Brief Summary:
The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics (PK) of 5 escalating doses of SRP-5051 administered as a single dose to patients with DMD amenable to exon 51 skipping treatment.

Condition or disease Intervention/treatment Phase
Muscular Dystrophy, Duchenne Drug: SRP-5051 Phase 1

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 30 participants
Intervention Model: Sequential Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1 Trial to Evaluate the Safety, Tolerability, and Pharmacokinetics of a Single Dose of SRP-5051 in Patients With Duchenne Muscular Dystrophy Amenable to Exon 51 Skipping Treatment
Actual Study Start Date : December 11, 2017
Estimated Primary Completion Date : January 2019
Estimated Study Completion Date : January 2019

Arm Intervention/treatment
Experimental: SRP-5051
Patients will be sequentially assigned to receive one of the 5 escalating dose levels of SRP-5051 on Day 1.
Drug: SRP-5051
Single dose of SRP-5051 administered as an intravenous (IV) infusion.

Primary Outcome Measures :
  1. Number of Patients with Adverse Events (AEs) [ Time Frame: Up to 14 Weeks ]
    An AE is any untoward medical occurrence in a clinical trial patient, which does not necessarily have a causal relationship with the investigational drug. An AE can, therefore, be any unfavorable and unintended symptom, sign, disease, condition, or test abnormality that occurs during or after administration of the study drug whether or not considered related to the study drug.
