KING OF PRUSSIA, Pa., May 26, 2016 — CSL Behring announced today that the U.S. Food and Drug Administration (FDA) has approved AFSTYLA [Antihemophilic Factor (Recombinant), Single Chain], its novel long-lasting recombinant factor VIII single-chain therapy for adults and children with hemophilia A. AFSTYLA is the first and only single-chain product for hemophilia A that is specifically designed for long-lasting protection from bleeds with two to three times weekly dosing. In clinical trials, patients undergoing prophylaxis with AFSTYLA experienced a median annualized spontaneous bleeding rate (AsBR) of 0.00. Once activated, AFSTYLA is identical to natural factor VIII. Clinical trials of AFSTYLA demonstrated a strong safety profile with no inhibitors observed.
AFSTYLA is indicated in adults and children with hemophilia A for routine prophylaxis to reduce the frequency of bleeding episodes; on-demand treatment and control of bleeding episodes; and the perioperative management of bleeding. AFSTYLA is expected to be available early this summer.
