Omeros Corporation Reports First Quarter 2021 Financial Results

– Conference Call Today at 4:30 p.m. ET –

Omeros Corporation (Nasdaq: OMER), 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, immunologic diseases (e.g., complement-mediated diseases and cancers) and central nervous system disorders, today announced recent highlights and developments as well as financial results for the first quarter ended March 31, 2021, which include:

• OMIDRIA revenues for the first quarter of 2021 were $21.1 million compared to $10.6 million in the fourth quarter of 2020. The increase over the prior quarter reflects limited fourth-quarter sales due to delayed confirmation (issued in December) by the Centers for Medicare and Medicaid Services (CMS) that OMIDRIA^® (phenylephrine and ketorolac intraocular solution) 1%/0.3% receives separate payment when used in the ambulatory surgery center (ASC) setting.
• Net loss in the first quarter of 2021 was $35.1 million, or $0.57 per share, including non-cash expenses of $4.1 million, or $0.07 per share. This compares to a net loss of $37.3 million, or $0.60 per share, which included non-cash expenses of $3.5 million, or $0.07 per share, for the previous quarter.
• At March 31, 2021, Omeros had cash, cash equivalents and short-term investments available for operations of $100.5 million.
• Dosing of patients with narsoplimab in the I-SPY COVID-19 platform trial began in March 2021. The platform trial, sponsored by Quantum Leap Healthcare Collaborative and partly funded by BARDA, is enrolling patients nationwide to evaluate potential therapies for the treatment of critically ill COVID-19 patients.
• Omeros’ Biologics License Application (BLA) for narsoplimab in the treatment of hematopoietic stem cell transplant-associated thrombotic microangipathy (HSCT-TMA or TA-TMA) is under priority review by the U.S. FDA with an action date of July 17, 2021 under the Prescription Drug User Fee Act (PDUFA).
• In late April, the Centers for Disease Control and Prevention (CDC) and CMS approved a new ICD-10 diagnosis code for TA-TMA, creating a disease-specific code by which facilities will bill for services, and two new ICD-10 procedural codes that allow physicians to bill for the administration of narsoplimab.

“2021 is off to a strong start as we make great progress toward the anticipated launch of narsoplimab for TA-TMA while building momentum with our ophthalmic drug OMIDRIA following CMS’ confirmation of separate payment for OMIDRIA in the ASC setting,” said Gregory A. Demopulos, M.D., Omeros’ chairman and chief executive officer. “Narsoplimab dosing is well underway in the I-SPY COVID-19 platform trial, and the need for a therapeutic to treat critically ill COVID-19 patients is receiving increased focus from both U.S. and international agencies. Looking further across our franchise of complement inhibitors, two other narsoplimab Phase 3 programs are running in IgA nephropathy and aHUS, we expect initial data readout next month from the Phase 1 trial of our MASP-3 inhibitor OMS906, and our subcutaneously delivered long-acting MASP-2 inhibitor OMS1029 is slated to enter the clinic in the first half of next year. Our preclinical programs are also progressing, led by our efforts to deliver a GPR174 inhibitor to the clinic as quickly as possible. With the PDUFA date for narsoplimab in TA-TMA rapidly approaching, we remain committed to bringing a long line of important, first-in-class drugs to market.”

First Quarter and Recent Developments

• Recent developments regarding OMIDRIA include the following:
  • Omeros continued to add new ASC customers in the first quarter of 2021, including seven large ASC chains and private equity groups. The total number of purchasing ASCs increased by 43% in the first quarter over the previous quarter.
  • A manuscript on pain control and reduction of opioid use intraoperatively with the use of OMIDRIA during cataract surgery has been submitted for publication. Another manuscript on the perioperative use of opioids in cataract surgery pain management and the role of non-opioid alternatives like OMIDRIA has also been submitted for publication.
  • The Non-Opioids Prevent Addiction in the Nation (NOPAIN) Act has been re-introduced in the Senate. The NOPAIN Act would extend separate payment for non-opioid alternatives like OMIDRIA in both ASCs and hospital outpatient departments on a renewable five-year basis. Currently, OMIDRIA is separately paid in the ASC setting.
• Recent developments regarding narsoplimab, Omeros’ lead human monoclonal antibody targeting mannan-binding lectin-associated serine protease-2 (MASP-2) in advanced clinical programs for the treatment of TA-TMA, immunoglobulin A (IgA) nephropathy, atypical hemolytic uremic syndrome (aHUS) and critically ill COVID-19 patients, include the following:
  • Data from the pivotal trial of narsoplimab in TA-TMA was featured in a podium presentation at the annual European Society for Blood and Marrow Transplantation (EBMT) meeting in March.
  • An abstract on narsoplimab treatment in adults with high-risk TA-TMA has also been accepted for oral presentation at the 2021 Congress of the European Hematology Association (EHA) in June.
  • Discussions with the U.S. and foreign governments regarding funding and manufacturing support for narsoplimab are ongoing.
• Updates regarding Omeros’ other development programs and platforms include the following:
  • Omeros has completed all of the intravenous cohorts and the first subcutaneous dosing cohort in the single-ascending-dose study in its Phase 1 clinical trial evaluating OMS906, the company’s inhibitor of MASP-3, the key activator of the alternative pathway of complement. Initial data from the placebo-controlled, double-blind, single-ascending-dose and multiple-ascending-dose trial are expected later this quarter.
  • A paper detailing the mechanism of action of PDE7 inhibition in nicotine addiction will soon be published in the peer-reviewed Journal of Neuroscience. Omeros has completed a successful Phase 1 trial with OMS527, its PDE7 inhibitor.

Financial Results

For the first quarter of 2021, OMIDRIA revenues were $21.1 million compared to $10.6 million for the fourth quarter of 2020. The uncertainty around OMIDRIA’s reimbursement status affected revenues in the fourth quarter and extending into early February 2021.

Total costs and expenses for the first quarter of 2021 were $51.7 million compared to $47.2 million for the first quarter of 2020. The increase was primarily due to research and development expenses related to narsoplimab manufacturing. Until approval for narsoplimab in TA-TMA is certain, manufacturing costs for narsoplimab are expensed as incurred instead of included as inventory.

For the three months ended March 31, 2021, Omeros reported a net loss of $35.1 million, or $0.57 per share, which included non-cash expenses of $4.1 million, or $0.07 per share. This compares to a net loss in the previous quarter of $37.3 million, or $0.60 per share, which included non-cash expenses of $3.5 million, or $0.07 per share.

As of March 31, 2021, the company had $100.5 million of cash, cash equivalents and short-term investments. The company also has a line of credit, which permits borrowing up to the lesser of 85 percent of eligible accounts receivable less certain reserves and $50.0 million.

On March 1, 2021, the company entered into an “at the market” sales agreement which allows the company to sell, from time to time, up to $150.0 million of its common stock.
