Spinraza in Adult Spinal Muscular Atrophy

This is a prospective, longitudinal, multi-center, observational study designed to evaluate the safety, tolerability, and effectiveness of SPINRAZA® (nusinersen) in ambulatory and non-ambulatory adult patients with SMA. Subjects with SMA II/III that are 18 years to 70 years of age who are planning to initiate treatment with SPINRAZA® (nusinersen) as part of their clinical care plan will be enrolled in this study. This study does not provide SPINRAZA® (nusinersen) or cover costs associated with standard clinical care.These patients will be treated by their respective physicians according to standard clinical practice. Study visits, some of which including standardized assessments of strength and function, will occur at baseline, day 15 after treatment initiation, day 30, day 60, and then 4-month intervals through month 30. After 30 months an additional cohort 2 was added. The approval date was March 13, 2023. The cohort 2 is a one time survey to gain a better understanding of this adult population and their treatment preferences.
