Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals diagnosed with Alzheimer's disease who exhibit agitation and meet specific biomarker criteria.

Probably not a fit

Patients without a confirmed diagnosis of Alzheimer's disease or those who do not exhibit agitation may not benefit from this study.

What this trial studies

This multicenter, randomized, double-blind, placebo-controlled study aims to assess the efficacy, safety, and tolerability of ITI-1284 in patients experiencing agitation associated with Alzheimer's dementia. The trial consists of three periods: a screening phase lasting up to four weeks, a 12-week double-blind treatment phase where participants receive either ITI-1284 or a placebo, and a 30-day safety follow-up period after treatment. The study will evaluate how well ITI-1284 alleviates agitation symptoms compared to a placebo.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce agitation symptoms in Alzheimer's patients, improving their quality of life.

How similar studies have gone: Other studies have explored treatments for agitation in Alzheimer's patients, but the specific approach with ITI-1284 is novel.
