>What would stop Merck (with bio engineered yeast) from also getting approval and selling AT if GTCB gets approval in US for HD or in Europe for DIC?<
Following up on urche’s comments, the HD indication is too small a market to attract other players. DIC, on the other hand, will attract other players—indeed there already is a serious competitor in Artisan Pharma’s thrombomodulin (#msg-14524596). If you are going to worry about competition, that’s the place to focus, IMO. Regards, Dew
