BordeauxAges 18 years+ - NCT04664634RecruitingPhase 3
Digital treatment for drooling and swallowing in Parkinson’s
This trial tests a smartphone/tablet digital program meant to help with drooling (sialorrhea) and swallowing problems in people with Parkinson’s disease. If you’re eligible, you’ll use the platform during clinic study visits to see whether it can improve symptoms and safety.
Evanston, IllinoisAges 22 years+ - NCT04650932Recruiting
Study tests new stimulation settings for advanced Parkinson’s
This study looks at whether changing how deep brain stimulation (DBS) pulses are delivered can improve symptoms in people with advanced Parkinson’s disease. You may be eligible if you already have a specific Boston Scientific DBS device and have had it implanted for at least 3 months.
Sacramento, CaliforniaAges 18 years+ - NCT04477785Recruiting
Study to track Parkinson’s signs using imaging, spinal fluid, and genes
This study is building a large, detailed group of people—some with Parkinson’s and some at higher risk—to understand early changes over time. It uses brain imaging (DaTscan SPECT), sometimes spinal fluid tests (lumbar puncture), and genetic information to help researchers better measure disease and develop future treatments.
Birmingham, AlabamaAges 30 years+ - NCT04373317RecruitingPhase 4
Comparing two medicines for hallucinations in Parkinson's disease
This study compares two drugs, pimavanserin and quetiapine, to see which works better for hallucinations or delusions caused by Parkinson's disease. The goal is to help patients manage these symptoms more effectively.
Tucson, ArizonaAges 40 years+ - NCT03836950RecruitingPhase 1/Phase 2
Brain stimulation to improve thinking in Parkinson’s
This trial studies a noninvasive treatment called rTMS to help improve thinking and memory in people with Parkinson’s who have mild cognitive problems. It may help strengthen brain function, but it also has strict safety and eligibility rules to protect against seizure and metal-related risks.
Chicago, IllinoisAges 50 years+ - NCT03457493RecruitingPhase 1/Phase 2
TSPO brain scan study in Parkinson’s disease
This trial looks at brain inflammation in people with Parkinson’s using a special PET scan. The goal is to understand how brain immune activity may relate to Parkinson’s, and how the scan results change over time.
Birmingham, AlabamaAges 30 years+ - NCT03174938Recruiting
BioFINDER 2 study for healthy aging and memory problems
This study uses brain scans and a spinal fluid test to better understand memory and thinking changes in different groups, from people with healthy thinking to early or established dementia. If you qualify, it may help researchers learn what’s driving these conditions and how they progress.
ÄngelholmAges 20–100 - NCT03025334Recruiting
Brain stimulation study for thinking changes in Parkinson’s
This study tests whether a non-invasive brain stimulation approach (tDCS) can improve thinking and memory in people with Parkinson’s disease. You may be invited because your Parkinson’s is typical and your memory testing shows you do not have dementia.
Winnipeg, ManitobaAges 40 years+ - NCT02763683Recruiting
Study brain changes in Parkinson-related dementia
This study looks at brain features linked to dementia in people who have Parkinson disease. It may help researchers understand why dementia happens in Parkinson and how it could be detected or treated in the future.

Common questions
- Are there clinical trials for parkinson?
- Yes. Clin2 currently lists 735 recruiting parkinson studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a parkinson trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a parkinson trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
