Contact the research site through the registry page, complete a short phone screen, then attend an in-person screening visit.

You can withdraw at any point, and enrollment is always free.

Frequently asked questions

Do I need to be sick to join a clinical trial in Stockton?
No. Many studies recruit healthy volunteers, especially early-phase studies run at dedicated research centers. Others need participants diagnosed with a specific condition. Every trial lists its eligibility criteria — age range, condition, medications — and the study team screens you before enrollment.
Are clinical trials in Stockton safe?
Every trial on this page is registered on ClinicalTrials.gov, the official NIH registry, and is overseen by an Institutional Review Board (IRB). Before joining you receive an informed consent document detailing procedures, risks and compensation. Participation is voluntary and you can withdraw at any time.
How do I join a study in Stockton, CA?
Pick a study that matches your profile, contact the research site (or apply through the study links on this page), pass a phone pre-screen, then attend an in-person screening visit. If you qualify, you review and sign the informed consent and the study begins. The process typically takes 1-3 weeks.
What is the difference between a research center and a hospital study in Stockton?
Dedicated research centers (listed on this page with their Google ratings) run studies as their core business — often healthy-volunteer and vaccine studies with structured compensation. Hospital and university studies tend to focus on patients with specific conditions. Both types are registered and IRB-supervised.
Can I be in more than one clinical trial at a time?
Generally no — most studies exclude participants currently enrolled in another trial, and paid Phase 1 studies enforce a washout period (often 30 days or more) between studies. Frequent healthy volunteers in Stockton typically complete one or two studies per year.
