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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 follows 700 people with Alport syndrome, a rare inherited disease that can lead to kidney failure, hearing loss, and eye problems. Researchers will collect health data and samples over time to map how the disease progresses and to find early markers of kidney decline. The goal is to better understand the disease and prepare for future treatment trials.

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 study could reveal early warning signs of kidney failure in Alport syndrome, helping doctors start treatments sooner and guiding the design of future drug trials.
What could go wrong
This is an observational study, not a treatment trial. It will not directly improve health, and results may take years to produce clear findings.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The countries that are potentially interested in joining the project have identified in their local records about 100 (Germany), 200 (Spain), 100 (United Kingdom), 785 (Italy), 100 (Belgium) patients. The database ASTOR in USA have included 800 patients. For France, the CEMARA database contains currently 680 Alport Syndrome patients while there are 950 identified patients in France. These patients are followed in nephrology and paediatric nephrology services belonging to the French network for rare renal diseases. Prevalent cases will include cases already registered in the different existing databases in the different countries, after monitoring that the inclusion criteria are respected. There is no known estimated incident rate, but according to the available information and the estimated prevalence rate (1/5,000), it is expected to enrol roughly between 100 and 200 incident patients/year in the study.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)
