Omeros (NASDAQ: OMER) has announced two upcoming presentations at the 2025 Tandem Meetings in Honolulu, Hawaii, focusing on narsoplimab treatment outcomes for TA-TMA patients under an expanded access program. The first presentation, by Dr. Michelle Schoettler from Emory University School of Medicine, will discuss overall survival rates among 128 allogeneic transplant patients treated with narsoplimab.

The second presentation, by Dr. Piyatida Chumnumsiriwath from UC Irvine, will showcase findings from a single-center study of adult TA-TMA patients who received narsoplimab after unsuccessful eculizumab treatment.

Omeros (NASDAQ: OMER) announced positive statistical sensitivity analysis results for narsoplimab in treating transplant-associated thrombotic microangiopathy (TA-TMA). The analyses validate previously reported primary endpoint results showing 2-fold to 4-fold reduction in mortality risk (hazard ratios 0.24-0.42) with p-values ranging from 0.0124 to <0.00001.

The primary endpoint analysis demonstrated an over 3-fold reduction in mortality risk (hazard ratio = 0.32) in narsoplimab-treated patients compared to external control. The company plans to resubmit its Biologics License Application (BLA) to FDA this quarter and targets Marketing Authorization Application (MAA) submission to European regulators by mid-year. Narsoplimab aims to become the first approved treatment for TA-TMA, a life-threatening complication in stem cell transplantation.

Omeros (OMER) announced successful results from its narsoplimab pivotal trial for treating transplant-associated thrombotic microangiopathy (TA-TMA). The primary statistical analysis showed that patients treated with narsoplimab had an over 3-fold reduction in mortality risk (hazard ratio = 0.32) compared to untreated patients in an external control group.

The study compared 28 narsoplimab-treated TA-TMA patients against more than 100 similar high-risk patients from a stem cell transplant registry. The results were highly statistically significant (p < 0.00001). Based on these positive outcomes, Omeros will resubmit its Biologics License Application (BLA) to FDA, aiming to make narsoplimab the first approved treatment for TA-TMA.

Omeros (OMER) presented two posters about zaltenibart (OMS906), their investigational MASP-3 inhibitor, at the ASH Annual Meeting. The presentations focused on Phase 2 clinical data and clinical pharmacology analyses for treating paroxysmal nocturnal hemoglobinuria (PNH).

The Phase 2 'switch-over' study showed that zaltenibart monotherapy achieved sustained improvements in hemoglobin and absolute reticulocyte count in PNH patients who had inadequate response to ravulizumab. The treatment was well-tolerated with no concerning safety signals.

Pharmacokinetic/pharmacodynamic modeling identified 8mg/kg as the optimal intravenous dose administered every 8 weeks, achieving >98% suppression of alternative pathway activation. Phase 3 clinical trials are expected to begin enrollment in early 2025.

Omeros (NASDAQ: OMER) has announced two upcoming presentations about zaltenibart (OMS906), their investigational MASP-3 inhibitor, at the 66th Annual Meeting of the American Society of Hematology (ASH) in San Diego, December 7-10, 2024. The presentations focus on treating paroxysmal nocturnal hemoglobinuria (PNH), a rare blood disorder.

The presentations include interim results from a Phase 2 proof-of-concept study showing improved hematologic parameters in PNH patients, and a pharmacokinetics/pharmacodynamics study. Phase 3 clinical trials for zaltenibart in PNH are scheduled to begin in early 2025.

Omeros (Nasdaq: OMER) has provided an update on its progress toward resubmitting its biologics license application (BLA) for narsoplimab in hematopoietic stem cell transplant-associated thrombotic microangiopathy (TA-TMA). The company has received FDA's response on the revised statistical analysis plan (SAP) and has no other presubmission requests pending. An independent expert statistical group will conduct data analyses, and if results support resubmission, the company plans to finalize and resubmit the BLA promptly. The FDA's recent feedback included recommendations for additional sensitivity analyses, which Omeros has accepted.
