Inclusion Criteria
\- A diagnosis of Alzheimer's disease (AD) in accordance with the 2024 Alzheimer's Association criteria with one of the following confirmations of AD pathology:
i) Historical evidence of AD diagnosis with amyloid positron emission tomography (PET), Aβ42/40 ratio in CSF, pTau181/Aβ42 ratio in CSF or pTau217/Aβ42 ratio in plasma using an Health Authority (HA)-authorized diagnostic assay.
ii) If no historical evidence available:
A. A plasma biomarker will be assessed for eligibility if allowed per regulatory requirements. The test cutoff(s) will be based on diagnostic use approval.
B. If a plasma biomarker assay cannot be used or if the assay result is inconclusive, conduct one the following:
* Amyloid PET.
* Aβ42/40 ratio or pTau181/Aβ42 ratio in CSF using an HA-authorized diagnostic assay.
* Mini-Mental State Examination (MMSE) score of 5 to 22, inclusive, at Screening (Visit 1).
* Have one identified caregiver who should have sufficient contact (approximately 10 hours a week or more) and is willing to:
i) Attend all visits and report on participant's status.
ii) Oversee participant compliance with medication and study procedures.
iii) Participate in the study assessments and provide informed consent to participate in the study.
* History of agitation that meets the International Psychogeriatric Association (IPA) consensus definition for agitation in cognitive disorders with onset at least two weeks prior to Screening (Visit 1).
* AD parti…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial is testing KarXT plus KarX-EC specifically for agitation in Alzheimer's disease — is agitation one of my loved one's main symptoms right now, and does that make this trial worth considering compared to what's already available?
2Since this is a Phase 3 trial, there's more safety data than earlier phases, but the drug isn't fully approved yet — what do we know so far about the safety profile of KarXT for people with Alzheimer's, and what side effects should we watch out for?
3The trial runs for 14 weeks and measures changes on a specific agitation rating scale called the CMAI-IPA — what does that commitment look like in terms of clinic visits, caregiver involvement, and monitoring, and is that realistic for our situation?
4Are there already approved medications or non-drug approaches for Alzheimer's-related agitation that we should try first before considering a clinical trial like this one?
5Since the trial is actively recruiting, what would the enrollment process look like, and are there specific stages of Alzheimer's disease or levels of agitation severity that would be required to participate — even if just to understand whether it's worth exploring further with you?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
