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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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

Researchers are following people with Leber congenital amaurosis caused by RPE65 gene mutations to see how their vision and retinas change over time. The study enrolls children and adults, ages 3 and older, who have this inherited retinal dystrophy. Participants undergo regular eye exams, imaging, and questionnaires, but receive no experimental treatment. The goal is to build a detailed picture of the disease's natural course, which could help future trials measure whether new therapies work.

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
Detailed maps of how RPE65-related blindness progresses could help researchers design and measure future gene therapies more effectively.
What could go wrong
This study only observes participants and gives no treatment, so it cannot restore vision. Its small size and focus on one rare genetic form of blindness may limit how far the results apply.
