Safety Study of Eteplirsen to Treat Early Stage Duchenne Muscular Dystrophy
An Open-Label, Multi-Center Study to Evaluate the Safety, Efficacy and Tolerability of Eteplirsen in Early Stage Duchenne Muscular Dystrophy
This is an open-label study to assess the safety, tolerability, efficacy and pharmacokinetics of eteplirsen in patients with early stage Duchenne muscular dystrophy (DMD) who are amenable to exon 51 skipping.

Safety, including adverse event monitoring and routine laboratory assessments, will be followed on an ongoing basis for all patients.

Clinical efficacy, including functional tests and MRI, will be assessed at regularly scheduled study visits. Patients will undergo one baseline and one follow-up muscle biopsy.

Population and serial PK will be collected.
