Subjects must meet all of the following criteria for inclusion in the study at the Screening Visit and at the Baseline Visit (except as noted):
1. Each subject’s parent or legal guardian must be adequately informed and understand the nature and risks of the study and must be able to provide a signature and date on the ICF. In addition, each subject who is capable of understanding it must sign an assent form. The consent and assent (where applicable) for this study must be signed before any protocol required procedures are performed.
2. Subjects must be male and between 4 and 8 years of age (inclusive) at the Screening Visit.
3. Subjects must have a documented diagnosis of 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.
4. 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
5. Subjects should have serum potassium within the reference range at screening. Subjects who have potassium levels below the lower limit of normal may be given potassium supplements and then re-tested within the 28 day screening period.
6. Subjects must test positive for exposure to varicella zoster virus on antibody testing. If subjects test negative, they may be vaccinated and re-tested.
7. Subjects and/or subjects' parent or legal guardian must be able to communicate effectively with study personnel.
8. Subjects and subjects' parent or legal guardian must be able and willing to follow all protocol requirements and study restrictions.
9. Subjects and subjects' parent or legal guardian must be able and willing to return for all study visits.
Are the trial subjects under 18? yes
Number of subjects for this age range:
F.1.2 Adults (18-64 years) no
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) no
F.1.3.1 Number of subjects for this age range
Subjects are ineligible for study participation if they meet any of the following criteria at the Screening Visit and at the Baseline Visit (except as note):
1. Subject is from a vulnerable population (excluding pediatric populations), as defined by the US CFR Title 45, Part 46, Section 46.111(b) and other local and national regulations, including but not limited to, employees (temporary, part-time, full-time, etc) or family members of the research staff conducting the study, or of the sponsor, or of the clinical research organization, or of the IRB/IEC.
2. 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.
3. Subject has been treated with immunosuppressants, or mineralocorticoids (including, but not limited to, spironolactone, eplerone, and carrenone) in the 3 months prior to the Screening Visit.
4. Subject has taken any investigation medication within 30 days or 5 half lifes (whichever is longer) prior to the first dose of study drug.
5. Subject is unwilling to receive, or is intolerant of, SC injections.
6. Subject has symptomatic cardiomyopathy in the opinion of the investigator.
7. Subject is unable to complete the 10 meter Walk/Run test in 10 seconds or less at the Screening and Baseline Visits.
8. Subject has a history of any drug allergy, hypersensitivity, or intolerance to cosyntropin, H.P. Acthar® Gel or other ACTH products.
