Recruiting studies
- NCT03407833Enrolling by invitation
Study changes in the body after weight, gut, or liver treatment
This study looks at how the body’s insulin-sensitivity (how well your body uses sugar/insulin) and organ function change after certain medical procedures. It may help researchers understand why some people improve after surgery or liver transplant and guide future care.
Nashville, TennesseeAges 18 years+ - NCT03476551Recruiting
Gastric bypass or sleeve check for a water-pill response
This study looks at how well hydrochlorothiazide (a “water pill”) works in the body after gastric bypass or sleeve surgery. It may help doctors better predict dosing and effects after these weight-loss operations.
TrondheimAges 18–70 - NCT03449485Recruiting
Blood medicine study around weight-loss stomach surgery
This study looks at how a medicine (chlorprothixene) moves through the body before and after weight-loss surgery like gastric bypass or sleeve gastrectomy. It may help doctors understand the best timing and dosing of this medicine for people having these operations.
TrondheimAges 18–70 - NCT03025074Recruiting
Blood sample bank for liver disease research
This study collects blood samples to build a “biobank” (a stored library of samples) for researchers studying liver diseases like hepatitis, fatty liver disease, and liver cancer. It may help future testing and treatments by allowing scientists to study patterns in people with and without liver conditions.
Buffalo, New YorkAges 7 years+ - NCT02829619Recruiting
Eating at Set Times to Help with Weight Loss
This study looks at whether changing when you eat, along with looking at your genes, can help people lose weight. It’s mainly for adults who are above a healthy weight range and don’t have certain health conditions or medicines.
Murcia, MurciaAges 18 years+ - NCT02861781Recruiting
Collecting body tissue samples during bariatric surgery
This study collects small tissue samples during planned weight-loss surgery to better understand metabolism and how insulin works in people with and without type 2 diabetes. You may help researchers by allowing their team to take these samples while you are already having surgery.
MontpellierAges 18–65 - NCT02939664Enrolling by invitation
Laparoscopic gastric bypass vs banding for weight loss
This trial compares two types of minimally invasive weight-loss surgery: gastric bypass versus a gastric band. It looks at which approach works better and is safer for people who qualify for bariatric surgery and have not succeeded with supervised weight-loss programs.
Majadahonda, MadridAges 18–65 - NCT02390765Recruiting
Study of growth, weight, and behavior in children
This study looks at how children’s growth and weight relate to thinking, mood, and behavior. It may help researchers understand what patterns affect health and development so they can guide better support for families.
Bethesda, MarylandAges 8–100 - NCT02646475RecruitingPhase 1
Study angiotensin medicine to improve metabolism in obesity
This Phase 1 study tests how a medication that affects the body’s angiotensin system (angiotensin-(1-7)) changes metabolism in adults with obesity, insulin resistance, and high blood pressure. It may help researchers understand whether this approach can improve blood sugar/insulin function and related body changes.
Nashville, TennesseeAges 18–60 - NCT02669797Enrolling by invitation
Family-based program to help families eat dinner together
This study offers an intervention focused on family dinners to help children improve their eating habits. It targets children who eat family dinners rarely and have a higher weight range, to see if the program can help improve health over time.
Aurora, ColoradoAges 5–10 - NCT01316783Enrolling by invitation
Genetics study of obesity, diabetes, and heart risk
This study looks at genetic differences in adults from African diaspora groups to better understand risks for obesity, type 2 diabetes, and heart disease. You may help scientists learn why these conditions are more common in certain communities.
Bethesda, MarylandAges 18–120 - NCT01399385Recruiting
New heart imaging to detect heart disease
This study tests new imaging techniques, like MRI and CT scans, to better see heart and blood vessel problems. It may help doctors find heart disease earlier and guide treatment.
Bethesda, MarylandAges 18–100 - NCT01927783Recruiting
Community weight loss program for people in Washington area
This study tests a community-based behavioral weight loss program. It may help participants learn practical habits for healthier weight by working with people in local faith communities.
Bethesda, MarylandAges 19–85 - NCT02043457Recruiting
Study factors that predict long-term weight loss success
This study looks for traits (like health measurements or medical factors) that can help predict who will successfully lose weight and keep it off. It may help researchers personalize weight-loss plans in the future.
Ann Arbor, MichiganAges 15–75 - NCT02024542Recruiting
How the body changes after bariatric surgery
This study looks at how metabolism (how your body handles food and energy) responds after weight-loss surgery. It may help researchers understand what changes to expect in people with diabetes or prediabetes and cholesterol problems.
Sacramento, CaliforniaAges 18–55 - NCT01055054Enrolling by invitation
Bariatric surgery registry for people with severe weight gain
This study is a registry, meaning it collects health information to better understand outcomes after bariatric (weight-loss) surgery. It may help doctors improve care for people with severe obesity who had surgery at VCU Medical Center.
Richmond, VirginiaAges 12–75 - NCT00001853Recruiting
Heart disease risk study in Black adults
This study looks at how obesity and blood fat (triglyceride) levels affect heart disease risk differently in Black men and women. You may join if you're a healthy Black adult between 18 and 70, without diabetes.
Bethesda, MarylandAges 18–70 - NCT01143454Recruiting
Study unusual heart conditions and related genetic traits
This study looks at people with unusual or rare heart problems, or people with a family history of these issues. Doctors and researchers may collect and study your blood or tissue (and possibly store samples) to learn what causes the condition and how it may affect the heart.

Common questions
- Are there clinical trials for obese?
- Yes. Clin2 currently lists 1,434 recruiting obese 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 obese 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 obese 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.
