Treatment of cystic fibrosis (CF) in patients ≥2yrs who have one mutation in the CFTR gene that is responsive to ivacaftor potentiation based on clinical and/or in vitro assay data.
Adults and Children:
<2yrs: not recommended. Oral granules should be mixed with 1 tsp (5mL) of soft-food or liquid (eg, yogurt, applesauce, milk, or juice) and completely consumed. Take with fat-containing food (eg, eggs, butter, peanut butter, cheese pizza, dairy products). 2–<6yrs: (<14kg): 50mg packet every 12 hours; (≥14kg): 75mg packet every 12 hours. ≥6yrs: 150mg tab every 12 hours. Concomitant strong CYP3A inhibitors: 150mg tab or 50mg packet (<14kg) or 75mg packet (≥14kg) twice weekly. Concomitant moderate CYP3A inhibitors: 150mg tab or 50mg packet (<14kg) or 75mg packet (≥14kg) once daily. Moderate hepatic impairment: 150mg tab or 50mg packet (<14kg) or 75mg packet (≥14kg) once daily. Severe hepatic impairment: 150mg tab or 1 packet once daily or less frequently.
If genotype is unknown, use an FDA-cleared CF mutation test to detect the presence of a CFTR mutation followed by verification with bi-directional sequencing when recommended by the mutation test instructions. Assess ALT/AST levels prior to initiating therapy, every 3 months during the first year of treatment, and annually thereafter. History of ALT/AST elevations: monitor LFTs more frequently. If increased ALT/AST levels develop, monitor closely until abnormalities resolved. Interrupt dosing if ALT/AST is >5xULN; after resolution, consider restarting. Perform baseline and follow-up eye exams. Hepatic impairment. Severe renal impairment or ESRD. Pregnancy. Nursing mothers.
