Biogen Idec to acquire Syntonix Pharma

Cambridge, MassachusettsSaturday, January 6, 2007, 08:00 Hrs  [IST]

Biogen Idec and Syntonix Pharmaceuticals announced that the companies have signed a definitive agreement for the acquisition of Syntonix by Biogen Idec. Syntonix, a privately held biopharmaceutical company focused on discovering and developing long-acting therapeutic products to improve treatment regimens for chronic diseases, has multiple pre-clinical programmes in haemophilia. Syntonix uses proprietary technologies to harness the human body's natural pathways for protecting antibodies against premature destruction and for transporting antibodies across cell barriers such as those in the lungs. These technologies may enhance the delivery of biopharmaceuticals through less frequent injections or by enabling pulmonary delivery. Syntonix's lead product, FIX:Fc, is a proprietary long-acting factor IX product for the treatment of haemophilia B. It has the potential to reduce the frequency of intravenous injections required for disease management. Syntonix is expected to file an investigational new drug application with the Food and Drug Administration for FIX:Fc in 2007. "With this transaction, we continue to deliver on our strategic initiative to enhance our pipeline and expand into additional specialized markets," said James C. Mullen, Biogen Idec's President and chief executive officer (CEO). "Syntonix brings promising science and technology to areas of unmet medical need such as haemophilia, and we look forward to building on their expertise with Biogen Idec's global development, manufacturing, and commercial capabilities." "In pursuing next steps for Syntonix, joining forces with Biogen Idec was the best option for all stakeholders, including - over the long-term - patients," said John W. Ripple, CEO of Syntonix. "As a global leader in bio-manufacturing and serving niche markets, Biogen Idec is well-poised to deliver on the promise of haemophilia therapies that require less frequent dosing." The transaction is expected to close in the first quarter of 2007. Upon completion, Biogen Idec will acquire all of the issued and outstanding shares of the capital stock of Syntonix for $40 million, payable at closing, and potential additional payments of up to $80 million upon the achievement of certain development milestones. Contingent on the closing of the acquisition, Biogen Idec plans to maintain Syntonix's 25,000 square-foot facility in Waltham, MA for the continuing operation of Syntonix programmes. The transaction, which has been approved by the boards of directors of both companies, is subject to customary closing conditions. FIX:Fc is being developed for the treatment of haemophilia B in a strategic alliance with Biovitrum AB of Sweden with the companies sharing equally the costs and profits of development and commercialization. After regulatory approval, Syntonix is responsible for marketing FIX:Fc in North America and Biovitrum is responsible for marketing FIX:Fc in Europe, Russia, and the Middle East. Syntonix is pursuing other early-stage programs, including a long-acting factor VIII programme, with the potential to improve the treatment of haemophilia A. In developing novel and improved treatments, the company uses propriety technology, including the SynFusion and Transceptor platforms. SynFusion drugs are based on proprietary Fc-fusion technology to create long-acting biopharmaceuticals with reduced dosing frequencies. Specifically, the SynFusion technology links a single copy of the drug to the Fc region on an antibody to optimize the pharmacokinetic and pharmacodynamic properties of the biopharmaceutical and extending its circulating half-life. Transceptor is a proprietary technology that enables pulmonary delivery of a SynFusion or Fc-fusion drug. The natural FcRn pathway transports antibodies and Fc-fusion drugs across the epithelial cell barrier in the lungs. Haemophilia is a rare, inherited bleeding disorder that is caused by mutations that impair or eliminate the production of essential clotting factors naturally found in the blood. Haemophilia B, caused by mutations in the factor IX gene, affects approximately 3,600 people in the Unites States. Haemophilia A, caused by mutations in the factor VIII gene, affects approximately 14,500 people in the U.S. Both forms of haemophilia are characterized by spontaneous or prolonged bleeding for which there is no cure. Today a majority of haemophilia patients are treated with recombinant-derived factor VIII and IX products. Increasingly, younger patients are prescribed prophylaxis regimens with these products to prevent bleeding, rather than receiving treatment at the time.
