Obesity Complicating Type 1 Diabetes: GLP-1 Analogue Anti-obesity

Status Not yet recruiting

Clinical Trial Summary

More than 40% of young adults with type 1 diabetes (T1D) also have overweight or obesity. Each of these diagnoses increase the risk of adverse cardiovascular events. GLP-1 analogues are anti-obesity medications that are cardioprotective in adults with type 2 diabetes, however evaluation of these agents in people with T1D has been limited to glycemic outcomes. Investigators aim to study the impact of GLP-1 analogue obesity treatment on markers of cardiometabolic risk in young adults with T1D and obesity.

Clinical Trial Description

This proposal will address critical knowledge gaps of understanding potential salutary effects of GLP-1 analogue anti-obesity treatment with weekly semaglutide 2.4 mg on cardiometabolic risk factors in young adults with T1D and obesity, the group of people with T1D at greatest risk for future cardiovascular disease. Investigators aim to examine the impact of 12 months of treatment with weekly semaglutide 2.4 mg compared to placebo on abdominal adipose tissue distribution, glucose metabolism and postprandial atherosclerotic lipoproteins in young people with T1D and obesity. This is a single-center, parallel group, double-blinded, placebo controlled, randomized clinical trial. After informed consent procedures, participants will complete four assessments: 1) Abdominal MRI to evaluate abdominal adipose partitioning, 2) Euglycemic hyperinsulinemic clamp with isotope tracer enhancement to evaluate gluconeogenesis and glucose, glycerol, and b-hydroxybutyrate turnover to assess measures of insulin resistance, 3) DEXA scan to evaluate total body composition, and 4) a High-fat mixed meal tolerance test to evaluate postprandial lipemia. After completing these baseline measures, participants will be randomized in a 2:1 ratio to receive weekly injected semaglutide (escalated to 2.4 mg or maximum tolerated dose) or placebo to treat obesity for 52 weeks. At 52 weeks, participants will repeat the baseline tests. They will then complete a wean off of study drug (up to 4 weeks) and 2 weeks of additional monitoring for insulin titration. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
