Comparing High vs Standard Resolution PET Imaging in Prodromal Parkinson’s Disease
We’re testing whether a high-resolution PET camera provides clearer images than a standard one for people in the prodromal phase of Parkinson’s disease.
-
Early PD signals in people with REM sleep behavior disorder
This study tests whether people with REM sleep behavior disorder show early signs of Parkinson’s disease before classic symptoms appear.
-
Gut-brain in PD Consortium: understanding gut influences in Parkinson's and prodromal stages
This study tests how the gut and brain communicate in people with Parkinson's, those without PD, and those at risk, to see if gut factors relate to disease onset and progression.
-
Early longitudinal AV-133 PET imaging in people with prodromal Parkinson's
This study will try repeated 18F-AV-133 PET scans over two years to track early brain changes in people with prodromal Parkinson's.
-
Using saliva and extracellular vesicles to diagnose neurodegenerative diseases
This study is testing a new way to diagnose neurodegenerative diseases like Alzheimer's and Parkinson's by analyzing saliva samples to see if it can help identify these conditions earlier and tailor treatments for patients.

Quick answers
How many Prodromal Parkinson's Disease clinical trials are recruiting right now?
5, as of November 12, 2026. We update this list each time we refresh our data from ClinicalTrials.gov.
Where are these trials running?
In 8 countries. The most sites are in United States (3 trials), Italy (1 trial), Canada (1 trial), Germany (1 trial), Israel (1 trial). Each study page lists its sites and which ones are recruiting.
What phases are they in?
Phase 2: 2. Trials with no phase listed are usually device, behavioural or observational studies.
How do I join one?
Open a study, check the "Is this trial a fit for you?" section, then contact the study team listed on the page. They will ask a few screening questions. Asking is free and does not commit you to anything. Talk it over with your doctor first.
