Inclusion Criteria

1) Evidence of signed and dated informed consent form indicating that the subject and his parents or guardian (according to local legislation) have been informed about all pertinent aspects of the study. The child might be asked to give his assent, possibly in writing, if considered intellectually capable, in line with the legal requirements in the participating countries and with the permission of the parent(s)/guardian(s). 2) Confirmed diagnosis of Duchenne muscular dystrophy defined as: Male with proximal weakness AND a confirmed DMD mutation in the dystrophin gene (out of frame deletion OR point mutation OR duplication) OR absent/< 3% dystrophin on muscle biopsy (by immunohistochemistry or Western blot). 3) Age = 4 years and < 8 years. 4) Ability to rise independently from floor, from supine to standing, as assessed at screening visit. 5) Willingness and ability to comply with scheduled visits, drug administration plan and study procedures (including laboratory tests, NSAA, 6MWT, ECG, Echo, wrist X-Ray, DXA, PedsQL and TSQM questionnaires) as assessed by the site investigator at the end of the screening period. 6) Ability to maintain reproducible FVC measurements. Boys must have reproducible measurements of FVC. The boy will be observed to insure complete understanding of the instructions and that he has given maximal effort. If the values continue to increase, the boy may be learning and testing will continue, if necessary, beyond the 3 required trials until the boy reaches a plateau. The evaluator will use his/her expert judgment as to whether or not the boy can produce, and will likely be able to continue to produce, a reliable FVC measurement.
