Pfizer (PFE) says an experimental Alzheimer's treatment it's working on with Johnson & Johnson (JNJ) unit Janssen Pharmaceuticals did not meet clinical endpoints in a late-stage study. In the study, patients with mild-to-moderate Alzheimer's disease given an intravenous form of the drug bapineuzumab didn't fare any better in cognitive and functional performance than those given a placebo. Elan (ELN), which holds a 49.9% equity interest in Janssen Alzheimer Immunotherapy, is taking a big hit after hours: PFE -1.3%, JNJ -0.2%, ELN -16.8%.
