Trial Summary

What is the purpose of this trial?

This trial is testing a medicine called risdiplam, which is taken by mouth. It aims to help infants who have a genetic diagnosis of spinal muscular atrophy (SMA) but are not yet showing symptoms. The medicine works by helping the body make more of a protein that muscles need to stay healthy. The goal is to see if early treatment can prevent or lessen the severity of SMA.
