Sarah's Story: A 34-year-old teacher from Charlotte with confirmed HAE Type I who's been managing breakthrough attacks despite being on lanadelumab (Takhzyro) for 18 months. Her specialist wants to switch to garadacimab due to persistent monthly attacks affecting her work and quality of life.

Coverage Requirements for Garadacimab (Andembry)

Note: Garadacimab requires REMS (Risk Evaluation and Mitigation Strategy) compliance, including provider training and patient counseling documentation.

Pre-Authorization Preparation
