Brief Summary

A long-term safety study in Brazilian patients with a confirmed diagnosis of Spinal Muscular Atrophy (SMA) treated with Onasemnogene Abeparvovec (Zolgensma®)

Detailed Description

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.
