FDA OKs 1st Drug From Genetically Altered Animals

The Food and Drug Administration made history Friday as it approved the first drug made with materials from genetically engineered animals, clearing the way for a new class of medical therapies. GTC Biotherapeutics said regulators cleared its drug ATryn, which is manufactured using milk from goats that have been scientifically altered to produce extra antithrombin, a protein that acts as a natural blood thinner. The drug's approval may be the first step toward new kinds of medications made not from chemicals, but from living organisms altered by scientists. Similar drugs could be available in the next few years for a range of human ailments, including haemophilia.
