|Condition or disease||Intervention/treatment|
|Duchenne Muscular Dystrophy||Other: Observational study|
This is a prospective study. All DMD patients that fulfil the inclusion/exclusion criteria are eligible although the study is weighted towards ambulant subjects aged 3 years or older. There will be 7 study visits and subjects will be in the study for a maximum of 3 years. Visits will occur every 6 months (+/- 1 month).
Up to 250 DMD subjects planned in the following categories :
- 75 % ambulant subjects aged between 3 and 18 years at study entry
- 25% non-ambulant subjects with a maximum age of 18 years at study entry
Subjects will be asked to perform muscle testing assessment with a clinical evaluator, such as walking for 6 minutes, climb stairs, breathe in a tube, see how they can move their arms and legs. They will be asked questions about how they feel overall and perform daily activities. These measurements will be assessed every 6 months.
Urine and blood samples will be collected once a year to measure biomarkers that will allow to have a better overview of DMD.
