Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A multi-center, longitudinal, prospective, non-comparative study to investigate the long-term safety and effectiveness of risdiplam, prescribed based on clinician judgment as per the Evrysdi® U.S. Package Information (USPI) in adult and pediatric participants with SMA. In this study, participants will be followed for approximately 24 months from enrollment or until withdrawal of consent, loss to follow-up, or death. Participants who discontinue risdiplam may still remain in the study if they agree to continue participating in the follow-up assessments.

An optional sub-study was planned to assess the feasibility, acceptability, and adherence of remote assessment of motor and bulbar functions in participants with SMA using wearable and smartphone-based biosensors. This substudy was withdrawn upon implementation of protocol version 4.

Risdiplam

Participants who are taking risdiplam prescribed based on clinician judgment, as per the Evrysdi® USPI are enrolled in this study.

A Remote Virtual Site option is available in the study allowing enrollment of participants with SMA who are prescribed risdiplam treatment even if their physician is not a participating investigator. A central investigator will be responsible for data collection and data entry for participants who do not have a participating investigator.
