SEATTLE--(BUSINESS WIRE)-- Omeros Corporation (Nasdaq: OMER), a clinical-stage biopharmaceutical company committed to discovering, developing and commercializing small-molecule and protein therapeutics for large-market and orphan indications targeting immunologic disorders including complement-mediated diseases, cancers, and addictive and compulsive disorders, today announced recent highlights and developments as well as financial results for the fourth quarter and year ended December 31, 2022, which include:

• Net income in the fourth quarter of 2022 was $128.7 million, or $2.05 per share, compared to a net loss in the third quarter of 2022 of $17.5 million, or $0.28 per share; our fourth quarter’s net loss from continuing operations was $46.0 million, or $0.73 per share, compared to $54.8 million, or $0.87 per share, in the third quarter of 2022. Cash burn for the fourth quarter of 2022 was $26.0 million.
• For the year ended December 31, 2022, net income was $47.4 million, or $0.76 per share. This compares to net income of $194.2 million or $3.12 per share for the year ended December 31, 2021.
• The milestone event specified in the asset purchase agreement by which we sold our former ophthalmology product OMIDRIA^® to Rayner Surgical, Inc. (“Rayner”) occurred in December 2022, resulting in us recording as a receivable the $200.0 million milestone payment from Rayner in December 2022 and receiving the cash payment in February 2023.
• For the fourth quarter ended December 31, 2022, we earned OMIDRIA royalties of $17.9 million on Rayner’s U.S. net sales of $35.8 million, an all-time high for quarterly net sales of OMIDRIA. This compares to earned royalties of $16.5 million during the third quarter of 2022. For the year ended December 31, 2022, we earned royalties of $65.4 million on U.S. net sales of OMIDRIA.
• At December 31, 2022, we had $194.9 million of cash, cash equivalents and short-term investments. In addition, we had $213.2 million of accounts receivable, substantially all of which have been collected. We do not have any assets on deposit with Silicon Valley Bank nor do we have any other financial relationship with the bank or its affiliated entities.
• The Consolidated Appropriations Act of 2023 (“CAA”) was signed into law in late December 2022 and expressly provides for separate payment of non-opioid pain management drugs, like OMIDRIA, in the outpatient surgery setting until January 1, 2028.
• We are preparing to resubmit our Biologics License Application (“BLA”) for narsoplimab in hematopoietic stem cell transplant-associated thrombotic microangiopathy (“TA-TMA”) and have requested a meeting with FDA, expected to be held next quarter, to confirm the additional information required by FDA to support approval.
• We have initiated two clinical trials evaluating OMS906, one enrolling patients with paroxysmal nocturnal hemoglobinuria (“PNH”) who are treatment-naïve and the other enrolling PNH patients who have demonstrated an unsatisfactory response to ravulizumab; dosing is ongoing in the first and initiating in the second.

“With over $400 million available for operations and having secured our ongoing OMIDRIA royalty stream, Omeros now has the flexibility to retire our 2023 debt obligation while funding accelerated advancement across our portfolio of cutting-edge platforms and programs well into 2025. Any additional revenue source – for which there are multiple opportunities – would only extend that runway, further driving shareholder value without the need for dilution,” said Gregory A. Demopulos, M.D., Omeros’ chairman and chief executive officer. “For narsoplimab, we are meeting with FDA to confirm the information required for approval of our resubmitted BLA for TA-TMA, we remain on track for third-quarter release of topline data from our pivotal ARTEMIS-IGAN trial, and there is mutual interest in working with the U.S. government in COVID-19 and ARDS. Our long-acting MASP-2 inhibitor OMS1029 looks promising in the clinic for quarterly IV or SC administration and, together with our orally available small-molecule inhibitors, complements narsoplimab and expands our control over the lectin pathway. OMS906, targeting the key activator of the alternative pathway MASP-3, we expect can also be dosed once quarterly and, given its significant biological advantages over potential competitors, pending efficacy data in PNH followed by C3G will go a long way in answering whether MASP-3 and OMS906 are the premier alternative-pathway target and therapeutic. We also are hoping for good news over the coming weeks on our PDE7 inhibitor OMS527 in both addiction and in Parkinson’s disease. And our novel molecular and cellular immuno-oncology platforms and programs continue to generate exciting data that consistently point to the same conclusion – the potential for transformative cancer therapies. All of our portfolio programs could well be successful, but the success of any one of them would deliver substantial shareholder value.”

Fourth Quarter and Recent Clinical Developments

• Recent developments regarding narsoplimab, our lead monoclonal antibody targeting mannan-binding lectin-associated serine protease-2 (“MASP-2”) in advanced clinical programs for the treatment of TA-TMA and immunoglobulin A (“IgA”) nephropathy, include:
  • Preparations are underway for anticipated resubmission of our BLA for narsoplimab in TA-TMA following the late-2022 receipt of the decision by FDA’s Office of New Drugs regarding our appeal of FDA’s complete response letter previously issued on our original BLA. The decision denying our appeal proposed, as a path forward for BLA resubmission, the inclusion of additional analyses comparing response and survival in our completed pivotal trial to appropriate historical controls. We have requested a meeting with FDA’s Division of Nonmalignant Hematology to confirm the information required by FDA to support approval of narsoplimab in this indication. We expect that the Type B meeting will occur in the first half of the second quarter of 2023.
  • Our Phase 3 ARTEMIS-IGAN trial evaluating narsoplimab for the treatment of IgA nephropathy continues to progress toward an anticipated readout of 9-month data on the proteinuria endpoint in the third quarter of 2023.
  • An international group of leading transplanters recently published a systematic review of signs and symptoms of TA-TMA in Transplantation and Cellular Therapy, and a second manuscript on TA-TMA diagnosis and treatment has been accepted for publication by Bone Marrow Transplantation.
• Recent developments regarding OMS1029, our long-acting, next-generation MASP-2 inhibitor, include:
  • Dosing of all cohorts in a single-ascending dose Phase 1 clinical trial of OMS1029 was successfully completed in early 2023. OMS1029 was well tolerated with no safety concerns identified. Preliminary pharmacokinetic (“PK”) and pharmacodynamic (“PD”) data show dose-proportional exposure and sustained lectin pathway inhibition, consistent with potentially quarterly intravenous or subcutaneous dosing.
  • Preparations are underway to initiate, in summer 2023, a Phase 1 multiple-ascending-dose study of OMS1029 in healthy subjects.
• Recent developments regarding OMS906, our lead monoclonal antibody targeting mannan-binding lectin-associated serine protease-3 (“MASP-3”), the key activator of the alternative pathway, include:
  • Clinical data from our single-ascending-dose Phase 1 study evaluating both intravenous and subcutaneous administration of OMS906 in healthy subjects were presented in December at the annual meeting of the American Society of Hematology. As previously announced, the drug was well tolerated, and there were no safety signals of concern. Based on clinical data to date, we expect that OMS906 will be dosed quarterly, either intravenously or subcutaneously.
  • In late 2022 we began enrolling in our Phase 1b clinical trial evaluating OMS906 in treatment-naïve patients with PNH. Dosing in this study began in early 2023.
  • Enrollment has also begun in our Phase 1b clinical trial evaluating OMS906 in PNH patients who have had an unsatisfactory response to the C5 inhibitor ravulizumab. The study enrolls PNH patients receiving ravulizumab, adds OMS906 to provide combination therapy with ravulizumab for 24 weeks, and then provides OMS906 monotherapy in patients who demonstrate a hemoglobin response with combination therapy. First dosing of OMS906 in this study is scheduled to begin later this month, once the ravulizumab monotherapy period has ended.
  • A Phase 1b clinical trial evaluating OMS906 in patients with complement 3 glomerulopathy (“C3G”) has also been initiated, with enrollment expected to commence next month.
• Recent developments regarding OMS527, our phosphodiesterase 7 (“PDE7”) inhibitor program focused on addiction and movement disorders, include:
  • We are engaged in discussions with third parties regarding external funding for development of our PDE7 inhibitors as a treatment for addictive disorders.
  • OMS527 is also being evaluated as a potential treatment for levodopa-induced dyskinesias (“LID”), which are crippling, involuntary movements reportedly affecting 50 percent or more of levodopa-treated patients with Parkinson’s disease. LID is caused by prolonged treatment with levodopa, the most prescribed treatment for Parkinson’s. Collaborators at Emory University are evaluating our PDE7 inhibitor in a clinically predictive primate model of LID.

Financial Results

Net income for the fourth quarter of 2022 was $128.7 million, or $2.05 per share, which includes the $200.0 million milestone recognized as income in discontinued operations. This compares to a net loss of $17.5 million in the third quarter of 2022, or $0.28 per share. Net loss from continuing operations for the fourth quarter of 2022 was $46.0 million, or $0.73 cents per share. For the third quarter of 2022, net loss from continuing operations was $54.8 million, or $0.87 per share. Cash burn for the fourth quarter of 2022 was $26.0 million.

Net income for the full year 2022 was $47.4 million, or $0.76 per share, and our net loss from continuing operations was $182.0 million or $2.90 per share. This compares to the prior full year’s net income of $194.2 million, or $3.12 per share, and a loss from continuing operations of $191.5, or $3.07 per share.

In December 2022, the milestone event entitling us to a $200.0 million milestone payment from Rayner occurred. We recorded the $200.0 million milestone as revenue in discontinued operations and as a receivable in December 2022. We received the cash payment on February 3, 2023. Per the terms of the asset purchase agreement with Rayner, following the milestone event the applicable royalty rate was reduced to 30% of the net revenue from U.S. sales of OMIDRIA. Upon achieving the $200.0 million milestone, we conservatively revalued the OMIDRIA contract royalty asset using the reduced royalty rate of 30% on future OMIDRIA U.S. net sales while reflecting an increase in expected OMIDRIA U.S. net sales due to the CAA securing separate payment for drugs like OMIDRIA until at least January 1, 2028. This remeasurement resulted in a $26.2 million reduction in the OMIDRIA contract royalty asset and a corresponding loss being recorded in discontinued operations in the fourth quarter.

During the fourth quarter of 2022, we earned royalties of $17.9 million on $35.8 million of Rayner sales of OMIDRIA. This compares to earned royalties of $16.5 million in the third quarter of 2022. These royalties were recorded as a reduction of the OMIDRIA contract royalty asset.

Total costs and expenses for the fourth quarter of 2022 were $40.1 million compared to $50.8 million for the third quarter of 2022. The decrease was primarily due to the manufacturing of narsoplimab drug substance in the third quarter of 2022 for future commercial and clinical use. We expense commercial drug substance until approval is assured.

Interest expense during the fourth quarter of 2022 was $7.9 million, an increase of $3.0 million from the third quarter of 2022. On September 30, 2022, we sold to DRI Healthcare Acquisitions LP an interest in a portion of our future OMIDRIA royalty receivables and received $125.0 million in cash proceeds. The transaction was recorded as debt for financial reporting purposes with an implied interest rate of 9.4%.

Net income from discontinued operations, net of tax was $174.8 million, or $2.78 per share, in the fourth quarter of 2022 compared to net income from discontinued operations, net of tax of $37.3 million, or $0.59 per share, in the prior quarter. The increase was primarily due to the $200.0 milestone we earned in the fourth quarter, partially offset by the milestone-driven revaluation of the OMIDRIA contract royalty asset.

As of December 31, 2022, we had $194.9 million of cash, cash equivalents and short-term investments. In addition, we had $213.2 million in accounts receivable, all of which have now been collected. We previously maintained a line of credit with Silicon Valley Bank, which we allowed to expire in August 2022. We do not have any assets on deposit with Silicon Valley Bank nor do we have any other financial relationship with the bank or its affiliated entities
