Emicizumab for Severe Von Willebrand Disease (VWD) and VWD/Hemophilia A

Summary

Von Willebrand Disease (VWD) is the most common inherited bleeding disorder affecting up to 0.1% of the population, is usually characterized by mucocutaneous bleeding, HMB, surgical bleeding or other hemostatic challenges. Severe bleeding events require VWF concentrates administered solely through intravenous access. Emicizumab (Hemlibra) is a monoclonal bispecific antibody developed to bind activated FIX and FX and mimic FVIII cofactor functionality. Hemlibra is administered via subcutaneous injection rather than intravenous infusion. The hypothesis of this study is that Emicizumab is safe and efficacious for prophylaxis in severe VWD and concomitant VWD/hemophilia patients.
