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 Results may not be published yet.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 follows up to 400 children with Pompe disease to see how their immune system reacts to enzyme replacement therapy. Researchers will collect medical records from birth to age 18 to understand which children develop antibodies that block treatment. The goal is to improve care by identifying who might benefit from immune-suppressing drugs alongside standard therapy.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
alglucosidase alfa (Myozyme/Lumizyme)
What this could lead to
If successful, this study could help doctors predict which children with Pompe disease will respond best to enzyme therapy and who might need immune suppression.
What could go wrong
This is an observational study, not a treatment trial. It will not directly test a new therapy, so any benefits are indirect and long-term.
