Drug from goat's milk

The first genetically-engineered animal approved for commercial use could be a goat that produces an anti-clotting drug in its milk (learn how it works).

A Food and Drug Administration (FDA) evaluation found the drug Atryn to be safe and effective. There are still more steps in the FDA's drug-approval process.

The drug is being produced by GTC Biotherapeutics for use in people with a hereditary disorder that makes them vulnerable to life-threatening blood clots. It is used during surgery and childbirth.

If the drug is approved, it would be the first application under new FDA regulations that allow animals to be genetically altered to produce drugs, model human disease, produce industrial or consumer products, or improve their use as food.
