NCT ID NCT04126005

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.

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 Results may not be published yet.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.

Summary

This study followed 67 children with Canavan disease, a rare genetic brain disorder, to learn how the condition naturally changes over time. Researchers reviewed medical records and conducted checkups to track symptoms, milestones, and disease progression. The goal was to better understand the disease, which may help design future treatments and clinical 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 this study succeeds, it will give doctors and researchers a clearer picture of how Canavan disease progresses, which could help design future treatments and clinical trials.
What could go wrong
This is an observational study, not a treatment trial, so it does not test any therapy. The results may not apply to all patients, and the small number of participants (67) limits how much we can learn.
