Summary

This study tested a gene therapy called AVXS-101 in children aged 6 months to 5 years with spinal muscular atrophy (SMA) who could sit but not stand or walk. The goal was to see if the treatment was safe and could help them gain motor skills like standing or walking. The trial was stopped early, but results may still provide insights into treating SMA.
