Study Details

Brief Summary
Randomized controlled trial (60 month) will compare 3 corticosteroid regimens to address the hypothesis that daily corticosteroids (prednisone vs. deflazacort) will be of greater benefit in terms of function and subject/parent satisfaction than intermittent corticosteroids (prednisone) in patients diagnosed with DMD.


Prednisone, deflazacort or placebo for 60 months.

  • Ability to maintain reproducible FVC measurements.

Exclusion Criteria:

  • Diabetes mellitus.
  • Idiopathic hypercalcuria.
  • Lack of chicken pox immunity and refusal to undergo immunization.
  • Evidence of symptomatic cardiomyopathy at screening assessment (one to three months prior to the baseline visit). Asymptomatic cardiac abnormality on investigation would not be an exclusion.

  • Inability to take tablets, as assessed by the site investigator by the end of the screening period (the screening period ranges from one to three months prior to the baseline visit).
  • Allergy/sensitivity to study drugs or their formulations including lactose and/or sucrose intolerance.
  • Severe behavioral problems, including severe autism.
  • Previous or ongoing medical condition, medical history, physical findings or laboratory abnormalities that could affect safety, make it unlikely that treatment and follow up will be correctly completed or impair the assessment of study results, in the judgment of the site investigator.
