Outcome Measures

Primary Outcomes (1)

  • Number of Participants with Adverse Events as a Measure of Safety and Tolerability

    Physical Exams assessing major organ systems and safety labs (GGT, Bilirubin, Glucose, Amylase, CBC/Diff, AFP, Platelets, PT/PTT, Creatinine, Electrolytes, Total protein, Alkaline phosphatase, and Urinalysis)

    followed for 2 years post injection

Secondary Outcomes (2)

  • mini-dystrophin gene expression at the site of gene transfer

    90 days post injection

  • Maximal Volume Isometric Contraction Testing as a measure of muscle strength

    out to 2 years post injection

Study Arms (2)

Low Dose

EXPERIMENTAL

Low dose cohort - 2.0E10 vg/kg

Biological: rAAV2.5-CMV-minidystrophin (d3990)

High Dose

EXPERIMENTAL

High Dose - 1.0E11 vg/kg

Biological: rAAV2.5-CMV-minidystrophin (d3990)

Interventions

Recombinant adeno-associated virus (AAV) carrying a truncated human dystrophin gene (mini-dystrophin) expressed from a cytomegalovirus (CMV) promoter.

Eligibility Criteria

Age5 Years - 15 Years
Sexmale
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Known null mutation of the Dystrophin gene
  • Male age of 5 years or older
  • If taking corticosteroids, must have dose unchanged for the past 3 months
  • Serum creatine kinase elevation greater than 10x normal value (established by Children's Hospital)
  • Progressive, symmetrical proximal muscle weakness of arms and legs

You may not qualify if:

  • Unable to cooperate for muscle strength testing
  • Joint contractures that prohibit muscle strength testing
  • Concomitant illness
  • Individuals predisposed to excessive vagal responses (bradyarrhythmia or hypotension)
  • Controlled substance abuse
