Descriptive Information
Brief Title  ICMJE Safety and Tolerability Study of Flexible Dosing of Brexpiprazole in the Treatment of Subjects With Agitation Associated With Dementia of the Alzheimer's Type
Official Title  ICMJE A Phase 3, 12-week, Multicenter, Randomized, Double-blind, Placebo-controlled Trial to Evaluate the Efficacy, Safety, and Tolerability of Flexible Dosing of Brexpiprazole (OPC-34712) in the Treatment of Subjects With Agitation Associated With Dementia of the Alzheimer's Type
Brief Summary To compare the efficacy of flexible dosing of brexpiprazole with placebo in subjects with agitation associated with dementia of the Alzheimer's type
Detailed Description

Behavioral symptoms, such as agitation, are core features in subjects with Alzheimer's disease and related dementias and develop in the majority of dementia subjects. The presence of agitation in subjects with Alzheimer's disease places a significant burden not only on subjects and their caregivers but also on the healthcare system.

This is a trial designed to assess the safety and efficacy of flexible dosing of brexpiprazole in the treatment of subjects with agitation associated with dementia of the Alzheimer's type. 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.
