ADAGIO-1: KarXT + KarX-EC for Agitation in Alzheimer's Disease

This study is testing a combination of two medications, KarXT and KarX-EC, to see if they can safely and effectively reduce agitation in people with Alzheimer's disease. We are looking for adults between 55 and 90 years old who have been diagnosed with Alzheimer's disease, confirmed by specific tests like amyloid PET scans or spinal fluid analysis. The main goal is to measure changes in agitation levels using a standard assessment tool after 14 weeks. The study plans to enroll 426 participants, but its current recruitment status is unclear.

Study design
This is an interventional study, meaning participants will receive a specific treatment. It involves testing KarXT + KarX-EC, KarX-EC alone, or a placebo (an inactive substance) in about 426 participants.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
The primary outcome is measured at Week 14, indicating participants will be followed for at least that long.
