What the study statuses mean

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 Results may not be published yet.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
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers are testing noninvasive methods to monitor the health of newly transplanted kidneys in people who have received a kidney transplant. The study enrolls about 280 participants who are candidates for deceased or living donor kidney transplants. The goal is to see if these noninvasive tests can predict how well the kidney will function and detect problems early, potentially reducing the need for invasive biopsies.

What this could mean

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

Active substance
noninvasive monitoring tests for kidney transplant recipients
What this could lead to
If these methods work, doctors could track kidney transplant health with simple tests instead of invasive biopsies, catching problems earlier and making follow-up care easier for patients.
What could go wrong
The study may find that noninvasive tests are not accurate enough to replace biopsies or predict outcomes reliably. Results from this group may not apply to all transplant recipients, and the monitoring approach could miss important changes.
