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

LondonAges 18 years+ - NCT05275608Recruiting
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
Mobile app coaching for people with diabetes
This study tests whether using a smartphone app can help people with type 2 diabetes manage their health. It focuses especially on low-income Hispanic/Latinx adults who regularly check blood sugar.
San Diego, CaliforniaAges 18–64 - NCT05289310Recruiting
Home low-oxygen nights to study weight and health
This study looks at whether spending 8 hours each night in a low-oxygen tent for 8 weeks affects weight and related health in people with obesity. It also checks safety by monitoring oxygen levels and screening for breathing and heart-related conditions.
Baton Rouge, LouisianaAges 22–65 - NCT05305313RecruitingPhase 4
Testing a new propofol dosing method for higher BMI surgeries
This trial studies whether adjusting how propofol (an anesthesia medicine) is dosed based on total body weight improves anesthesia delivery during longer surgeries. It mainly targets people with a higher body mass index having surgery that lasts over an hour.
New Delhi, National Capital Territory of DelhiAges 18–65 - NCT05315752Recruiting
Body fat changes after CPAP-treated sleep apnea improves
This study looks at how bariatric (weight-loss) surgery may change body fat and body shape in people with severe obstructive sleep apnea who use CPAP. It aims to understand what may improve when sleep apnea is better controlled after surgery.
BrusselsAges 18–99 - NCT05316935RecruitingPhase 2/Phase 3
Hormone therapy for certain early uterine lining cancers without obesity
This trial tests whether adding GnRH medicine and letrozole to standard progestin treatment can better control early, low-risk endometrial cancer or atypical hyperplasia in people who are not obese. It may help some patients avoid progression while keeping the uterus, especially for those wanting future fertility.
Shanghai, Shanghai MunicipalityAges 18–45 - NCT05320796RecruitingPhase 4
Esomeprazole study after gastric bypass and pouch acid levels
This trial tests how well esomeprazole (a acid-reducing medicine) works after a Roux-en-Y gastric bypass, and how it changes the acidity in the stomach pouch. It may help confirm the best way to control stomach acid after bypass surgery.

Repair of a stomach valve during sleeve weight-loss surgery
This trial tests whether doing a specific repair near the stomach valve (the gastroesophageal junction) during laparoscopic sleeve gastrectomy can help people with a loose valve. It is aimed at adults who have a particular endoscopy finding (Hill grade III) and choose this weight-loss surgery.
SingaporeAges 21–65 - NCT05340868Recruiting

- How do I know if I qualify for a overweight or 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 overweight or 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.
