  1. Initial Approval Criteria1-12

Coverage is provided in the following conditions:

Spinal Muscular Atrophy (SMA) † Ф

  • Patient must not have previously received treatment with SMA gene therapy (i.e., onasemnogene abeparvovec-xioi); AND
  • Patient will not use in combination with other agents for SMA (e.g., onasemnogene abeparvovec, risdiplam, etc.); AND
  • Patient must not have advanced disease (complete limb paralysis, permanent ventilation support, etc.); AND
  • Patient must have the following laboratory tests at baseline and prior to each administration*: platelet count, prothrombin time; activated partial thromboplastin time, and quantitative spot urine protein testing; AND
  • Patient retains meaningful voluntary motor function (e.g., manipulate objects using upper extremities, ambulate, etc.); AND
  • Patient must have a diagnosis of 5q spinal muscular atrophy confirmed by either homozygous deletion of the SMN1 gene or dysfunctional mutation of the SMN1 gene; AND

    • Patient has ≤ 3 copies of the SMN2 gene (Note: Patients with >3 copies of the SMN2 gene will be reviewed on a case-by-case basis); OR

  • Baseline documentation of one or more of the following:
    • Motor function/milestones, including but not limited to, the following validated scales: Hammersmith Infant Neurologic Exam (HINE), Hammersmith Functional Motor Scale Expanded (HFMSE), Children’s Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND), Bayley Scales of Infant and Toddler development Third Ed. (BSID-III), 6-minute walk test (6MWT), upper limb module (ULM), motor function measure 32 (MFM32), revised upper limb module (RULM), etc.
    • Respiratory function tests [e.g., forced vital capacity (FVC), etc.]
