What this trial studies

This clinical trial investigates the effects of dapagliflozin, an SGLT2 inhibitor, on renal function in heart transplant recipients who are at risk of kidney failure. The study aims to determine whether dapagliflozin can prevent the deterioration of kidney function, while also assessing its impact on weight, glucose levels, proteinuria, and the incidence of transplant rejection. Participants will be monitored for safety and tolerability, as well as various clinical outcomes related to heart and kidney health. This is a Phase 3 interventional trial, indicating a focus on evaluating the efficacy and safety of the treatment in a larger patient population.

Who should consider this trial

Good fit: Ideal candidates are heart transplant recipients who are at least one year post-transplant and are 18 years or older.

Not a fit: Patients with severe kidney impairment, type I diabetes, or other significant health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve kidney health and overall outcomes for heart transplant recipients.

How similar studies have performed: While SGLT2 inhibitors have shown promise in other populations, this specific application in heart transplant recipients is novel and has not been extensively tested.
