-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs) | An AE is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. 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. | Day 0 up to End of Treatment (2 Years) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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. | Baseline, Day 63 and Every 4 Months Up to End of Treatment (2 years) | 
| Hammersmith Infant Neurological Examination (HINE) Section 2 Scores | Section 2 of the HINE is used to assess motor milestones of the participants. It is composed of 8 motor milestone categories: voluntary grasp, ability to kick in supine position, head control, rolling, sitting, crawling, standing, and walking. | Baseline, Day 63 and Every 4 Months Up to End of Treatment (2 years) | 
| Number of Participants with Ventilatory Support |  | Baseline, Day 63 and Every 4 Months Up to End of Treatment (2 years) | 
| Plasma Concentrations of Nusinersen Sodium Injection |  | Pre-dose and multiple time points post-dose on Day 0, post-dose on Day 28 and pre-dose every 4 months up to end of treatment (2 years) | 
| Cerebrospinal Fluid (CSF) Concentrations of Nusinersen Sodium Injection |  | pre-dose on Day 0, Day 63, and Every 4 Months Up to End of Treatment (2 years) |
