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 Results may not be published yet.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

This study aims to build a large, multi-center database of people with IgA nephropathy, a kidney disease. Researchers will collect detailed medical information from about 2,000 participants to track how the disease progresses over time. The goal is to create a standardized resource that can support future research and improve understanding of the condition.

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
This could lead to better ways to predict and monitor kidney disease progression in IgA nephropathy, potentially improving care and treatment decisions.
What could go wrong
As an observational database study, it cannot test new treatments. Its value depends on data quality and long-term follow-up, which may be incomplete.

This is an AI summary of the original study and may miss details. Read our disclaimer.
