Gut nerve cell biomarkers study for Parkinson’s risk
Part of Brain & nervous system clinical trials.
This trial studies nerve cell “biomarkers” from the gut to learn whether they can help detect Parkinson’s disease (or related conditions) earlier. You may be asked to undergo a colonoscopy to collect gut tissue for testing.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 45 and 75 years old.
- You have Parkinson’s disease or are at higher risk for it (for example, REM sleep behavior disorder or a close relative with Parkinson’s).
- Your Parkinson’s stage is mild to moderate (Hoehn and Yahr score 1 to 4).
- You can safely have a colonoscopy (no colonoscopy or anesthesia contraindications) and can consent to participate.
- You do not have certain other brain/nerve diseases (like Alzheimer’s, PSP, or multiple sclerosis) or other major health problems that would limit life expectancy or interfere with the study.

Other trials that look related to this one.
This study looks at how your gut's immune system relates to brain and nerve diseases. Researchers will collect samples during a colonoscopy to better understand connections between gut health and neurologic conditions like multiple sclerosis or Parkinson's disease.
This trial uses a small piece of colon tissue, taken during a routine colonoscopy, to look for a protein linked to Parkinson's disease and REM sleep behavior disorder (RBD). It aims to improve diagnosis for these conditions.
This study tests whether a protein in colon tissue can help diagnose Parkinson's disease. People with Parkinson's who already need a routine colonoscopy may participate.
This study looks at how digestive (gut) problems happen in people with Parkinson’s and whether there are related changes in the nerve tissue in the digestive tract. It may help researchers better understand the cause of these symptoms and find new ways to monitor or treat them.
This study is looking at how the bacteria in your gut might affect your brain in Parkinson's disease. It involves two types of brain scans to see differences between people with Parkinson's and healthy volunteers.
This study is looking to improve how Parkinson’s and related brain conditions are identified and treated sooner. You may be asked to share your health information and provide blood or other samples, and possibly have procedures like a spinal fluid test or a small skin sample.
