– Conference Call Friday, November 9th at 8:30 a.m. ET –

SEATTLE--(BUSINESS WIRE)--Nov. 8, 2018-- Omeros Corporation (NASDAQ: OMER) today announced recent highlights and developments as well as financial results for the third quarter ended September 30, 2018, which include:

• 3Q 2018 total and OMIDRIA^® revenues were $4.6 million, compared to $1.7 million in 2Q 2018 and $21.7 million in last year’s third quarter. The increase over the last quarter is primarily due to revenues from the company’s wholesalers in anticipation of renewed buying from ambulatory surgery centers (ASCs) and hospitals as a result of the reinstatement of pass-through reimbursement on October 1, 2018. The decrease from 3Q 2017 is due to the significant reduction in OMIDRIA usage by ASCs and hospitals in 3Q 2018 as a result of the absence of transitional pass-through reimbursement, which expired for OMIDRIA on January 1, 2018.
• Sell-through for October 2018 was 81% of sell-through in October 2017, which was our highest month of OMIDRIA sell-through to date.
• The recently released 2019 Outpatient Prospective Payment System (OPPS) final rule for the Centers for Medicare & Medicaid Services (CMS) includes provisions that are expected to provide for continued separate reimbursement for OMIDRIA after its recently reinstated pass-through status expires on October 1, 2020.
• Net loss in 3Q 2018 was $39.5 million, or $0.81 per share. Non-cash expenses were $5.0 million, or $0.10 per share.
• At September 30, 2018, the company had cash, cash equivalents and short-term investments available for operations of $55.2 million.
• Results from the second reported cohort from Omeros’ ongoing Phase 2 clinical trial in patients with Immunoglobulin A (IgA) nephropathy are consistent with the first cohort and demonstrated significant reductions in proteinuria ranging from greater than 50% to approximately 70% following extended treatment with OMS721.
• Recent meetings with multiple European national regulatory authorities resulted in uniform recommendations to submit a marketing authorization application, or MAA, for full approval of OMS721 for hematopoietic stem cell transplant-associated thrombotic microangiopathy (HSCT-TMA). Based on these meetings, Omeros has filed with the European Medicines Agency (EMA) a letter of intent to submit a marketing authorization application (MAA) via EMA’s centralized procedure for approval of OMS721 for the treatment of HSCT-TMA and expects to receive assignment of a rapporteur and co-rapporteur by year end.
• The U.S. Food and Drug Administration (FDA) granted orphan drug designation to OMS721 for the treatment of HSCT-TMA, and the European Commission adopted a decision designating OMS721 as an Orphan Medicinal Product in the European Union for treatment in HSCT.
• Omeros’ Phase 1 clinical trial for the company’s lead phosphodiesterase 7 (PDE7) inhibitor OMS527 is underway, and the company has completed dosing in the first six cohorts of subjects, which included a food effect study. The compound has been well tolerated, and pharmacokinetic data support once-daily dosing, with or without food.

“We are pleased with the strong demand that we are seeing for OMIDRIA so soon following reinstatement of its pass-through payment status,” said Gregory A. Demopulos, M.D., chairman and chief executive officer of Omeros. “We expect that ramp to continue, generating a growing revenue stream to support our advancing pipeline. Omeros’ lead product in that pipeline, our MASP-2 inhibitor OMS721, is driving toward U.S. and European commercialization in stem-cell TMA, we believe that the recent positive data in IgA nephropathy meaningfully de-risks the program’s Phase 3 pivotal trial, and the aHUS program is enrolling. Our Phase 1 trial for our PDE7 inhibitor OMS527 is progressing nicely and, to date, the drug is demonstrating a good safety profile and predictable pharmacokinetics. OMS906, our MASP-3 inhibitor, is targeted for clinical development in late 2019 followed by our orally administered MASP-2 inhibitors, which are slated to enter the clinic in 2020. Our team has done a great job managing the advancement of these assets while focusing on delivering our products to the market to meet the urgent needs of patients, and I expect that we will see equal or greater achievements in 2019.”

Third Quarter and Recent Developments

• Developments regarding OMIDRIA (phenylephrine and ketorolac intraocular solution) 1% / 0.3% include:
  • Pass-through status for OMIDRIA was reinitiated on October 1, 2018 following a three-quarter hiatus. Sell-through for October 2018 has already reached 81% of sell-through achieved in October 2017, which was our highest month of OMIDRIA sell-through to date.
  • CMS recently released its 2019 final rule for the OPPS. In it, CMS indicated that it will separately pay in the ASC setting for non-opioid drugs used during surgery that have an FDA-approved indication for postoperative pain relief and that are packaged in calendar year 2019. Although OMIDRIA is not specifically named because it is paid separately until October 1, 2020, Omeros believes that OMIDRIA meets the definition for this non-opioid exclusion. The preamble to this section of the OPPS Final Rule indicates that CMS will apply the exclusion from packaged payment to other drugs in the future if they meet the criteria. The OPPS Final Rule also states that CMS will consider in future rulemaking a policy that pays separately for drugs used during cataract surgery that have an FDA-approved indication to address postoperative issues. Omeros believes that OMIDRIA also meets this definition.
  • The most recent manuscripts published or submitted for publication reporting the results of “real-world” clinical studies show that, compared to epinephrine in both conventional and femtosecond-laser assisted cataract surgery, OMIDRIA decreased the need for pupil expansion devices and shortened surgical times for cataract surgery, demonstrating how the use of OMIDRIA may increase the efficiency and reduce the costs of cataract surgery. These studies add to the growing body of published real-world clinical studies demonstrating significant benefits of OMIDRIA to both patients and surgeons across routine and complex cataract surgery cases.
• 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:
  • The company met recently with multiple European national regulatory authorities focused on approval pathways for OMS721 for the treatment of HSCT-TMA. Feedback from the European national regulatory authorities has been uniformly positive, each recommending that Omeros submit an MAA for full approval of OMS721 in HSCT-TMA.
  • The company has filed with the European Medicines Agency a letter of intent to submit an MAA for OMS721 in HSCT-TMA via the centralized procedure and looks forward to receiving assignment of a rapporteur and co-rapporteur who will work with the company through the MAA submission and review process. Close interactions with the FDA and European regulatory agencies are ongoing and the company continues preparations for U.S. Biologics License Application (BLA) and European MAA submissions.
  • The company is preparing to begin collection of chart-review-based historical data following finalization of the data collection and analysis plan. The comparison of OMS721-treated patients to the historical control is designed to support accelerated approval in the U.S. and full approval in Europe.
  • In October 2018, Omeros reported positive results in patients with IgA nephropathy from the second reported cohort of the ongoing Phase 2 clinical trial. The cohort was designed to provide descriptive data on the effects of single and multiple 12-week courses of treatment with OMS721 in a small number of patients. Unlike the first cohort, patients in the second cohort were not taking steroids. Twelve patients were enrolled and data were reported for the nine evaluable patients. At the time of reporting, all patients had completed at least one 12-week course of treatment with either OMS721 or placebo and were eligible for OMS721 treatment during the dosing-extension phase of the study.
    • At week 18, median reduction in proteinuria was 18.4 percent in the five OMS721-treated patients and 18.0 percent in the four placebo patients.
    • Eight patients had at least 18 weeks of data and received at least one 12-week course of treatment with OMS721. In these patients, median reduction from baseline proteinuria was 56 percent; and five of the eight had received only one course of OMS721 treatment.
    • Four patients in this OMS721 dosing-extension period have reached between nine and 12 months beyond baseline, and show reductions in proteinuria of 54 percent, 57 percent, 65 percent, and 68 percent. At most recent assessment, two of these four patients continued to demonstrate sustained reductions in proteinuria for 2.5 and 5 months, respectively, after cessation of treatment with OMS721; the other two patients just recently completed treatment courses.
    • The company and international experts in IgA nephropathy believe that these data are strongly positive and supportive of a disease modifying effect, with the magnitude of proteinuria reduction consistent with that from the previously reported first cohort of the clinical trial.
  • Omeros announced in October 2018 that the FDA granted orphan drug designation to OMS721 for the treatment of HSCT-TMA and announced in July 2018 that the European Commission adopted a decision designating OMS721 as an Orphan Medicinal Product in the European Union for treatment in HSCT.
• In Omeros’ phosphodiesterase 7, or PDE7, program, the company is developing proprietary compounds to treat addiction and compulsive disorders as well as movement disorders. A Phase 1 single-ascending- and multiple-ascending-dose clinical trial is underway with the company’s lead PDE7 inhibitor and is designed to assess safety and pharmacokinetics of the compound in healthy subjects. The company has completed dosing in the first six cohorts of subjects, including one cohort that assessed food effect. The compound to date has been well tolerated and pharmacokinetic data support once-daily dosing, with or without food. Completion of the Phase 1 trial is slated for the first half of 2019. Following Phase 1 completion, if successful, Omeros plans to conduct an initial OMS527 Phase 2 clinical trial in patients with nicotine addiction.

Financial Results

For the quarter ended September 30, 2018, revenues were $4.6 million, all relating to sales of OMIDRIA. This compares to OMIDRIA revenues of $1.7 million in 2Q 2018 and $21.7 million for the third quarter of 2017. The increase over the last quarter is primarily due to revenues from the company’s wholesalers in anticipation of renewed buying from ASCs and hospitals as a result of the reinstatement of pass-through reimbursement on October 1, 2018. The decrease from 3Q 2017 is due to the significant reduction in OMIDRIA use by ASCs and hospitals in 3Q 2018 as a result of the absence of transitional pass-through reimbursement, which expired for OMIDRIA beginning January 1, 2018.

During the last week of September and for October 2018, the company saw OMIDRIA sales from the company’s wholesalers to its customers (sell-through) increase significantly compared to the first three quarters of 2018. In addition, in October 2018, the company’s ASC and hospital customers purchased approximately 17,500 units of OMIDRIA from its wholesalers. October 2017 was the single highest sell-through month for OMIDRIA and in October 2018, the first month of pass-through reinstatement for OMIDRIA, the drug achieved 81% of this record high.

Total costs and expenses for the three months ended September 30, 2018 were $40.1 million compared to $26.8 million for the same period in 2017. The increase from the prior quarter was primarily due to higher manufacturing scale-up costs including the acquisition of manufacturing materials for the OMS721 programs and to incremental costs associated with initiating the OMS721 IgA nephropathy Phase 3 clinical trial and the July 2018 initiation of the company’s Phase 1 clinical trial in OMS527. These increases were partially offset by decreased OMIDRIA patent litigation costs.

For the three months ended September 30, 2018, Omeros reported a net loss of $39.5 million, or $0.81 per share, which included non-cash expenses of $5.0 million ($0.10 per share). In comparison, for the prior year’s third quarter Omeros reported a net loss of $7.5 million, or $0.16 per share including non-cash expenses of $4.2 million ($0.09 per share).

As of September 30, 2018, the company had $55.2 million of cash, cash equivalents and short-term investments available for operations and another $5.8 million in restricted investments.
