You may be eligible if
1. Ambulatory boys age 6 to \<16 years old (at the time of randomization), diagnosed with DMD. Diagnosis must be confirmed in subject's medical history and by genetic testing obtained during routine clinical care for diagnostic purposes as reported from an appropriate regulated laboratory using a clinically validated genetic test (genetic testing is not provided by the sponsor).
2. Subjects who are able to perform the 4 stair climb in \> or = 0.33 but \< or =1.6 stairs/second.
3. Subjects must be receiving glucocorticosteroids for a minimum of 6 months prior to signing informed consent. There should be no significant change (\>0.2 mg/kg) in dosage or dose regimen (not related to body weight change) for at least 3 months immediately prior to signing the informed consent and a reasonable expectation that dosage and dosing regimen will not change significantly for the duration of the study.
4. Adequate hepatic and renal function on screening laboratory assessments.
5. No underlying disposition for iron accumulation on screening laboratory assessments.
6. Iron content estimate on the screening liver MRI is within the normal range.
You may not be if
1. Subjects with known cognitive impairment or behavioral issues that would impede the ability to follow instructions.
2. History of major surgical procedure within 6 weeks of signing the informed consent or planned surgery during the study.
3. Any injury which may impact functional testing. Previous injuries must be fully healed prior to consenting. Prior lower limb fractures must be fully healed and at least 3 months from injury date.
4. Presence or history of other musculoskeletal or neurologic disease or somatic disorder not related to DMD including pulmonary and cardiac disease.
5. Compromised cardiac function (left ventricular ejection fraction \<55% as determined on a screening cardiac MRI or echocardiogram). Subjects may be receiving ACE (angiotensin converting enzyme) inhibitors or beta blockers, ARB (angiotensin II receptor antagonist) or aldosterone blocker/thiazide diuretic; however they must have initiated treatment more than 3 months prior to screening to ensure stable therapy.
6. Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular (including uncontrolled hypertension), hepatic, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing).
7. Documented history of iron overload including hemochromatosis, beta thalassemia major, beta thalassemia intermedia or hemolytic anemia.
8. Unwilling or unable (eg, metal implants, requires sedation) to undergo examination with closed MRI without sedation.
9. Participation in other studies involving investigational drug(s) for a minimum of 30 days or within 5 half lives (whichever is longer) prior to signing the informed consent and/or during study participation.
10. Current or prior treatment with anti-myostatin, exon skipping, nonsense mutation targeted therapies ever or more than 30 days of treatment with utrophin modifiers and treatment with utrophin modifiers within 30 days prior ot signing the informed consent and/or during study participation.
11. Current or prior treatment within the past 3 months with androgens or human growth hormone.
12. Current treatment with immunosuppressant therapies (other than glucocorticoid steroids), aminoglycosides (eg, gentamicin), multi vitamins with iron and iron supplements and other investigational therapies (including idebenone).
