What this trial studies

This study investigates the impact of mirabegron, a ß3 agonist, on glucose metabolism in obese, insulin-resistant individuals with prediabetes. Participants will receive either mirabegron, tadalafil, a combination of both, or a placebo over a 14-week period. The goal is to determine if these treatments can improve glucose homeostasis and potentially reverse prediabetes. The study will comprehensively analyze changes in glucose tolerance among the different treatment groups.

Who should consider this trial

Good fit: Ideal candidates are obese individuals with a hemoglobin A1C between 5.7 and 6.4 who are prediabetic.

Not a fit: Patients with diabetes or those on chronic antidiabetic medications will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new therapeutic approach to reversing prediabetes and improving metabolic health in obese individuals.

How similar studies have performed: While the combination of mirabegron and tadalafil is a novel approach, previous studies have shown promise in using mirabegron for metabolic improvements.
