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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two approaches to removing excess fluid in intensive care patients with acute kidney injury who are on dialysis. One group will have fluid removed at a moderate rate to actively reduce fluid buildup, while the other group will have fluid removed slowly to just maintain current levels. The goal is to see which strategy leads to fewer days on life support and better recovery. The trial plans to enroll 250 adults in the ICU.

What this could mean

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

Active substance
ultrafiltration (fluid removal) procedure
What this could lead to
If successful, this could establish a safer, more effective way to remove excess fluid in ICU patients on dialysis, potentially reducing time on life support and improving survival.
What could go wrong
This is a moderate-sized early-stage trial, so results may not apply to all ICU patients. Aggressive fluid removal can cause low blood pressure or organ injury, and the benefit over standard care is unproven.
