  • A Phase III, randomised, double-blind, sham-procedure controlled study1
  • 126 symptomatic patients with later-onset SMA (symptom onset after 6 months of age)1
  • Patients in this study were deemed most likely to develop Type II or III SMA1
  • Patients were randomised 2:1 to either SPINRAZA® or sham-control, with a length of treatment ranging from 324 to 482 days1
  • Median age of onset of clinical signs and symptoms of SMA: 11 months1
  • Median age at screening: 3 years1
  • Most patients (88%) have 3 copies of the SMN2 gene (8% have 2 copies, 2% have 4 copies, and 2% have an unknown copy number)1
