Interventional
Description of intervention(s) / exposure
Treatment: Drugs - SRP-4045
Treatment: Drugs - SRP-4053
Treatment: Drugs - Placebo

Experimental: SRP-4045 - Participants amenable to exon 45 skipping will receive SRP-4045 IV infusions, weekly, at 30 mg/kg for up to 96 weeks in the double-blinded period. This will be followed by an open-label extension period in which all participants will receive open-label active treatment of SRP-4045 at 30 mg/kg/week IV infusions for 48 weeks (up to Week 144 in the study).

Experimental: SRP-4053 - Participants amenable to exon 53 skipping will receive SRP-4053 IV infusions, weekly, at 30 mg/kg for up to 96 weeks in the double-blinded period. This will be followed by an open-label extension period in which all participants will receive open-label active treatment of SRP-4053 at 30 mg/kg/week IV infusions for 48 weeks (up to Week 144 in the study).

Placebo comparator: Placebo followed by SRP-4045 or SRP-4053 - Participants amenable to exon 45 or 53 skipping will receive SRP-4045 or SRP-4053 placebo-matching IV infusions, weekly, at 30 mg/kg for up to 96 weeks in the double-blinded period. This will be followed by an open-label extension period in which all participants will receive open-label active treatment of SRP-4045 or SRP-4053 at 30 mg/kg/week IV infusions for 48 weeks (up to Week 144 in the study).

Change From Baseline in the North Star Ambulatory Assessment (NSAA) Total Score at Week 96
Assessment method [5] 0 0
The NSAA is a clinician administered scale that rates the participant's performance on various functional activities. During this assessment, participants will be asked to perform 17 different functional activities, including a 10 meter walk/run, rising from a sit to standing, standing on 1 leg, climbing a box step, descending a box step, rising from lying to sitting, rising from the floor, lifting the head, standing on heels, and jumping. Participants will be graded as follows: 2 = achieves goal without any assistance; 1 = modified method but achieves goal independent of physical assistance from another person; and 0 = unable to achieve goal independently. NSAA Total Score ranges from 0 to 34, with a score of 34 implying normal function.
