Understanding Your Hyrnuo (sevabertinib) Denial

Hyrnuo (sevabertinib) is a HER2-targeted tyrosine kinase inhibitor approved for adults with metastatic non-squamous non-small cell lung cancer (NSCLC) with HER2-activating mutations who have received prior systemic therapy. Insurance denials often require proof of HER2 mutation testing and prior treatment history.

Common Reasons for Denial

  • ! HER2 mutation not documented by approved test
  • ! Prior authorization required
  • ! Prior systemic therapy not documented
  • ! Must try other targeted therapies first
  • ! Specialty tier drug not covered
  • ! Accelerated approval concerns

How We Help

We help you compile your HER2 mutation testing results, prior treatment history, and oncologist recommendations to demonstrate medical necessity for Hyrnuo.

Some Types of Evidence We Can Use For Supporting Your Appeal

Sevabertinib is a selective HER2 tyrosine kinase inhibitor designed to target HER2-activating mutations in NSCLC.

HER2 mutations occur in approximately 2-4% of NSCLC patients and represent an actionable target for precision medicine.

Clinical trials demonstrated meaningful response rates and durable disease control with sevabertinib in pretreated HER2-mutant NSCLC.

Targeted therapy based on tumor genomic profiling represents the standard of care for advanced NSCLC with actionable mutations.
