Old heart drug may help kidney transplant patients with low phosphate
NCT ID NCT06824454
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether dipyridamole, a drug usually used for heart conditions, can raise low phosphate levels in kidney transplant recipients. Researchers will give the drug to 90 adult patients when their phosphate drops below normal. The goal is to see if it improves phosphate levels and cuts the need for phosphate supplements.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dipyridamole
- What this could lead to
- If it works, this could offer a new way to manage low phosphate after kidney transplant, reducing the need for supplements.
- What could go wrong
- This is a small, early-phase trial (90 people) testing an off-label drug. It may not show clear benefit, and results may not apply to all transplant patients.
