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

SEATTLE--(BUSINESS WIRE)--May 10, 2017-- Omeros Corporation (NASDAQ: OMER), a biopharmaceutical company committed to discovering, developing and commercializing both small-molecule and protein therapeutics for large-market as well as orphan indications targeting inflammation, coagulopathies and disorders of the central nervous system, today announced recent highlights and developments as well as financial results for the first quarter of 2017, which include:

• 1Q 2017 total and OMIDRIA^® revenues were $12.3 million. Revenues from OMIDRIA sales rose 69.2% from the prior year’s first quarter.
• OMIDRIA units shipped by wholesalers (“sell-through”) increased 14.2% over 4Q 2016 and 107.2% over 1Q 2016.
• The difference in sell-through and sales revenues in 1Q 2017 was primarily due to transient reductions in wholesaler inventories, which was replenished by wholesaler purchases during the first week in April.
• Net loss in 1Q 2017 was $15.1 million, or $0.34 per share, including $4.4 million ($0.10 per share) of non-cash expenses.
• Positive data were announced from Phase 2 clinical trials of OMS721 in both renal disorders and hematopoietic stem cell transplant-associated thrombotic microangiopathy (HSCT-TMA).
• Successful meeting was held with FDA to discuss OMS721 Phase 3 program for immunoglobin A (IgA) nephropathy; company submitted an application for breakthrough therapy designation.
• Ability to access, at Omeros’ election, $25.0 million debt tranche from affiliates of CRG LP (CRG).

“The first quarter of 2017 was largely a story of progress for OMIDRIA and our MASP-2 inhibitor OMS721,” said Gregory A. Demopulos, M.D., chairman and chief executive officer of Omeros. “Utilization of OMIDRIA continued its double-digit growth as ophthalmic surgeons increasingly recognize the drug’s clinical benefits, driving expansion across and within surgical facilities. We began the quarter with one OMS721 Phase 3 program in aHUS and are now poised to initiate two additional Phase 3 programs in IgA nephropathy and stem cell transplant-associated thrombotic microangiopathies. In addition, one part of our addiction franchise is in Phase 2, the other is expected to enter the clinic early next year and our GPCR program continues to break new ground. Collectively, these achievements and the related milestones that follow we expect bode well for the remainder of 2017 and beyond.”

First Quarter and Recent Highlights and Developments

• Highlights and developments regarding OMS721, Omeros’ lead human monoclonal antibody in its mannan-binding lectin-associated serine protease-2 (MASP-2) programs for the treatment of thrombotic microangiopathies (TMAs), including aHUS and HSCT-TMA, and for the treatment of complement-related renal diseases, including IgA nephropathy, include:
  • In March 2017, Omeros reported positive data from its Phase 2 clinical trial evaluating OMS721 in the treatment of HSCT-TMA. Consistent with previously reported results, statistically significant and clinically meaningful improvements in TMA disease activity were observed over the course of treatment, specifically in mean platelet count, mean lactate dehydrogenase and mean haptoglobin. Mean creatinine also improved but did not reach statistical significance.
  • The company announced positive data from its Phase 2 clinical trial of OMS721 for the treatment of serious kidney disorders, including IgA nephropathy, in March 2017. Treatment effects across all IgA nephropathy patients were consistent, the magnitude of which are associated with improved renal survival. The trial assesses the effect of OMS721 on urine protein measures that are predictive of kidney failure, namely urine albumin-to-creatinine ratio (uACR) and total 24-hour urine protein excretion, and on the ability to reduce steroid dosing. As reported for the three patients who completed treatment, mean improvement in uACR values was 76% and mean decrease in 24-hour urine protein levels was 66%. Concurrently, daily steroid doses for all patients were substantially reduced or completely eliminated.
  • Following discussion with the FDA regarding a Phase 3 program for OMS721 in IgA nephropathy, the company submitted an application for breakthrough therapy designation. Omeros plans to pursue breakthrough therapy or fast track designation for OMS721 in HSCT-TMA. Omeros also is pursuing accelerated approval for OMS721 in aHUS. The FDA has already granted fast track designation for OMS721 in patients with aHUS and orphan designation for OMS721 in patients with complement-mediated TMAs, including aHUS and HSCT-TMA.
  • In February, Phase 2 clinical data in HSCT-TMA were presented at the 2017 Tandem Meeting of the American Society for Blood and Marrow Transplantation and the Center for International Blood and Marrow Transplant Research.
  • In March, a case report describing resolution of HSCT-TMA in a 15-year old patient was presented at the 43rd Annual Meeting of the European Society for Blood and Marrow Transplantation.
  • In April, Phase 2 clinical data in aHUS were presented at the International Society of Nephrology’s World Congress of Nephrology.
• IND-enabling toxicology studies were initiated for OMS527, the company’s phosphodiesterase 7, or PDE7, inhibitor for the treatment of addiction and compulsive disorders.
• CRG has agreed to provide the next tranche of $25.0 million in debt financing under the company’s existing credit facility, which can be drawn at Omeros’ election. The election to borrow must be made by the end of August.

Financial Results

For the quarter ended March 31, 2017, total revenues were $12.3 million, all relating to sales of OMIDRIA. This compares to OMIDRIA revenues of $7.2 million and grant revenue of $173,000 for the same period in 2016. Our 1Q 2017 OMIDRIA revenues decreased from those in 4Q 2016 by $648,000. The decrease was primarily due to the timing of wholesaler orders, resulting in transient reductions in wholesaler inventories at March 31, 2017 compared to December 31, 2016, and, to a lesser extent, the first full quarter of operation for the company’s OMIDRIA purchase volume discount programs. This March 31, 2017 deficit in wholesaler inventories was replenished in the first week of April when wholesalers purchased a net amount of $2.1 million of OMIDRIA, returning inventories to traditional levels and supporting ongoing demand.

OMIDRIA units sold by wholesalers to customers increased 14.2% from 4Q 2016 to 1Q 2017 and 107.2% from 1Q 2016 to 1Q 2017.

Total costs and expenses for the three months ended March 31, 2017 were $25.0 million (including $4.4 million of non-cash expenses) compared to $26.9 million (including $4.7 million of non-cash expenses) for the same period in 2016. The decrease in the first quarter was primarily due to decreased clinical research and development costs associated with the timing of clinical trials and manufacturing and reduced stock compensation. These decreases were partially offset by increased legal costs associated with the Par lawsuit.

Interest expense for the three months ended March 31, 2017 was $2.7 million as compared to $1.4 million in the prior year first quarter. The increase is due to interest on incremental borrowings Omeros made in 2Q and 4Q 2016.

For the three months ended March 31, 2017, Omeros reported a net loss of $15.1 million, or $0.34 per share, which included non-cash expenses of $4.4 million ($0.10 per share). This compares to the prior year’s first quarter, when Omeros reported a net loss of $20.5 million, or $0.54 per share, which included non-cash expenses of $4.7 million ($0.12 per share).
