Ear stimulation, motivation, and insulin sensitivity in depression
This study explores how a gentle electrical stimulation of the ear might affect mood, motivation, and insulin sensitivity in people with and without depression. It aims to see if this non-invasive technique could offer new ways to help with depression.
BonnAges 18–60 - NCT06864546Recruiting
Diabetes glucose tracking study for people not on insulin
This study tests a new way to help people with type 2 diabetes track their blood sugar in everyday life. It aims to see if a simple, patient-friendly approach can improve glucose control without needing insulin.
Pavia, PaviaAges 40–70 - NCT07155252Recruiting
Home glucose test for type 1 diabetes screening
This study looks at whether you can do an oral glucose tolerance test at home instead of at a clinic. It is for people who have certain antibodies linked to type 1 diabetes or who were recently diagnosed with type 1 diabetes.
New Haven, ConnecticutAges 8–45 - NCT06958640Enrolling by invitation
Da Qing offspring health study

Glucose changes in cirrhosis patients around liver transplant
This study looks at how the body processes sugar (glucose) in people with cirrhosis who are waiting for a liver transplant. It aims to track changes in blood sugar control before and after transplant, which may help improve care for patients with liver disease.
Chicago, IllinoisAges 18–75 - NCT06942312Enrolling by invitation
Liver metabolism study in non-alcoholic fatty liver disease
This trial studies how the liver processes fat in people with non-alcoholic fatty liver disease (NAFLD). It uses MRI scans to look at liver metabolism, which may help doctors understand the disease better and find new treatments.
Helsinki, UusimaaAges 18–75 - NCT06876090Recruiting
Sarcopenia study in women with gestational diabetes
This trial looks at muscle health (sarcopenia) in women who had gestational diabetes during pregnancy. It aims to understand how gestational diabetes might affect muscle mass and function.
ViennaAges 35 years+ - NCT06867198Recruiting
Peanuts for heart, brain, and gut health
This study tests whether eating peanuts can improve health markers like blood sugar, brain function, and digestion in adults with prediabetes (higher than normal blood sugar levels). You may qualify if you are between 20-59 years old, have prediabetes, and a BMI in the overweight to obese range.

Lexington, KentuckyAges 35–65 - NCT04055428RecruitingPhase 2
Testing a hormone supplement to improve heart and metabolic health
This study tests whether adding a natriuretic peptide medicine improves heart health and metabolism in Black adults. It may help with blood pressure and related health markers, but you must meet specific health and safety criteria.
Birmingham, AlabamaAges 18 years+ - NCT07554287Recruiting

Study of alpelisib for insulin resistance
This study tests a single dose of a drug called alpelisib (a PI3K inhibitor) to see how it affects insulin and blood sugar in people who are either insulin sensitive or insulin resistant. The goal is to understand why some people become resistant to insulin, which may help find new treatments for diabetes and related conditions.

Common questions
- Are there clinical trials for glucose tolerance?
- Yes. Clin2 currently lists 45 recruiting glucose tolerance 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 glucose tolerance 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 glucose tolerance 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.
