Baxter Submits Application for FDA Approval of Recombinant Factor IX for the Treatment of Hemophilia B

DEERFIELD, Ill. - Baxter International Inc. (NYSE:BAX) today announced that the company has submitted a biologics license application (BLA) to the United States (U.S.) Food and Drug Administration (FDA) for approval of BAX 326, a recombinant factor IX (rFIX) protein being investigated for the treatment and prophylaxis of bleeding episodes for patients over 12 years of age with hemophilia B.
Hemophilia B, also known as Christmas disease, is the second most common type of hemophilia and results from insufficient amounts of clotting factor IX, a naturally occurring protein in blood that helps to control bleeding. 1 Approximately 25,000 people worldwide, including more than 4,000 in the U.S., have been diagnosed with hemophilia B. 2
The BLA filing is based on results from a global Phase III study conducted in 10 countries around the world. The prospective, controlled, multicenter study evaluated the pharmacokinetics, efficacy, safety and immunogenicity of BAX 326 in 73 patients with severe or moderately severe hemophilia B previously treated with other factor IX therapy. The study met its primary objectives and the company plans to present the complete data from the study in late 2012. Baxter expects to file its application for BAX 326 in Europe in 2013.
"Hemophilia B patients have relatively limited options for their treatment today, with only one commercially available recombinant (genetically engineered) protein. As part of our long-standing commitment to the hemophilia community, we continue to pursue new potential treatment options like BAX 326 to support patients with this debilitating disease," said Prof. Hartmut J. Ehrlich, M.D., vice president of global research and development in Baxter's BioScience business.
In select countries, Baxter currently offers a plasma-derived factor IX treatment, Immunine [Factor IX Concentrate (Human)], for patients with hemophilia B, which has more than 16 years of patient experience in Europe and Latin America. In addition, Baxter recently announced a partnership with Chatham Therapeutics, LLC to develop a gene therapy based treatment for hemophilia B. Gene therapy could represent another important first for the community as an innovative potential therapy for hemophilia B treatment.
