Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals diagnosed with Alzheimer's Disease who exhibit symptoms of psychosis and meet specific eligibility criteria.

Probably not a fit

Patients without a confirmed diagnosis of Alzheimer's Disease or those not experiencing psychosis may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter, randomized, double-blind, parallel-group, placebo-controlled study aims to assess the efficacy, safety, and tolerability of ITI-1284 in patients experiencing psychosis associated with Alzheimer's Disease. The trial consists of a screening period to determine eligibility, a 6-week double-blind treatment phase where participants receive either ITI-1284 or a placebo, and a 30-day safety follow-up period. The study will evaluate how well ITI-1284 works compared to placebo in alleviating psychotic symptoms in this patient population.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the management of psychosis in Alzheimer's patients, enhancing their quality of life.

How similar studies have gone: Previous studies have explored treatments for psychosis in Alzheimer's, but the specific approach with ITI-1284 is novel and has not been extensively tested.
