En undersøgelse af Risdiplam hos deltagere med type I og type II spinal muskelatrofi (SMA)

1. oktober 2026 opdateret af: Hoffmann-La Roche

En ikke-interventionel, multicentrisk undersøgelse af resultaterne af Risdiplam hos patienter med spinal muskelatrofi type I og type II

This multicenter, non-interventional, prospective study with a retrospective component aims to evaluate the real-world clinical outcomes, safety profile, and motor function improvements of Risdiplam treatment in participants with Type I and Type II Spinal Muscle Atrophy over 24 months of treatment.

The study will allow retrospective collection of medical history data and previous participants visits from the medical records.

Tidsramme
Change From Index Date in Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP-INTEND) Score at Month 12
Tidsramme: Baseline, Month 12

CHOP-INTEND assessment is performed for participants aged <2 years or aged >2 years who are not able to sit > 10 seconds as defined by the World Health Organization (WHO). Information regarding the 16 items in the CHOP-INTEND motor assessment are to be collected. It includes both active movements, spontaneous or goal-oriented items and of reflexive movements. It assesses head, neck, and trunk as well as proximal and distal limb strength. The score ranges from 0-64, higher scores representing better motor function outcomes.

The index date (D1) is when the participant was administered the first dose of Risdiplam.

Baseline, Month 12
Change From Index Date in Hammersmith Functional Motor Scale Expanded (HFMSE) Score at Months 12
Tidsramme: Baseline, Months 12

HFMSE assessment is performed for participants who are ≥ 2 years and are sitters or walkers. Items on the original HFMS were expanded to capture higher functioning in SMA patients using 13 relevant additional items adapted from the gross motor function measure (GMFM) with their scoring adapted to a three-point scale as in the original HFMS. The score ranges between 0 - 66, a higher score indicates a higher level of function.

The index date (D1) is when the participant was administered the first dose of Risdiplam.
