Biogen and Sobi announce positive results from Phase 3 study rFVIIIFc

Biogen Idec and Swedish Orphan Biovitrum, or Sobi, announced positive results from A-LONG, a clinical study that evaluated a new long-lasting clotting factor candidate in people with hemophilia A. Hemophilia A is a rare inherited disorder that impairs blood coagulation. Top-line results from A-LONG, a global, multi-center, Phase 3 clinical study of the companies' long-lasting recombinant Factor VIII Fc fusion protein, or rFVIIIFc, showed that rFVIIIFc was effective in the control and prevention of bleeding, routine prophylaxis and perioperative management. Recombinant FVIIIFc was generally well-tolerated. Additional analyses of the A-LONG study are ongoing, and the companies anticipate presenting detailed results at a future scientific meeting.
