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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tests whether a structured arm exercise program can help arteriovenous fistulas (AVFs) mature properly in people with chronic kidney disease who need hemodialysis. AVFs are surgically created connections between an artery and a vein that allow for dialysis, but up to half of them fail to develop adequately. Researchers will compare patients who follow a specific exercise routine with those who do not, measuring fistula size, blood flow, and function after eight weeks. If exercise helps, it could offer a simple, drug-free way to improve dialysis outcomes.

What this could mean

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

Active substance
structured physical exercise program
What this could lead to
If effective, this simple exercise program could become a standard, low-cost way to improve fistula success rates, making dialysis safer and more reliable for kidney patients.
What could go wrong
This is a relatively small, single-center trial. Exercise may not significantly improve fistula maturation, and results may not apply to all patients or settings.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 128 people

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

Started
