A Prospective Natural History Study of Progression of Subjects With Duchenne Muscular Dystrophy. - Full Text View

Purpose

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.

Primary Outcome Measures:

6 minute walk distance [ Time Frame: Change from visit 1 walking distance ] [ Designated as safety issue: No ]
Participants are asked to walk at their own preferred speed on a fixed distance for 6 minutes. Subjects are warned of the time and that they may stop earlier if they feel unable to continue. Total distance walked within 6 minutes (or until stopping) is recorded.

Biospecimen Retention: Samples Without DNA

Blood sampling at 4 time points (first visit then once a year). Urinalysis sampling at 4 time points (first visit then once a year).

Estimated Enrollment:	250
Study Start Date:	September 2012
Estimated Study Completion Date:	December 2017
Estimated Primary Completion Date:	December 2016 (Final data collection date for primary outcome measure)

Groups/Cohorts	Assigned Interventions
Study participants All participants will follow the same protocol, including muscle strength and function testing, and blood and urine collection, for a maximum of 7 visits over 3 years.	Other: Observational study There is no medication or device tested in this study. This is an obversational study on the progression of the disease.

Detailed Description:

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.

Eligibility

Ages Eligible for Study:	3 Years to 18 Years
Genders Eligible for Study:	Male
Accepts Healthy Volunteers:	No
Sampling Method:	Non-Probability Sample

Study Population

Subjects diagnosed with DMD resulting from a mutation in the DMD gene which is confirmed by a state of the art DNA diagnostic technique covering all DMD gene exons

Criteria

Able to give informed assent and/or consent in writing signed by the subject and/or parent(s)/legal guardian (according to local regulations)

Exclusion Criteria:

Current participation in a clinical study with an Investigational Medicinal Product (IMP)
Participation within the previous 1 month in a clinical study with an IMP
