A Study Assessing HMB-002 in Participants With Von Willebrand Disease

This is a first-in-human (FIH), Phase 1/2, 3-part open-label, dose escalation, safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD), and efficacy study evaluating HMB-002 in participants with VWD. Part A of the study involves a single ascending dose (SAD) regimen design to establish safety, tolerability, PK, and PD effect. In Part B of the study, the safety and tolerability of repeat dosing will be established prior to cohort expansion to explore efficacy. Part C will evaluate the safety, PK, and PD of a single concomitant dose of HMB-002 and factor concentrate with Type 3 VWD or Type 1 VWD with low residual VWF and FVIII who use factor concentrate as prophylaxis.
