Brief Summary
The primary objective of the study is to examine the clinical efficacy of nusinersen (ISIS 396443) administered intrathecally (IT) to participants with infantile-onset with infantile-onset spinal muscular atrophy (SMA). The secondary objective of the study is to examine the safety and tolerability of nusinersen administered intrathecally to participants with infantile-onset SMA.

Outcome Measures
Primary Outcomes (2)
Percentage of Motor Milestones Responders
The definition of a motor milestones responder was based on improvement in the motor milestones categories in Section 2 of the Hammersmith Infant Neurological Examination (HINE), with the exclusion of voluntary grasp, as follows: (i) subject demonstrates ≥ 2-point increase in the motor milestones category of ability to kick or achievement of maximal score on that category (touching toes), or a 1-point increase in the motor milestones category of head control, rolling, sitting, crawling, standing, or walking, and (ii) among the motor milestone categories, with the exclusion of voluntary grasp, there are more categories where there is improvement as defined in (i) than worsening. (For the category of ability to kick, worsening is defined as ≥ 2-point decrease or decrease to the lowest possible score of no kicking. For the other categories, worsening is defined as ≥ 1-point decrease.) The lowest possible score for the HINE is 0 (zero), and the highest possible score for the HINE is 28.
assessed at the later of the Day 183, Day 302, or Day 394 study visits
Time to Death or Permanent Ventilation
Estimated proportion of participants who died or required permanent ventilation by a given study day, based on the Kaplan-Meier product-limit method. Time to death or permanent ventilation was defined as either tracheostomy or ≥ 16 hours ventilation/day continuously for \> 21 days in the absence of an acute reversible event. This endpoint was adjudicated by a blinded, independent group of experienced clinicians, the Event Adjudication Committee (EAC), based on review of clinical study data and supporting information. Results are based on all available data.

Eligibility Criteria
You may qualify if:
- Be born (gestational age) between 37 and 42 weeks
- Be medically diagnosed with spinal muscular atrophy (SMA)
- Have Survival Motor Neuron2 (SMN2) Copy number = 2
- Body weight equal to or greater than 3rd percentile for age using appropriate country-specific guidelines
- Be able to follow all study procedures
- Reside within approximately 9 hours ground-travel distance from a participating study center, for the duration of the study
You may not qualify if:
- Hypoxemia (oxygen \[O2\] saturation awake less than 96% or O2 saturation asleep less than 96%, without ventilation support) during screening evaluation
- Clinically significant abnormalities in hematology or clinical chemistry parameters or Electrocardiogram (ECG), as assessed by the Site Investigator, at the Screening visit that would render the participant unsuitable for participation in the study
- Participant's parent or legal guardian is not willing to meet standard of care guidelines (including vaccinations and respiratory syncytial virus prophylaxis if available), nor provide nutritional and respiratory support throughout the study
