Atryn is a recombinant antithrombin. Meanwhile, across the pond, the U.

Biotechnology analyst Philip Nadeau at Cowen and Company in New York told The Scientist ATryn’s approval “removes any lingering concerns that proteins manufactured like this simply aren’t approvable. For additional information regarding Atryn or the prevention of peri-operative and peri-partum thromboembolic events, please visit the Atryn web page. The efficacy was assessed during treatment with AT and up to 7 days after stopping AT treatment.

Transfusion March;43 3: The drug candidate rhC1INH from Pharming Group in the Netherlands, which is directed against hereditary angioedema, is derived from transgenic rabbits, and received a fast-track designation for review by the FDA on July So many drugs are produced by traditional cell culture methods, and the pharmaceutical industry doesn’t like deviating too far from the trodden path. These single-arm, open-label studies were conducted in 31 ATryn treated hereditary antithrombin AT deficient patients and 35 human plasma-derived AT treated hereditary AT deficient patients.

Atryn is specifically indicated for the prevention of peri-operative and peri-partum thromboembolic events in hereditary antithrombin deficient patients.

Recombinant antithrombin is produced by recombinant DNA technology using genetically engineered goats into which the DNA coding sequence for human antithrombin has atrgn introduced, along with a mammary gland specific DNA sequence, which directs the expression of the antithrombin into the milk. AT neutralizes the activity of thrombin and Factor Xa by forming a complex which is rapidly removed from the circulation.
