I still am curious as to why Shire walked away from Amigal in Phase 3
Shire walked away because Pilcera for Gaucher failed phase II study. Gaucher has much bigger market than Fabry, and the failure probably raised question whether it would succeed in Fabry as well. In addition, Shire already had ERT in both Gaucher (approved this year) and Fabry (pending at FDA).
