Study of fat tissue in obesity and type 2 diabetes
This study looks at a specific receptor (CB1) in abdominal fat tissue to understand how it affects fat-related chemicals in the body. Your participation would involve giving consent and having a tissue sample taken during planned internal (visceral) surgery.
DijonAges 18–80 - NCT04945473Recruiting
Testing weight-loss surgery follow-up and gastric “recalibration”
This trial studies what happens after a weight-loss procedure called endoscopic sleeve gastroplasty (ESG) and whether a “recalibration” approach can improve results. You may be considered if you have long-term obesity that did not improve with lifestyle/medical treatment.
StrasbourgAges 18–75 - NCT04971720RecruitingPhase 2/Phase 3
Personalized blood pressure timing therapy for some adults
This trial tests whether timing blood pressure medications (based on your natural daily body rhythms) can improve blood pressure control. It’s designed for adults with moderately high blood pressure and focuses on who may benefit from a more precise schedule.
Birmingham, AlabamaAges 18 years+ - NCT04994665Recruiting
Test of fixing the stomach to reduce reflux after sleeve surgery
This study checks whether a surgical “fix” (omentumpexy) can reduce acid reflux after sleeve gastrectomy. It’s mainly for adults having sleeve surgery who have a higher-risk body weight and related health problems.
BayonneAges 18 years+ - NCT04997473Recruiting
Mobile app weight-loss program for young transplant patients
This trial tests whether a phone app can help young people who previously had a stem cell transplant lose weight. It’s designed for people who are at least 100 days out from transplant and who meet weight criteria.
Los Angeles, CaliforniaAges 13–30 - NCT05000996Recruiting
Gut microbiome study for people having metabolic surgery
This study looks at your gut bacteria (your “microbiome”) around the time of metabolic surgery. It may help researchers understand how surgery affects gut health and related conditions like diabetes, blood pressure, and cholesterol.
Nashville, TennesseeAges 21–65 - NCT05008276Recruiting
Study of puberty, diabetes, and kidney stress in teens
This trial studies how puberty and blood sugar changes affect the kidneys in people with type 1 diabetes. It may help researchers understand early kidney risk and identify who needs closer monitoring.
Aurora, ColoradoAges 8–14 - NCT05067231Recruiting
UAB heart research biobank for adults 18 and older
This study builds a heart-focused research database by enrolling adults who are willing to provide information and/or samples for future cardiovascular research. It may help researchers study heart disease and develop better treatments over time.
Birmingham, AlabamaAges 18 years+ - NCT05074732Recruiting
Study of forensic mental health admissions after a service move
This study looks at all adult admissions to Ireland’s National Forensic Mental Health Service during a specific time window. It may help improve how the new forensic service at Portrane runs in the future.
DublinAges 18 years+ - NCT05117424Recruiting
Study of metabolism and plaque changes in heart disease
This trial looks at how treating or managing conditions like diabetes, prediabetes, obesity, kidney disease, or high cholesterol affects artery plaque over time. It may help researchers find ways to slow plaque buildup and related heart risks.
ShanghaiAges 18–80 - NCT05119868Recruiting
Mediterranean diet in pregnancy to prevent baby allergies
This trial studies whether following a Mediterranean-style eating pattern during pregnancy can lower the chance that a child develops allergies. It may help families who already have a higher allergy risk, by changing diet during early pregnancy.
NaplesAges 20–35 - NCT05147909Recruiting
Testing too much phosphate on exercise and belly fat
This trial studies whether eating extra phosphate changes how well you can exercise and how much visceral (deep belly) fat you have. Because it is a crossover study, you would likely try different phosphate amounts on separate occasions.
Dallas, TexasAges 18–80 - NCT05173714RecruitingPhase 2
Sit Less and Move More program for people with CKD
This Phase 2 study tests a program to help people with chronic kidney disease (CKD) sit less and move more, plus a medication (semaglutide) for those who qualify. It may help improve health and day-to-day activity while monitoring safety closely.
Stanford, CaliforniaAges 20 years+ - NCT05197738Recruiting
Study using a sleep health app to improve sleep
This study tests a “sleep health” app (REFRESH) to see how it may help people track and improve sleep. You may be eligible if you’re an adult in the U.S. who can use the app on your own phone.
La Jolla, CaliforniaAges 18 years+ - NCT05199454Recruiting
Study how “fat-like” particles affect blood vessel function
This study looks at whether tiny fat-based particles (“adiposomes”) can affect how well your blood vessels work, especially in people with diabetes and higher body weight. You may be asked to do moderate exercise and other study procedures after passing safety checks.
Chicago, IllinoisAges 18–50 - NCT05216042Recruiting
Study of genetics and heart/metabolic health in adults
This study looks at how genetic markers (DNA) relate to heart health and “metabolic” health (how your body manages sugar and fat). You may be asked to provide genetic samples and follow study health checks and protocols to help researchers understand who is at higher risk.
Birmingham, AlabamaAges 18 years+ - NCT05228860Recruiting
Nutrition support program for adults with type 2 diabetes

Low-carb diet effects in people with metabolic syndrome
This trial studies whether a very low-calorie, low-carb diet (VLCKD) can improve metabolic health in adults with metabolic syndrome, fatty liver, and type 2 diabetes. It may help lower blood sugar and improve related health markers if you fit their specific diabetes and liver/kidney criteria.
Novara, ItalyAges 25–65 - NCT05279729Recruiting

- Yes. Clin2 currently lists 1,535 recruiting overweight or obesity 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 overweight or obesity 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 overweight or obesity 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.
