Recruiting studies
- NCT03264352RecruitingPhase 4

This study looks at how genetic risk relates to developing type 2 diabetes, using information from a biobank and body measurements like weight. It may help researchers better identify who is at higher risk before diabetes starts.
Philadelphia, PennsylvaniaAges 10–70 - 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 - NCT04451915Recruiting

Duarte, CaliforniaAges 18–65 - NCT04874012RecruitingPhase 2
Taurine supplement study for blood sugar, fats, and inflammation
This Phase 2 study tests whether taking taurine affects blood sugar control, cholesterol/fats, and inflammation in people with type 2 diabetes. It may help by improving these lab markers, which are linked to long-term health risks.
Porto Alegre, Rio Grande do SulAges 30–80 - NCT05026723Recruiting
Food plan to improve health for HIV and type 2 diabetes
This study tests whether a personalized “food as medicine” approach can help people manage health related to HIV and type 2 diabetes or prediabetes risk. If you struggle with having enough healthy food, the program may focus on practical ways to improve diet and support healthier blood sugar.
Chapel Hill, North CarolinaAges 18 years+ - NCT05124457RecruitingPhase 2
Detemir vs NPH insulin for diabetes in pregnancy
This Phase 2 study compares two types of insulin—insulin detemir vs NPH—to see which works better and is safe for controlling blood sugar during pregnancy. You may be invited if you are pregnant and need insulin for either pre-existing type 2 diabetes or gestational diabetes.
Los Angeles, CaliforniaAges 18 years+ - NCT05269589Recruiting
Home heat therapy for people with type 2 diabetes
This trial tests whether using heat therapy at home can improve health in adults with type 2 diabetes. It may help people who already have stable diabetes treatment, but it is not for everyone, especially if certain heart, nerve, or vision problems are present.
Montreal, QuebecAges 45–75 - NCT05317455RecruitingEarly Phase 1
Studying brain sugar changes in adults with risky low blood sugar
This early-stage study looks at how the brain uses sugar in people with type 1 diabetes who have had severe or hard-to-notice low blood sugar. It may help researchers understand the brain effects of low blood sugar and guide safer care.
New Haven, ConnecticutAges 18–55 - NCT05420051Recruiting
Program to boost happiness and emotional well-being in type 2 diabetes
This trial tests whether a support program using messages and coaching can improve emotional well-being and happiness for people with type 2 diabetes. It may also encourage healthier activity, especially if you’re currently not very active.
Boston, MassachusettsAges 18 years+ - NCT05585983RecruitingPhase 4
Flu shot in newly diagnosed type 1 diabetes patients
This trial checks whether giving a flu vaccine to people who were just diagnosed with type 1 diabetes affects their health and immune response. It may help doctors understand if flu vaccination is safe and useful soon after diagnosis.
AalborgAges 7–17 - NCT05594706Recruiting
Anhydroglucitol test in children with type 1 diabetes
This trial studies how anhydroglucitol behaves in children with type 1 diabetes who use insulin pump therapy and glucose monitoring. Your team will compare measurements over about a year to see if this marker could be useful for tracking diabetes control.
Geneva, Canton of GenevaAges 2–18 - NCT05598203Recruiting
Nutrition education groups for adults with type 2 diabetes
This trial studies whether attending group sessions about nutrition can help adults with type 2 diabetes manage their health better. It may be most helpful if your diabetes is not yet well controlled and you can safely participate in group education.
Porto Alegre, Rio Grande do SulAges Any age - NCT05605704RecruitingPhase 2/Phase 3

Diabetes and a new drug-free heart stent after angioplasty
This trial tests whether a polymer-free amphilimus-eluting stent is safe and works well for people with diabetes after a recent heart blockage procedure. It may help improve how well the artery stays open, while tracking side effects over time.
SeoulAges 19 years+ - NCT05780905RecruitingPhase 4
Semaglutide study for brain blood flow in type 2 diabetes
This trial tests whether semaglutide changes blood flow in the brain and the brain’s “barrier” (how well the brain is protected) in people with type 2 diabetes. It may help researchers understand brain-related effects of diabetes treatment using scans and blood tests.
Seattle, WashingtonAges 40–65 - NCT05899166Recruiting
Diet study to improve blood sugar control in new diabetes
This study looks at how carbohydrate intake may affect how well insulin-producing cells work and how stable your blood sugar becomes in children with newly diagnosed type 1 diabetes. It may help families learn dietary steps that improve glucose control early on.
Boston, MassachusettsAges 5–12 - NCT05958368Recruiting

- Yes. Clin2 currently lists 886 recruiting diabetes mellitus 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 mellitus 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 mellitus 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.
