Overview
The goal of this clinical trial is to evaluate the safety and efficacy of EXV-802 and EXV-801 in treatment of agitation in participants with Alzheimer's Disease dementia.
Description
This is a Phase 2/3 multicenter, double-blind, placebo-controlled, three-arm, multicenter study evaluating the safety and efficacy of EXV-802 and EXV-801 in treatment of agitation in participants with Alzheimer's Disease dementia. The diagnosis of agitation will be based on the consensus definition for agitation in patients with cognitive disorders developed by te International Psychogeriatric Association (IPA) Agitation Definition Work Group as well as neuroimaging performed after onset of dementia symptoms and a Core 1 AD biomarker.

Following screening procedures for assessment of inclusion and exclusion criteria, eligible participants will be randomized into the study. Approximately 100 patients per arm will be randomized (300 total).
