Parkinson's disease database study in Brazil
This study is creating a database of motor and non-motor symptoms in people with Parkinson's disease in Brazil. It aims to better understand the condition by collecting information, and participation involves tests and questionnaires.
Brasília, Federal DistrictAges 18–120 - NCT06508801Recruiting
Blood flow restriction to improve balance in Parkinson's
This study tests whether gently restricting blood flow to your legs during exercise can help improve balance for people with Parkinson's disease. You will do simple leg exercises while wearing a special cuff, which may strengthen muscles and improve steadiness.
San Antonio, TexasAges 40–85 - NCT05516732Recruiting
Testing serotonin activity in the brain in people with Parkinson’s
This study uses special scans to measure how serotonin is released in parts of the brain involved in movement in Parkinson’s disease. It may help researchers understand disease changes and the role of serotonin systems in movement problems.
Exeter, DevonAges 25–85 - NCT05516719Recruiting
Study tracking I2BS in Parkinson’s over time
This study follows people with Parkinson’s to see how “I2BS” changes over time using special brain scans and other tests. It may help researchers better understand Parkinson’s and improve how it’s measured in future trials.
Exeter, DevonAges 25 years+ - NCT05962489Recruiting
Sleep-focused DBS therapy study for Parkinson’s disease
This study looks at a sleep-focused approach to brain stimulation (DBS) in people with Parkinson’s disease. You may be able to join if you’re planning or scheduled for specific DBS surgery at the University of Minnesota and have the needed brain imaging.
Minneapolis, MinnesotaAges 21 years+ - NCT04735458Recruiting
Brain network study for Parkinson’s or essential tremor
This study looks at how “inhibitory control” brain networks work in people with Parkinson’s disease or essential tremor. If you are eligible for surgery and can do the study tasks, your results may help researchers better understand movement disorders and guide future treatments.
Birmingham, AlabamaAges 18 years+ - NCT05748028Recruiting
Testing treatment for pain and nerve symptoms in Parkinson’s
This study looks at pain and “autonomic” (automatic body) symptoms in people with Parkinson’s disease or a related condition called multiple system atrophy. It aims to understand what helps and to learn more about these symptoms in different types of Parkinson-like illnesses.
Telese Terme, BeneventoAges 18 years+ - NCT05568498RecruitingPhase 2
Probiotic trial for depression in Parkinson’s disease
This Phase 2 study tests whether taking probiotics can improve depression and mood symptoms in people with Parkinson’s disease. It’s meant for those with mild to moderate depression and stable Parkinson’s and mood treatments.
Vancouver, British ColumbiaAges 40–80 - NCT05065060Recruiting
Parkinson study tracking health online and long-term
This study aims to better understand Parkinson’s disease over time by collecting health information online. You may join if you have Parkinson’s, or if you don’t, to compare changes and help researchers find useful markers.
San Francisco, CaliforniaAges 18 years+ - NCT04566341Enrolling by invitation
Study gut problems in Parkinson’s and changes in gut nerves
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.
Boston, MassachusettsAges 40–85 - NCT05152394RecruitingPhase 1
Testing cord stem cell exosome treatment for Parkinson’s safety
This Phase 1 study tests whether a treatment made from donated umbilical cord “exosomes” is safe in people with Parkinson’s disease. It mainly looks at side effects and safety, and could help guide future treatments if it proves tolerable.
Naples, FloridaAges Any age - NCT07505394Recruiting
Preventing impulse control side effects from Parkinson's medication
This study tests a computer-based tool that aims to predict and prevent impulse control disorders (like compulsive gambling or shopping) caused by certain Parkinson's medications. If you take a dopamine agonist, this tool might help your doctor adjust your treatment to avoid these side effects.
ParisAges 18 years+ - NCT06638944RecruitingPhase 2
Wearable feedback device for swallowing therapy in stroke or Parkinson's
This study tests a wearable device that provides feedback to help improve swallowing in people with stroke or Parkinson's disease. It may help make swallowing therapy more effective by showing real-time progress during exercises.
Champaign, IllinoisAges 50–90 - NCT03545477Recruiting
Curved walking training for stroke, Parkinson's and hip fracture recovery
This study tests whether practicing walking in curved paths can help people recovering from a stroke, Parkinson's disease, or a recent hip fracture improve their balance and mobility. If you have one of these conditions and are in a rehabilitation program, this training might make everyday walking easier.
Lissone, Monza E BrianzaAges 18–90 - NCT03019757Recruiting
Testing ways to tell dementia causes apart
This study looks at how to distinguish Alzheimer’s disease, Lewy body dementia, and Parkinson’s disease when someone has memory and thinking problems. It may help doctors choose the most accurate diagnosis and treatment path for the right condition.

Study of IPX-203 for Parkinson's disease (BOOST-PD)
This study tests a new formulation of carbidopa-levodopa (IPX-203) to see how well it works for people with Parkinson's disease. It uses a wearable device to measure movement and aims to improve “off” time, when symptoms return between doses.
Cleveland, OhioAges 40 years+ - NCT06586320Enrolling by invitation
Eye movement test for Parkinson's and Essential tremor
This study uses a simple eye movement test to see if it can help tell the difference between Parkinson's disease, Essential tremor, and healthy people. The goal is to find a better way to diagnose and track these conditions.
Manchester, New HampshireAges 18 years+ - NCT04616508Recruiting
Online arm movement training for people with Parkinson’s

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.
