- Observational Model: None

Eligibility Criteria:
Inclusion Criteria:~1. Subject's parent(s) or legal guardian(s) has (have) provided written informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization, where applicable, prior to any study-related procedures; participants will be asked to give written or verbal assent according to local requirements~2. Subject has a centrally confirmed (by TRiNDS central genetic counselor\[s\]) diagnosis of DMD as defined as:~   * Dystrophin immunofluorescence and/or immunoblot showing complete dystrophin deficiency, and clinical picture consistent with typical DMD, OR~  * Identifiable mutation within the DMD gene (deletion/duplication of one or more exons), where reading frame can be predicted as 'out-of-frame,' and clinical picture consistent with typical DMD, OR~  * Complete dystrophin gene sequencing showing an alteration (point mutation, duplication, other) that is expected to preclude production of the dystrophin protein (i.e., nonsense mutation, deletion/duplication leading to a downstream stop codon), with a clinical picture consistent with typical DMD;~3. Subject is ≥ 4 years and \<7 years of age at time of enrollment in the study;~4. Subject weighs \>13.0 kg and ≤ 39.9 kg at the Screening Visit;~5. Subject is able to walk independently without assistive devices;~6. Subject is able to complete the Time to Stand Test (TTSTAND) without assistance in \<10 seconds, as assessed at the Screening Visit;~7. Clinical laboratory test results are within the normal range at the Screening Visit, or if abnormal, are not clinically significant, in the opinion of the Investigator. \[Notes: Serum gamma glutamyl transferase (GGT), creatinine, and total bilirubin all must be ≤ upper limit of the normal range at the Screening Visit. An abnormal vitamin D level that is considered clinically significant will not exclude a subject from randomization\];~8. Subject has evidence of chicken pox immunity as determined by:~   * Presence of IgG antibodies to varicella, as documented by a positive test result from the local laboratory from blood collected during the Screening Period, OR~  * Documentation, provided at the Screening Visit, that the subject has had 2 doses of varicella vaccine, with or without serologic evidence of immunity; the second of the 2 immunizations must have been given at least 14 days prior to randomization.~9. Subject is able to swallow tablets, as confirmed by successful test swallowing of placebo tablets during the Screening Period; and~10. Subject and parent(s)/guardian(s) are willing and able to comply with scheduled visits, study drug administration plan, and study procedures.~Exclusion Criteria:~1. Subject has current or history of major renal or hepatic impairment, diabetes mellitus or immunosuppression;~2. Subject has current or history of chronic systemic fungal or viral infections;~3. Subject has had an acute illness within 4 weeks prior to the first dose of study medication;~4. Subject has used mineralocorticoid receptor agents, such as spironolactone, eplerenone, canrenone (canrenoate potassium), prorenone (prorenoate potassium), mexrenone (mexrenoate potassium) within 4 weeks prior to the first dose of study medication;~5. Subject has a history of primary hyperaldosteronism;~6. Subject has evidence of symptomatic cardiomyopathy \[Note: Asymptomatic cardiac abnormality on investigation would not be exclusionary\];~7. Subject is currently being treated or has received previous treatment with oral glucocorticoids or other immunosuppressive agents \[Notes: Past transient use of oral glucocorticoids or other oral immunosuppressive agents for no longer than 1 month cumulative, with last use at least 3 months prior to first dose of study medication, will be considered for eligibility on a case-by-case basis, unless discontinued for intolerance. Inhaled and/or topical glucocorticoids are permitted if last use is at least 4 weeks prior to first dose of study medication or if administered at stable dose beginning at least 4 weeks prior to first dose of study medication and anticipated to be used at the stable dose regimen for the duration of the study\];~8. Subject has an allergy or hypersensitivity to the study medication or to any of its constituents;~9. Subject has used idebenone within 4 weeks prior to the first dose of study medication;~10. Subject has severe behavioral or cognitive problems that preclude participation in the study, in the opinion of the Investigator;~11. Subject has 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 opinion of the Investigator;~12. Subject is taking (or has taken within 4 weeks prior to the first dose of study medication) herbal remedies and supplements which can impact muscle strength and function (e.g., Co-enzyme Q10, creatine, etc);~13. Subject is taking (or has taken within 3 months prior to the first dose of study medication) any medication indicated for DMD, including Exondys51 and Translarna;~14. Subject has been administered a live attenuated vaccine within 14 days prior to the first dose of study medication;~15. Subject is currently taking any other investigational drug or has taken any other investigational drug within 3 months prior to the first dose of study medication;~16. Subject has a sibling who is currently enrolled in any vamorolone study or Expanded Access Program, or who intends to enroll in any vamorolone study or Expanded Access Program during the subject's participation in the VBP15-004 study; or~17. Subject has previously been enrolled in the study. Note: Any parameter/test may be repeated at the Investigator's discretion during Screening to determine reproducibility. In addition, subjects may be rescreened if ineligible due to a transient condition which would prevent the subject from participating, such as an upper respiratory tract infection or injury, or if ineligible due to negative anti-varicella IgG antibody test result.
