Brief Summary:
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 Insert (USPI) in adult and pediatric participants with spinal muscular atrophy (SMA). In this study, participants will be followed for up to 5 years 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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Participants With Adverse Events (AEs), Adverse Events of Special Interest (AESIs), and Serious Adverse Events (SAEs) [ Time Frame: Up to 5 years ]
    An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Pre-existing conditions which worsen during a study are also considered as adverse events.


Secondary Outcome Measures :
  1. Percentage of Participants Considered Improved on the Clinical Global Impression of Change (CGI-C) Scale [ Time Frame: Up to 5 years ]
    The Clinical Global Impression of Change (CGI-C) is used to score a clinician's impression of a participant's change in global health. The CGI-C is a single item measure of change in global health, using seven response options: "very much improved", "much improved", "minimally improved", "no change", "minimally worse", "much worse", and "very much worse". Participants considered as "improved" include responses of "very much improved, "much improved" and "minimally improved".
