Biogen Idec Submits Application to FDA for First Long-Lasting Factor VIII Therapy for Hemophilia A

Tue, 03/12/2013 - 7:53am

Biogen Idec announced today that the company has submitted a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for the marketing approval of recombinant factor VIII Fc fusion protein (rFVIIIFc) for the treatment of hemophilia A. Recombinant FVIIIFc is the first hemophilia A product candidate in a new class of long-lasting clotting factor therapies being developed with the goal of reducing the burden of treatment for this condition. If approved, rFVIIIFc will be the first major advance in hemophilia A treatment in more than two decades. The regulatory submission was based on results from A-LONG, the largest registrational phase 3 clinical study in hemophilia A to date.

“This regulatory submission marks another significant step toward our goal of transforming the care of hemophilia for patients, families and caregivers,” said Glenn Pierce, M.D., Ph.D., senior vice president of Global Medical Affairs and chief medical officer of Biogen Idec’s hemophilia therapeutic area. “In our phase 3 study, patients treated with rFVIIIFc were able to inject rFVIIIFc once-weekly to twice-weekly, which creates the potential for those currently on prophylactic treatment to reduce injections by 50 to 100 per year. Moreover, patients currently treating bleeding episodes could potentially dose prophylactically once per week and maintain significant protection from bleeding with about the same total number of injections each year they use to treat bleeding episodes today.”

Typically, prophylaxis in hemophilia A requires injections three times per week or every other day to maintain a sufficient circulating level of clotting factor to provide protection from bleeding. Without prophylactic treatment, people with hemophilia A remain at risk of bleeding episodes that can cause irreversible joint damage and life threatening hemorrhages.

On March 4, 2013 Biogen Idec announced the FDA accepted for review the company’s BLA for its factor IX candidate, rFIXFc, for use in patients with hemophilia B.
