Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 70 with metabolic syndrome and a BMI of 35 kg/m² or higher, who are scheduled for gastric bypass or sleeve surgery.

Probably not a fit

Patients with type 1 diabetes or poorly controlled type 2 diabetes may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the impact of the SGLT2 inhibitor empagliflozin on reducing inflammation in adipose tissue and improving endothelial function in obese patients with metabolic syndrome. The study aims to understand how this medication can potentially mitigate the chronic inflammation associated with obesity, which is linked to increased cardiovascular disease risk. Participants will be randomly assigned to receive either empagliflozin or a placebo, and various health metrics will be monitored throughout the trial.

Why it matters

Potential benefit: If successful, this study could lead to new therapeutic options for managing obesity-related inflammation and improving cardiovascular health.

How similar studies have gone: Other studies have shown promising results with SGLT2 inhibitors in managing metabolic conditions, suggesting potential success for this approach.
