Key Messages

  • CADTH recommends that Evrysdi should be reimbursed by public drug plans for the treatment of spinal muscular atrophy (SMA) in patients aged 2 months and older, if certain conditions are met.
  • Evrysdi should only be reimbursed if the patient is under the care of a specialist with experience in the diagnosis and management of SMA, it is not used in combination with nusinersen or onasemnogene abeparvovec, and the price is reduced.
  • Evrysdi should only be reimbursed to treat patients aged 2 months to 7 months with genetic documentation of 2 or 3 copies of the survival motor neuron 2 (SMN2) gene or non-ambulatory patients aged 8 months to 25 years with genetic documentation of 2 or 3 copies of the SMN2 gene. Patients are ineligible if they currently require permanent invasive ventilation. After 12 months of treatment, patients should be assessed to ensure clinical benefit.
