Lake Forest, CaliforniaAges 18–75 - NCT07579702Recruiting
Omnipod 6 Versus Omnipod 5 Insulin Pump System
This study compares two versions of the Omnipod insulin pump system to see if the newer Omnipod 6 works better at managing blood sugar than the current Omnipod 5. You'll wear one of these systems for several months and share data about how well it helps control your diabetes.
Los Angeles, CaliforniaAges 14–75 - NCT07521475Recruiting
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.
Los Angeles, CaliforniaAges 18–75 - NCT07724340RecruitingPhase 2
Study of AT673 plus semaglutide for type 2 diabetes and weight loss
This study tests a new medication called AT673 combined with semaglutide (Wegovy) to help people with type 2 diabetes and overweight or obesity lose weight and improve blood sugar. It is for people who have tried diet and exercise to lose weight but haven't had success.
Anaheim, CaliforniaAges 18 years+ - NCT07465224RecruitingPhase 2
Study of ALN-4324 on Insulin Sensitivity in Type 2 Diabetes
This study tests an experimental drug, ALN-4324, to see if it can improve how your body responds to insulin. It’s for adults with type 2 diabetes who are already on certain diabetes medications and have stable blood sugar control.
Chula Vista, CaliforniaAges 18–65 - NCT03460769Recruiting
Mixed meal test to study diabetes from pancreas conditions
This study uses a special blood-sugar test (a mixed meal) to better diagnose and understand diabetes related to pancreatic cancer or chronic pancreatitis, and to compare it with other diabetes types. It may help researchers find clearer ways to tell these diabetes causes apart and understand how they work.
Los Angeles, CaliforniaAges 30–84 - NCT03746769RecruitingPhase 1/Phase 2
Testing gastrin to improve results of islet cell transplant
This trial looks at whether adding gastrin can improve outcomes after an islet cell transplant for people with type 1 diabetes. It may help some participants achieve better blood sugar control, but it also requires close follow-up and immune-suppressing medications to protect the new cells.
Duarte, CaliforniaAges 18–68 - NCT04141878Recruiting
Lifestyle program to help prevent dementia in adults with diabetes risk
This trial tests a structured lifestyle program (more activity and healthier eating) to help prevent or slow memory and thinking problems. It may be helpful if you’re older but not showing major memory impairment, and you can commit to weekly study activities for about 8 months.
Walnut Creek, CaliforniaAges 60 years+ - NCT04428658Recruiting
Telehealth coaching for kids to improve blood sugar control
This trial tests whether extra diabetes coaching delivered through online video and online messages can lower blood sugar levels in children with type 1 diabetes. It may help your child improve diabetes control by combining real-time and non-real-time support.
Sacramento, CaliforniaAges 5–18 - NCT04783441Recruiting
Continuous glucose sensor study after kidney transplant
This study checks whether using a continuous glucose monitor (a sensor that tracks sugar throughout the day) is helpful and practical for people with a recent kidney transplant and type 2 diabetes on insulin. You may need to wear the sensor continuously and still do finger-stick glucose checks for safety.
Sacramento, CaliforniaAges 18 years+ - NCT04786262RecruitingPhase 3
Study of VX-880 for long-standing type 1 diabetes
This Phase 3 trial tests how safe, tolerable, and effective VX-880 is for people with type 1 diabetes who have had it for many years. It may help reduce problems related to blood sugar swings, especially severe low blood sugar episodes.

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.
Not the right time?
New diabetes studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
