What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This pilot study tests whether time-restricted eating (eating all meals within an 8-hour window each day) can reduce protein in the urine and slow kidney function decline in people with moderate chronic kidney disease. Fifty adults with stage 2-3 CKD and elevated albuminuria will follow either the 8-hour eating plan or their usual eating pattern for 12 weeks. Researchers will measure changes in kidney markers, blood pressure, body composition, and safety.

What this could mean

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

Active substance
time-restricted eating (behavioral intervention)
What this could lead to
If successful, this could point toward a simple dietary strategy to help manage chronic kidney disease and reduce protein leakage.
What could go wrong
This is a small pilot study with only 50 participants, so results may not apply broadly. Dietary changes can be hard to maintain, and the effect on kidney function may be modest or absent.
