FDA approves gene therapy
The US Food and Drug Administration has approved a new gene therapy for spinal muscular atrophy (SMA), a neurological disorder that can lead to progressive muscle weakness and in the most severe cases, death. The therapy, Itvisma (onasemnogene abeparvovec), has the same active ingredient as the gene therapy Zolgensma, but formulated at a different concentration. Zolgensma was approved by the FDA in 2019 to treat paediatric patients with SMA. The newest therapy extends the treatment group to older individuals with a confirmed mutation in the survival motor neuron 1 (SMN1) gene.
