Could a diabetes drug shield heart transplant patients from kidney failure?
NCT ID NCT05321706
First seen Jul 01, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This trial tests whether dapagliflozin (Farxiga), a drug originally developed for diabetes, can protect kidney function in people who have received a heart transplant. Kidney failure is a common and serious complication after heart transplant. The study involves 430 participants who will take either dapagliflozin or a placebo daily for one year, with researchers measuring changes in kidney function and other health outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dapagliflozin (Farxiga)
- What this could lead to
- If it works, this could offer a new way to protect kidney function in heart transplant patients, reducing the risk of kidney failure and improving long-term outcomes.
- What could go wrong
- This is a Phase 3 trial, but SGLT2 inhibitors have not been tested in heart transplant recipients before, so unexpected side effects or lack of benefit are possible. The trial lasts one year, so long-term effects are not yet known.
