Omeros Corporation Reports Third Quarter 2020 Financial Results

SEATTLE, WA – November 9, 2020 – 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 third quarter ended September 30, 2020, which include:

● Revenues for the third quarter of 2020 were $26.1 million following an $8.7 million deduction as a return reserve associated with the expiration of pass-through reimbursement for OMIDRIA on October 1, 2020. Omeros believes that it qualifies for and is pursuing separate payment from the Centers for Medicare and Medicaid Services (CMS) for OMIDRIA. For comparison, third quarter 2019 and second quarter 2020 revenues were $29.9 million and $13.5 million, respectively.

● Net loss in the third quarter of 2020 was $38.5 million, or $0.66 per share, of which $13.6 million, or $0.23 per share, were non-cash expenses. This compares to a net loss of $16.5 million, or $0.33 per share, in the third quarter of 2019. On a non-GAAP basis, adjusted net loss for the third quarter of 2020 was $19.9 million, or $0.34 per share, after excluding non-cash expenses and a $5.0 million technology access fee. Net loss and adjusted net loss include the $8.7 million deduction in third quarter 2020 revenues for the return reserve.

● At September 30, 2020, the company had cash, cash equivalents and short-term investments available for operations of $153.5 million. This includes $93.7 million in proceeds from a common stock offering and $76.9 million in proceeds from the issuance of convertible notes, following the use of a portion of the proceeds to repurchase a portion of our previously outstanding convertible notes and enter into certain derivative transactions, all of which took place during the third quarter.

● Omeros will complete submission next week to the U.S. Food and Drug Administration (FDA) of its rolling Biologics License Application (BLA) for narsoplimab for the treatment of hematopoietic stem cell transplant-associated thrombotic microangiopathy (HSCT-TMA or TA-TMA). Final clinical data from the BLA were presented in a webcast last month, as described below.

● In August, Omeros reported results from a study evaluating narsoplimab for treatment of COVID-19-associated acute respiratory distress syndrome (ARDS). Six COVID-19 patients in Bergamo, Italy were treated with narsoplimab. All six patients required mechanical ventilation prior to narsoplimab treatment, and each recovered, survived and was discharged from the hospital following treatment. Two historical control groups that had similar baseline characteristics showed mortality rates of 32 percent and 53 percent. The results of the trial were published in the peer-reviewed journal Immunobiology. Five to six months after cessation of narsoplimab dosing, all patients were doing well and none showed clinical or laboratory evidence of longer-term effects from COVID-19.

● In September, Omeros initiated its Phase 1 clinical trial for OMS906, the company’s MASP-3 inhibitor targeting the alternative pathway, and has completed dosing in the first patient cohort.

“The final clinical study results for narsoplimab in the treatment of transplant-associated TMA speak for themselves. The non-clinical and CMC sections of the BLA are under review by FDA, and the clinical sections, which will be submitted next week, are complete, comprehensive and compelling,” said Gregory A. Demopulos, M.D., Omeros’ chairman and chief executive officer. “In anticipation of priority review, our team is readying for a successful commercial launch.

Beyond TA-TMA and its Phase 3 trials in IgA nephropathy and aHUS, narsoplimab is increasingly recognized as a likely answer to severe COVID-19. Our complement franchise continues expanding with our MASP-3 inhibitor OMS906 on course and marching through its Phase 1 program. Confident that OMIDRIA qualifies for separate payment from CMS, we expect that the drug will increasingly support our unique portfolio of complement inhibitors and the rest of our exciting pipeline programs. Developing a life-saving drug is a rare opportunity, and all of us at Omeros are energized and inspired by the patients – children and adults – who are alive today because of our team’s efforts.”

Third Quarter and Recent Developments

● Recent developments regarding narsoplimab, Omeros’ lead fully human monoclonal antibody targeting 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:

o In October, Professor Alessandro Rambaldi of the University of Milan and Papa Giovanni XXIII Hospital and Dr. Miguel Perales of Memorial Sloan Kettering Cancer Center presented the final efficacy and safety data from the pivotal trial of narsoplimab in the treatment of HSCT-TMA, which form the basis of the clinical sections of the rolling BLA.

◾ The complete response rates of 61 percent in patients receiving at least one dose of narsoplimab (the full analysis set) and 74 percent in patients receiving the protocol-specified narsoplimab treatment of at least four weeks (the per-protocol population) are higher than what was previously reported.

◾ Median overall survival was 274 days in the full analysis set, 361 days in the per-protocol population and could not be estimated for complete responders because more than half of the responders were still alive at last follow-up, out to as long as roughly four years following treatment.

o Omeros applied to the Centers for Disease Control and Prevention (CDC) for an International Classification of Diseases (ICD-10) diagnosis code for HSCT-TMA, and CDC has preliminarily indicated its support for the diagnosis code. Omeros also applied to CMS for an ICD-10 procedure code for the administration of narsoplimab, and CMS has indicated its support for issuance of the procedure code.

o In addition to the six COVID-19 patients who were treated with narsoplimab, Omeros has continued to treat critically ill COVID-19 patients under compassionate use. Omeros has also received requests and is in discussions to include narsoplimab in platform trials for COVID-19.

o Omeros’ discussions regarding the use of narsoplimab in COVID-19 have progressed with leadership across BARDA, NIAID, NCAT and NIH regarding narsoplimab for the treatment of critically ill COVID-19 patients. With COVID-19 surging again globally and other therapeutics having failed to show benefit in critically ill COVID-19 patients, there is increasing focus on narsoplimab.

● Recent developments regarding OMIDRIA include the following:

o Pass-through reimbursement status for OMIDRIA expired on October 1, 2020. Omeros met with CMS and the Department of Health and Human Services to assert that OMIDRIA meets the objective criteria specified by CMS and must be paid separately in the ambulatory surgery center (ASC) setting. Omeros also submitted to CMS a comment letter on the proposed 2021 Outpatient Prospective Payment System/ASC Rule along with a legal memorandum from an outside law firm reiterating this position and seeking confirmation of separate payment status for OMIDRIA in the ASC setting for the fourth quarter of 2020 and calendar year 2021.

o An article entitled “Real-world opioid prescribing after cataract surgery among patients who received intracameral phenylephrine and ketorolac 1.0%/0.3%” was published in the peer-reviewed journal Current Medical Research and Opinion. The study demonstrates that patients who received OMIDRIA during cataract surgery were prescribed fewer opioid pills following surgery than patients who did not

receive OMIDRIA, despite the OMIDRIA-treated group having a greater incidence of preoperative comorbidities and higher risk for surgical complexity.

● Updates regarding Omeros’ other development programs and platforms include the following:

o Omeros has completed, on schedule, dosing in the first cohort in a Phase 1, placebo-controlled, double-blind, single-ascending-dose and multiple-ascending-dose study for OMS906, the company’s MASP-3 inhibitor. The second cohort in the Phase 1 study has begun dosing. Omeros expects to achieve a once-monthly subcutaneous dosing regimen. Data readout from the Phase 1 study is planned for next year.

o Omeros presented data on the OMS906 program at the 4^th Complement-based Drug Development Summit in October.

Financial Results

For the third quarter of 2020, OMIDRIA revenues were $26.1 million, down from $29.9 million for the same period in 2019 and up from $13.5 million for the second quarter of 2020. The decrease compared to the third quarter of 2019 was due to an $8.7 million deduction as a reserve for product returns related to the expiration of pass-through reimbursement on October 1, 2020.

Total costs and expenses for the third quarter of 2020 were $51.5 million compared to $41.0 million for the same period in 2019. The increase reflects a fee payable under a technology license agreement related to Omeros’ MASP-3 program and increased pre-commercialization marketing activities for narsoplimab. Selling, general and administrative expenses were $19.8 million in the third quarter of 2020, compared to $16.9 million in the corresponding period in 2019. 

For the three months ended September 30, 2020, Omeros reported a net loss of $38.5 million, or $0.66 per share, compared to a net loss of $16.5 million, or $0.33 per share, for the same period in 2019. On a non-GAAP basis, adjusted net loss for the three months ended September 30, 2020 was $19.9 million, or $0.34 per share, after excluding non-cash expenses of $13.6 million, or $0.23 per share, and a technology access fee of $5.0 million, or $0.09 per share. Both net loss and adjusted net loss include the $8.7 million deduction in the third quarter of 2020 for the return reserve.

As of September 30, 2020, Omeros had $153.5 million of cash, cash equivalents and short-term investments available for operations and accounts receivable of $37.4 million.

During the third quarter, Omeros issued approximately $225.0 million aggregate principal amount 5.25% convertible senior notes due February 2026 (the 2026 Notes). Concurrently, Omeros repurchased $115.0 million aggregate principal amount of previously outstanding 6.25% convertible senior notes due November 2023. Omeros recorded a $13.4 million non-cash loss on early extinguishment of debt and a $7.9 million non-cash income tax benefit associated with these transactions. Omeros also entered into capped call contracts associated with the 2026 Notes that cover, subject to anti-dilution adjustments that may not match those applicable to the conversion price of the 2026 Notes, the number of shares of Omeros’ common stock underlying the 2026 Notes when Omeros’ common stock is trading between the initial conversion price of approximately $18.49 and the $26.10 cap price.

In August, Omeros sold 6.9 million shares in an underwritten public offering and received $93.7 million in net proceeds from the offering.

About Omeros Corporation

Omeros is a commercial-stage biopharmaceutical company committed to discovering, developing and commercializing small-molecule and protein therapeutics for large-market and orphan indications targeting inflammation, complement-mediated diseases, disorders of the central nervous system and immune-related diseases, including cancers. Its commercial product OMIDRIA (phenylephrine and ketorolac intraocular solution) 1%/0.3% continues to gain market share in cataract surgery. Omeros’ lead MASP-2 inhibitor narsoplimab targets the lectin pathway of complement and is the subject of a rolling biologics license application for hematopoietic stem cell transplant-associated thrombotic microangiopathy. Narsoplimab is also in multiple late-stage clinical development programs focused on other complement-mediated disorders, including IgA nephropathy, atypical hemolytic uremic syndrome and COVID-19. Omeros’ MASP-3

inhibitor OMS906, which targets the complement system’s alternative pathway, recently entered the clinic, and the company’s PDE7 inhibitor OMS527 has successfully completed Phase 1. Omeros’ pipeline holds a diverse group of preclinical programs including a novel antibody-generating technology and a proprietary GPCR platform through which it controls 54 new GPCR drug targets and their corresponding compounds. One of these novel targets, GPR174, modulates a new cancer immunity axis recently discovered by Omeros, and the company is advancing small-molecule GPR174 inhibitors.

The non-GAAP measures should be considered supplemental to, and not a substitute for or superior to, financial measures calculated in accordance with GAAP because non-GAAP financial measures used in this press release have limitations in that they do not reflect all costs associated with the operations of Omeros’ business. In addition, these measures may be different from, and therefore not comparable to, similarly titled measures used by other companies. The accompanying table provides more detail on the GAAP financial measures that are most directly comparable to the non-GAAP financial measures described above and the related reconciliations between these financial measures.
