October 31, 2018 updated by: Allergan
A Phase 1b, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multicenter Study to Determine the Safety, Tolerability, Pharmacokinetics, and Brain Metabolic Response, Using FDG-PET, Following Administration of AGN-242071 Added to Standard-of-Care (Donepezil ± Memantine) in Participants With Mild to Moderate Alzheimer's Disease
This is a study to evaluate the brain metabolic response using Fluorodeoxyglucose Positron Emission Tomography (FDG-PET), safety, tolerability and pharmacokinetics of AGN-242071 in patients with mild to moderate Alzheimer's Disease on a stable dose of 10 mg donepezil with or without memantine standard of care.
