|Spinal Muscular Atrophy 1||Biological: Onasemnogene Abeparvovec-xioi|
This is a long term, safety follow up study of patients in the AVXS-101-CL-101 gene replacement therapy clinical trial for SMA Type 1 delivering onasemnogene abeparvovec-xioi. Patients will roll over from the parent study into this long-term study for continuous safety monitoring for up to 15 years. The last visit of the parent study or early discontinuation from the parent study may serve as the visit at which the informed consent form process is conducted for the AVXS 101-LT-001 long term follow-up safety study. Patients will return annually for follow up study visits for five (5) years, and then will be contacted via phone annually for ten (10) years. Additionally, patient record transfers from their local physician and/or neurologist will be requested in conjunction with the annual study visits and phone contacts for review by the investigator.
If the patient is unable to return to the original investigative site, the sponsor will arrange with the patients' local established physician to serve as an additional investigator to conduct the required assessments.
