Recruiting studies
- NCT07557706RecruitingPhase 1
Vagus Nerve Stimulation to Improve Heart Function in Parkinson's Disease
This study tests a non-invasive ear-based stimulation technique (taVNS) to help regulate heart function in people with Parkinson's disease. The goal is to see if this gentle stimulation can improve blood pressure and heart rate control.
Birmingham, AlabamaAges 18–80 - NCT06687837RecruitingPhase 1
Stem cell therapy for Parkinson's disease
This trial tests whether implanting your own stem cells (made into dopamine-producing brain cells) can improve Parkinson's motor symptoms. You would need to be a candidate for brain surgery and have a stable medication routine.
Boston, MassachusettsAges 45–80 - NCT06080659Recruiting
Brain network study for Alzheimer's and Parkinson's
This study uses brain scans to look for patterns that might help diagnose memory or movement problems like Alzheimer's or Parkinson's disease. It compares people with mild symptoms, like forgetfulness or early Parkinson's, to healthy volunteers.
RennesAges 50–80 - NCT04720365Recruiting
Home video game rehab to help Parkinson’s walking and balance
This trial tests whether a serious (therapeutic) home video-game program can improve walking and balance problems for people with Parkinson’s disease who still have trouble even with levodopa. It also looks at whether the approach is worth it in real-world care (cost and benefits).
BordeauxAges 18 years+ - NCT06814431Recruiting
Cancer risk in parkinson's patients with GBA gene mutation
This study looks at whether people with Parkinson's disease who have a specific gene change (GBA mutation) have a higher chance of developing cancer. It will help doctors understand the link between these conditions.
BrindisiAges 18 years+ - NCT06145711Recruiting
Stem cell therapy for Parkinson's disease
This trial uses special stem cells (made from skin or blood cells) to replace damaged brain cells in people with Parkinson's. The goal is to see if these cells can improve movement and reduce symptoms.
Shanghai, Shanghai MunicipalityAges 30–70 - NCT06232772Recruiting
Biomarkers for early Parkinson's diagnosis
This study looks for new markers in the blood or other samples to help diagnose Parkinson's disease earlier. It compares people with Parkinson's, related conditions (like multiple system atrophy or progressive supranuclear palsy), and healthy volunteers to find differences.
Nanning, GuangxiAges 18–80 - 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+ - NCT05539196Recruiting
Registry for Exablate treatment in Parkinson’s with medication problems
This trial is a real-world registry that follows people with Parkinson’s who are planning to get an Exablate 4000 procedure (a focused ultrasound treatment) for one-sided symptoms that are difficult to control with medication. It mainly checks outcomes and safety over time, helping doctors understand how well this treatment works in everyday care.
Baltimore, MarylandAges 30–99 - NCT06008704Recruiting
PET scan study of pain in Parkinson's disease
This study uses a special brain scan (PET) to look at the serotonin system in people with Parkinson's who have chronic pain. The goal is to understand why some people feel pain and how the brain chemical serotonin might be involved.
Toulouse, Haute-GaronneAges 40–80 - NCT06582212Recruiting
Managing Hormonal Triggers in Women with Parkinson's
This study helps women with Parkinson's disease who are still having periods learn how hormonal changes may affect their symptoms. You will be guided to identify and manage these triggers better.
Grenoble, GrenobleAges 18–56 - NCT07278297Enrolling by invitation
Parkinson ballroom fitness: dance for better movement and mood
This study tests whether personalized ballroom dancing can help improve both motor (movement) and nonmotor (mood, thinking) symptoms in people with Parkinson's. You would attend dance classes and testing sessions, possibly with a caregiver or family member.
Viborg, Central JutlandAges 40 years+ - NCT05843084Recruiting
7-Tesla brain scans to map networks for Parkinson’s DBS
This study uses a very strong MRI (7-tesla) to analyze how parts of the brain connect in people with Parkinson’s who already have deep brain stimulation (DBS). It may help researchers better understand DBS and how it works in the brain.
Amsterdam, North HollandAges 18 years+ - NCT07619560Recruiting
Probiotic Cocktail to Slow Early Parkinson's Disease
This study tests whether a special blend of probiotics (good bacteria), an amino acid called tryptophan, and branched-chain amino acids can help slow the progression of early-stage Parkinson's disease. The idea is that these supplements may work through your gut bacteria to help protect your brain.
TaipeiAges 30–85 - NCT06561919Recruiting
Speech and language study during brain stimulation treatment
This is an extra part of the STIMPulseControl study that focuses on speech. It looks at how the brain stimulation treatment affects your ability to speak clearly and communicate.
CologneAges 18–70 - NCT07687979Recruiting
Mobile app for walking training in Parkinson's disease
This trial tests whether a mobile phone app can help improve walking in people with Parkinson's disease. If you have mild to moderate Parkinson's and can use a smartphone, you may be able to join.
Izmir, İzmirAges 60–80 - NCT06848257Enrolling by invitation
Posture exercises for Parkinson's disease
This trial studies whether specific posture exercises can help people with Parkinson's disease improve their balance and movement. It is designed for people who are in the early to moderate stages of the disease and do not have other major health issues.
AnkaraAges 50 years+ - NCT06151002Recruiting
Remote assessment for people with Parkinson's
This trial tests a remote way to assess people newly diagnosed with Parkinson's disease, to help monitor their condition and guide care.
LondonAges 18–90 - NCT06425731Recruiting
Dance and energy in Parkinson's disease
This study looks at how dancing affects energy use in people with Parkinson's. If you already take Dance for PD® classes and have mild to moderate Parkinson's, researchers want to see how your body responds during a dance class.

Understanding meaningful hand function changes in Parkinson's
This study looks at a simple hand-and-arm test (the Box and Block Test) to see how much improvement matters to people with Parkinson's. It helps doctors understand what small changes in hand function are meaningful to you.
IstanbulAges 50–80 - NCT06848205Recruiting
Brain pacemaker study for freezing of gait in Parkinson's
This study looks at how a special brain pacemaker (called the Medtronic Percept device) affects walking problems like freezing of gait in people with Parkinson's. It aims to help understand and improve treatment.
Minneapolis, MinnesotaAges 21–75 - NCT07024875Recruiting
Brain imaging study for Parkinson's disease
This study uses brain scans to understand Parkinson's disease. It compares people with Parkinson's to healthy volunteers to learn how the brain changes.
St Louis, MissouriAges 40 years+ - NCT07176091Enrolling by invitation
Magnetic brain stimulation for Parkinson's disease pain
This trial tests a special type of magnetic brain stimulation (called TMS) to see if it can help with Parkinson's disease and the pain that often comes with it. You must have had Parkinson's for at least 3 years, have frequent pain, and be on stable medications.

Common questions
- Are there clinical trials for parkinson’s disease?
- Yes. Clin2 currently lists 740 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.
