Note 1—Description of Business

Description of Business

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, addiction and immune-related diseases, including cancers. Our first drug product, OMIDRIA^® (phenylephrine and ketorolac intraocular solution) 1%/0.3%, is marketed in the United States (“U.S.”) for use during cataract surgery or intraocular lens replacement. In December 2020, the Centers for Medicare & Medicaid Services (“CMS”) confirmed that OMIDRIA qualifies for separate payment when used on Medicare Part B patients in ambulatory surgery centers (“ASCs”), effective retroactively as of October 1, 2020. OMIDRIA’s pass through status, which had allowed for separate payment when used on Medicare Part B patients in the ASC or hospital setting, had expired on October 1, 2020.

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 late-stage clinical 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.

Basis of Presentation

Our condensed consolidated financial statements include the financial position and results of operations of Omeros Corporation (“Omeros”) and our wholly owned subsidiaries. All intercompany transactions have been eliminated, and we have determined we operate in one segment. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The information as of March 31,2021 and December 31, 2020 and for the three months ended March 31, 2021 and 2020 includes all adjustments, which include normal recurring adjustments, necessary to present fairly our interim financial information. The Condensed Consolidated Balance Sheet at December 31, 2020 has been derived from our audited financial statements but does not include all of the information and footnotes required by GAAP for audited annual financial information.

The accompanying unaudited condensed consolidated financial statements and related notes thereto should be read in conjunction with the audited consolidated financial statements and related notes thereto that are included in our Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the U.S. Securities and Exchange Commission (“SEC”) on March 1, 2021.

Risks and Uncertainties

The COVID-19 pandemic and the responses to it by various governmental authorities, the medical community and others have had a significant impact on our business. It is not possible to estimate precisely the future impact of COVID-19 on our business, operations or financial results due to the unknown magnitude, duration and outcome of the pandemic.

We have filed with FDA our narsoplimab BLA for HSCT-TMA, which has been granted priority review with an FDA action date of July 17, 2021 under the Prescription Drug User Fee Act. We anticipate, but cannot guarantee, that narsoplimab will receive FDA approval and will launch in the U.S. in 2021. If approved, we cannot fully predict the timing or the magnitude of narsoplimab revenues, but we believe they will be significant. Our sales and marketing

-8-

Table of Contents

strategies for the launch of narsoplimab for HSCT-TMA include various milestones at which we commit to incremental spending, providing for flexibility in the timing of costs incurred should the approval of narsoplimab be delayed.

We plan to continue to fund our operations for the next twelve months with our cash and investments 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 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 also entered into a sales agreement to sell shares of our common stock, from time to time, up to an aggregate offering amount of $150.0 million through an “at the market” equity offering program. Should it be necessary or determined to be strategically advantageous, we could pursue debt financings as well as public and private offerings of our equity securities, similar to those we have previously completed, or other strategic transactions, which may include licensing a portion of our existing technology. Should it be necessary to manage our operating expenses, we would reduce our projected cash requirements by delaying clinical trials, reducing selected research and development efforts, or implementing other restructuring activities.

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 as well as 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

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.

We generally record revenue from product sales when the product is delivered to our wholesalers. 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.

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.

Right of Use Assets and Related Lease Liabilities

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

-9-

Table of Contents

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.

Stock-Based Compensation

Stock-based compensation expense is recognized for all share-based payments based on estimated fair values as of the date of grant. 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.

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.

Recently Adopted Pronouncements

On January 1, 2021, we adopted Accounting Standard Update (“ASU”) 2020-06, Debt—Debt with Conversion Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40) on a modified retrospective basis. ASU 2020-06 removes the separate liability and equity accounting for our convertible senior notes. Consequently, we now account for our convertible senior notes wholly as debt. (See “Note 3 – Net Loss Per Share” and “Note 7 – Unsecured Convertible Senior Notes” for further information)

On January 1, 2021, we adopted 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). We adopted the standard on a prospective basis and the impact to our consolidated financial statements for the three months ended March 31,2021 was immaterial.

​

​

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. Shares issuable under the unsecured convertible notes are calculated using the if-converted method and are excluded from the below table as their impact is anti-dilutive. 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.

Note 5—Fair-Value Measurements

As of March 31, 2021, and December 31, 2020, all investments were classified as short-term and available-for-sale on the accompanying Condensed Consolidated Balance Sheets. 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 and liabilities measured at fair value on a recurring basis are as follows:

​

​

​

-12-

Table of Contents

Cash held in demand deposit accounts of $9.0 million and $10.5 million is excluded from our fair-value hierarchy disclosure as of March 31, 2021 and December 31, 2020, respectively. There were no unrealized gains or losses associated with our investments as of March 31, 2021 or December 31, 2020. The carrying amounts reported in the accompanying Condensed Consolidated Balance Sheets for receivables, accounts payable, other current monetary assets and liabilities approximate fair value.

See “Note7—Unsecured Convertible Senior Notes” for the carrying amount and estimated fair value of our outstanding convertible senior notes.

Note 6—Line of Credit

We have a Loan and Security Agreement with Silicon Valley Bank, 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 or 85.0% of our eligible accounts receivable, less certain reserves. Interest on amounts outstanding is payable monthly at the greater of 5.5% or the prime rate. The line of credit is secured by all our assets excluding intellectual property and development program inventories.

As of March 31, 2021 and December 31, 2020, no amounts were outstanding under the Line of Credit Agreement.

​

Note 7—Unsecured Convertible Senior Notes

On January 1, 2021, we early adopted ASU 2020-06 on a modified retrospective basis. ASU 2020-06 removes the separate liability and equity accounting for our outstanding convertible senior notes. Consequently, we now account for our convertible senior notes wholly as debt. Adoption of ASU 2020-06 resulted in a cumulative effect adjustment of $75.5 million to restore our unsecured convertible notes and additional paid-in capital to the balances without an equity allocation component. The carrying value of the notes are reflective of their face value less unamortized debt issuance costs. Interest expense recognized in future periods will be reduced as a result of accounting for the unsecured convertible notes wholly as a liability measured at amortized cost.

​

Unsecured convertible senior notes outstanding at March 31, 2021 and December 31, 2020 are as follows:

2023 Unsecured Convertible Senior Notes

On November 15, 2018, we issued $210.0 million in aggregate principal amount of our 6.25% convertible senior notes (the “2023 Notes”). The 2023 Notes 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. On August 14, 2020, we issued the 5.25% convertible senior notes (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 Unsecured Convertible Senior Notes” 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 the conversion of the 2023 Notes, we entered into a capped call transaction (the “2023 Capped Call”), which 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. In connection with the partial repurchase of the 2023 Notes, we entered into a capped call termination contract to unwind a proportionate amount of the 2023 Capped Call. As of March 31, 2021, approximately 4.9 million shares remained outstanding on the 2023 Capped Call.

The following table sets forth total interest expense recognized in connection with the 2023 Notes:

​

Table of Contents

2026 Unsecured Convertible Senior Notes

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. Additionally, holders may convert their 2026 Notes at their option at specified times prior to the maturity date only if:

At our sole discretion, we may elect to convert the 2026 Notes into cash, shares of our common stock or a combination thereof at maturity. Subject to the satisfaction of certain conditions, beginning August 15, 2023, we may redeem in whole or in part the 2026 Notes at our option at a cash redemption price equal to the principal amount of the 2026 Notes plus any accrued and unpaid interest.

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 (the “2026 Capped Calls”). The 2026 Capped Calls will cover 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 a dilutive impact or may require a cash expenditure to the extent the market price exceeds the cap price.

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 in connection with clinical development or commercial milestones as well as low single to low double-digit royalties on the net income or net sales of the product.

Table of Contents

For the three months ended March 31, 2021 and 2020, development milestone expenses were insignificant. We do not owe any royalties on OMIDRIA. Should narsoplimab be approved, we would owe milestone payments to development partners and be obligated to pay low single-digit royalties on net sales of the product.

Note 10—Shareholders’ Deficit

Common Stock and Warrants

On March 1, 2021, we entered into a sales agreement to sell shares of our common stock having an aggregate offering price of up to $150.0 million, from time to time, through an “at the market” equity offering program. As of March 31, 2021, we have not sold any shares under this program.

During the three months ended March 31, 2021, a cashless exercise was executed for 43,115 warrants, resulting in the issuance of 24,901 shares of our common stock. As of March 31, 2021, 200,000 warrants remained outstanding with an exercise price of $23.00 per share. The warrants expire on April 12, 2023.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the unaudited condensed consolidated financial statements and notes thereto included elsewhere in this Quarterly Report on Form 10-Q.

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 late-stage clinical 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 have 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.

Impact of Global Pandemic

The COVID-19 pandemic and the responses to it by various governmental authorities, the medical community and others continue to have a significant impact on our business. In March 2020, ambulatory surgery centers (“ASCs”) and hospitals using OMIDRIA postponed nearly all cataract surgery in response to recommendations from government and medical organizations. As a result, we did not record any sales of OMIDRIA to our wholesalers from March 25 to May 19, 2020. However, by the end of June 2020, the run rate of weekly OMIDRIA sales had recovered to levels approximating those seen prior to the pandemic. It is not possible to estimate precisely the future impact of COVID-19 on our business, operations or financial results due to the unknown magnitude, duration and outcome of the pandemic, especially in light of the severity and transmissibility of virus variants and possible local governmental responses across the U.S.

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

OMIDRIA is approved by FDA for use during cataract surgery or intraocular lens 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: 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.

-19-

Table of Contents

We sell OMIDRIA primarily through wholesalers which, in turn, sell to ASCs and hospitals. The Centers for Medicare & Medicaid Services (“CMS”), the federal agency responsible for administering the Medicare program, granted transitional pass-through reimbursement status for OMIDRIA from January 1, 2015 through December 31, 2017. Pass-through status allows for separate payment (i.e., outside the packaged payment rate for the surgical procedure) under Medicare Part B. In March 2018, Congress extended pass-through reimbursement status for OMIDRIA through September 30, 2020 when used during procedures performed on Medicare Part B fee-for-service patients. Pass-through reimbursement for OMIDRIA under Medicare Part B expired on October 1, 2020. In December 2020, in its annual rule on Outpatient Prospective Payments System (“OPPS”) and ASC payments, CMS confirmed that OMIDRIA qualifies for separate payment when used on Medicare Part B patients in ASCs under CMS’ policy for non-opioid pain management surgical drugs. We believe that CMS will not change its separate payment policy for non-opioid pain management surgical drugs, which has been in effect since 2019.

Clinical Development Programs

Our clinical stage development programs include:

FDA is currently reviewing our BLA 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 a late-stage adaptive platform trial and has been administered under compassionate use to treat COVID-19 patients in Italy and in the U.S.

Narsoplimab has received multiple designations from FDA and from the EMA across three current indications. These include:

In October 2020, we reported final clinical data from our pivotal trial of narsoplimab in HSCT-TMA, a frequently lethal complication of HSCT. The single-arm, open-label trial included safety and efficacy endpoints that 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 November 2020, we completed the rolling submission to FDA of our BLA for narsoplimab for the treatment of HSCT-TMA. The BLA was accepted for filing by FDA and granted priority review, and we have responded to all information requests received to date. The FDA action date under the Prescription Drug User Fee Act (“PDUFA”) is July 17, 2021.

In Europe, the EMA has confirmed narsoplimab’s eligibility for EMA’s centralized review of a single marketing authorization application (“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 our IgA nephropathy program, patient enrollment continues in the narsoplimab Phase 3 clinical trial, 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 one gram per 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 we believe 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 (78 per arm) 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.

The Phase 3 clinical program in patients with aHUS, in which patient enrollment is ongoing, consists of one Phase 3 clinical trial – a single-arm (i.e., no control arm), open-label trial in patients with newly diagnosed or ongoing aHUS. This trial is targeting approximately 40 patients for full approval in Europe and accelerated approval in the U.S. with approximately 80 total patients required by FDA for full approval in the U.S. The trial

includes multiple sites in the U.S., Asia and Europe, though enrollment has been slow in part due to prioritizing the use of resources within our narsoplimab programs on HSCT-TMA, COVID-19 and IgA nephropathy.

The initial cohort treated under this compassionate use program included a total of six COVID-19 patients treated with narsoplimab, 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), 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 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 the above-named 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 and showed 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 continued compassionate-use treatment in the U.S. and Italy. Prior to receiving narsoplimab, all of the patients in this second cohort were severely ill, mechanically ventilated, 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 investigational therapies 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 government agencies, both in the U.S. and internationally, continue to progress.

​

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 dosing all of the intravenous dosing cohorts and the first subcutaneous dosing cohort in the single-ascending dose study. Initial data from the Phase 1 trial are expected in the second quarter of 2021.

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. A manuscript detailing the mechanism of action of PDE7 inhibition in nicotine addiction has been accepted for publication in the peer-reviewed Journal of Neuroscience.

Financial Summary

We recognized net losses of $35.1 million and $29.0 million for the three months ended March 31, 2021 and 2020, respectively, and our OMIDRIA net revenues were $21.1 million and $23.5 million for the same periods. As of March 31, 2021, we had $100.5 million in cash and cash equivalents and short-term investments available for general corporate use and $24.8 million in accounts receivable, net.

​

Pass-through reimbursement for OMIDRIA under Medicare Part B expired on October 1, 2020, which negatively affected our net revenues for September, the fourth quarter of 2020 and the first quarter of 2021. In December 2020, CMS confirmed that OMIDRIA qualifies for separate payment when used on Medicare Part B patients in ASCs. CMS’ current non-opioid separate payment policy can be changed by CMS through its OPPS/ASC annual rulemaking and

comment process. We believe 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 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.

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 follows:

During the three months ended March 31, 2021, OMIDRIA net revenue was $21.1 million as compared to $23.5 million for the three months ended March 31, 2020. The decrease in revenue during the three months ended March 31, 2021 compared to the same period in the prior year was due to the timing of ASCs’ ability to verify reimbursement status following the December confirmation by CMS of separate payment for OMIDRIA before resuming their OMIDRIA usage. The lack of Medicare Part B reimbursement in the hospital setting during the quarter ended March 31, 2021 also contributed to the decrease in revenues. The ongoing COVID-19 pandemic negatively affected the number of cataract procedures performed in the quarter ended March 31, 2020 and, to a lesser extent, the quarter ended March 31, 2021. With separate payment for OMIDRIA established, we expect OMIDRIA revenues to increase during the second quarter.

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 provision for the three months ended March 31, 2021 was 31.5% of gross OMIDRIA product sales compared to 32.3% for the three months ended March 31, 2020. The decrease in gross-to-net deductions as a percentage of sales in 2021 compared to 2020 is due to a reduction in sales returns during the first quarter of 2021 partially offset by an increase in our OMIDRIAssure^® patient assistance and reimbursement program.

A summary of our gross-to-net related accruals for the three months ended March 31, 2021 is as follows:
