A Prospective Natural History Study of Progression of Physical Impairment, Activity Limitation and Quality of Life in Duchenne Muscular Dystrophy.
A Prospective Natural History Study of Progression of Physical Impairment, Activity Limitation and Quality of Life in Duchenne Muscular Dystrophy.
To characterize the natural history and progression of Duchenne Muscular Dystrophy (DMD) to help inform the design of future studies, to capture biomarkers of safety and disease progression and to provide comparative data for the development of rare exons for which formal controlled trials are not feasible.
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 :
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.
