Effects of Mirabegron on Beige Fat Activation in Prediabetic Patients

Mechanisms for Activation of Beige Adipose Tissue in Humans

Phase 2 Interventional University of Kentucky · NCT04666636

This study is testing if the drug mirabegron can help people with prediabetes by activating a type of fat that may improve their blood sugar levels and overall metabolism.

What this trial studies

This clinical trial investigates the impact of the drug mirabegron, a specific ß3 adrenergic receptor agonist, on glucose tolerance and adipose tissue in individuals with prediabetes. The study aims to explore how mirabegron can activate beige adipose tissue, which may help improve insulin sensitivity and glucose homeostasis. Participants will be randomly assigned to receive either mirabegron or a placebo, and their metabolic responses will be monitored throughout the trial. The research is based on the premise that activating beige fat could provide a novel approach to managing prediabetes and obesity.

Who should consider this trial

Good fit: Ideal candidates for this study are adults with a BMI between 27 and 45 who have been diagnosed with prediabetes.

Not a fit: Patients with diabetes or those on chronic anti-diabetic medications are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new treatment options for improving glucose metabolism and preventing the progression of prediabetes.

How similar studies have performed: Previous studies have shown promising results with similar approaches using ß3 adrenergic receptor agonists in obese populations, indicating potential for success in this trial.
