Biogen Idec and Sobi Announce Positive Top-Line Results from Phase 3 Study

Biogen Idec BIIB and Swedish Orphan Biovitrum (Sobi) SOBI today 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 (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.
