Study Evaluating TheSafety And Efficacy Of PF-05212377 Or Placebo In Subjects With Alzheimer's Disease With Existing Neuropsychiatric Symptoms On Donepezil
A Randomized, 18-week, Placebo-controlled, Double-blind, Parallel Group Study Of The Safety And Efficacy Of Pf-05212377 (Sam-760) In Subjects With Mild-to-moderate Alzheimer's Disease With Existing Neuropsychiatric Symptoms On A Stable Daily Dose Of Donepezil
This study will evaluate safety and efficacy of PF-05212377 in subjects with mild-to-moderate Alzheimer's Disease with existing neuropsychiatric symptoms on a stable dose of Donepezil. The 4-week run-in will minimize placebo effect. The 12-week treatment period is considered the minimum length necessary to reliably evaluate the effect PF-05212377 on cognition and and neuropsychiatric symptoms in this population. The 2-week washout will allow to monitor re-emergence of neuropsychiatric and cognitive symptoms.
