简要总结
This is a multicenter, randomized, double-blind, placebo-controlled, flexible-dose study of the efficacy, safety, and tolerability of ITI-1284 in patients with agitation associated with Alzheimer's dementia
详细描述
The study will be conducted in 3 periods: * Screening Period (up to 4 weeks) during which patient eligibility will be assessed; * Double-blind Treatment Period (12 weeks) during which all patients will be randomized in a 1:1 ratio to receive either ITI-1284 or placebo; * Safety Follow-up Period (30 days) during which all patients will return for a safety follow-up visit approximately 30 days after the last dose of study drug.

结局指标
主要结局
Cohen-Mansfield Agitation Inventory (CMAI) total score
时间窗: Week 12
The CMAI is a reliable and validated, 29-item caregiver-rating questionnaire to assess agitated behavior in elderly patients. Each item is rated on a 7-point scale of frequency, from "never" (1) to "several times an hour" (7), with 1 being the "best" rating and 7 being the "worst" rating. The minimum possible CMAI total score is 29, and the maximum possible CMAI total score is 203.
次要结局
- Clinical Global Impression-Severity (CGI-S) Score(Week 12)
