Dipyridamole to prevent low phosphate after kidney transplant

Official title: Evaluation of Dipyridamole in Preventing Post-Transplant Hypophosphatemia in Kidney Transplant Recipients

Run by Stanford University · NCT06824454 · Data updated 2026-11-12

This study tests whether giving dipyridamole can help keep phosphate levels higher after a kidney transplant and reduce the need for phosphate supplements.

Is this trial a fit for you?

Likely a good fit

Adult kidney transplant recipients without contraindications to dipyridamole.

Probably not a fit

Patients with delayed graft function or those needing Plavix, DOACs, or Coumadin may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this Phase 2 interventional trial, adults who have received a kidney transplant will take dipyridamole 75 mg to see if it improves serum phosphate and lowers dependence on phosphate supplementation. The study targets reducing hypophosphatemia that can occur after transplantation. Participants are selected to exclude those with delayed graft function or who require certain anticoagulants. Stanford University leads the study with no listed collaborators. The trial location is Stanford, California.

Why it matters

Potential benefit: If successful, participants may achieve better phosphate control and fewer phosphate supplements after transplant.

How similar studies have gone: Prior research has explored dipyridamole for phosphate management, but this specific post-transplant approach is relatively novel.
