Study Aim

This study aims to evaluate the effectiveness of Dapagliflozin in protecting kidney function in heart transplant recipients, by observing changes in estimated Glomerular Filtration Rate (eGFR) from 2 weeks to the end of treatment (12 months).

Actual date on which the first participant was enrolled.

The DAPARHT study focuses on heart transplant recipients, a group that often faces long-term side effects from immunosuppressive therapy. One such side effect is chronic renal failure, which occurs in about 11% of patients within five years post-transplant and significantly increases mortality. The study aims to evaluate the potential benefits of Dapagliflozin, a sodium-glucose cotransporter-2 inhibitor (SGLT2i), in protecting against renal damage. SGLT2i drugs have shown promise in reducing hospitalization for heart failure and slowing kidney disease progression in patients with type 2 diabetes, and this study hopes to extend these benefits to heart transplant recipients.
