News Release - August 2, 2006
European Commission Approves ATryn(R)FRAMINGHAM, Mass.--(HSMN NewsFeed)--Aug. 2, 2006--GTC Biotherapeutics, Inc. ("GTC", Nasdaq: GTCB) reported today that the European Commission has granted market authorization to ATrynŽ, GTC's recombinant form of human antithrombin, for the prophylaxis of venous thromboembolism in surgery of patients with congenital antithrombin deficiency. Antithrombin is a naturally occurring plasma protein that has both anticoagulant and anti-inflammatory properties. GTC produces ATrynŽ in the milk of goats that have a transgene for human antithrombin. ATrynŽ is the first transgenically produced protein to be approved for human therapeutic use anywhere in the world. ATrynŽ is also the first recombinant antithrombin product approved anywhere in the world and the first antithrombin product, whether recombinant or derived from the human blood supply, that has been approved through the centralized EMEA procedure for use in all 25 countries of the European Union.
The European Commission approval follows on the positive opinion determined by the Committee for Medicinal Products for Human Use of the European Medicines Agency on June 2, 2006. The positive opinion was based on an extensive review of the application submitted in January 2004.
Patients with a hereditary antithrombin deficiency are prone to developing blood clots. These patients may normally be maintained on an oral blood thinning agent. When a hereditary deficient patient is undergoing a high risk procedure, such as surgery, the blood thinning medication is typically discontinued to minimize the risk of excessive bleeding. Supplementation of low antithrombin levels with ATrynŽ may be utilized during these high risk procedures to allow for appropriate functioning of the natural coagulation management system. ATrynŽ is administered by infusion in a hospital setting during the high risk procedure. The hereditary deficient population is estimated to be about 1 in 5,000 and has been dependent upon plasma-derived antithrombin products for use during high risk procedures. GTC's recombinant form of antithrombin will offer an alternative to treatment with plasma-derived product and a consistent availability of product throughout the European Union, once reimbursement rates are obtained.
Negotiation of the reimbursement rates with each country's health system and establishment of sales and marketing efforts in Europe will be performed by GTC's partner, LEO Pharma A/S. GTC will continue to produce the product, receiving a transfer price from LEO as well as a royalty on commercial sales. Market launch is targeted for the second quarter of 2007 as reimbursement rates are finalized. LEO will also make a non-refundable $2 million milestone payment to GTC for receipt of the European market authorization.
