● Net loss for the second quarter of 2024 was $56.0 million, or $0.97 per share, compared to a net loss of $37.3 million, or $0.59 per share for the second quarter of 2023. For the six months ended June 30, 2024, our net loss was $93.2 million, or $1.60 per share, compared to a net loss of $71.0 million, or $1.13 per share in the prior year period. The second quarter of 2024 includes a $17.6 million charge for narsoplimab drug substance delivered during the quarter, the manufacturing of which commenced in October 2023, a $21.2 million payment for term loan-related debt repurchase, and $1.9 million of term loan-related transaction costs. These significant cash outlays, representing a total of $40.7 million dollars, are not expected to be repeated in the foreseeable future.
● On June 3, 2024, we entered into a Credit and Guaranty Agreement (the "Credit Agreement") with funds managed by Athyrium Capital Management (collectively, "Athyrium") and funds managed by Highbridge Capital Management (collectively, "Highbridge") as lenders (the "Lenders"). Under the Credit Agreement, we entered into an initial senior secured term loan of $67.1 million (the "Initial Term Loan") and paid $21.2 million to the Lenders in exchange for $118.1 million aggregate principal amount of Omeros’ existing 5.25 percent convertible senior notes due on February 15, 2026 (the "2026 Notes") held by the Lenders and representing 55 percent of our total 2026 Notes. The Credit Agreement also provides for a $25.0 million delayed draw term loan available to be drawn on request by Omeros on or prior to June 3, 2025 contingent on regulatory approval of narsoplimab in hematopoietic stem cell transplant-associated thrombotic microangiopathy ("TA-TMA"). All loans under the Credit Agreement have a stated maturity date of June 3, 2028.
ο The purchase price in the debt exchange and repurchase of our outstanding 2026 Notes represents a discount from notional value of approximately 25 percent.
ο Neither the Initial Term Loan nor the delayed draw term loan includes equity consideration for the Lenders, preventing any shareholder dilution as a consequence of these transactions.
ο After giving effect to the repurchase, we had approximately $98 million principal amount of our 2026 Notes outstanding.
● At June 30, 2024, we had $158.9 million of cash and short-term investments available for operations and debt servicing, a decrease of $12.9 million from December 31, 2023.
● As previously disclosed, we submitted an analysis plan to assess our existing clinical trial data along with other evidence proposed to be included in a resubmission of our biologics license application ("BLA") for narsoplimab in TA-TMA. We are engaged in ongoing discussions with the FDA regarding the analysis plan and the other evidence proposed to be included in the submission. An additional meeting with FDA has been scheduled and we expect to provide a further update on our plans for resubmission and anticipated timing when more definitive information becomes available.
● We continued advancing our lead MASP-3 inhibitor antibody zaltenibart (also known as OMS906) through a Phase 2 development program in paroxysmal nocturnal hemoglobinuria ("PNH") comprised of two fully enrolled clinical trials and a long-term extension study in which patients who have completed either of the first two studies are eligible to enroll. Patients continue to accrue to the extension study and we remain on track to initiate our Phase 3 program for zaltenibart in PNH later this year.
● Enrollment is ongoing in our Phase 2 clinical trial evaluating zaltenibart for the treatment of complement 3 glomerulopathy ("C3G"). A Phase 3 program in C3G is planned to begin in early 2025.
"Throughout the second quarter, we continued rapidly progressing our clinical programs while significantly strengthening our balance sheet," said Gregory A. Demopulos, M.D., Omeros’ chairman and chief executive officer. "Through the term loan and note repurchase transaction completed in June, we reduced by more than half the outstanding balance of our 2026 convertible notes at a substantial discount to par value without diluting shareholders. With the new secured term loan in place, a substantial portion of our outstanding debt is now maturing in 2028, the Company is well positioned to address the remaining balance of our 2026 convertible notes, and we have access to an additional term loan of up to $25 million to fund the commercial launch of narsoplimab in TA-TMA. Although the lengthy regulatory process is a continuing source of frustration for our team, our shareholders and, most especially, the TA-TMA patients in need of an effective treatment for this often-lethal condition, we believe that the evidence we have proposed to submit with our BLA is highly compelling and we remain dedicated to making narsoplimab the first approved product for the treatment of TA-TMA. We look forward to providing a further update on the outcome of our ongoing discussions with FDA. In parallel, our MASP-3 inhibitor zaltenibart continues to advance rapidly, generating consistently – and compared to other marketed and developing alternative pathway inhibitors – strong data, and it remains on track to initiate a Phase 3 program in PNH later this year and, in C3G, early in 2025."
Second Quarter and Recent Clinical Developments
● Recent developments regarding narsoplimab, our lead monoclonal antibody targeting mannan-binding lectin-associated serine protease-2 ("MASP-2"), include the following:
o We previously submitted to FDA an analysis plan to assess already existing clinical trial data, existing data from an historical control population available from an external source, data from the narsoplimab expanded access (i.e., compassionate use) program, and data directed to the mechanism of action of narsoplimab. We are having ongoing discussions with the agency regarding the proposed analysis plan and FDA’s requirements for our resubmission of our BLA. An additional meeting with FDA has been scheduled and we expect to provide a further update on our plans for resubmission and the anticipated timing when more definitive information becomes available.
o FDA recently announced the establishment of the Rare Disease Innovation Hub, which will serve as a single point of connection and engagement within the FDA to support the development of treatments and products for rare diseases. The hub will have a particular focus on products intended for smaller populations or for diseases where the natural history is variable and not fully understood. FDA’s focus on these issues and their responsiveness to the rare disease community’s advocacy is encouraging, and we view the establishment of the hub as a tangible demonstration of FDA’s commitment to recognizing and addressing the unique challenges faced in developing therapies for these conditions.
ο In addition to previous publications on narsoplimab in TA-TMA, international transplant experts are preparing two manuscripts – one directed to the results of a survival comparison between our pivotal trial of narsoplimab in TA-TMA and an external control population of TA-TMA patients and the second detailing the survival data obtained from narsoplimab treatment of TA-TMA patients in our expanded access program. Physicians continue to request access to narsoplimab under this program for their patients with TA-TMA. Given that there is no approved treatment for this life-threatening condition, we continue to do what we can to help these patients.
● Recent developments regarding OMS1029, our long-acting, next-generation MASP-2 inhibitor, include:
o Both the single- and multiple-ascending-dose Phase 1 studies of OMS1029 have now been completed. The results support once-quarterly dosing, administered either subcutaneously or intravenously. Data from the multiple-ascending-dose study will be utilized to inform dose selection for continued clinical development. Consistent with the results of the single-ascending-dose Phase 1 clinical trial of OMS1029 completed in early 2023, OMS1029 was generally well tolerated at all doses evaluated in the multiple-ascending-dose study, with no significant safety concern identified to date.
o We continue to evaluate large market indications for Phase 2 clinical development of OMS1029. These include neovascular age-related macular degeneration, sometimes referred to as "wet AMD." MASP-2 inhibition previously showed efficacy in a pre-clinical murine model of wet AMD and we are currently engaged in a primate study comparing OMS1029 to Eylea (afibercept), a product currently approved to treat wet AMD. If shown to be effective, OMS1029 administered systemically (e.g., either intravenously or subcutaneously) could represent a significantly more attractive treatment experience compared to Eylea and other currently approved treatments for wet AMD, which require frequent injections directly into the posterior chamber of the eye.
● 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:
o The United States Adopted Names Council ("USAN"), in consultation with the World Health Organization’s International Nonproprietary Names Expert Committee ("INN"), recently selected the nonproprietary name "zaltenibart" for OMS906. The USAN Council, by working closely with the INN Programme of the World Health Organization and various national nomenclature groups, aims for global standardization and unification of drug nomenclature to ensure that drug information is communicated accurately and unambiguously. Going forward, we will use the name zaltenibart to refer to our lead MASP-3 antibody in publications, at conferences and across other forums.
o Our Phase 2 trial evaluating two doses of zaltenibart in PNH patients who have had an unsatisfactory response to the C5 inhibitor ravulizumab has continued to produce encouraging data. The study utilizes a "switch-over" design, enrolling PNH patients who are receiving ravulizumab and adding zaltenibart to provide combination therapy with ravulizumab for 24 weeks. Those patients who demonstrate a hemoglobin response with the combination therapy are then switched to zaltenibart monotherapy. In June, at the annual congress of the European Hematology Association (EHA) (Free EHA Whitepaper), interim analysis results from the combination therapy portion of the trial were presented by Dr. Morag Griffin, an internationally recognized PNH expert from St. James University Hospital in England. During the adjunctive therapy period, the statistically significant mean hemoglobin improvement from baseline was 3.27 g/dL and 10 of 12 patients advanced to monotherapy. Absolute reticulocyte count also demonstrated statistically significant improvement. Zaltenibart was safe and well tolerated. An abstract providing results of the zaltenibart monotherapy stage has been submitted to the American Society of Hematology (ASH) (Free ASH Whitepaper) for presentation at their annual meeting in December. The efficacy and safety profiles of zaltenibart as monotherapy remain strong, including demonstration of sustained and clinically meaningful improvements in hemoglobin levels and absolute reticulocyte counts, as well as prevention of both extravascular and intravascular hemolysis.
o Our Phase 2 study of zaltenibart in PNH patients who have not previously received treatment with a complement inhibitor (i.e., naïve patients) is also ongoing and continues to progress well. Results from an interim analysis of subcutaneous zaltenibart treatment were presented at the American Society of Hematology (ASH) (Free ASH Whitepaper) meeting held in December 2023. Following that presentation, we amended the study protocol to identify the plasma concentrations and the level of MASP-3 inhibition required to inhibit breakthrough hemolysis. These data, in combination with data derived from our "switch-over" PNH study and from our Phase 1 studies in healthy subjects, are expected to provide all the data needed to finalize selection of the zaltenibart dose for our upcoming Phase 3 clinical trials.
o We plan to conduct two trials in our Phase 3 program for zaltenibart in PNH. Similar to our Phase 2 program, one will enroll complement inhibitor-naïve patients and the other will employ a "switch over" design. Through our recent advisory boards with experts in PNH and focus-group PNH patients, we have received valuable input to inform the design of our Phase 3 studies and our positioning of zaltenibart in the marketplace, if approved. The zaltenibart drug substance necessary to supply our Phase 3 clinical trials has been manufactured, upcoming pre-Phase 3 meetings with both European and U.S. regulators have been scheduled or requested, and the other activities required to initiate our Phase 3 program have also been completed or are progressing as planned. We remain on track to initiate the program later this year.
● Recent developments regarding OMS527, our phosphodiesterase 7 ("PDE7") inhibitor program focused on addictions and compulsive disorders as well as movement disorders, include:
o In April 2023 we were awarded a three-year, $6.69 million grant by the National Institute on Drug Abuse ("NIDA") to pursue development of our lead orally administered PDE7 inhibitor compound for the treatment of cocaine use disorder ("CUD"). We expect to complete by the end of this year a grant-funded preclinical cocaine interaction study, which is a safety prerequisite to initiation of the randomized, placebo-controlled, inpatient clinical study evaluating the safety and effectiveness of OMS527 in patients with CUD, which is also contemplated to be funded with proceeds of the NIDA award.
