What is the primary objective of this study?

To compare the efficacy of flexible dosing of brexpiprazole with placebo in subjects with agitation associated with dementia of the Alzheimer's type

Who is eligible to participate?

Exclusion Criteria: - Subjects with dementia or other memory impairment not due to Alzheimer's disease. - Subjects with history of stroke, well-documented transient ischemic attack, or pulmonary or cerebral embolism. - Subjects who currently have clinically significant neurological, hepatic, renal, metabolic, hematological, immunological, cardiovascular, pulmonary, gastrointestinal, or psychiatric disorders. - Subjects who have been diagnosed with an Axis I disorder (DSM-IV-TR criteria). - Subjects with uncontrolled hypertension. - Subjects with uncontrolled insulin-dependent diabetes mellitus (IDDM) - Subjects with epilepsy or a history of seizures. - Subjects considered in poor general health based on the investigator's judgment.

Drug:Brexpiprazole, OPC-34712Flexible dose of 0.5 to 2 mg/day or placebo tablets for up to 12 weeks

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

PlaceboMatching Placebo Once-Daily

Brexpiprazole (flexible dose range 0.5 to 2 mg)Titrate up from 0.25 mg/day brexpiprazole to 1 mg/day brexpiprazole. After achieving 1 mg/day target dose may be increased or decreased based on efficacy and tolerability. Allowable flexible doses will be 0.5 mg/day, 1 mg/day, or 2 mg/day.
