This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.
