Heart Disease Risk Factors in Black Adults
This study examines why Black men and women have different heart disease risk factors, focusing on weight, cholesterol levels, and diabetes risk. Researchers want to understand these differences to help prevent heart disease in Black communities.
Bethesda, MarylandAges 18–70 - NCT02037867Recruiting
Study your liver blood markers if you’re at risk

Nottingham, NottsAges 18 years+ - NCT01399385Recruiting
MRI and heart scans to test possible heart disease
This study tests new or improved heart imaging methods to understand whether people have heart-related blood vessel disease. It may help by comparing scan results to your health history and other testing to better spot heart problems earlier.
Bethesda, MarylandAges 18–100 - NCT01927783Recruiting
Community weight loss program for people in Washington area

Bethesda, MarylandAges 19–85 - NCT01224886Recruiting
Study of age-related insulin resistance and exercise
This study looks at how age affects the way your body uses insulin (a hormone that helps move sugar into cells), and how lifestyle or exercise may change that. It may help you understand insulin resistance and whether changes in activity could improve blood sugar control.
BernAges 60–80 - NCT01793168Recruiting
Rare disease registry and history study
This study keeps a registry (a structured list) of people with rare diseases and may also track how the condition changes over time. It can help researchers better understand rare illnesses and find gaps in care, which may improve future treatments.
Sioux Falls, South DakotaAges Any age - NCT01945840Recruiting
Study how gut hormones change after weight-loss surgery
This study looks at how gut hormones and blood sugar control change after Roux-en-Y gastric bypass. It may help researchers understand what supports healthier glucose levels after bariatric surgery.
London, Greater LondonAges 18–70 - NCT01477957Recruiting
Bariatric surgery and changes in insulin and body energy use
This study tests whether weight-loss surgery improves how your body uses insulin and energy. It compares insulin sensitivity and related measurements before and after surgery to understand who benefits.
Düsseldorf, North Rhine-WestphaliaAges 20–70 - NCT01869530Recruiting
Nutrition check for preschool kids at participating clinics
This study measures nutrition (what and how much children eat) in young kids during regular primary care visits. It may help improve how doctors check and support children’s nutrition in early childhood.
Toronto, OntarioAges Up to 5 years - NCT01984762Recruiting
Weight-loss surgery for type 2 diabetes
This study tests whether two weight-loss operations (sleeve gastrectomy or Roux-en-Y gastric bypass) can improve type 2 diabetes. It may help people with higher body weight and diabetes control, but it also requires meeting safety and health criteria.
GothenburgAges 18–60 - NCT02166372Recruiting
Testing weight-loss surgery vs standard care for type 2 diabetes
This study compares people with type 2 diabetes and higher body weight who meet criteria for metabolic (weight-loss) surgery versus people with mild obesity who do not. It aims to see whether surgery improves diabetes-related outcomes more than usual medical care.
Taoyuan CityAges 20–67 - NCT02208141Recruiting
Child body growth study with planned surgery
This study follows children’s body growth and fat (adipose) tissue as part of a planned surgical procedure. It aims to improve understanding of how fat tissue develops in childhood and what factors may affect health later.
Leipzig, SaxonyAges Any age - NCT02664831Recruiting
Study of inflammation after cardiac arrest in ICU patients
This trial looks at how the body’s inflammation response behaves after someone has a cardiac arrest and was treated in the ICU. It may help doctors understand which patients could benefit from treatments that target harmful inflammation after resuscitation.
Portland, MaineAges 18 years+ - NCT02904291Recruiting
Blood-pressure medicine study around weight-loss surgery
This study checks how amlodipine (a blood-pressure medicine) gets absorbed in your body before and after gastric bypass or sleeve gastrectomy. It may help doctors better manage blood pressure medicines after weight-loss surgery.
TrondheimAges 18–70 - NCT02811900Recruiting
Study of outcomes after weight-loss (bariatric) surgery
This study follows adults who have bariatric (weight-loss) surgery to see what outcomes they experience afterward. It may help doctors better understand how well the surgery works in real life.

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 - 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 - NCT02273297Recruiting
Healthy Start study for pregnant people and newborns in Colorado

Common questions
- Are there clinical trials for obesity?
- Yes. Clin2 currently lists 1,500 recruiting 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 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 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.
