Diabetic Retinopathy clinical trials in California
We’re tracking 9 recruiting diabetic retinopathy studies with a site in California — including Phase 1, Phase 2, Phase 2/Phase 3 and Phase 3 studies, each written for real people, not researchers.
Recruiting studies in California
- 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.
Bakersfield, CaliforniaAges Any age - NCT07588100RecruitingPhase 1
Safety study of RO7663498 eye injection for diabetic retinopathy
This is an early-stage safety study testing a new medicine injected directly into the eye to treat diabetic retinopathy (damage to blood vessels in the retina caused by diabetes). The study checks if the medicine is safe and how the body processes it.
Glendale, 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+ - NCT06770933RecruitingPhase 2
VX-01 pill for diabetic eye disease study
This trial tests if an oral medication called VX-01 can help people with diabetic eye disease (non-proliferative diabetic retinopathy) that is moderate to severe but not yet at the most advanced stage. It may be an option if you have type 1 or type 2 diabetes and have not had certain prior eye treatments.
Santa Barbara, CaliforniaAges 18 years+ - NCT06837181Recruiting
Understanding diabetes complications in cystic fibrosis
This study looks at how long-term diabetes affects people with cystic fibrosis. It helps researchers understand complications and improve care.
Los Angeles, CaliforniaAges 12 years+ - NCT06790784RecruitingPhase 3
Comparing faricimab plus laser vs. surgery for diabetic eye disease
This study compares two approaches to treat advanced diabetic eye disease (proliferative diabetic retinopathy): injections of faricimab plus laser, versus surgery (vitrectomy) with laser. It is for people with diabetes who need treatment for PDR and still have relatively good vision (20/100 or better) in the affected eye.
Huntington Beach, CaliforniaAges 18 years+ - NCT03752840Recruiting
Community eye-worker program in Nepal
This trial tests a village-based approach to bring eye care closer to older community members. If you live in the right area and are willing to participate, it may help improve access to eye screening and services.
San Francisco, CaliforniaAges 60 years+ - NCT07354477RecruitingPhase 2
New eye drop for glaucoma and diabetic retinopathy
This trial tests a new eye drop (QLS-111) to see if it improves blood flow in the back of the eye. It may help people with mild to moderate glaucoma or stable diabetic retinopathy by reducing pressure inside the eye and nourishing the optic nerve.
Palo Alto, CaliforniaAges 18 years+ - NCT06943599Recruiting
Improving Eye Care After Screening
This study looks at better ways to help people get follow-up eye care after a screening. If you were in the VIEW II study and were referred to an eye hospital, this trial may offer strategies to support you in getting that care.

What taking part in a diabetic retinopathy 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 diabetic retinopathy clinical trials in California?
- Yes. We're currently tracking 9 recruiting diabetic retinopathy 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 diabetic retinopathy 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 diabetic retinopathy 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 diabetic retinopathy 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.
