Recruiting studies
- NCT05681468Recruiting
Ketogenic diet trial for blood sugar and inflammation outcomes
This study compares two versions of a ketogenic (very low-carb) diet to see how they affect blood sugar control and inflammation. It may help people with overweight or obesity who have pre-diabetes-level blood sugar understand which fat sources work better.

Mobile, AlabamaAges 3–29 - NCT06988462Recruiting
Bottarga supplement for metabolic health
This study tests a supplement called bottarga, made from fish eggs, to see if it improves cholesterol, blood sugar, or weight in people with metabolic problems like high cholesterol or prediabetes. It is a small pilot study for Massachusetts residents.
Sommerville, MassachusettsAges 18–60 - NCT07317310Recruiting
Joint health and weight loss study for knee osteoarthritis patients

Eye scans study to compare brain and eye health
This study uses detailed eye imaging to look for patterns that may go along with conditions like Alzheimer’s disease, memory problems, multiple sclerosis, or eye/vascular issues. It may help researchers better understand how eye findings relate to health and disease.
Miami, FloridaAges 18–99 - NCT03228732RecruitingEarly Phase 1
Fluoxetine and/or DHEA in people with type 1 diabetes
This early-stage study tests whether the medicines fluoxetine and/or DHEA can improve health in adults with type 1 diabetes. It’s mainly looking for people without major diabetes complications or major medical problems to safely study the effects.
Baltimore, MarylandAges 18–50 - NCT03313024Recruiting
Pregnancy health study for common pregnancy blood sugar and pressure issues
This study follows pregnant people to better understand pregnancy complications like high blood pressure and gestational diabetes. You may be asked to provide regular health information and possibly samples to help researchers learn what affects you and your baby.
BerlinAges 18–45 - NCT03323216Recruiting
Testing heart-related blood markers in people with diabetes and heart failure
This study looks for blood markers that may help explain or predict heart problems in people who have type 2 diabetes and heart failure. To join, you may also need to be having a planned heart procedure where doctors can collect study information.
Aachen, North Rhine-WestphaliaAges 18 years+ - NCT03374215Recruiting
Study hormone causes of high blood pressure in Black adults
This study looks at the body’s hormone signals to understand what causes primary aldosteronism (a condition that can lead to high blood pressure). By comparing clinical results and lab data, researchers hope to improve how the condition is diagnosed and managed, especially in Black participants.
Bethesda, MarylandAges 7–70 - NCT03394313Recruiting
Registry study for people with new heart disease and type 2 diabetes
This study records health information to understand how type 2 diabetes and newly diagnosed heart disease affect people over time. It may help doctors learn what to watch for and how to plan care, though it is mainly an observational registry.
DohaAges 18 years+ - NCT03528226Recruiting
Exercise program to improve blood vessel function in type 1 diabetes
This trial studies whether an exercise training program can improve how well your blood vessels work in people with type 1 diabetes. It may help assess benefits beyond blood sugar control.
LilleAges 18–50 - NCT03540758RecruitingPhase 2
Study of how brain sugar control channels affect blood sugar
This Phase 2 study tests how certain channels in the brain help control how your body makes and releases sugar (glucose). It may help explain blood sugar problems in people with type 2 diabetes and healthy volunteers.
The Bronx, New YorkAges 21–70 - NCT03549559Recruiting
Heart imaging study in healthy people and specific conditions
This study uses heart imaging to look at changes in the heart muscle. It includes healthy volunteers and people with diabetes or aortic stenosis, to understand differences seen on scans.
Boston, MassachusettsAges 18–85 - NCT03568630Recruiting
Blood tests to study early pancreatic cancer risk
This study looks at blood “markers” to find early signs or higher risk for pancreatic cancer. You may join if you have certain risk factors (like new diabetes, pancreatic cysts/pancreatitis, or a strong family history) and can come to Omaha for blood draws twice a year.
Omaha, NebraskaAges 19 years+ - NCT03569735Recruiting
Elderly health survey in Nanshan, Shenzhen
This study follows people age 65 and older in Nanshan to learn about health over time using surveys and health samples. It may help researchers understand what supports healthy aging in the community.
Shenzhen, GuangdongAges 65 years+ - NCT03622359Recruiting
Imaging blood flow in leg artery disease using a scan
This study uses a special “radiotracer” scan to look at how well blood flows through the arteries in the legs. It may help researchers better understand circulation problems from peripheral artery disease.
Columbus, OhioAges 18 years+ - NCT03680794Recruiting
Testing a blood and eye-fluid marker in retinal disease
This study looks at a specific lab marker (sCD160) in blood and eye fluids to see how it relates to poor blood flow in the retina. You may be asked for samples taken during eye surgery to help doctors understand the disease better.
ReimsAges 18 years+ - NCT03710928Recruiting
Very low carbohydrate diet versus standard diet for type 1 diabetes
This study compares a very low carbohydrate diet to a regular diet to see how well blood sugar control works for adults with type 1 diabetes. It may help you understand which eating pattern is easier and safer for managing daily glucose with modern diabetes technology.
Boston, MassachusettsAges 18–40 - NCT03713268Recruiting
Using a scan to guide eye surgery in real time
This trial tests whether a special eye scan (OCT) can help guide eye surgery during the operation. It may improve how surgeons see and target the exact eye structures they need to treat.
Durham, North CarolinaAges 4 weeks+ - 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.

- Are there clinical trials for diabetes?
- Yes. Clin2 currently lists 2,208 recruiting diabetes studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a diabetes trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a diabetes trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
