Brief Summary:
The primary objective of the study is to examine the efficacy of multiple doses of Nusinersen administered intrathecally in preventing or delaying the need for respiratory intervention or death in infants with genetically diagnosed and presymptomatic spinal muscular atrophy (SMA). Secondary objectives of this study are to examine the effects of Nusinersen in infants with genetically diagnosed and presymptomatic SMA.

Primary Outcome Measures :
  1. 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.

Secondary Outcome Measures :
  1. Percentage of participants developing clinically manifested spinal muscular atrophy (SMA) [ Time Frame: At 13 and 24 months of age ]
  2. Percentage of participants alive [ Time Frame: At 13 months, and 2, 3, 4, 5, 6, 7 and 8 years of age ]
  3. 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 ]
  4. Percentage of participants who attained motor milestones as assessed by World Health Organization (WHO) criteria [ Time Frame: Up to Day 2891 ]
  5. 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 ]
  6. Change from Baseline in Hammersmith Functional Motor Scale - Expanded (HFMSE) [ Time Frame: Up to Day 2891 ]
  7. Change from Baseline in weight for age/length [ Time Frame: Up to Day 2891 ]
  8. Change from Baseline in head circumference [ Time Frame: Up to Day 2891 ]
  9. Change from Baseline in chest circumference ratio [ Time Frame: Up to Day 2891 ]
  10. Change from Baseline in head to chest circumference ratio [ Time Frame: Up to Day 2891 ]
  11. Change from Baseline in arm circumference ratio [ Time Frame: Up to Day 2891 ]
  12. Incidence of adverse events (AEs) and/or serious adverse events (SAEs) [ Time Frame: Up to Day 2891 ]
  13. 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

  14. Change from Baseline in electrocardiograms (ECGs) [ Time Frame: Up to Day 2891 ]
  15. 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.

  16. Change from Baseline in neurological examinations [ Time Frame: Up to Day 2891 ]
  17. Cerebrospinal fluid (CSF) and plasma Nusinersen concentrations [ Time Frame: Up to Day 2801 ]
