Obesity Clinical Trials

The purpose of this study is to compare cardiometabolic health between metabolically-normal and metabolically abnormal obese participants. This study will last up to 1 year. Participants will visit the research center about 8 times before randomization.  The outpatient visits range from less than 1 hour to approximately 6 hours in …

Over 30% of adolescents are overweight and 20% are obese, but the mechanisms that produce excessive weight gain in youth remain incompletely elucidated. Some overweight youth appear to have an attention bias (AB: a tendency to attend selectively to stimuli that have acquired salience or meaning) toward highly palatable food …

Some people appear to be more resistant than others to gaining weight when they overeat, though they do not increase their physical activity. This may indicate that adaptive mechanisms exist, which lead to wasting as heat part of the excess calories taken in. Such mechanisms exist in rodents including activation …

This multi-centre real-world study will recruit patients across different National Health Service (NHS) sites based in England, where the overall patient population demographic profile is sufficiently variable to allow for meaningful representation of different ethnicities in the analysis of pooled data-sets. The study addresses the issue of health inequality and …

Being overweight or obese can cause insulin resistance (IR), which is defined as reduced responsiveness to insulin by the cells of various tissues or organs. IR at midlife increases the risk of developing Alzheimer s disease (AD). We recently discovered novel biomarkers of brain IR (altered Tyr and Ser phosphorylated …

A random sample of 45.000 participants between 45 and 74 years of age from the general population of Hamburg, Germany, will take part in an extensive baseline assessment at a dedicated study center. Participants undergo 13 validated and 5 novel examinations primarily targeting cardiac, arterio-venous and cerebral function and structure …

Insulin resistance and a defect in early insulin secretion are risk factors for the development of type 2 diabetes mellitus. A recent longitudinal analysis which tracked the development of diabetes demonstrated that both insulin action and early insulin secretion deteriorate as individuals progress from normal to impaired glucose tolerance and …

Evidence from neuroimaging studies indicates that aberrant functionality in brain regions that support reward processing and habit formation may be related to an individual's eating behavior and obesity propensity. In particular, our previous research found that increased dopamine D2 receptor binding potential (D2BP) in the dorsal and lateral striatum was …

This is a study of tirzepatide in participants with overweight and obesity. The main purpose is to learn more about how tirzepatide affects body weight. The study has two phases: A main phase and an extension phase. The main phase of the study will last 72 weeks (14 visits). Participants …

The researchers are doing the study to see if semaglutide may reduce the risk of having cardiovascular events in patients with overweight or obesity and with prior cardiovascular disease. The participant will either get semaglutide (active medicine) or placebo ("dummy" medicine). Which treatment the participants get is decided by chance. …
