Study Summary

The primary objective is to examine the clinical efficacy of multiple doses of nusinersen (ISIS 396443) administered intrathecally to participants with Infantile-Onset Spinal Muscular Atrophy (SMA). The secondary objectives are to examine the safety and tolerability of multiple doses of nusinersen administered intrathecally to participants with infantile-onset SMA and to examine the cerebral spinal fluid (CSF) and plasma Pharmacokinetics (PK) of multiple doses of nusinersen administered intrathecally to participants with infantile-onset SMA.

Primary Outcome

Section 2 of HINE consists of 8 independent milestone categories. Within each of these categories, participants can progress from complete absence of a motor ability (the lowest level in each category) through multiple milestones (2 to 4 levels in each category) to the highest level within the category. Overall, there are a total of 26 milestones that can be achieved across the 8 categories. Improvement was defined as any of the following: 1. An increase from baseline of 2 milestones or more, or
