Summary

This study compares the efficacy of 2 doses of brexpiprazole with placebo in subjects with agitation associated with dementia of the Alzheimer's type.

Description

This is a phase 3, 12-week, multicenter, randomized, double-blind, placebo-controlled, fixed-dose trial designed to assess the efficacy, safety, and tolerability of brexpiprazole compared with placebo. The trial consists of a 12-week double-blind treatment period with a 30 day follow-up. The trial population will include male and female subjects between 55 and 90 years of age (inclusive) with a diagnosis of probable Alzheimer's disease, who are residing either in an institutionalized setting or in a non-institutionalized setting where the subject is not living alone. This trial will analyze data gathered from 330 subjects at multiple countries. An interim analysis will be conducted when a targeted sample of the first 255 subjects has completed or discontinued the trial. Subjects may also be eligible to enter an active extension trial.
