NCT ID NCT07151742

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 This study
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 Results may not be published yet.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

Summary

This study tests whether a 12-week exercise program done during dialysis can improve muscle oxygen levels and dialysis quality in kidney patients who also have muscle loss (sarcopenia). About 40 patients will either exercise on a bike and do resistance moves during their first two hours of dialysis, or continue usual care. Researchers will measure muscle oxygen, dialysis effectiveness, strength, and quality of life before and after the program.

What this could mean

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

Active substance
intradialytic combined exercise program (aerobic cycling and resistance training)
What this could lead to
If it works, this could offer a simple, drug-free way to improve muscle health and dialysis effectiveness for kidney patients.
What could go wrong
This is a small, early-stage trial with only 40 participants. The exercise program may be too demanding for some patients, and results may not apply to all kidney patients.

Participants

About 40 people

The number the study aims to enrol. It can still change while the study runs.

Started
