Lincoln, CaliforniaAges 18 years+ - NCT07592273RecruitingPhase 2/Phase 3
Gene therapy for diabetic eye disease without macular swelling
This trial tests a gene therapy injection into the eye to treat diabetic retinopathy (eye damage from diabetes) before it progresses. The goal is to slow or prevent vision loss and potentially delay the need for laser treatment or other injections.
Bakersfield, CaliforniaAges 18 years+ - NCT07518004Recruiting
ROME GS System Study for diabetes glucose monitoring
This study tests the ROME GS System, a glucose monitoring device that measures blood sugar levels. The system includes a sensor placed under the skin and a transmitter worn on the body. If you have diabetes and want to help evaluate a new way to track your blood sugar, this trial may be for you.
Escondido, CaliforniaAges 18 years+ - NCT06550596Recruiting
Amnion membrane for diabetic foot ulcers
This trial tests a wound covering made from donated amniotic tissue (dehydrated human amnion membrane) placed on a diabetic foot ulcer that isn't healing. It aims to see if adding this membrane to standard wound care helps the ulcer close faster.
Thousand Oaks, CaliforniaAges 18 years+ - NCT07449039Recruiting
Blood sugar tracking after pregnancy for diabetes risk
This study uses a continuous glucose monitor to track blood sugar for 2 weeks after delivery in women who had gestational diabetes. The goal is to better understand who develops type 2 diabetes later and help prevent it.
Los Angeles, CaliforniaAges 18 years+ - NCT07386340Recruiting
Testing a new continuous glucose monitor with flash readings

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 188 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?
