ASsessing The REAl-world Safety & Effectiveness of Spinal Muscular Atrophy Participants Treated With Intrathecal Onasemnogene Abeparvovec-brve (OAV101B) (ITVISMA®): A U.S. Pragmatic Multicenter Study (STREAM)
brief summary
The primary purpose is to address critical evidence in the treatment landscape for Spinal Muscular Atrophy (SMA), specifically focusing on the intrathecal formulation of onasemnogene abeparvovec-brve (ITVISMA®). U.S. Pragmatic Multicenter Study (STREAM).
detailed description
STREAM is a prospective, multicentre cohort study that will follow U.S. participants with genetically confirmed SMA who receive a single, intrathecal dose of onasemnogene abeparvovec-brve. All eligible participants are enrolled prior to therapeutic injection. No randomisation, blinding, or placebo control is employed; instead, each participant acts as his or her own baseline comparator. This study will use an exploratory external cohort of patients matched by age, clinical characteristics, treatment history and availability of at least 1 year of pre-treatment medical history. This patient cohort will be based on a database of retrospectively collected electronic medical records data and will be used descriptively to contextualize study outcomes. Bias is minimised through pre-specified endpoints, uniform rater training on motor-function scales, and a detailed statistical analysis plan that stipulates handling of missing data and intercurrent events in advance.
