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.

Outcome Measures
Primary Outcomes (1)
Time to Death or Respiratory Intervention
The time was the age of the participant at the first occurrence of either a respiratory intervention or death. Respiratory intervention was defined as invasive or noninvasive ventilation for ≥6 hours/day continuously for 7 or more days OR tracheostomy.
Screening up to Day 2891
Secondary Outcomes (27)
Proportion of Participants Developing Clinically Manifested Spinal Muscular Atrophy (SMA)
At 13 and 24 months of age
Percentage of Participants Alive
Up to 8 years of age
Percentage of Participants Who Attained Motor Milestones Assessed as Part of the Hammersmith Infant Neurological Examination (HINE)
Day 700
Percentage of Participants Who Attained Motor Milestones as Assessed by World Health Organization (WHO) Criteria
Baseline up to Day 2891

Eligibility Criteria
You may qualify if:
- Age ≤ 6 weeks at first dose.
- Genetic documentation of 5q SMA homozygous gene deletion or mutation or compound heterozygous mutation.
- Genetic documentation of 2 or 3 copies of survival motor neuron 2 (SMN2).
- Ulnar compound muscle action potential (CMAP) ≥ 1 mV at Baseline.
- Gestational age of 37 to 42 weeks for singleton births; gestational age of 34 to 42 weeks for twins.
- Meet additional study related criteria.
You may not qualify if:
- Hypoxemia (oxygen saturation \<96% awake or asleep without any supplemental oxygen or respiratory support).
- Any clinical signs or symptoms at Screening or immediately prior to the first dosing (Day 1) that are, in the opinion of the Investigator, strongly suggestive of SMA.
- Clinically significant abnormalities in hematology or clinical chemistry parameters.
- Treatment with an investigational drug given for the treatment of SMA biological agent, or device. Any history of gene therapy, prior antisense oligonucleotide (ASO) treatment, or cell transplantation.
- Meet additional study related criteria.
