Outcomes

Primary Outcome Measures

Change From Baseline in Time to Stand (TTSTAND) Versus Matched Historical Controls
A primary efficacy endpoint was compared to Baseline of Study 201 (NCT02740972): Time to Stand (TTSTAND)
Change From Baseline in Time to Stand (TTSTAND) Velocity Versus Matched Historical Controls
A primary efficacy endpoint was compared to Baseline of Study 201 (NCT02740972): Time to Stand (TTSTAND) Velocity
Number of Participants With Treatment Related Adverse Events as Assessed by CTCAE v4.0.
For adverse events (AEs) starting in study 201 (NCT02740972) which are not resolved at the time of enrollment into this study 202, any change in outcome or relatedness were reported in study 201. For AEs starting in study 201 which increase in severity or becomes serious after enrollment in this study 202, a new AE was reported in this study. Treatment-emergent AEs (TEAEs) were summarized by dose level. Coding was done by system organ class and preferred term (using the Medical Dictionary for Regulatory Activities (MedDRA)). Level of severity was assessed using the CTCAE grading system.

Secondary Outcome Measures

Change From Baseline in Time to Run/Walk 10 Meters Test (TTRW) Versus Matched Historical Controls
A secondary efficacy endpoint was compared to Baseline of Study 201 (NCT02740972): Time to Run/Walk 10 meters test (TTRW)
Change From Baseline in Time to Run/Walk 10 Meters Test (TTRW) Velocity Versus Matched Historical Controls
A secondary efficacy endpoint was compared to Baseline of Study 201 (NCT02740972): Time to Run/Walk 10 meters test (TTRW) Velocity. The results were converted into velocity (meter/time).
Change From Baseline in Time to Climb 4 Stairs (TTCLIMB) Versus Matched Historical Controls
A secondary efficacy endpoint was compared to Baseline of Study 201 (NCT02740972): Time to Climb 4 stairs (TTCLIMB)
Change From Baseline in Time to Climb 4 Stairs (TTCLIMB) Velocity Versus Matched Historical Controls
A secondary efficacy endpoint was compared to Baseline of Study 201 (NCT02740972): Time to Climb 4 stairs (TTCLIMB) Velocity. The results were converted into velocity (meter/time).
Change From Baseline in North Star Ambulatory Assessment (NSAA) Score Versus Matched Historical Controls
A secondary efficacy endpoint was compared to Baseline of Study 201 (NCT02740972): North Star Ambulatory Assessment (NSAA) score The NSAA is a functional scale devised for use in ambulant children with Duchenne muscular dystrophy (DMD). It consists of 17 activities graded 0 (unable to perform), 1 (performs with modifications), 2 (normal movement). It assesses abilities necessary to remain ambulant that have been found to progressively deteriorate in untreated DMD patients, as well as in other muscular dystrophies such as Becker Muscular Dystrophy. NSAA Total Score ranges from 0 to 34, with a score of 34 implying normal function.
Change From Baseline in Six-Minute Walk Test (6MWT) Versus Matched Historical Controls
A secondary efficacy endpoint was compared to Baseline of Study 201 (NCT02740972): Six-Minute Walk Test (6MWT)
Change From Baseline in Quantitative Muscle Testing (QMT) for Handgrip Versus Matched Historical Controls
A secondary efficacy endpoint was compared to Baseline of Study 201 (NCT02740972): Quantitative Muscle Testing (QMT) for Handgrip For QMT tests, the higher of each of the bilateral scores recorded for each muscle group at each visit were analyzed. QMT tests were analyzed by dominant/non-dominant side. QMT is a well-established method for measuring muscle weakness in neuromuscular disease. Patients will be placed on an examination table with a back-support system to eliminate the need for manual back stabilization. Following a single practice administration, each patient will complete a scored QMT evaluation (perform 2 tests; with the higher of the 2 values used for data analysis). QMT will be performed by recording force in pounds through a direct computer interface with a strain gauge.
