Alzheimer Disease study: Nabilone

Official title Nabilone for Agitation Blinded Intervention Trial

ClinicalTrials.gov ID: NCT04516057

What this study is testing

What is Nabilone?

An investigational oral medication being studied as a potential treatment for agitation in Alzheimer's disease. It is designed to activate cannabinoid receptors in the brain, which may influence mood and behavior.

Also referred to as Cesamet.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study wants to find out if nabilone can safely reduce agitation and improve overall brain‑related symptoms, caregiver stress, nutrition and pain in Alzheimer’s patients.
Who it's for
Adults with Alzheimer’s disease who are experiencing agitation.
What's involved
You will be randomly assigned to take either nabilone or a placebo for 8 weeks and will have regular check‑ups and simple tests to measure agitation, thinking ability, nutrition, pain and caregiver stress.
Time commitment
The trial lasts about 16 weeks total – 8 weeks of taking the study medication and another 8 weeks of follow‑up, with several clinic visits during that time.
  • Phase 3: a large, late-stage study
  • You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
