Targets the genetic root cause of SMA

ZOLGENSMA® (onasemnogene abeparvovec-xioi) is a prescription gene therapy used to treat children less than 2 years old with spinal muscular atrophy (SMA). It targets the genetic root cause of SMA with a one-time-only dose and replaces the function of the missing or nonworking survival motor neuron 1 (SMN1) gene with a new, working copy of a human SMN gene.
