What this trial studies

This study investigates how dapagliflozin, a Sodium-Glucose Cotransporter-2 (SGLT2) inhibitor, affects vascular health in patients with Type 2 Diabetes Mellitus (T2DM). It employs a two-treatment, two-period crossover design where participants receive either dapagliflozin or a placebo for six weeks, followed by a washout period and then crossover to the alternate treatment. The study aims to assess changes in endothelial cell health, gene expression, and biomarkers to understand the cardiovascular benefits of SGLT2 inhibitors. The total duration for each participant is 14 weeks, including treatment and washout periods.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with Type 2 Diabetes Mellitus for at least three months, with a BMI greater than 25 and specific glucose levels.

Not a fit: Patients currently on anticoagulation therapy, those with a history of certain infections, or those with uncontrolled diabetes may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into how dapagliflozin improves vascular health and reduces cardiovascular risks in patients with Type 2 Diabetes.

How similar studies have performed: Other studies have shown promising results with SGLT2 inhibitors in improving cardiovascular outcomes, making this approach both relevant and potentially impactful.
