Outcome

Type Measure Description Time frame Safety issue
Primary Change From Baseline in Peak Oxygen Uptake/Consumption (VO2) Up to Week 16 Change from baseline in peak VO2 up to Week 16 was reported. Baseline up to Week 16
Secondary Change From Baseline in Peak VO2 Up to Week 52 Change from baseline in peak VO2 up to Week 52 was reported. Baseline up to Week 52
Secondary Change From Baseline in Mean Count Per Minute of Daily Physical Activity Measured by Accelerometer (PA-Ac) Up to Week 16 Change from baseline in mean count per minute of daily PA-Ac up to Week 16 was reported. The daily physical activity (counts per min) of the participant was assessed via accelerometer during daytime. The accelerometer was given to the participant at Visit 1, and data was collected for 9 consecutive daily daytime periods after Visit 1 (baseline) to Visit 4 (Week 16). Baseline up to Week 16
Secondary Number of Participants With Treatment-emergent Serious Adverse Events (SAEs) SAE is any AE that results in: death, persistent or significant disability/incapacity, requires inpatient hospitalization or prolongation of existing hospitalization, is life-threatening experience, is a congenital anomaly/birth defect and may jeopardize participant and/or may require medical or surgical intervention to prevent one of the outcomes listed above. Up to 56 weeks
Secondary Number of Participants With Treatment-emergent Adverse Events (AEs) An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. Up to 56 weeks
Secondary Number of Participants With AEs Leading to Premature Discontinuation of Study Treatment Number of participants with AEs leading to premature discontinuation of study treatment was reported. AEs leading to premature discontinuation of study treatment were those with action taken with study drug reported as 'permanently discontinued' by the investigator. Up to 56 weeks
Secondary Change From Baseline in Systolic and Diastolic Arterial Blood Pressure (BP) Change from baseline in systolic and diastolic arterial BP at Week 8, Week 16, Week 32 and Week 52 was reported. Baseline, Week 8, Week 16, Week 32 and Week 52
Secondary Change From Baseline in Pulse Rate Change from baseline in pulse rate at Week 8, Week 16, Week 32 and Week 52 was reported. Baseline, Week 8, Week 16, Week 32 and Week 52
Secondary Change From Baseline in Oxygen Saturation (SpO2) Change from baseline in SpO2 was reported. Baseline, Week 8, Week 16, Week 32 and Week 52
Secondary Change From Baseline in Body Weight Change from baseline in body weight was reported. Baseline, Week 8, Week 16, Week 32 and Week 52
Secondary Number of Participants With Treatment-emergent Markedly Abnormal Laboratory Values Number of participants with treatment-emergent markedly laboratory abnormal laboratory values were reported. Abnormal values for platelets (LL < 75); Lymphocytes (HH > 4.0); Neutrophils (LL < 1.5); Prothrombin International Normalized Ratio: HH (greater than and equal to [>=] 1.5 upper limit of normal [ULN]), Ratio: HH >= 2.5 ULN); Bilirubin (HH >= 2 ULN); Alkaline Phosphatase (HH > 2.5 ULN); Glomerular Filtration Rate (LL < 60); Glucose (HH > 8.9); Triglycerides (HH > 3.42). Here "HH" refers to values above the normal range, where H stands for "high" and "LL" refers to values below the normal range where L stands for "low". Up to 56 weeks
