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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 will test a new wearable device that measures kidney function in real time, compared to the standard 8-hour urine collection method. Researchers will give 200 critically ill patients two dyes (relmapirazin and iohexol) and use a skin sensor to track how quickly their kidneys clear them. The goal is to see if this faster, less cumbersome method is accurate enough for routine hospital use.

What this could mean

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

Active substance
Relmapirazin (Lumitrace) and iohexol
What this could lead to
If successful, this could provide a faster, more accurate way to measure kidney function in hospitalized patients, helping doctors dose medications more precisely.
What could go wrong
This is an early comparison study, not a treatment trial. The device may not prove more accurate than existing methods, and results may not apply to all patients.
