Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a multicenter, randomized, double-blind, parallel-group, placebo-controlled, flexible-dose study evaluating the efficacy, safety, and tolerability of ITI-1284 compared with placebo in the treatment of psychosis in patients with AD.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 (6 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.
