-New Phase 3 Data Support Potential Efficacy, Safety and Pharmacokinetics of Long-Lasting Factor Product Candidates-
-Ten Oral Presentations Highlight Clinical Data and New Early-Stage Research from Hemophilia Development Program-

CAMBRIDGE, MA, USA I June 24, 2013 I Biogen Idec (BIIB) will showcase new data from a number of development and early-stage research programs at the XXIV International Society on Thrombosis and Haemostasis (ISTH) Congress. Researchers will present 33 abstracts on clinical and pre-clinical research in hemophilia, the breadth of which reflects the company’s commitment to innovation and the scientific advancement of hemophilia treatment and care. The ISTH Congress will be held June 29 through July 4 in Amsterdam, The Netherlands. 

 “There are significant unmet needs in hemophilia A and B, rare chronic diseases that have a tremendous impact on the lives of patients and their families,” said Glenn Piece, M.D., Ph.D., senior vice president, Global Medical Affairs and chief medical officer at Biogen Idec. “The robust research being showcased at ISTH reflects our commitment to the community to address these unmet needs through innovative research and science. This includes striving to bring the first major advances in hemophilia treatment in more than fifteen years.” 

 Biogen Idec and Swedish Orphan Biovitrum (Sobi) will present new analyses of the phase 3 A-LONG study of ELOCTATE* and B-LONG study of ALPROLIX**, results of which add to the growing body of evidence supporting the potential efficacy and safety of these long-lasting clotting factor candidates for the treatment of hemophilia A and B. 

 The company will also share pre-clinical findings from new factor VIII molecules that achieved a circulating half-life of 30 hours in mice, representing a four-fold improvement over factor VIII. Additionally, new data will be presented from the company’s long-lasting factor VIIa program targeting development of a potential new option for patients with hemophilia who have inhibitory antibodies that make factor replacement ineffective.

ELOCTATE and ALPROLIX Global Regulatory Status

 Biologics License Applications (BLAs) for Biogen Idec’s long-lasting hemophilia product candidates ELOCTATE and ALPROLIX are currently under review with the U.S. Food and Drug Administration (FDA) for the treatment of hemophilia A and B, respectively. 

Marketing Applications for ELOCTATE and ALPROLIX have been submitted in Australia for the treatment of hemophilia A and B, respectively. A Marketing Application for ALPROLIX has been submitted in Canada for the treatment of hemophilia B. Additional global filings are planned.

About the Fc Fusion Technology Platform

 ELOCTATE and ALPROLIX are clotting factors under development using Biogen Idec’s novel and proprietary monomeric Fc fusion technology, which makes use of a naturally occurring pathway that delays the breakdown of factor in the body and cycles it back into the bloodstream, resulting in a longer circulating half-life. Fc fusion technology is used in seven FDA-approved products for the treatment of chronic diseases including rheumatoid arthritis, psoriasis and platelet disorders. 

About Hemophilia A

 Hemophilia A is a rare, inherited disorder in which the ability of a person’s blood to clot is impaired. Hemophilia A occurs in about one in 5,000 male births annually and is caused by having substantially reduced or no factor VIII activity, which is needed for normal blood clotting. People with hemophilia A experience bleeding episodes that can cause pain, irreversible joint damage and life-threatening hemorrhage. Injections of factor VIII can restore the coagulation process, control bleeding, and prevent new bleeding episodes. The Medical and Scientific Advisory Council of the National Hemophilia Foundation recommends prophylaxis as the optimal therapy for people with severe hemophilia A. Currently, prophylaxis in hemophilia A typically requires injections every two to three days to maintain a sufficient circulating level of clotting factor

About Hemophilia B

 Hemophilia B is a rare, inherited disorder in which the ability of a person’s blood to clot is impaired. Hemophilia B occurs in about one in 25,000 male births annually and is caused by having substantially reduced or no factor IX activity, which is needed for normal blood clotting. People with hemophilia B experience bleeding episodes that can cause pain, irreversible joint damage and life-threatening hemorrhage. Injections of factor IX can restore the coagulation process, control bleeding, and prevent new bleeding episodes. The Medical and Scientific Advisory Council of the National Hemophilia Foundation recommends prophylaxis as the optimal therapy for people with severe hemophilia B. According to the World Federation of Hemophilia, prophylaxis in hemophilia B typically requires injections up to three times per week to maintain a sufficient circulating level of clotting factor.
