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.

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.
