Abstract

Prophylaxis for hemophilia A with conventional factor VIII (FVIII) products requires frequent intravenous dosing, which may reduce adherence. Recombinant factor VIII Fc fusion protein (rFVIIIFc) has a prolonged half-life compared with conventional rFVIII, and has demonstrated safety and efficacy for the prevention and treatment of bleeding episodes in phase 3 studies of patients with severe hemophilia A. Most subjects experienced reduced prophylactic dosing frequency with rFVIIIFc compared with prestudy FVIII; the median total weekly prophylactic consumption was comparable. No subjects developed inhibitors. These results suggest that prophylaxis with rFVIIIFc in patients with hemophilia A may allow less frequent prophylactic dosing while maintaining efficacy, with comparable prophylactic consumption.
