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
EXPERIMENTALLow dose cohort - 2.0E10 vg/kg
High Dose
EXPERIMENTALHigh Dose - 1.0E11 vg/kg
Interventions
Recombinant adeno-associated virus (AAV) carrying a truncated human dystrophin gene (mini-dystrophin) expressed from a cytomegalovirus (CMV) promoter.
Eligibility Criteria
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
