About HMB-001

HMB-001 is bispecific antibody that binds and stabilizes endogenous factor VIIa (FVIIa) with one antibody arm and TLT-1 on activated platelets with the other arm. This allows for accumulation of FVIIa in the body, recruitment of FVIIa directly to the surface of the activated platelets where it is known to facilitate clotting, and avoidance of clotting activity in the absence of tissue damage. HMB-001 was designed to be a first-in-class prophylactic treatment for Glanzmann Thrombasthenia with potential for other debilitating rare bleeding disorders. It entered Phase 1/2 clinical evaluation in late 2022, with initial data expected 2H 2023.
