KALYDECO (ivacaftor)
Self-Administration - Oral
Indications for Prior Authorization:
- Indicated for the treatment of cystic fibrosis (CF) in patients age 4 months and older who have one mutation in the CFTR gene that is responsive to ivacaftor potentiation based on clinical and/or in vitro assay data
- If the patient's genotype is unknown, an FDA-cleared CF mutation test should be used to detect the presence of a CFTR mutation followed by verification with bi-directional sequencing when recommended by the mutation test instructions for use.
Coverage Criteria:
For diagnosis of cystic fibrosis (CF):
- Dose is appropriate for the patient’s age and weight OR does not exceed 150mg every 12 hours, AND
- Patient is 4 months of age or older, AND
- Patient has a diagnosis of cystic fibrosis (CF) as confirmed by chart note documentation, AND
- Patient has at least one mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene that is responsive to ivacaftor potentiation based on clinical and/or in vitro assay data as detected by an FDA-cleared cystic fibrosis mutation test or a test performed at a Clinical Laboratory Improvement Amendments (CLIA)-approved facility, AND
- Prescribed by or in consultation with a pulmonologist or a specialist affiliated with a CF care center, AND
- Kalydeco is not prescribed concurrently with other CFTR modulators (e.g., Orkambi, Symdeko, Trikafta)
Reauthorization Criteria:
For diagnosis of cystic fibrosis (CF):
- Dose is appropriate for the patient’s age and weight OR does not exceed 150mg every 12 hours, AND
- Documentation of positive clinical response (i.e., improvement in lung function [percent predicted forced expiratory volume in one second {PPFEV1}], decreased number of pulmonary exacerbations) to therapy, AND
- Prescribed by or in consultation with a pulmonologist or a specialist affiliated with a CF care center, AND
- Kalydeco is not prescribed concurrently with other CFTR modulators (e.g., Orkambi, Symdeko, Trikafta)
