Eligibility

Inclusion Criteria:

• Has a genetic diagnosis of DMD and an out-of-frame deletion mutation of the DMD gene amenable to exon 51 skipping treatment

• Has been on a stable dose of oral corticosteroids for at least 12 weeks prior to study drug administration with continued dosing of oral corticosteroids while participating in the study*, or has not received corticosteroids for at least 12 weeks prior to study drug administration and will not initiate dosing of oral corticosteroids while participating in the study

Exclusion Criteria:

• Has a left ventricular ejection fraction (LVEF) less than (<) 40 percent (%) based on an echocardiogram (ECHO) performed within 3 months prior to Screening or at the Screening visit

• Has a QT interval corrected with Fridericia's method (QTcF) >= 450 millisecond (msec) on the Screening electrocardiogram (ECG)

• Initiation or change of dosing (except for modifications to accommodate changes in weight) within 12 weeks prior to Screening and while participating in the study for any of the following: angiotensin-converting enzyme (ACE) inhibitors, angiotensin-receptor blocking agents (ARBs), beta-blockers, or potassium

• Requires antiarrhythmic and/or diuretic therapy for heart failure

• Forced vital capacity (FVC) <40% of predicted value within 3 months of Screening or at the Screening visit

• Known kidney disease or had an acute kidney injury within 6 months prior to Screening

• Treatment with eteplirsen or drisapersen within 6 months prior to Screening, or any experimental gene therapy for the treatment of DMD at any time

• Use of any herbal medication/supplement containing aristolochic acid

Other inclusion/exclusion criteria apply.

*The dose of steroids must remain constant except for modifications to accommodate changes in weight.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants with Adverse Events (AEs)	An AE is any untoward medical occurrence in a clinical trial participant, 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.	From signing of informed consent to 12 weeks after the last infusion of SRP-5051 (Up to 14 weeks)
Secondary	Maximum Plasma concentration (Cmax) of SRP-5051	Plasma samples to be collected via peripheral venipuncture from the contralateral arm used for drug infusion.	Pre-dose, mid-infusion, end of infusion, post-dose (0.25, 0.5, 1, 2, 4, 8, 12 hours)
Secondary	Area under the plasma concentration versus time curve (AUC) of SRP-5051	Plasma samples to be collected via peripheral venipuncture from the contralateral arm used for drug infusion.	Pre-dose, mid-infusion, end of infusion, post-dose (0.25, 0.5, 1, 2, 4, 8, 12 hours)
