Aurora, ColoradoAges 18–80 - NCT07229651RecruitingPhase 2/Phase 3
Metformin for Parkinson's disease
This trial tests if metformin, a diabetes drug, can help people with Parkinson's disease. It may improve symptoms or slow progression.
TantaAges 50–70 - NCT07226284Recruiting
Testing a nerve stimulation device for leg movement in Parkinson's
This study tests if a device that stimulates the vagus nerve (a nerve in your neck) can improve leg muscle activity and walking balance in people with Parkinson's disease. You would participate in experiments while wearing the device to see how it affects your movement.
Minneapolis, MinnesotaAges 21–76 - NCT07217054Recruiting
Parkinson's and RBD diagnosis via colon biopsy
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.
Branford, ConnecticutAges 40–99 - NCT07204652Recruiting
Colonoscopy test for Parkinson's disease detection
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.
Portland, OregonAges 40–99 - NCT07207096Recruiting
Study of complementary medicine for Parkinson's disease
This study looks at patients with Parkinson's disease who visit a clinic that offers complementary medicine (like natural therapies). It aims to learn more about their experiences and health outcomes.
LondonAges 18 years+ - NCT07190404Recruiting
Thinking skills program for Parkinson's disease
This study tests a program to help people with Parkinson's disease who are noticing problems with their memory or thinking. The program teaches strategies to manage daily thinking challenges.
St Louis, MissouriAges 50 years+ - NCT05778617RecruitingPhase 3
Ambroxol to Slow Parkinson’s Disease Progression
This trial studies whether ambroxol (or a placebo) can slow the progression of Parkinson’s disease. It may help by aiming to change how the disease develops over time.
BirminghamAges 35–75 - NCT07154511RecruitingPhase 1/Phase 2
Tributyrin for Parkinson's with memory problems
This trial tests a supplement called tributyrin to see if it can help with thinking and memory problems in people with Parkinson's disease. You may be able to join if you have both Parkinson's and mild cognitive impairment or dementia.
Ann Arbor, MichiganAges 45 years+ - NCT06859528Recruiting
Walking program for people with Parkinson's disease
This study tests a community-based walking program designed for people with Parkinson's disease. It aims to see if regular walking can help improve movement and overall well-being.
St Louis, MissouriAges 30–85 - NCT07026734Recruiting
Speech and Swallow Effects of Deep Brain Stimulation in Parkinson's
This study looks at how deep brain stimulation (DBS) affects speech and swallowing in people with Parkinson's disease. It aims to help understand changes so doctors can better support you after DBS surgery.

Study of a new Parkinson's injection and quality of life
This study is looking at how a new continuous 24-hour injection treatment (foslevodopa/foscarbidopa) affects quality of life in people with advanced Parkinson's disease. It is a real-world study, meaning you just take the medication as your doctor prescribes, and researchers observe the results.
Troina, EnnaAges 18 years+ - NCT06588439Recruiting

Common questions
- Are there clinical trials for parkinson’s disease?
- Yes. Clin2 currently lists 722 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.
