Recruiting studies near San Jose
- NCT07174310RecruitingPhase 3
Prasinezumab for early Parkinson's disease
This study tests a new medication called prasinezumab, given through a vein (IV), to see if it can slow the progression of early-stage Parkinson's disease. It is for people who are on only one Parkinson's medication and have not yet developed motor complications.
Palo Alto, CaliforniaAges 50–85 - NCT06944522RecruitingPhase 3
Cell therapy for Parkinson's symptoms
This study tests a new cell therapy called bemdaneprocel to see if it can reduce Parkinson's symptoms and “off” time. The treatment involves transplanting special cells into the brain to help replace lost dopamine-producing cells.
Palo Alto, CaliforniaAges 45–75 - NCT06765668RecruitingPhase 4
Study of CREXONT for Parkinson's with wearing-off episodes
This study tests how well CREXONT, an extended-release form of carbidopa-levodopa, controls symptoms in people with Parkinson's who experience predictable 'off' periods when their regular medication wears off. The goal is to see if it can reduce the daily hours of poor mobility.
Palo Alto, CaliforniaAges 18 years+ - NCT07219927Recruiting
Patient experiences with pump-delivered Parkinson's drug
This study looks at real-world experiences of people with Parkinson's who are using ONAPGO, a medication given continuously under the skin through a pump. The goal is to understand how this treatment works in daily life.
Palo Alto, CaliforniaAges 18 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.
Palo Alto, CaliforniaAges 40 years+ - NCT06680830RecruitingPhase 2
Testing NEU-411 for early Parkinson's with LRRK2 gene change
This trial tests an experimental drug called NEU-411 for people with early Parkinson's disease who have a specific genetic change (LRRK2). It aims to see if the drug can slow the disease progression.
Palo Alto, CaliforniaAges 40–80 - NCT07432958RecruitingPhase 2
Study of AP-472 with levodopa for Parkinson's motor fluctuations
This trial tests an experimental drug called AP-472, taken alongside your regular Parkinson's medications, to see if it can reduce the amount of "OFF" time you experience each day when symptoms return between doses of levodopa.
Palo Alto, CaliforniaAges 30–80 - NCT05504902Enrolling by invitation
Device training for advanced Parkinson’s using touch feedback
This study tests whether coordinated touch (vibrotactile) training can improve symptoms in people with Parkinson’s. You may be asked to use a special device and attend virtual check-ins, with some visits requiring stopping Parkinson’s meds for short periods.
Stanford, CaliforniaAges 18 years+ - NCT07567794Recruiting
Gut-Brain Connection Study in Parkinson's Disease
This research examines how the gut and brain are connected in Parkinson's disease and aims to better understand the disease. You'd participate in visits and tests over three years, including some involving your digestive system.
Stanford, CaliforniaAges 21–80 - NCT05968703Recruiting
Deep brain stimulation study for mild memory trouble in Parkinson’s
This trial looks at a specific type of deep brain stimulation (DBS) to see if it can help people with Parkinson’s who have mild cognitive problems (mild memory/thinking changes). You may also be asked to temporarily stop Parkinson’s medications around research visits to measure effects more clearly.
Stanford, CaliforniaAges 21–80 - NCT05395624RecruitingPhase 1/Phase 2
Safety imaging study of a PET tracer in ALS, Alzheimer, MS, Parkinson
This early-phase study tests the safety of a radioactive tracer (“18F-OP-801”) and how the tracer moves through the body (biodistribution) in people with ALS, Alzheimer’s disease, multiple sclerosis, Parkinson’s disease, and in healthy volunteers. It also measures how the body processes the tracer (“pharmacokinetics”) to support future studies.
Stanford, CaliforniaAges 18–80 - NCT05826457Enrolling by invitation
Study for early RBD as a possible Parkinson’s risk
This study looks at people with REM sleep behavior disorder (RBD), confirmed by a sleep test, who may be in the early “prodromal” stage before Parkinson’s or related diseases. It also enrolls healthy controls to compare results from brain and body testing to better understand who is at risk.
Redwood City, CaliforniaAges 18 years+ - NCT03623672Enrolling by invitation
Study for early signs of Parkinson-related brain changes
This study enrolls people with idiopathic REM sleep behavior disorder, a sleep problem that can come before Parkinson’s disease or related conditions. It aims to better understand early (“prodromal”) changes so future treatments can be targeted earlier.
Redwood City, CaliforniaAges 18 years+ - NCT05292794Recruiting
CereGate therapy for freezing of gait in Parkinson’s
This trial tests whether CereGate therapy can reduce “freezing of gait,” a walking problem, in people with Parkinson’s disease who already have deep brain stimulation (DBS). If you meet the device and medication stability requirements, the study may help your walking and movement symptoms measured during testing.

What taking part in a parkinson’s disease study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
