Roche presents new data for Evrysdi at World Muscle Society (WMS) 2021 highlighting new advances for people living with rare neuromuscular disorders

Roche announced data from across its growing neuromuscular portfolio at the World Muscle Society (WMS) Virtual Congress 20 – 24 September 2021. The presentations included additional results from the RAINBOWFISH study, evaluating the efficacy and safety of Evrysdi (risdiplam) in babies with pre-symptomatic spinal muscular atrophy (SMA) from birth to six weeks of age and data.

At WMS 2021, data from the ongoing open label RAINBOWFISH study were presented. Four out of five of those treated with Evrysdi for at least 12 months achieved standing and walking independently within the World Health Organization windows for healthy children. In addition, all five babies maintained the ability to swallow and were able to feed exclusively orally after 12 months of treatment. Previously reported results showed that babies treated with Evrysdi for at least 12 months achieved Hammersmith Infant Neurological Examination (HINE-2) motor milestones, with 100% (n=5) able to maintain head control, sitting upright, rolling and crawling.

These data further add to the growing body of evidence supporting Evrysdi’s efficacy in a broad patient population. More than 4,000 patients have been treated with Evrysdi in clinical trials, compassionate use, and real-world settings.
