NCT ID NCT03032172

First seen Nov 01, 2025 · Last updated Apr 29, 2026 · Updated 21 times

Summary

This study looked at how safe and tolerable the drug risdiplam is for people with spinal muscular atrophy (SMA), a genetic disease that weakens muscles. It included 174 adults, children, and infants who had already tried other SMA treatments. Researchers monitored side effects and how the drug moved through the body, aiming to control the disease rather than cure it.
