How to enroll in a paid study in Antioch

Start with a study whose condition matches your profile — or a healthy-volunteer study if you have no diagnosis. Contact the research site through the registry page, complete a short phone screen, then attend an in-person screening visit. If you qualify, the study team walks you through the informed consent document, which details every procedure, risk and payment before you commit. You can withdraw at any point, and enrollment is always free.

Antioch participants can also register with the dedicated research centers listed above — many maintain volunteer databases and call when a matching study opens — or sign up for our email alert below to hear when a new study starts recruiting within 30 miles of your ZIP code.

Frequently asked questions

Do I need to be sick to join a clinical trial in Antioch?
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.
How do I join a study in Antioch, 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 Antioch?
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.
How often do new paid studies open in Antioch?
Constantly — trials open and close enrollment every week. This page is refreshed weekly from the NIH registry. Join the email alert to be notified when a new study opens within 30 miles of Antioch.
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 Antioch typically complete one or two studies per year.
