An SAE is any untoward medical occurrence that at any dose results in death, places the participant at immediate risk of death, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, results in a congenital anomaly/birth defect, or is a medically important event.

Time frame: Day 0 up to End of Treatment (2 Years)

Secondary Outcomes

Percentage of Participants who Achieved World Health Organization (WHO) Motor Milestone

WHO Multicentre Growth Reference Study (MGRS), a component to assess gross motor development and is usually assessed in terms of age of achievement of motor milestones. Six distinct gross motor milestones criteria are as follows: sitting without support, hands-and-knees crawling, standing with assistance, walking with assistance, standing alone, and walking alone.

Time frame: Baseline, Day 63 and Every 4 Months Up to End of Treatment (2 years)

Time frame: Baseline, Day 63 and Every 4 Months Up to End of Treatment (2 years)

Number of Participants with Ventilatory Support

Time frame: Baseline, Day 63 and Every 4 Months Up to End of Treatment (2 years)
