Recruiting studies in California
- NCT06783309RecruitingPhase 1/Phase 2
Testing CNP-103 for newly diagnosed type 1 diabetes
This trial tests a new study drug called CNP-103 for people ages 12-35 who were recently diagnosed (within 6 months) with stage 3 type 1 diabetes. The goal is to see if the drug can help preserve the body's ability to make some insulin, potentially slowing the need for more insulin shots.

Blood test study to track markers in diabetes
This study measures “circulating biomarkers” (blood-based signals) in people with type 1 or type 2 diabetes, and in some people without diabetes who test positive for certain diabetes antibodies. The goal is to understand what these blood signals can tell us about diabetes development and progression.
Duarte, CaliforniaAges Any age - NCT04933851RecruitingPhase 2

Duarte, CaliforniaAges 18–65 - NCT02734277Recruiting
Extending a past Type 1 diabetes immune study
This study is for people who already took part in an earlier immune-tolerance program for Type 1 diabetes. It tests whether continuing follow-up and assessments can be done safely and may help learn more about long-term immune effects of treatment.
San Francisco, CaliforniaAges 8–35 - NCT07282639Recruiting
App-based diabetes education for type 1 diabetes
This study tests an app-based diabetes education program for people with type 1 diabetes. It aims to see if the app can help you manage your blood sugar levels better using insulin pens and a continuous glucose monitor.
Los Angeles, CaliforniaAges 18 years+ - NCT06883344Recruiting
Automated insulin for managing blood sugar during labor
This study tests if an automated insulin delivery system can help manage blood sugar levels during labor and delivery in pregnant women with type 1 diabetes. If successful, it could make the process safer and easier.
Los Angeles, CaliforniaAges 18–55 - NCT06654713Recruiting
Closed-loop insulin system impact on pregnancy study
This study looks at how automated insulin delivery systems (closed-loop pumps) work during pregnancy for women with type 1 diabetes. It aims to understand how these systems can help manage blood sugar levels safely for both you and your baby.
San Francisco, CaliforniaAges 18 years+ - NCT07546929RecruitingPhase 2
HP-211 Safety Study for Type 2 Diabetes Treatment
This study tests a new medicine called HP-211 in people with early-stage type 2 diabetes to see if it's safe and helps control blood sugar. You'd take the study drug along with your current diabetes management.

Fully Closed Loop Insulin Pump for Type 2 Diabetes
This study tests a new automated insulin pump system (Omnipod) that adjusts insulin doses on its own throughout the day for people with type 2 diabetes. The goal is to see if it helps keep blood sugar levels more stable while reducing the burden of manual insulin management.
Newport Beach, CaliforniaAges 18–75 - NCT05322213RecruitingPhase 1
THC study for blood sugar control in type 2 diabetes
This early-phase study tests how THC (the main cannabis ingredient) affects blood sugar levels in people with type 2 diabetes. It may help researchers understand whether THC changes glucose control and what risks come with it.
La Jolla, CaliforniaAges 21–70 - NCT07662109RecruitingPhase 3
Testing a new combo pill for type 2 diabetes
This study tests if a new medicine (elecoglipron) combined with dapagliflozin is safe and works better for adults with type 2 diabetes that isn't well controlled by diet or other medications.
Bakersfield, CaliforniaAges 18 years+ - NCT07662044RecruitingPhase 3
Studying elecoglipron for type 2 diabetes

What taking part in a type 1 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 type 1 diabetes clinical trials in California?
- Yes. We're currently tracking 89 recruiting type 1 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 type 1 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 type 1 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.
