Kalydeco
IVACAFTOR
Indications and usage 1 INDICATIONS AND USAGE KALYDECO is indicated for the treatment of cystic fibrosis (CF) in patients aged 1 month and older who have at least one mutation in the CFTR gene that is responsive to ivacaftor potentiation based on clinical and/or in vitro assay data [see Clinical Pharmacology (12.1) and Clinical Studies (14) ] .
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.

KALYDECO is a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator indicated for the treatment of cystic fibrosis (CF) in patients aged 1 month and older who have at least one mutation in the CFTR gene that is responsive to ivacaftor based on clinical and/or in vitro assay data. ( 12.1 , 14 ) 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.

Monitoring
- • 5 WARNINGS AND PRECAUTIONS Elevated transaminases (ALT or AST): Transaminases (ALT and AST) should be assessed prior to initiating KALYDECO, every 3 months during the first year of treatment, and annually thereafter.
- • In patients with a history of transaminase elevations, more frequent monitoring of liver function tests should be considered.
- • Patients who develop increased transaminase levels should be closely monitored until the abnormalities resolve.
- • Interrupt dosing in patients with ALT or AST of greater than 5 times the upper limit of normal (ULN).
Interaction Notes
- • 7 DRUG INTERACTIONS Potential for other drugs to affect ivacaftor CYP3A inhibitors: Reduce KALYDECO dosage in patients aged 6 months and older when co-administered with strong CYP3A inhibitors (e.g., ketoconazole) or moderate CYP3A inhibitors (e.g., fluconazole).
- • KALYDECO is not recommended in patients aged 1 month to less than 6 months when co-administered with strong or moderate CYP3A inhibitors.
- • Avoid food or drink containing grapefruit.
- • ( 2.4 , 7.1 ) 7.1 Inhibitors of CYP3A Ivacaftor is a sensitive CYP3A substrate.
