Study Endpoints
Primary Endpoints
Number of Participants with Adverse Events (AEs)
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.

Secondary Endpoints
Maximum Plasma concentration (Cmax) of SRP-5051
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
Pre-dose, mid-infusion, end of infusion, post-dose (0.25, 0.5, 1, 2, 4, 8, 12 hours)
