TOP HAT: Trial of a licensed drug as a Parkinson's Hallucination Treatment

Research teams across the UK are investigating if ondansetron has a meaningful treatment effect on Parkinson's and Lewy Body Dementia hallucinations.

As this is an already licensed low-cost drug, if the research shows significant outcomes, ondansetron could be available for people with Parkinson's who experience hallucinations within the next few years.

Who

306 people diagnosed with Parkinson's or Lewy Body Dementia (LBD) who experience hallucinations at least once a week. You also need to not be taking apomorphine and be on a stable dose of your Parkinson's or LBD medication for 28 days before starting the research.

What

The first activity is a telephone call to discuss the research more fully, and complete some questionnaires. This will be followed by a brief face-to-face visit to assess your Parkinson’s, take a blood sample, and monitor your heart rhythm.

If you are eligible to take part, you will either receive ondansetron or dummy medication tablets for 12 weeks, which will be shipped to you via a courier. The research team will maintain regular contact throughout to take assessments and let you know how much medication to take. This contact will be through telephone, video call, and face-to-face. 

All face-to-face visits can take place either at your home or at your local study site, it's up to you.
