About This Medication

Genentech Patient Foundation and ENSPRYNG Co-pay Program Patient Guide: How to Get ENSPRYNG (satralizumab-mwge) at Low or No Cost

ENSPRYNG (satralizumab-mwge) is a prescription medication used to treat certain autoimmune conditions like neuromyelitis optica spectrum disorder (NMOSD) in adults and children. The Genentech Patient Foundation and ENSPRYNG Co-pay Program help eligible patients access this important drug at low or no cost, depending on insurance status and financial need.[1][2][6]

About ENSPRYNG and Why Assistance Matters

ENSPRYNG is a biologic therapy given by subcutaneous injection, typically every 4 weeks after initial doses, to reduce relapses in NMOSD, a rare disease affecting the optic nerves and spinal cord. Treatment costs can exceed tens of thousands of dollars annually without help, making patient assistance programs essential for many.[6] Genentech, the manufacturer, offers two main programs:

  • Genentech Patient Foundation: Provides free medication for up to one year (renewable) to uninsured, underinsured, or insured patients with high out-of-pocket costs.[1][7]
  • ENSPRYNG Co-pay Program: Covers co-pays, deductibles, and co-insurance for commercially insured patients, reducing costs to as low as $0 per fill (up to program limits).[program details]

These programs ensure continuity of care, especially since reauthorization is required annually.[program details][7]

Who Qualifies?

Eligibility varies by insurance and income. There are no strict federal poverty level (FPL) cutoffs listed; instead, requirements are tailored:[program details][6]

  • Uninsured patients: Qualify based on household income typically under $150,000 (exceptions apply) and financial need.[6]
  • Insured patients: Must have coverage for ENSPRYNG but face high costs, like an out-of-pocket maximum over 7.5% of yearly income.[6]
  • Commercially insured: Eligible for co-pay help if not on government insurance.[program details]

Key exclusions: Medicare patients generally do not qualify for the Foundation (co-pay programs have limits); patients in Accumulator/Maximizer plans or required to use AFP vendors are ineligible.[4][7]

Income thresholds depend on insurance status, household size, and costs. Use this table as a guide (call for personalized check):
