Clinical trials

Every Alzheimer's trial in our copy of the ClinicalTrials.gov registry — completed, running and abandoned. Filter it, then follow the link to the official record.

If you are thinking about joining a trial

A listing here is a record that a study was registered. It is not a recommendation, and it does not mean the study is still recruiting or that anyone is eligible. Registry entries go stale.

Talk to the treating doctor first, then contact the study team listed on the official ClinicalTrials.gov record. The NIA's free referral line can help you look: 1-800-438-4380, weekdays, English and Spanish.

Clear filters Download all 7,816 as CSV

"Open to new participants" means the registry status is RECRUITING or NOT_YET_RECRUITING — 1,523 of the 7,816 records. That is what the sponsor last told the registry, which can be months out of date.
Location is by country. This pull of the registry records the countries a study runs in, not its individual sites, so we cannot filter by US state or city — and we are not going to guess one. To find the nearest site, open a trial's record below: the official page lists every location with its contact details.

What could make this misleading

Sponsors enter their own data and do not always keep it current, so "recruiting" can be out of date by months or years. Enrollment figures may be targets rather than actual numbers; the downloaded file says which for each trial. Trials that were never registered do not appear at all, and the intervention class is this project's own grouping, not the registry's.

Always check the official record before acting on anything here. This is a summary, not medical advice.
