Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Baseline for the North Star Ambulatory Assessment (NSAA) Total Score	The NSAA is a functional scale specifically designed for ambulant boys with Duchenne muscular dystrophy (DMD) that can provide information about motor function. The NSAA is a 17-item test of standing, ability to transition from lying to sitting, sitting to standing, and other mobility assessments. Each of the 17 items is evaluated on an ordinal scale of 0-2: 0 = unable to achieve independently, 1 = modified method but achieves goal independent of physical assistance from another, or 2 = normal with no obvious modification of activity. Total score range is 0 to 34. Higher scores reflect better performance.	Baseline
Primary	Change From Baseline in the North Star Ambulatory Assessment (NSAA) Total Score at Week 48	The NSAA is a functional scale specifically designed for ambulant boys with Duchenne muscular dystrophy (DMD) that can provide information about motor function. The NSAA is a 17-item test of standing, ability to transition from lying to sitting, sitting to standing, and other mobility assessments. Each of the 17 items is evaluated on an ordinal scale of 0-2: 0 = unable to achieve independently, 1 = modified method but achieves goal independent of physical assistance from another, or 2 = normal with no obvious modification of activity. Total score range is 0 to 34. Higher scores reflect better performance. A positive change from baseline indicates an improvement. Based on the mixed-effect model of repeated measures (MMRM).	Baseline, Week 48
Secondary	Baseline Time for 4 Stair Climb	The time to complete the 4 stair climb was measured at baseline.	Baseline
Secondary	Change From Baseline at Week 48 in 4 Stair Climb Velocity (4SCV)	4SCV was calculated as the ratio of the number of stairs climbed (4) divided by the number of seconds taken to complete the 4-stair climb. The results were converted into velocity (distance/time). A positive change from baseline indicates an improvement. Based on the mixed-effect model of repeated measures (MMRM).	Baseline, Week 48
Secondary	Baseline for the Time to Stand From Supine	The time required for a participant to stand from supine position. A longer time reflects a worse outcome.	Baseline
Secondary	Change From Baseline at Week 48 in Stand From Supine Velocity	The time required for a participant to stand from supine position. A longer time reflects a worse outcome. A negative change from baseline indicates an improvement. Based on the mixed-effect model of repeated measures (MMRM).	Baseline, Week 48
Secondary	Baseline Time for 10 Meter Walk/Run	The time required for a participant to run or walk a distance of 10 meters as quickly as possible. A longer time reflects a worse outcome.	Baseline
Secondary	Change From Baseline at Week 48 in 10 M Walk/Run Velocity	The time required for a participant to run or walk a distance of 10 meters as quickly as possible calculated as velocity (distance/time). A positive change from baseline indicates an improvement. Based on the mixed-effect model of repeated measures (MMRM).	Baseline, Week 48
Secondary	Baseline for the Pediatric Outcome Data Collection Instrument (PODCI) Transfer and Basic Mobility Subscale	The PODCI is designed to be completed by the parent/guardian of a child who has knowledge of the child's conditions. The Transfer and Basic Mobility scale is one of the subscales of the PODCI. The results are standardized into a scale of 0-100 with a higher score reflecting better performance.	Baseline

Secondary	Change From Baseline at Week 48 in Proximal Lower Extremity Flexor Strength	Proximal lower extremity flexor (knee extension and knee flexion) strength was measured using manual myometry. A higher score reflects a better outcome. A positive change from baseline indicates an improvement.	Baseline, Week 48
Secondary	Baseline for the 6 Minute Walk Distance (6MWD)	The 6MWD measured the distance a participant was able to traverse while walking for 6 minutes. A longer distance reflects a better outcome.	Baseline
Secondary	Change From Baseline at Week 48 in 6 Minute Walk Distance (6MWD)	The 6MWD measured the distance a participant was able to traverse while walking for 6 minutes. A longer distance reflects a better outcome. A positive change from baseline indicates an improvement. Based on the mixed-effect model of repeated measures (MMRM).	Baseline, Week 48
Secondary	Percentage of Participants for Each Clinical Global Impression of Change (CGI-C) Assessment Status at Week 48	The CGI-C was used to assess the participant's overall condition on a 7-point scale, using the status markers "very much improved, much improved, slightly improved, no change, slightly worse, much worse or very much worse" at Week 48 as compared to baseline.	Baseline, Week 48
Secondary	Change From Baseline at Week 48 in 95th Percentile Stride Velocity	Stride velocity was recorded with the ActiMyo device in a subset of the overall study population. The ActiMyo device measures the daily movement and activity levels of the participant. The device consists of two sensors worn on each ankle. A higher velocity reflects a better outcome. A positive change from baseline indicates an improvement.	Baseline, Week 48
Secondary	Number of Participants With Adverse Events (AEs)	An adverse event is any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.	During DB period (48 weeks) and Whole study (up to approximately 34 months)
Secondary	Number of Participants With AEs Leading to Discontinuation	An adverse event is any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. Reported here is the number of participants with AEs that led to study discontinuation.	During DB period (48 weeks) and Whole study (up to approximately 34 months)
