Role of Caveolin 1 (CAV-1) Deficiency in Response to Glucagon-like Peptide 1 (GLP-1) Receptor Agonist Treatment
NCT06069622 · Recruiting
Last updated 2026-05-28This clinical trial is studying how a protein called Caveolin 1 (CAV-1) might affect the way overweight or obese individuals respond to a medication that mimics a natural hormone called GLP-1.

Description as written by the study sponsor.
Obesity has become an important public health issue that leads to insulin resistance, diabetes, hypertension, dyslipidemia, and cardiovascular diseases. Although weight loss with calorie restriction and increased physical activity improve these complications, many people fail these lifestyle interventions. Therefore, pharmacologic agents have been used for weight management in addition to lifestyle interventions. In the past few years, one of the widely used pharmacologic agents for weight management is Glucagon-like peptide 1 receptor agonists (GLP1 RAs). Overall, this class of medications improves both metabolic and cardiovascular profiles while causing weight loss, but their effects can vary between individuals. Therefore, it is essential to understand who will respond best to this therapy. Based on previous research on the interaction between a cell membrane molecule, caveolin-1, and glucagon-like peptide 1 receptor, we hypothesize that genetic variations in the caveolin-1 gene explain the variable cardiometabolic responses.
Treatments tested
- 24-hour ambulatory blood pressure also known as Blood collection, Urine collection Diagnostic test
24-hour ambulatory blood pressure, blood, and urine will be obtained prior to semaglutide therapy and after 20 weeks of semaglutide therapy.
- Liberal salt diet Dietary supplement
Participants will be on a liberal salt (about 200 mEq sodium/day) diet for 7 days.
