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, complement-mediated diseases, disorders of the central nervous system and immune-related diseases, including cancers, today announced recent highlights and developments as well as financial results for the first quarter ended March 31, 2020, which include:

• Revenues for the first quarter of 2020 were $23.5 million, compared to $21.8 million and $33.4 million in the first and fourth quarters of 2019, respectively. The decrease from the fourth quarter of 2019 reflects the COVID-19-related postponement of cataract procedures by ASCs and hospitals in early March.
• Net loss in the first quarter of 2020 was $29.0 million, or $0.53 per share, including non-cash expenses of $6.4 million, or $0.12 per share. This compares to a net loss of $24.3 million, or $0.50 per share, which included non-cash expenses of $6.0 million, or $0.12 per share, for the comparable quarter in 2019.
• At March 31, 2020, Omeros had cash, cash equivalents and short-term investments available for operations of $54.0 million, a decrease of $6.8 million from December 31, 2019.
• Omeros submitted the second part of its rolling biologics license application (BLA) for narsoplimab for the treatment of hematopoietic stem cell transplant-associated thrombotic microangiopathy (HSCT-TMA). The submission was on schedule and consisted of information relating to the chemistry, manufacturing and controls (CMC) of narsoplimab.

“I am immensely proud of how Omeros’ employees have responded to the unprecedented challenges presented by the global pandemic, adapting to a changing work environment while continuing to meet program milestones with the same commitment, sense of urgency and level of productivity,” said Gregory A. Demopulos, M.D., Omeros’ chairman and chief executive officer. “We already are seeing rapid resumption of OMIDRIA purchases by ASCs and hospitals as they reopen and begin addressing the backlog of cataract surgery patients. For narsoplimab, we just submitted the second part of our rolling BLA as scheduled and continue to target next quarter for its completion. Our ongoing and upcoming clinical programs have weathered COVID-19 well, and we continue to target the start of our OMS906 clinical program next month and data readout from our ARTEMIS-IGAN trial next year. Our research laboratories and nonclinical functions have also remained fully operational. Our preparations for the commercial launch of narsoplimab have accelerated and, with the addition of recent hires, we continue to build top-tier sales, marketing and medical affairs teams. We look forward to adding narsoplimab to what we expect will be a long line of commercial products.”

First Quarter and Recent Developments

• Recent developments regarding OMIDRIA include the following:
  • Previously reported peer-reviewed published data demonstrate that OMIDRIA significantly reduces the need for intraoperative fentanyl, a potent and highly addictive opioid, while significantly decreasing pain scores. A separate study to assess the effect of OMIDRIA on use of postoperative opioid use was also recently completed. In that study an analysis of claims data over a 3-year period was performed by IBM Watson Health. Claims data were evaluated from 218,672 patients 65 years of age or older who underwent cataract surgery. All patients were required to have no opioid use during the 6 months prior to surgery. Filled opioid prescriptions in the OMIDRIA-treated group were compared to those in the non-OMIDRIA-treated group. Patients who received OMIDRIA during surgery received fewer opioid pills in the 2 days and 7 days post-surgery than patients who did not receive OMIDRIA. The median reductions seen were 56 percent (20 pills versus 45 pills) at 2 days (p = 0.015) and 33 percent (40 pills versus 60 pills) at 7 days (p = 0.029). These data provide further evidence that OMIDRIA not only reduces the need for intraoperative fentanyl but also decreases the use of postoperative opioids.
  • The results of a retrospective study of the incidence of postoperative clinical cystoid macular edema (CME), breakthrough iritis, pain and photophobia in patients receiving OMIDRIA were published in the peer-reviewed Journal of Cataract and Refractive Surgery. The study demonstrated with statistical significance that patients receiving OMIDRIA had lower incidences of clinical CME (p = 0.021), breakthrough iritis (p = 0.001) and pain (p = 0.001) compared to a control group receiving conventional perioperative steroids. Patients receiving OMIDRIA also had lower incidence of photophobia, though not statistically significant.
  • A manuscript on the safety and efficacy of OMIDRIA for pediatric cataract surgery was also published by Journal of Cataract and Refractive Surgery. The randomized double-blind study in children undergoing cataract surgery showed that OMIDRIA is safe to use in children and resulted in lower pain scores for patients receiving OMIDRIA than for the control group. As a result, the FDA-approved label for OMIDRIA has no age restriction.
• Recent developments regarding narsoplimab, Omeros’ lead human monoclonal antibody targeting mannan-binding lectin-associated serine protease-2 (MASP-2) in Phase 3 clinical programs for the treatment of HSCT-TMA, Immunoglobulin A (IgA) nephropathy, and atypical hemolytic uremic syndrome (aHUS), include the following:
  • Omeros submitted the second part of its rolling BLA for narsoplimab for the treatment of HSCT-TMA, consisting of CMC-related information, including data on manufacturing, analytical procedures, and associated method validations.
  • A manuscript authored by a group from the University of Leicester led by Dr. Jonathan Barratt PhD, FCRP, Professor of Renal Medicine, has been accepted for peer-reviewed publication. The manuscript describes the beneficial effects of narsoplimab in IgA vasculitis-associated nephritis, a rapidly progressive glomerulonephritis. A second manuscript presenting Omeros’ IgA nephropathy Phase 2 clinical data and authored by the company’s IgA nephropathy Academic Leadership Committee, which is comprised of international thought leaders, has also undergone journal review and is expected to be published soon.
  • Consistent with FDA guidelines and recommendations of the independent data safety monitoring committee regarding ongoing clinical trials during the COVID-19 pandemic, study sites for Omeros’ ongoing Phase 3 programs for narsoplimab in IgA nephropathy and aHUS are conducting trials in a manner consistent with local recommendations and/or regulations to maintain safety of study patients. As a result, at some sites, new patient enrollment has slowed while previously enrolled patients are continuing in the trials. We continue targeting data readout for the IgA nephropathy trial next year.
• Updates regarding Omeros’ other development programs and platforms include the following:
  • First-in-human-enabling toxicology studies for the company’s MASP-3 inhibitor OMS906 are complete. Omeros is on track to file a clinical trial application this quarter and to begin dosing in the first part of the third quarter.
  • As part of the strategy for life-cycle management of the company’s complement franchise, Omeros continues to develop a longer-acting second generation antibody against MASP-2, which is targeted to enter the clinic in early 2022, to be followed by an orally available small molecule inhibitor against MASP-2 also under development.

Financial Results

For the first quarter of 2020, revenues, all related to sales of OMIDRIA, were $23.5 million, compared to $21.8 million for the same period in 2019 and a record-high $33.4 million for the fourth quarter of 2019. The decrease from the prior quarter reflects declining sales beginning in early March, as a result of inventory utilization by ASCs and hospitals in anticipation of the COVID-19-related shutdown of elective surgical procedures, which occurred in mid-March. Sales of OMIDRIA to wholesalers were minimal in March. March typically accounts for about 45 percent of total first-quarter OMIDRIA revenues, and Omeros realized only one week of March revenues. In early May, a large number of states began re-opening ASCs and hospitals to cataract surgery, and facilities in at least 36 states have already initiated re-ordering of OMIDRIA from wholesalers.

Total costs and expenses for the first quarter of 2020 were $47.2 million compared to $41.0 million for the comparable period in 2019. The increase was due to increased research and development and pre-commercialization marketing activities for narsoplimab.

For the three months ended March 31, 2020, Omeros reported a net loss of $29.0 million, or $0.53 per share, which included non-cash expenses of $6.4 million, or $0.12 per share. This compares to a net loss of $24.3 million, or $0.50 per share, which included non-cash expenses of $6.0 million, or $0.12 per share, for the comparable quarter in 2019.

As of March 31, 2020, the company had $54.0 million of cash, cash equivalents and short-term investments available for operations, a decrease $6.8 million from December 31, 2019. The company also has a line of credit, which permits borrowing up to the lesser of 85 percent of eligible accounts receivable and $50 million. As of March 31, 2020, the eligible accounts receivable balance was $24.1 million, and Omeros has not borrowed under this facility.
