Trial overview

Official title: Study AZ3110865, a study comparing SB-742457 or donepezil versus placebo in subjects with mild-to-moderate Alzheimer’s disease
Trial description: The study is designed to investigate the efficacy, safety and tolerability of SB-742457 versus placebo in subjects with mild-to-moderate Alzheimer’s disease. SB-742457 is an experimental treatment which increases the levels of certain chemicals in the brain that are often decreased in patients with Alzheimer’s disease.
Primary purpose:
Treatment
Trial design:
Parallel Assignment
Masking:
Double (Participant, Investigator)
Allocation:
Randomized
