A long-term safety study in Brazilian patients with a confirmed diagnosis of Spinal Muscular Atrophy (SMA) treated with Onasemnogene Abeparvovec (Zolgensma®)
This study is a non-interventional Post Authorization Safety Study (PASS) to evaluate long-term, real-world safety data of Brazilian pediatric patients diagnosed with SMA and treated with Onasemnogene Abeparvovec (Zolgensma®) for up to 15 years after the treatment. This study will support the benefit-risk assessment of Onasemnogene Abeparvovec in the approved indications and may also allow for detection of new safety signals and provide further guidance on the management of safety risks associated with Onasemnogene Abeparvovec to patients/caregivers, health care providers (HCPs) and treating physicians, as required by Brazilian Health Authority ANVISA as a conditional measure for granting Zolgensma®'s authorization.

The study population will consist of approximately 50 Brazilian pediatric patients with SMA who were treated with Onasemnogene Abeparvovec (Zolgensma®) in the commercial setting, the closed MAP, or the phase IV OFELIA trial. Patients will be recruited in up to 3 centers in Brazil, over one year of recruitment.

Exclusion Criteria:
Patients currently enrolled in any interventional clinical trial** other than the phase IV OFELIA trial will be excluded from the study.

Started Nov 2023 (actual). Primary completion is estimated for Jan 2042, 217 months after the start.
Of 38 observational studies under Muscular Atrophy, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 66. This study's planned 217 months is above that.
Since we started tracking on Sep 25, 2026, the dates moved once, on Nov 10, 2026: primary completion Sep 2038 → Jan 2042 and completion Sep 2038 → Jan 2042.
