D6 and D7 were both gamma secretases. They never got a BACE into the clinic.

D5 failed Ph 2, and that study ended 25 months ago. Have you ever heard of another biotech company shelving a very promising project for 25 months, one that eventually go approved. After I saw the initial data, I tried to let everyone know that this product was dead for AD.

if bapi is sucessful, they might try to revive it, but the ph 2 data was very bad, and i don't think it will ever work for AD>
