Early treatment is a lifeline for infants with SMA

Charlotte J Sumner et al. Nat Med. 2022 Jul.

Abstract

In the Phase 3 SPRINT trial, pre-symptomatic gene therapy demonstrated impressive clinical outcomes in infants with a genetic diagnosis of SMA; long-term safety follow-up of these patients must now be a key priority.

Figure 1.
Figure 1.. Onasemnogene abeparvovec (OA)
an AAV9 SMN gene replacement therapy, is administered as a one-time intravenous injection. Transduction of motor neurons likely results in improved motor neuron development, function, and survival with the potential for near normal attainment of motor milestones. Whether OA remains effective and safe throughout life requires further assessment.
