Can a common diabetes drug help transplant patients?
NCT ID NCT00466518
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how sitagliptin (Januvia) affects levels of anti-rejection drugs and blood sugar in 16 people who had a kidney transplant and have type 2 diabetes. Participants took sitagliptin daily for 3 months. The goal was to see if it is safe and works well in this group.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- sitagliptin (Januvia)
- What this could lead to
- If successful, this could show that sitagliptin is a safe and effective option to help control blood sugar in kidney transplant patients with type 2 diabetes.
- What could go wrong
- This is a very small, early-phase study with only 16 participants, so results may not apply to everyone. The main goal was to check drug interactions, not to prove long-term benefits or safety.
