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

SEATTLE--(BUSINESS WIRE)--May 10, 2018-- Omeros Corporation (NASDAQ: OMER) today announced recent highlights and developments as well as financial results for the first quarter ended March 31, 2018, which include:

• 1Q 2018 total and OMIDRIA^® revenues were $1.6 million, compared to $12.3 million in 1Q 2017; the decrease is the result of the scheduled expiration of OMIDRIA pass-through reimbursement status on January 1, 2018.
• The Consolidated Appropriations Act, signed into law in March 2018, includes a provision granting a two-year pass-through extension, beginning on October 1, 2018, for a small number of drugs including OMIDRIA.
• Net loss in 1Q 2018 was $30.1 million, or $0.62 per share. Non-cash expenses for 1Q 2018 were $4.3 million, or $0.09 per share. Overall decrease in cash, cash equivalents and short-term investments for the quarter was $10.9 million.
• At March 31, 2018, the company had cash, cash equivalents and short-term investments available for operations of $72.8 million. An additional $45.0 million available under the company’s existing credit facility is expected to fund on May 18, 2018.
• Patient enrollment began in the OMS721 Phase 3 clinical trial (known as ARTEMIS-IGAN) in patients with Immunoglobulin A (IgA) nephropathy.
• OMS721 was granted breakthrough therapy designation for treatment of patients with hematopoietic stem cell transplant-associated thrombotic microangiopathy (HSCT-TMA) who have persistent TMA despite modification of immunosuppressive therapy.
• Following recent interactions with FDA, Omeros believes that it has a clear path to approval for OMS721 in high-risk HSCT-TMA, intends to continue working closely with FDA to achieve this objective and has begun preparations to submit a Biologics License Application (BLA).
• OMIDRIA was added to the Veterans Health Administration National Formulary in April 2018.

“During the first quarter of 2018, we made tremendous progress in our MASP-2 program,” said Gregory A. Demopulos, M.D., chairman and chief executive officer of Omeros. “We believe that we now have clear paths to accelerated approval for OMS721 in both stem-cell TMA and IgA nephropathy. With breakthrough therapy designations in both of these indications, we look forward to continuing to work closely with FDA and, for stem-cell TMA, we have initiated preparations for a BLA submission. Our PDE7 inhibitor OMS527 is poised to enter the clinic in mid-year and, in late 2019 through 2020, we expect to begin clinical trials for our MASP-3 antibody OMS906 and for our small-molecule MASP-2 inhibitors. A number of our GPCR programs are also moving toward the clinic, providing the potential for wholly new mechanisms for the treatment of a broad range of diseases and disorders, including cancers. With the Omeros team and the reinstatement of CMS separate payment for OMIDRIA, we believe that we will have the resources to deliver on the immense promise of these programs to benefit patients, many of whom have conditions for which there are no treatments.”

First Quarter and Recent Developments

• Developments regarding OMS721, Omeros’ lead human monoclonal antibody in its mannan-binding lectin-associated serine protease-2 (MASP-2) programs for the treatment of HSCT-TMA, IgA nephropathy, and atypical hemolytic uremic syndrome (aHUS), include:
  • Omeros announced in April 2018 that the U.S. Food and Drug Administration (FDA) granted breakthrough therapy designation to OMS721 for the treatment of patients with high-risk HSCT-TMA, specifically those patients who have persistent TMA despite modification of immunosuppressive therapy. This is the second breakthrough therapy designation for OMS721, which last year received the designation from FDA for the treatment of IgA nephropathy.
  • Omeros recently met with FDA to discuss requirements for approval of OMS721 in high-risk HSCT-TMA. Based on that meeting, Omeros believes that it has clear paths to both accelerated and full approval of OMS721 in this indication. In addition to the data provided to FDA, the Agency requested that the company further characterize the patients treated with OMS721 – all of whom had high-risk TMA – and compile and submit additional information on the historical control population for the purpose of further comparing outcomes across corresponding patients. FDA also requested an analysis plan to assess the company’s biomarker data. Should FDA grant OMS721 accelerated approval for the treatment of high-risk stem cell-TMA patients, the drug would be made commercially available for stem-cell patients with this highly lethal disorder. Concurrently, Omeros would conduct a confirmatory trial for subsequent full approval. Omeros intends to continue working closely with FDA as the company further compiles all required information with the objective of initiating a rolling BLA submission later this year. In Europe, the company is scheduling meetings with regulatory authorities to discuss plans for submission of an application for conditional marketing authorization for OMS721 in HSCT-TMA.
  • In February and April 2018, Omeros reported new results in patients with HSCT-TMA from the ongoing Phase 2 study. The estimated median survival for OMS721-treated patients was an order of magnitude greater than that for a matched historical control (p<0.0001). After study patients had reached an adequate duration of follow-up, further data analysis examined 100-day mortality, an important measure previously used as an approval endpoint in HSCT. That analysis also showed that OMS721-treated patients had improved survival relative to the historical control (53 percent vs 10 percent; p = 0.0002). Biomarkers of disease (i.e., mean platelet count and mean levels of lactate dehydrogenase and haptoglobin), demonstrated statistically significant improvement. Study patients also showed substantial improvement in red blood cell and platelet transfusion requirements.
  • In February 2018, the EMA granted OMS721 orphan drug designation in the treatment of IgA nephropathy. Enrollment in the Phase 3 clinical trial ARTEMIS-IGAN is ongoing.

• Recent developments regarding OMIDRIA include:
  • In March 2018, the Consolidated Appropriations Act, 2018 (Consolidated Appropriations Act) was signed into law and included a two-year extension of pass-through reimbursement status for OMIDRIA and a small number of other drugs used during procedures performed on Medicare Part B fee-for-service patients. As a result, OMIDRIA will receive a reinstatement of separate payment beginning October 1, 2018 through September 30, 2020.
  • OMIDRIA was added to the Veterans Health Administration (VA) National Formulary in April 2018. With its addition to the formulary, the drug is now available in all VA facilities that perform ophthalmic procedures. The initial recommendation is that OMIDRIA be limited to use in high-risk patients as determined by each VA ophthalmic surgeon at his or her discretion.
  • In April 2018, Omeros announced that the results of four “real-world” clinical studies were presented at the American Society of Cataract and Refractive Surgery and American Society of Ophthalmic Administrators Annual Meeting held in Washington, D.C. The studies demonstrate significant benefits of OMIDRIA to both patients and surgeons across routine and complex cataract surgery cases performed in high-volume surgery centers, with and without femtosecond laser.
• In April 2018, the company’s credit facility with CRG was amended to eliminate the revenue and market capitalization covenants with respect to the twelve-month period ending on December 31, 2018 and to reduce the market capitalization threshold for future periods to three times the aggregate principal amount of loans outstanding (excluding any payment-in-kind loans) on the applicable determination date. Omeros issued five-year warrants to the lenders for up to 200,000 shares of the company’s common stock at an exercise price per share of $23.00, which represents approximately a 70-percent premium to the closing price of Omeros’ common stock at that time. In addition, the company has requested the $45.0 million currently available under the CRG credit facility and expects funding to occur on May 18, 2018.

Financial Results

For the quarter ended March 31, 2018, revenues were $1.6 million, all relating to sales of OMIDRIA. This compares to OMIDRIA revenues of $12.3 million for the same period in 2017. On a sequential quarter-over-quarter basis, OMIDRIA revenues decreased $12.2 million, which is attributable to reduced ASC and hospital purchasing following the scheduled loss of pass-through reimbursement status as of January 1, 2018. As part of the Consolidated Appropriations Act, pass-through status for OMIDRIA was reinstated for a two-year period, effective October 1, 2018 through September 30, 2020.

Total costs and expenses for the three months ended March 31, 2018 were $29.3 million compared to $25.0 million for the same period in 2017. The increase in the current year quarter was primarily due to higher manufacturing scale-up costs for the OMS721 programs as Omeros continues to increase production capacity to meet anticipated clinical and commercial requirements as well as to incremental costs associated with initiating the OMS721 IgA nephropathy Phase 3 clinical trial.

For the three months ended March 31, 2018, Omeros reported a net loss of $30.1 million, or $0.62 per share, which included non-cash expenses of $4.3 million ($0.09 per share). In comparison, for the prior year’s first quarter Omeros reported a net loss of $15.1 million, or $0.34 per share including non-cash expenses of $4.4 million ($0.10 per share).

As of March 31, 2018, the company had $72.8 million of cash, cash equivalents and short-term investments available for operations and another $5.8 million in restricted investments. In addition, the company has requested $45.0 million currently available under the company’s existing credit facility and expects funding to occur on May 18, 2018.
