Recruiting studies
- NCT05769699Recruiting
Blood test study for Parkinson’s stages
This study measures blood biomarkers (measurable substances in blood) in people with Parkinson’s at different stages. It may help doctors understand how Parkinson’s changes over time and could guide future testing or treatments.
RomaAges 18–80 - NCT06090682Recruiting
Brain stimulation for Parkinson's with thinking problems
This trial tests a brain stimulation technique (deep brain stimulation) to see if it can help people with Parkinson's disease who also have mild cognitive problems. The goal is to understand how stimulation affects both movement and thinking.
Tianjin, Tianjin MunicipalityAges Up to 75 years - NCT06237868Recruiting
TMS for Impulse Control in Parkinson's Disease
This trial tests whether a type of non-invasive brain stimulation called TMS can help reduce impulse control problems (like gambling or compulsive eating) that are caused by Parkinson's medications. It's for people with Parkinson's who are living with these side effects.
Morgantown, West VirginiaAges 18 years+ - NCT06316232RecruitingPhase 4
DBS and Levodopa for Freezing of Gait in Parkinson's
This trial tests whether increasing the dose of levodopa or adjusting deep brain stimulation (DBS) can help reduce freezing of gait in people with Parkinson's who already have good control of other symptoms. It aims to find the best way to manage this common and frustrating problem.
BolognaAges 18–80 - NCT06500182Recruiting
Horseback riding therapy for older adults with Parkinson's disease
This study tests if horseback riding therapy can help people with Parkinson's disease who are 75 or older. It aims to see if this gentle activity improves balance, walking, and quality of life.
Saint-Quentin, AisneAges 75 years+ - NCT06548256Recruiting
Probiotic for Parkinson's Symptoms
This trial tests whether a probiotic called Clostridium butyricum can help with both movement and non-movement symptoms of Parkinson's disease. It aims to see if improving gut health can ease symptoms.
Kaohsiung CityAges 20–90 - NCT06570421Recruiting
Nerve stimulation for Parkinson's and essential tremor
This study tests a non-invasive nerve stimulation device for reducing tremors in people with Parkinson's disease or essential tremor. It follows up participants from a previous trial to see if benefits last up to 24 months.
OstravaAges 18 years+ - NCT06588920Recruiting
Brain activity, thinking, and walking study for Parkinson's
This study looks at how brain activity relates to thinking and walking in people with Parkinson's disease. It may help understand the connections between these functions.
TaipeiAges 40–80 - NCT06798844RecruitingPhase 2
Spinal cord stimulation for freezing of gait in Parkinson's
This trial tests whether a spinal cord stimulator can reduce freezing of gait (feeling stuck when walking) in people with Parkinson's disease. It may help you if you have daily freezing episodes and are willing to have a small device implanted.
LeuvenAges 40–80 - NCT06909045Recruiting
Adaptive vs. regular deep brain stimulation for Parkinson's
This study compares two ways of using deep brain stimulation (DBS) — an adjustable ‘adaptive’ version that changes with your brain signals, versus the standard continuous setting. It aims to see which works better for people with Parkinson's disease who already have a specific type of DBS device.
LeuvenAges 18 years+ - NCT07097298Recruiting
Empathy and compassion study for Parkinson's patients and caregivers
This study explores empathy and self-compassion in people with Parkinson's disease and their caregivers. If you have mild to moderate Parkinson's and a caregiver at home, you and your caregiver may join together to help researchers understand how to better support both of you.
LuganoAges 50–80 - NCT07156773RecruitingPhase 2
Nasal spray for Parkinson's off episodes
This study tests a new nasal spray called XJN010 for people with Parkinson's who have 'off' episodes—times when their regular medication wears off and symptoms come back. The goal is to see if the spray can safely and effectively help during those periods.
Guangzhou, GuangdongAges 30–85 - NCT07679256Recruiting
Digital and brain markers for early Parkinson's diagnosis
This study uses digital tools and brain markers to detect Parkinson's disease early. It includes healthy people, those with early Parkinson's, and those with REM sleep behavior disorder (a possible early sign).
Fuzhou, FujianAges 40–80 - NCT07376278Recruiting
Deep brain stimulation outcomes in Parkinson's disease
This study looks at factors that predict how well deep brain stimulation (DBS) works for people with Parkinson's disease. If you are considering DBS, joining this research could help doctors better understand who benefits most from the procedure.
Hong KongAges 18–75 - NCT06285643RecruitingPhase 2
Gene therapy for moderate Parkinson's disease
This trial tests a gene therapy (AAV2-GDNF) to see if it can slow or improve symptoms of Parkinson's disease. It is for people who have had moderate Parkinson's for 4 to 10 years and still respond to levodopa therapy.
Phoenix, ArizonaAges 45–75 - NCT03021031Enrolling by invitation
Deep brain stimulation for Parkinson’s patients
This trial studies a type of brain stimulation to help reduce symptoms in people with Parkinson’s disease. You may be able to join if you have Parkinson’s and are being considered for this treatment.
Minneapolis, MinnesotaAges 21 years+ - NCT07382440Recruiting
Study of a Parkinson's treatment given under the skin
This study looks at how well a treatment called foslevodopa/foscarbidopa works for people with advanced Parkinson's disease. It is given as a shot under the skin (subcutaneous) and is already being used in clinics. The study will follow people who are already starting this treatment as part of their regular care.
Bonheiden, AntwerpenAges 18 years+ - NCT07386015Recruiting
Study of freezing of gait in Parkinson's disease
This study looks at people with Parkinson's disease or similar conditions who have walking problems like freezing of gait (feet feeling stuck) or balance issues. Researchers want to learn more about what causes these symptoms and how they affect people over time.
Tianjin, Tianjin MunicipalityAges 30–85 - NCT07202494Recruiting
Brain aging and resilience MRI study
This study uses powerful MRI scans to understand how the brain ages and why some people stay healthy while others develop neurological diseases like multiple sclerosis or Alzheimer's. It compares healthy volunteers to people with certain conditions, and all participants get a detailed brain MRI.
MarseilleAges 18–90 - NCT06916507Recruiting
Early Use of a Parkinson's Pump in Advanced Stages
This study tests a new pump-delivered combination of Parkinson's medications (foslevodopa/foscarbidopa) in adults who have recently started having motor fluctuations but are not yet using other device therapies. It aims to see how well it works in real life and may offer better symptom control.
Allensbach, Baden-WurttembergAges 18–64 - NCT06482268RecruitingPhase 1
Cell transplant for advanced parkinson's disease
This trial tests a new type of cell transplant for Parkinson's disease. The cells are made from stem cells and are meant to replace damaged brain cells that produce dopamine, which may improve your motor symptoms.
La Jolla, CaliforniaAges 40–75 - NCT06932679Recruiting
How people with Parkinson’s cross obstacles
This study looks at how people with and without Parkinson’s disease see and step over obstacles while walking. It aims to understand differences in perception and movement to help improve safety and mobility for people with Parkinson’s.
HaifaAges 20–80 - NCT04389437Recruiting

Common questions
- Are there clinical trials for parkinson’s disease?
- Yes. Clin2 currently lists 742 recruiting parkinson’s disease 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’s disease 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’s disease 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.
