Spinal muscular atrophy type 1 (SMA1) is a rare neuromuscular disease in which 75 percent of affected children die or require permanent ventilation by 13.6 months. Researchers recently published the long-term outcomes of patients who received the investigational drug AVXS-101 – an adeno-associated virus serotype 9 mediated gene replacement therapy.
Twelve children aged 1 to 8 months were treated and followed for 24 months. Longer-term follow up results are included as available for motor milestones.
Notably, for motor milestones, the patient who was the oldest at treatment achieved fewer milestones than those treated at younger ages.
