Primary Outcome Measures :
  1. Number of Patients With Adverse Events (AEs), Serious Adverse Events (SAEs) and Deaths as a Measure of Safety and Tolerability [ Time Frame: After 78 days in Part A and after 85 days in Part B. ]
    Safety was monitored throughout the study.

  2. Number of Mild, Moderate and Severe Adverse Events as a Measure of Safety and Tolerability [ Time Frame: After 78 days in Part A and after 85 days in Part B. ]
    Safety was monitored throughout the study.

  3. Mean Percent Change From Baseline in Thigh Muscle Volume in Part B, Cohort 5 [ Time Frame: Baseline, Day 85 ]
    Thigh muscle volume was assessed by magnetic resonance imaging (MRI). Change from baseline was calculated from the ratio of the post-baseline mean value to the baseline mean value: [(Day 85/baseline) - 1)] x 100. A positive change from baseline indicates improvement.


Secondary Outcome Measures :
  1. Mean Change From Baseline in Score on the Adult Myopathy Assessment Tool (AMAT) in Part B, Cohort 5 [ Time Frame: Baseline, Day 85 ]
    The AMAT rated physical function and muscle endurance, with higher scores indicating better performance. The tool includes 7 timed functional tasks rated on a scale from 0 - 21 and 6 endurance tasks rated on a scale from 0 - 24. The range for the total score was from 0 (worst) to 45 (best). A positive change from baseline indicates improvement.
