Welcome to our dedicated page for HEMAB THERAPEUTICS HOLDINGS news (Ticker: COAG), a resource for investors and traders seeking the latest updates and insights on HEMAB THERAPEUTICS HOLDINGS stock.
Hemab Therapeutics Holdings reports corporate and clinical-stage biotechnology developments tied to its blood coagulation disorder programs. Company news includes its Nasdaq listing and initial public offering, capital-structure updates, shareholder voting matters, and clinical or regulatory disclosures related to rare bleeding disorder therapeutics.
Updates for COAG also center on Hemab's development focus, including sutacimig (HMB-001), a bispecific antibody program for prophylactic treatment of Glanzmann thrombasthenia and Factor VII deficiency.
Hemab Therapeutics (Nasdaq: COAG) reported new clinical and preclinical data for sutacimig in Glanzmann thrombasthenia (GT) and Factor VII deficiency (FVIID) at the ISTH 2026 Congress. Phase 2 long-term extension (LTE) data in GT, covering 34 patients with a median 6.9 months and up to 15.9 months of exposure, showed sustained prophylactic bleed reduction and a manageable safety and tolerability profile. FDA has endorsed proceeding to a Phase 3 trial in 2H 2026 with a 0.2 mg/kg weekly regimen.
According to Hemab, 92% of participants who bled during run-in had reduced treated bleed rates on sutacimig, high‑intensity treated bleeds fell by 62%, and the low-dose weekly cohort saw about an 84% reduction in mean annualized treated bleeding rate. Three surgical or procedural cases achieved successful hemostasis. Adverse events were mostly mild or moderate, with three Grade 2 thromboembolic events in higher‑exposure or high‑risk cohorts, all managed with routine anticoagulation. Preclinical FVIID data showed restoration of thrombin generation and binding to most tested variants. Natural history studies (GT360, ATHN Transcends) documented lifelong weekly bleeding, high depressive symptom rates, and low prophylaxis use, reinforcing unmet need.
Hemab Therapeutics (Nasdaq: COAG) reported new first-in-human data for HMB-002 in Von Willebrand disease (VWD) and introduced HMB-003 for heavy menstrual bleeding at the ISTH 2026 Congress. HMB-002 showed dose-dependent ≥2.4-fold peak increases in Von Willebrand factor (VWF) and Factor VIII (FVIII), normalization of peak thrombin generation and activated partial thromboplastin time (APTT), and a pharmacokinetic/pharmacodynamic profile supporting potential monthly subcutaneous dosing.
According to Hemab, most treatment-emergent adverse events were mild or moderate, with no serious events, discontinuations, or thromboembolic, injection site, thrombocytopenia or hypersensitivity events. In the single ascending dose cohorts, 8 of 9 evaluable patients had zero treated bleeds over 28 days, versus a baseline mean annualized treated bleed rate of 20.1. Hemab also announced HMB-003, a non-hormonal, fatty-acid-conjugated peptide antifibrinolytic that directly inhibits plasmin, showed potent, selective antifibrinolytic activity and approximately one-week duration after a single subcutaneous dose in minipigs, supporting potential cycle-matched dosing in heavy menstrual bleeding.
Hemab Therapeutics (Nasdaq:COAG) will present nine clinical and preclinical updates from its coagulation pipeline at the ISTH 2026 Congress in Paris on July 11-15, 2026.
Highlights include Phase 2 LTE sutacimig data in GT, first-in-human HMB-002 results in VWD, and preclinical HMB-003 antifibrinolytic data.
Hemab Therapeutics (Nasdaq: COAG), a clinical-stage biotech focused on blood coagulation disorders, will participate in the 2026 Jefferies Global Healthcare Conference in New York.
A fireside chat is scheduled for Thursday, June 4, 2026 at 9:20 AM ET, with a live webcast and replay available on Hemab’s investor website.
