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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

People on long-term dialysis can build up protein-bound toxins like indoxyl sulfate and p-cresyl sulfate that standard dialysis clears poorly. This study at one center in Shanghai tests whether adding a pHA130 hemoperfusion cartridge to regular dialysis or hemodiafiltration lowers those toxins more than dialysis alone. About 109 adults who have been on thrice-weekly, four-hour dialysis for at least three months take part. Researchers measure toxin levels at the start and again at weeks 4, 12, and 24, and also track itching, sleep, quality of life, hospital stays, 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
pHA130 hemoperfusion device, a blood-filtering cartridge added to standard dialysis
What this could lead to
If it works, adding this cartridge to regular dialysis could help clear toxins that standard dialysis leaves behind, possibly easing itching and sleep problems for people on dialysis.
What could go wrong
This is a single-center study of about 109 people, so results may not apply everywhere. The cartridge adds cost and complexity, and it may not lower toxin levels enough to change symptoms or outcomes.
