- Time to death or respiratory intervention [ Time Frame: Up to Day 2891 ]The time will be the age of the participant at the first occurrence of either a respiratory intervention or death. Respiratory intervention is defined as invasive or noninvasive ventilation for ≥6 hours/day continuously for 7 or more days OR tracheostomy.
- Percentage of participants developing clinically manifested spinal muscular atrophy (SMA) [ Time Frame: At 13 and 24 months of age ]
- Percentage of participants alive [ Time Frame: At 13 months, and 2, 3, 4, 5, 6, 7 and 8 years of age ]
- Percentage of participants who attained motor milestones assessed as part of the Hammersmith Infant Neurological Examination (HINE) [ Time Frame: At 13 and 24 months of age ]
- Percentage of participants who attained motor milestones as assessed by World Health Organization (WHO) criteria [ Time Frame: Up to Day 2891 ]
- Change from Baseline in the Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND) motor function scale [ Time Frame: Up to Day 2891 ]
- Change from Baseline in Hammersmith Functional Motor Scale - Expanded (HFMSE) [ Time Frame: Up to Day 2891 ]
- Change from Baseline in weight for age/length [ Time Frame: Up to Day 2891 ]
- Change from Baseline in head circumference [ Time Frame: Up to Day 2891 ]
- Change from Baseline in chest circumference ratio [ Time Frame: Up to Day 2891 ]
- Change from Baseline in head to chest circumference ratio [ Time Frame: Up to Day 2891 ]

- Incidence of adverse events (AEs) and/or serious adverse events (SAEs) [ Time Frame: Up to Day 2891 ]
- Change from Baseline in clinical laboratory parameters [ Time Frame: Up to Day 2891 ]Assessed by the following laboratory tests: Hematology: red blood cells, hemoglobin, hematocrit, platelets, white blood cells, white blood cell differential, Blood chemistry: total protein, albumin, creatinine, cystatin C, creatine phosphokinase, blood urea nitrogen, total bilirubin (direct and indirect), alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, glucose, calcium, phosphorous, chloride, sodium, potassium. Urinalysis: specific gravity, pH, protein, glucose, ketones, bilirubin, red blood cells, white blood cells, epithelial cells, bacteria, casts, crystals
- Change from Baseline in electrocardiograms (ECGs) [ Time Frame: Up to Day 2891 ]
- Change from Baseline in vital signs [ Time Frame: Up to Day 2891 ]Vital sign will be assessed by: temperature, pulse rate, resting systolic and diastolic blood pressure, and respiratory rate.
- Change from Baseline in neurological examinations [ Time Frame: Up to Day 2891 ]
- Cerebrospinal fluid (CSF) and plasma Nusinersen concentrations [ Time Frame: Up to Day 2801 ]
