Title: A Phase 3, Randomized, Double-Blind, Sham-Procedure Controlled Study to Assess the Clinical Efficacy and Safety of ISIS 396443 Administered Intrathecally in Patients With Infantile-onset Spinal Muscular Atrophy
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.

* Estimated life expectancy \> 2 years from Screening
* Meets age-appropriate institutional criteria for use of anesthesia/sedation, if use is planned for study procedure

Key Exclusion Criteria:

* Have any new or worsening of existing condition which in the opinion of the Investigator would make the participant unsuitable for enrollment, or could interfere with the participant participating in or completing the study.

* Presence of an untreated or inadequately treated active infection requiring systemic antiviral or antimicrobial therapy any time during the screening period
* Clinically significant abnormalities in hematology or clinical chemistry parameters
* Treatment with investigational drug, biological agent, or device within 1-month of Screening or 5 half-lives of study agent, whichever is longer. Treatment with valproate or hydroxyurea within 1 months of screening. Any history of gene therapy or cell transplantation

NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.

* Reside within approximately 9 hours ground-travel distance from a participating study center, for the duration of the study

Key Exclusion Criteria:

* 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

NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.
D: Key Inclusion Criteria:

* Parent or guardian has signed informed consent and, if indicated per participant's age and institutional guidelines, participant has signed informed assent
* Be medically diagnosed with Spinal Muscular Atrophy (SMA)
* Have onset of clinical signs and symptoms consistent with SMA at greater than 6 months of age
* Be able to sit independently, but has never had the ability to walk independently
* Have Motor Function Score (Hammersmith Functional Motor Scale - Expanded) greater than or equal to 10 and less than or equal to 54 at Screening
* Be able to complete all study procedures, measurements and visits and parent or guardian and subject has adequately supportive psychosocial circumstances, in the opinion of the Investigator
* Have an estimated life expectancy of greater than 2 years from Screening, in the opinion of the Investigator
* Meet age-appropriate institutional criteria for use of anesthesia and sedation, if use is planned for study procedures
* For subjects who have reached reproductive maturity, satisfy study contraceptive requirements

Key Exclusion Criteria:

* Respiratory insufficiency, defined by the medical necessity for invasive or non-invasive ventilation for greater than 6 hours during a 24 hour period, at Screening
* Medical necessity for a gastric feeding tube, where the majority of feeds are given by this route, as assessed by the Site Investigator

* History of bacterial meningitis
* Dosing with IONIS-SMN Rx in any previous clinical study
* Prior injury (e.g., upper or lower limb fracture) or surgical procedure which impacts the subject's ability to perform any of the outcome measure testing required in the protocol and from which the subject has not fully recovered or achieved a stable baseline
* 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 subject unsuitable for inclusion
* Treatment with another investigational drug (e.g., oral albuterol or salbutamol, riluzole, carnitine, creatine, sodium phenylbutyrate, et.c), biological agent, or device within 1-month of Screening or 5 half-lives of study agent, whichever is longer. Treatment with valproate or hydroxyurea within 3-months of Screening. Any history of gene therapy, antisense oligonucleotide therapy, or cell transplantation.
* Ongoing medical condition that according to the Site Investigator would interfere with the conduct and assessments of the study. Examples are medical disability (e.g., wasting or cachexia, severe anemia, etc.) that would interfere with the assessment of safety or would compromise the ability of the subject to undergo study procedures.
