Is this trial a fit for you?

Likely a good fit

Adults 55–90 years old with a prior diagnosis of Alzheimer's disease dementia, clinically significant moderate-to-severe agitation per the IPA definition, required AD biomarker/neuroimaging, and a caregiver who can participate in study visits are the intended participants.

Probably not a fit

People whose agitation is primarily due to a different condition or non-AD dementia, those with uncontrolled seizures or epilepsy, or those outside the age range or unable to attend study visits are unlikely to benefit from this trial.

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

What this trial studies

This Phase 2/3, multicenter, double-blind, placebo-controlled, three-arm randomized trial will enroll about 300 participants across up to 60 sites in the US, Canada, and Europe. Participants must have a prior diagnosis of Alzheimer's disease dementia, clinically significant agitation meeting the International Psychogeriatric Association (IPA) definition, supporting neuroimaging after dementia onset, and a Core 1 AD biomarker. Eligible participants will be randomized roughly 1:1:1 to EXV-802, EXV-801, or placebo and followed for safety and changes in agitation symptoms. Caregivers must be available to provide regular contact and assist with study procedures.

Why it matters

Potential benefit: If successful, these medicines could reduce agitation symptoms, improving daily life for patients and easing caregiver burden.

How similar studies have gone: Pharmacologic trials for agitation in Alzheimer's have produced mixed results and few new approved options, so this approach is somewhat novel and exploratory compared with existing off-label treatments.
