Los Angeles, CaliforniaAges Any age - NCT06524960RecruitingPhase 1/Phase 2
Denosumab for Preserving Insulin in Type 1 Diabetes
This study tests if denosumab, a drug normally used for bone health, can help preserve your body's own insulin production in type 1 diabetes. It might slow the loss of insulin-making cells, helping you maintain better blood sugar control over time.
Duarte, CaliforniaAges 18–50 - NCT06525259Recruiting
Study on risk factors for type 2 diabetes in youth
This study looks for children and teens who are at high risk of developing type 2 diabetes to understand what factors lead to it. If your child is overweight, has slightly high blood sugar, and is in early to mid-puberty, they may be able to join.

What taking part in a diabetes 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 diabetes clinical trials in California?
- Yes. We're currently tracking 189 recruiting diabetes studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a diabetes study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a diabetes trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
