Is this trial a fit for you?

Ideal candidates are adults aged 55 to 90 diagnosed with Alzheimer's Disease and experiencing moderate to severe psychotic symptoms.

Probably not a fit

Patients whose psychotic symptoms are primarily due to conditions other than Alzheimer's Disease will 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 study aims to assess the safety and effectiveness of KarXT in adults aged 55 to 90 who have been diagnosed with Alzheimer's Disease and are experiencing moderate to severe psychosis. Participants will be randomly assigned to receive either KarXT or a placebo, with the goal of determining how well KarXT alleviates psychotic symptoms associated with Alzheimer's. The study will include patients with confirmed Alzheimer's biomarkers and a history of psychotic symptoms for at least two months. The trial is designed to provide insights into a potential new treatment option for this challenging condition.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for Alzheimer's patients suffering from psychosis.

How similar studies have gone: Other studies have explored treatments for psychosis in Alzheimer's, but the specific use of KarXT represents a novel approach.
