What taking part in a adolescent 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.

Common questions
- Are there adolescent clinical trials in California?
- Yes. We're currently tracking 109 recruiting adolescent studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.

- Do I have to live in California to take part?
