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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is investigating why some people with membranous nephropathy, a kidney disease, respond well to a treatment that depletes certain immune cells (B-cells) while others do not. Researchers will analyze blood samples from 86 patients and healthy volunteers to compare immune cell types and activity. The goal is to find biological markers that predict treatment success and better understand the disease.

What this could mean

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

What this could lead to
If successful, this research could help doctors predict which patients will benefit from B-cell depleting therapy, leading to more personalized treatment for membranous nephropathy.
What could go wrong
This is an observational study, not a treatment trial. It aims to gather knowledge, not test a new therapy. Results may not directly change patient care.
