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 Results may not be published yet.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.

Summary

Researchers in China are enrolling people with biopsy-confirmed primary IgA nephropathy into a long-term registry. Participants are followed once a year, with baseline and follow-up details recorded in a database. The study tracks deaths from any cause and heart-related deaths, plus a combined kidney measure of doubled creatinine and end-stage renal failure. The goal is to understand how the disease progresses across a large group of patients.

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
A detailed picture of how IgA nephropathy progresses could help doctors identify who faces the highest risk of kidney failure and guide future treatment decisions.
What could go wrong
This registry only observes patients and does not test any treatment, so it cannot prove what works. Findings from one country's hospitals may not apply to patients elsewhere.
