LETTING SCIENCE LEAD THE WAY

April 30, 2021

Dear Fellow Shareholders:

One year ago, few — perhaps none — could have predicted all the ways that COVID-19
would affect our lives, our families, our communities and our world. The global pandemic
has changed how we work, communicate and socialize. Despite largely working remotely,
all of us at Omeros have remained unified in our commitment to and passion for
delivering first-of-kind therapeutics to patients who need them, most recently highlighted
by our Biologics License Application (BLA) for narsoplimab to treat hematopoietic stem
cell transplant-associated thrombotic microangiopathy (HSCT-TMA). At Omeros, ‘‘letting
science lead the way’’ is not just a tagline, it’s how we function. It’s what led us to
realize that narsoplimab might just be a premier treatment for critically ill COVID-19
patients. That realization is increasingly shared by leading scientists and organizations
worldwide. Having successfully treated critically ill patients under compassionate use both
in the US and abroad, we now are participating in a COVID-19 controlled clinical trial
platform. The science, and the data available to date, tell us that narsoplimab and
Omeros may well play an important role in limiting the devastation wrought by this
pandemic.

2020 Highlights

Narsoplimab is our fully human antibody against MASP-2, the effector enzyme of the lectin
pathway of complement. In November 2020, we submitted our narsoplimab BLA for the
treatment of HSCT-TMA, which FDA accepted for priority review, setting an action date
under the Prescription Drug User Fee Act (PDUFA) of July 17, 2021. We continue to treat
patients under compassionate use, including a 7-year-old girl in India who, following
stem-cell transplantation, developed severe gastrointestinal TMA requiring transfusions.
Her physician requested narsoplimab and initiated treatment. Her TMA resolved, and her
physician credits narsoplimab with saving her life.

As numerous leading research groups internationally have confirmed, COVID-19, like
HSCT-TMA, is an endothelial injury syndrome. At the outbreak of the pandemic, we and
our colleagues in Italy identified the pathophysiologic similarities between HSCT-TMA and
COVID-19, and narsoplimab was used under compassionate use in Bergamo, the
pandemic’s epicenter for the western world. The first cohort of patients, all of whom
initially required mechanical ventilation prior to narsoplimab treatment, recovered and
showed reduction in all assessed laboratory markers of endothelial damage and
inflammation. Results from these patients, including a retrospective comparison against
two control groups, were published in Immunobiology. Five to six months following
treatment, none of these patients showed any clinical or laboratory evidence of
‘‘long-haul’’ effects of COVID-19. With the second surge of COVID-19, we continued
treating critically ill patients in both Italy and the US with similar outcomes. Against a

NEXT-GENERATION  THERAPEUTICS  TRANSFORMING  PATIENT  CARE  TODAY(cid:31)

backdrop of problems with vaccine roll-out and durability of effect, productive discussions
are advancing with governmental agencies and non-governmental organizations.
Narsoplimab is currently being evaluated in the treatment of critically ill COVID-19
patients as part of the I-SPY COVID-19 platform trial sponsored by the Quantum Leap
Healthcare Collaborative. Narsoplimab is the only complement inhibitor invited to
participate in the I-SPY trial.

In addition to our work in HSCT-TMA and COVID-19, Omeros’ Phase 3 programs evaluating
narsoplimab in immunoglobulin-A (IgA) nephropathy, which now has over 120 sites
activated worldwide, and in atypical hemolytic uremic syndrome continue to progress. As
part of lifecycle planning for narsoplimab, we are also advancing development of a small-
molecule MASP-2 inhibitor designed for oral administration and OMS1029, our long-acting
MASP-2 antibody targeting once-monthly or less frequent subcutaneous dosing.

In September, we further expanded the clinical-stage assets in our complement franchise
with the initiation of a Phase 1 clinical trial evaluating the safety, tolerability and
pharmacokinetics of OMS906, our MASP-3 inhibitor targeting the alternative pathway of
complement. We, along with others in industry and the complement research community,
believe that MASP-3 is the key activator and premier drug target in the alternative
pathway.

Our FDA-approved ophthalmic product OMIDRIA� (phenylephrine and ketorolac intraocular
solution) 1%/0.3% continued to grow its utilization as patient access to OMIDRIA continued
to expand. We successfully added to our list of customers a good number of large chains
of ambulatory surgery centers (ASCs) and collections of surgical facilities owned by
private equity groups. On October 1, OMIDRIA reached the end of its extension term of
pass-through reimbursement. Two months later, the Centers for Medicare and Medicaid
Services (CMS) restored separate payment for OMIDRIA in ASCs under CMS’ packaged-
payment exclusion for non-opioid pain-management surgical drugs. In parallel, the
Non-Opioids Prevent Addiction In the Nation Act, or the NOPAIN Act, which would
statutorily extend separate payment for non-opioid alternatives like OMIDRIA in both ASCs
and hospital outpatient departments, increasingly gains broad bipartisan and bicameral
support.

Our G protein-coupled receptor (GPCR) program, particularly GPR174, continues to be an
exciting area and a priority for Omeros. Omeros discovered the role of GPR174 as a new
cancer immunotherapy target. In mouse tumor models, GPR174 deficiency enhances T-cell
proliferation and tumor-killing phenotypes, resulting in reduced tumor growth. We believe
that GPR174 can be combined with existing cancer immunotherapies to improve their
response rates. Our team is working to develop both small-molecule and antibody
inhibitors of GPR174.

2020 will be remembered for the outbreak of the COVID-19 pandemic, indelibly reminding
us all of the importance of health, the value of family and friends, and the strength of
working together. I am immensely proud of how Omeros has joined in the global fight
against COVID-19 and of our dedicated team’s achievements throughout the year and

NEXT-GENERATION  THERAPEUTICS  TRANSFORMING  PATIENT  CARE  TODAY�

across our programs — achievements that would not have been possible without our
research collaborators, investigators and clinical trial participants and their families. I
expect that Omeros, this year and beyond, will continue to deliver successes that benefit
patients.

On behalf of our board of directors and employees, I would like to wish all of you and
your families good health, and we thank you for your support.

Sincerely,

29APR202007131615

This Annual Report on Form 10-K contains forward-looking statements reflecting our current expectations that 

involve risks and uncertainties. Actual results may differ materially from those discussed in these forward-looking 
statements due to a number of factors, including those set forth in the section entitled “Risk Factors” and elsewhere in 
this Annual Report. Please refer to the special note regarding forward-looking statements at the beginning of this 
Annual Report on Form 10-K for further information. 

ITEM  1.             BUSINESS 

Overview 

We are a commercial-stage biopharmaceutical company committed to discovering, developing and commercializing 

small-molecule and protein therapeutics for large-market as well as orphan indications targeting inflammation, 
complement-mediated diseases, disorders of the central nervous system and immune-related diseases, including cancers. 

Our drug product OMIDRIA® is marketed in the United States for use during cataract surgery or intraocular lens 

replacement for adult and pediatric patients. Our drug candidate narsoplimab is the subject of a biologics license 
application (“BLA”) under priority review by the U.S. Food and Drug Administration (“FDA”) for the treatment of 
hematopoietic stem cell transplant-associated thrombotic microangiopathy (“HSCT-TMA”). We also have multiple 
Phase 3 and Phase 2 clinical-stage development programs in our pipeline, which are focused on: complement-mediated 
disorders, including immunoglobulin A (“IgA”) nephropathy, atypical hemolytic uremic syndrome (“aHUS”) and 
COVID-19. We have also initiated a Phase 1 clinical program for our MASP-3 inhibitor OMS906 targeting the 
alternative pathway of complement and have successfully completed a Phase 1 study in our phosphodiesterase 7 
(“PDE7”) program focused on addiction. In addition, we have a diverse group of preclinical programs, including 
GPR174, a novel target in immuno-oncology that modulates a new cancer immunity axis that we discovered. Small-
molecule and antibody inhibitors of GPR174 are part of our proprietary G protein-coupled receptor (“GPCR”) platform 
through which we control 54 GPCR drug targets and their corresponding compounds. We also possess a proprietary-
asset-enabled antibody-generating technology. We have retained control of all commercial rights for OMIDRIA and 
each of our product candidates and programs. 

Commercial Product -- OMIDRIA® (phenylephrine and ketorolac intraocular solution) 1%/0.3% 

Overview. OMIDRIA is approved by FDA for use during cataract surgery or intraocular lens (“IOL”) replacement 
to maintain pupil size by preventing intraoperative miosis (pupil constriction) and to reduce postoperative ocular pain. 
Outside the U.S., we have received approval from the European Commission (“EC”) to market OMIDRIA in the 
European Economic Area (“EEA”), for use during cataract surgery and other IOL replacement procedures for 
maintenance of intraoperative mydriasis (pupil dilation), prevention of intraoperative miosis and reduction of acute 
postoperative ocular pain. 

OMIDRIA is a proprietary drug product containing two active pharmaceutical ingredients (“APIs”): ketorolac, an 
anti-inflammatory agent, and phenylephrine, a mydriatic, or pupil dilating, agent. Cataract and other lens replacement 
surgery involves replacement of the original lens of the eye with an artificial intraocular lens. OMIDRIA is added to 
standard irrigation solution used during cataract and lens replacement surgery and is delivered intracamerally, or within 
the anterior chamber of the eye, to the site of the surgical trauma throughout the procedure. Preventing pupil constriction 
is essential for these procedures and, if miosis occurs, the risk of damaging structures within the eye and other 
complications increases, as does the operating time required to perform the procedure. 

United States. We launched OMIDRIA in the U.S. in the second quarter of 2015 and sell OMIDRIA primarily 
through wholesalers which, in turn, sell to ASCs and hospitals. CMS, the federal agency responsible for administering 
the Medicare program, granted transitional pass-through reimbursement status for OMIDRIA in 2014, effective from 
January 1, 2015 through December 31, 2017 and, in March 2018, Congress extended pass-through reimbursement status 
for a small number of drugs, including OMIDRIA, for an additional two years, running from October 1, 2018 through 
September 30, 2020. Pass-through status allows for separate payment (i.e., outside the packaged payment rate for the 

1 

 
surgical procedure) under Medicare Part B. In CMS’ CY2021 Hospital Outpatient Prospective Payment System 
(HOPPS) and Ambulatory Surgical Center (ASC) Payment System Final Rule, CMS confirmed that OMIDRIA, as an 
otherwise policy packaged drug following OMIDRIA’s expiration of pass-through status on October 1, 2020, qualifies 
for separate payment when used on Medicare Part B patients in the ASC setting under CMS’ policy for non-opioid pain 
management surgical drugs. CMS made separate payment for OMIDRIA effective retroactively as of October 1, 2020. 
CMS’ current non-opioid separate payment policy and, as a result, separate payment for OMIDRIA thereunder, like 
other CMS policies in the OPPS and ASC systems, can be changed by CMS through its OPPS/ASC annual rulemaking 
and comment process. We believe that CMS will continue its separate payment policy for non-opioid pain management 
surgical drugs, which has been in effect since 2019, and that OMIDRIA will continue to be separately reimbursed when 
used in the ASC setting. 

We have implemented a variety of programs and arrangements to facilitate the availability of OMIDRIA to cataract 

and IOL replacement patients in the U.S., including the following: 

• 

• 

• 

various purchase volume-discount programs for OMIDRIA; 

agreements to enable discounts on qualifying purchases of OMIDRIA by certain U.S. government purchasers 
and other eligible entities, such as 340B-eligible hospitals and clinics; and 

the OMIDRIAssure® Reimbursement Services Program, which we refer to as OMIDRIAssure. 

OMIDRIAssure provides coverage and reimbursement support services for surgeons and facilities to help remove 

uncertainties about coding, billing and coverage of OMIDRIA and to enable better access to the drug for patients facing 
financial barriers. Under our “Equal Access” patient assistance program, financially eligible uninsured and government-
insured patients receive OMIDRIA free of charge for use during surgery. Through our “We Pay the Difference” program 
we pay the facility, on behalf of commercially insured patients, the difference between the facility’s acquisition cost for 
OMIDRIA, after accounting for any applicable volume discounts, and the amount covered by the patient’s insurance. 

European Union and other International Territories. In July 2018, we placed OMIDRIA on the market in the 
European Union (“EU”) on a limited basis and continue to maintain the ongoing validity of the Marketing Authorization 
for OMIDRIA in EU member states and EEA countries. Decisions about price and reimbursement for OMIDRIA are 
made on a country-by-country basis and may be required before marketing may occur in a particular country. At this 
time we do not expect to see significant sales of OMIDRIA in any countries within the EEA or other international 
territories if we are unable to complete a broad sales launch in any such country either independently or through 
partnerships for the marketing and distribution of OMIDRIA.

MASP Inhibitor Clinical Programs 

MASP-2 Program - Narsoplimab (OMS721) - Lectin Pathway Disorders 

Overview. Mannan-binding lectin-associated serine protease-2 (“MASP-2”), is a novel pro-inflammatory protein 
target involved in activation of the complement system, which is an important component of the immune system. The 
complement system plays a role in the body’s inflammatory response and becomes activated as a result of tissue damage 
or trauma or microbial pathogen invasion. Inappropriate or uncontrolled activation of the complement system can cause 
diseases characterized by serious tissue injury. Three main pathways can activate the complement system: classical, 
alternative and lectin. MASP-2 is recognized as the effector enzyme of the lectin pathway and is required for the 
function of this pathway. Importantly, inhibition of MASP-2 has been demonstrated not to interfere with the antibody-
dependent classical complement activation pathway, a critical component of the acquired immune response to infection 
the abnormal function of which is associated with a wide range of autoimmune disorders. 

Our proprietary, patented lead human monoclonal antibody targeting MASP-2, which we have referred to as 
OMS721, has been assigned the nonproprietary name narsoplimab. The current development focus for narsoplimab is 
diseases in which the lectin pathway has been shown to contribute to significant tissue injury and pathology. When not 
treated, these diseases are typically characterized by significant end organ injuries, such as kidney or central nervous 
system injury. We have completed our pivotal clinical trial for narsoplimab in HSCT-TMA, and Phase 3 clinical 
programs are in process for narsoplimab in IgA nephropathy and aHUS. Narsoplimab is also being evaluated for 
treatment of COVID-19 in an adaptive platform trial and has been used under compassionate use to treat COVID-19 
patients in Italy and in the U.S.

Thrombotic Microangiopathies 

HSCT-TMA. In November 2020, we completed the rolling submission to FDA of our BLA for narsoplimab for the 
treatment of HSCT-TMA, a frequently lethal complication of HSCT. The BLA has been accepted for filing by FDA and 
granted priority review with an FDA action date under the Prescription Drug User Fee Act (“PDUFA”) of July 17, 2021.  

In October 2020, we reported final clinical data from our pivotal trial of narsoplimab in HSCT-TMA. The single-

arm, open-label trial included safety and efficacy endpoints that were previously agreed to with FDA. These endpoints 
were assessed for (1) all 28 patients who received at least one dose of narsoplimab and (2) patients who received the 
protocol-specified dosing of at least four weeks of narsoplimab.  

The primary efficacy endpoint in the trial was the proportion of patients who achieved designated “responder” status 

based on improvement in HSCT-TMA laboratory markers and clinical status. This is referred to as the “complete 
response rate.” The primary laboratory markers that were evaluated were platelet count and lactate dehydrogenase 
(“LDH”), levels, while improvement in clinical status was evaluated based on organ function and transfusions. Each 
patient was required to show improvement in both laboratory markers and clinical status to be considered a responder. 
All others were considered non-responders. 

Among patients who received at least one dose of narsoplimab, the complete response rate was 61% (95% 
confidence interval [CI] 40.6 to 78.5; p<0.0001), while the complete response rate among patients who received the 
protocol-specified narsoplimab treatment of at least four weeks of dosing was 74% (95% CI 51.6 to 89.8; p<0.0001). 
The response rates and their respective lower levels of the 95% confidence intervals are a multiple of the pre-specified 
efficacy threshold of 15%. 

Secondary endpoints in the trial were survival rates and change from baseline in HSCT-TMA laboratory markers. 
Among all treated patients, 68% survived for at least 100 days following HSCT-TMA diagnosis, while 83% of patients 
who received treatment for at least four weeks and 94% of the responders achieved this endpoint. Median overall 
survival was 274 days among all patients and 361 days among patients who received the protocol-specified treatment of 
at least four weeks. Median survival could not be estimated for responders because more than half of the responders 
were alive at last follow-up. Results also included statistically significant improvements in platelet count, LDH and 
haptoglobin. The treated population had multiple high-risk features that portend a poor outcome, including the 
persistence of HSCT-TMA despite modification of immunosuppression (which was a criterion for entry into the trial), 
graft-versus-host disease, significant infections, non-infectious pulmonary complications and neurological findings. The 
most common adverse events observed in the trial were nausea, vomiting, diarrhea, hypokalemia, neutropenia and fever, 
which are all common in stem-cell transplant patients. Six deaths occurred during the trial. These were due to sepsis, 
progression of the underlying disease, and graft-versus-host disease with TMA. All of these are common causes of death 
in this patient population. 

In Europe, the EMA has confirmed narsoplimab’s eligibility for EMA’s centralized review of a single MAA that, if 

approved, authorizes the product to be marketed in all EU member states and EEA countries. We are targeting to 
complete our MAA submission in 2021. 

In the U.S., FDA has granted narsoplimab (1) breakthrough therapy designation in patients who have persistent 
TMA despite modification of immunosuppressive therapy, (2) priority review for the HSCT-TMA BLA, (3) orphan drug 
designation for the prevention (inhibition) of complement-mediated TMAs, and (4) orphan drug designation for the 
treatment of HSCT-TMA. The EC also granted narsoplimab designation as an orphan medicinal product for treatment in 
hematopoietic stem cell transplantation. 

aHUS. We have an ongoing Phase 3 clinical program in patients with aHUS with active sites in the U.S., Europe 

and Asia. The single-arm, open-label Phase 3 clinical trial in patients with newly diagnosed or ongoing aHUS is 
enrolling. This trial is targeting approximately 40 patients for EU approval and U.S. accelerated approval with 80 
patients required for full approval in the U.S. The trial includes multiple sites in the U.S., Asia and Europe, and is 
actively enrolling, though enrollment has been slowed in part due to prioritizing the use of resources within our 
narsoplimab programs on HSCT-TMA, IgA nephropathy, and COVID-19. Dosing consists of an initial IV loading 

5 

followed by daily subcutaneous dosing. Based on discussions with FDA and the EMA, we expect that the clinical 
package for the BLA would be similar to that which formed the basis of approval for Soliris® (eculizumab), which is 
marketed by Alexion Pharmaceuticals, Inc. 

The FDA has granted to narsoplimab orphan drug designation for the prevention (inhibition) of complement-

mediated TMAs and fast-track designation for the treatment of patients with aHUS. 

Renal Disease 

Phase 3 Program - IgA Nephropathy. Patient enrollment is ongoing in our Phase 3 clinical trial evaluating 
narsoplimab in IgA nephropathy, which is referred to as ARTEMIS-IGAN. The single Phase 3 trial design is a 
randomized, double-blind, placebo-controlled multicenter trial in patients at least 18 years of age with biopsy-confirmed 
IgA nephropathy and with 24-hour urine protein excretion greater than 1 g/day at baseline on optimized renin-
angiotensin system blockade. This trial includes a run-in period. Initially, patients are expected to receive an IV dose of 
study drug each week for 12 weeks; additional weekly dosing can be administered to achieve optimal response. The 
primary endpoint, which could suffice for full or accelerated approval depending on the effect size, is reduction in 
proteinuria at 36 weeks after the start of dosing. The trial is designed to allow intra-trial adjustment in sample size. For 
the purposes of safety and efficacy assessments, the initial sample size for the proteinuria endpoint is estimated at 140 
patients in each of the treatment and placebo groups. This will include a subset of patients with high levels of proteinuria 
(i.e., equal to or greater than 2 g/day) at baseline, and a substantial improvement at 36 weeks in this subset of patients 
alone could potentially form the basis for approval. We believe that the trial design will allow assessment for either full 
or accelerated approval at 36 weeks based on proteinuria results either (1) across the general population of study patients 
or (2) in the high-proteinuria subset of patients. In the event of full approval, estimated glomerular filtration rate 
(“eGFR”) becomes a safety endpoint only. In the event that the primary endpoint at 36 weeks results in accelerated 
approval from FDA, change in eGFR is expected to be assessed at approximately two years after the start of dosing. 
These eGFR data, if satisfactory, would then likely form the basis for full approval. In response to investigators’ 
concerns about extended withholding of narsoplimab treatment from any high-proteinuria patient initially randomized to 
the placebo-treated group, FDA will allow patients in that sub-population open-label treatment with narsoplimab after at 
least 1 year of blinded treatment. 

In the U.S., narsoplimab has received breakthrough therapy and orphan drug designations from FDA for the 
treatment of IgA nephropathy. In Europe, narsoplimab has received orphan drug designation from the EMA in patients 
with IgA nephropathy. 

Phase 2 Clinical Trial - Renal Diseases. We have been conducting a Phase 2 clinical trial in patients with 
complement-associated renal diseases, specifically designed to cover: (1) IgA nephropathy; (2) membranous 
nephropathy; and (3) lupus nephritis. An initial open-label cohort of patients completed treatment in May 2017. In 
August 2020, a manuscript detailing the results of the Phase 2 clinical trial in patients with IgA nephropathy was 
published in the peer-reviewed journal Kidney International Reports.  

COVID-19.  In March 2020, in response to a request from physicians at the Papa Giovanni XXIII Hospital in 
Bergamo, Italy, we initiated a compassionate use program for narsoplimab to treat patients with severe COVID-19 
requiring mechanical ventilation.  

The initial cohort treated under this compassionate use program included a total of six COVID-19 patients treated 

with narsoplimab under compassionate use, all with acute respiratory distress syndrome (“ARDS”) and requiring 
continuous positive airway pressure (“CPAP”) or intubation. At baseline, circulating endothelial cell (“CEC”) counts 
and serum levels of interleukin-6 (“IL-6”), interleukin-8 (“IL-8”), C-reactive protein (“CRP”), LDH, D-dimer and 
aspartate aminotransferase (“AST”) were markedly elevated. During the course of the compassionate use program, 
institutional guidelines at the treating hospital were updated to require that all COVID-19 patients in the hospital receive 
steroids. One patient treated with narsoplimab did not receive steroids. Of the five narsoplimab-treated patients who 
received steroids, two initiated them after already improving such that CPAP was no longer required or was discontinued 
the following day. The study evaluated CEC counts in a separate group of four patients receiving only steroids for a 
short duration, and the counts were found to be unaffected by steroid administration. This suggests that any beneficial 

6 

effect of steroids on COVID-19-associated endothelial damage may be delayed and had little effect on the recovery 
course of the narsoplimab-treated patients who initiated steroid treatment after improving. 

Narsoplimab treatment was associated with rapid and sustained reduction across all of these markers of endothelial 

damage and inflammation. In addition, massive bilateral pulmonary thromboses, seen in two of the patients, resolved 
while on narsoplimab. All six narsoplimab-treated patients recovered, survived and were discharged. Narsoplimab was 
well tolerated and no adverse drug reactions were reported. Two control groups with similar baseline characteristics 
were used for retrospective comparison, both showing substantial mortality rates of 32% and 53%. A manuscript 
detailing the results of the initial cohort of Bergamo patients treated with narsoplimab was published in the peer-
reviewed journal Immunobiology. 

All six patients were evaluated five to six months after cessation of narsoplimab treatment. None of them showed 

any clinical or laboratory evidence of long-term effects of COVID-19, such as cognitive impairment or cardiac, 
pulmonary or other organ disorder, commonly seen following resolution of initial COVID-19 symptoms. 

Endothelial damage and resultant thromboses are significant to the pathophysiology of COVID-19, and we believe 
these data illustrate the importance of inhibiting the lectin pathway to treat critically ill COVID-19 patients. Endothelial 
damage activates the lectin pathway of complement. We believe the results observed following narsoplimab treatment in 
critically ill COVID-19 patients at Papa Giovanni were consistent with those seen in HSCT-TMA and underscore the 
pathophysiologic similarities between these two disorders. Narsoplimab has been shown to inhibit lectin pathway 
activation and to block the MASP-2-mediated conversion of prothrombin to thrombin, microvascular injury-associated 
thrombus formation and the activation of factor XII as well as the MASP-2-mediated activation of kallikrein. We believe 
that the anticoagulant effects of narsoplimab may provide therapeutic benefits in both HSCT-TMA and COVID-19. 

Following treatment of the initial six patients under the compassionate use program in Italy, we have continued 
compassionate-use treatment with nine more patients in Italy and four patients in the U.S. All of these patients prior to 
receiving narsoplimab were severely ill, intubated, had multiple comorbidities, and had failed other therapies, including 
anti-virals, targeted anti-inflammatory therapeutics, convalescent plasma and steroids. Following treatment with 
narsoplimab, the laboratory improvements and clinical outcomes of these patients are similar to those seen in the initial 
cohort of Bergamo patients.  

Narsoplimab is also the only complement inhibitor included in the I-SPY COVID-19 platform trial sponsored by 
Quantum Leap Healthcare Collaborative, which is evaluating drugs and investigational products for the treatment of 
critically ill COVID-19 patients. The trial utilizes Quantum Leap Healthcare Collaborative's adaptive platform trial 
design, which is intended to increase trial efficiency by minimizing the number of participants and time required to 
evaluate potential treatments.   

Discussions regarding the use of narsoplimab in COVID-19  with leaders across various U.S. government agencies 

as well as international regulatory authorities and global healthcare organizations continue to progress.

MASP-3 Program - OMS906 - Alternative Pathway Disorders 

Overview. As part of our MASP program, we have identified mannan-binding lectin-associated serine protease 3 
(“MASP-3”), which has been shown to be the key activator of the complement system’s alternative pathway (“APC”), 
and we believe that we are the first to make this and related discoveries associated with the APC. The complement 
system is part of the immune system’s innate response, and the APC is considered the amplification loop within the 
complement system. MASP-3 is responsible for the conversion of pro-factor D to factor D; converted factor D is 
necessary for the activation of the APC. Based on our alternative pathway-related discoveries, we have expanded our 
intellectual property position to protect our inventions stemming from these discoveries beyond MASP-2 associated 

7 

inhibition of the lectin pathway to include inhibition of the alternative pathway. Our current primary focus in this 
program is developing MASP-3 inhibitors for the treatment of disorders related to the APC. We believe that MASP-3 
inhibitors have the potential to treat patients suffering from a wide range of diseases and conditions, including: 
paroxysmal nocturnal hemoglobinuria (“PNH”); multiple sclerosis; neuromyelitis optica; age-related macular 
degeneration; Alzheimer’s disease; systemic lupus erythematosus; diabetic retinopathy; chronic obstructive pulmonary 
disease; antineutrophil cytoplasmic antibody-associated vasculitis; anti-phospholipid syndrome; atherosclerosis; 
myasthenia gravis and others. Our OMS906 monoclonal antibody program has generated positive data in a well-
established animal model associated with PNH as well as strong pharmacodynamic activity in non-human primates. The 
program has also generated positive data in a well-established animal model of arthritis.  

In September 2020 we began enrollment and dosing in a placebo-controlled, double-blind, single-ascending-dose 

and multiple-ascending-dose Phase 1 clinical trial to evaluate the safety, tolerability, pharmacodynamics and 
pharmacokinetics of OMS906. We have completed all of the intravenous dosing cohorts in the single-ascending-dose 
study and expect to begin subcutaneous dosing in March 2021. Initial data from the Phase 1 trial are expected in the 
second quarter of 2021. 

Licensing Arrangements. We jointly own and hold worldwide exclusive license rights related to therapeutic 
applications for inhibiting MASP-3 from the University of Leicester. For a more detailed description of these licenses, 
see “License and Development Agreements” below. 

MASP Inhibitor Preclinical Programs 

Other MASP Inhibitor Preclinical Programs 

We have generated positive preclinical data from MASP-2 inhibition in in vivo models of AMD, myocardial 

infarction, diabetic neuropathy, stroke, ischemia-reperfusion injury, and other diseases and disorders. 

We are also developing a longer-acting second generation antibody targeting MASP-2, which we are targeting for 

initiation of clinical trials in early 2022. Development efforts are also directed to a small-molecule inhibitor of MASP-2 
designed for oral administration, as well as small-molecule inhibitors of MASP-3 and bispecific small- and large-
molecule inhibitors of MASP-2/-3. 

Other Clinical Programs 

PDE7 Program - OMS527 

Overview. Our PDE7 program is based on our discoveries of previously unknown links between PDE7 and any 
addiction or compulsive disorder, and between PDE7 and any movement disorders, such as Parkinson’s disease. PDE7 
appears to modulate the dopaminergic system, which plays a significant role in regulating both addiction and movement. 
We believe that PDE7 inhibitors could be effective therapeutics for the treatment of addictions and compulsions as well 
as for movement disorders. Data generated in preclinical studies support the use of PDE7 inhibitors in both of these 
therapeutic areas. 

In September 2019, we reported positive results from our completed Phase 1 clinical trial designed to assess the 
safety, tolerability and pharmacokinetics of the compound in healthy subjects. In the double blind, randomized Phase 1 
study, the study drug, referred to as OMS182399, met the primary endpoints of safety and tolerability and showed a 
favorable and dose-proportional pharmacokinetic profile supporting once-daily dosing. There was no apparent food 
effect on plasma exposure to OMS182399. Continued clinical development in our PDE7 program is subject to allocation 
of financial and other resources, which are currently prioritized for other programs. 

Exclusive License Agreement with Daiichi Sankyo Co., Ltd. We hold an exclusive license to certain PDE7 inhibitors 
claimed in patents and pending patent applications owned by Daiichi Sankyo Co., Ltd. (“Daiichi Sankyo”), as successor-
in-interest to Asubio Pharma Co., Ltd., or, for use in the treatment of movement, addiction and compulsive disorders as 

8 

well as other specified indications. For a more detailed description of our agreement with Daiichi Sankyo, see “License 
and Development Agreements” below. 

PPARγ Program - OMS405 

Overview. In our peroxisome proliferator-activated receptor gamma (“PPARγ”) program, we have engaged in 
development of proprietary compositions that include PPARγ agonists for the treatment and prevention of addiction to 
substances of abuse, which may include opioids, nicotine and alcohol. We believe that Omeros is the first to demonstrate 
a link between PPARγ and addiction disorders. Data from clinical studies and from animal models of addiction suggest 
that PPARγ agonists could be efficacious in the treatment of a wide range of addictions. 

Clinical trials. Our collaborators at The New York State Psychiatric Institute have completed two Phase 2 clinical 

trials related to our PPARγ program. These studies evaluated a PPARγ agonist, alone or in combination with other 
agents, for treatment of addiction to heroin and to nicotine. The published results of the heroin study demonstrated that, 
although not altering the reinforcing or positive subjective effects of heroin, the PPARγ agonist significantly reduced 
heroin craving and overall anxiety. The National Institute on Drug Abuse provided substantially all of the funding for 
these clinical trials and solely oversaw the conduct of these trials. We have the right or expect to be able to reference the 
data obtained from these studies for subsequent submissions to FDA and continue to retain all other rights in connection 
with the PPARγ program. We have also reported positive results (i.e., decreased cravings and protection of brain white 
matter) from a Phase 2 clinical trial conducted by an independent investigator evaluating the effects of a PPARγ agonist 
in patients with cocaine use disorder. 

An investigator-sponsored study on the prevention of relapse following treatment of cocaine use disorder is 
expected to begin enrolling in March 2021. The study is funded by the National Institute on Drug Abuse (“NIDA”). 

Patent Assignment Agreement with Roberto Ciccocioppo, Ph.D. We acquired the patent applications and related 

intellectual property rights for our PPARγ program in February 2009 from Roberto Ciccocioppo, Ph.D., of the 
Università di Camerino, Italy, pursuant to a patent assignment agreement. For a more detailed description of our 
agreement with Dr. Ciccocioppo, see “License and Development Agreements” below. 

Preclinical Programs and Platforms 

GPCR Platform 

Overview. GPCRs, which are cell surface membrane proteins involved in mediating both sensory and nonsensory 
functions, comprise one of the largest families of proteins in the genomes of multicellular organisms. Sensory GPCRs 
are involved in the perception of light, odors, taste and sexual attractants. Non-sensory GPCRs are involved in 
metabolism, behavior, reproduction, development, hormonal homeostasis and regulation of the central nervous system. 
The vast majority of GPCR drug targets are non-sensory. Although GPCRs form a super-family of receptors, individual 
GPCRs display a high degree of specificity and affinity for the functionally active molecules, or ligands, that bind to a 
given receptor. Ligands can either activate the receptor (agonists) or inhibit it (antagonists and inverse agonists). When 
activated by its ligand, the GPCR interacts with intracellular G proteins, resulting in a cascade of signaling events inside 
the cell that ultimately leads to the particular function linked to the receptor. Without a known ligand, there is no 
template from which medicinal chemistry efforts can be readily initiated, nor a means to identify the GPCR’s signaling 
pathway and, therefore, drugs are very difficult to develop against orphan GPCRs. “Unlocking” these orphan GPCRs by 
identifying one or more of their respective ligands could lead to the development of drugs that act at these new targets. 

To our knowledge, Omeros’ technology is the first commercially viable technology capable of identifying ligands of 

orphan GPCRs in high throughput. We have developed a proprietary cellular redistribution assay (“CRA”), which we 
use in a high-throughput manner to identify synthetic ligands, including antagonists, agonists and inverse agonists, that 
bind to and affect the function of orphan GPCRs. We have screened Class A orphan GPCRs against our small-molecule 
chemical libraries using the CRA. As of December 31, 2020, we had identified and confirmed compounds that interact 
with 54 of the 81 Class A orphan GPCRs linked to a wide range of indications including cancer as well as metabolic, 
cardiovascular, immunologic, inflammatory and central nervous system disorders.  

9 

One of our priorities in this program is GPR174, which is involved in the modulation of the immune system. In ex 

vivo human studies, our small-molecule inhibitors targeting GPR174 upregulate the production of cytokines, block 
multiple checkpoints and tumor promoters, and suppress regulatory T-cells. Based on our data, we believe that GPR174 
controls a major pathway in cancer and modulation of the receptor could provide a seminal advance in immuno-
oncologic treatments for a wide range of tumors. Our recent discoveries suggest a new approach to cancer 
immunotherapy that targets inhibition of GPR174 and can be combined with and significantly improve the tumor-killing 
effects of adenosine pathway inhibitors. These discoveries include (1) identification of cancer-immunity pathways 
controlled by GPR174, (2) the identification of phosphatidylserine as a natural ligand for GPR174, (3) a collection of 
novel small-molecule inhibitors of GPR174 and (4) a synergistic enhancement of “tumor-fighting” cytokine production 
by T cells following the combined inhibition of both GPR174 and the adenosine pathway, another key metabolic 
pathway that regulates tumor immunity. In November 2019, we announced that our studies in mouse models of 
melanoma and colon carcinoma found that GPR174-deficiency resulted in significantly reduced tumor growth and 
improved survival of the animals versus normal mice. We are developing both small-molecule and antibody inhibitors of 
GPR174 with the objective of moving compounds into human trials and exploring several of our other GPCR targets as 
well.  

We have also conducted in vitro and in vivo preclinical efficacy studies and engaged in compound optimization for a 

number of targets including GPR151, which is linked to schizophrenia, cognition and obesity, and GPR161, which is 
associated with triple negative breast cancer and various sarcomas. 

In addition to Class A orphan GPCRs, we have screened orphan and non-orphan Class B receptors. Class B GPCRs 
have large extracellular domains and their natural ligands are generally large peptides, making the development of orally 
active, small-molecule drugs against these receptors, such as glucagon and parathyroid hormone, a persistent challenge. 
Our CRA technology finds functionally active small molecules for GPCRs, which we believe could lead to the 
development of oral medications for many of the Class B GPCRs. While our focus to date has remained on Class A 
orphan GPCRs, we have identified and confirmed sets of compounds that interact selectively with, and modulate 
signaling of, a small subset of Class B GPCRs, namely glucagon-like peptide-1 receptor and parathyroid hormone 1 
receptor. 

GPCR Platform Funding Agreements with Vulcan Inc. and the Life Sciences Discovery Fund. In October 2010, we 
entered into funding agreements for our GPCR program with Vulcan Inc. and its affiliate, which we refer to collectively 
as Vulcan, and with the Life Sciences Discovery Fund Authority (“LSDF”), a granting agency of the State of 
Washington. For a more detailed description of these agreements, see “License and Development Agreements” below. 

Sales and Marketing 

We have retained all worldwide marketing and distribution rights to OMIDRIA, our product candidates and our 
development programs. This allows us to market and sell OMIDRIA and any product candidates that is approved in the 
future, either independently, through arrangements with third parties, or via some combination of these approaches. 

With respect to OMIDRIA in the U.S., we have developed our own internal marketing and sales capabilities and, as 
of December 31, 2020, we employed 63 sales and reimbursement team members. In July 2018 we placed OMIDRIA on 
the market in the EU on a limited basis, which maintained the ongoing validity of the European marketing authorization 
for OMIDRIA for a period of three years and we expect to continue to market the product within Europe on a limited 
basis for purposes of maintaining the marketing authorization. At this time we do not expect to generate, in the near-
term, significant sales of OMIDRIA outside of the U.S. 

Manufacturing, Supply and Commercial Operations 

OMIDRIA. We use third parties to produce, store and distribute OMIDRIA and currently do not own or operate 

manufacturing facilities. Our agreements with these third parties include confidentiality and intellectual property 
provisions to protect our proprietary rights related to OMIDRIA. We require manufacturers that produce APIs and 
finished drug products to operate in accordance with current Good Manufacturing Practices (“cGMPs”) and all other 
applicable laws and regulations. 

10 

We have an agreement with Hospira Worldwide, Inc. (“Hospira”), a wholly owned subsidiary of Pfizer, Inc., to 

provide commercial supply of OMIDRIA. Under the agreement with Hospira (the “Hospira OMIDRIA Agreement”), 
Hospira has agreed to manufacture and supply, and we have agreed to purchase, a minimum percentage of our 
requirements of OMIDRIA for commercial sales and clinical supplies for the development of additional therapeutic 
indications in the U.S. In addition, Hospira has agreed to manufacture and supply a portion of our requirements of 
OMIDRIA in the EU, with there being no minimum purchase and supply requirement in the EU if the parties do not 
enter into such an amendment to the agreement. We have not yet entered into such an agreement with Hospira relating to 
the supply of OMIDRIA for the EU. The Hospira OMIDRIA Agreement expires in February 2022, but may be 
terminated prior to the end of its term upon the occurrence of certain specified events, including without limitation an 
uncured breach of the agreement or bankruptcy or dissolution of a party. Upon termination of the Hospira OMIDRIA 
Agreement, except in the case of termination for an uncured breach by Hospira, we will be required to purchase all of 
Hospira’s inventory of OMIDRIA and, if applicable, all work-in-progress inventory and to reimburse Hospira for all 
supplies purchased or ordered based on firm purchase orders or our estimates of its requirements of OMIDRIA. 

We have used multiple suppliers for the APIs for OMIDRIA in the past and we intend to leverage Hospira’s 

sourcing of APIs in the future under the Hospira OMIDRIA Agreement. Given the large amount of these APIs 
manufactured annually by these and other suppliers, and the quantities of these APIs that we have on hand, we anticipate 
that we will be capable of addressing our commercial API supply needs for OMIDRIA in the near-term. We have not yet 
signed commercial agreements with suppliers for the supply of all of our anticipated commercial quantities of these APIs 
for OMIDRIA, although we may elect to do so in the future. In addition to our supply agreement with Hospira, we have 
executed an agreement with a second manufacturing partner for supply of OMIDRIA. Work to bring the second 
manufacturer online is ongoing and we anticipate OMIDRIA to be available from this manufacturer beginning in 2021. 

In the U.S., we sell OMIDRIA through a limited number of wholesalers that distribute the product to ASCs and 
hospitals. Title transfers upon delivery of OMIDRIA to the wholesaler. We use a single third-party logistics provider to 
handle warehousing and final packaging of our commercial supply of OMIDRIA in the U.S. and to ship OMIDRIA to 
our wholesalers. Our third-party logistics provider also performs certain support services on our behalf. Virtually all of 
our revenues for the last three fiscal years were generated from OMIDRIA product sales in the U.S. Our four major 
distributors--AmerisourceBergen Corporation, Cardinal Health, Inc., McKesson Corporation and FFF Enterprises, Inc.--
together with entities under their common control each accounted for 10% or more, and nearly 100% in aggregate, of our 
total revenue in 2020. For additional information regarding our major customers, see Part II, Item 8, “Note 2—
Significant Accounting Policies” to our Consolidated Financial Statements in this Annual Report on Form 10 K 

Product Candidates. We have laboratories in-house for analytical method development, bioanalytical testing, 
formulation, stability testing and small-scale compounding of laboratory supplies of product candidates. We utilize 
contract manufacturers to produce sufficient quantities of product candidates for use in preclinical and clinical studies 
and to store and distribute our product candidates. We require manufacturers that produce APIs and finished drug 
products for clinical use to operate in accordance with cGMPs and all other applicable laws and regulations. We 
anticipate that we will rely on contract manufacturers to develop and manufacture our product candidates for commercial 
sale. We maintain agreements with potential and existing manufacturers that include confidentiality and intellectual 
property provisions to protect our proprietary rights related to our product candidates.  

In July 2019, we entered into a master services agreement with Lonza Biologics Tuas Pte. Ltd. (“Lonza”) for the 

commercial production of narsoplimab and for certain regulatory support and related services to be provided by Lonza 
from time to time. Under the agreement Lonza will manufacture narsoplimab pursuant to purchase orders issued in 
accordance with forecasts that we provide. We will purchase narsoplimab that meets agreed specifications in batches, 
with the price per batch varying according to the total number of batches ordered for serial production in a single 
manufacturing campaign. We are obligated to purchase a minimum number of batches annually beginning on a specified 
anniversary of the first commercial sale of narsoplimab in either the U.S. or EU. We may be obligated to pay certain fees 
to Lonza upon cancellation of purchase orders.  

The initial term of the agreement expires five years after the first commercial sale of narsoplimab in either the U.S. 

or EU and is subject to automatic renewal for an additional four-year term unless we provide notice of non-renewal at 
least three years prior to the end of the initial term. In addition, either party may terminate the agreement, subject to 

11 

applicable notice and cure periods under certain circumstances. Other than our agreement for commercial supply of 
narsoplimab, we have not yet entered into a commercial supply agreement for any of our product candidates. 

License and Development Agreements 

MASP Program. Under our exclusive license agreements with the University of Leicester and MRC, we have agreed 

to pay royalties to each of the University of Leicester and MRC that are a percentage of any proceeds we receive from 
the licensed MASP-2 technology during the terms of the agreements. Our exclusive license agreement with the 
University of Leicester, but not our agreement with the MRC, also applies to other MASPs. The continued maintenance 
of these agreements requires us to undertake development activities. We must pay low single-digit percentage royalties 
with respect to proceeds that we receive from products incorporating certain intellectual property within the licensed 
technology that are used, manufactured, directly sold or directly distributed by us, and we must pay royalties, in the 
range of a low single-digit percentage to a low double-digit percentage, with respect to proceeds we receive from 
sublicense royalties or fees that we receive from third parties to which we grant sublicenses to certain intellectual 
property within the licensed technology. We did not make any upfront payments for these exclusive licenses nor are 
there any milestone payments or reversion rights associated with these license agreements. We retain worldwide 
exclusive licenses from these institutions to develop and commercialize any intellectual property rights developed in the 
sponsored research. The term of each license agreement ends when there are no longer any pending patent applications, 
applications in preparation or unexpired issued patents related to any of the intellectual property rights we are licensing 
under the agreement. Both of these license agreements may be terminated prior to the end of their terms by us for 
convenience or by one party if the other party (1) breaches any material obligation under the agreement and does not 
cure such breach after notice and an opportunity to cure or (2) is declared or adjudged to be insolvent, bankrupt or in 
receivership and materially limited from performing its obligations under the agreement. 

In April 2010, we entered into an exclusive license agreement with Helion, pursuant to which we received a royalty-

bearing, worldwide exclusive license to all of Helion’s intellectual property rights related to MASP-2 antibodies, 
polypeptides and methods in the field of inhibition of mannan-binding lectin-mediated activation of the complement 
system for the prevention, treatment or diagnosis of any disease or condition. We are obligated to make remaining 
development and sales milestone payments to Helion of up to approximately $5.4 million upon the achievement of 
certain events, such as receipt of marketing approval, and reaching specified sales milestones. We are obligated to pay 
Helion a low single-digit percentage royalty on net sales of a MASP-2 inhibitor product covered by the patents licensed 
under the agreement. The term of the agreement continues so long as there is a valid, subsisting and enforceable claim in 
any patents or patent applications covered by the agreement. The agreement may be terminated sooner by either party 
following a material breach of the agreement by the other party that has not been cured within 90 days. 

PPARγ. We acquired the patent applications and related intellectual property rights for our PPARγ program in 
February 2009 from Roberto Ciccocioppo, Ph.D. of the Università di Camerino, Italy, pursuant to a patent assignment 
agreement. In February 2011, we amended the agreement to include all intellectual property rights, including patent 
applications, related to nutraceuticals that increase PPARγ activity. Under the amended agreement, we have agreed to 
pay Dr. Ciccocioppo a low-single digit percentage royalty on net sales of any products that are covered by any patents 
that issue from the patent applications that we acquired from him. In addition, if we grant any third parties rights to 
manufacture, sell or distribute any such products, we must pay to Dr. Ciccocioppo a percentage of any associated fees 
we receive from such third parties in the range of low single-digits to low double-digits depending on the stage of 
development at which such rights are granted. We have also agreed to make total milestone payments of up to 
$3.8 million to Dr. Ciccocioppo upon the occurrence of certain development events, such as patient enrollment in a 
Phase 1 clinical trial and receipt of marketing approval of a product candidate covered by any patents that issue from the 
patent applications that we acquired from him. If we notify Dr. Ciccocioppo that we have abandoned all research and 
development and commercialization efforts related to the patent applications and intellectual property rights we acquired 
from him, Dr. Ciccocioppo has the right to repurchase those assets from us at a price equal to a double-digit percentage 
of our direct and indirect financial investments and expenditures in such assets. If he does not exercise his right to 
repurchase those assets within a limited period of time by paying the purchase price, we will have no further obligations 
to sell those assets to Dr. Ciccocioppo. The term of our agreement with Dr. Ciccocioppo ends when there are no longer 
any valid and enforceable patents related to the intellectual property rights we acquired from him, provided that either 
party may terminate the agreement earlier in case of an uncured breach by the other party. Under the terms of the 

12 

agreement, we have agreed to pay a portion of the payments due to Dr. Ciccocioppo to the Università di Camerino 
without any increase to our payment obligations. 

PDE7. Under an agreement with Daiichi Sankyo, we hold an exclusive worldwide license to PDE7 inhibitors 

claimed in certain patents and pending patent applications owned by Daiichi Sankyo for use in the treatment of 
(1) movement disorders and other specified indications, (2) addiction and compulsive disorders and (3) all other diseases 
except those related to dermatologic conditions. Under the agreement, we agreed to make milestone payments to Daiichi 
Sankyo of up to an aggregate total of $33.5 million upon the achievement of certain events in each of these three fields; 
however, if only one of the three indications is advanced through the milestones, the total milestone payments would be 
$23.5 million. The milestone payment events include successful completion of preclinical toxicology studies; dosing of 
human subjects in Phase 1, 2 and 3 clinical trials; receipt of marketing approval of a PDE7 inhibitor product candidate; 
and reaching specified sales milestones. In addition, Daiichi Sankyo is entitled to receive from us a low single-
digit percentage royalty of any net sales of a PDE7 inhibitor licensed under the agreement by us and/or our 
sublicensee(s) provided that, if the sales are made by a sublicensee, then the amount payable by us to Daiichi Sankyo is 
capped at an amount equal to a low double-digit percentage of all royalty and specified milestone payments received by 
us from the sublicensee. 

The term of the agreement with Daiichi Sankyo continues so long as there is a valid, subsisting and enforceable 
claim in any patents covered by the agreement. The agreement may be terminated sooner by us, with or without cause, 
upon 90 days advance written notice or by either party following a material breach of the agreement by the other party 
that has not been cured within 90 days or immediately if the other party is insolvent or bankrupt. Daiichi Sankyo also has 
the right to terminate the agreement if we and our sublicensee(s) cease to conduct all research, development and/or 
commercialization activities for a PDE7 inhibitor covered by the agreement for a period of six consecutive months, in 
which case all rights held by us under Daiichi Sankyo’s patents will revert to Daiichi Sankyo. 

GPCR Platform Funding Agreements with Vulcan Inc. and the Life Sciences Discovery Fund. In October 2010, we 

entered into funding agreements for our GPCR program with Vulcan and LSDF. We received $20.0 million and $5.0 
million, respectively, under the agreements with Vulcan and LSDF. Under these agreements, we have agreed to pay 
Vulcan and LSDF tiered percentages of the net proceeds, if any, that we derive from the GPCR program. The percentage 
rates of net proceeds payable to Vulcan and LSDF decrease as the cumulative net proceeds reach specified thresholds, 
and the blended percentage rate payable to Vulcan and LSDF in the aggregate is in the mid-teens with respect to the first 
approximately $1.5 billion of cumulative net proceeds that we receive from our GPCR program. If we receive 
cumulative net proceeds in excess of approximately $1.5 billion, the percentage rate payable to Vulcan and LSDF in the 
aggregate decreases to one percent. An acquirer of the assets in our GPCR program may be required, and an acquirer of 
our company would be required, to assume all of our payment and other obligations under our agreements with Vulcan 
and LSDF. 

Under our agreement with Vulcan, we granted Vulcan a security interest in our personal property related to the 

GPCR program, other than intellectual property, which security interest is junior to any existing or future security 
interests granted in connection with a financing transaction and which will be released automatically after Vulcan 
receives $25.0 million under the agreement. We also agreed not to grant any liens on intellectual property related to the 
GPCR program without Vulcan’s consent, subject to specified exceptions. These restrictions could limit our ability to 
pursue business opportunities involving the GPCR program or reduce the price that a potential buyer would pay for the 
GPCR assets. If we default under our agreement with Vulcan, in certain circumstances Vulcan may, subject to the rights 
of any holders of senior security interests, take control of such pledged assets. If we are liquidated, Vulcan’s right to 
receive any payments then due under our agreement would be senior to the rights of the holders of our common stock to 
receive any proceeds from the liquidation of our GPCR program assets. 

The term of our agreement with Vulcan is 35 years, provided that the term will automatically extend until the 
cumulative net proceeds that we receive from the GPCR program are approximately $1.5 billion. The term of our 
agreement with LSDF expires on the six-month anniversary following the last date that we deliver a report related to our 
incurrence of grant-funded expenses described in the agreement, provided that certain obligations will survive the 
expiration of the term. The term of our payment obligations to LSDF is the same as that under our agreement with 
Vulcan. 

13 

OMIDRIA. We entered into settlement agreements and consent judgments with (1) Par Pharmaceutical, Inc. and its 

subsidiary, Par Sterile Products, LLC (collectively, “Par”) and (2) Lupin Ltd. and Lupin Pharmaceuticals, Inc. 
(collectively, “Lupin”) in October 2017 and May 2018, respectively.  

Under the terms of the settlement agreements and consent judgments, Par and Lupin are each prohibited from 
launching a generic version of OMIDRIA prior to a specified entry date. Par’s entry date is the earlier of (1) April 1, 
2032 or (2) the date on which we or a third-party, through licensing or any future final legal judgment, should one ever 
exist, with respect to our Orange Book listed patents, is able to launch a generic version of OMIDRIA. Lupin’s entry 
date is the earlier of (A) April 1, 2032 if Par has forfeited its six month first-ANDA filer exclusivity, (B) October 1, 2032 
if Par has not forfeited its six month first-ANDA filer exclusivity, or (C) a date on which we or a third party (other than 
Par), through licensing of, any future final legal judgment regarding, or the delisting, abandonment or expiration of our 
U.S. OMIDRIA patents, is able to launch a generic version of OMIDRIA. Under the settlement agreements, we granted 
each of Par and Lupin a non-exclusive, non-sublicensable license to make, sell and distribute a generic version of 
OMIDRIA between their applicable entry dates and the latest expiration of our U.S. patents related to OMIDRIA (i.e., 
October 23, 2033). During this period, Par and Lupin, as applicable, are each required to pay us a royalty equal to 15% 
of net sales of its generic version of OMIDRIA. 

Competition 

Overview. The pharmaceutical and biotechnology industry is highly competitive and characterized by a number of 

established, large pharmaceutical and biotechnology companies as well as smaller companies like ours. We expect to 
compete with other pharmaceutical and biotechnology companies, and our competitors may: 

• 

• 

• 

• 

• 

develop and market products that are less expensive, more effective or safer than our future products; 

commercialize competing products before we can launch our products; 

operate larger research and development programs, possess greater manufacturing capabilities or have 
substantially greater financial resources than we do; 

initiate or withstand substantial price competition more successfully than we can; 

have greater success in recruiting skilled technical and scientific workers from the limited pool of available 
talent; 

•  more effectively negotiate third-party licenses and strategic relationships; and 

• 

take advantage of acquisition or other opportunities more readily than we can. 

We expect to compete for market share against large pharmaceutical and biotechnology companies, smaller 
companies that are collaborating with larger pharmaceutical companies, new companies, academic institutions, 
government agencies and other public and private research organizations. In addition, the pharmaceutical and 
biotechnology industry is characterized by rapid technological change. Because our research approach integrates many 
technologies, it may be difficult for us to remain current with the rapid changes in each technology. Further, our 
competitors may render our technologies obsolete by advancing their existing technological approaches or developing 
new or different approaches. If we fail to stay at the forefront of technological change, we may be unable to compete 
effectively. 

OMIDRIA. We are not aware of any product that directly competes with OMIDRIA and is FDA-approved for 
intraoperative delivery in irrigation solutions during surgical procedures; however, OMIDRIA could face competition 
from products that are delivered intraoperatively, but that do not include a non-steroidal anti-inflammatory agent, as well 
as from preoperative and postoperative treatments for mydriasis, pain or inflammation. Our primary competition for 
OMIDRIA comes from surgeons’ current practices, which may include use of products obtained from distributors or 

14 

compounding pharmacies at a relatively low cost. Title I (the “Compounding Quality Act”) of the Drug Quality and 
Security Act, which was enacted in November 2013, added Section 503B to the FDCA establishing a distinct category of 
drug compounders known as “outsourcing facilities.” Among other provisions, the Compounding Quality Act imposes 
restrictions on the materials that may be compounded at registered outsourcing facilities and traditional compounders 
and places conditions on the compounding of bulk substances. Surgeons may perceive that, since the enactment of the 
Compounding Quality Act, compounding pharmacies, particularly those that are registered as “outsourcing facilities,” 
are subject to rigorous regulatory oversight that assures the safety and manufacturing quality of compounded products, 
notwithstanding the relatively high frequency of recall events, warning letters and findings of unsanitary conditions 
issued by FDA following inspection of registered outsourcing facilities. In addition, we anticipate that there are some 
surgeons who do not use intraoperative mydriatics and may not agree with the value proposition of maintaining pupil 
dilation and inhibiting miosis during the procedure, or with the use of a nonsteroidal anti-inflammatory drug 
intraoperatively to inhibit inflammation, prevent miosis and reduce postoperative pain. Although we are not aware of 
any companies developing similar approaches for maintenance of intraoperative pupil size and postoperative pain 
reduction as an FDA-approved product, such strategies may develop. In Europe, an inexpensive mydriatic and local 
anesthetic combination product is available but, unlike OMIDRIA, this product does not include an anti-inflammatory 
agent. 

Product Candidates, Development Programs and Platforms. With respect to our development of therapeutics 

targeting complement-mediated disorders, there are multiple companies developing potential therapies targeting the 
complement system, although none of these potential therapies, to our knowledge, selectively inhibit the lectin pathway. 
Soliris® (eculizumab) and Ultomiris® (ravulizumab-cwvz) are monoclonal complement inhibitors administered 
intravenously and approved for commercial use with which our lead MASP-2 inhibitor, narsoplimab (OMS721), and/or 
our MASP-3 inhibitor OMS906 will compete, if either is approved for any indication(s) for which Soliris® and/or 
Ultomiris® are also approved. Alexion Pharmaceuticals, Inc., the manufacturer of Soliris® and Ultomiris®, initiated a 
Phase 3 trial of Ultomiris® for HSCT-TMA in the fourth quarter of 2020. 

We are aware of other companies attempting to de-orphanize orphan GPCRs. If any of these companies is able to 

de-orphanize an orphan GPCR before we unlock this receptor, we may be unable to establish an exclusive or 
commercially valuable intellectual property position around that orphan GPCR.  

Intellectual Property 

We have retained control of all worldwide manufacturing, marketing and distribution rights for OMIDRIA and each 

of our product candidates and programs. Some of our products and product candidates and programs are based on 
inventions and other intellectual property rights that we acquired through assignments, exclusive licenses or acquisitions 
described in further detail under “License and Development Agreements” below. 

As of February 10, 2021, we owned or held worldwide exclusive licenses to a total of 82 issued patents and 68 
pending patent applications in the U.S. and 1,161 issued patents and 582 pending patent applications in foreign markets 
directed to therapeutic compositions and methods related to our research and development programs. For each program, 
our decision to seek patent protection in specific foreign markets, in addition to the U.S., is based on many factors, 
including one or more of the following: our available resources, the size of the commercial market, the presence of a 
potential competitor or a contract manufacturer in the market and whether the legal authorities in the market effectively 
enforce patent rights. 

•  OMIDRIA-Ophthalmology. OMIDRIA is encompassed by our PharmacoSurgery patent portfolio. The relevant 

patents and patent applications in this portfolio are directed to combinations of agents, generic and/or 
proprietary to us or to others, drawn from therapeutic classes such as pain and inflammation inhibitory agents, 
mydriatic agents and agents that reduce intraocular pressure, delivered locally and intraoperatively to the site of 
ophthalmological procedures, including cataract and lens replacement surgery. As of February 10, 2021, we 
owned eight issued U.S. patents and three pending U.S. patent applications and 99 issued patents and 55 
pending patent applications in foreign markets that are directed to OMIDRIA. Our OMIDRIA patents have 
terms that will expire as late as October 23, 2033 and, if currently pending patent applications are issued, as late 
as November 30, 2035. 

15 

•  MASP-2 Program - Narsoplimab (OMS721). We hold worldwide exclusive licenses to rights in connection with 

MASP-2, the antibodies targeting MASP-2 and the therapeutic applications for those antibodies from the 
University of Leicester, MRC and Helion. As of February 10, 2021, we exclusively controlled 24 issued patents 
and 40 pending patent applications in the U.S., and 568 issued patents and 385 pending patent applications in 
foreign markets, related to our MASP-2 program. Our MASP-2 and narsoplimab patents have terms that will 
expire as late as 2037 and, if currently pending patent applications are issued, as late as 2040. 

•  MASP-3 Program - OMS906. We own and exclusively control under a license from the University of Leicester 
all rights to methods of treating various disorders and diseases by inhibiting MASP-3. As of February 10, 2021, 
we exclusively controlled two issued patents and five pending patent applications in the U.S. and 81 issued and 
87 pending patent applications in foreign markets that are related to our MASP-3 program. 

•  PPARγ Program - OMS405. As of February 10, 2021, we owned two issued patents and one pending patent 

application in the U.S., and 35 issued patents and 11 pending patent applications in foreign markets, directed to 
our discoveries linking PPARγ and addictive disorders. 

•  PDE7 Program - OMS527. As of February 10, 2021, we owned two issued patents and one pending patent 

application in the U.S., and 61 issued patents and three pending patent applications in foreign markets directed 
to our discoveries linking PDE7 to movement disorders, as well as one issued patent and two pending patent 
applications in the U.S., and 49 issued patents and 13 pending patent applications in foreign markets directed to 
the link between PDE7 and addiction and compulsive disorders. Additionally, under a license from Daiichi 
Sankyo, we exclusively control rights to three issued U.S. patents and 61 issued and one pending patent 
application in foreign markets that are directed to proprietary PDE7 inhibitors. For a more detailed description 
of our agreement with Daiichi Sankyo, see “License and Development Agreements” below. 

•  GPCR Platform. As of February 10, 2021, we owned seven issued patents and 12 pending patent applications in 
the U.S., and 56 issued patents and one pending patent application in foreign markets, which are directed to 
previously unknown links between specific molecular targets in the brain and a series of CNS disorders, to our 
CRA and to other research tools that are used in our GPCR program, and to orphan GPCRs and other GPCRs 
for which we have identified functionally interacting compounds using our CRA. Two of the pending patent 
applications in the U.S. and the pending patent application in foreign markets are directed to GPR174.    

All of our employees enter into our standard employee proprietary information and inventions agreement, which 

includes confidentiality provisions and provides us ownership of all inventions and other intellectual property made by 
our employees that pertain to our business or that relate to our employees’ work for us or that result from the use of our 
resources. Our commercial success will depend in part on obtaining and maintaining patent protection and trade secret 
protection of the use, formulation and structure of our products and product candidates and the methods used to 
manufacture them, as well as on our ability to defend successfully these patents against third-party challenges. Our 
ability to protect our products and product candidates from unauthorized making, using, selling, offering to sell or 
importing by third parties is dependent on the extent to which we have rights under valid and enforceable patents that 
cover these activities. 

The patent positions of pharmaceutical, biotechnology and other life sciences companies can be highly uncertain 

and involve complex legal and factual questions for which important legal principles remain unresolved. No consistent 
policy regarding the breadth of claims allowed in biotechnology patents has emerged to date in the U.S., and tests used 
for determining the patentability of patent claims in all technologies are in flux. The pharmaceutical, biotechnology and 
other life sciences patent situation outside the U.S. is even more uncertain. Changes in either the patent laws or in 
interpretations of patent laws in the U.S. and other countries may diminish the value of our intellectual property. 
Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in the patents that we own or have 
licensed or in third-party patents. 

We sell OMIDRIA under trademarks that we consider in the aggregate to be important to our operations. We have 

registered, and intend to maintain, the trademarks “OMEROS”, “OMIDRIA”, “OMIDRIASSURE” and 
“PHARMACOSURGERY” with the U.S. Patent and Trademark Office in connection with the products and services we 

16 

offer. We are not aware of any material claims of infringement or other challenges to our right to use the “OMEROS,” 
“OMIDRIA,” “OMIDRIASSURE” or “PHARMACOSURGERY” trademarks in the U.S. 

Government Regulation 

Government authorities in the U.S., the EU and other countries extensively regulate the research, development, 

testing, manufacture, labeling, promotion, advertising, distribution, marketing, and export and import of drug and 
biologic products such as OMIDRIA and the product candidates that we are developing. Failure to comply with 
applicable requirements, both before and after receipt of regulatory approval, may subject us, our third-party 
manufacturers, and other partners to administrative and judicial sanctions, such as warning letters, product recalls, 
product seizures, a delay in approving or refusal to approve pending applications, civil and other monetary penalties, 
total or partial suspension of production or distribution, injunctions, and/or criminal prosecutions. 

In the U.S., our products and product candidates are regulated by FDA as drugs or biologics under the FDCA and 

implementing regulations and under the Public Health Service Act (“PHSA”). In Europe, our products and product 
candidates are regulated by the EMA and national medicines regulators under the rules governing medicinal products in 
the EU as well as national regulations in individual countries. OMIDRIA has received marketing approval from FDA 
and from the applicable regulatory authorities in the EU. Our product candidates are in various stages of testing and none 
of our product candidates has received marketing approval from FDA or the applicable regulatory authorities in the EU. 

The steps required before a product may be approved for marketing by FDA, or the applicable regulatory authorities 

outside of the U.S., typically include the following: 

• 

• 

• 

• 

• 

• 

• 

formulation development and manufacturing process development; 

preclinical laboratory and animal testing; 

submission to FDA of an Investigational New Drug application (“IND”) for human clinical testing, which must 
become effective before human clinical trials may begin; and in countries outside the U.S., a Clinical Trial 
Application (“CTA”), is filed according to the country’s local regulations; 

adequate and well-controlled human clinical trials to establish the efficacy and safety of the product for each 
indication for which approval is sought; 

adequate assessment of drug product stability to determine shelf life/expiry dating; 

in the U.S., submission to FDA of a New Drug Application (“NDA”), in the case of a drug product, or a BLA in 
the case of a biologic product and, in Europe, submission to the EMA or a national regulatory authority of an 
MAA; 

satisfactory completion of inspections of one or more clinical sites at which clinical trials with the product were 
carried out and of the manufacturing facility or facilities at which the product is produced to assess compliance 
with Good Clinical Practices (“GCPs”), and cGMPs; and 

•  FDA review and approval of an NDA or BLA, or review and approval of an MAA by the applicable regulatory 

authorities in the EU. 

Manufacturing. Manufacturing of drug products for use in clinical trials must be conducted according to relevant 

national and international guidelines, for example, cGMP. Process and formulation development are undertaken to 
design suitable routes to manufacture the drug substance and the drug product for administration to animals or humans. 
Analytical development is undertaken to obtain methods to quantify the potency, purity and stability of the drug 
substance and drug product as well as to measure the amount of the drug substance and its metabolites in biological 
fluids, such as blood. 

17 

Preclinical Tests. Preclinical tests include laboratory evaluations and animal studies to assess efficacy, toxicity and 
pharmacokinetics. The results of the preclinical tests, together with manufacturing information, analytical data, clinical 
development plan, and other available information are submitted as part of an IND or CTA. 

The IND/CTA Process. An IND or CTA must become effective before human clinical trials may begin. INDs are 
extensive submissions including, among other things, the results of the preclinical tests, together with manufacturing 
information and analytical data.  In addition to including the results of the preclinical studies, the IND will also include 
one or more protocols for proposed clinical trials detailing, among other things, the objectives of the clinical trial, the 
parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. An IND will become effective 
30 days after receipt by FDA unless, before that time, FDA raises concerns or questions and imposes a clinical hold. In 
that event, the IND sponsor and FDA must resolve any outstanding FDA concerns or questions before the clinical hold is 
lifted and clinical trials can proceed. Similarly, a CTA must be cleared by the local independent ethics committee and 
competent authority prior to conducting a clinical trial in the country in which it was submitted. There can be no 
assurance that submission of an IND or CTA will result in authorization to commence clinical trials. Once an IND or 
CTA is in effect, there are certain reporting requirements. 

Clinical Trials. Clinical trials involve the administration of the investigational product to human subjects under the 
supervision of qualified personnel and must be conducted in accordance with local regulations and GCPs. Clinical trials 
are conducted under protocols detailing, for example, the parameters to be used in monitoring patient safety and the 
efficacy criteria, or endpoints, to be evaluated. Each trial must be reviewed and approved by an independent institutional 
review board or ethics committee for each clinical site at which the trial will be conducted before it can begin. Clinical 
trials are typically conducted in three defined phases, but the phases may overlap or be combined: 

•  Phase 1 usually involves the initial administration of the investigational product to human subjects, who may or 

may not have the disease or condition for which the product is being developed, to evaluate the safety, dosage 
tolerance, pharmacodynamics and, if possible, to gain an early indication of the effectiveness of the product. 

•  Phase 2 usually involves trials in a limited patient population with the disease or condition for which the 

product is being developed to evaluate appropriate dosage, to identify possible adverse side effects and safety 
risks, and to evaluate preliminarily the effectiveness of the product for specific indications. 

•  Phase 3 clinical trials usually further evaluate and confirm effectiveness and test further for safety by 

administering the product in its final form in an expanded patient population. 

We, our product development partners, institutional review boards or ethics committees, FDA or other regulatory 
authorities may suspend or terminate clinical trials at any time on various grounds, including a belief that the subjects are 
being exposed to an unacceptable health risk. 

Disclosure of Clinical Trial Information. Sponsors of clinical trials of certain FDA-regulated products, including 

prescription drugs, are required to register and disclose certain clinical trial information on a public website maintained 
by the U.S. National Institutes of Health. Information related to the product, patient population, phase of investigation, 
study sites and investigator, and other aspects of the clinical trial is made public as part of the registration. Sponsors are 
also obligated to disclose the results of these trials after completion. Disclosure of the results of these trials can be 
delayed for up to two years if the sponsor certifies that it is seeking approval of an unapproved product or that it will file 
an application for approval of a new indication for an approved product within one year. Clinical trials conducted in 
European countries are required to be registered at a similar public database maintained and overseen by European 
health authorities. Competitors may use this publicly available information to gain knowledge regarding the design and 
progress of our development programs. 

The Application Process. If the necessary clinical trials are successfully completed, the results of the preclinical 
trials and the clinical trials, together with other detailed information, including information on the manufacture and 
composition of the product, are submitted to FDA in the form of an NDA or a BLA, as applicable, and to the EMA or 
national regulators in the form of an MAA, requesting approval to market the product for a specified indication. In the 
EU, an MAA may be submitted to the EMA for review and, if the EMA gives a positive opinion, the EC may grant a 

18 

marketing authorization that is valid across the EU (centralized procedure). Alternatively, an MAA may be submitted to 
one or more national regulators in the EU according to one of several national or decentralized procedures. The type of 
submission in Europe depends on various factors and must be cleared by the appropriate authority prior to submission. 
For most of our product candidates, the centralized procedure will be either mandatory or available as an option. 

If the regulatory authority determines that the application is not acceptable, it may refuse to accept the application 
for filing and review, outlining the deficiencies in the application and specifying additional information needed to file 
the application. Notwithstanding the submission of any requested additional testing or information, the regulatory 
authority ultimately may decide that the proposed product is not safe or effective, or that the application does not 
otherwise satisfy the criteria for approval. In the U.S., to support an approval an NDA must demonstrate, among other 
things, that the proposed drug product is safe and effective, has a favorable benefit-risk profile, is manufactured in a way 
that preserves its identity, strength, purity and potency, and that its labeling is adequate and not false or misleading. A 
similar standard exists for BLAs. Before approving an NDA or BLA, or an MAA, FDA or the EMA, respectively, may 
inspect one or more of the clinical sites at which the clinical studies were conducted to ensure that GCPs were followed 
and may inspect facilities at which the product is manufactured to ensure satisfactory compliance with cGMP. The FDA 
may refer the NDA or BLA to an advisory committee for review 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 generally follows such recommendation. In addition, even if a product candidate satisfied its endpoints 
with statistical significance during clinical trials, FDA could determine that the overall balance of risks and benefits for 
the product candidate is not adequate to support approval, or only justifies approval for a narrow set of clinical uses 
and/or subject to restricted distribution or other burdensome post-approval requirements or limitations. If approval is 
obtained changes to the approved product such as adding new indications, manufacturing changes, or additional labeling 
claims will require submission of a supplemental application, referred to as a variation in the EU, or, in some instances, a 
new application, for further review and approval. The testing and approval process requires substantial time, effort, and 
financial resources, and we cannot be sure that any future approval will be granted on a timely basis, if at all. 

Some of our drug products may be eligible for NDA submissions to FDA for approval under the 

Section 505(b)(2) process. Section 505(b)(2) applications are a type of NDA that may be submitted for drug products 
that represent a modification, such as a new indication or new dosage form, of a previously approved drug. 
Section 505(b)(2) applications may rely on FDA’s previous findings for the safety and effectiveness of the previously 
approved drug along with additional clinical data and information obtained by the 505(b)(2) applicant to support the 
modification of the previously approved drug. Preparing Section 505(b)(2) applications may be less costly and time-
consuming than preparing an NDA that is based entirely on new data and information. 

Some of our product candidates, such as those from our MASP-2 and MASP-3 programs, are considered biologics 

because they are derived from natural sources as opposed to being chemically synthesized. The added complexity 
associated with manufacturing biologics may result in additional monitoring of the manufacturing process and product 
changes. 

In addition, we, our suppliers and our contract manufacturers are required to comply with extensive regulatory 

requirements both before and after approval. For example, we must establish a pharmacovigilance system and are 
required to report adverse reactions and production problems, if any, to the regulatory authorities. We must also comply 
with certain requirements concerning advertising and promotion for our products. The regulatory authorities may impose 
specific obligations as a condition of the marketing authorization, such as additional safety monitoring, or the conduct of 
additional clinical trials or post-marketing safety studies, or the imposition of a Risk Evaluation and Mitigation Strategy 
(“REMS”), which could include significant restrictions on distribution or use of the product. Also, quality control and 
manufacturing procedures must continue to conform to cGMPs after approval. Accordingly, manufacturers must 
continue to expend time, money, and effort in all areas of regulatory compliance, including production and quality 
control to comply with cGMPs. In addition, discovery of problems such as safety issues may result in changes in 
labeling or restrictions on a product manufacturer or marketing authorization holder, including removal of the product 
from the market. 

Fast-Track and Priority Review Designations. Section 506(b) of the FDCA provides for the designation of a drug as 
a fast-track product if it is intended, whether alone or in combination with one or more other drugs, for the treatment of a 

19 

serious or life-threatening disease or condition, and it demonstrates the potential to address unmet medical needs for 
such a disease or condition. A program with fast-track status is afforded greater access to FDA for the purpose of 
expediting the product’s development, review and potential approval. Many products that receive fast-track designation 
are also considered appropriate to receive priority review, and their respective applications may be accepted by FDA as a 
rolling submission in which portions of an NDA or BLA are reviewed before the complete application is submitted. 
Together, these may reduce time of development and FDA review time. In Europe, products that are considered to be of 
major public health interest are eligible for accelerated assessment, which shortens the review period. The grant of fast-
track status, priority review or accelerated assessment does not alter the standard regulatory requirements for obtaining 
marketing approval. 

Breakthrough Therapy Designation. In 2012, Congress enacted the Food and Drug Administration Safety and 
Innovation Act. This law established a regulatory process allowing for increased interactions with FDA with the goal of 
expediting development and review of products designated as “breakthrough therapies.” A product may be designated as 
a breakthrough therapy if it is intended, either alone or in combination with one or more other products, to treat a serious 
or life-threatening disease or condition and preliminary clinical evidence indicates that the product may demonstrate 
substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial 
treatment effects observed early in clinical development. The FDA may take certain actions with respect to breakthrough 
therapies, including holding meetings with the sponsor throughout the development process; providing timely advice to 
the product sponsor regarding development and approval; involving more senior staff in the review process; assigning a 
cross-disciplinary project lead for the review team; and taking other steps to design the clinical trials in an efficient 
manner. 

Accelerated Approval. The FDA may grant accelerated approval to a product for a serious or life-threatening 

condition that provides a meaningful therapeutic advantage to patients over existing treatments based upon a 
determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit. 
The FDA may also grant accelerated approval for such a condition when the product has an effect on an intermediate 
clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality and that is reasonably 
likely to predict an effect on irreversible morbidity or mortality or other clinical benefit. In both cases, FDA must take 
into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. 
Studies that are conducted to demonstrate a drug’s effect on a surrogate or intermediate clinical endpoint for accelerated 
approval must be adequate and well-controlled as required by the FDCA. 

Following accelerated approval, FDA requires that the company provide confirmatory evidence, which may include 

certain adequate and well-controlled post-marketing clinical studies to verify and describe the clinical benefit of the 
product, and FDA may impose restrictions on distribution to assure safe use. Confirmatory studies are typically required 
to be underway at the time of the accelerated approval. If the required confirmatory studies fail to verify the clinical 
benefit of the drug, or if the applicant fails to perform the required confirmatory studies with due diligence, FDA may 
withdraw approval of the drug under streamlined procedures in accordance with the Agency’s regulations. The Agency 
may also withdraw approval of a drug if, among other things, other evidence demonstrates that the drug product is not 
shown to be safe or effective under its conditions of use. 

The EU also has accelerated approval programs. In the EU, a marketing authorization may be granted on the basis 

of less complete data than are normally required in certain “exceptional circumstances,” such as when the product’s 
indication is encountered so rarely that the applicant cannot reasonably be expected to provide comprehensive data. 
Alternatively, a conditional marketing authorization may be granted prior to obtaining the comprehensive clinical data 
required for a full MAA if a product fulfills an unmet medical need and the benefit to public health of the product’s 
immediate availability outweighs the risk inherent in the incomplete data. 

Orphan Drug Designation. Under the Orphan Drug Act (“ODA”), FDA may grant orphan drug designation to drugs 

or biologics intended to treat a rare disease or condition that affects fewer than 200,000 individuals in the U.S. or more 
than 200,000 individuals in the U.S. for which the cost of developing and making the product available in the U.S. for 
this type of disease or condition is not likely to be recovered from U.S. sales for that product. The granting of orphan 
designation does not alter the standard regulatory requirements (other than payment of certain fees and the applicability 
of certain pediatric assessment requirements), nor does it alter the standards or process for obtaining marketing approval. 

20 

The sponsor of a product that has an orphan drug designation qualifies for various development incentives specified in 
the ODA, including a tax credit of up to 25% of expenditures on qualified clinical testing for the orphan drug. 
Furthermore, if the orphan designated product subsequently receives the first FDA approval for the orphan indication, 
the product is entitled to an orphan drug exclusivity period, which means that FDA may not grant approval to any other 
application to market the same drug for the same indication for a period of seven years except in limited circumstances, 
such as a showing of clinical superiority to the product with orphan drug exclusivity for the protected indication. Orphan 
drug exclusivity does not prevent FDA from approving a different drug for the same disease or condition, or the same 
drug for a different disease or condition. The EU has a similar Orphan Drug program to that of the U.S., and it is 
administered through the EMA’s Committee for Orphan Medicinal Products. 

Pediatric Testing and Exclusivity. In the U.S., NDAs and BLAs are subject to both mandatory pediatric testing 

requirements and voluntary pediatric testing incentives in the form of exclusivity. An additional six months of 
exclusivity in the U.S. may be granted to a sponsor of an NDA or BLA if the sponsor conducts certain pediatric studies, 
which studies are conducted pursuant to a written request from FDA. This process is initiated when FDA issues a 
Written Request for pediatric studies to determine if the drug or biologic could have meaningful pediatric health 
benefits. If FDA determines that the sponsor has conducted the requested pediatric studies in accordance with the written 
request, then an additional six months of exclusivity may attach in the case of a drug to any other regulatory exclusivity 
or patent protection applicable to the drug and, in the case of a biologic, to any other regulatory exclusivity applicable to 
the biologic. The EU has a similar requirement and incentive for the conduct of pediatric studies according to the 
pediatric investigation plan, which must be adopted by the EMA before an MAA may be submitted. 

Expanded Access. “Expanded access” refers to the use of an investigational drug where the primary purpose is to 

diagnose, monitor, or treat a patient’s disease or condition rather than to collect information about the safety or 
effectiveness of a drug. There are three FDA-recognized categories of expanded access trials: expanded access for 
individual patients, including for emergency use; expanded access for intermediate-size patient populations; and 
expanded access for large patient populations under a treatment IND or treatment protocol. For all types of expanded 
access, FDA must determine prior to authorizing expanded access that: (1) the patient or patients to be treated have a 
serious or life-threatening disease or condition and there is no comparable or satisfactory alternative therapy; (2) the 
potential patient benefit justifies the potential risks of use and that the potential risks are not unreasonable in the context 
of the disease or condition to be treated; and (3) granting the expanded access will not interfere with the initiation, 
conduct, or completion of clinical studies in support of the drug’s approval. Only a licensed physician or the drug’s 
manufacturer may apply for expanded access. Manufacturers are not required to supply the investigational product for 
expanded access. The FDA has established streamlined processes for physicians to request individual patient expanded 
access whereby physicians can submit a single patient IND. In cases of individual patient emergency expanded access, 
physicians can receive FDA approval for access by phone and follow up with the abbreviated form. In addition, the 
sponsor of an expanded access IND must submit IND safety reports and, in the cases of protocols continuing for 
one year or longer, annual reports to FDA.  

U.S. Labeling, Marketing and Promotion. The FDA closely regulates the labeling, marketing and promotion of 
drugs. In general, our labeling and promotion must not be false or misleading in any particular, and claims that we make 
must be adequately substantiated. In addition, our approved labeling must include adequate directions to physicians for 
each intended use of our products. Failure to comply with these requirements can result in adverse publicity, warning 
letters, corrective advertising, injunctions and potential civil and criminal penalties. 

In addition to regulation by FDA, the research, manufacturing, distribution, sale and promotion of drug products in 

the U.S. are subject to regulation by various federal, state and local authorities, including CMS, other divisions of the 
U.S. Department of Health and Human Services (e.g., the Office of Inspector General), the U.S. Department of Justice, 
state Attorneys General, and other state and local government agencies. All of these activities are also potentially subject 
to federal and state consumer protection and unfair competition laws. Violations of these laws are punishable by prison 
sentences, criminal fines, administrative civil money penalties, and exclusion from participation in federal healthcare 
programs. 

There are also an increasing number of state laws that require manufacturers to make reports to states on pricing and 

marketing information or impose other special requirements for the sale and marketing of drug products. Many of these 

21 

laws contain ambiguities as to what is required to comply with the laws. In addition, federal and state “transparency 
laws” require manufacturers to track and report certain payments made to health care providers and, under some state 
laws, other information concerning our products. These laws may affect our sales, marketing and other promotional 
activities by imposing administrative and compliance burdens on us. In addition, our reporting actions could be subject 
to the penalty provisions of the pertinent state and federal authorities. 

Drug Supply Chain Security Act. Title II (the Drug Supply Chain Security Act (the “DSCSA”)), of the Drug Quality 

and Security Act imposes on manufacturers of certain pharmaceutical products new obligations related to product 
tracking and tracing, among others, which began a several-year phase-in process in 2015. Among the requirements of 
this legislation, manufacturers subject to the DSCSA are required to provide certain documentation regarding the drug 
product to trading partners to which product ownership is transferred, label drug product with a product identifier (i.e., 
serialize), respond to verification requests from trading partners, provide transaction documentation upon request by 
federal or state government entities, and keep certain records regarding the drug product. The transfer of information to 
subsequent product owners by manufacturers must be done electronically. For products and transactions falling within 
DSCSA’s scope, manufacturers are required to verify that purchasers of the manufacturers’ products are appropriately 
licensed. Further, under the DSCSA, covered manufacturers have drug product investigation, quarantine, disposition, 
and notification responsibilities for product that is reasonably believed or that credible evidence shows to be counterfeit, 
diverted, stolen, intentionally adulterated such that the product would result in serious adverse health consequences or 
death, the subject of fraudulent transactions or otherwise unfit for distribution such that they would be reasonably likely 
to result in serious health consequences or death. Anti-counterfeiting and serialization requirements similar to those 
under the DSCSA have also been adopted in the EU and became effective in February 2019. 

Foreign Regulatory Requirements. Outside of the U.S., our ability to conduct clinical trials or market our products 

will also depend on receiving the requisite authorizations from the appropriate regulatory authorities. The foreign 
regulatory approval processes include similar requirements and many of the risks associated with FDA and/or the EU 
approval process described above, although the precise requirements may vary from country to country. In the EU, once 
an MAA is granted, the product must be “placed on the market” in at least one EEA country within three years of the 
date of authorization. “Placed on the market” is defined as when the medicinal product is “released into the distribution 
chain,” i.e., out of the direct control of the marketing authorization holder. In July 2018, we placed OMIDRIA on the 
market in the EU, on a limited basis, which maintained the ongoing validity of the European marketing authorization for 
OMIDRIA. A marketing authorization will cease to be valid if a product previously placed on the market is no longer 
actually present on the market for three consecutive years and we expect to make OMIDRIA available in the European 
market on a limited basis to the extent necessary to continue the validity of our marketing authorization. 

Hatch-Waxman Act. In seeking approval for a drug through an NDA, applicants are required to list with FDA each 

patent with claims that cover the applicant’s drug or an approved method of use of the drug. Upon approval of a drug, 
each of the patents listed in the application for the drug is then published in FDA’s Approved Drug Products with 
Therapeutic Equivalence Evaluations, commonly known as the Orange Book. Drugs listed in the Orange Book can, in 
turn, be cited by potential competitors in support of approval of an ANDA or a 505(b)(2) application. In this case the 
original NDA, i.e., the pioneer drug, is known as the “listed” drug or “reference-listed” drug. An ANDA provides for 
marketing of a drug that has the same active ingredients and, in some cases (e.g., ophthalmology), also the same inactive 
ingredients, in the same strengths, route of administration and dosage form as the listed drug and has been shown 
through testing to be bioequivalent to the listed drug or receives a waiver from bioequivalence testing. ANDA applicants 
are generally not required to conduct or submit results of preclinical or clinical tests to prove the safety or effectiveness 
of their drug, other than the requirement for bioequivalence testing. Drugs approved in this way are considered 
therapeutically equivalent, and are commonly referred to as “generic equivalents” to the listed drug. These drugs then 
generally can be substituted by pharmacists under prescriptions written for the original listed drug. 

The ANDA or 505(b)(2) applicant is required to certify to FDA concerning any patents listed for the referenced 

approved drug in FDA’s Orange Book. Specifically, for each listed patent, the applicant must certify that: (1) the 
required patent information has not been filed; (2) the listed patent has expired; (3) the listed patent has not expired but 
will expire on a particular date and approval is sought after patent expiration; or (4) the listed patent is invalid, 
unenforceable or will not be infringed by the new drug. A certification that the new drug will not infringe the already 
approved drug’s listed patents or that such patents are invalid or unenforceable is called a Paragraph IV certification. If 

22 

the ANDA or 505(b)(2) applicant does not include a Paragraph IV certification, the ANDA or 505(b)(2) application will 
not be approved until all of the listed patents claiming the referenced drug have expired, except for any listed patents that 
only apply to uses of the drug not being sought by the ANDA or 505(b)(2) applicant. 

If the ANDA or 505(b)(2) applicant has made a Paragraph IV certification, the applicant must also send notice of a 
Paragraph IV Notice Letter to the NDA and patent holders once the ANDA or 505(b)(2) application has been accepted 
for filing by FDA. The NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice 
of the Paragraph IV Notice Letter. The filing of a patent infringement lawsuit within 45 days of the receipt of notice of a 
Paragraph IV Notice Letter automatically prevents FDA from approving the ANDA until the earlier of 30 months, 
expiration of the patent, settlement of the lawsuit, modification by a court or a decision in the infringement case that is 
favorable to the ANDA or 505(b)(2) applicant. 

The ANDA or 505(b)(2) application also will not be approved until any applicable non-patent exclusivity, such as 
exclusivity for obtaining approval of a new chemical entity, listed in the Orange Book for the reference-listed drug has 
expired. The U.S. Drug Price Competition and Patent Term Restoration Act of 1984, more commonly known as the 
Hatch-Waxman Act, provides a period of five years following approval of a drug containing no previously approved 
active moiety, during which ANDAs for generic versions of those drugs and 505(b)(2) applications referencing those 
drugs cannot be submitted unless the submission contains a Paragraph IV challenge to a listed patent, in which case the 
submission may be made four years following the original drug approval. The Hatch-Waxman Act also provides for a 
period of three years of exclusivity following approval of a listed drug that contains previously approved active 
ingredients but is approved in a new dosage form, route of administration or combination, or for a new use, the approval 
of which was supported by new clinical trials other than bioavailability studies that were essential to the approval and 
conducted by or for the sponsor. During those three years of exclusivity, FDA cannot grant approval of an ANDA or 
505(b)(2) application for the protected dosage form, route of administration or combination, or use of that listed drug. 

In December 2019, a piece of legislation referred to as the Creating and Restoring Equal Access to Equivalent 
Samples Act of 2019 (“CREATES Act”) was signed into law, which is intended to address the concern that some brand 
manufacturers have improperly denied generic and biosimilar product developers access to samples of brand products. 
The CREATES Act establishes a private cause of action that permits a generic or biosimilar product developer to sue the 
brand manufacturer to compel it to furnish the necessary samples on commercially reasonable, market-based terms. If 
the developer prevails, the court may grant the developer a monetary award up to the brand product’s revenue for the 
period of delay in providing samples. 

Biosimilars. The enactment of federal healthcare reform legislation in March 2010 provided a new pathway for 
approval of follow-on biologics (i.e., biosimilars) under the PHSA. FDA licensure of a biosimilar is dependent upon 
many factors, including a showing that the proposed biosimilar is “highly similar” to the reference product, 
notwithstanding minor differences in clinically inactive components, and has no clinically meaningful differences from 
the reference product in terms of safety, purity, and potency. The types of data ordinarily required in a biosimilar 
application to show high similarity include analytical data, animal studies (including toxicity studies), and clinical 
studies (including immunogenicity and pharmacokinetic/pharmacodynamic studies). A biosimilar must seek licensure 
for a condition of use for which the reference-listed product is licensed. 

Furthermore, the PHSA provides that for a biosimilar to be considered “interchangeable” (i.e., the biological 
product may be substituted for the reference product without the intervention of the health care provider who prescribed 
the reference product), the applicant must make an additional showing that the biosimilar can be expected to produce the 
same clinical result as the reference product in any given patient, and if the product is administered more than once to a 
patient, that risks in terms of safety or diminished efficacy of alternating or switching between the biological product and 
the reference product is no greater than the risk of using the reference product without switching. Although FDA has 
provided guidance on what information and data an applicant should submit to enable an interchangeability 
determination, thus far FDA has not licensed any biologic as being interchangeable with its reference product. 

The PHSA also provides a period of exclusivity for pioneer biologics.  Specifically, FDA may not accept a 

biosimilar application referencing data from a pioneer biologic (i.e., one approved through a full BLA) until four years 
have elapsed from the date of first licensure of the pioneer biologic.  FDA may not approve a biosimilar application 

23 

referencing data from a pioneer biologic until 12 years have elapsed since the date of first licensure of the pioneer 
biologic.  There are certain restrictions and limitations on the types of BLAs that are eligible for biologics exclusivity as 
well as what constitutes the date of first licensure for a pioneer biologic. 

In the EU, a pathway for the approval of biosimilars has existed since 2005. 

Healthcare compliance laws. In the U.S., commercialization of OMIDRIA and our product candidates, if approved, 

is subject to regulation and enforcement under a number of federal and state healthcare compliance laws administered 
and enforced by various agencies. These include, but are not limited to, the following: 

• 

• 

• 

• 

the federal Anti-Kickback Statute, which prohibits offering or paying anything of value to a person or entity to 
induce or reward referrals for goods or services reimbursed by a federal healthcare program such as Medicare 
or Medicaid; 

the federal False Claims Act, which prohibits presenting or causing to be presented a false claim for payment by 
a federal healthcare program, and which has been interpreted to also include claims caused by improper drug-
manufacturer product promotion or the payment of kickbacks; 

a variety of governmental pricing, price reporting, and rebate requirements, including those under Medicaid and 
the Veterans Health Care Act; and 

the so-called Sunshine Act and certain provisions of the Affordable Care Act, which require that we report to 
the federal government information on certain financial payments and other transfers of value made to certain 
health care providers and institutions, as well as certain information regarding our distribution of drug samples. 

In addition to these federal law requirements, several U.S. states have enacted similar laws requiring periodic 
reporting and/or disclosure related to our marketing, sales and other activities, or regulating certain sales and marketing 
activities, such as provision of meals, gifts or entertainment to certain health care providers. We may also be subject to 
federal or state privacy laws if we receive protected patient health information. 

Similar requirements apply to our operations outside of the U.S. Laws in the U.S. such as the Foreign Corrupt 
Practices Act prohibit the offering or payment of bribes or inducements to foreign public officials for business, including 
physicians or other medical professionals who are employees of public healthcare entities. In addition, many non-U.S. 
jurisdictions in which we operate, or may operate in the future, have their own laws similar to the healthcare compliance 
laws that exist in the U.S. 

Pharmaceutical Pricing and Reimbursement 

Overview. In both U.S. and foreign markets, our ability to commercialize our products and product candidates 
successfully, and to attract commercialization partners for our products and product candidates, depends in significant 
part on the availability of adequate financial coverage and reimbursement from third-party payers including, in the U.S., 
managed care organizations and other private health insurers as well as governmental payers such as the Medicare and 
Medicaid programs. Reimbursement by a third-party payer may depend on a number of factors, including the payer’s 
determination that use of a product is: 

• 

• 

• 

• 

a covered benefit under its health plan; 

safe, effective and medically necessary; 

appropriate for the specific patient; 

cost-effective; and 

24 

• 

neither experimental nor investigational. 

Reimbursement by government payers is based on statutory authorizations and complex regulations that may change 

with annual or more frequent rulemaking, as well as legislative reform measures. 

Third-party private and governmental payers are increasingly challenging the prices charged for medicines and 

examining their cost-effectiveness in addition to their safety and efficacy. We may need to conduct expensive 
pharmacoeconomic studies in order to demonstrate the cost effectiveness of our products or product candidates. Even 
with the availability of such studies, third-party private and/or governmental payers may not provide coverage and 
reimbursement for our products or product candidates, in whole or in part. 

United States. Political, economic and regulatory influences are subjecting the healthcare industry in the U.S. to 
fundamental changes. There have been, and we expect there will continue to be, legislative and regulatory proposals to 
change the healthcare system in ways that could significantly affect our business. For example, the 2010 Affordable Care 
Act (the “ACA”), is intended to broaden access to health insurance, reduce or constrain the growth of healthcare 
spending, enhance remedies against fraud and abuse, add transparency requirements for the healthcare and health 
insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. 
Other legislative changes included a two percent across-the-board reduction to Medicare payments to providers, 
effective April 1, 2013, which, due to subsequent legislative amendments, will stay in effect through fiscal year 2029 
unless additional congressional action is taken. (A temporary suspension of this reduction during the public health 
emergency for the pandemic is currently scheduled to expire on March 31, 2021.) The American Taxpayer Relief Act of 
2012, among other things, reduced Medicare payments to several providers, and increased the period for the government 
to recover overpayments to providers from three to five years. In December 2017, portions of the ACA dealing with the 
individual mandate insurance requirement were effectively repealed by the Tax Cuts and Jobs Act of 2017. In 
December 2018, a federal district court judge in Texas found the ACA’s individual mandate to be unconstitutional and, 
therefore, the entire law to be invalid. In December 2019, the Fifth Circuit affirmed the ruling regarding the individual 
mandate but remanded the case to the district court for additional analysis of the question of severability and whether 
portions of the law remain valid. The case is currently pending at the Supreme Court, and a decision is expected by 
mid-2021.  

In November 2020, CMS issued an interim final rule through the CMS Innovation Center whereby Medicare Part B 

reimbursement for “certain high-cost prescriptions drugs” would be no more than most-favored-nation price (i.e., the 
lowest price) after adjustments, for a pharmaceutical product that the drug manufacturer sells in a member country of the 
Organization for Economic Cooperation and Development that has a comparable per-capita gross domestic product. In 
December 2020, the United States District Court in Northern California issued a nationwide preliminary injunction 
against implementation of the interim final rule. The incoming Biden administration has indicated that lowering 
prescription drug prices is a priority, but it is not yet clear what steps the administration will take or whether such steps 
will be successful. We cannot predict the ultimate content, timing or effect of any healthcare reform legislation or 
executive order or the impact that the resulting changes may have on us. 

We are unable to predict what additional legislation, regulations, policies or court orders, if any, relating to the 

healthcare industry or coverage and reimbursement may be enacted or imposed in the future or what effect such 
legislation, regulations, policies or court orders would have on our business. Any cost-containment measures, including 
those listed above, or other healthcare system reforms that are adopted could have a material adverse effect on our 
business prospects and financial operations. 

Europe. Governments in the various member states of the EU influence or control the price of medicinal products in 
their countries through their pricing and reimbursement rules and control of national healthcare systems that fund a large 
part of the cost of those products to consumers. To obtain reimbursement or pricing approval, some of these countries 
may require the completion of clinical trials or pharmacoeconomic studies that assess the cost-effectiveness of a product 
or product candidate relative to currently available therapies or relative to a specified standard. The downward pressure 
on healthcare costs in general, and prescription medicines in particular, has become very intense and is creating 
increasingly high barriers to the entry of new products in these markets.

Research and Development 

We have built a research and development organization that includes expertise in discovery research, preclinical 

development, product formulation, analytical and medicinal chemistry, manufacturing, clinical development and 
regulatory and quality assurance. We operate cross-functionally and are led by an experienced management team. We 
use rigorous project management techniques to make disciplined strategic decisions regarding our research and 
development programs and to limit the risk profile of our product pipeline. We also access relevant market information 
and key opinion leaders in creating target product profiles and, when appropriate, as we advance our programs to 
commercialization. We engage third parties on a limited basis to conduct portions of our preclinical research; however, 
we are not substantially dependent on any third parties for our preclinical research nor do any of these third parties 
conduct a major portion of our preclinical research. We also engage multiple clinical sites to conduct our clinical trials. 
None of these sites conduct the major portion of our clinical trials and we are not substantially dependent on any one of 
them. 

Employees 

As of December 31, 2020, we had 277 full-time employees, 145 of whom are in research and development, 81 of 
whom are in sales and marketing and 51 of whom are in finance, legal, business development and administration. Our 
full-time employees include eight with M.D.s and 38 with Ph.Ds., of whom one and 22, respectively, are in research and 
development. None of our employees is represented by a labor union, and we consider our employee relations to be 
good.

SUMMARY RISK FACTORS 

The risk factors described below are a summary of the principal risk factors associated with an investment in our 
company. These are not the only risks we face. You should carefully consider the risk factors discussed in this summary, 
as well as the risk factors described in Item 1A. of this Annual Report on Form 10-K. 

Risks related to our products, programs and operations include, but are not limited to, the following:  

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

the commercial success of OMIDRIA and whether we will continue to maintain separate payment for 
OMIDRIA; 

the impact of the COVID-19 pandemic on our business, operations and financial results as well as significant 
uncertainty around the evaluation of narsoplimab as a potential treatment for critically ill COVID-19 patients;

the impact of anti-takeover provisions in our charter documents and under Washington law on potential 
acquisitions of our company. 

ITEM 1A.            RISK FACTORS 

The risks and uncertainties described below may have a material adverse effect on our business, prospects, 
financial condition or operating results. In addition, we may be adversely affected by risks that we currently deem 
immaterial or by other risks that are not currently known to us. You should carefully consider these risks before making 
an investment decision. The trading price of our common stock could decline due to any of these risks and you may lose 
all or part of your investment. In assessing the risks described below, you should also refer to the other information 
contained in this Annual Report on Form 10-K. 

Risks Related to Our Products, Programs and Operations 

Our ability to achieve profitability is highly dependent on the commercial success of OMIDRIA, and to the extent 
OMIDRIA is not successful, our business, financial condition and results of operations may be materially 
adversely affected and the price of our common stock may decline. 

OMIDRIA is currently our only product that has been approved by FDA for commercial sale in the U.S. For the 
three and 12 months ended December 31, 2020, we recorded net sales of OMIDRIA of $10.6 million and $73.8 million, 
respectively. Revenues from sales of OMIDRIA have not been sufficient to fund our operations fully in prior periods and 
we cannot provide assurance that revenues from OMIDRIA sales will be sufficient to fund our operations fully in the 
future. We will need to generate substantially more product revenue from OMIDRIA or generate other revenue such as 
through sales of future approved products to achieve and sustain profitability. We may be unable to sustain or increase 
revenues generated from OMIDRIA product sales for a number of reasons, including: 

• 

reduced volume of ophthalmic surgical procedures and corresponding reduction in demand for OMIDRIA as a 
result of the COVID-19 pandemic; 

•  whether CMS will maintain its current payment policies, which can be revised through annual rulemaking and 

associated comment periods, and continue to pay separately under Medicare Part B for non-opioid pain 
management drugs like OMIDRIA when used during surgery in the ASC setting; 

• 

pricing, coverage and reimbursement policies of government and private payers such as Medicare, Medicaid, 
the U.S. Department of Veterans Affairs, group purchasing organizations, insurance companies, health 
maintenance organizations and other plan administrators; 

30 

• 

• 

• 

• 

• 

• 

a lack of acceptance by physicians, patients and other members of the healthcare community; 

interruptions in supply of OMIDRIA from our contract manufacturing partners; 

the availability, relative price and efficacy of the product as compared to alternative treatment options or 
branded, compounded or generic competing products; 

an unknown safety risk; 

the failure to enter into and maintain acceptable partnering arrangements for marketing and distribution of 
OMIDRIA outside of the U.S.; and 

changed or increased regulatory restrictions in the U.S., EU and/or other foreign territories. 

Clinical trials evaluating narsoplimab for treatment of COVID-19 may be unsuccessful and, even if successful, we 
may be unable to manufacture narsoplimab in quantities adequate to meet demand. 

Narsoplimab has been used to treat approximately 20 critically ill COVID-19 patients under our compassionate use 

program with highly positive results. However, we cannot provide assurance that the results observed in the 
compassionate use program will be observed in any future study of narsoplimab for this indication, including the I-SPY 
COVID-19 trial, or that we will receive regulatory authorization or approval for narsoplimab in the treatment of 
COVID-19 patients.  

Narsoplimab or any other therapeutic candidate that we may develop to treat COVID-19 will be subject to risks in 
addition to those normally associated with pharmaceutical research, development, and commercialization, such as higher 
risk of technical failure, lower and transient opportunities for revenue, higher manufacturing costs, product safety or 
efficacy risks related to an expedited research and development timeline, and novel liability theories. FDA or other 
regulatory bodies may require that we conduct a large-scale trial of narsoplimab in COVID-19 patients, in addition to the 
I-SPY COVID-19 trial to grant any approval or authorization. These risks may affect our ability to develop or 
commercialize a therapeutic for COVID-19 or any other current or future indication. 

Additionally, contract manufacturing capacity and supplies of raw materials necessary for the production of 

narsoplimab are limited and we may be unable to secure the large-scale manufacturing capacity from third parties 
necessary to manufacture narsoplimab in sufficient quantities to enable broader availability of narsoplimab for 
COVID-19 patients. In addition, widespread vaccination and/or the availability of alternative therapies for COVID-19 
could lead to the diversion of governmental and other potential sources of funding or other manufacturing assistance 
away from us and toward COVID-19 vaccines or other therapeutics and/or limit the commercial viability of narsoplimab 
for the treatment of COVID-19. 

The spread of COVID-19 and efforts to reduce its transmission may negatively impact our business, operations 
and financial results. 

The COVID-19 pandemic has significantly affected the global economy and has adversely affected our sales of 
OMIDRIA due to a reduction in the overall volume of cataract surgery and intraocular lens replacement procedures. 
Although cataract surgeries have resumed to varying degrees in locations throughout the country, if the number of 
cataract procedures once again becomes meaningfully limited, either by necessity for time-consuming safety protocols, 
reduction in patient demand, or the imposition of prohibitions on elective surgeries in some localities, then we would 
expect there to be a corresponding reduction in demand for OMIDRIA. 

We may also experience disruptions to our operations due to COVID-19, such as delays or disruptions with respect 

to manufacturing of clinical or commercial drug substance or drug product and delays in our clinical trials or in the 
submission or review of regulatory applications. Such delays or disruptions could negatively affect our commercial 
operations, clinical programs, and research and development. The health of our employees, contractors and other persons 

31 

on whom we rely may be adversely affected by COVID-19. Although we are taking precautionary measures intended to 
help minimize the risk of the virus to our employees, these measures may be ineffective or may otherwise adversely 
affect our productivity. In addition, the conditions created by the pandemic may intensify other risks inherent in our 
business. Due to the unknown magnitude, duration and outcome of the COVID-19 pandemic, it is not possible to 
estimate precisely its impact on our business, operations or financial results; however, the impact could be material.  

To the extent COVID-19 adversely affects our business, financial condition, and results of operations and global 
economic conditions more generally, it may also have the effect of heightening many of the other risk factors set forth 
herein.. 

If OMIDRIA or any other product that we develop and commercialize does not receive adequate coverage or 
reimbursement from governments and/or private payers, or if we do not establish and maintain market-
acceptable pricing for OMIDRIA or those potential other commercialized products, our prospects for revenue 
and profitability would suffer. 

Our revenues depend heavily on the pricing, availability and duration of adequate coverage or reimbursement for 

the use of products that we or our third-party business partners commercialize, including OMIDRIA, from government, 
private and other third-party payers, both in the U.S. and in other countries.  

Pass-through reimbursement, which allows for separate payment (i.e., outside the packaged payment rate for the 

surgical procedure) under Medicare Part B, expired for OMIDRIA on October 1, 2020. In December 2020, CMS 
confirmed that OMIDRIA qualifies for separate payment when used on Medicare Part B patients in the ASC setting 
under CMS’ policy for non-opioid pain management surgical drugs. CMS made separate payment for OMIDRIA 
effective retroactively as of October 1, 2020. CMS’ current non-opioid separate payment policy and, as a result, separate 
payment for OMIDRIA thereunder, like other CMS policies in the OPPS and ASC systems, can be changed by CMS 
through its OPPS/ASC annual rulemaking and comment process. We believe that CMS will continue its separate 
payment policy for non-opioid pain management surgical drugs, which has been in effect since 2019, and that 
OMIDRIA will continue to be separately reimbursed when used in the ASC setting. However, we can provide no 
guarantee that CMS will continue its separate payment policy in future years. If the future reimbursement status of 
OMIDRIA continues to be uncertain, then demand for OMIDRIA from ASCs and hospitals may be reduced 
substantially. In such event, sales to our wholesalers may decrease correspondingly, as they adjust on-hand inventory in 
anticipation of reduced demand from end users. 

There may be significant delays in obtaining coverage or reimbursement for newly approved products, and we may 
not be able to provide data sufficient to be granted adequate coverage or reimbursement. Even when a payer determines 
that a product is eligible for reimbursement, coverage may be limited to the uses of a product that are either approved by 
FDA (or, in other countries, the relevant country’s regulatory agency) and/or appear in a recognized drug compendium, 
or other conditions may apply. Moreover, eligibility for coverage does not mean that any product will be reimbursed at a 
rate that allows us to make a profit in all cases or at a rate that covers our costs, including research, development, 
manufacturing, sales and distribution. Increasingly, government and private third-party payers that reimburse for 
healthcare services and products are requiring that companies provide them with predetermined discounts from list 
prices and are challenging the prices charged for medical products, which could adversely impact the pricing of our 
products. Any reduction in reimbursement from Medicare or other government programs may result in a similar 
reduction in payments from private payers. Pricing may also be adversely affected by changes in the terms, scope and/or 
complexity of government pricing requirements. Even if we achieve coverage or reimbursement for a product, the initial 
rate or method at which the product will be reimbursed could become unfavorable to us at the time reimbursement is 
initiated or in the future or may be of a limited duration. In addition, obtaining acceptable coverage and reimbursement 
from one payer does not guarantee that we will obtain similar acceptable coverage or reimbursement from another payer. 

In non-U.S. jurisdictions, we must obtain separate reimbursement approvals and comply with related foreign legal 
and regulatory requirements. In some countries, including those in the EU, our products may be subject to government 
price controls. Pricing negotiations with governmental authorities can take a considerable amount of time and 
expenditure of resources after the receipt of marketing approval for a product. We provide no assurances that the price of 
any product in one or more of these countries or regions will allow us to make a profit or cover our costs, including 

32 

research, development, manufacturing, sales and distribution, and as a result we may decide to delay, potentially 
indefinitely, initiating sales in the particular country or region. 

If the reimbursement or pricing that we are able to obtain and maintain for any product that we develop and 

commercialize, including OMIDRIA, is inadequate, is significantly delayed or is subject to overly restrictive conditions, 
our ability to generate revenue, attain profitability and/or commercialize our product candidates may be impaired and 
there could be a material adverse effect on our business, financial condition, results of operations and growth prospects 
and trading price of our stock could decline. 

Failure to obtain and maintain regulatory approval in the U.S. or in foreign jurisdictions would prevent us from 
marketing our current and future products. 

Our BLA for narsoplimab for the treatment of HSCT-TMA is under priority review by FDA. The regulatory process 

is subject to substantial agency discretion and risks, including those described herein and elsewhere in these “Risk 
Factors.” FDA may require additional data regarding narsoplimab or HSCT-TMA for any reason, which could delay or 
require a resubmission our BLA, or FDA may approve narsoplimab for a much narrower indication or patient population 
than we have requested and/or with significant restrictions on distribution or use, including through a REMS. Ultimately, 
we cannot guarantee that FDA will ever approve narsoplimab for the treatment of HSCT-TMA or any other indication. 

We also intend to have OMIDRIA and our current and future product candidates, if approved, marketed outside the 

U.S. In order to market our products in non-U.S. jurisdictions, we or our partners must obtain separate regulatory 
approvals and comply with numerous and varying regulatory requirements. The regulatory approval procedure varies 
among countries and can involve additional testing and data review. The requirements governing marketing 
authorization, the conduct of clinical trials, pricing and reimbursement vary from country to country. Approval by FDA 
does not ensure approval by the EMA, and approval by one foreign regulatory authority does not ensure approval by 
regulatory agencies in other foreign countries or by FDA. The time required to obtain regulatory approval outside the 
U.S. and EU may differ from that required to obtain FDA or EU approval. The foreign regulatory approval process may 
include all of the risks associated with obtaining FDA approval discussed in these “Risk Factors” and we may not obtain 
foreign regulatory approvals on a timely basis, or at all. In addition, even if we were able to obtain regulatory approval 
for a product in one or more foreign jurisdictions, we may need to complete additional requirements to maintain that 
approval and our ability to market the product in the applicable jurisdiction. 

Our operating results are unpredictable and may fluctuate. 

Our operating results are difficult to predict and will likely fluctuate from quarter to quarter and year to year. We 

believe that our quarterly and annual results of operations may be affected by a variety of factors, including: 

• 

• 

• 

• 

• 

the level and timing of commercial sales of OMIDRIA, as well as our product candidates if and when approved 
or commercialized; 

the extent of coverage and reimbursement for OMIDRIA; 

the amount of OMIDRIA chargebacks, rebates and product returns; 

the extent of any payments received from collaboration arrangements and development funding as well as the 
achievement of development and clinical milestones under collaboration and license agreements that we may 
enter into from time to time and that may vary significantly from quarter to quarter; and 

the timing, cost and level of investment in our research and development activities as well as expenditures we 
will or may incur to acquire or develop additional technologies, products and product candidates, or in 
preparation for potential commercialization of our product candidates. 

33 

In addition, the number of procedures or cases in which OMIDRIA or any of our product candidates, if 

commercialized, would be used may be significantly less than the total number of such procedures performed or total 
possible market size. These and other factors, including multiple changes in the reimbursement status for OMIDRIA 
since initially approved, make it difficult for us to forecast and provide accurate guidance (including updates to prior 
guidance) related to our expected financial performance. If our operating results are below the expectations of securities 
analysts or investors, the trading price of our stock could decline. 

We have incurred cumulative operating losses since inception. If we are unable to raise additional capital when 
needed, our commercial operations may be limited and we may be unable to complete the development and 
commercialization of our product candidates or to continue our other preclinical development programs. 

Our operations have consumed substantial amounts of cash since our incorporation and, as of December 31, 2020, 
we had an accumulated deficit of approximately $872.7 million. We expect to continue to spend substantial amounts to: 

• 

• 

• 

initiate and conduct clinical trials and manufacture clinical and registration batches for our programs and 
product candidates; 

continue OMIDRIA sales and marketing; 

continue research and development in our programs; 

•  make principal, interest and fee payments as required under our 6.25% Convertible Senior Notes due 2023 (the 
“2023 Notes”) and 5.25% Convertible Senior Notes due 2026 (the “2026 Notes” and together with the 2023 
Notes, the “Convertible Notes”); and 

• 

commercialize and launch product candidates for which we may receive regulatory approval. 

We expect to continue to incur additional losses until such time as we generate significant revenue from the sale of 

OMIDRIA, other commercial products or partnerships. We are unable to predict the extent of any future losses and 
cannot provide assurance that we will generate sufficient revenue from OMIDRIA or other commercial products in the 
future to fund our operations fully. If we are unable to generate sufficient revenue from the sale of OMIDRIA, other 
commercialized products or partnership arrangements, we may never become and remain profitable and will be required 
to raise additional capital to continue to fund our operations. We cannot be certain that additional capital will be 
available to us on acceptable terms, if at all, when required. Adverse developments to our financial condition or 
business, as well as disruptions in the global equity and credit markets, may limit our ability to access capital. If we do 
not raise additional capital when needed through one or more funding avenues, such as debt or equity financings or 
corporate partnering, we may have to significantly delay, scale back or discontinue the development or 
commercialization of one or more of our product candidates or one or more of our preclinical programs or other research 
and development initiatives. In addition, we may be required to seek collaborators for one or more of our current or 
future products at an earlier stage than otherwise would be desirable or on terms that are less favorable than otherwise 
might be available or to relinquish or license on unfavorable terms our rights to technologies or products that we 
otherwise would seek to develop or commercialize ourselves. We also may have insufficient funds or otherwise be 
unable to advance our preclinical programs, such as potential new drug targets developed from our GPCR program, to a 
point where they can generate revenue through partnerships, collaborations or other arrangements. Any of these actions 
could limit the amount of revenue we are able to generate and harm our business and prospects. 

We are subject to extensive government regulation and the failure to comply with these regulations may have a 
material adverse effect on our operations and business. 

Both before and after approval of any product, we and our suppliers, contract manufacturers and clinical 

investigators are subject to extensive regulation by governmental authorities in the U.S. and other countries, covering, 
among other things, testing, manufacturing, quality control, clinical trials, post-marketing studies, reporting, risk 
management plans, labeling, advertising, promotion, distribution, import and export, governmental pricing, price 
reporting and rebate requirements. Failure to comply with applicable requirements could result in one or more of the 

34 

following actions: warning letters; unanticipated expenditures; delays in approval or refusal to approve a product 
candidate; product recall or seizure; interruption of manufacturing or clinical trials; operating or marketing restrictions; 
injunctions; criminal prosecution and civil or criminal penalties including fines and other monetary penalties; adverse 
publicity; and disruptions to our business. Further, government investigations into potential violations of these laws 
would require us to expend considerable resources and face adverse publicity and the potential disruption of our business 
even if we are ultimately found not to have committed a violation. 

Obtaining FDA approval of our product candidates requires substantial time, effort and financial resources and may 

be subject to both expected and unforeseen delays, and there can be no assurance that any approval will be granted on 
any of our product candidates on a timely basis, if at all. Even if we discuss with, and obtain feedback from, FDA 
regarding our proposed clinical trials, clinical data collection protocols and nonclinical studies before initiating those 
trials or studies, FDA may decide that the design of our clinical trials or clinical data collection protocols as actually run, 
or our resulting data, are insufficient for approval of our product candidates and may require us to run additional 
preclinical, clinical or other studies or perform additional work related to chemistry, manufacturing and controls. In 
addition, we, FDA or an independent institutional review board or ethics committee may suspend or terminate human 
clinical trials at any time on various grounds, including a finding that the patients are or would be exposed to an 
unacceptable health risk or because of the way in which the investigators on whom we rely carry out the trials. We are 
subject to extensive government regulation of the testing of our investigational products, including the requirement that 
we conduct all of our clinical trials in accordance with FDA’s GCP requirements and similar requirements outside of the 
United States. If we are unable to comply with these requirements, if we are required to conduct additional trials or to 
conduct other testing of our product candidates beyond that which we currently contemplate for regulatory approval, if 
we are unable to complete our clinical trials or other testing successfully, or if the results of these and other trials or tests 
fail to demonstrate efficacy or raise safety concerns, we may face substantial additional expenses, be delayed in 
obtaining marketing approval for our product candidates or may never obtain marketing approval. 

We are also required to comply with extensive governmental regulatory requirements after a product has received 

marketing authorization. Governing regulatory authorities may require post-marketing studies that may negatively 
impact the commercial viability of a product. Once on the market, a product may become associated with previously 
undetected adverse effects and/or may develop manufacturing difficulties. We are required to comply with other post-
marketing requirements including current Good Manufacturing Practices, advertising and promotion restrictions, 
pharmacovigilance requirements including risk management activities, reporting and recordkeeping obligations, and 
other requirements. As a result of any of these or other problems or failure to comply with our regulatory obligations, a 
product’s regulatory approval could be withdrawn, which could harm our business and operating results. In addition, we 
must maintain an effective healthcare compliance program in order to comply with U.S. and other laws applicable to 
marketed drug products and, in particular, laws (such as the Anti-Kickback Statute, the False Claims Act and the 
Sunshine Act) applicable when drug products are purchased or reimbursed by a federal or state healthcare program. U.S. 
laws such as the Foreign Corrupt Practices Act prohibit the offering or payment of bribes or inducements to foreign 
public officials, including potentially physicians or other medical professionals who are employees of public healthcare 
entities in jurisdictions outside the U.S. In addition, many countries have their own laws similar to the healthcare 
compliance laws that exist in the U.S. Implementing and maintaining an effective compliance program requires the 
expenditure of significant time and resources. If we are found to be in violation of any of these laws, we may be subject 
to significant penalties, including but not limited to civil or criminal penalties, damages and fines as well as exclusion 
from government healthcare programs. 

We may face difficulties from changes to current regulations as well as future legislation. 

Existing regulatory policies may change and additional government regulations may be enacted that could prevent, 

limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of 
government regulation that may arise from future legislation or administrative action, either in the U.S. or abroad. If we 
are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we 
are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we 
may not achieve or sustain profitability. 

35 

There is uncertainty with respect to the impact that healthcare reform legislation and the policies of the Biden 
administration may have on coverage and reimbursement for healthcare items and services covered by plans that are 
authorized by the ACA. We expect that the ACA, if it remains in effect, as well as other healthcare reform measures that 
may be adopted in the future, may result in more rigorous coverage criteria and apply downward pressure on the price 
that we receive for any approved product. Any reduction in reimbursement from Medicare or other government 
programs may result in a similar reduction in payments from private payers. If the ACA were to be invalidated by the 
Supreme Court or repealed, any resulting reduction in the percentage of the U.S. population that has healthcare insurance 
could reduce the market for our products. The implementation of cost containment measures or other healthcare reforms 
may prevent us from being able to generate sufficient revenue, attain and/or maintain profitability or commercialize our 
product candidates. We cannot be sure whether additional legislative changes will be enacted, or whether FDA 
regulations, guidance or interpretations will be changed, or what the impact of such changes on OMIDRIA or the 
marketing approvals of our product candidates, if any, may be. 

 We have no internal capacity to manufacture commercial or clinical supplies of OMIDRIA or our product 
candidates and intend to continue to rely solely on third-party manufacturers. If the contract manufacturers that 
we rely on experience difficulties manufacturing and supplying OMIDRIA or our product candidates, or fail 
FDA or other regulatory inspections, our clinical trials, regulatory submissions and ability to sell OMIDRIA or 
any other commercialized product and generate revenue may be significantly limited or delayed. 

We rely and intend to continue to rely on third-party manufacturers to produce commercial quantities of OMIDRIA 

and clinical drug supplies of our product candidates that are needed for clinical trials and to support NDAs, BLAs, or 
similar applications to regulatory authorities seeking marketing approval for our product candidates, as well as to 
produce inventory of our product candidates for commercial use in anticipation of marketing approval. We cannot 
provide any assurance that we will be able to enter into or maintain these types of arrangements on commercially 
reasonable terms, or at all. If we or one of our manufacturers were to terminate one of these arrangements early, or the 
manufacturer was unable to supply product quantities sufficient to meet our requirements, we would be required to 
transfer manufacturing to an approved alternative facility and/or establish additional manufacturing and supply 
arrangements. We may also need to establish additional or replacement manufacturers, potentially with little or no 
notice, in the event that one of our manufacturers fails to comply with FDA and/or other pharmaceutical manufacturing 
regulatory requirements. Even if we are able to establish additional or replacement manufacturers, identifying these 
sources and entering into definitive supply agreements and obtaining regulatory approvals may require a substantial 
amount of time and cost and may create a shortage of the product. It can take several years to qualify and validate a new 
contract manufacturer, and we cannot guarantee that we would be able to complete in a successful and timely manner the 
appropriate validation processes or obtain the necessary regulatory approvals for one or more additional or replacement 
manufacturers. Such alternate supply arrangements may not be available on commercially reasonable terms, or at all. 
Additionally, if we are unable to engage multiple suppliers to manufacture our products, we may have inadequate supply 
to meet demand for our product. 

In addition, narsoplimab is a biologic drug product and any other product candidate from certain of our programs, 

including but not limited to MASP-2 and MASP-3, could be a biologic drug product. We do not have the internal 
capability to produce biologics for use in clinical trials or on a commercial scale. There are only a limited number of 
manufacturers of biologic drug products and we may be unable to enter into agreements on commercially reasonable 
terms with a sufficient number of them to meet clinical or commercial demand, if at all. The regulatory requirements for 
commercial supply are more stringent than for clinical supply and we cannot guarantee that a contract manufacturer 
producing drug product for clinical trials will be able to complete successfully the appropriate validation processes or 
obtain the necessary regulatory approvals for marketing approval and commercial supply in a timely manner or at all. 

Our contract manufacturers may encounter difficulties with formulation, manufacturing, supply chain and/or release 

processes that could result in delays in clinical trials and/or regulatory submissions or that could impact adversely the 
commercialization of our products or product candidates, as well as in the initiation of enforcement actions by FDA and 
other regulatory authorities. For example, our manufacturers are required to comply with FDA’s GMP requirements and 
are subject to periodic inspections by FDA.  If our manufacturers are unable to comply with FDA requirements, they 
may be unable to meet our supply needs. These difficulties also could result in the recall or withdrawal of a product from 
the market or a failure to have adequate supplies to meet market demand. If the safety or manufacturing quality of 

36 

OMIDRIA or any product candidate supplied by contract manufacturers is compromised due to one or more of those 
contract manufacturers’ failure to adhere to applicable laws or for other reasons, we may not be able to maintain 
regulatory approval of OMIDRIA, to continue sales and marketing of OMIDRIA, to run clinical trials or to obtain and 
maintain regulatory approval for one or more of our product candidates, which would harm our business and prospects 
significantly. 

Any significant delays in the manufacture and/or supply of clinical or commercial supplies could materially harm 

our business, financial condition, results of operations and prospects. 

Ingredients, excipients, test kits and other materials necessary to manufacture OMIDRIA or our product 
candidates may not be available on commercially reasonable terms, or at all, which may adversely affect the sales 
of OMIDRIA or development and commercialization of our product candidates. 

We and our third-party manufacturers must obtain from third-party suppliers the APIs, excipients, and/or other raw 

materials plus primary and secondary packaging materials necessary for our contract manufacturers to produce 
OMIDRIA and our product candidates for our clinical trials and, to the extent approved or commercialized, for 
commercial distribution. Although we have entered or intend to enter into agreements with third-party suppliers that will 
guarantee the availability and timely delivery of APIs, excipients, test kits and materials for OMIDRIA and our product 
candidates, we have not yet entered into agreements for the supply of all such ingredients, excipients, test kits or 
materials, and we may be unable to secure all such supply agreements or guarantees on commercially reasonable terms, 
if at all. Even if we were able to secure such agreements or guarantees, our suppliers may be unable or choose not to 
provide us the ingredients, excipients, test kits or materials in a timely manner or in the quantities required. If we or our 
third-party manufacturers are unable to obtain the quantities of these ingredients, excipients or materials that are 
necessary for the manufacture of commercial supplies of OMIDRIA, our ability to generate revenue from the sale of 
OMIDRIA would be materially and adversely affected. Further, if we or our third-party manufacturers are unable to 
obtain APIs, excipients, test kits and materials as necessary for our clinical trials or for the manufacture of commercial 
supplies of our product candidates, if approved, potential regulatory approval or commercialization would be delayed, 
which would materially and adversely affect our ability to generate revenue from the sale of our product candidates. 

If our clinical trials or clinical protocols are delayed, suspended or terminated, we may be unable to develop our 
product candidates on a timely basis, which would adversely affect our ability to obtain regulatory approvals, 
increase our development costs and delay or prevent commercialization of approved products. 

We cannot predict whether we will encounter problems with any of our completed, ongoing or planned clinical trials 
or clinical data collection protocols that will cause regulatory agencies, institutional review boards or ethics committees, 
or us to delay our clinical trials or suspend or delay the analysis of the data from those trials. Clinical trials and clinical 
data protocols can be delayed for a variety of reasons, including: 

• 

• 

• 

discussions with FDA, the EMA or other foreign authorities regarding the scope or design of our clinical trials 
or clinical data collection protocols; 

delays or the inability to obtain required approvals from institutional review boards, ethics committees or other 
responsible entities at clinical sites selected for participation in our clinical trials; 

delays in enrolling patients into clinical trials, collecting data from enrolled patients or collecting historical 
control data for any reason including disease severity, trial or data collection protocol design, study eligibility 
criteria, patient population size (e.g., for orphan diseases or for some pediatric indications), proximity and/or 
availability of clinical trial sites for prospective patients, availability of competing therapies and clinical trials, 
regional differences in diagnosis and treatment, perceived risks and benefits of the product or product 
candidate, disruptions due to external events, including an outbreak of pandemic or contagious disease such as 
the COVID-19 coronavirus, which has slowed enrollment in our clinical trials of narsoplimab in patients with 
IgA nephropathy; 

• 

lower than anticipated retention rates of patients in clinical trials; 

37 

• 

• 

• 

• 

• 

• 

• 

• 

the need to repeat or conduct additional clinical trials as a result of inconclusive or negative results, failure to 
replicate positive early clinical data in subsequent clinical trials, failure to deliver an efficacious dose of a 
product candidate, poorly executed testing, a failure of a clinical site to adhere to the clinical protocol or to 
follow GCPs or other study requirements, an unacceptable study design or other problems; 

adverse findings in clinical or nonclinical studies related to the safety of our product candidates in humans; 

an insufficient supply of product candidate materials or other materials necessary to conduct our clinical trials; 

the need to qualify new suppliers of product candidate materials for FDA and foreign regulatory approval; 

an unfavorable inspection or review by FDA or other regulatory authority of a clinical trial site or records of 
any clinical investigation; 

the occurrence of unacceptable drug-related side effects or adverse events experienced by participants in our 
clinical trials; 

the suspension by a regulatory agency of a trial by imposing a clinical hold; or 

the amendment of clinical trial or data collection protocols to reflect changes in regulatory requirements and 
guidance or other reasons as well as subsequent re-examination of amendments to clinical trial or data 
collection protocols by regulatory agencies, institutional review boards or ethics committees. 

In addition, our clinical trial or development programs have been, and in the future may be, suspended or terminated 

by us, FDA or other regulatory authorities, or institutional review boards or ethics committees due to a number of 
factors, including: 

• 

• 

• 

• 

• 

• 

• 

failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols; 

inspection of the clinical trial operations or trial sites by FDA or other regulatory authorities resulting in the 
imposition of a clinical hold; 

our failure to comply with our regulatory obligations as a sponsor of clinical research, such as adverse event 
reporting, control of study drug, adequate study monitoring, and other obligations; 

the failure to remove a clinical hold in a timely manner, if at all; 

unforeseen safety issues or any determination that a trial presents unacceptable health risks; 

inability to deliver an efficacious dose of a product candidate; or 

lack of adequate funding to continue the clinical trial or development program, including as a result of 
unforeseen costs due to enrollment delays, requirements to conduct additional trials and studies and/or 
increased expenses associated with the services of our contract research organizations (“CROs”), or other third 
parties. 

If the results of our clinical trials are not available when we expect or if we encounter any delay in the analysis of 

data from our clinical trials, we may be unable to file for regulatory approval or conduct additional clinical trials on the 
schedule we currently anticipate. Many of the factors that cause, or lead to, a delay in the commencement or completion 
of clinical trials may also ultimately lead to the denial of regulatory approval of a product candidate. Any delays in 
completing our clinical trials could increase our development costs, could slow down our product development and 
regulatory submission process, could delay our receipt of product revenue and could make it difficult to raise additional 

38 

capital. In addition, significant clinical trial delays also could allow our competitors to bring products to market before 
we do and impair our ability to commercialize our future products, potentially harming our business. 

Because we have a number of product candidates and development programs, we may expend our limited 
resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or 
indications for which there is a greater likelihood of obtaining regulatory approval and that may be more 
profitable, if approved. 

We have limited resources and must focus on the product candidates and clinical and preclinical development 
programs that we believe are the most promising. As a result, we may forgo or delay the pursuit of opportunities with 
other product candidates or other indications that later prove to have greater commercial potential and may not be able to 
progress development programs as rapidly as otherwise possible. Further, if we do not accurately evaluate the 
commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that 
product through collaboration, license or other royalty arrangements in cases in which it would have been advantageous 
for us to retain sole development and commercialization rights. 

Our product candidates may not successfully complete clinical development or be suitable for successful 
commercialization or generation of revenue through partnerships, and our preclinical programs may not produce 
product candidates that are suitable for clinical trials. 

We must successfully complete preclinical testing, which may include demonstrating efficacy and the lack of 

toxicity in established animal models, before commencing clinical trials for any product candidate. Many pharmaceutical 
and biological product candidates do not successfully complete preclinical testing. There can be no assurance that 
positive results from preclinical studies will be predictive of results obtained from subsequent preclinical studies or 
clinical trials. Even if preclinical testing is successfully completed, we cannot be certain that any product candidates that 
do advance into clinical trials will successfully demonstrate safety and efficacy in clinical trials. Even if we achieve 
positive results in early clinical trials, they may not be predictive of the results in later trials, and safety and/or efficacy 
outcomes of early clinical trials may not be consistent with outcomes of subsequent clinical trials. There can be no 
assurance that we will be able to successfully commercialize our current or future product candidates or to meet our 
expectations with respect to revenues or profits from such products.  

We may incur substantial costs as a result of commercial disputes, claims, litigation or other legal proceedings 
relating to our business operations, especially with regard to patent and other intellectual property rights, and 
such costs or an adverse outcome in such a proceeding may adversely affect our financial condition, results of 
operations and/or stock price. 

Our business involves numerous commercial contractual arrangements, important intellectual property rights, 
potential product liability, uncertainties with respect to clinical development, manufacture and regulatory approvals and 
other aspects that create heightened risks of disputes, claims and legal proceedings. These include claims that may be 
faced in one or more jurisdictions related to the safety of our product candidates and products, the development of our 
product candidates, our ability to obtain regulatory approval for our product candidates, our expectations regarding 
product development and regulatory approval, sales and marketing practices, commercial disputes including with 
contract manufacturers, competition, environmental matters, employment matters and other matters. These matters could 
consume significant time and resources, even if we are successful. Many of our competitors and contractual 
counterparties are significantly larger than we are and, as a result, may be able to sustain the costs of complex litigation 
more effectively than we can because they have substantially greater resources. In addition, we may pay damage awards 
or settlements or become subject to equitable remedies that could, individually or in the aggregate, have a material 
negative effect on our financial condition, results of operations or stock price. Any uncertainties resulting from the 
initiation and continuation of any litigation also could have a material adverse effect on our ability to raise the capital 
necessary to continue our operations. 

We may initiate or become subject to litigation regarding patents and other intellectual property rights. Patent 
infringement litigation involves many complex technical and legal issues and its outcome is often difficult to predict and 

39 

the risk involved in doing so can be substantial. Generic drug manufacturers could seek approval to market a generic 
version of our products or challenge our intellectual property rights with respect to our product candidates. 

It may not be feasible to detect and undertake patent enforcement action to stop infringing activity by a number of 
individual entities, each on a small scale, such as compounding pharmacies. Further, our industry has produced a large 
number of patents and it is not always clear which patents cover various types of products or methods of use. A third 
party may claim that we or our contract manufacturers are using inventions covered by the third party’s patent rights and 
may go to court to stop us from engaging in the alleged infringing activity, including making, using or selling our 
products and product candidates. These lawsuits are costly and could affect our results of operations and divert the 
attention of managerial and technical personnel. There is a risk that a court would decide that we, or our contract 
manufacturers, are infringing the third party’s patents and would order us or our contractors to stop the activities covered 
by the patents. In addition, if we or our contract manufacturers are found to have violated a third party’s patent, we or 
our contract manufacturers could be ordered to pay damages to the other party. We have agreed to or may agree to 
indemnify our contract manufacturers against certain patent infringement claims and thus may be responsible for any of 
their costs associated with such claims and actions. If we were sued for patent infringement, we would need to 
demonstrate that our products and product candidates or methods of use either do not infringe the patent claims of the 
relevant patent or that the patent claims are invalid, and we might be unable to do this. Proving invalidity, in particular, 
is difficult since it requires clear and convincing evidence to overcome the presumption of validity enjoyed by issued 
patents. 

It is difficult and costly to protect our intellectual property and our proprietary technologies, and we may not be 
able to ensure their protection. 

Our commercial success will depend in part on obtaining and maintaining patent protection and trade secret 

protection for the use, formulation and structure of our products and product candidates, the methods used to 
manufacture them, the related therapeutic targets and associated methods of treatment as well as on successfully 
defending these patents against potential third-party challenges. Our ability to protect our products and product 
candidates from unauthorized making, using, selling, offering to sell or importing by third parties is dependent on the 
extent to which we have rights under valid and enforceable patents that cover these activities. 

The patent positions of pharmaceutical, biotechnology and other life sciences companies can be highly uncertain 
and involve complex legal and factual questions for which important legal principles remain unresolved. Changes in 
either the patent laws or in interpretations of patent laws in the U.S. and other countries may diminish the value of our 
intellectual property. Further, the determination that a patent application or patent claim meets all of the requirements for 
patentability is a subjective determination based on the application of law and jurisprudence. The ultimate determination 
by the USPTO or by a court or other trier of fact in the U.S., or corresponding foreign national patent offices or courts, 
on whether a claim meets all requirements of patentability cannot be assured. Although we have conducted searches for 
third-party publications, patents and other information that may affect the patentability of claims in our various patent 
applications and patents, we cannot be certain that all relevant information has been identified. Accordingly, we cannot 
predict the breadth of claims that may be allowed or enforced in our patents or patent applications, in our licensed 
patents or patent applications or in third-party patents. 

We cannot provide assurances that any of our patent applications will be found to be patentable, including over our 

own prior art patents, or will issue as patents. Neither can we make assurances as to the scope of any claims that may 
issue from our pending and future patent applications nor to the outcome of any proceedings by any potential third 
parties that could challenge the patentability, validity or enforceability of our patents and patent applications in the U.S. 
or foreign jurisdictions. Any such challenge, if successful, could limit patent protection for our products and product 
candidates and/or materially harm our business. 

The degree of future protection for our proprietary rights is uncertain because legal means afford only limited 
protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. In addition, 
to the extent that we are unable to obtain and maintain patent protection for one of our products or product candidates or 
in the event that such patent protection expires or is limited to method of use patent protection, it may no longer be cost-

40 

effective to extend our portfolio by pursuing additional development of a product or product candidate for follow-on 
indications. 

We also may rely on trade secrets to protect our technologies or products, especially where we do not believe patent 

protection is appropriate or obtainable. Although we use reasonable efforts to protect our trade secrets, our employees, 
consultants, contractors, outside scientific collaborators and other advisers may unintentionally or willfully disclose our 
information to competitors. Enforcing a claim that a third-party entity illegally obtained and is using any of our trade 
secrets is expensive and time-consuming, and the outcome is unpredictable. In addition, courts outside the U.S. are 
sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop equivalent 
knowledge, methods and know-how. 

Our indebtedness and liabilities could limit the cash flow available for our operations and expose us to risks that 
could adversely affect our business, financial condition and results of operations. 

As of December 31, 2020, we had issued $320.0 million total aggregate principal amount of our 2023 Notes and 

2026 Notes, and we had approximately $1.8 million of outstanding finance lease obligations. We may incur additional 
indebtedness to meet future financing needs. Our existing and future indebtedness could have significant negative 
consequences for our security holders and our business, results of operations and financial condition by, among other 
things: 

• 

• 

• 

• 

• 

• 

requiring a substantial portion of our cash flow from operations to service our indebtedness, which will reduce 
the amount of cash available for other purposes; 

limiting our ability to obtain additional financing; 

limiting our flexibility to plan for, or react to, changes in our business; 

diluting the interests of our existing stockholders as a result of issuing shares of our common stock upon 
conversion of the Convertible Notes;  

placing us at a possible competitive disadvantage with competitors that are less leveraged than we are or have 
better access to capital; and 

increasing our vulnerability to adverse economic and industry conditions. 

Our ability to make scheduled payments of the principal of, to pay interest on, or to refinance our indebtedness, 

including the Convertible Notes, depends on our future performance, which is subject to many factors, including, 
economic, financial, competitive and other circumstances beyond our control. Our business may not generate sufficient 
funds, and we may otherwise be unable to maintain sufficient cash reserves, to pay amounts due under our indebtedness, 
including the Convertible Notes, and our cash needs may increase in the future. In addition, future indebtedness that we 
may incur may contain, financial and other restrictive covenants that limit our ability to operate our business, raise 
capital or make payments under our other indebtedness. If we fail to comply with these covenants or to make payments 
under our indebtedness when due, then we would be in default under that indebtedness, which could, in turn, result in 
that and our other indebtedness becoming immediately payable in full. 

Our competitors may develop products that are less expensive, safer or more effective, or which may otherwise 
diminish or eliminate the success of any products that we may commercialize. 

We may not achieve commercial success if our competitors, many of whom have significantly more resources and 
experience than we, market products that are safer, more effective, less expensive or faster to reach the market than any 
products that we may develop and commercialize. Our competitors also may market a product that proves to be unsafe 
or ineffective, which may affect the market for our competing product, or future product, regardless of the safety or 
efficacy of our product. The failure of OMIDRIA or any future product that we may market to compete effectively with 

41 

products marketed by our competitors would impair our ability to generate revenue, which would have a material 
adverse effect on our future business, our financial condition and our results of operations. 

The loss of members of our management team could substantially disrupt our business operations. 

Our success depends to a significant degree on the continued individual and collective contributions of our 
management team. The members of our management team are at-will employees, and we do not maintain any key-
person life insurance policies other than on the life of Gregory A. Demopulos, M.D., our president, chief executive 
officer and chairman of the board of directors. Losing the services of any key member of our management team, whether 
from death or disability, retirement, competing offers or other causes, without having a readily available and appropriate 
replacement could delay the execution of our business strategy, cause us to lose a strategic partner, or otherwise 
materially affect our operations. 

We rely on highly skilled personnel and, if we are unable to retain or motivate key personnel or hire qualified 
personnel, we may not be able to maintain our operations or grow effectively. 

Our performance is largely dependent on the talents and efforts of highly skilled individuals, many of whom possess 

specialized expertise that may be difficult to replace. Our future success depends on our continuing ability to identify, 
hire, develop, motivate and retain highly skilled personnel for all areas of our organization. If we are unable to hire and 
train a sufficient number of qualified employees for any reason, we may not be able to implement our current initiatives 
or grow effectively. We maintain a rigorous, highly selective and time-consuming hiring process. We believe that our 
approach to hiring has significantly contributed to our success to date. If we do not succeed in attracting qualified 
personnel and retaining and motivating existing personnel, our existing operations may suffer and we may be unable to 
grow effectively. 

We may encounter difficulties managing our growth, which could delay our business plans or adversely affect our 
results of operations. 

To manage our future growth, we must continue to implement and improve our managerial, operational and 
financial systems and continue to recruit, train and retain qualified personnel. We may not be able to implement 
necessary business processes and systems, recruit, train and retain additional qualified personnel and otherwise manage 
the growth of our enterprise due to factors such as limited financial resources and competition for qualified personnel 
within local, national and international markets. The expansion of our operations may lead to significant costs and may 
divert our management and business development resources. Any inability to manage growth could delay the execution 
of our business plans or disrupt our operations. Additionally, our inability to manage growth effectively could cause our 
operating costs to grow even faster than we currently are anticipating. 

Our credit facility contains restrictive covenants that may limit our operating flexibility. 

In August 2019, we entered into a loan and security agreement with Silicon Valley Bank (“SVB”), under which we 

may borrow up to the lesser of $50.0 million and 85.0% of our eligible accounts receivable, less certain reserves. The 
credit facility contains restrictive covenants that limit our ability to transfer or dispose of assets, merge with other 
companies or consummate certain changes of control, acquire other companies, incur additional indebtedness and liens 
and enter into new businesses. We therefore may not be able to engage in any of the foregoing transactions unless we 
obtain the consent of the lender or terminate the credit facility, which may limit our operating flexibility. In addition, our 
credit facility is secured by all of our assets, excluding our intellectual property and development program inventories. 
While we had no outstanding borrowings under the credit facility and were in compliance with all covenants as of 
December 31, 2020, there is no guarantee that we will be able to generate sufficient cash flow or revenue to meet these 
financial covenants or pay the principal and interest on any future borrowings under our facility.  

42 

Product liability claims may damage our reputation and, if insurance proves inadequate, these claims may harm 
our business. 

We may be exposed to the risk of product liability claims that is inherent in the biopharmaceutical industry. A 
product liability claim may damage our reputation by raising questions about our product’s safety and efficacy and could 
limit our ability to sell one or more products by preventing or interfering with commercialization of our products and 
product candidates. In addition, product liability insurance for the biopharmaceutical industry is generally expensive to 
the extent it is available at all. There can be no assurance that we will be able to obtain or maintain such insurance on 
acceptable terms or that we will be able to secure and maintain increased coverage for OMIDRIA or any other product 
we bring to market. Further, our product liability insurance coverage may not provide coverage for or may be 
insufficient to reimburse us for any or all expenses or losses we may suffer. A successful claim against us with respect to 
uninsured liabilities or in excess of insurance coverage could have a material adverse effect on our business, financial 
condition and results of operations. 

We rely on third parties to conduct portions of our preclinical research and clinical trials. If these third parties do 
not perform as contractually required or otherwise expected, or if we fail to adequately supervise or monitor 
these parties, we may not be able to obtain regulatory approval for or commercialize our product candidates. 

We rely on third parties, such as CROs, medical and research institutions and clinical investigators, to conduct a 
portion of our preclinical research, assist us in conducting our clinical trials or to conduct third party-sponsored clinical 
trials of our products and product candidates. Nonetheless, we are responsible for confirming that our preclinical 
research and clinical trials are conducted in accordance with applicable regulations, the relevant trial protocol and within 
the context of approvals by an institutional review board or ethics committee, and we may not always be successful in 
ensuring such compliance. Our reliance on these third parties does not relieve us of responsibility for ensuring 
compliance with FDA and other regulations and standards for conducting, monitoring, recording and reporting the 
results of preclinical research and clinical trials to assure that data and reported results are credible and accurate and that 
the trial participants are adequately protected. If these third parties do not successfully carry out their contractual duties 
or regulatory obligations or meet expected deadlines, if the third parties need to be replaced or if the quality or accuracy 
of the data they obtain is compromised due to their failure to adhere to our clinical protocols or regulatory requirements 
or for other reasons, our preclinical and clinical development processes may be extended, delayed, suspended or 
terminated, and we may not be able to commercialize or obtain regulatory approval for our product candidates. 

We may need to maintain licenses for active ingredients from third parties to develop and commercialize some of 
our product candidates, which could increase our development costs and delay our ability to commercialize those 
product candidates. 

Should we decide to use APIs in any of our product candidates that are proprietary to one or more third parties, such 

as our PDE7 program (OMS527), we would need to maintain licenses to those active ingredients from those third 
parties. If we are unable to continue to access rights to these active ingredients prior to conducting preclinical toxicology 
studies intended to support clinical trials, we may need to develop alternate product candidates from these programs by 
either accessing or developing alternate active ingredients, resulting in increased development costs and delays in 
commercialization of these product candidates. If we are unable to maintain continued access rights to the desired active 
ingredients on commercially reasonable terms or develop suitable alternate active ingredients, or if we do not meet 
diligence or other obligations under the corresponding licenses, we may not be able to commercialize product candidates 
from these programs. 

We use hazardous materials in our business and must comply with environmental laws and regulations, which 
can be expensive. 

Our research operations produce hazardous waste products, which include chemicals and radioactive and biological 

materials. We are subject to a variety of federal, state and local regulations relating to the use, handling, storage and 
disposal of these materials. Although we believe that our safety procedures for handling and disposing of these materials 
comply with applicable legal regulations, the risk of accidental contamination or injury from these materials cannot be 
eliminated. We generally contract with third parties for the disposal of such substances and store our low-level 

43 

radioactive waste at our facility until the materials are no longer considered radioactive. We may be required to incur 
further costs to comply with current or future environmental and safety regulations. In addition, although we carry 
insurance, in the event of accidental contamination or injury from these materials, we could be held liable for any 
damages that result and any such liability could exceed our insurance coverage and other resources. 

General Risk Factors Related to our Business 

Cyber-attacks or other failures in telecommunications or information technology systems could result in 
information theft, data corruption and significant disruption of our business operations. 

We utilize information technology systems and networks to process, transmit and store electronic information in 

connection with our business activities. As use of digital technologies has increased, cyber incidents, including 
deliberate attacks and attempts to gain unauthorized access to computer systems and networks, have increased in 
frequency and sophistication. These threats pose a risk to the security of our systems and networks, the confidentiality 
and the availability and integrity of our data. There can be no assurance that we will be successful in preventing cyber-
attacks or mitigating their effects. Similarly, there can be no assurance that our collaborators, CROs, third-party logistics 
providers, distributors and other contractors and consultants will be successful in protecting our clinical and other data 
that is stored on their systems. Any cyber-attack or destruction or loss of data could have a material adverse effect on our 
business and prospects. In addition, we may suffer reputational harm or face litigation or adverse regulatory action as a 
result of cyber-attacks or other data security breaches and may incur significant additional expense to implement further 
data protection measures.  

Our stock price has been and may continue to be volatile, and the value of an investment in our common stock 
may decline. 

During the 12-month period ended December 31, 2020, our stock traded as high as $25.46 per share and as low as 
$8.50 per share. The trading price of our common stock is likely to continue to be highly volatile and could be subject to 
wide fluctuations in response to numerous factors, many of which are beyond our control. In addition, the stock market 
has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the 
operating performance of publicly traded companies. Broad market and industry factors may seriously affect the market 
price of companies’ stock, including ours, regardless of actual operating performance. These fluctuations may be even 
more pronounced in the trading market for our stock. In addition, in the past, following periods of volatility in the overall 
market and the market price of a particular company’s securities, securities class action litigation has often been 
instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion 
of our management’s attention and resources. 

If we issue additional shares of our common stock or other securities that may be convertible into, or exercisable 
or exchangeable for, our common stock, our existing shareholders would experience further dilution. 

To the extent that we raise additional funds in the future by issuing equity securities, our shareholders would 

experience dilution, which may be significant and could cause the market price of our common stock to decline 
significantly. In addition, approximately 12.2 million shares of common stock were subject to outstanding options and 
warrants as of December 31, 2020 and may become eligible for sale in the public market to the extent permitted by the 
provisions of various vesting agreements. As of December 31, 2020, we also had approximately 4.1 million shares of 
common stock reserved for future issuance under our employee benefit plans that are not subject to outstanding options. 
Further, to the extent we issue common stock upon conversion of the Convertible Notes, such conversion would dilute 
the ownership interests of existing stockholders despite the expected reduction of such dilution as a result of the capped 
call transactions that we entered into in connection with the original issuances of the Convertible Notes. If the holders of 
outstanding options or warrants elect to exercise some or all of them, or if the shares subject to our employee benefit 
plans are issued and become eligible for sale in the public market, or we issue common stock upon conversion of the 
Convertible Notes, our shareholders would experience dilution and the market price of our common stock could decline. 

44 

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

Provisions in our articles of incorporation and bylaws and under Washington law may delay or prevent an 

acquisition of us or a change in our management. These provisions include a classified board of directors, a prohibition 
on shareholder actions by less than unanimous written consent, restrictions on the ability of shareholders to fill board 
vacancies and the ability of our board of directors to issue preferred stock without shareholder approval. In addition, 
because we are incorporated in Washington, we are governed by the provisions of Chapter 23B.19 of the Washington 
Business Corporation Act, which, among other things, restricts the ability of shareholders owning 10% or more of our 
outstanding voting stock from merging or combining with us. Although we believe these provisions collectively provide 
for an opportunity to receive higher bids by requiring potential acquirers to negotiate with our board of directors, they 
would apply even if an offer may be considered beneficial by some shareholders. In addition, these provisions may 
frustrate or prevent any attempts by our shareholders to replace or remove our current management by making it difficult 
for shareholders to replace members of our board of directors, which is responsible for appointing the members of our 
management. 

We have never declared or paid dividends on our capital stock, and we do not anticipate paying dividends in the 
foreseeable future. 

Our business requires significant funding. We currently plan to invest all available funds and future earnings, if any, 
in the development and growth of our business. Additionally, under the loan and security agreement with SVB, we have 
agreed not to pay any dividends. Therefore, we currently do not anticipate paying any cash dividends on our common 
stock in the foreseeable future. As a result, a rise in the market price of our common stock, which is uncertain and 
unpredictable, will be the sole source of potential gain for shareholders in the foreseeable future, and an investment in 
our common stock for dividend income should not be relied upon. 

ITEM 1B.            UNRESOLVED STAFF COMMENTS 

None. 

ITEM 2.              PROPERTIES 

We lease approximately 110,308 square feet for our principal office and laboratory space in the building located at 

201 Elliott Avenue West, Seattle, Washington (“The Omeros Building”), which includes approximately 5,436 square 
feet of laboratory space that we are subleasing to third parties. The lease term for our space is through November 2027. 
We also have two options to extend the lease term, each by five years. The annual base rent due under the lease for our 
principal office and laboratory space is $6.4 million for 2020, $6.5 million for 2021 and $6.7 million for 2022 and will 
increase by approximately 2.3% each year thereafter. In addition, we are responsible for paying our proportionate share 
of the building’s utilities, taxes, insurance and maintenance as well as a property management fee. 

We believe that our facilities are sufficient for our anticipated near-term needs. 

ITEM 3.              LEGAL PROCEEDINGS 

From time to time, in the ordinary course of business, we may be involved in various claims, lawsuits and other 
proceedings. As of the date of filing of this Annual Report on Form 10-K, we were not involved in any material legal 
proceedings.

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

RESULTS OF OPERATIONS 

The following discussion and analysis should be read in conjunction with the audited annual consolidated financial 

statements and the related notes thereto included elsewhere in this Annual Report on Form 10-K. This discussion 
contains forward-looking statements reflecting our current expectations that involve risks and uncertainties. Actual 
results may differ materially from those discussed in these forward-looking statements due to a number of factors, 
including those set forth in the section entitled “Risk Factors” and elsewhere in this Annual Report on Form 10-K. For 
further information regarding forward-looking statements, please refer to the special note regarding forward-looking 
statements at the beginning of this Annual Report on Form 10-K. Throughout this discussion, unless the context specifies 
or implies otherwise, the terms “Company,” “we,” “us” and “our” refer to Omeros Corporation and our wholly owned 
subsidiaries. 

Overview 

We are a commercial-stage biopharmaceutical company committed to discovering, developing and commercializing 

small-molecule and protein therapeutics for large-market as well as orphan indications targeting inflammation, 
complement-mediated diseases, disorders of the central nervous system, and immune-related diseases, including cancers. 

Our drug product OMIDRIA® is marketed in the United States for use during cataract surgery or intraocular lens 

replacement for adult and pediatric patients. Our drug candidate narsoplimab is the subject of a rolling biologics license 
application (“BLA”) under priority review by the U.S. Food and Drug Administration (“FDA”) for the treatment of 
hematopoietic stem cell transplant-associated thrombotic microangiopathy (“HSCT-TMA”). We also have multiple 
Phase 3 and Phase 2 clinical-stage development programs in our pipeline, which are focused on: complement-mediated 
disorders, including immunoglobulin A (“IgA”) nephropathy, atypical hemolytic uremic syndrome (“aHUS”), and 
COVID-19. We have also initiated a Phase 1 clinical program for our MASP-3 inhibitor OMS906 targeting the 
alternative pathway of complement and have successfully completed a Phase 1 study in our phosphodiesterase 7 
(“PDE7”) program focused on addiction. In addition, we have a diverse group of preclinical programs, including 
GPR174, a novel target in immuno-oncology that modulates a new cancer immunity axis that we discovered. Small-
molecule and antibody inhibitors of GPR174 are part of our proprietary G protein-coupled receptor (“GPCR”) platform 
through which we control 54 GPCR drug targets and their corresponding compounds. We also possess a proprietary-
asset-enabled antibody-generating technology. We have retained control of all commercial rights for OMIDRIA and 
each of our product candidates and programs. 

Financial Summary 

We recognized net losses of $138.1 million, $84.5 million, and $126.8 million for the years ended December 31, 
2020, 2019 and 2018, respectively and our OMIDRIA revenues were $73.8 million, $111.8 million, and $29.9 million 

50 

respectively. Historically, OMIDRIA revenues were impacted by the reimbursement status for OMIDRIA under 
Medicare Part B, as well as the COVID-19 pandemic.

*  Fiscal quarters without pass-through reimbursement 

**  Fiscal quarters with reduced cataract procedures due to COVID-19 
***  Pass-through reimbursement expired on October 1, 2020. In 

December 2020, separate payment was confirmed for OMIDRIA, effective 
retroactively as of October 1, 2020. 

During the period from January 1, 2018 to September 30, 2018, OMIDRIA was not reimbursed separately when 

used for procedures involving patients covered by Medicare Part B, and our revenues decreased significantly. After 
reinstatement of pass-through reimbursement for OMIDRIA in the fourth quarter of 2018, our revenues quickly returned 
to levels seen in prior periods during which pass-through reimbursement was available and subsequent quarter-over-
quarter revenue growth approximated historical rates. Pass-through status for OMIDRIA allowed for separate 
reimbursement payment (i.e., outside the packaged procedural payment) to ASCs and hospitals using OMIDRIA in 
procedures involving patients covered by Medicare Part B. 

Pass-through reimbursement for OMIDRIA under Medicare Part B expired on October 1, 2020, and consequently, 

our net revenues for September and the fourth quarter of 2020 were significantly reduced. In December 2020, the 
Centers for Medicare & Medicaid Services (“CMS”) confirmed that OMIDRIA, as an otherwise policy packaged drug 
following OMIDRIA’s expiration of pass-through status on October 1, 2020, qualifies for separate payment when used 
on Medicare Part B patients in the ambulatory surgery center (“ASC”) setting under CMS’ policy for non-opioid pain 
management surgical drugs. CMS made separate payment for OMIDRIA under this policy effective retroactively as of  
October 1, 2020.  CMS’ non-opioid separate payment policy and, as a result, separate payment for OMIDRIA 
thereunder, like other CMS policies in the OPPS and ASC systems, can be changed by CMS through its annual 
rulemaking and comment process for its outpatient prospective payment and ASC payment systems. We believe that 
CMS will continue its separate payment policy for non-opioid pain management surgical drugs, which has been in effect 
since 2019, and that OMIDRIA will continue to be separately reimbursed when used in the ASC setting.  

See Part 1, Item 1, “Business—Commercial Product—OMIDRIA” for additional details regarding the pass-through 

reimbursement status for OMIDRIA. 

We expect our net losses will continue until such time as we derive sufficient revenues from sales of OMIDRIA 
and/or other sources, such as licensing, product sales and other revenues from our product candidates, that are sufficient 
to cover our operating expenses and debt service obligations. 

As of December 31, 2020, we had $135.0 million in cash and cash equivalents and short-term investments available 

for general corporate use and $3.8 million in accounts receivable, net.

Results of Operations 

Revenue 

Our revenue consists of OMIDRIA product sales to ASCs, and hospitals in the U.S. Our product sales, net are as

We launched OMIDRIA in the U.S. in the second quarter of 2015 and sell OMIDRIA primarily through wholesalers 

which, in turn, sell to ASCs and hospitals. 

In 2020, OMIDRIA revenue decreased $38.0 million, or 34%, as compared to the year ended December 31, 2019. 

The decrease in revenue during 2020 compared to 2019 was due to COVID-19-related reductions in the number of 
elective cataract procedures from mid-March 2020 through late June 2020. The additional decrease in revenue during 
2020 compared to 2019 was due to a slowdown in orders from wholesalers during September and the fourth quarter 
following expiration of pass-through reimbursement for OMIDRIA on October 1, 2020. In December 2020, CMS 
confirmed that OMIDRIA qualifies for separate payment when used in the ASC setting. 

In 2019, OMIDRIA revenue increased $81.9 million, or 274%, as compared to the year ended December 31, 2018. 
The increase in revenue in 2019 compared to 2018 was due to significantly increased demand for OMIDRIA by ASCs 
and hospitals following the reinstatement of pass-through reimbursement status for OMIDRIA on October 1, 2018. 

During the nine-month period from January 1, 2018 to September 30, 2018, OMIDRIA was not reimbursed 

separately when used for procedures involving patients covered by Medicare Part B. 

Given the uncertainty and local variances in the severity and response to the COVID-19 pandemic across the U.S., 
and whether CMS will continue its separate payment policy for non-opioid pain management surgical drugs, which has 
been in effect since 2019, we may experience significant fluctuations in period-over-period OMIDRIA revenues. 

Gross-to-Net Deductions 

We record OMIDRIA product sales net of estimated chargebacks, rebates, distribution fees and product returns. 
These deductions are generally referred to as gross-to-net deductions. Our total gross-to-net provisions for the years 
ended December 31, 2020, 2019 and 2018 were 31.2%, 27.7% and 28.1%, respectively, of gross OMIDRIA product 
sales.  

Our gross-to-net provision and payments for the years ended December 31, 2020, 2019 and 2018 are summarized

Chargebacks and Rebates 

We record a provision for estimated chargebacks and rebates at the time we recognize OMIDRIA product sales 

revenue and reduce the accrual when payments are made or credits are granted. Our chargebacks are related to a 
pharmaceutical pricing agreement, a federal supply schedule agreement, a 340B prime vendor agreement, a Medicaid 
drug rebate agreement and an off-invoice discount to our customers. We also record a provision for our 
OMIDRIAssure® patient assistance and reimbursement services program and our rebates under our purchase volume-
discount programs. 

Distribution Fees and Product Return Allowances 

We pay our wholesalers a distribution fee for services they perform for us based on the dollar value of their 
purchases of OMIDRIA. We record a provision for these charges as a reduction to revenue at the time of sale to the 
wholesaler and make payments to our wholesalers based on contractual terms. 

We allow for the return of product up to 12 months past its expiration date, or for product that is damaged or not 
used by our customers. We record a provision for returns upon sale of OMIDRIA to our wholesaler. When a return or 
claim is received, we issue a credit memo to the wholesaler against its outstanding receivable to us or we reimburse the 
customer. 

Research and Development Expenses 

Our research and development expenses can be divided into three categories: direct external expenses, which 
include clinical research and development and preclinical research and development activities; internal, overhead and 
other expenses; and stock-based compensation expense. Direct external expenses consist primarily of expenses incurred 
pursuant to agreements with third-party manufacturing organizations prior to receiving regulatory approval for a product 
candidate, contract research organizations (“CROs”), clinical trial sites, collaborators, and licensors and consultants. 
Costs are reported in preclinical research and development until the program enters the clinic. Internal, overhead and 
other expenses consist of personnel costs, overhead costs such as rent, utilities and depreciation and other miscellaneous 
costs. We do not generally allocate our internal resources, employees and infrastructure to any individual research 
project because we deploy them across multiple clinical and preclinical projects that we are advancing in parallel. 

The following table illustrates our expenses associated with these activities:

Clinical research and development expenses decreased by $0.5 million between 2020 and 2019 due to timing of 

narsoplimab drug manufacturing activities and reduced OMS527 toxicology spending. During 2020, OMS906 clinical 
research and development expenses were $7.2 million, and embedded within pre-clinical research and development costs

were $3.5 million of OMS906-related expenditures. These total expenditures of $10.7 million represent an increase of 
$1.8 million over the prior year.  

The decrease in preclinical research and development expenses in 2020 compared to 2019 is primarily due to the 

migration of OMS906 from preclinical to clinical research and development beginning in the third quarter of 2020. 

The increases in internal, overhead and other expenses in all years presented are primarily due to additional 
employee-related costs and buildout of expanded laboratory facilities in 2020 to support our research and development 
activities. 

We expect overall research and development costs to increase in 2021 as we continue our ongoing Phase 3 clinical 
programs for narsoplimab and manufacture commercial drug substance in anticipation of the drug’s FDA approval for 
the treatment of HSCT-TMA. Our accounting policy is to expense all manufacturing costs incurred until regulatory 
approval is obtained in either the U.S. or Europe. 

At this time, we are unable to estimate with certainty the longer-term costs we will incur in the continued 

development of our product candidates due to the inherently unpredictable nature of our preclinical and clinical 
development activities as well as the potential impact of the COVID-19 pandemic. Clinical development timelines, the 
probability of success and development costs can differ materially as new data become available and as expectations 
change. Our future research and development expenses will depend, in part, on the preclinical or clinical success of each 
product candidate as well as ongoing assessments of each program’s commercial potential. In addition, we cannot 
forecast with precision which product candidates, if any, may be subject to future collaborations, when such 
arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and 
capital requirements. 

We are required to expend substantial resources in the development of our product candidates due to the lengthy 
process of completing clinical trials and seeking regulatory approval. Any failure or delay in completing clinical trials, or 
in obtaining regulatory approvals, could delay our generation of product revenue and increase our research and 
development expenses. 

Selling, General and Administrative Expenses 

Our selling, general and administrative expenses are comprised primarily of salaries, benefits and stock-

compensation costs for sales, marketing and other personnel who are not directly engaged in research and development. 
Costs also include marketing and selling expenses, professional and legal services, general corporate costs and an 
allocation of our occupancy costs.

The increase in selling, general and administrative expenses, excluding stock-based compensation during both years 
ended December 31, 2020 and 2019 was primarily due to increased pre-commercialization activities for narsoplimab for 
the treatment of HSCT-TMA.  

We expect that our selling, general and administrative expenses in 2021 will increase from 2020, primarily due to 

planned U.S. commercialization activities related to narsoplimab.

Interest expense is primarily comprised of contractual interest and amortization of debt issuance and debt discount 

related to our 6.25% Convertible Senior Notes (the “2023 Notes”) and 5.25% Convertible Senior Notes (the “2026 
Notes”) as well as interest on our finance leases. Non-cash interest expense for 2020, 2019 and 2018 was $11.6 million, 
$9.2 million and $5.6 million, respectively. Interest expense increased for each of these periods due to increases in total 
debt outstanding for each period. For more information regarding our debt and our unsecured convertible notes, see 
Part II, Item 8, “Note 7—Debt” and “Note 8—Unsecured Convertible Senior Notes” to our Consolidated Financial 
Statements in this Annual Report on Form 10-K.

issuance costs associated with the repurchased 2023 Notes. 

In November 2018, we issued the 2023 Notes and repaid all previously outstanding loan amounts. We incurred a 

loss on early extinguishment of debt of $13.0 million associated with the unamortized lender facility fee, debt issuance 
costs, debt discount and prepayment fees in connection with the repayment.

Financial Condition - Liquidity and Capital Resources 

As of December 31, 2020, we had $135.0 million in cash, cash equivalents and short-term investments available for 
general corporate use held primarily in money-market accounts as compared to $60.8 million at December 31, 2019. We 
have historically generated net losses and incurred negative cash flows. For the year ended December 31, 2020, we 
incurred net losses of $138.1 million and incurred negative cash flows from operations of $100.1 million. The net loss 
and the negative cash flows from operations were significantly affected by (1) reduced OMIDRIA revenues due to 
uncertainties regarding the reimbursement status of OMIDRIA following expiration of the drug’s pass-through status 
and associated separate payment by CMS on October 1, 2020 and (2) the impact of COVID-19 on the number of cataract 
surgeries performed nationally.  

In December 2020, CMS confirmed that OMIDRIA qualifies for separate payment when used in the ASC setting. 
See Part 1, Item 1, “Business—Commercial Product—OMIDRIA” for additional details regarding the reimbursement 
status for OMIDRIA. 

FDA accepted our BLA for narsoplimab in HSCT-TMA for priority review and has indicated a Prescription Drug 

User Fee Act (“PDUFA”) date of July 17, 2021. We expect to launch narsoplimab commercially for HSCT-TMA in the 
U.S. very soon following FDA approval, and preparations to execute our sales and marketing strategies for launch are 
underway. These plans include various milestones at which we commit to incremental activities, such as field sales 
hiring, and provide for flexibility in the timing of costs incurred should the approval of narsoplimab occur in advance or 
after the current PDUFA date. If warranted, we will adjust the timing and associated costs of our HSCT-TMA launch 
activities as we advance through the BLA review and approval process. 

We plan to continue to fund our operations for at least the next twelve months with our cash and investments on 
hand, from sales of OMIDRIA and, if FDA approval is granted, from sales of narsoplimab for HSCT-TMA. There is 
also the possibility that narsoplimab will generate revenues in the treatment of COVID-19. In addition, we may utilize 
funds available under our accounts receivable-based line of credit, which allows us to borrow up to 85% of our available 
accounts receivable borrowing base less certain reserves or $50.0 million, whichever is less. We may also sell shares of 
our common stock through our “at the market” equity offering program. For additional information regarding this 
program, see Part II, Item 9B, “Other Information.” Should it be necessary or determined to be strategically 
advantageous, we also could pursue debt financings, public and private offerings of our equity securities similar to those 
we have completed previously, or other strategic transactions, which may include licensing all or a portion of any of our 
existing technologies. Should it be necessary to manage our operating expenses, we would reduce our projected cash 
requirements through reduction of our expenses by delaying clinical trials, reducing selected research and development 
efforts, or implementing other restructuring activities.

Operating Activities. Net cash used in operating activities increased for the year ended December 31, 2020 by $40.0 

million compared to the same period in 2019. The difference largely resulted from the $53.6 million increase in our net 
loss from 2019, a $33.0 million increase in cash used in accounts payable and accrued expense, and a $3.6 million 
increase in cash used for prepaid and other assets. These uses were partially offset by a $43.7 million increase in cash 
provided from collections of accounts receivable and an increase in non-cash charges of $5.6 million.

Net cash used in operating activities decreased for the year ended December 31, 2019 by $43.7 million as compared 
to the same period in 2018. The decrease largely resulted from the $42.3 million decrease in our net loss from 2018 due 
to an increase in OMIDRIA product sales of $81.9 million, partially offset by a $33.1 million increase in total cost and 
expenses. In addition, increases in non-cash charges of $6.1 million in 2019 compared to 2018 also positively impacted 
the change in our cash used in operating activities. The net change in operating assets and liabilities of $5.1 million also 
reduced our net cash used in operations for the year ended December 31, 2019 compared to the same period in 2018. 

Investing Activities. Cash flows from investing activities primarily reflect cash used to purchase short-term 
investments and proceeds from the sale of short-term investments, thus causing a shift between our cash and cash 
equivalents and short-term investment balances. Because we manage our cash usage with respect to our cash, cash 
equivalents and short-term investments, we do not consider the fluctuations in cash flows from investing activities to be 
important to the understanding of our liquidity and capital resources.  

Net cash used in investing activities during 2020 was $67.0 million, an increase of $63.6 million from the $3.4 

million net cash used in investing activities for the same period in 2019, driven by an increase in purchases of 
investments of $133.2 million offset by proceeds from sale and maturities of investments of $66.4 million. 

Net cash used investing activities during 2019 was $3.4 million, a decrease of $28.6 million from the $25.2 million 
net cash provided by investing activities for the same period in 2018. The net change in our investments sold compared 
to purchased decreased by $28.8 million providing cash to fund our operations. 

Financing Activities. Net cash provided by financing activities in the year ended December 31, 2020 was $174.5 
million, a net increase of $113.8 million over the same period in 2019. The increase compared to the prior year was due 
to receiving cash proceeds of $76.9 million, net, from the issuance of our 2026 Notes, which includes the payments for 
partial repurchase of our 2023 Notes, payments for debt issuance costs, proceeds from termination of our 2023 capped 
call, and purchases of capped calls related to our 2026 Notes. In addition, we received net proceeds of $93.7 million 
from our August 2020 public offering of our common stock. 

Net cash provided by financing activities in the year ended December 31, 2019 was $60.7 million, a net decrease of 

$20.4 million over the same period in 2018, In December 2019, we received $54.2 million net proceeds from a public 
offering of our common stock. 

Convertible Notes 

For more information regarding the 2023 and 2026 Notes, see Part II, Item 8, “Note 8—Unsecured Convertible 

Senior Notes” to our Consolidated Financial Statements in this Annual Report on Form 10-K. 

Line of Credit 

We have a Line of Credit Agreement, under which we may draw, on a revolving basis, up to the lesser of $50.0 
million and 85.0% of our eligible accounts receivable, less certain reserves. The Line of Credit Agreement is secured by 
all our assets excluding intellectual property and development program inventories and matures on August 2, 2022. As 
of December 31, 2020, we had no outstanding borrowings under the Line of Credit Agreement and we were in 
compliance with all covenants. For more information regarding the Line of Credit Agreement, see Part II, Item 8, 
“Note 7—Debt” to our Consolidated Financial Statements in this Annual Report on Form 10-K.

Operating Leases 

We lease our office and laboratory space in The Omeros Building under a lease agreement with BMR - 201 Elliott 

Avenue LLC. The initial term of the lease ends in November 2027 and we have two options to extend the lease term, 
each by five years. We lease office and laboratory equipment under various operating and finance lease agreements with 
initial terms of five years or less. As of December 31, 2020, the remaining aggregate non-cancelable rent payable under 
the initial term of the lease, excluding common area maintenance and related operating expenses, is $46.6 million. 

Convertible Notes 

Refer to “Financial Condition—Liquidity and Capital Resources—Convertible Notes” above. 

Goods & Services 

We have certain non-cancelable obligations under other agreements for the acquisitions of goods and services 

associated with the manufacturing of our product candidates, which contain firm commitments. As of December 31, 
2020, our aggregate firm commitments are $32.1 million. 

We may be required, in connection with in-licensing or asset acquisition agreements, to make certain royalty and 
milestone payments and we cannot, at this time, determine when or if the related milestones will be achieved or whether 
the events triggering the commencement of payment obligations will occur. Therefore, such payments are not included 
in the table above. For information regarding agreements that include these royalty and milestone payment obligations, 
see Part II, Item 8, “Note 10—Commitments and Contingencies” to our Consolidated Financial Statements in this 
Annual Report on Form 10-K. 

Critical Accounting Policies and Significant Judgments and Estimates 

The preparation of our consolidated financial statements, in conformity with U.S. generally accepted accounting 

principles (“GAAP”), requires management to make estimates and assumptions that affect the amounts reported in the 
financial statements and accompanying notes. We base our estimates on historical experience and on various other 
factors that we believe are reasonable under the circumstances; however, actual results could differ from those estimates. 
An accounting policy is considered critical if it is important to a company’s financial condition and results of operations 
and if it requires the exercise of significant judgment and the use of estimates on the part of management in its 
application. Although we believe that our judgments and estimates are appropriate, actual results may differ materially 
from our estimates. For a summary of our critical accounting policies, See Part II, Item 8, “Note 2—Significant 
Accounting Policies” to our Consolidated Financial Statements in this Annual Report on Form 10-K.

We believe the following to be our critical accounting policies because they are both important to the portrayal of 
our financial condition and results of operations and they require critical judgment by management and estimates about 
matters that are uncertain: 

• 

• 

• 

• 

• 

revenue recognition; 

research and development expenses, primarily related to the manufacturing of drug product;  

accounting for lease agreements, primarily related to our computation of incremental borrowing rate; 

accounting for convertible debt issuances, primarily related to fair valuing debt and issuance costs; and 

stock-based compensation, primarily related to our fair value assumptions. 

If actual results or events differ materially from those contemplated by us in making these estimates, our reported 

financial condition and results of operations for future periods could be materially affected. 

Revenue Recognition 

Product Sales, Net: We typically record revenue from product sales when the product is delivered to our 

wholesalers which is generally when we satisfy all performance obligations. Product sales are recorded net of wholesaler 
distribution fees and estimated chargebacks, rebates, returns and purchase-volume discounts. Accruals or allowances are 
established for these deductions in the same period when revenue is recognized, and actual amounts incurred are offset 
against the applicable accruals or allowances. We reflect each of these accruals or allowances as either a reduction in the 
related accounts receivable or as an accrued liability depending on how the amount is expected to be settled. 

Chargebacks and Rebates: Provisions for chargebacks are determined utilizing historical and projected payer mix 

and information regarding sell-through and inventory on-hand received directly from wholesalers. Chargebacks are 
generally settled within four weeks of recording product sales revenue. 

We provide reimbursement support services and financial assistance in the form of a rebate to patients whose 

commercial insurance is inadequate to cover the full cost of OMIDRIA. We apply an experience ratio based on historical 
and projected patient claims. This experience ratio is applied to product sales to determine the patient rebate accrual and 
is reviewed and updated periodically to reflect actual results. 

We provide rebate payments for which ASCs qualify by meeting or exceeding purchase volumes of OMIDRIA 
under our purchase volume-discount program. We calculate rebate payment amounts due under this program based on 
actual qualifying purchase volumes and apply a contractual discount rate. For purchases of OMIDRIA not yet reported 
as sold-through to the ASC by our wholesalers, we apply an experience ratio to product sales to determine the rebate 
accrual. This experience ratio is reviewed and updated periodically to reflect actual results. 

Distribution Fees and Product Return Allowances: We pay our wholesalers a distribution fee for services that they 

perform for us based on the wholesaler average cost value of their purchases of OMIDRIA. We record a provision 
against product sales for these charges at the time of sale to the wholesaler. 

We allow for the return of product up to 12 months past its expiration date or for product that is damaged. In 
estimating product returns, we take into consideration our return experience to date, the remaining shelf-life of product 
we have previously sold, inventory in the wholesale channel and our expectation that product is typically not held by the 
health care providers based on the frequency of their reorders.  

59 

Research and Development Expenses 

Research and development costs are comprised primarily of: 

• 

• 

• 

• 

• 

• 

contracted research and manufacturing costs;  

clinical study costs;  

costs of personnel, including salaries, benefits and stock compensation; 

consulting arrangements;  

depreciation and an allocation of our occupancy costs; and  

other expenses incurred to sustain our overall research and development programs.  

Contracted research and manufacturing costs are primarily incurred in the development and production of our drug 

substance and drug product candidates. Prior to approval, our estimates are based on the timing of services provided. We 
record accrued expenses equal to our estimated expense in excess of amount invoiced by the suppliers.  

Clinical trial expenses are estimated on a cost per patient that varies depending on the clinical trial site. As actual 
costs become known to us, we adjust our estimates; these changes in estimates may result in understated or overstated 
expenses at any given point in time.  

Right-of-Use Assets and Related Lease Liabilities 

On January 1, 2019, we adopted Accounting Standards Update (ASU) 2016-02, Leases, (Topic 842) using a 
modified retrospective approach versus recasting the prior periods presented. For a summary of the adoption of this 
critical accounting policies, See Part II, Item 8, “Note 2—Significant Accounting Policies” to our Consolidated Financial 
Statements in this Annual Report on Form 10-K. 

We record operating leases on our Consolidated Balance Sheet as right-of-use assets and recognize the related lease 
liabilities equal to the fair value of the lease payments using our incremental borrowing rate when the implicit rate in the 
lease agreement is not readily available. We derived our incremental borrowing rate by assessing rates in recent market 
transactions, as adjusted for security interests and our credit quality. A change in the calculated incremental borrowing 
rate of 100 basis points would not be material to our consolidated financial statements.  

Stock-Based Compensation 

Stock-based compensation expense is recognized for all share-based payments made to employees, directors and 
non-employees based on estimated fair values. The fair value of our stock options is calculated using the Black-Scholes 
option valuation model, which requires assumptions, including volatility, forfeiture rates and expected option life. We 
estimate forfeitures for expense recognition based on our historical experience. Groups of employees that have similar 
historical forfeiture behavior are considered separately. If any of the assumptions used in the Black-Scholes model 
change significantly, stock-based compensation expense for new awards may differ materially from that recorded for 
existing awards and stock-based compensation for non-employees will vary as the awards are re-measured over the 
vesting term. 

Recent Accounting Pronouncements  

Please refer to Part II, Item 8, “Note 2--Significant Accounting Policies” to our Consolidated Financial Statements 

in this Annual Report in Form 10-K for information regarding recent accounting pronouncements.

Off-Balance Sheet Arrangements 

We have not engaged in any off-balance sheet arrangements. 

ITEM 7A.            QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

Our exposure to market risk is primarily confined to our investment securities and debt. The primary objective of 

our investment activities is to preserve our capital to fund operations, and we do not enter into financial instruments for 
trading or speculative purposes. We also seek to maximize income from our investments without assuming significant 
risk. To achieve our objectives, we maintain a portfolio of investments in high-credit-quality securities. As of 
December 31, 2020, we had cash, cash equivalents and short-term investments of $135.0 million. In accordance with our 
investment policy, we invest funds in highly liquid, investment-grade securities. The securities in our investment 
portfolio are not leveraged and are classified as available-for-sale. We currently do not hedge interest rate exposure. 
Because of the short-term maturities of our investments, we do not believe that an increase in market rates would have a 
material negative effect on the realized value of our investment portfolio. We actively monitor changes in interest rates 
and, with our current portfolio of short-term investments, we are not exposed to potential loss due to changes in interest 
rates.

Report of Independent Registered Public Accounting Firm 

To the Shareholders and the Board of Directors 
Omeros Corporation 

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of Omeros Corporation (the Company) as of 
December 31, 2020 and 2019, the related consolidated statements of operations and comprehensive loss, shareholders' 
deficit and cash flows for each of the three years in the period ended December 31, 2020, and the related notes 
(collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all 
material respects, the consolidated financial position of the Company at December 31, 2020 and 2019, and the 
consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 
2020, in conformity with U.S. generally accepted accounting principles.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2020, based on 
criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (2013 framework), and our report dated March 1, 2021 expressed an unqualified opinion 
thereon. 

Adoption of ASU No. 2016-02 

As discussed in Note 2 to the consolidated financial statements, the Company has changed its method for accounting 

for leases in 2019 due to the adoption of ASU No. 2016-02, Leases (Topic 842). 

Basis for Opinion 

These financial statements are the responsibility of the Company's management. Our responsibility is to express an 
opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the 
PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities 
laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.  

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and 

perform the audit to obtain reasonable assurance about whether the financial statements are free of material 
misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material 
misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those 
risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the 
financial statements. Our audits also included evaluating the accounting principles used and significant estimates made 
by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits 
provide a reasonable basis for our opinion. 

Critical Audit Matter 

The critical audit matters communicated below are matters 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 critical audit matters 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 

63 

audit matters below, providing a separate opinion on the critical audit matters or on the accounts or disclosures to which 
they relate. 

Revenue Deductions 

Description of the 
Matter 

    As more fully described in Note 2 of the consolidated financial statements, product sales to wholesalers 
are recorded net of revenue deductions. For the year ended December 31, 2020, revenue deductions 
totaled $33.4 million.  Certain of these revenue deductions require estimates of inventory at wholesalers 
and ASCs as well as the application of an experience ratio based on historical and projected discounts and 
rebate claims. 

Auditing management’s determination of the revenue deductions is complex and requires judgment due 
to the level of estimation involved in management’s assumptions related to inventories held by 
wholesalers and ASCs, and the experience ratio used to estimate unsubmitted claims. 

How We 
Addressed the 
Matter in Our 
Audit 

  We obtained an understanding, evaluated the design, and tested the operating effectiveness of the 

Company’s internal controls over management’s process for estimating inventories in channel and the 
experience ratio. 

To test the revenue deductions, we performed audit procedures that included, among others, evaluating 
the significant assumptions and the accuracy and completeness of underlying data used in management’s 
calculations. We compared the significant assumptions used by management to historical ratios of rebate 
claims to product sales, and other relevant factors. We also assessed the historical accuracy of 
management’s estimates by comparing previous estimates to actual activity in subsequent periods.    

Accounting for convertible senior notes 

Description of the 
Matter 

    During 2020, the Company issued $225 million of 5.25% Convertible Senior Notes due 2026 (the “2026 

Notes”). As discussed in Note 8 of the consolidated financial statements, the 2026 Notes include 
conversion terms that require the Company to account for the debt and equity components of the 
instruments separately, including allocating value to the debt component with the remaining value 
allocated to the equity component reflected as a debt discount to be amortized to interest expense over the 
term of the notes.  

Auditing management’s conclusions related to the value allocated to the debt portion of the Convertible 
Note is complex and involves estimation to determine the effective yield that the Company would have 
received on the debt issuance had it not included a conversion feature. 

How We 
Addressed the 
Matter in Our 
Audit 

  We obtained an understanding, evaluated the design and tested the operating effectiveness of internal 

controls over the Company’s initial 2026 Notes accounting process including controls over the 
Company’s review of the valuation methodology and related key assumptions used to determine the fair 
value of the debt component. 

To test the initial accounting for the 2026 Notes, our audit procedures included, among others, inspection 
of the debt agreement and testing management’s application of the relevant accounting guidance.  To test 
the value assigned to the debt and equity components, we performed audit procedures involving our 
valuation specialists to evaluate the Company’s determination of the fair value of the debt absent of any 
conversion feature. This included testing the appropriateness of the methodology and underlying 
assumptions used, performing independent comparable calculations, and evaluating the sensitivity of 
management’s key assumptions.

OMEROS CORPORATION 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Note 1—Organization and Basis of Presentation 

Organization 

We are a commercial-stage biopharmaceutical company committed to discovering, developing and commercializing 

small-molecule and protein therapeutics for large-market as well as orphan indications targeting inflammation, 
complement-mediated diseases, disorders of the central nervous system, and immune-related diseases, including cancers. 
Our first drug product, OMIDRIA, is marketed in the United States (U.S.) for use during cataract surgery or intraocular 
lens replacement. 

Basis of Presentation 

Our consolidated financial statements include the financial position and results of operations of Omeros Corporation 

(Omeros) and our wholly owned subsidiaries. All inter-company transactions have been eliminated. The accompanying 
consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles 
(GAAP). Certain prior year amounts in the balance sheet, statement of cash flows and the footnotes have been 
reclassified in the consolidated financial statements to conform to the current year presentation. 

Risks and Uncertainties 

Pass-through reimbursement for OMIDRIA under Medicare Part B expired on October 1, 2020, and consequently, 

our net revenues for September and the fourth quarter of 2020 were significantly reduced. In December 2020, the 
Centers for Medicare & Medicaid Services (CMS) confirmed that OMIDRIA, as an otherwise policy packaged drug 
following OMIDRIA’s expiration of pass-through status on October 1, 2020, qualifies for separate payment when used 
on Medicare Part B patients in the ambulatory surgery center (ASC) setting under CMS’ policy for non-opioid pain 
management surgical drugs. CMS made separate payment for OMIDRIA under this policy effective retroactively as of 
October 1. CMS’ current non-opioid separate payment policy and, as a result, separate payment for OMIDRIA 
thereunder, like other CMS policies in the OPPS and ASC systems, can be changed by CMS through its OPPS/ASC 
annual rulemaking and comment process.  

The outbreak of the novel strain of coronavirus that causes COVID-19 and the responses to the global pandemic by 

various governmental authorities, the medical community and others continue to have a significant impact on our 
business. Due to the unknown magnitude, duration and outcome of the COVID-19 pandemic, it is not possible to 
estimate precisely its impact on our business, operations or financial results; however, the impact has been and could 
continue to be substantial. 

We have filed our narsoplimab BLA application for HSCT-TMA with FDA. We anticipate, but cannot warrant, that 

narsoplimab will receive FDA approval and launch in the U.S. in 2021. Currently we cannot fully predict, if and when 
approved, the timing or the magnitude of narsoplimab revenues, but we believe they will be significant. Execution of our 
sales and marketing strategies for the launch of narsoplimab for HSCT-TMA is underway. These plans include various 
milestones at which we commit to incremental activities, providing for flexibility in the timing of costs incurred should 
the approval of narsoplimab be in advance of or following the current PDUFA date. If appropriate, we will adjust the 
timing and associated costs of our HSCT-TMA launch activities as we advance through the BLA review and approval 
process. 

We plan to continue to fund our operations for at least the next twelve months with our cash and investments on 
hand, from sales of OMIDRIA and, if FDA approval is granted, from sales of narsoplimab for HSCT-TMA. In addition, 
we may utilize funds available under our accounts receivable-based line of credit, which allows us to borrow up to 85% 
of our available accounts receivable borrowing base less certain reserves or $50.0 million, whichever is less. We may 
also sell shares of our common stock through our “at the market” equity offering program.  Should it be necessary or 
determined to be strategically advantageous, we also could pursue debt financings, public and private offerings of our 

69 

equity securities similar to those we have completed previously, or other strategic transactions, which may include 
licensing all or a portion of any of our existing technologies. Should it be necessary to manage our operating expenses, 
we would reduce our projected cash requirements through reduction of our expenses by delaying clinical trials, reducing 
selected research and development efforts, or implementing other restructuring activities.  

Segments 

We operate in one segment. Management uses cash flow as the primary measure to manage our business and does 

not segment our business for internal reporting or decision-making. 

Use of Estimates 

The preparation of financial statements in conformity with GAAP requires management to make estimates and 
assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant items 
subject to such estimates include revenue recognition, stock-based compensation expense, and accruals for clinical trials 
and manufacturing of drug product. We base our estimates on historical experience and on various other factors, 
including the impact of the COVID-19 pandemic, that we believe are reasonable under the circumstances; however, 
actual results could differ from these estimates. 

Note 2—Significant Accounting Policies 

Cash and Cash Equivalents, Short-Term Investments and Restricted Investments 

Cash and cash equivalents include highly liquid investments with a maturity of three months or less on the date of 
purchase. Short-term investment securities are classified as available-for-sale and are carried at fair value. Unrealized 
gains and losses, if any, are reported as a separate component of shareholders’ deficit. Amortization, accretion, interest 
and dividends, realized gains and losses and declines in value judged to be other-than-temporary are included in other 
income. The cost of securities sold is based on the specific-identification method. Investments in securities with 
maturities of less than one year, or those for which management intends to use the investments to fund current 
operations, are included in current assets. We evaluate whether an investment is other-than-temporarily impaired based 
on the specific facts and circumstances. Factors that are considered in determining whether an other-than-temporary 
decline in value has occurred include: the market value of the security in relation to its cost basis; the financial condition 
of the investee; and the intent and ability to retain the investment for a sufficient period of time to allow for recovery in 
the market value of the investment. Restricted investments held in money-market funds include security deposits held by 
our landlord. 

As of December 31, 2020 and 2019, all investments are classified as short-term and available-for-sale. Investment 

income, which is included as a component of other income, consists primarily of interest earned. 

Inventory 

Inventory is stated at the lower of cost or market determined on a specific identification basis in a manner that 

approximates the first-in, first-out (FIFO) method. Costs include amounts related to third-party manufacturing, 
transportation and internal labor and overhead. Capitalization of costs as inventory begins when regulatory approval of 
the product candidate is reasonably assured in the U.S. or the European Union (EU). We expense inventory costs related 
to product candidates as research and development expenses prior to receiving regulatory approval in the respective 
territory. Inventory is reduced to net realizable value for excess and obsolete inventories based on forecasted demand. 

Receivables, Net 

Receivables relate primarily to sales of OMIDRIA to wholesalers and include reductions for estimated chargebacks 

and product returns that are expected to be settled through reductions in receivables. Remaining receivables consist of 
amounts from subleases for space in our facilities. Considering the nature and historic collectability of our receivables, 
we concluded an allowance for doubtful accounts is not necessary as of December 31, 2020 and 2019. 

70 

 
 
Property and Equipment, Net 

Property and equipment are stated at cost, and depreciation is calculated using the straight-line method over the 
estimated useful life of the assets, which is generally three to 10 years. Equipment acquired through finance leases is 
recorded as property and equipment and is amortized over the shorter of the useful lives of the related assets or the lease 
term. Expenditures for repairs and maintenance are expensed as incurred. 

Right-of-Use Assets and Related Lease Liabilities 

On January 1, 2019, we adopted Accounting Standards Update (ASU) 2016-02, Leases, (Topic 842) using a 
modified retrospective approach versus recasting the prior periods presented. We elected the package of practical 
expedients permitted under the transition guidance, which allowed us to carryforward our historical assessment of 
whether (i) contracts contain leases, (ii) lease classifications and (iii) initial direct costs. Upon adoption we recognized 
right-of-use assets and lease liabilities of $17.7 million and $26.4 million, respectively. The balance of the net right-of-
use asset included the reversal of the outstanding balance of deferred rent of $8.7 million. 

We record operating leases as right-of-use assets and recognize the related lease liabilities equal to the fair value of 

the lease payments using our incremental borrowing rate when the implicit rate in the lease agreement is not readily 
available. We recognize variable lease payments, when incurred. Costs associated with operating lease assets are 
recognized on a straight-line basis within operating expenses over the term of the lease. 

We record finance leases as a component of property and equipment and amortize these assets within operating 

expenses on a straight-line basis to their residual values over the shorter of the term of the underlying lease or the 
estimated useful life of the equipment. The interest component of a finance lease is included in interest expense and 
recognized using the effective interest method over the lease term.  

We account for leases with initial terms of 12 months or less as operating expenses on a straight-line basis over the 

lease term. 

Unsecured Convertible Senior Notes 

In November 2018, we issued $210.0 million in aggregate principal amount of our 6.25% Convertible Senior Notes 

(the 2023 Notes) and, in August and September 2020, we issued $225.0 million in aggregate principal amount of our 
5.25% Convertible Senior Notes (the 2026 Notes). We used a portion of the proceeds from the 2026 Notes to repurchase 
$115.0 million principal amount of the 2023 Notes and the related capped call (see “Note 8--Unsecured Convertible 
Senior Notes”) and used the remainder for general corporate purposes. 

The 2023 and 2026 Notes are accounted for in accordance with Accounting Standards Codification (ASC) Subtopic 

470-20, Debt with Conversion and Other Options. Pursuant to ASC Subtopic 470-20, we account for convertible debt 
that may be settled wholly or partially in cash upon conversion as having both a liability component (debt) and an equity 
component (conversion option). The cash conversion guidance applies as the embedded conversion features meet the 
requirements for a derivative scope exception for instruments that are both indexed to an entity’s own stock and 
classified in stockholders’ equity in the balance sheet. Principal cash proceeds from the instrument are allocated first to 
the liability component based on the fair value of non-convertible debt using the income and market-based approaches to 
determine an effective interest rate for present valuing the cash proceeds. For the income-based approach, we use a 
convertible bond pricing model that includes several assumptions such as volatility and a risk-free rate. For the market-
based approach, we observe the price of derivative price instruments purchased in conjunction with our convertible 
senior note issuances or evaluate issuances of convertible debt securities by other companies with similar credit risk 
ratings at the time of issuance. The amount of the equity component is then calculated by deducting the fair value of the 
liability component from the principal amount of the instrument. Issuance costs from the instrument are then allocated to 
the liability and equity components in the same proportion as the proceeds. The equity component of the cash principal 
proceeds and the liability component of the issuance costs represent a debt discount, which we amortize as non-cash 
interest expense over the term of the notes using the effective interest rate method.   

71 

Transactions involving contemporaneous exchanges of cash between the same debtor and creditor in connection 

with the issuance of a new debt obligation and satisfaction of an existing debt obligation by the debtor should be 
evaluated as a modification or an exchange transaction depending on whether the exchange is determined to have 
substantially different terms. The 2023 Notes repurchase and issuance of the 2026 Notes were deemed to have 
substantially different terms due to the significant difference between the value of the conversion option immediately 
prior to and after the exchange.  Therefore, the repurchase of the 2023 Notes was accounted for as a debt 
extinguishment. 

Impairment of Long-Lived Assets 

We assess the impairment of long-lived assets, primarily property and equipment, whenever events or changes in 

circumstances indicate that the carrying value of an asset may not be recoverable. Recoverability of these assets is 
measured by comparing the carrying value to future undiscounted cash flows that the asset is expected to generate. If the 
asset is considered to be impaired, the amount of any impairment will be reflected in the results of operations in the 
period of impairment. We have not recognized any impairment losses for the years ended December 31, 2020, 2019 and 
2018. 

Revenue Recognition 

When we enter into a customer contract, we perform the following five steps: (i) identify the contract with a 
customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the 
transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we satisfy a 
performance obligation. 

Product Sales, Net 

We generally record revenue from product sales when the product is delivered to our wholesalers and title for the 
product is transferred. Product sales are recorded net of wholesaler distribution fees and estimated chargebacks, rebates, 
returns and purchase-volume discounts. Accruals or allowances are established for these deductions in the same period 
when revenue is recognized, and actual amounts incurred are offset against the applicable accruals or allowances. We 
reflect each of these accruals or allowances as either a reduction in the related accounts receivable or as an accrued 
liability depending on how the amount is expected to be settled. 

Chargebacks and Rebates 

Provisions for chargebacks are determined utilizing historical and projected payer mix and information regarding 
sell-through and inventory on-hand received directly from wholesalers. Chargebacks are generally settled within four 
weeks of recording product sales revenue. 

We provide reimbursement support services and financial assistance in the form of a rebate to patients whose 

commercial insurance is inadequate to cover the full cost of OMIDRIA. We apply an experience ratio based on historical 
and projected patient claims. This experience ratio is applied to product sales to determine the patient rebate accrual and 
is being reviewed and updated periodically to reflect actual results. 

We provide rebate payments for which ASCs qualify by meeting or exceeding purchase volumes of OMIDRIA 
under our purchase volume-discount program. We calculate rebate payment amounts due under this program based on 
actual qualifying purchase volumes and apply a contractual discount rate. For purchases of OMIDRIA not yet reported 
as sold-through to the ASC by our wholesalers, we apply an experience ratio to product sales to determine the rebate 
accrual. This experience ratio is being reviewed and updated periodically to reflect actual results. 

72 

Distribution Fees and Product Return Allowances 

We pay our wholesalers a distribution fee for services that they perform for us based on the wholesaler average cost 

value of their purchases of OMIDRIA. We record a provision against product sales for these charges at the time of sale 
to the wholesaler.  

We allow for the return of product up to 12 months past its expiration date or for product that is damaged. In 
estimating product returns, we take into consideration our return experience to date, the remaining shelf-life of product 
we have previously sold, inventory in the wholesale channel and our expectation that product is typically not held by the 
health care providers based on the frequency of their reorders. 

Research and Development 

Research and development expenses are comprised primarily of contracted research and manufacturing costs prior 

to approval; costs for personnel, including salaries, benefits and stock compensation; clinical study costs; contracted 
research; manufacturing costs prior to approval; consulting services; depreciation; materials and supplies; milestones; an 
allocation of our occupancy costs; and other expenses incurred to sustain our overall research and development 
programs. Advance payments for goods or services that will be used or rendered for future research and development 
activities are deferred and then recognized as an expense as the related goods are delivered or the services are performed, 
or when the goods or services are no longer expected to be provided. All other research and development costs are 
expensed as incurred.  

Selling, General and Administrative 

Selling, general and administrative expenses are comprised primarily of salaries, benefits, and stock-compensation 
costs for sales, marketing, and other personnel not directly engaged in research and development. Additionally, selling, 
general and administrative expenses include marketing and selling expenses, professional and legal services; patent 
costs; depreciation, an allocation of our occupancy costs; and other general corporate expenses. Advertising costs, which 
we consider to be media and marketing materials, are expensed as incurred and were $5.6 million, $8.0 million and $2.5 
million during the years ended December 31, 2020, 2019 and 2018, respectively. 

Income Taxes 

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between 

the financial statement carrying amounts of existing assets and liabilities and their tax bases. Deferred tax assets and 
liabilities are measured using enacted tax rates applied to taxable income in the years in which those temporary 
differences are expected to be recovered or settled. We recognize the effect of income tax positions only if those 
positions are more likely than not of being sustained upon an examination. A valuation allowance is established when it 
is more likely than not that the deferred tax assets will not be realized. 

Stock-Based Compensation 

 Stock-based compensation expense is recognized for all share-based payments based on estimated fair values. The 

fair value of our stock options is calculated using the Black-Scholes option-pricing model which requires judgmental 
assumptions around volatility, forfeiture rates and expected option term. Compensation expense is recognized over the 
optionees’ requisite service periods, which is generally the vesting period, using the straight-line method. Forfeiture 
expense is estimated at the time of grant and revised in subsequent periods if actual forfeitures differ from those 
estimates. 

Accumulated Other Comprehensive Loss 

Accumulated other comprehensive loss is comprised of net loss and certain changes in equity that are excluded from 
net loss. There was no difference between comprehensive loss and net loss for the years ended December 31, 2020, 2019 
or 2018. 

73 

Financial Instruments and Concentrations of Credit Risk 

Cash and cash equivalents, receivables, accounts payable and accrued liabilities, which are recorded at invoiced 

amount or cost, approximate fair value based on the short-term nature of these financial instruments. The fair value of 
short-term investments is based on quoted market prices. Financial instruments that potentially subject us to 
concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments and receivables. Cash 
and cash equivalents are held by financial institutions and are federally insured up to certain limits. At times, our cash 
and cash equivalents balance held at a financial institution may exceeds the federally insured limits. To limit the credit 
risk, we invest our excess cash in high-quality securities such as money market mutual funds, certificates of deposit and 
commercial paper. 

Major Customers 

We sell OMIDRIA through a limited number of wholesalers. Each of these wholesalers, together with entities under 

their common control, accounted for greater than 10% of our total revenues for the years ended December 31, 2020, 
2019 and 2018 and greater than 10% of accounts receivable as of December 31, 2020, 2019 and 2018 as noted below.

Major Suppliers 

We use a single contract manufacturer to supply the OMIDRIA drug product and a separate company to package 

OMIDRIA for commercial sale. We generally use different contract manufacturers to produce drug substance, drug 
product and to perform final packaging for our drug product candidates. 

We endeavor to maintain reasonable levels of drug supply for our commercial and clinical trial use and other 
manufacturers are available should we need to change suppliers. A change in suppliers, however, could cause a delay in 
delivery of OMIDRIA or our clinical trial material that would adversely affect our business. 

Recent Accounting Pronouncements 

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses, (Topic 326) which changes 
how entities account for credit losses on most financial assets and certain other instruments and expands disclosures. We 
adopted the standard on January 1, 2020 and the adoption did not have a material impact on our consolidated financial 
statements and disclosures. 

In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software, 
(Subtopic 350-40) related to the accounting for cloud computing arrangements to follow the internal-use software 
guidance in determining which development costs to defer and recognize as an asset. We adopted the standard January 1, 
2020 on a prospective basis. 

In August 2020, the Financial Accounting Standards Board issued ASU 2020-06, Debt—Debt with Conversion 
Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40), which 
simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including 
convertible instruments and contracts in an entity’s own equity. Among other changes, ASU 2020-06 removes from U.S. 
GAAP the liability and equity separation model for convertible instruments with a cash conversion feature, and as a 
result, after adoption, entities will no longer separately present in equity an embedded conversion feature for such debt.

Similarly, the embedded conversion feature will no longer be amortized into income as interest expense over the life of 
the instrument. Instead, entities will account for a convertible debt instrument wholly as debt unless (1) a convertible 
instrument contains features that require bifurcation as a derivative under Topic 815, Derivatives and Hedging, or (2) a 
convertible debt instrument was issued at a substantial premium. Among other potential impacts, this change is expected 
to reduce reported interest expense, increase reported net income, and result in a reclassification of certain conversion 
feature balance sheet amounts from stockholders’ equity to liabilities as it relates to the Company’s convertible senior 
notes. Additionally, ASU 2020-06 requires the application of the if-converted method to calculate the impact of 
convertible instruments on diluted earnings per share (EPS), which is consistent with the Company’s accounting 
treatment under the current standard. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, with 
early adoption permitted for fiscal years beginning after December 15, 2020, and can be adopted on either a fully 
retrospective or modified retrospective basis. The Company is evaluating the impact of this pronouncement on its 
consolidated financial statements. 

In December 2019, the Financial Accounting Standards Board issued ASU 2019-12, Income Taxes (Topic 740), 

which is intended to simplify various aspects of the income tax accounting guidance, including elimination of the 
exception to the incremental approach of intra-period tax allocation when there is a loss from continuing operations and 
income or gain from other items (for example, other comprehensive income). ASU 2019-12 is effective for public 
business entities for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. 
Early adoption is permitted, including adoption in an interim period. The Company is evaluating the impact of this 
pronouncement on its consolidated financial statements. 

Note 3—Net Loss Per Share 

Our potentially dilutive securities include potential common shares related to our stock options, warrant and 

unsecured convertible senior notes. Diluted earnings per share (Diluted EPS) considers the impact of potentially dilutive 
securities except in periods in which there is a loss because the inclusion of the potential common shares would have an 
anti-dilutive effect. Diluted EPS excludes the impact of potential common shares related to our stock options in periods 
in which the option exercise price is greater than the average market price of our common stock for the period. 

Potentially dilutive securities excluded from Diluted EPS are as follows: 

Outstanding options to purchase common stock . . . . . . . . . . . . . . . . . . . . . . . . .   
Outstanding warrants to purchase common stock . . . . . . . . . . . . . . . . . . . . . . . .

Note 5—Fair-Value Measurements 

As of December 31, 2020 and 2019, all investments were classified as short-term and available-for-sale. Investment 

income, which was included as a component of other income, consists of interest earned. 

On a recurring basis, we measure certain financial assets at fair value. 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. The 
accounting standard establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs, 
where available. The following summarizes the three levels of inputs required: 

Level 1—Observable inputs for identical assets or liabilities, such as quoted prices in active markets; 

Level 2—Inputs other than quoted prices in active markets that are either directly or indirectly observable; and 

Level 3—Unobservable inputs in which little or no market data exists, therefore they are developed using 

estimates and assumptions developed by us, which reflect those that a market participant would use. 

Our fair-value hierarchy for our financial assets measured at fair value on a recurring basis are as follows:

Cash held in demand deposit accounts of $10.5 million and $3.1 million is excluded from our fair-value hierarchy 
disclosure as of December 31, 2020 and 2019, respectively. There were no unrealized gains or losses associated with our 
short-term investments as of December 31, 2020 or 2019. The carrying amounts for receivables, accounts payable and 
accrued liabilities, and other current monetary assets and liabilities, including lease financing obligations, approximate 
fair value. 

See “Note 8--Unsecured Convertible Senior Notes” for the carrying amount and estimated fair value of our 5.25% 

Convertible Senior Notes due 2026 and 6.25% Convertible Senior Notes due 2023.

Note 7—Debt 

Note Payable 

In October 2016, we entered into a note payable agreement (the Note) with CRG Servicing LLC (“CRG”) and 
borrowed $80.0 million. In May 2018, we borrowed the remaining $45.0 million available under the Note and issued to 
CRG warrants to purchase up to 200,000 shares of our common stock with an exercise price of $23.00 per share and 
total fair value of $1.4 million.  

In November 2018, we issued $210.0 million in principal amount of unsecured convertible senior notes (see 
“Note 8—Unsecured Convertible Senior Notes”) and repaid the Note. Upon repayment, we incurred a loss on early 
extinguishment of debt of $13.0 million associated with the unamortized lender facility fee, debt issuance costs, debt 
discount and prepayment fees upon repayment of the Note. 

Line of Credit 

We have a Loan and Security Agreement with Silicon Valley Bank (SVB), which provides for a $50.0 million 
revolving line of credit facility (the Line of Credit Agreement). Under the Line of Credit Agreement, we may draw, on a 
revolving basis, up to the lesser of $50.0 million and 85.0% of our eligible accounts receivable, less certain reserves. The

Line of Credit Agreement is secured by all our assets excluding intellectual property and development program 
inventories and matures in August 2022. 

Interest on amounts outstanding is payable monthly at a floating rate equal to the greater of 5.50% and the prime 

rate per annum. If the Line of Credit Agreement is terminated prior to the maturity date for any reason other than 
replacement with a new SVB credit facility or a new syndicated facility in which SVB acts as the agent, we are required 
to pay a termination fee of $1.0 million. We paid an initial commitment fee of $150,000 upon closing and are required to 
pay additional commitment fees of $150,000 on each of the first and second anniversaries of the closing date, or upon 
the earlier termination of, or default under, the Line of Credit Agreement. 

The Line of Credit Agreement requires a lockbox arrangement whereby our trade accounts receivable collections are 
deposited into a control account. Amounts deposited in the account are transferred daily to our operating account, except 
that during periods of reduced liquidity or upon an event of default, the amounts received in the control account are 
applied to reduce the outstanding obligations under the Line of Credit Agreement. The Line of Credit Agreement 
includes customary events of default that include, among other things, breach, non-payment, inaccuracy of 
representations and warranties, the occurrence of a material adverse change in our business or prospects for repayment 
of the Line of Credit, cross default to material indebtedness or material agreements, bankruptcy and insolvency, material 
judgments and a change in control. In the event of default, SVB may require all obligations under the Line of Credit 
Agreement to be immediately due and payable and charge a default rate of interest thereon. Additionally, under the loan 
and security agreement with SVB, we have agreed not to pay any dividends. 

As of December 31, 2020, we had no outstanding borrowings under the Line of Credit Agreement. 

Note 8—Unsecured Convertible Senior Notes 

In November 2018, we issued $210.0 million in aggregate principal amount on our 2023 Notes, and in August and 
September 2020, we issued an aggregate principal amount of $225.0 million on our 2026 Notes. We used a portion of 
the proceeds from the 2026 Notes to repurchase $115.0 million principal amount of the 2023 Notes and terminate a 
corresponding portion of the related capped call.

2023 Convertible Senior Notes 

In November 2018, we issued $210.0 million in aggregate principal amount on our 2023 Notes. The 2023 Notes are 

unsecured and accrue interest at an annual rate of 6.25% per annum, payable semi-annually in arrears on May 15 and 
November 15 of each year. The 2023 Notes mature on November 15, 2023 unless earlier purchased, redeemed or 
converted in accordance with their terms. We received net proceeds of $24.0 million as summarized below:

The 2023 Notes are convertible into cash, shares of our common stock or a combination thereof, as we elect at our 

sole discretion. The initial conversion rate is 52.0183 shares of our common stock per $1,000 of note principal 
(equivalent to an initial conversion price of approximately $19.22 per share of common stock), subject to adjustment in 
certain circumstances. To reduce the dilutive impact or potential cash expenditure associated with conversion of the 
2023 Notes, we entered into a capped call transaction (the 2023 Capped Call), which essentially covers the number of 
shares of our common stock underlying the 2023 Notes when our common stock is trading between the initial 
conversion price of $19.22 per share and $28.84 per share. However, should the market price of our common stock 
exceed the $28.84 cap, then the conversion of the 2023 Notes would have an additional dilutive impact or may require a 
cash expenditure to the extent the market price exceeds the cap price. 

In August and September 2020, we issued the 2026 Notes and used approximately $125.6 million of the net 

proceeds to repurchase $115.0 million principal amount of the 2023 Notes (see “2026 Convertible Senior Notes” below). 
The settlement consideration was allocated between the repurchase of the liability and the equity component with the fair 
value of the liability component estimated to be $103.6 million based on the expected future cash flows associated with 
the $115.0 million principal amount discounted at a 9.9% effective interest rate. The remaining $22.0 million was 
accounted for as a repurchase of the equity component, reducing additional paid-in capital. As of the repurchase date of 
August 14, 2020, the carrying value of the repurchased 2023 Notes, net of unamortized debt discount and issuance costs, 
was $90.2 million. The difference between the $103.6 million fair value of the 2023 Notes repurchased and the carrying 
value of $90.2 million resulted in a $13.4 million loss on early extinguishment of debt. After giving effect to the 
repurchase, the total principal amount outstanding under the 2023 Notes as of August 14, 2020 was $95.0 million.   

In connection with the repurchase of $115.0 million in principal amount of the 2023 Notes, we terminated a 

proportionate amount of the related 2023 Capped Call for approximately 6.0 million underlying shares. Upon settlement, 
the Company received $7.5 million in cash and recorded a $0.8 million loss due to the change in fair value of the 
contract between signing and settlement dates. The proceeds were recorded as cash with a corresponding increase in 
additional paid-in capital, and the loss was recorded to other expense in the consolidated statements of operations and 
comprehensive loss. As of December 31, 2020, approximately 4.9 million shares remained outstanding on the 2023 
Capped Call.

The 2026 Notes are unsecured and accrue interest at an annual rate of 5.25% per annum, payable semi-annually in 

arrears on February 15 and August 15 of each year. The 2026 Notes mature on February 15, 2026, unless earlier 
purchased, redeemed or converted in accordance with their terms. 

The initial conversion rate is 54.0906 shares of our common stock per $1,000 of note principal (equivalent to an 

initial conversion price of approximately $18.4875 per share of common stock), which equals approximately 12.2 
million shares issuable upon conversion, subject to adjustment in certain circumstances. 

The 2026 Notes are convertible at the option of the holders on or after November 15, 2025 at any time prior to the 

close of business on February 12, 2026, the second scheduled trading day immediately before the stated maturity date of 
February 15, 2026. Additionally, holders may convert their 2026 Notes at their option at specified times prior to the 
maturity date only if: 

(1)  during any calendar quarter, beginning after September 30, 2020, that the last reported sale price per share of 

our common stock exceeds 130% of the conversion price of the 2026 Notes for each of at least 20 trading days 
in the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately 
preceding calendar quarter; 

(2)  during the five consecutive business days immediately after any five-consecutive-trading-day period (such 
five-consecutive-trading-day period, the “measurement period”) in which the trading price per $1,000 
principal amount of 2026 Notes for each trading day of the measurement period was less than 98% of the 
product of the last reported sale price per share of our common stock on such trading day and the conversion 
rate on such trading day; 

(3)  there is an occurrence of one or more certain corporate events or distributions of our common stock; or 

(4)  we call the 2026 Notes for redemption. 

We may elect, at our sole discretion, to convert the 2026 Notes into cash, shares of our common stock or a 

combination thereof. 

Subject to the satisfaction of certain conditions, we may redeem in whole or in part the 2026 Notes at our option 

beginning August 15, 2023 through the 50th scheduled trading day immediately before the maturity date at a cash 
redemption price equal to the principal amount of the 2026 Notes to be redeemed plus any accrued and unpaid interest 
to, but excluding, the redemption date. The 2026 Notes are subject to redemption only if certain requirements are 
satisfied, including that the last reported sale price per share of our common stock exceeds 130% of the conversion price 
on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and 
including, the trading day immediately before the date we send the related redemption notice and (ii) the trading day 
immediately before the date we send such notice.  

In order to reduce the dilutive impact or potential cash expenditure associated with the conversion of the 2026 
Notes, we entered into capped call transactions in connection with the issuances of the 2026 Notes (the 2026 Capped 
Call). The 2026 Capped Call will cover, subject to anti-dilution adjustments substantially similar to those applicable to 
the 2026 Notes, the number of shares of common stock underlying the 2026 Notes when our common stock is trading 
within the range of approximately $18.49 and $26.10. However, should the market price of our common stock exceed 
the $26.10 cap, then the conversion of the 2026 Notes would have an additional dilutive impact or may require a cash 
expenditure to the extent the market price exceeds the cap price. The 2026 Capped Call will expire on various dates over 
the 50-trading-day period ranging from December 2, 2025 to February 12, 2026, if not exercised earlier. The 2026 
Capped Call is a separate transaction and not part of the terms of the 2026 Notes and was executed separately from the 
issuance of the 2026 Notes. The amount paid for the 2026 Capped Call was recorded as a reduction to additional paid-in 
capital in the condensed consolidated balance sheet. As of December 31, 2020, approximately 12.2 million shares 
remained outstanding under the 2026 Capped Call.

We evaluated the accounting for the issuance of the 2026 Notes and concluded that the embedded conversion 
features meet the requirements for a derivative scope exception for instruments that are both indexed to an entity’s own 
stock and classified in stockholders’ equity in its balance sheet, and that the cash conversion guidance applies. 
Therefore, proceeds of $225.0 million are allocated first to the liability component based on the fair value of non-
convertible debt with the residual proceeds allocated to the equity component for the conversion features. The Company 
allocated $6.8 million in issuance costs associated with the 2026 Notes to the liability and equity component in the same 
proportion as the $225.0 million in proceeds.  

Further, we concluded the 2026 Capped Call qualifies for a derivative scope exception for instruments that are both 
indexed to an entity’s own stock and classified in stockholders’ equity in its balance sheet. Consequently, the fair value 
of the 2026 Capped Call of $23.2 million is classified as equity, not accounted for as derivatives, and will not be 
subsequently remeasured. 

In accounting for the issuance of the 2026 Notes, we separated the 2026 Notes into liability and equity components, 

using an effective interest rate of 12.5% to determine the fair value of the liability component.

As of December 31, 2020, we have committed to additional leased space in the building located at 201 Elliott 
Avenue West, Seattle, Washington (the “Omeros Building”) that will commence in February 2021. The lease terms are 
consistent with our existing leases in The Omeros Building, and the monthly lease payments are approximately $0.1 
million. 

Note 10—Commitments and Contingencies 

Contracts 

We have various agreements with third parties that collectively require payment of termination fees totaling $32.0 

million as of December 31, 2020 if we cancel the work within specific time frames, either prior to commencing or 
during performance of the contracted services. 

Development Milestones and Product Royalties 

We have licensed a variety of intellectual property from third parties that we are currently developing or may 
develop in the future. These licenses may require milestone payments during the clinical development processes as well 
as low single to low double-digit royalties on the net income or net sales of the product. For the year ended 
December 31, 2020, we paid $5.5 million in technology access fees upon entering new agreements. Milestone payments 
were not material for the years ended December 31, 2019 and 2018.

Expected volatility is based on the historical volatility of our stock price weighted by grant issuances over the 
reporting period. We use the simplified method to calculate expected life used in the valuation of our stock options. The 
risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. Forfeiture expense is 
estimated at the time of grant and revised in subsequent periods if actual forfeitures differ from those estimates.

We have a history of losses and therefore have historically not made a provision for income taxes. However, in 2020 

and 2018 we recorded an income tax benefit of $12.0 million and $12.9 million related to the issuance of our 2026 and 
2023 Notes, respectively. In accordance with intra-period tax allocation rules, the deferred tax liability related to the 
equity component of convertible debt is a source of income that can be used to recognize the tax benefit of the 
current year loss through continuing operations. Deferred income taxes reflect the tax effect of net operating loss and tax 
credit carryforwards and the net temporary differences between the carrying amounts of assets and liabilities for 
financial reporting purposes and the amounts used for income tax purposes.

As of December 31, 2020 and 2019, we had federal net operating loss carryforwards of approximately $658.8 
million and $564.3 million, respectively, and state net operating losses of approximately $257.1 million and $170.5 
million, respectively. 

In certain circumstances, due to ownership changes, our net operating loss and tax credit carryforwards may be 

subject to limitations under Section 382 of the Internal Revenue Code. To date, we have not completed a Section 382 
study. Unless previously utilized, net operating losses of $409.0 million generated prior to 2018 will expire between

2021 and 2037. The net operating loss of $144.5 million generated after 2018 should carryforward indefinitely. Unless 
previously utilized, research and development tax credit carryforward will expire between 2021 and 2040. 

We have established a valuation allowance due to the uncertainty of our ability to generate sufficient taxable income 

to realize the deferred tax assets. Our valuation allowance increased $37.8 million and $23.9 million in 2020 and 2019, 
respectively, primarily due to net operating losses incurred during these periods.

We file federal and certain state income tax returns, which provides varying statutes of limitations on assessments. 
However, because of net operating loss carryforwards, substantially all of our tax years remain open to federal and state 
tax examination. 

We recognize interest and penalties related to the underpayment of income taxes as a component of income tax 
expense. To date, there have been no interest or penalties charged to us in relation to the underpayment of income taxes. 

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was enacted and signed 
into law in response to COVID-19. The CARES Act, among other things, includes several significant provisions which 
impact corporate taxpayers' accounting for income taxes, including a modification to the utilization of net operating 
losses and interest expense deduction limitations. The provisions of the CARES Act do not impact our tax provision. 

Note 14—401(k) Retirement Plan 

Our 401(k) retirement plan provides for an annual company discretionary match on employee contributions up to 

4.0% of each participating employee’s eligible earnings, with a maximum company match of $4,000 per employee 
per year. All employees are eligible to participate.

(1)  The COVID-19 pandemic led to a reduction in the number of elective cataract procedures from mid-

March 2020 through late June 2020. In August 2020, the Centers for Medicare and Medicaid Services, the 
federal agency responsible for administering the Medicare program, confirmed the October 1, 2020 expiration 
of pass-through reimbursement for OMIDRIA under Medicare Part B, and consequently, our net revenues for 
September and the fourth quarter of 2020 were significantly reduced. In December 2020, CMS confirmed that 
OMIDRIA qualifies for separate payment when used on Medicare Part B patients in the ASC setting under 
CMS’ policy for non-opioid pain management surgical drugs, effective retroactive as of October 1, 2020.

ITEM 9A.            CONTROLS AND PROCEDURES 

Disclosure Controls and Procedures 

Our management, with the participation of our principal executive officer and principal financial officer, evaluated 

the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the 
Exchange Act, as of December 31, 2020. Management recognizes that any controls and procedures, no matter how well 
designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily 
applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the 
evaluation of our disclosure controls and procedures as of December 31, 2020, our principal executive and principal 
financial officers concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable 
assurance level. 

Management’s Report on Internal Control Over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, 

as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). 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. 

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting 

objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human 
diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal 
control over financial reporting also can be circumvented by collusion or improper management override. Because of 
such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal 
control over financial reporting. However, these inherent limitations are known features of the financial reporting 
process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk. 

Our management, with the participation of our principal executive and principal financial officers, conducted an 
assessment of the effectiveness of our internal control over financial reporting as of December 31, 2020. In making this 
assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway 
Commission in Internal Control-Integrated Framework (2013 framework). Based on the results of this assessment and on 

89 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
  
  
  
  
  
 
 
 
those criteria, our management concluded that our internal control over financial reporting was effective as of 
December 31, 2020. 

Ernst & Young LLP has independently assessed the effectiveness of our internal control over financial reporting as 

of December 31, 2020 and its report is included below. 

There was no change in our internal control over financial reporting identified in connection with the evaluation 

required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during our fourth fiscal quarter of 2020 
that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm 

To the Shareholders and the Board of Directors 
Omeros Corporation 

Opinion on Internal Control over Financial Reporting 

We have audited Omeros Corporation’s internal control over financial reporting as of December 31, 2020, based on 
criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (2013 framework), (the COSO criteria). In our opinion, Omeros Corporation (the Company) 
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on 
the COSO criteria.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the consolidated balance sheets of Omeros Corporation (the Company) as of December 31, 2020 and 
2019, the related consolidated statements of operations and comprehensive loss, shareholders' deficit and cash flows for 
each of the three years in the period ended December 31, 2020, and the related notes of the Company and our report 
dated March 1, 2021 expressed an unqualified opinion. 

Basis for Opinion 

The Company’s management is responsible for maintaining effective internal control over financial reporting and 

for its assessment of the effectiveness of internal control over financial reporting included in the accompanying 
Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion 
on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm 
registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. 
federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the 
PCAOB. 

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and 

perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was 
maintained in all material respects. Our audit included obtaining an understanding of internal control over financial 
reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness 
of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the 
circumstances. We believe that our audit provides a reasonable basis for our opinion. 

Definition and Limitations of Internal Control Over Financial Reporting 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in 
accordance with generally accepted accounting principles. A company’s internal control over financial reporting 
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately 
and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that 
transactions are recorded as necessary to permit preparation of financial statements in accordance with generally 
accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance 
with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a 
material effect on the financial statements.  

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 

Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become

ITEM 9B.            OTHER INFORMATION 

On March 1, 2021, we entered into a sales agreement (the “Sales Agreement”) with Cantor, Fitzgerald & Co. 
(“Cantor”), to sell shares of our common stock having aggregate sales proceeds of up to $150.0 million, from time to 
time, through an “at the market” equity offering program under which Cantor will act as sales agent.  

Under the Sales Agreement, we will set the parameters for the sale of shares of our common stock, including the 
number of shares to be issued, the time period during which sales are requested to be made, and any minimum price 
below which sales may not be made. Subject to the terms and conditions of the Sales Agreement, Cantor will use 
commercially reasonable efforts to sell the shares by methods deemed to be an “at the market offering” as defined in 
Rule 415 under the Securities Act, including sales made directly on The Nasdaq Global Market or any other trading 
market for our common stock. We will pay Cantor a commission of up to 3.0% of the aggregate gross proceeds of any 
common stock sold through Cantor under the Sales Agreement, if any. The Sales Agreement contains customary 
representations, warranties and agreements between us and Cantor, as well as customary indemnification rights, 
including for liabilities under the Securities Act.  

We are not obligated to make any sales of common stock under the Sales Agreement. The offering of shares of 

common stock pursuant to the Sales Agreement will terminate upon the termination of the Sales Agreement in 
accordance with its terms.  We and Cantor may terminate the Sales Agreement at any time by providing written notice to 
the other party. 

The foregoing description of the Sales Agreement is qualified in its entirety by reference to the Sales Agreement, a 

copy of which is attached hereto as Exhibit 1.1 and incorporated herein by reference. The Sales Agreement contains 
representations, warranties and covenants that were made only for purposes of such agreement and as of specific dates, 
are solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the 
contracting parties. The Sales Agreement is not intended to provide any other factual information about us. 

The legal opinion of Keller Rohrback L.L.P. relating to the shares of common stock being offered pursuant to the 

Sales Agreement is filed as Exhibit 5.1 to this Annual Report on Form 10-K.

(1)  Our 2017 Omnibus Incentive Compensation Plan (the “2017 Plan”) provides for the grant of incentive and 

nonstatutory stock options, restricted stock, restricted stock units, stock appreciation rights, performance units and 
performance shares to employees, directors and consultants and subsidiary corporations’ employees and consultants. 
The 2017 Plan replaced the Omeros Corporation 2008 Equity Incentive Plan (the “2008 Plan”), and as a result we 
will not grant any new awards under the 2008 Plan. Any stock option awards granted under the 2008 Plan that were 
outstanding as of the effective date of the 2017 Plan remain in effect pursuant to their terms and, if the award is 
canceled or is repurchased, the shares underlying such award become available for grant under the 2017 Plan.
