Could a common diabetes drug protect transplanted kidneys?
NCT ID NCT04965935
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether dapagliflozin, a drug used for type 2 diabetes, can lower blood pressure in people who have received a kidney transplant. Fifty-two participants took either the drug or a placebo for 12 weeks. The goal was to see if the drug helps control blood pressure and blood sugar, which are important for keeping the transplanted kidney healthy.
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 lower blood sugar and blood pressure)
- What this could lead to
- If successful, this could point toward a new way to manage blood pressure and diabetes in kidney transplant recipients, potentially improving long-term outcomes.
- What could go wrong
- This is a small, early-phase trial with only 52 participants, so results may not apply to everyone. The drug also carries risks like dehydration or infections in this vulnerable population.

Participation in another trial with an investigational drug within 30 days of informed consent; 11. Alcohol or drug abuse within 3 months prior to informed consent that would interfere with trial participation; 12.
