About
To compare the efficacy of 2 fixed doses of brexpiprazole with placebo in participants with agitation associated with dementia of the Alzheimer's type.
Full description
Behavioral symptoms, such as agitation, are core features in participants with Alzheimer's disease and related dementias and develop in the majority of dementia participants. The presence of agitation in participants with Alzheimer's disease places a significant burden not only on participants and their caregivers but also on the healthcare system.
This is a trial designed to assess the safety and efficacy of brexpiprazole in the treatment of participants with agitation associated with dementia of the Alzheimer's Type. The trial consists of a continuous 12-week double-blind treatment period with a 30-day follow-up. The trial population will include male and female participants 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 participant is not living alone.
