Major study aims to better measure muscular dystrophy progression

NCT ID NCT05989620

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 24-month observational study will follow up to 1000 people with certain types of muscular dystrophy (LGMD, DM2, and late-onset Pompe disease) aged 6-50. Researchers want to see if specific physical tests, like the North Star Assessment and a 100-meter walk, are good ways to track the disease over time. The goal is to improve how we measure the condition in future studies, not to test a new treatment.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age between 6-50 years at enrollment 2. Clinically affected (defined as weakness on bedside evaluation in a pattern consistent with proximal weakness) 3. Genetic confirmation of a LGMD, DM2, or LOPD 4. FVC above 30% of predicted Exclusion Criteria: 1. Any other illness that would interfere with the ability to undergo safe testing or would interfere with interpretation of the results in the opinion of the site investigator 2. Participation in a clinical trial receiving an investigational product
