Official Title: A Double-Blind, Placebo-Controlled, Multi-Center Study With an Open-Label Extension to Evaluate the Efficacy and Safety of SRP-4045 and SRP-4053 in Patients With Duchenne Muscular Dystrophy

Purpose: The main objective of this study is to evaluate the efficacy of SRP-4045 and SRP-4053 compared to placebo in Duchenne muscular dystrophy (DMD) patients with out-of-frame deletion mutations amenable to skipping exon 45 and exon 53 respectively. Additional objectives include evaluation of safety, pharmacokinetics and biomarkers.

Official Title: An Open-Label Safety, Tolerability, and Pharmacokinetics Study of Eteplirsen in Young Patients with Duchenne Muscular Dystrophy Amenable to Exon 51 Skipping

Purpose: This is a multicenter, open-label, dose-escalation study to evaluate the safety, tolerability, PK, and efficacy of once-weekly IV infusions of eteplirsen in approximately 12 male patients, ages 6 months to 48 months (inclusive), who have genotypically confirmed DMD with a deletion mutation amenable to exon 51 skipping.

Official Title: A Randomized, Double-Blind, Placebo-Controlled, Dose-Titration, Safety, Tolerability, and Pharmacokinetics Study Followed by an Open-Label Safety and Efficacy Evaluation of SRP-4045 in Advanced-Stage Patients With Duchenne Muscular Dystrophy Amenable to Exon 45 Skipping

Purpose: The main objective of this first-in-human, dose-titration, and open-label extension study is to assess safety, tolerability, and pharmacokinetics of SRP-4045 in advanced-stage Duchenne muscular dystrophy (DMD) patients with deletions amenable to exon 45 skipping.

Official Title: An Open-Label, Multiple-Dose, Efficacy, Safety, and Tolerability Study of Eteplirsen in Subjects With Duchenne Muscular Dystrophy Who Participated in Study 4658-US-201

Purpose: The primary objective of this study is to assess the ongoing efficacy, safety, and tolerability of an additional 212 weeks of treatment with eteplirsen injection in Duchenne muscular dystrophy (DMD) subjects who have successfully completed the 28 week eteplirsen study: Study 4658-us-201. This study will also evaluate the correlation between biomarkers for DMD and the clinical status of participating DMD subjects.

Official Title: An Open-Label, Multi-Center Study to Evaluate the Safety and Tolerability of Eteplirsen in Patients With Advanced Stage Duchenne Muscular Dystrophy

Purpose: The primary objective of this study is to explore safety and tolerability of eteplirsen in patients with advanced stage Duchenne muscular dystrophy (DMD) who are amenable to exon 51 skipping. The exploratory objectives are to evaluate the effect of eteplirsen on pulmonary function tests (PFTs) and other functional clinical measures.
