Once-Daily pill may sharpen thinking in older kidney transplant patients

NCT ID NCT06751992

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study compares two anti-rejection drugs in older kidney transplant recipients: a once-daily extended-release version (Envarsus XR) versus the standard twice-daily immediate-release version (Prograf). Researchers will measure changes in thinking, memory, and other cognitive skills over time using standard tests. The goal is to see if the once-daily drug helps preserve or improve brain function better than the twice-daily drug.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
extended-release tacrolimus (Envarsus XR)
What this could lead to
If it works, this could show that a once-daily anti-rejection drug helps older kidney transplant patients maintain or improve their thinking and memory compared to the standard twice-daily drug.
What could go wrong
This is a small, early-phase study (92 people) looking at cognitive test scores, not major health outcomes. The results may not apply to all kidney transplant patients, and the drug switch might not show a clear benefit.
