Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

8 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: SRP-5051

Patients will be sequentially assigned to receive 1 of the 5 escalating dose levels of SRP-5051 on Day 1.

Patients who complete the study and continue to meet safety eligibility criteria will have the opportunity to enroll in an open-label extension study to continue to receive SRP-5051.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants with Adverse Events (AEs)
Time Frame: From signing of informed consent to 12 weeks after the last infusion of SRP-5051 (Up to 14 weeks)
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 Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Maximum Plasma concentration (Cmax) of SRP-5051
Time Frame: Pre-dose, mid-infusion, end of infusion, post-dose (0.25, 0.5, 1, 2, 4, 8, 12 hours)
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)
Area under the plasma concentration versus time curve (AUC) of SRP-5051
Time Frame: Pre-dose, mid-infusion, end of infusion, post-dose (0.25, 0.5, 1, 2, 4, 8, 12 hours)
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)
