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 Results may not be published yet.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

Summary

This study looked at whether raising hemoglobin levels with a drug called epoetin (Neorecormon) could improve quality of life and slow kidney function decline in people who had a kidney transplant and now have chronic graft dysfunction. About 128 adults who had a transplant 1 to 20 years ago and had reduced kidney function took part. They were split into two groups: one aimed for a higher hemoglobin target, the other for a lower one. The study measured quality of life after 6 months and kidney function over 24 months.

What this could mean

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

Active substance
Epoetin (Neorecormon)
What this could lead to
If successful, this could show that managing anemia with epoetin improves daily well-being and helps preserve kidney function in transplant patients.
What could go wrong
This is a completed Phase 4 trial with 128 participants, so results are limited in scope. The intervention may not significantly slow kidney decline or improve quality of life for all patients.
