stock. Therefore, the success of an investment in shares of our common stock will depend 
upon any future appreciation in the value of our common stock. There is no guarantee that shares of our common stock will appreciate in value or even 
maintain the price at which our stockholders have purchased shares. 

A substantial number of shares of our common stock could be sold into the public market in the near future, which could depress our stock price. 

Sales of substantial amounts of our common stock in the public market could reduce the prevailing market prices for our common stock. 

Substantially all of our outstanding common stock is eligible for sale as is common stock issuable under vested and exercisable stock options. If our 
existing stockholders sell a large number of shares of our common stock, or the public market perceives that existing stockholders might sell shares of 
common stock, the market price of our common stock could decline significantly. Existing stockholder sales might also make it more difficult for us to sell 
additional equity securities at a time and price that we deem appropriate. 

78

 
We are a smaller reporting company, and we cannot be certain if the reduced reporting requirements applicable to smaller reporting companies will 
make our common stock less attractive to investors. 

We are a smaller reporting company under Rule 12b-2 of the Securities Exchange Act of 1934.  For as long as we continue to be a smaller reporting 

company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not smaller 
reporting companies, including reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements.  We cannot 
predict if investors will find our common stock less attractive because we may rely on smaller reporting company exemptions. If some investors find our 
common stock less attractive as a result, there may be a less active trading market for our common stock, and our stock price may be more volatile. 

We are incurring significant increased costs and demands upon management as a result of operating as a public company. 

As a public company, and particularly if and after we cease to be a “smaller reporting company,” we incur significant legal, accounting, and other 

expenses that we did not incur as a private company. We ceased to be an “emerging growth company,” as defined in the JOBS Act, on December 31, 2019. 
As a result, we expect to incur additional expenses and to devote increased management time toward ensuring compliance with those requirements 
applicable to companies that are not emerging growth companies. We are subject to the reporting requirements of the Securities Exchange Act of 1934, as 
amended, or the Exchange Act, which require, among other things, that we file with the Securities and Exchange Commission, or the SEC, annual, 
quarterly and current reports with respect to our business and financial condition. In addition, the Sarbanes-Oxley Act, as well as rules subsequently 
adopted by the SEC and Nasdaq to implement provisions of the Sarbanes-Oxley Act, imposes significant requirements on public companies, including 
requiring establishment and maintenance of effective disclosure and financial controls and changes in corporate governance practices. Further, in 2010, the 
Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, was enacted. There are significant corporate governance and 
executive compensation related provisions in the Dodd-Frank Act that require the SEC to adopt additional rules and regulations in these areas such as “say 
on pay” and proxy access. Stockholder activism, the current political environment, and the current high level of government intervention and regulatory 
reform may result in substantial new regulations and disclosure obligations, which may lead to additional compliance costs and impact the manner in which 
we operate our business in ways we cannot currently anticipate. 

We expect the rules and regulations applicable to public companies to continue to substantially increase our legal and financial compliance costs and 

to make some activities more time-consuming and costly. If public company rules and regulations divert the attention of our management and personnel 
from other business concerns, our business, financial condition, and results of operations could be adversely affected. Increased costs associated with public 
company expenses will decrease our net income or increase our net loss, and may require us to reduce costs in other areas of our business or increase the 
prices of our products or services. For example, public company rules and regulations make it more difficult and more expensive for us to obtain director 
and officer liability insurance, the cost of which has continued to rise in recent years, and thus we may be required to incur substantial costs to maintain the 
same or similar coverage. We cannot predict or estimate the amount or timing of additional 

79

 
costs we may incur to respond to these requirements, the impact of which could also make it more difficult for us to attract and retain qualified persons to 
serve on our board of directors, our board committees, or as executive officers. 

If we fail to maintain proper and effective internal control over financial reporting in the future, our ability to produce accurate and timely financial 
statements could be impaired, which could harm our operating results, investors’ views of us and, as a result, the value of our common stock. 

Pursuant to Section 404 of the Sarbanes-Oxley Act, our management is required to report upon the effectiveness of our internal control over 
financial reporting.  The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex 
and require significant documentation, testing, and possible remediation. To continue to comply with the requirements of being a reporting company under 
the Exchange Act, we will be required to continue to upgrade and maintain our systems including information technology; implement and maintain 
additional financial and management controls, reporting systems, and procedures; and hire additional accounting and finance staff. Furthermore, we rely on 
third-parties, including software and system providers, for ensuring our reporting obligations and effective internal controls, and to the extent these third 
parties fail to provide adequate service including as a result of any inability to scale to handle our growth and the imposition of these increased reporting 
and internal controls and procedures, we could incur material costs for upgrading or switching systems and our business could be materially affected. 

However, as a smaller reporting company and a non-accelerated filer and in accordance with new SEC rules effective in 2020, our independent 

registered public accounting firm will not be required to attest to the effectiveness of our internal control over financial reporting pursuant to Section 404 
for as long as we are not deemed an “accelerated filer” or “large accelerated filer.”

If we are unable to establish and maintain effective internal controls it could have a material adverse effect on our business, financial condition, 

results of operations or cash flows.

As we grow, we plan to hire additional personnel and engage in external temporary resources and may implement, document, and modify policies 

and procedures to maintain effective internal controls. However, we may identify deficiencies and weaknesses or fail to remediate previously identified 
deficiencies in our internal controls. If material weaknesses or deficiencies in our internal controls exist and go undetected or unremediated, our financial 
statements could contain material misstatements that, when discovered in the future, could cause us to fail to meet our future reporting obligations and 
cause the price of our common stock to decline.  In addition, we could be subject to sanctions or investigations by the SEC or other regulatory authorities, 
which would require additional financial and management resources.

If securities or industry analysts do not publish research or reports or publish unfavorable research or reports about our business, our stock price and 
trading volume could decline. 

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us, our 

business, our market, or our competitors. If one or more of the analysts who covers us downgrades our stock, our stock price would likely decline. If one or 
more of these analysts ceases to cover us or fails to regularly publish reports on us, interest in our stock could decrease, which could cause our stock price 
or trading volume to decline. 

80

 
 
Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us, which may be beneficial to our 
stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management. 

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws may delay or prevent an acquisition of us or a 

change in our management. These provisions include: 

•

•

•

•

•

•

•

authorizing the issuance of “blank check” preferred stock, the terms of which may be established and shares of which may be issued without 
stockholder approval; 

limiting the removal of directors by the stockholders; 

creating a staggered board of directors; 

prohibiting stockholder action by written consent, thereby requiring all stockholder actions to be taken at a meeting of our stockholders; 

eliminating the ability of stockholders to call a special meeting of stockholders; 

permitting our board of directors to accelerate the vesting of outstanding option grants upon certain transactions that result in a change of 
control; and 

establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted 
upon at stockholder meetings. 

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, 
which limits the ability of stockholders owning in excess of 15% of our outstanding voting stock to merge or combine with us. Although we believe these 
provisions collectively provide for an opportunity to obtain greater value for stockholders by requiring potential acquirors to negotiate with our board of 
directors, the provisions would apply even if an offer rejected by our board were considered beneficial by some stockholders. In addition, these provisions 
may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to 
replace members of our board of directors, which is responsible for appointing the members of our management. 

Our restated certificate of incorporation and amended and restated bylaws provide that the Court of Chancery of the State of Delaware and the federal 
district courts of the United States will be the exclusive forum 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 restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for any derivative 

action or proceeding brought on our behalf, any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the 
Delaware General Corporation Law, our certificate of incorporation or our bylaws or any action asserting a claim against us that is governed by the internal 
affairs doctrine. This provision would not apply to claims brought to enforce a duty or liability created by the Exchange Act or any other claim for which 
the federal courts have exclusive jurisdiction. Our amended and restated bylaws further provide that the federal district courts of the United States will be 
the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act.   These choices of 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 and may 
discourage these types of lawsuits. Furthermore, the enforceability of similar choice of forum provisions in other companies’ certificates of incorporation or 
bylaws has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable. 
While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in 
a venue other than those designated in the exclusive-forum provisions, and there can be no assurance that such provisions will be enforced by a court in 
those other jurisdictions. If a court were to find the exclusive-forum provision contained in our amended and restated certificate of incorporation to be 
inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our 
business.

81

 
 
 
We are subject to litigation risks. 

From time to time, we may become involved in various litigation matters and claims, including regulatory proceedings, administrative proceedings, 
governmental investigations, and contract disputes. We may face potential claims or liability for, among other things, breach of contract, defamation, libel, 
fraud, or negligence. We may also face employment-related litigation, including claims of age discrimination, sexual harassment, gender discrimination, 
immigration violations, or other local, state, and federal labor law violations. Because of the uncertain nature of litigation and insurance coverage decisions, 
the outcome of such actions and proceedings cannot be predicted with certainty and an unfavorable resolution of one or more of them could have a material 
adverse effect on our business, financial condition, results of operations, cash flows, and the trading price of our securities. In addition, legal fees and costs 
associated with prosecuting and defending litigation matters could have a material adverse effect on our business, financial condition, results of operations, 
and the trading price of our securities.

We could be subject to securities class action litigation. 

In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. The 

risk of securities class action litigation is especially relevant for us because biotechnology and pharmaceutical companies have experienced significant 
stock price volatility in recent years. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, 
which could harm our business. 

Our insurance policies are expensive and protect us only from some business risks, which leaves us exposed to significant uninsured liabilities. 

We do not carry insurance for all categories of risk that our business may encounter. Some of the policies we currently maintain include general 

liability, product and clinical trial liability, workers’ compensation, and directors’ and officers’ insurance. We do not know, however, if we will be able to 
maintain existing insurance with adequate levels of coverage. Any significant, uninsured liability may require us to pay substantial amounts, which would 
adversely affect our working capital and results of operations. 

U.S. federal income tax reform could adversely affect us. 

New legislation or regulation which could affect our tax burden could be enacted by any governmental authority. We cannot predict the timing or 

extent of such tax-related developments which could have a negative impact on our financial results. Additionally, we use our best judgment in attempting 
to quantify and reserve for these tax obligations. However, a challenge by a taxing authority, our ability to utilize tax benefits such as carryforwards or tax 
credits, or a deviation from other tax-related assumptions could have a material adverse effect on our business, results of operations, or financial conditions. 

Our business could be negatively affected as a result of the actions of activist stockholders. 

Proxy contests have been waged against many companies in the biotechnology industry over the last few years. We may be particularly vulnerable 

to activist stockholders due to fluctuations in our stock price. If faced with a proxy contest or other type of stockholder activism, we may not be able to 
respond successfully to the contest or dispute, which would be disruptive to our business. Even if we are successful, our business could be adversely 
affected by a proxy contest or stockholder dispute involving us or our partners because: 

•

•

•

responding to proxy contests and other actions by activist stockholders can be costly and time-consuming, disrupting operations and diverting 
the attention of management and employees; 

perceived uncertainties as to future direction may result in the loss of potential acquisitions, collaborations, or in-licensing opportunities, and 
may make it more difficult to attract and retain qualified personnel and business partners; and 

if individuals are elected to a board of directors with a specific agenda, it may adversely affect our ability to effectively and timely implement 
our strategic plan and create additional value for our stockholders.

These actions could cause our stock price to experience periods of volatility.

None. 

ITEM 2.    PROPERTIES 

Our offices are located in Lexington, Massachusetts. As of December 31, 2021, we had leased approximately 9,351 square feet of office space 

pursuant to leases that expire in 2023. Management believes that this office space is suitable and adequate to meet our anticipated near-term needs. We 
anticipate that following the expiration of the lease, additional or alternative space will be available at commercially reasonable terms. 

ITEM 3. LEGAL PROCEEDINGS 

From time to time, we may become subject to legal proceedings, claims, and litigation arising in the ordinary course of business. We currently are 
not a party to any threatened or pending material litigation and do not have contingency reserves established for any litigation liabilities. However, third 
parties might allege that we are infringing their patent rights or that we are otherwise violating their intellectual property rights, including trade names and 
trademarks. Such third parties may resort to litigation. We accrue contingent liabilities when it is probable that future expenditures will be made and such 
expenditures can be reasonably estimated.

Holders of Record 

As of December 31, 2021, there were 25 holders of record of our common stock. The actual number of stockholders is greater than this number of 
record holders and includes stockholders who are beneficial owners but whose shares are held in street name by brokers and other nominees. This number 
of holders of record also does not include stockholders whose shares may be held in trust by other entities. 

Dividends 

We have not declared or paid any cash dividends on our common stock since our inception. We do not plan to pay dividends in the foreseeable 

future. Under our credit facility, we have agreed not to pay any dividends so long as it has any outstanding obligations thereunder. We currently intend to 
retain all available funds and any future earnings, if any, for use in the operation of our business. Any future determination to declare cash dividends will be 
made at the discretion of our board of directors, subject to applicable laws, and will depend on our financial condition, results of operations, capital 
requirements, general business conditions and other factors that our board of directors may deem relevant, and subject to the restrictions contained in future 
financing instruments. Consequently, stockholders will need to sell shares of our common stock to realize a return on their investment, if any.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS 

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and 

the related notes appearing at the end of this annual report on Form 10-K. Some of the information contained in this discussion and analysis, including 
information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks, uncertainties and assumptions. 
You should read the “Risk Factors” and “Special Note Regarding Forward-Looking Statements” sections of this annual report on Form 10-K for a 
discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking 
statements contained in the following discussion and analysis. 

Overview 

We are a biotechnology company devoted to discovering and developing innovative therapies designed to treat immune-mediated diseases. Our lead 

product candidate, reproxalap, is a first-in-class treatment in late-stage development for dry eye disease (DED) and allergic conjunctivitis (AC). We have 
additional product candidates in development for autoimmune diseases and other immune-mediated diseases, as well as for proliferative vitreoretinopathy 
(PVR) and other retinal diseases. We currently intend to commercialize our products directly or through collaborations. None of our product candidates 
have been approved for sale in the United States or elsewhere.

Our lead product candidate reproxalap is a RASP (reactive aldehyde species) modulator that has demonstrated statistically significant and clinically 

relevant improvements across a number of Phase 2 and Phase 3 clinical trials in DED and AC when administered topically to the eye as an ophthalmic 
solution. Additionally, in a Phase 1 clinical trial, ADX-629, a first-in-class orally available RASP modulator, was well-tolerated and no treatment-related 
adverse events were observed.  Relative to subjects treated with placebo, reduction in the commonly described pro-inflammatory RASP malondialdehyde 
was observed in ADX-629 treated subjects.  A growing body of clinical evidence supports the potential and relevance of RASP modulation as a new and 
differentiated mechanism of action. We have discovered and are developing additional RASP modulator. The RASP modulator platform represents a 
unique and novel pharmacologic approach that, unlike almost all drugs in use today, does not directly inhibit or activate a particular protein but instead 
targets a family of small molecules that in turn affect the activity and structure of many proteins at once. RASP modulation, therefore, has the potential to 
down-regulate pro-inflammatory systems or groups of proteins, and may lead to multiple beneficial clinical effects while avoiding toxicity associated with 
single-target inhibition or activation.

As we continue to execute on our strategy of expanding our product candidate pipeline, we may license or acquire new immune-modulating 
approaches with novel therapeutic potential. In January 2019, we acquired Helio Vision, Inc. (Helio) and thereby obtained rights to ADX-2191,  a vitreous-
compatible methotrexate formulation for intraocular injection, a serious sight-threatening retinal disease with no approved treatment and primary 
vitreoretinal lymphoma (PVRL), a rare cancer with no approved treatment. In addition, in December 2016, we in-licensed ADX-1612, which inhibits the 
protein chaperome, a mechanistically differentiated approach for the potential treatment of inflammatory diseases.  In the future, we may enter into 
additional partnerships that facilitate the development and commercialization of our product candidates.

Since our incorporation, we have devoted substantially all of our resources to the preclinical and clinical development of our product candidates. 

Our ability to generate revenues largely depends upon our ability, alone or with others, to complete development of our product candidates to obtain 
regulatory approvals for and to manufacture, market, and sell our product candidates. The results of our operations will vary significantly from year-to-year 
and quarter-to-quarter, and depend on a number of factors, including risks related to our business and industry, risks relating to intellectual property and 
other legal matters, risks related to our common stock, and other risks that are detailed in the section of this annual report on Form 10-K entitled “Risk 
Factors". 

In December 2018, we entered into an Open Market Sale Agreement SM (2018 Jefferies Sales Agreement) with Jefferies LLC (Jefferies), as sales 

agent, pursuant to which we offered and sold, shares of our common stock, for aggregate sales proceeds of $50.0 million from time to time through 
Jefferies.  During the year ended December 31, 2020, we sold, at a volume-weighted average price of $4.62, an aggregate of 9.4 million shares of common 
stock 

85

 
and received $40.7 million after deducting commissions related to the 2018 Jefferies Sales Agreement and other offering costs.  As of December 31, 2020, 
we had sold the maximum allowable amount and no further sales may be made under the 2018 Jefferies Sales Agreement.

In March 2019, we entered into the Hercules Credit Facility, which provided for a term loan of up to $60.0 million, $15.0 million of which has been 

drawn-down as of December 31, 2021. In April 2021, the Hercules Credit Facility was amended to, among other things, increase the amount which may 
become available for draw-down prior to May 2023, subject to the satisfaction of certain conditions contained therein, from $10.0 million to $20.0 million. 
The Hercules Credit Facility contains customary affirmative and negative covenants and events of default. Affirmative covenants include, among others, 
covenants requiring us to maintain our legal existence and governmental approvals, deliver certain financial reports, and maintain insurance coverage. 
Negative covenants include, among others: restrictions on transferring any part of our business or intellectual property; incurring additional indebtedness; 
engaging in mergers or acquisitions; paying dividends or making other distributions; making investments; and creating other liens on our assets, in each 
case subject to customary exceptions. The Hercules Credit Facility, as amended, is described in Note 9 to the notes to the consolidated financial statements 
contained in this annual report on Form 10-K. As of December 31, 2021, $15.0 million was outstanding under the Hercules Credit Facility, and no 
additional amounts were available for borrowing.

In January 2021, we sold 7.9 million shares of our common stock in an underwritten public offering at $9.50 per share, for an aggregate gross cash 

purchase price of $74.7 million or proceeds of $70.0 million after underwriters’ discount, commissions, and other offering expenses.

In March 2021, we entered into an Open Market Sales Agreement SM (2021 Jefferies Sales Agreement) with Jefferies, as sales agent, pursuant to 

which we may offer and sell, from time to time through Jefferies, shares of common stock providing for aggregate sales proceeds of up to $100.0 million. 
We have no obligation to sell any shares under the 2021 Jefferies Sales Agreement, and could at any time suspend solicitations and offers under the 2021 
Jefferies Sales Agreement. No sales had been made pursuant to the 2021 Jefferies Sales Agreement as of December 31, 2021.

In May and June 2021, we sold an aggregate of 10.2 million shares of our common stock at a public offering price of $12.50 per share, in an 
underwritten public offering, for an aggregate gross cash purchase price of $127.8 million or proceeds of approximately $119.8 million after underwriters’ 
discount, commissions, and other offering expenses, which included the partial exercise of the underwriters' option to purchase additional shares.

We will need to raise additional capital in the form of debt or equity or through partnerships to fund additional development of our product 

candidates and, subject to regulatory approval, if any, the commercialization of our product candidates, and we may in-license, acquire, or invest in 
complementary businesses or products. In addition, as capital resources permit, we may augment or otherwise modify the clinical development plans 
described herein. However, any disruption in the capital markets caused by the COVID-19 pandemic could make any financing more challenging, and there 
can be no assurance that we will be able to raise capital on commercially reasonable terms or at all.

Our Agreement with Madrigal

We are developing ADX-1612 pursuant to a License Agreement with Madrigal Pharmaceuticals, Inc. (Madrigal), entered into on December 26, 

2016 (Madrigal Agreement). Pursuant to the Madrigal Agreement, we obtained an exclusive, worldwide license from Madrigal under certain patents and 
patent applications, and other licenses to intellectual property, to develop and commercialize Hsp90 inhibitors, including ADX-1612 (investigated in 
oncology under the name ganetespib), (collectively, Madrigal Agreement Products). We have agreed to use our commercially reasonable efforts to develop 
Madrigal Agreement Products.

86

 
 
In consideration for the rights licensed under the Madrigal Agreement, we paid Madrigal an upfront license fee of $250,000 and are obligated to 

make future regulatory and development and sales-dependent milestone payments to Madrigal of less than $340 million in the aggregate (over 80% of such 
amount being tied to our achievement of increasingly greater annual worldwide net sales milestones), as well as royalty payments to Madrigal at a rate 
which, as a percentage of net sales, is in the high single digits for products containing ADX-1612 and mid-single digits for any other Hsp90 inhibitor 
product. We are also obligated under the Madrigal Agreement to pay Madrigal a percentage of certain sublicense revenue that we receive in connection 
with entering into any sublicensing arrangements with any third parties, at a percentage rate which tiers downward from the mid-twenties to low-single 
digits based on the development stage of the product at the time of the sublicense.

The Madrigal Agreement will remain in effect until all payment obligations under the Madrigal Agreement expire. We may terminate the Madrigal 

Agreement in its entirety or on a Madrigal Agreement Product-by Madrigal Agreement Product basis with timely notice to Madrigal. Either party may 
terminate the Madrigal Agreement for uncured material breach by the other party or upon certain insolvency or bankruptcy proceedings involving the other 
party, both with timely notice to the other party. In addition, Madrigal has the right to terminate the Madrigal Agreement if we, our affiliates, or 
sublicensees interferes with, challenges the validity or enforceability of, opposes the extension of, or grant of a supplementary protection certificate with 
respect to any of our licensed patents under the Madrigal Agreement. In the event of an early termination of the Madrigal Agreement, all rights licensed 
and developed by us under the Madrigal Agreement may revert back to Madrigal. Each party has agreed to indemnify the other party for certain third party 
claims arising under the Madrigal Agreement.

Our Agreement with MEEI

We are developing ADX-2191 pursuant to an Exclusive License Agreement with Massachusetts Eye and Ear Infirmary (MEEI) originally entered 
into in July 2016 between MEEI and Helio Vision, Inc., as amended, (MEEI Agreement). We assumed the MEEI Agreement in connection with our 2019 
acquisition of Helio Vision.

Pursuant and subject to the MEEI Agreement, we obtained an exclusive, worldwide license from MEEI to develop and commercialize ADX-2191 

under certain patents and patent applications, and other licenses to intellectual property (MEEI Patent Rights). We have agreed to use our commercially 
reasonable efforts to develop ADX-2191 and to meet certain specified effort and achievement benchmarks by certain dates.

In consideration for the rights licensed under the MEEI Agreement, Helio Vision issued MEEI a number of shares of its preferred stock and Helio 

Vision agreed to pay non-creditable non-refundable license maintenance fees to MEEI of $15,000 on each of the second and third anniversary of the MEEI 
Agreement, $25,000 on each of the fourth and fifth anniversary of the MEEI Agreement and $35,000 on the sixth and each subsequent anniversary of the 
MEEI Agreement during the term of such agreement.  In addition, Helio Vision was obligated to make future sales-dependent milestone payments to MEEI 
of up to the low seven figures in the aggregate, as well as royalty payments to MEEI at a rate which, as a percentage of net sales, is in the low single digits 
for products that incorporate or use the MEEI Patent Rights in the United States and as a percentage in the low single digits for products that incorporate or 
use the MEEI Patent Rights outside the United States. We are also obligated under the MEEI Agreement to pay MEEI a percentage of certain sublicense 
revenue that we receive in connection with entering into any sublicensing arrangements with any third parties, at a percentage rate which tiers downward 
from low-double digits to mid-single digits based on the date of the sublicense.  Following our acquisition of Helio Vision, we became obligated to make 
any future payments owed under the MEEI Agreement.  There is no additional equity consideration issuable under the MEEI Agreement.

The MEEI Agreement will remain in effect until the expiration date of the last to expire patent licensed under the MEEI Agreement.   We may 

terminate the MEEI Agreement with timely written notice to MEEI. MEEI has the right to terminate the MEEI Agreement if we, subject to certain 
specified cure periods, cease all business operations with respect to licensed products, fail to pay amounts due under the MEEI Agreement, fail to comply 
with certain due diligence obligations, default in our obligation to maintain insurance, one of our officers is convicted of a felony 

87

 
relating to the manufacture, use, sale or importation of licensed products, we materially breach any provisions of the MEEI Agreement or in the event of 
our insolvency or bankruptcy.

In the event of an early termination of the MEEI Agreement, all rights licensed and developed by us under the MEEI Agreement may revert back to 

MEEI. We have agreed to indemnify MEEI for certain claims that may arise under the MEEI Agreement.

Our Acquisition of Helio Vision, Inc.

On January 28, 2019, we acquired Helio. Upon the closing of the acquisition, we issued an aggregate of 1,160,444 shares of common stock to the 

former securityholders and an advisor of Helio. In January 2021, pursuant to the terms of the acquisition agreement, we issued an additional 246,562 shares 
of common stock to the former securityholders of Helio. Subject to the conditions of the acquisition agreement, we are contingently obligated to make 
additional payments to the former securityholders of Helio as follows: (a) $10.0 million of common stock following approval by the FDA of a new drug 
approval application for the prevention and/or treatment of PVR or a substantially similar label prior to the 10th anniversary of the closing date; and (b) 
$2.5 million of common stock following FDA of a new drug approval application for an indication (other than PVR or a substantially similar label) prior to 
the 12th anniversary of the closing date, provided that in no event shall we be obligated to issue more than 5,248,885 shares of common stock in the 
aggregate. Additionally, in the event of certain change of control or divestitures by us, certain former convertible noteholders of Helio will be entitled to a 
tax gross-up payment in an amount not to exceed $1.0 million.

Research and development expenses 

We expense all of our research and development expenses as they are incurred. Research and development costs that are paid in advance of 

performance are capitalized as a prepaid expense until incurred. Research and development expenses primarily include: 

•

•

•

non-clinical development, preclinical research, and clinical trial and regulatory-related costs; 

expenses incurred under agreements with sites and consultants that conduct our clinical trials; and 

employee-related expenses, including salaries, benefits, travel, and stock-based compensation expense. 

Substantially all of our research and development expenses to date have been incurred in connection with reproxalap. We expect our research and 

development expenses to increase for the foreseeable future as we advance reproxalap and other compounds through preclinical and clinical development. 
The process of conducting clinical trials necessary to obtain regulatory approval is costly and time consuming. We are unable to estimate with any certainty 
the costs we will incur in the continued development of reproxalap and our other product candidates. Clinical development timelines, the probability of 
success, and development costs can differ materially from expectations. We may never succeed in achieving marketing approval for our product candidates. 

The costs of clinical trials may vary significantly over the life of a project owing to, but not limited to, the following: 

•

•

•

•

•

•

•

per patient trial costs; 

the number of sites included in the trials; 

the countries in which the trials are conducted; 

delays of, or other effects on, clinical trials resulting from the ongoing COVID-19 pandemic or for other reasons;

the length of time required to enroll eligible patients; 

the design of the trials; 

the cost of drug manufacturing; 

88

 
•

•

•

•

•

•

•

•

•

the number of patients that participate in the trials; 

the number of doses that patients receive; 

the costs of assay development, assays, or other assessment of clinical trial endpoints;

the cost of vehicle or active comparative agents used in trials; 

the drop-out or discontinuation rates of patients; 

potential additional safety monitoring or other studies requested by regulatory agencies; 

the duration of patient follow-up; 

the phase of development the product candidate is in; and 

the efficacy and safety profile of our product candidates. 

Included in research and development are expenses associated with asset acquisitions. Assets purchased in an asset acquisition transaction are 
expensed as in-process research and development unless the assets acquired are deemed to have an alternative future use. Acquired in-process research and 
development payments are immediately expensed, and include upfront payments, as well as transaction fees and subsequent milestone payments. 
Development costs incurred after the asset acquisition are expensed as incurred. 

We do not expect reproxalap or any of our other product candidates to be commercially available, if at all, before at least 2023. 

General and administrative expenses 

Our general and administrative expenses consisted primarily of employee-related expenses, including benefits and stock-based compensation for our 
full-time employees during the years ended December 31, 2021 and 2020. Other general and administrative expenses include professional fees for auditing, 
tax, and legal services, including patent related costs. We expect that general and administrative expenses will increase in the future as we expand our 
operating activities, continue to incur additional costs associated with being a publicly-traded company, and maintain compliance with exchange listing and 
SEC requirements. These increases will likely include higher consulting costs, legal fees, accounting fees, directors’ and officers’ liability insurance 
premiums, and fees associated with investor relations. 

Other income (expense) 

Total other income (expense) consists primarily of interest income we earn on interest-bearing accounts, and interest expense incurred on our 

outstanding debt. 

Comprehensive loss 

Comprehensive loss is defined as the change in equity during a period from transactions and other events and/or circumstances from non-owner 

sources. For the year ended December 31, 2021, comprehensive loss is equal to our net loss of $57.8 million and no unrealized loss on marketable 
securities. For the year ended December 31, 2020, comprehensive loss is equal to our net loss of $37.6 million and a realized loss on marketable securities 
of $5.9 thousand.

Critical Accounting Estimates 

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which we have 

prepared in accordance with generally accepted accounting principles in the United States (US GAAP). The preparation of these financial statements 
requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities 
at the date of the financial statements, as well as the expenses during the reported periods. We evaluate these estimates and judgments on an ongoing basis. 
We base our estimates on historical experience and on various 

89

 
other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of 
assets and liabilities that are not readily apparent from other sources. Our actual results may differ materially from these estimates under different 
assumptions or conditions. 

While our significant accounting policies are more fully described in Note 2 to our financial statements appearing elsewhere in this annual report on 

Form 10-K, we believe that the following accounting policies are the most critical in order to fully understand and evaluate our financial condition and 
results of operations. 

Accrued Research and Development Expenses 

As part of the process of preparing financial statements, we are required to estimate and accrue research and development expenses. This process 

involves the following: 

•

•

•

communicating with our applicable personnel to identify services that have been performed on our behalf and estimating the level of service 
performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual cost; 

estimating and accruing expenses in our financial statements as of each balance sheet date based on facts and circumstances known to us at 
the time; and 

periodically confirming the accuracy of our estimates with selected service providers and making adjustments, if necessary. 

Examples of estimated research and development expenses that we accrue include: 

•

•

•

fees paid to investigative sites in connection with clinical studies; 

fees paid to contract manufacturing organizations in connection with non-clinical development, preclinical research, and the production of 
clinical study materials; and 

professional service fees for consulting and related services. 

We base our expense accruals related to non-clinical development, preclinical studies, and clinical trials on our estimates of the services received 
and efforts expended pursuant to contracts with organizations/consultants that conduct and manage clinical studies on our behalf. The financial terms of 
these agreements vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts may depend on many 
factors, such as the successful enrollment of patients, site initiation, and the completion of clinical study milestones. Our service providers invoice us 
monthly in arrears for services performed. In accruing service fees, we estimate the time period over which services will be performed and the level of 
effort to be expended in each period. If we do not identify costs that we have begun to incur, or if we underestimate or overestimate the level of services 
performed or the costs of these services, our actual expenses could differ from our estimates. To date, we have not experienced significant changes in our 
estimates of accrued research and development expenses after a reporting period. However, due to the nature of estimates, we cannot assure you that we 
will not make changes to our estimates in the future as we become aware of additional information about the status or conduct of our clinical trials and 
other research activities. 

COVID-19

We are closely monitoring the impact of the COVID-19 pandemic, including the emergence and spread of variants of COVID-19, on all aspects of 

our business, including how the pandemic continues to impact our employees, clinical trials, development programs, supply chain, and other aspects of our 
operations.  For example, patient enrollment in our GUARD trial was negatively impacted as a result of limited clinical trial staffing at study sites and some 
patients electing to delay surgery.  While the COVID-19 pandemic did not have a material adverse effect on our reported results for the year ended 
December 31, 2021, we are unable to predict the ultimate impact that the pandemic may have on our business, future results of operations, financial 
position, or cash flows. The extent to which our operations may be impacted by the COVID-19 pandemic will depend largely on future developments, 
which are highly uncertain and cannot be accurately predicted, including new information which may emerge concerning the severity of the outbreak, 
including the emergence and spread of variants of COVID-19, and 

90

 
 
actions by government authorities to contain the outbreak. Furthermore, the impact of a potential worsening of global economic conditions and the effects 
of continued disruptions to and volatility in the financial markets remains unknown.

Other Information 

Net Operating Loss Carryforwards 

As of December 31, 2021, we had federal and state income tax net operating loss (NOL) carryforwards of approximately $226.0 million and $219.0 
million, respectively. Federal NOL carryforwards generated through December 31, 2017 and state NOL carryforwards will expire at various dates through 
2041. Federal NOLs generated during the years ended December 31, 2018 and thereafter will carry forward indefinitely.  As of December 31, 2021, we had 
federal and state research and development tax credit carryforwards of approximately $6.9 million and $1.6 million, respectively, which will expire at 
various dates through 2041. Additionally, as of December 31, 2021, we had a federal orphan drug tax credit carryforward of approximately $1.0 million 
that expires in 2041.

Future changes in federal and state tax laws pertaining to net operating loss carryforwards may also cause limitations or restrictions from us 
claiming such net operating losses. If the net operating loss carryforwards become unavailable to us or are fully utilized, our future taxable income will not 
be shielded from federal and state income taxation absent certain U.S. federal and state tax credits, and the funds otherwise available for general corporate 
purposes would be reduced.

Under Section 382 of the Internal Revenue Code of 1986, as amended, a corporation that undergoes an “ownership change” is subject to limitations 

on its ability to utilize its pre-change NOLs and certain other tax assets (tax attributes) to offset future taxable income. In general, an ownership change 
occurs if the aggregate stock ownership of certain stockholders increases by more than 50 percentage points over such stockholders’ lowest percentage 
ownership during the testing period (generally three years). Transactions involving our common stock within the testing period, even those outside our 
control such as purchases or sales by investors, could result in an ownership change. A limitation on our ability to utilize some or all our NOLs or credits 
could have a material adverse effect on our results of operations and cash flows. We believe, prior to December 31, 2020 that three ownership changes 
occurred since inception, and that a fourth ownership change was triggered during the year ended December 31, 2021.  Management believes that its 
aggregate Section 382 limitation (including the additional limitation for recognized "built-in gains") is sufficient so that no current impairment of its pre-
ownership change tax attributes is required.  Any future ownership changes, including those resulting from our recent or future financing activities, may 
cause our existing tax attributes to have additional limitations. 

Recent Accounting Pronouncements

Recent accounting pronouncements which may be applicable to us are described in Note 2 to our Consolidated Financial Statements included in the 

annual report on Form 10-K.

Results of Operations 

We anticipate that our results of operations will fluctuate for the foreseeable future due to several factors, including the progress of our research and 

development efforts, the timing and outcome of clinical trials, and regulatory requirements. Our limited operating history makes predictions of future 
operations difficult or impossible. Since our inception, we have incurred significant losses. 

Comparison of Years Ended December 31, 2021 and 2020 

Net loss. Net loss for the years ended December 31, 2021 and 2020 was approximately $57.8 million and $37.6 million, respectively. As of 
December 31, 2021, we had total stockholders’ equity of $205.7 million. Losses have resulted principally from costs incurred in our clinical trials and other 
research and development programs, amortization costs of founders’ stock related to the acquisition of Helio in January 2019, and from our general and 
administrative expenses. 

91

 
 
Research and development expenses. Research and development expenses were $44.9 million for the year ended December 31, 2021 compared to 

$24.7 million for the same period in 2020. The increase of $20.2 million is primarily related to an increase in our external research and development 
expenditures based on planned clinical activities, partially offset by decreases in personnel related costs and $1.2 million in non-cash compensation costs in 
2020 related to a portion of a contingent milestone in the Helio agreement that was recognized at December 31, 2020 and was settled in the first quarter of 
2021.

General and administrative expenses. General and administrative expenses were $11.3 million for the year ended December 31, 2021, compared to 

$10.0 million for the year ended December 31, 2020. The increase of approximately $1.3 million is primarily related to increases in legal expenses, 
insurance costs, and consulting fees.

Acquired in-process research and development expenses. Acquired in-process research and development expenses were nil for the year ended 
December 31, 2021, compared to $1.8 million for the year ended December 31, 2020. The $1.8 million recorded during the year ended December 31, 2020 
of in-process research and development expenses was associated with the January 2019 acquisition of Helio. At December 31, 2020, a contingent milestone 
related to Helio was determined to be probable and estimable, and we recorded $1.8 million of acquired in-process research and development expense 
related to a portion of the non-cash compensation costs that occurred as a result of the contingent milestone, which was settled in the first quarter of 2021.

Other income (expense). Total other income (expense) was approximately ($1.6) million for the year ended December 31, 2021, compared to ($1.6) 

million for the year ended December 31, 2020.  Total other income (expense), for both periods, was principally comprised of interest income and interest 
expense.

Liquidity and Capital Resources 

We have funded our operations primarily from the sale of equity securities and convertible equity securities and borrowings under credit facilities. 

Since inception, we have incurred operating losses and negative cash flows from operating activities and have devoted substantially all our efforts to 
research and development. At December 31, 2021, we had total stockholders’ equity of approximately $205.7 million and cash and cash equivalents of 
$229.8 million. During the year ended December 31, 2021, we had net loss of approximately $57.8 million. We expect to generate operating losses for the 
foreseeable future. 

In December 2018, we entered into an Open Market Sale Agreement SM (2018 Jefferies Sales Agreement) with Jefferies LLC (Jefferies), as sales 

agent, pursuant to which we offered and sold, shares of our common stock for aggregate sales proceeds of $50.0 million from time to time through 
Jefferies. From January 1, 2020 through December 31, 2020, we sold, at a volume-weighted average price of $4.62, an aggregate of 9.4 million shares of 
common stock with net proceeds of $40.7 million after deducting commissions related to the 2018 Jefferies Sales Agreement and other offering costs. As of 
December 31, 2020, we had sold the maximum allowable amount and no further sales may be made under the 2018 Jefferies Sales Agreement.

In January 2021, we closed an underwritten public offering in which we sold an aggregate of 7.9 million shares of common stock at $9.50 per share. 

The net proceeds of the offering were approximately $70.0 million, after deducting underwriting discounts, commissions, and other offering expenses. 

In March 2021, we entered into an Open Market Sales Agreement SM (2021 Jefferies Sales Agreement) with Jefferies, as sales agent, pursuant to 

which we may offer and sell, from time to time through Jefferies, shares of common stock providing for aggregate sales proceeds of up to $100.0 million. 
We have no obligation to sell any shares under the 2021 Jefferies Sales Agreement, and could at any time suspend solicitations and offers under the 2021 
Jefferies Sales Agreement. No sales had been made pursuant to the 2021 Jefferies Sales Agreement as of December 31, 2021.

In May and June 2021, we sold an aggregate of 10.2 million shares of our common stock at a public offering price of $12.50 per share, in an 
underwritten public offering, for an aggregate gross cash purchase price of $127.8 million or proceeds of approximately $119.8 million after underwriters’ 
discount, commissions, and other offering expenses, which included the partial exercise of the underwriters' option to purchase additional shares.

92

 
 
  
  
In March 2019, we entered into the Hercules Credit Facility (Loan and Security Agreement), pursuant to which a term loan of up to an aggregate 
principal amount of $60.0 million may be made available to us. The Loan and Security Agreement provides for (i) an initial term loan advance of up to 
$5.0 million at our option, which expired unutilized on April 15, 2019; (ii) three additional term loan advances of up to $15.0 million each, at our option, 
available to us upon the occurrence of certain funding conditions prior to September 30, 2019 (2019 Tranche), March 31, 2020 (2020 Tranche), and March 
31, 2021 (2021 Tranche); and (iii) a final additional term loan advance (Fourth Loan Tranche) of up to $10.0 million prior to December 31, 2021, at our 
option, subject to approval by Lender’s investment committee. We drew down the 2019 Tranche in full in September 2019 and the 2020 Tranche and the 
2021 Tranche expired unutilized prior to us satisfying the funding conditions for such tranche. On April 20, 2021, we entered into the First Amendment 
(First Amendment) to Loan and Security Agreement with Hercules. The First Amendment among other things, (i) increased the Fourth Loan Tranche from 
$10.0 million to $20.0 million and extended the deadline for drawing down the Fourth Loan Tranche to July 1, 2022; (ii) lowered the variable per annum 
rate of interest on borrowings under the Loan and Security Agreement to the greater of (a) the Prime Rate plus 3.10% or (b) 8.60%; (iii) extended the 
expiration of the period in which interest-only payments on borrowings under the Loan and Security Agreement are required from May 1, 2021 to July 1, 
2022; and (iv) following the satisfaction of certain conditions in April 2021, further extended the expiration of the interest-only period and the deadline for 
drawing down the Fourth Loan Tranche to May 1, 2023.  As of December 31, 2021, we had not satisfied the funding conditions for the Fourth Loan 
Tranche.

The Loan and Security Agreement contains customary affirmative and negative covenants and events of default. Affirmative covenants include, 

among others, covenants requiring us to maintain our legal existence and governmental approvals, deliver certain financial reports, and maintain insurance 
coverage. Negative covenants include, among others: restrictions on transferring any part of our business or intellectual property; incurring additional 
indebtedness; engaging in mergers or acquisitions; paying dividends or making other distributions; making investments; and creating other liens on our 
assets, in each case subject to customary exceptions. As of December 31, 2021, $15.0 million was outstanding under the Hercules Credit Facility, and no 
additional amounts were available for borrowing. 

Following the effective time of the First Amendment, an aggregate of $35.0 million, subject to the terms and conditions of the Loan and Security 

Agreement, may be made available to us for borrowing, $15.0 million of which was funded prior to the date of the First Amendment. 

Based on our current operating plan, we believe that our cash and cash equivalents, as of December 31, 2021,  will be sufficient to fund our 
currently projected operating expenses through the end of 2023, including potential NDA submissions; initial commercialization of reproxalap, if 
approved; and continued early and late-stage development of our product candidates in ocular and systemic immune-mediated diseases. We will need to 
secure additional funding in the future, from one or more equity or debt financings, collaborations, or other sources, in order to carry out all of our planned 
research and development activities, commercialize our product candidates, or conduct any substantial additional development requirements requested by 
the FDA. At this time, due to the risks inherent in the drug development process, we are unable to estimate with any certainty the costs we will incur in the 
continued clinical development of reproxalap and our other product candidates. Subsequent trials initiated at a later date will cost considerably more, 
depending on the results of our prior clinical trials, and feedback from the FDA or other third parties. Accordingly, we will continue to require substantial 
additional capital to continue our clinical development and potential commercialization activities. The amount and timing of our future funding 
requirements will depend on many factors, including but not limited to:

•

•

•

the progress, costs, results, and timing of our clinical development program for reproxalap and our other product candidates, including our 
current and planned clinical trials; 

the need for, and the progress, costs, and results of, any additional clinical trials of reproxalap or our other product candidates that we may 
initiate based on the results of our planned clinical trials or discussions with the FDA, including any additional trials the FDA or other 
regulatory agencies may require evaluating the efficacy and safety of reproxalap and our other product candidates; 

the impact of the COVID-19 pandemic on clinical trial initiation and enrollment and other aspects of our business, results of operations, and 
financial position;

93

 
 
 
 
•

•

•

•

•

•

•

•

the outcome, costs, and timing of seeking and obtaining regulatory approvals from the FDA, and any similar regulatory agencies; 

the timing and costs associated with manufacturing reproxalap and our other product candidates for clinical trials and other studies and, if 
approved, for commercial sale; 

our need and ability to hire additional management, development, and scientific personnel; 

the cost to maintain, expand, and defend the scope of our intellectual property portfolio, including the amount and timing of any payments we 
may be required to make, or that we may receive, in connection with licensing, filing, prosecuting, defending, and enforcing of any patents or 
other intellectual property rights; 

the timing and costs associated with establishing sales and marketing infrastructure; 

market acceptance of reproxalap and our other product candidates; 

the costs of acquiring, licensing, or investing in additional businesses, products, product candidates, and technologies; and 

our need to implement additional internal systems and infrastructure, including financial and reporting systems. 

We may need or desire to obtain additional capital to finance our operations through debt, equity, or alternative financing arrangements. We may 

also seek capital through collaborations or partnerships with other companies. The issuance of debt could require us to grant additional liens on certain of 
our assets that may limit our flexibility. If we raise additional capital by issuing equity securities, the terms and prices for these financings may be much 
more favorable to the new investors than the terms obtained by our existing stockholders. These financings also may significantly dilute the ownership of 
our existing stockholders.  In addition, the disruption in the capital markets caused by the COVID-19 pandemic could make any financing more 
challenging, and there can be no assurance that we will be able to obtain such financing on commercially reasonable terms or at all. If we are unable to 
obtain additional financing, we may be required to reduce the scope of our future activities, which could harm our business, financial condition, and 
operating results. There can be no assurance that any additional financing required in the future will be available on acceptable terms, if at all. 

We will continue to incur costs as a public company including, but not limited to, costs and expenses for directors fees; increased directors and 
officers insurance; investor relations fees; expenses for compliance with the Sarbanes-Oxley Act of 2002 and related to rules implemented by the SEC and 
Nasdaq, on which our common stock is listed; and various other costs. The Sarbanes-Oxley Act of 2002 requires that we maintain effective disclosure 
controls and procedures and internal controls. The following table summarizes our cash flows for the years ended December 31, 2021 and 2020:

Operating Activities. Net cash used in operating activities was $42.6 million in 2021, compared to net cash used in operating activities of $37.5 

million in 2020. The primary use of cash was to fund our operations. The increase in the amount of cash used in operating activities for 2021 as compared 
to 2020 was primarily due to the timing of payments for research and development expenses in both years and higher research and development expenses 
in 2021.

Investing Activities. Net cash (used in) provided by investing activities in 2021 was ($7.8) thousand, related primarily to purchases of fixed assets. 
Net cash provided by investing activities in 2020 of $29.0 million, related primarily to the sales and maturities of marketable securities partially offset by 
the purchase of marketable securities.

Financing Activities. Net cash provided by financing activities was $194.5 million for the year ended December 31, 2021, related primarily to the 

January and May 2021 public offerings, under which we sold an aggregate of 18.1 million shares of our common stock with net proceeds of $189.8 million 
after deducting commissions and other offering costs. In addition, we received $4.6 million from the proceeds from the exercise of stock options during 
2021.  Net cash provided by financing activities of $41.9 million for year ended 2020, related primarily the 2018 Jefferies Sales Agreement, under which 
we sold an aggregate of 9.4 million shares of our common stock resulting in $40.7 million in net proceeds after deducting commissions and other offering 
costs, and proceeds from the exercise of stock options.

Off-Balance Sheet Arrangements. Through December 31, 2021, we have not entered into and did not have any relationships with unconsolidated 

entities or financial collaborations, such as entities often referred to as structured finance or special purpose entities, which would have been established for 
the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purpose. 

Contractual Obligations and Commitments. We are a smaller reporting company as defined by Rule 12b-2 of the Securities Exchange Act of 1934 

and are not required to provide the information under this item.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

Interest rates 

Our exposure to market risk is currently confined to our cash, our cash equivalents, our marketable securities (if any) and our Hercules Credit 
Facility. We have not used derivative financial instruments for speculation or trading purposes. Because of the short-term maturities of our cash, cash 
equivalents and marketable securities, we do not believe that an increase in market rates would have any significant impact on the realized value of our 
investments. Our Hercules Credit Facility accrues interest from its date of issue at a variable annual interest rate equal to the greater of (i) 8.60% and (ii) 
the prime rate (as reported in the Wall Street Journal or any successor publication thereto) plus 3.10%. As of December 31, 2021, $15.0 million was 
outstanding under the Hercules Credit Facility.

Effects of inflation 

Inflation has not had a material impact on our results of operations.

ITEM 9A. 

CONTROLS AND PROCEDURES 

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures 

As of the end of the period covered by this annual report on Form 10-K, we carried out an evaluation under the supervision and with the 

participation of our Disclosure Committee and our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness 
of the design and operation of our disclosure controls and procedures pursuant to Exchange Act Rules 13a-15(e) and 15d-15(e). Disclosure controls are 
procedures that are designed to ensure that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934, or the 
Exchange Act, such as this annual report on Form 10-K, is recorded, processed, summarized, and reported within the time periods specified by the United 
States Securities and Exchange Commission. Disclosure controls are also designed to ensure that such information is accumulated and communicated to 
our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required 
disclosure. Our quarterly evaluation of disclosure controls includes an evaluation of some components of our internal control over financial reporting. We 
also perform a separate annual evaluation of internal control over financial reporting for the purpose of providing the management report below. 

The evaluation of our disclosure controls included a review of their objectives and design, our implementation of the controls and the effect of the 

controls on the information generated for use in this annual report on Form 10-K. In the course of the control evaluations, we reviewed data errors or 
control problems identified and sought to confirm that appropriate corrective actions, including process improvements, were being undertaken. This type of 
evaluation is performed on a quarterly basis so that the conclusions of management, including our Chief Executive Officer and our Chief Financial Officer, 
concerning the effectiveness of the disclosure controls can be reported in our periodic reports on Form 10-Q and Form 10-K. The overall goals of our 
evaluation activities are to monitor our disclosure controls and to modify them as necessary. We intend to maintain our disclosure controls as dynamic 
processes and procedures that we adjust as circumstances merit. 

Based on our management’s evaluation (with the participation of our Chief Executive Officer and our Chief Financial Officer), as of the end of the 

period covered by this report, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures were 
effective. 

Management’s Report on Internal Control over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 

15d-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting 
principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any 
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree 
of compliance with the policies or procedures may deteriorate. 

96

 
Our management utilized the criteria established in the Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO) to conduct an assessment of the effectiveness of our internal control over financial reporting as of 
December 31, 2021. Based on the assessment, our management has concluded that, as of December 31, 2021, our internal control over financial reporting 
was effective. 

Attestation Report on Internal Control over Financial Reporting

This annual report on Form 10-K does not include an attestation report of our independent registered public accounting firm due to the deferral 

allowed given we are neither an accelerated or large accelerated filer.

Changes in Internal Control over Financial Reporting 

There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during 

the fourth quarter of  2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Stockholders and Board of Directors 
Aldeyra Therapeutics, Inc. 
Lexington, Massachusetts 

Opinion on the Consolidated Financial Statements 

We have audited the accompanying consolidated balance sheets of Aldeyra Therapeutics, Inc. and subsidiaries (the “Company”) as of December 31, 
2021 and 2020, the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows for each of the two years in the 
period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated 
financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of their 
operations and their cash flows for each of the two years in the period ended December 31, 2021, in conformity with accounting principles generally 
accepted in the United States of America.  

Basis for Opinion 

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the 

Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting 
Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities 
laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain 
reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is 
not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to 
obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s 
internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error 

or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and 
disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by 
management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis 
for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was 

communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated 
financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not 
alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, 
providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Accrual for Research and Development Costs Related to Clinical Trial Activities

As described in Note 2 and disclosed in Note 8 to the consolidated financial statements, the Company’s accrued research and development costs 

balance was $8.4 million at December 31, 2021.  This accrual includes liabilities for clinical trial activities including clinical studies. Clinical studies are 
primarily managed internally, with 

106

 
 
the assistance of third-party service providers, including contract research organizations. The accrual for clinical trial activities is based on an estimate of 
the percentage of activities completed to date, contractual rates, and amounts invoiced and paid to date.  

We identified the assessment of the accrual for research and development costs related to clinical trial activities as a critical audit matter. The 
determination of the percentage of activities completed to date requires subjective estimates based on discussions with and reports provided by the contract 
research organizations, oversight of the activities, and the overall project budgets. Testing of the estimates required a higher degree of auditor judgment to 
evaluate and changes to the estimates could have a significant impact on the amount of accrued clinical trial expenses recorded by the Company.

The primary procedures we performed to address this critical audit matter included:

•

•

•

Evaluating management’s process for estimating the accrual for clinical trial activities including estimating the activities completed to date and the 
associated cost incurred for the clinical trial activities.

For certain contract research organizations, we tested the completeness and accuracy of the underlying billing information received from the contract 
research organizations used in determining the clinical trial accrual, including corroborating with invoices received and payments made by the 
Company to the contract research organizations.

For certain clinical trial studies, we assessed the Company's estimates of the activities completed to date by (i) inspecting original contract terms and 
change orders including the expected timeline for the related study, (ii) obtaining third party reports detailing site visit information, and (iii) confirming 
clinical trial progress directly with the contract research organizations and comparing the reported amounts to the Company's estimates.

/s/ BDO USA, LLP 

We have served as the Company’s auditor since 2013.

Basis of Presentation – The accompanying consolidated financial statements were prepared in conformity with accounting principles generally 

accepted in the United States of America (US GAAP). 

Risks and Uncertainties –The ongoing research and development activities will be subject to extensive regulation by numerous governmental 
authorities in the United States. Prior to marketing in the United States, any drug developed by the Company must undergo rigorous preclinical and clinical 
testing and an extensive regulatory approval process implemented by the United States Food and Drug Administration (FDA) under the Food, Drug and 
Cosmetic Act. The Company has limited experience in conducting and managing the preclinical and clinical testing necessary to obtain regulatory 
approval. There can be no assurance that the Company will not encounter problems in the clinical trials that will cause the Company or the FDA to delay or 
suspend clinical trials. 

The Company’s success will depend in part on its ability to obtain patents and product license rights, maintain trade secrets, and operate without 

infringing on the property rights of others, both in the United States and other countries. There can be no assurance that patents issued to or licensed by the 
Company will not be challenged, invalidated, circumvented, or that the rights granted thereunder will provide proprietary protection or competitive 
advantages to the Company. 

Based on its current operating plan, the Company believes that its cash and cash equivalents  as of December 31, 2021, will be sufficient to fund the 

Company's currently projected operating expenses through the end of 2023,  including potential new drug application (NDA) submissions; initial 
commercialization of reproxalap, if approved; and continued early and late-stage development of our product candidates in ocular and systemic immune-
mediated diseases.  As a result of the COVID-19 pandemic, clinical site availability, staffing, and patient recruitment have been negatively affected and the 
timelines to complete the Company’s clinical trials may be delayed. The Company’s assessment of its liquidity and capital resources includes an estimate of 
the financial impacts of these changes. The Company will need to secure additional funding in the future, from one or more equity or debt financings, 
collaborations, or other sources, in order to carry out all of the Company’s planned research and development activities and regulatory activities; 
commercialize product candidates; or conduct any substantial, additional development requirements requested by the Food and Drug Administration 
(FDA). Additional funding may not be available to the Company on acceptable terms, or at all. If the Company is unable to secure additional capital, it will 
be required to significantly decrease the amount of planned expenditures and may be required to cease operations.

Curtailment of operations would cause significant delays in the Company’s efforts to develop and introduce its products to market, which is critical 

to the realization of its business plan and the future operations of the Company. 

Use of Estimates – The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and 
assumptions, including fair value estimates for investments that affect the reported amounts of assets, liabilities, and the disclosure of contingent assets and 
liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. The Company 

113

 
evaluates its estimates and assumptions on an ongoing basis. The most significant estimates in the Company’s financial statements include, but are not 
limited to, estimates related to clinical trial accruals, estimates related to deferred and accrued research and development costs, and accounting for income 
taxes and the related valuation allowance. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake 
in the future, actual results may materially differ from these estimates and assumptions. 

Segment Information – Operating segments are defined as components of an enterprise about which separate discrete information is available for 

evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The 
Company views its operations and manages its business in one segment, which is the identification and development of next-generation medicines to 
improve the lives of patients with immune-mediated diseases. 

Cash and Cash Equivalents – The Company classifies all highly liquid investments with original maturities of three months or less as cash 
equivalents and all highly liquid investments with original maturities of greater than three months but less than 12 months as current marketable securities. 
The Company has a policy of making investments only with commercial institutions that have at least an investment grade credit rating. The Company 
invests its cash primarily in reverse repurchase agreements (RRAs), government securities and obligations, and money market funds. 

RRAs are collateralized by deposits in the form of ‘Government Securities and Obligations’ for an amount not less than 102% of their value. The 

Company does not record an asset or liability related to the collateral as the Company is not permitted to sell or repledge the associated collateral. The 
Company has a policy that the collateral has at least an A (or equivalent) credit rating. The Company utilizes a third-party custodian to manage the 
exchange of funds as well as the requirement that collateral received is maintained at 102% of the value of the RRAs on a daily basis.  

Marketable Securities – Marketable securities consist of government securities and obligations with original maturities of more than 90 days. 

Investments are classified as available-for-sale and are recorded on the balance sheet at fair value with unrealized gains or losses reported as a separate 
component of other comprehensive income/(loss). Management determines the appropriate classification of its investments at the time of purchase and re-
evaluates such determination at each balance sheet date. 

Fair Value of Financial Instruments – Financial instruments including cash equivalents and accounts payable are carried in the financial statements 

at amounts that approximate their fair value based on the short maturities of those instruments. Marketable securities are carried at fair value and are more 
fully described in Note 6. The carrying amount of the Company’s credit facility with Hercules Capital, Inc. approximates fair value since the effective 
interest rate approximates market rates currently available to the Company.

Concentration of Credit Risk – Financial instruments that potentially subject the Company to significant concentrations of credit risk principally 

consist of cash, cash equivalents and marketable securities, if any. The Company places its cash and cash equivalents and marketable securities with 
financial institutions which management believes have high credit ratings. As part of its cash and investment management processes, the Company 
performs periodic evaluations of the credit standing of the financial institutions with whom it maintains deposits. 

Intellectual Property – The legal and professional costs incurred by the Company to acquire its patent rights are expensed as incurred and included 
in general and administrative expenses. At December 31, 2021 and 2020, the Company has determined that these expenses have not met the criteria to be 
capitalized since the future benefits to be derived from the patents is uncertain. Intellectual property related expenses for the years ended December 31, 
2021 and 2020 were $1.3 million and $1.0 million, respectively. 

Income Taxes – The Company follows the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 
740, Income Taxes (ASC 740), in reporting deferred income taxes. ASC 740 requires a company to recognize deferred tax liabilities and assets for expected 
future income tax consequences of events that have been recognized in the Company’s financial statements. Under this method, deferred tax assets and 
liabilities are determined based on temporary differences between financial statement carrying amounts and the 

114

 
tax basis of assets and liabilities using enacted tax rates in the years in which the temporary differences are expected to reverse. Valuation allowances are 
provided if based on the weight of available evidence, it is more likely than not that some or all the deferred tax assets will not be realized. 

The Company accounts for uncertain tax positions pursuant to ASC 740 which prescribes a recognition threshold and measurement process for 
financial statement recognition of uncertain tax positions taken or expected to be taken in a tax return. If the tax position meets this threshold, the benefit to 
be recognized is measured as the tax benefit having the highest likelihood of being realized upon ultimate settlement with the taxing authority. The 
Company recognizes interest accrued related to unrecognized tax benefits and penalties in the provision for income taxes. Management is not aware of any 
uncertain tax positions. 

Research and Development Costs – Research and development (R&D) costs are charged to expense as incurred and relate to salaries, employee 
benefits, stock-based compensation related to employees, consulting services, other operating costs and expenses associated with preclinical and clinical 
trial activities. Payments made by the Company in advance for research and development services not yet provided and/or for materials not yet received are 
recorded as prepaid expenses. Accrued liabilities are recorded related to those expenses for which vendors have not yet billed us with respect to services 
provided and/or materials that we have received. 

Preclinical and clinical trial expenses relate to third-party services, subject-related fees at the sites where the Company’s clinical trials are being 
conducted, laboratory costs, analysis costs, toxicology studies and investigator fees. Costs associated with these expenses are generally payable on the 
passage of time or when certain milestones are achieved. Expense is recorded during the period incurred or in the period in which a milestone is achieved. 
In order to ensure that the Company has adequately provided for preclinical and clinical expenses during the proper period, the Company maintains an 
accrual to cover these expenses. These accruals are assessed on a quarterly basis and are based on such assumptions as expected total cost, the number of 
subjects and clinical trial sites and length of the study. Actual results may differ from these estimates and could have a material impact on the Company’s 
reported results. The Company’s historical accrual estimates have not been materially different from actual costs. 

In-process research and development – Assets purchased in an asset acquisition transaction are expensed as in-process research and development 

(IPR&D) unless the assets acquired are deemed to have an alternative future use, provided that the acquired asset did not also include processes or activities 
that would constitute a “business” as defined under GAAP, the drug has not achieved regulatory approval for marketing and, absent obtaining such 
approval, has no established alternative future use. Acquired IPR&D payments are immediately expensed in the period in which they are incurred and 
include upfront payments, as well as transaction fees and subsequent pre-commercial milestone payments. Research and development costs incurred after 
the acquisition are expensed as incurred.

Stock-Based Compensation – Stock-based payments are accounted for in accordance with the provisions of ASC 718, Compensation – Stock 

Compensation. For options, the fair value of stock-based payments is estimated, on the date of grant, using the Black-Scholes option pricing model. For 
restricted stock, fair value is based on the fair value of the stock on the date of grant. The resulting fair value for restricted stock and options expected to 
vest is recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the applicable restricted stock or option. 
The Company records the effect of forfeitures and cancellations when they occur. 

Comprehensive Loss – Comprehensive loss is defined as the change in equity during a period from transactions and other events and/or 
circumstances from non-owner sources. For December 31, 2021, comprehensive loss is equal to the Company’s net loss of $57.8 million. For December 
31, 2020, comprehensive loss is equal to the Company's net loss of $37.6 million and a realized loss on marketable securities of $5.9 thousand. 

Net Loss Per Share – The Company computes net loss per share in accordance with the two-class method. Under the two-class method, net loss is 

allocated between common stock and other participating securities based on their participation rights. The Company has determined that the nonvested 
shares issued to the Helio founders represents a participating security and as such the nonvested shares are excluded from basic earnings per share. Net 
losses are not allocated to the nonvested stockholders for computing net loss per share under the two-class method 

115

 
because nonvested stockholders do not have contractual obligations to share in the losses of the Company. Basic earnings per share is calculated by 
dividing net loss allocable to common stockholders by the weighted average number of common stock outstanding.

Diluted net loss per share is computed using the more dilutive of (a) the two-class method, or (b) treasury stock method, as applicable, to the 

potentially dilutive instruments. The weighted-average number of common shares outstanding gives effect to all potentially dilutive common equivalent 
shares, including outstanding stock options and restricted stock, warrants, and nonvested shares.

Recent Accounting Pronouncements – In June 2016, the FASB issued (ASU) No. 2016-13, Financial Instruments—Credit Losses (Topic 326): 
Measurement of Credit Losses on Financial Instruments (ASU 2016-13). ASU 2016-13 requires that credit losses be reported as an allowance using an 
expected losses model, representing the entity’s current estimate of credit losses expected to be incurred. The accounting guidance currently in effect is 
based on an incurred loss model. For available-for-sale debt securities with unrealized losses, this standard now requires allowances to be recorded instead 
of reducing the amortized cost of the investment. The amendments under ASU 2016-13 are effective for interim and annual fiscal periods beginning after 
December 15, 2022. The Company is continuing to evaluate the impact of ASU 2016-13 but does not expect the adoption of this ASU to have a material 
impact on its consolidated financial statements. 

3.  HELIO VISION ACQUISITION

On January 28, 2019 (Closing Date), the Company acquired Helio Vision, Inc. (Helio). As a result of the acquisition, the Company initially issued 

an aggregate of 1,160,444 shares of common stock to the former securityholders and an advisor of Helio. The founders of Helio were issued 568,627 shares 
and non-founders were issued 591,817 shares. The Helio founders’ shares are subject to vesting based on continued service to the Company over three 
years from the Closing Date of which 98% are vested as of December 31, 2021. The Company recognizes the expense associated with the founders’ 
restricted shares as compensation expense on a straight-line basis as the shares vest over the three-year period. For the year ended December 31, 2021 and 
2020, the Company recorded $1.2 million and $1.3 million of research and development compensation expense, respectively, for the founders’ restricted 
shares.

In January 2021, pursuant to the terms of the acquisition agreement, the Company issued 246,562 shares of its common stock to the former 
securityholders of Helio (January Shares). In addition, the Company, subject to the conditions of the acquisition agreement, is contingently obligated to 
make additional payments to the former securityholders of Helio as follows:(a) $10.0 million of common stock following approval by the FDA of a new 
drug approval application for the prevention and/or treatment of proliferative vitreoretinopathy or a substantially similar label prior to the 10th anniversary 
of the Closing Date; and (b) $2.5 million of common stock following FDA approval of a new drug application for an indication (other than proliferative 
vitreoretinopathy) prior to the 12th anniversary of the Closing Date (the shares of common stock issuable pursuant to the preceding clauses (a) and (b) are 
referred to herein as the Milestone Shares), provided that in no event shall the Company be obligated to issue more than an aggregate of 5,248,885 shares 
of common stock. Additionally, in the event of certain change of control or divestitures by the Company, certain former convertible noteholders of Helio 
will be entitled to a tax gross-up payment in an amount not to exceed $1.0 million.  

116

 
 
The Company determined that liability accounting is not required for the Milestone Shares under FASB ASC Topic 480, Distinguishing Liabilities 

from Equity (ASC 480). The Company also determined that the Milestone Shares meet the scope exception as a derivative under FASB ASC Topic 815, 
Derivatives and Hedging (ASC 815), from inception of the Milestone Shares through December 31, 2021. Accordingly, the Milestone Shares are evaluated 
under FASB ASC Topic 450, Contingencies (ASC 450) and the Company will record a liability related to the Milestone Shares if the milestones are 
achieved, and the obligation to make additional payment(s) becomes probable. At that time, the Company will record the cost of the Milestone Shares 
issued to the founders as compensation expense and to the Helio non-founders as IPR&D expense if there is no alternative future use. At December 31, 
2020, the issuance of the January Shares was considered probable and $2.5 million was accrued as contingent consideration payable in stock and the 
Company recorded $1.8 million to IPR&D (Milestone IPR&D), which included a $0.5 million income tax benefit, and $1.2 million of compensation 
expense related to these January Shares, which amounted to 246,562 shares and were issued during the quarter ended March 31, 2021. No other milestones 
related to the remaining Milestone Shares are probable of being achieved as of December 31, 2021.

4.  NET LOSS PER SHARE 

For the years ended December 31, 2021 and 2020, diluted weighted-average common shares outstanding is equal to basic weighted-average 

common shares due to the Company’s net loss position. 

The following potentially dilutive securities outstanding have been excluded from the computation of diluted weighted-average shares outstanding, 

because such securities had an antidilutive impact: 

Options to purchase common stock
Nonvested restricted stock units
Nonvested founder shares 
Total of common stock equivalents

6.  FAIR VALUE MEASUREMENTS 

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most 

advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to 
measure fair value are performed in a manner to maximize the use of observable inputs and minimize the use of unobservable inputs. ASC 820, Fair Value 
Measurements, establishes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, 
that may be used to measure fair value, which are the following: 

Level 1 – Quoted prices in active markets that are accessible at the market date for identical unrestricted assets or liabilities. 

Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted 
prices in markets that are not active; or other inputs for which all significant inputs are observable or can be corroborated by observable market data 
for substantially the full term of the assets or liabilities. 

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. 

The following table presents information about the Company’s assets measured at fair value at December 31, 2021 and December 31, 2020:

The Company’s long-term debt obligation consists of amounts the Company is obligated to repay under its credit facility with Hercules Capital, Inc. 

(Hercules). In March 2019, the Company entered into a Loan and Security Agreement with Hercules and several banks and other financial institutions or 
entities, from time-to-time parties thereto (collectively, referred to as Lender), providing for a term loan of up to $60.0 million, subject to the satisfaction of 
certain conditions contained therein, that is secured by a lien covering all of the Company’s assets, other than the Company’s intellectual property (Loan 
and Security Agreement or the Hercules Credit Facility). The Loan and Security Agreement provided for (i) an initial term loan advance of up to $5.0 
million at the Company’s option, which expired unutilized on April 15, 2019; (ii) three additional term loan advances of up to $15.0 million each, at the 
Company’s option, available to the Company upon the occurrence of certain funding conditions prior to September 30, 2019 (2019 Tranche), March 31, 
2020 (2020 Tranche), and March 31, 2021 (2021 Tranche); and (iii) a final additional term loan advance (Fourth Loan Tranche) of up to $10.0 million prior 
to December 31, 2021, at the Company’s option, subject to approval by the Lender’s investment committee. The 2019 Tranche was drawn down in full by 
the Company in September 2019 and the 2020 Tranche and 2021 Tranche expired unutilized prior to the Company satisfying the funding conditions for 
such tranche. On April 20, 2021, the Company entered into the First Amendment (First Amendment) to the Loan and Security Agreement with Hercules. 
The First Amendment, among other things, (i) increased the Fourth Loan Tranche from $10.0 million to $20.0 million and extended the deadline for 
drawing down the Fourth Loan Tranche to July 1, 2022; (ii) lowered the variable per annum rate of interest on borrowings under the Loan and Security 
Agreement from the greater of (a) 9.10% and (b) the prime rate (as reported in the Wall Street Journal or any successor publication thereto) plus 3.10% to 
the greater of (x) the Prime Rate (as defined therein) plus 3.10% or (y) 8.60%; (iii) extended the expiration of the period in which interest-only payments on 
borrowings under the Loan and Security Agreement are required from May 1, 2021 to July 1, 2022; and (iv) following the satisfaction of certain conditions 
in April 2021, further extended the expiration of the interest-only period and the deadline for drawing down the Fourth Loan Tranche to May 1, 2023. 
Repayment of the aggregate outstanding principal balance of the term loan, in monthly installments, commences upon expiration of the interest-only period 
and continues through October 1, 2023 (Maturity Date). The First Amendment was determined to be a modification in accordance with FASB ASC Topic 
470, Debt and did not result in extinguishment.

 Associated with this debt facility, the Company incurred a commitment charge of $25,000, transaction costs of $273,186, a fee of $375,000 upon 

closing, and is required to pay a fee (End of Term Charge) of 6.95% multiplied by the aggregate amount of advances under the Loan and Security 
Agreement at maturity. The fees, transaction costs, and the End of Term Charge are amortized to interest expense from 2019 through the Maturity Date 
using the effective interest method. The effective interest rate was 10.8% at December 31, 2021. At the Company’s option, the Company may elect to 
prepay all, but not less than all, of the outstanding term loan by paying the entire principal balance and all accrued and unpaid interest thereon plus all fees 
and other amounts due under the Loan and Security Agreement, including a prepayment charge equal to 1.5% of the principal amount being prepaid. 

Following the effective time of the First Amendment and as of December 31, 2021, an aggregate of $35 million, subject to the terms and conditions 
of the Loan and Security Agreement, may be made available to the Company for borrowing, $15 million of which was funded prior to the date of the First 
Amendment.

The Loan and Security Agreement also contains certain events of default, representations, warranties and non-financial covenants of the Company. 
As of December 31, 2021, the Company was in material compliance with all covenants of the Hercules Credit Facility. In addition, subject to the terms of 
the Loan and Security Agreement, the Company granted the Lender the right to purchase up to an aggregate of $2.0 million of the Company’s equity 
securities, or instruments exercisable for or convertible into equity securities, sold to investors in financings upon the same terms and conditions afforded to 
such other investors.

10.  STOCKHOLDERS’ EQUITY

Common Stock

Each share of common stock is entitled to one vote. The holders of common stock are also entitled to receive dividends whenever funds are legally 
available and when declared by the board of directors, subject to the prior rights of holders of all classes of stock outstanding. As of December 31, 2021, a 
total of 4,622,870, 3,044,303, and 1,233,557, shares of common stock were reserved for issuance upon (i) the exercise of outstanding stock options, (ii) the 
issuance of stock awards under the Company’s Amended 2013 Plan, and (iii) the issuance of shares under the 2016 ESPP, respectively.

2018 Jefferies Sales Agreement

In December 2018, the Company entered into an Open Market Sales Agreement SM (2018 Jefferies Sales Agreement) with Jefferies LLC (Jefferies), 

as sales agent, pursuant to which the Company could offer and sell, from time to time through Jefferies, shares of common stock providing for aggregate 
sales proceeds of up to $50.0 million. During the year ended December 31, 2020, the Company sold, at a volume-weighted average price of $4.62, an 
aggregate of 9,351,749 shares of common stock and received $40.7 million after deducting commissions related to the 2018 Jefferies Sales Agreement and 
other offering costs. As of December 31, 2020, the Company had sold the maximum allowable amount and no further sales may be made under the 2018 
Jefferies Sales Agreement. 

2021 Jefferies Sales Agreement

In March 2021, the Company entered into an Open Market Sales Agreement SM (2021 Jefferies Sales Agreement) with Jefferies, as sales agent, 

pursuant to which the Company may offer and sell, from time to time through Jefferies, shares of common stock providing for aggregate sales proceeds of 
up to $100.0 million. The Company has no obligation to sell any shares under the 2021 Jefferies Sales Agreement, and could at any time

suspend solicitations and offers under the 2021 Jefferies Sales Agreement. No sales had been made pursuant to the 2021 Jefferies Sales Agreement as of 
December 31, 2021.

Underwritten Public Offerings

In January 2021, the Company sold 7.9 million shares of its common stock in an underwritten public offering at $9.50 per share, for an aggregate 

gross cash purchase price of $74.7 million or proceeds of $70.0 million after underwriters’ discount, commissions, and other offering expenses.

In May and June 2021, the Company sold an aggregate of 10.2 million shares of its common stock at a public offering price of $12.50 per share, in 

an underwritten public offering, for an aggregate gross cash purchase price of $127.8 million or proceeds of $119.8 million after underwriters’ discount, 
commissions, and other offering expenses, which included the partial exercise of the underwriters' option to purchase additional shares.

11.  INCOME TAXES 

No current or deferred tax provision expenses for federal and state income taxes have been recorded as the Company has incurred losses since 
inception for tax purposes. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities 
for financial reporting purposes and the amounts used for income tax purposes. 

In assessing the realizability of net deferred taxes in accordance with ASC 740 the Company considers whether it is more likely than not that some 
portion or all the deferred tax assets will not be realized. Based on the weight of available evidence, primarily the incurrence of net losses since inception, 
anticipated net losses in the near future, reversals of existing temporary differences and expiration of various federal and state attributes, the Company does 
not consider it more likely than not that some or all of the net deferred taxes will be realized. Accordingly, a 100% valuation allowance has been applied 
against net deferred taxes.  Effective January 1, 2021, the Company adopted ASU No. 2019-12, Income Taxes (Topic 740), which did not have a material 
impact to the Company’s financial statements. 

As of December 31, 2021, the Company had federal and state income tax net operating loss (NOL) carryforwards of approximately $226.0 million 

and $219.0 million, respectively. Federal NOL carryforwards generated through December 31, 2017 and state NOL carryforwards will expire at various 
dates through 2041. The federal NOL carryforwards generated during the year ended December 31, 2018 and thereafter will carryforward indefinitely. As 
of December 31, 2021, the Company had federal and state research and development tax credit carryforwards of approximately $6.9 million and $1.6 
million, respectively, which will expire at various dates through 2041. Additionally, as of December 31, 2021, the Company had a federal orphan drug tax 
credit carryforward of approximately $1.0 million that expires in 2041.

The Coronavirus Aid, Relief and Economic Security (CARES) Act was enacted in the United States on March 27, 2020. CARES includes several 

income tax provisions such as NOL carryback and carryforward benefits and other tax deduction benefits. As noted previously, the Company’s U.S. 
deferred tax asset has a full valuation allowance, accordingly these NOL and other benefit provisions have no impact on the Company’s financial 
statements for the period ended December 31, 2021.

Future changes in federal and state tax laws pertaining to net operating loss carryforwards may also cause limitations or restrictions from us 
claiming such net operating losses. If the net operating loss carryforwards become unavailable to us or are fully utilized, our future taxable income will not 
be shielded from federal and state income taxation absent certain U.S. federal and state tax credits, and the funds otherwise available for general corporate 
purposes would be reduced.

Under Section 382 of the Internal Revenue Code of 1986, as amended, a corporation that undergoes an “ownership change” is subject to limitations 

on its ability to utilize its pre-change NOLs and certain other tax assets to offset future taxable income. In general, an ownership change occurs if the 
aggregate stock ownership of certain stockholders increases by more than 50 percentage points over such stockholders’ lowest percentage ownership 
during the testing period (generally three years). Transactions involving the Company’s common stock within the testing period, even those outside the 
Company’s control such as purchases or sales by investors, could result in an ownership change. A limitation on the Company’s ability to utilize some or 
all its NOLs or credits could have a material adverse effect on the Company’s results of operations and cash flows.  Company believes, prior to December 
31, 2020 that the three ownership changes occurred since inception, and that a fourth ownership change was triggered during the year ended December 31, 
2021.  Management believes that its aggregate Section 382 limitation (including the additional limitation for recognized "built-in gains") is sufficient so 
that no current impairment of its pre-ownership change tax attributes is required.  Any future ownership changes, including those resulting from any recent 
or future financing activities, may cause our existing tax attributes to have additional limitations. 

As of December 31, 2021, the Company is subject to tax in the U.S. (Federal and Massachusetts). The Company is open to examination for the tax 

years ended December 31, 2021, 2020, 2019 and 2018. In addition, any loss years remain open to the extent that losses are available for carryover to future 
years. 

A reconciliation of the federal statutory tax rate of 21% to the Company’s effective income tax rates are as follows: 

Statutory tax rate
State taxes, net of federal benefits
Federal research and development credits
Change in valuation allowance
Stock-based compensation
Other

12.  STOCK INCENTIVE PLAN     

The Company approved the 2010 Employee, Director and Consultant Equity Incentive Plan (2010 Plan) in September 2010 to replace the 2004 

Employee, Director and Consultant Equity Incentive Plan. The 2010 Plan provided for the granting of stock options and restricted stock awards. The 2010 
Plan terminated upon the Company’s initial public offering in May 2014. However, grants made under the 2010 Plan are still governed by that plan. As of 
December 31, 2021, options to purchase 398,547 shares of common stock at a weighted average exercise price of $1.52 per share remained outstanding 
under the 2010 Plan. 

The Company approved the 2013 Equity Incentive Plan in October 2013. The 2013 Equity Incentive Plan became effective immediately on 

adoption. The 2013 Equity Incentive Plan was amended in June 2016 and June 2018, (Amended 2013 Plan). The Amended 2013 Plan provides for the 
granting of stock options, restricted stock, stock appreciation rights, stock units, and performance cash awards to certain employees, members of the board 
of directors and consultants of the Company. On January 1 of each year the aggregate number of common shares that may be issued under the Amended 
2013 Plan shall automatically increase by a number of shares equal to the lower of (a) 6% of the total number of shares of common stock outstanding on 
the last calendar day of the prior fiscal year, or (b) a number of shares of common stock determined by the Company’s board of directors. As of December 
31, 2021, options to purchase 4,224,323 shares of common stock at a weighted average exercise price of $7.23 per share and 501,255 shares of common 
stock underlying restricted stock units remained outstanding under the Amended 2013 Plan. As of December 31, 2021, there were 3,044,303 shares of 
common stock available for grant under the Amended 2013 Plan. As of January 1, 2022, the number of shares of common stock that may be issued under 
the Amended 2013 Plan was automatically increased by 3,485,526 shares, increasing the number of shares of common stock available for issuance under 
the Amended 2013 Plan to 6,529,829. 

In 2019 and 2020, the Company granted performance cash awards. The performance cash awards vest in four annual installments from the date of 

grant and entitle the employees to receive a cash payment, on the earlier of (i) four years from the date of grant or (ii) a change of control, equal in value to 
the amount by which the then value of the Company’s common stock exceeds the base value. As of December 31, 2021, $0.4 million was accrued as 
compensation expense for vested performance cash awards.

The Company recognizes stock-based compensation expense over the requisite service period. The Company’s share-based awards are accounted 

for as equity instruments. The amounts included in the consolidated statements of operations relating to stock-based compensation associated with the two 
equity incentive plans, performance cash awards, and Helio founders’ shares are as follows: 

Research and development expenses
General and administrative expenses
Total stock-based compensation expense

Terms of stock option agreements, including vesting requirements, are determined by the board of directors or its compensation committee, subject 
to the provisions of the respective plan from which they were granted. Options granted by the Company typically vest over a four-year period. The options 
are subject to acceleration of vesting in the event of certain change of control transactions. The options may be granted for a term of up to ten years from 
the date of grant. The exercise price for options granted under the Amended 2013 Plan must be at a price no less than 100% of the fair market value of a 
common share on the date of grant.

(a)

The aggregate intrinsic value in this table was calculated on the positive difference, if any, between the closing price per share of the Company’s 
common stock on December 31, 2021 of $4.00 and the per share exercise price of the underlying options. 

The Company records stock-based compensation related to stock options granted at fair value. During the years ended December 31, 2021 and 2020, 

the Company used the Black-Scholes option-pricing model to estimate the fair value of stock option grants and to determine the related compensation 
expense. The assumptions used in calculating the fair value of stock-based payment awards represent management’s best estimates. The weighted-average 
fair value of options granted was $7.95 and $2.57 for the years ended December 31, 2021 and 2020, respectively. The assumptions used in determining fair 
value of the employee stock options for the years ended December 31, 2021 and 2020, are as follows: 

Expected dividend yield
Anticipated volatility
Stock price
Exercise price
Expected life (years)
Risk free interest rate

$2.98 - $6.77
$2.98 - $6.77
5.50 - 6.25
0.39% - 1.71%  

The dividend yield of zero is based on the fact that the Company has never paid cash dividends and have no present intention to pay cash dividends. 
Expected volatility is estimated using the historical volatility of the Company. The Company has estimated the expected life of its employee stock options 
using the “simplified” method, whereby, the expected life equals the average of the vesting term and the original contractual term of the option for service-
based awards since the Company doesn’t have sufficient historical or implied data of its own. The risk-free interest rates for periods within the expected life 
of the option are based on the yields of zero-coupon United States Treasury securities. 

At December 31, 2021, there is approximately $7.5 million of unrecognized compensation cost relating to stock options outstanding, which the 

Company expects to recognize over a weighted average period of 2.50 years. Total unrecognized compensation cost will be adjusted for future forfeitures, 
if necessary. 

Restricted Stock Units 

Terms of restricted stock unit (RSUs) agreements, including vesting requirements, are determined by the board of directors or its compensation 

committee, subject to the provisions of the Amended 2013 Plan. RSUs granted by the Company typically vest over a four year period. In the event that the 
employees’ employment with the Company terminates any unvested shares are forfeited and revert to the Company. RSUs are not included in

The weighted-average fair value of RSUs granted was $11.71 and $3.78 per share for the years ended December 31, 2021 and 2020, respectively. As 

of December 31, 2021, the outstanding RSUs had unamortized stock-based compensation of $1.7 million with a weighted-average remaining recognition 
period of 1.91 years and an aggregate intrinsic value of $3.0 million. 

Employee Stock Purchase Plan 

In March 2016, the Company’s board of directors approved the 2016 Employee Stock Purchase Plan (2016 ESPP), which became effective in June 

2016 following the approval of the Company’s stockholders. The 2016 ESPP initially authorized the issuance of up to a total of 414,639 shares of the 
Company’s common stock to participating employees. The number of shares reserved for issuance under the 2016 ESPP automatically increases on the first 
business day of each fiscal year, commencing in 2017, by a number equal to the lower of (i) 1% of the shares of common stock outstanding on the last 
business day of the prior fiscal year; or (ii) the number of shares determined by the Company’s Board of Directors. Unless otherwise determined by the 
administrator of the 2016 ESPP, two offering periods of six months’ duration will begin each year on January 1 and July 1. Participating employees 
purchase stock under the 2016 ESPP at a price equal to the lower of 85% of the closing price on the applicable offering commencement date or 85% of the 
closing price on the applicable offering termination date. The fair value of the purchase rights granted under this plan was estimated on the date of grant 
using the Black-Scholes option-pricing model using assumptions as shown below:

Guarantees and Indemnifications 

As permitted under Delaware law, the Company indemnifies its officers and directors for certain events or occurrences while the officer or director is, 
or was, serving at the Company’s request in such capacity. The term of the indemnification is for the officer’s or director’s lifetime. Through December 31, 
2021, the Company had not experienced any losses related to these indemnification obligations and no material claims were outstanding. The Company 
does not expect significant claims related to these indemnification obligations, and consequently, concluded that the fair value of these obligations is 
negligible, and no related reserves were established. 

In-License Agreements

Madrigal Agreement

The Company is developing ADX-1612 pursuant to a License Agreement with Madrigal Pharmaceuticals, Inc. (Madrigal), entered into on 
December 26, 2016 (Madrigal Agreement). Pursuant to the Madrigal Agreement, the Company obtained an exclusive, worldwide license from Madrigal 
under certain patents and patent applications, and other licenses to intellectual property, to develop and commercialize Hsp90 inhibitors, including ADX-
1612, (collectively, Madrigal Agreement Products). The Company has agreed to use its commercially reasonable efforts to develop Madrigal Agreement 
Products.

In consideration for the rights licensed under the Madrigal Agreement, the Company paid Madrigal an upfront license fee of $250,000 and are 
obligated to make future regulatory and development and sales-dependent milestone payments to Madrigal of less than $340 million in the aggregate (over 
80% of such amount being tied to the Company’s achievement of increasingly greater annual worldwide net sales milestones), as well as royalty payments 
to Madrigal at a rate which, as a percentage of net sales, is in the high single digits for products containing ADX-1612 and mid-single digits for any other 
Hsp90 inhibitor product. The Company is also obligated under the Madrigal Agreement to pay Madrigal a percentage of certain sublicense revenue that the 
Company receives in connection with entering into any sublicensing arrangements with any third parties, at a percentage rate which tiers downward from 
the mid-twenties to low-single digits based on the development stage of the product at the time of the sublicense.

The Madrigal Agreement will remain in effect until all payment obligations under the Madrigal Agreement expire. The Company may terminate the 
Madrigal Agreement in its entirety or on a Madrigal Agreement Product-by Madrigal Agreement Product basis with timely notice to Madrigal. Either party 
may terminate the Madrigal Agreement for uncured material breach by the other party or upon certain insolvency or bankruptcy proceedings involving the 
other party, both with timely notice to the other party. In addition, Madrigal has the right to terminate the Madrigal Agreement if the Company, its affiliates, 
or sublicensees interfere with, challenge the validity or enforceability of, oppose the extension of, or grant of a supplementary protection certificate with 
respect to any of the Company’s licensed patents under the Madrigal Agreement. In the event of an early termination of the Madrigal Agreement, all rights 
licensed and developed by the Company under the Madrigal Agreement may revert back to Madrigal. Each party has agreed to indemnify the other party 
for certain third party claims arising under the Madrigal Agreement.

MEEI Agreement

The Company is developing ADX-2191 pursuant to an Exclusive License Agreement with Massachusetts Eye and Ear Infirmary (MEEI) originally 

entered into in July 2016 between MEEI and Helio Vision, Inc., as amended, (MEEI Agreement). The Company assumed the MEEI Agreement in 
connection with its 2019 acquisition of Helio Vision.

Pursuant and subject to the MEEI Agreement, the Company obtained an exclusive, worldwide license from MEEI to develop and commercialize 

ADX-2191 under certain patents and patent applications, and other licenses to intellectual property (MEEI Patent Rights). The Company has agreed to use 
commercially reasonable efforts, to develop ADX-2191 and to meet certain specified effort and achievement benchmarks by certain dates.

127

 
 
In consideration for the rights licensed under the MEEI Agreement, Helio Vision issued MEEI a number of shares of its preferred stock and Helio 

Vision agreed to pay non-creditable non-refundable license maintenance fees to MEEI of $15,000 on each of the second and third anniversary of the MEEI 
Agreement, $25,000 on each of the fourth and fifth anniversary of the MEEI Agreement and $35,000 on the sixth and each subsequent anniversary of the 
MEEI Agreement during the term of such agreement.  In addition, Helio Vision was obligated to make future sales-dependent milestone payments to MEEI 
of up to the low seven figures in the aggregate, as well as royalty payments to MEEI at a rate which, as a percentage of net sales, is in the low single digits 
for products that incorporate or use the MEEI Patent Rights in the United States and as a percentage in the low single digits for products that incorporate or 
use the MEEI Patent Rights outside the United States. The Company is also obligated under the MEEI Agreement to pay MEEI a percentage of certain 
sublicense revenue that it receives in connection with entering into any sublicensing arrangements with any third parties, at a percentage rate which tiers 
downward from low-double digits to mid-single digits based on the date of the sublicense.  Following the Company’s acquisition of Helio Vision, the 
Company became obligated to make any future payments owed under the MEEI Agreement. There is no additional equity consideration issuable under the 
MEEI Agreement.

The MEEI Agreement will remain in effect until the expiration date of the last to expire patent licensed under the MEEI Agreement. The Company 

may terminate the MEEI Agreement with timely written notice to MEEI. MEEI has the right to terminate the MEEI Agreement if it, subject to certain 
specified cure periods, ceases all business operations with respect to licensed products, fails to pay amounts due under the MEEI Agreement, fail to comply 
with certain due diligence obligations, defaults in our obligation to maintain insurance, one of our officers is convicted of a felony relating to the 
manufacture, use, sale or importation of licensed products, we materially breach any provisions of the MEEI Agreement or in the event of its insolvency or 
bankruptcy.

In the event of an early termination of the MEEI Agreement, all rights licensed and developed by the Company under the MEEI Agreement may 

revert back to MEEI. The Company has agreed to indemnify MEEI for certain claims that may arise under the MEEI Agreement.

14.  LEASES

The Company currently leases an office used to conduct business. The exercise of lease renewal options is at the Company’s discretion and the 
renewal to extend the lease terms are not included in the Company’s Right-Of-Use assets and lease liabilities as they are not reasonably certain of exercise. 
The Company regularly evaluates the renewal options and when they are reasonably certain of exercise, the Company includes the renewal period in its 
lease term. As the Company’s lease does not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available 
at the lease commencement date in determining the present value of the lease payments. In August 2021, the Company entered into a lease amendment 
extending the lease by 18 months through June 30, 2023.  which had an immaterial impact to the balance sheet as of December 31, 2021.  For the years 
ended December 31, 2021 and 2020, right of use assets obtained in exchange for lease obligations were $0.3 million and nil, respectively.

As of December 31, 2021, the Company maintained an unamortized Right-Of-Use asset with a corresponding operating lease liability of 

approximately $0.4 million based on the present value of the minimum rental payments in accordance with ASC Topic 842, Leases. The weighted average 
discount rate used for leases as of December 31, 2021 is 9.1%. The weighted average lease term as of December 31, 2021 is 1.5 years. The operating lease 
expense for the year ended December 31, 2021 was $0.2 million. Maturities and balance sheet presentation of our lease liabilities for all operating leases as 
of December 31, 2021 is as follows:

Exhibit 10.19 

Stephen G. Machatha, Ph.D. 

Dear Stephen, 

Aldeyra Therapeutics, Inc. (the “Company”) is pleased to offer you employment on the following terms:

1.

Position.    Your  initial  title  will  be  Vice  President  of  Chemistry,  Manufacturing  and  Controls  (CMC)  and  you 
will  initially  report  to  the  Company’s  Chief  Operating  Officer,  Scott  Young.    This  is  a  full-time  position.    While  you  render 
services to the Company, you will not engage in any other employment, consulting or other business activity (whether full-time 
or  part-time)  that  would  create  a  conflict  of  interest  with  the  Company.    By  signing  this  letter  agreement,  you  confirm  to  the 
Company  that  you  have  no  contractual  commitments  or  other  legal  obligations  that  would  prohibit  you  from  performing  your 
duties for the Company.

2.

Cash  Compensation.    The  Company  will  pay  you  a  starting  salary  at  the  rate  of  $8,958.33  per  pay  period 
(twenty  four  pay  periods  per  year),  payable  in  accordance  with  the  Company’s  standard  payroll  schedule.    This  salary  will  be 
subject to adjustment pursuant to the Company’s employee compensation policies in effect from time to time.  In addition, you 
will be eligible to be considered for an incentive bonus for each fiscal year of the Company.  The bonus (if any) will be awarded 
based on objective or subjective criteria established by the Company’s Chief Executive Officer and approved by the Company’s 
Board of Directors or its Compensation Committee.  Your target bonus will be equal to 25% of your annual base salary. (For the 
2015 fiscal year, you will be eligible for a bonus of up to $25,000.) Any bonus for a fiscal year is expected to be paid within 2.5 
months  after  the  close  of  that  fiscal  year,  but  only  if  you  are  still  employed  by  the  Company  at  the  time  of  payment.  The 
determinations of the Company’s Board of Directors or its Compensation Committee with respect to your bonus will be final and 
binding.

3.

Employee Benefits.  As a regular employee of the Company, you will be eligible to participate in a number of 
Company-sponsored  benefits.    In  addition,  you  will  be  entitled  to  3  weeks  paid  vacation  in  accordance  with  the  Company’s 
vacation policy, as in effect from time to time.  

4.

Stock Options.  Subject to the approval of the Company’s Board of Directors or its Compensation Committee, 

you will be granted an option to purchase 35,000 shares of the 

 
 
  
 
Stephen Machatha

Company’s  Common  Stock  (the  “Option”).    The  exercise  price  per  share  of  the  Option  will  be  determined  by  the  Board  of 
Directors or the Compensation Committee when the Option is granted.  The Option will be subject to the terms and conditions 
applicable  to  options  granted  under  the  Company’s  2013  Stock  Plan  (the  “Plan”),  as  described  in  the  Plan  and  the  applicable 
Stock Option Agreement.  You will vest in 25% of the Option shares after 12 months of continuous service, and the balance will 
vest in equal monthly installments over the next 36 months of continuous service, as described in the applicable Stock Option 
Agreement.

5.

Severance Benefits.

(a)

General.  If  you  are  subject  to  an  Involuntary  Termination,  then  you  will  be  entitled  to  the 
benefits described in this Section 5.  However, this Section 5 will not apply unless you (i) have returned all Company property in 
you r possession, (ii) have resigned as a member of the Boards of Directors of the Company and all of its subsidiaries, to the 
extent  applicable,  and  (iii)  have  executed  a  general  release  of  all  claims  that  you  may  have  against  the  Company  or  persons 
affiliated with the Company. The release must be in the form prescribed by the Company, without alterations. You must execute 
and  return  the  release  on  or  before  the  date  specified  by  the  Company  in  the  prescribed  form  (the  "Release  Deadline").  The 
Release Deadline will in no event be later than 50 days after your Separation. If you fail to return the release on or before the 
Release Deadline, or if you revoke the release, then you will not be entitled to the benefits described in this Section 5.

(b)

Salary Continuation. If you are subject to an Involuntary Termination, then the Company will 
continue to pay your base salary for a period of 6 months after your Separation. Your base salary will be paid at the rate in effect 
at  the  time  of  your  Separation  and  in  accordance  with  the  Company's  standard  payroll  procedures.  The  salary  continuation 
payments  will  commence  within  60  days  after  your  Separation  and,  once  they  commence,  will  include  any  unpaid  amounts 
accrued from the date of your Separation. However, if the 60-day period described in the preceding sentence spans two calendar 
years, then the payments will in any event begin in the second calendar year.

(c)

Cash Bonus. If you are subject to an Involuntary Termination, then the Company will pay you 
a lump-sum in cash equal to the greater of (i) your target bonus for the year in which the Involuntary Termination occurs or (ii) 
the  actual  bonus  paid  to  you  with  respect  to  the  Company's  most  recently  completed  fiscal  year.  Such  payment  will  be  made 
within  60  days  after  your  Separation;  however,  if  such  60-day  period  spans  two  calendar  years,  then  the  payment  will  in  any 
event be made in the second calendar year. 

(d)

COBRA.      If  you  are  subject  to  an  Involuntary  Termination  and  you  elect  to  continue  your 
health insurance coverage under the Consolidated Omnibus Budget Reconciliation Act ("COBRA") following your Separation, 
then  the Company will pay the same portion of your monthly  premium under COBRA as it pays for active employees and their 
eligible dependents until  the earliest of (i) the close of the 6-month period following your Separation,  (ii) the expiration  of your 
continuation coverage under COBRA or (iii) the date when you become  

 
 
 
Stephen Machatha

payments will be treated as taxable compensation income to you if required or advisable, in the Company's sole discretion, to 
avoid adverse consequences to you, the Company or the Company's other employees.

6.

Confidentiality, Non-Competition and Work Product Agreement.  Like all Company employees, you will be 
required,  as  a  condition  of  your  employment  with  the  Company,  to  sign  the  Company’s  standard  “Confidentiality,  Non-
Competition and Work Product Agreement”, a copy of which is attached hereto as Exhibit A.

7.

Employment  Relationship.    Employment  with  the  Company  is  for  no  specific  period  of  time.    Your 
employment with the Company will be “at will,” meaning that either you or the Company may terminate your employment at any 
time and for any reason, with or without cause.  Any contrary representations that may have been made to you are superseded by 
this letter agreement.  This is the full and complete agreement between you and the Company on this term.  Although your job 
duties, title, compensation and benefits, as well as the Company’s personnel policies and procedures, may change from time to 
time, the “at will” nature of your employment may only be changed in an express written agreement signed by you and a duly 
authorized officer of the Company (other than you).

from  the  Company.    You  agree  that  the  Company  does  not  have  a  duty  to  design  its  compensation  policies  in  a  manner  that 
minimizes your tax liabilities, and you will not make any claim against the Company, its Board of Directors or its Compensation 
Committee related to tax liabilities arising from your compensation.

9.

Interpretation,  Amendment  and  Enforcement.    This  letter  agreement  and  Exhibit  A  supersede  and  replace 
any    prior  agreements,  representations  or  understandings  (whether  written,  oral,  implied  or  otherwise)  between  you  and  the 
Company  and  constitute  the  complete  agreement  between  you  and  the  Company  regarding  the  subject  matter  set  forth  herein.  
This letter agreement may not be amended or modified, except by an express written agreement signed by both you and a duly 
authorized  officer  of  the  Company.    The  terms  of  this  letter  agreement  and  the  resolution  of  any  disputes  as  to  the  meaning,

agreement, your employment with the Company or any other relationship between you and the Company (the “Disputes”) will be
