Can a diabetes drug shield transplanted kidneys?
NCT ID NCT06560801
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tests whether dapagliflozin, a drug used for diabetes and kidney protection, can improve kidney structure and blood flow in people who received a kidney transplant one year ago. About 48 participants will be randomly assigned to take dapagliflozin or standard care alone. Researchers will examine kidney biopsies and MRI scans to look for changes in inflammation, scarring, and perfusion.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Dapagliflozin (a diabetes drug that helps protect the kidneys)
- What this could lead to
- If it works, this could show that dapagliflozin helps preserve kidney health in transplant patients, potentially leading to better long-term outcomes.
- What could go wrong
- This is a small, early-phase study (48 people) looking at tissue changes, not hard outcomes like kidney failure. The drug may not show clear benefits or could cause side effects.
