Descrizione dettagliata
This Phase 2, multi-center, open-label extension study is designed to assess the long-term safety, tolerability, and functional efficacy of weekly intravenous doses of BMN 351 administered to participants with Duchenne muscular dystrophy (DMD) amenable to exon 51 skipping in the Phase 1/2 study, 351-201. Up to 18 participants ages 4 through 23 at baseline will enroll in the trial after completing 351-201.
The first visit for this study is the same as the final visit of 351-201. To be eligible for this study, potential participants must satisfy the eligibility criteria described in the protocol.

Sperimentale: BMN 351
Participants from 351-201 enrolling in 351-202 will initially receive BMN 351 at the dose level at which they completed 351-201.
Once all 351-201 participants have completed their Week 25 visit in 351-202, available safety and PD data will be analyzed and a single optimal dose level will be selected for 351-202.
All participants from 351-201 will transition to that dose level at their next applicable visit.
|
Anti-sense Oligonucleotide BMN 351 will be administered intravenously
