Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Subjects must have a documented diagnosis of Duchenne Muscular Dystrophy (DMD) confirmed by complete dystrophin deficiency (by immunofluorescence and/or immunoblot), or identifiable mutation in the DMD gene where reading frame can be predicated as "out of frame," or complete dystrophin gene sequencing consistent with DMD; AND in the opinion of the Investigator, a typical clinical profile consistent with DMD.
  2. Subjects taking approved treatments for DMD (by a Health Authority) that target dystrophin gene mutations (eg, eteplirsen or ataluren) may be enrolled in the study if they have been on a stable dose for 30 days prior to the first dose of study drug, and plan to remain on that dose throughout the study

Exclusion Criteria:

  1. Subject has had previous systemic treatment with corticosteroids. Transient previous use of corticosteroids will be evaluated on a case-by-case basis by the sponsor or designee. Inhaled corticosteroids will be permitted if given at a stable dose for the 3 months prior to the first dose of study drug and the subject will remain on that dose throughout the study. The use of topical or intra-articular corticosteroids is permitted during the study.
  2. Subject has symptomatic cardiomyopathy in the opinion of the investigator.
  3. Subject is unable to complete the 10 meter Walk/Run test at the Screening and/or Baseline Visit.
  4. Subject has Type 1 or Type 2 diabetes mellitus.
  5. Subject has a history of chronic active hepatitis including acute or chronic hepatitis B, or acute or chronic hepatitis C.
  6. Subject has a history of tuberculosis (TB) infection, any signs/symptoms of TB, or any close contact with an individual with an active TB infection.
  7. Subject has known immune compromised status (not related to disease/condition under study), including but not limited to, individuals who have undergone organ transplantation or who are known to be positive for the human immunodeficiency virus.
