Recruiting studies in California
- NCT05369052RecruitingPhase 3
New antibiotic for moderate or severe diabetic foot infections

La Jolla, CaliforniaAges 21–70 - NCT05279729Recruiting
Mobile app coaching for people with diabetes
This study tests whether using a smartphone app can help people with type 2 diabetes manage their health. It focuses especially on low-income Hispanic/Latinx adults who regularly check blood sugar.
San Diego, CaliforniaAges 18–64 - NCT05296447Enrolling by invitationPhase 2
Long-term safety study for diabetic retinopathy gene therapy
This study follows people who already received an injection of RGX-314 (an experimental gene therapy) in a previous clinical trial for diabetic retinopathy, with or without swelling in the macula. It checks the long-term safety and how the treatment works over time.
Beverly Hills, CaliforniaAges Any age - 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
A study of VX-880 and VX-017 for type 1 diabetes
This study tests two investigational drugs, VX-880 and VX-017, for people with type 1 diabetes who have trouble controlling their blood sugar and have frequent severe low blood sugar episodes. The goal is to see if these drugs can improve blood sugar control and reduce dangerous lows.
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.

Study of BI 1815368 for diabetic macular edema
This study tests a new medicine, BI 1815368, to see if it can help people with diabetic macular edema, a condition that causes swelling in the back of the eye and can blur vision. If you qualify, you may be able to try this treatment and help researchers learn if it works.
Arcadia, CaliforniaAges 18 years+ - NCT04684602RecruitingPhase 1/Phase 2
Study of stem cells for several short- and long-term illnesses
This early-stage study tests whether injections of mesenchymal stem cells can be safe and helpful for certain chronic (long-term) and acute (short-term) conditions. You might be considered if you can consent, are able to return for follow-up visits, and do not have key reasons that would make stem-cell treatment unsafe.
Culver City, CaliforniaAges 18 years+ - NCT05588583Recruiting
Tracking drainage from chronic leg or foot ulcers with a dressing

Castro Valley, CaliforniaAges 18 years+ - NCT07807280Recruiting
Learning carb counting with a continuous glucose monitor
This study tests a new way to learn carb counting using a continuous glucose monitor (CGM). It may help you improve your blood sugar control without needing more injections.
Los Angeles, CaliforniaAges 18 years+ - NCT07784725RecruitingPhase 3
Study of a weight loss injection for adults with obesity
This study tests a new medicine to help adults with obesity or overweight lose weight. It's for people who have had trouble losing weight in the past and don't have diabetes.
Escondido, CaliforniaAges 18 years+ - NCT07783802RecruitingPhase 2
Study of clazakizumab for adults with high inflammation and heart risk
This study tests whether clazakizumab can reduce the risk of heart attacks or strokes in people with high levels of inflammation (measured by a blood test called hsCRP) and conditions like heart disease, obesity, diabetes, high blood pressure, or kidney disease. If you qualify, you'll receive either the study drug or a placebo to see if it helps lower your risk.
Glendora, CaliforniaAges 18 years+ - NCT07734844RecruitingPhase 3
New vs existing treatment for diabetic macular edema
This study compares a new medication, tabirafusp tedromer, to an existing treatment, aflibercept, for people with diabetic macular edema (swelling in the back of the eye from diabetes). It may help if your DME hasn't improved or you're looking for a new option.
Glendale, CaliforniaAges 18 years+ - NCT05708859RecruitingPhase 4
Tirzepatide to slow plaque buildup in coronary arteries
This trial studies tirzepatide to see if it can slow the progression of coronary artery plaque in people with type 2 diabetes. It uses special heart CT scans to track changes over time.
Torrance, CaliforniaAges 40–80 - NCT07701590Recruiting
New wound dressings for hard-to-heal leg and foot ulcers
This study tests a special amniotic membrane wound dressing compared to a synthetic wound matrix for stubborn diabetic foot ulcers or venous leg ulcers. It may help if your wound has not been healing well for over a month.
San Diego, CaliforniaAges 18 years+ - NCT07685808RecruitingPhase 2
Testing a weight loss injection for people with overweight or obesity
This study tests an injectable medication called Olatorepatide to help people with overweight or obesity lose weight. It is only for people without diabetes who meet specific body mass index (BMI) requirements.
Walnut Creek, CaliforniaAges 18 years+ - NCT07684144RecruitingPhase 3
Long-term study of a weight-loss medication for people who completed an earlier trial
This study tests the long-term effects of a medication called maridebart cafraglutide for weight management. It is for people who already completed a 72-week study of this drug and want to continue treatment.
Canoga Park, CaliforniaAges 18–99 - NCT05165706Recruiting
Study of how obesity affects insulin resistance over time
This study follows adults over time to understand how weight and body chemistry relate to insulin resistance. It may help researchers learn why insulin resistance happens and what could prevent or improve it.
Stanford, CaliforniaAges 35–65 - NCT07565506RecruitingPhase 2
Nu-3 Gel for Mild Diabetic Foot Infections
This study tests a new gel treatment (Nu-3) for mild infections in diabetic foot ulcers. The goal is to find the right dose and see if it helps heal these wounds safely.
Los Angeles, CaliforniaAges 18 years+ - NCT07478263Recruiting

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.
Clin2 helps you find and understand clinical trials and does not provide medical advice. Study data comes from ClinicalTrials.gov. Talk with your doctor about whether a specific trial is right for you.
