Each trial is sourced daily from ClinicalTrials.gov and translated for families with a five-word goal and a plain-language summary. The live California list at [https://parkinsonspathways.com/trials-near-me/california](https://parkinsonspathways.com/trials-near-me/california) shows every recruiting study with a research site anywhere in the state.

Enter your city, zip code, or postcode and a search radius. Parkinson's Pathways finds every recruiting Parkinson's trial with a study site inside that radius, sorted by distance. Each result links to a family-friendly summary, a five-word goal, and the site contact details. ### Are these Parkinson's clinical trials free to join? Yes. There is no cost to participate in a clinical trial. Study-related care, treatment, and assessments are paid for by the trial sponsor. Some trials also reimburse travel, parking, and lodging when the site is far from your home. ### How far should I be willing to travel for a Parkinson's trial? Most participants travel between 25 and 50 miles for routine visits. For a high-priority disease-modifying trial, families sometimes travel further, especially because some early-phase trials only run at a handful of academic medical centers. Many sites help with travel costs when the distance is significant. ### Who runs these clinical trials? Parkinson's clinical trials are run by academic medical centers, university hospitals, pharmaceutical companies, biotech startups, and patient foundations like The Michael J. Fox Foundation. Every trial listed here is registered with the U.S. National Library of Medicine on ClinicalTrials.gov. ### How often are the local trial listings updated? Every day. The full list refreshes from ClinicalTrials.gov each morning, so a trial that started recruiting yesterday will appear today. Trials that stop recruiting are removed automatically. ### Do I need a Parkinson's diagnosis to enroll in a local trial? Most trials require a confirmed Parkinson's diagnosis from a neurologist, but some recruit healthy volunteers as a comparison group, and a few recruit people at risk for Parkinson's based on family history or early symptoms. Each trial's eligibility section spells out who can join. ### What if there are no Parkinson's trials near my city right now? Try increasing the search radius to 100 or 250 miles, or sign up for the free weekly digest. Spencer sends a Monday email summarizing every new recruiting Parkinson's trial, so you can catch one the day it opens near you. ## Trials in other cities - [San Francisco, California](https://parkinsonspathways.com/trials-near-me/san-francisco) - [Los Angeles, California](https://parkinsonspathways.com/trials-near-me/los-angeles) - [San Diego, California](https://parkinsonspathways.com/trials-near-me/san-diego) - [Boston, Massachusetts](https://parkinsonspathways.com/trials-near-me/boston) - [New York, New York](https://parkinsonspathways.com/trials-near-me/new-york) - [Philadelphia, Pennsylvania](https://parkinsonspathways.com/trials-near-me/philadelphia) - [Baltimore, Maryland](https://parkinsonspathways.com/trials-near-me/baltimore) - [Washington, DC, District of Columbia](https://parkinsonspathways.com/trials-near-me/washington-dc) - [Atlanta, Georgia](https://parkinsonspathways.com/trials-near-me/atlanta) - [Miami, Florida](https://parkinsonspathways.com/trials-near-me/miami) - [Tampa, Florida](https://parkinsonspathways.com/trials-near-me/tampa) - [Orlando, Florida](https://parkinsonspathways.com/trials-near-me/orlando) - [Charlotte, North Carolina](https://parkinsonspathways.com/trials-near-me/charlotte) - [Raleigh-Durham, North Carolina](https://parkinsonspathways.com/trials-near-me/raleigh-durham) - [Nashville, Tennessee](https://parkinsonspathways.com/trials-near-me/nashville) - [Chicago, Illinois](https://parkinsonspathways.com/trials-near-me/chicago) ## Related - [Search by your own city or zip code](https://parkinsonspathways.com/trials-near-me) - [Browse all 503 recruiting Parkinson's trials](https://parkinsonspathways.com/trials)
