Just keep in mind that their collaboration with Allergan is up in March. That would be bad news if the collaboration wasn't going well...it appears to be going great. Allergen might just decide to buy Acadia here...we're certainly trading like it. I would buy Acadia and then give a contigency right if anything good ever happens with pimavanserin. Offer $4.00 and then another several dollars if pima makes it to market.
