Brief Summary:
This is an open-label, extension study of NS-065/NCNP-01 administered intravenously once weekly for an additional 192 weeks to boys with DMD who complete Study NS-065/NCNP-01-201.

Condition or disease Intervention/treatment Phase
Duchenne Muscular Dystrophy Drug: NS-065/NCNP-01 Phase 2

Detailed Description:

This is a Phase II, multicenter, open-label, extension study of NS-065/NCNP-01 administered intravenously once weekly for an additional 192 weeks to boys with DMD who complete Study NS-065/NCNP-01-201. This study will evaluate the safety, tolerability, and clinical efficacy of NS-065/NCNP-01 at dose levels of up to 80 mg/kg/week administered by weekly IV infusion over an additional treatment period of 192 weeks or until enrollment in a separate long-term follow up program of NS-065/NCNP-01, whichever is earlier.

Patients who complete the Phase II Dose-finding Study NS-065/NCNP-01-201 are eligible to enroll.
