Metformin to reduce weight gain from antipsychotic medicines
This trial tests whether metformin can help adults with intellectual disability who gained weight from long-term antipsychotic medicines. If you qualify, you may be assigned metformin to improve weight and related health measures.
Toronto, OntarioAges 16–65 - NCT05746039RecruitingPhase 1/Phase 2
Testing semaglutide for advanced lung disease
This study checks whether semaglutide is safe and feasible for people with advanced lung diseases and higher body weight. It may help by testing a structured treatment approach, but it includes several health and safety limits.
Philadelphia, PennsylvaniaAges 18–80 - NCT05750732Recruiting
Study weight loss and a gene variant
This trial looks at how weight loss relates to a specific gene difference (CLOCK 3111T/C). You may be eligible if you’re in a certain age and body-mass range and don’t have conditions or medicines that could affect weight or metabolism.
AnkaraAges 20–50 - NCT05774652Recruiting
Teen study following mothers from an earlier pregnancy project
This study follows teenagers whose mothers took part in an earlier lifestyle-in-pregnancy study (started in 2007–2010). It may help researchers understand how that earlier study relates to teen health and development.
OdenseAges 13–65 - NCT05775627Recruiting
Study how sleep affects metabolism in healthy adults
This trial studies how changes in sleep and the body’s daily rhythm may affect metabolism (how your body handles energy and sugar). It is for generally healthy, medication-free young adults who follow a controlled diet and sleep schedule.
Portland, OregonAges 18–40 - NCT05775497Recruiting
Online weight-loss program for sexual minority women
This study tests an online weight-loss program, with added culturally tailored parts, for sexual minority women who want to lose weight. It may help by coaching healthier habits through email and internet tools.

Tests satiety changes after bariatric surgery revision
This study looks at how feelings of fullness (satiety) change in people getting bariatric surgery—either a sleeve gastrectomy or a revision procedure. It may help improve how well weight-loss stays on track after surgery.
MilanAges 18–65 - NCT05783466Recruiting
Testing how dairy affects heart risk in people with high weight
This study looks at whether eating more dairy (from cow’s milk) changes markers linked to heart and metabolic risk in adults with higher body weight. It mainly aims to understand how diet affects the body’s metabolism and related risk factors.
Pierre-BéniteAges 18–70 - NCT05783765Recruiting
Food, genetics, and behavior study for healthy children
This study looks at how eating, body factors (like weight), and behavior may relate to genetics in healthy children. Your child’s participation could help researchers understand why eating habits differ between families.
Philadelphia, PennsylvaniaAges 5–7 - NCT05791305Recruiting
Testing programs to improve childhood nutrition
This study looks at how a nutrition and care program affects children under age 5 who attend it. It aims to help reduce the “double burden” of malnutrition—problems that can happen when children have both undernutrition and excess weight or related nutrition issues.
Addis Ababa, AmharaAges 2–5 - NCT05802121RecruitingEarly Phase 1
Testing a gut bacteria supplement side effects during prostate hormone therapy
This early-phase study looks at how changing gut bacteria (especially Akkermansia) affects metabolic side effects in men starting prostate hormone therapy (ADT). It may help researchers understand how to reduce or manage side effects for people on ADT.
London, OntarioAges 18 years+ - NCT05801614Recruiting
Tested diet to help control glucose in early type 2 diabetes
This study tests whether carbohydrate or calorie restriction can help normalize blood sugar levels in people with relatively early type 2 diabetes. It may help those whose diabetes control is not yet fully under control but who do not have major recent heart problems.
StockholmAges 24–70 - NCT05806801Recruiting
Study how weight loss changes the body with or without exercise
This study looks at how your metabolism (how your body uses energy and controls blood sugar/fats) changes during weight loss, comparing weight loss alone versus weight loss plus exercise. It may help researchers understand what body changes happen with different approaches and why.
Ann Arbor, MichiganAges 18–40 - NCT05816798RecruitingPhase 2/Phase 3
Laser treatment to reduce chronic knee pain before weight-surgery
This trial tests whether photobiomodulation (a type of laser/light therapy) can reduce chronic pain in both knees for people preparing for bariatric (weight-loss) surgery. If you have knee pain that limits daily life, the treatment may help you feel better while you’re in the pre-surgery rehabilitation period.

Semaglutide to help restart periods in PCOS
This Phase 3 study tests whether semaglutide can help people with polycystic ovary syndrome (PCOS) start ovulating and having more regular periods. You may join with or without metformin, and contraception rules are important because the medicine must not be used during pregnancy.
Aurora, ColoradoAges 12–35 - NCT05833217Recruiting
Study for persistent COVID symptoms with insulin resistance

Palo Alto, CaliforniaAges 18–80 - NCT05838950Recruiting
Short high-intensity exercise program for cardiometabolic health
This trial studies whether a structured, short high-intensity exercise program can improve health markers related to weight, blood sugar, and blood fats in young adults with obesity. It may help you see if this kind of exercise leads to measurable health improvements.

Acupressure vs eating plan breaks for specific stomach syndrome
This study compares ear (auricular) acupressure to an intermittent dietary restriction approach in children who have a particular “stomach heat and dampness” pattern from Traditional Chinese Medicine.

- 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.
