ATryn approved for anticoagulation

The FDA has approved ATryn (antithrombin [recombinant], from GTC Biotherapeutics and Ovation Pharmaceuticals), an anticoagulant for the prevention of peri-operative and peri-partum blood clots in patients with hereditary antithrombin (AT) deficiency. ATryn is a therapeutic protein derived from the milk of goats that have been genetically engineered by introducing a segment of DNA into their genes (called a recombinant DNA or rDNA construct) with instructions for the goat to produce human antithrombin in its milk.  

ATryn is expected to be available in the second quarter of 2009.
