FOR PATIENTS WITH CF AGED 4 MONTHS AND OLDER WITH AT LEAST ONE MUTATION THAT IS RESPONSIVE TO KALYDECO1

CHECK TREATMENT ELIGIBILITY

Enter your patient's mutations below

KALYDECO is a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator 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.

Mutation 1
Mutation 2 (optional)
Eligible

Mutation(s) not recognized. Please check to see if they were entered correctly.

Results

    Most patients have 2 CFTR mutations, 1 for each allele. However, in rare instances, a single allele can have more than 1 mutation. This is called a compound, or complex, mutation.

    To enter 2 or more mutations into 1 entry field, separate them with a semicolon, space, comma, or forward slash. For example, if your patient's genotype is R74WN201M/D1270N and W1282R, use the Mutation 1 field to enter: R74WN201M/D1270N and the Mutation 2 field to enter: W1282R.

    Important Safety Information

    Transaminase (ALT or AST) Elevations

    • Elevated transaminases have been reported in patients with CF receiving KALYDECO. Transaminase elevations were more common in patients with a history of transaminase elevations or in patients who had abnormal transaminases at baseline. ALT and AST should be assessed prior to initiating KALYDECO, every 3 months during the first year of treatment, and annually thereafter. For patients with a history of transaminase elevations, consider more frequent monitoring of liver function tests
    • Patients who develop increased transaminase levels should be closely monitored until the abnormalities resolve. Dosing should be interrupted in patients with ALT or AST of greater than 5 times the upper limit of normal (ULN). Following resolution of transaminase elevations, consider the benefits and risks of resuming KALYDECO

    Indications and Usage

    KALYDECO is a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator 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.

    Concomitant Use With CYP3A Inducers

    • Use of KALYDECO with strong CYP3A inducers, such as rifampin, substantially decreases the exposure of ivacaftor, which may reduce the therapeutic effectiveness of KALYDECO. Co-administration of KALYDECO with strong CYP3A inducers, such as rifampin, rifabutin, phenobarbital, carbamazepine, phenytoin, and St. John's wort is not recommended

    Cataracts

    • Cases of non-congenital lens opacities/cataracts have been reported in pediatric patients treated with KALYDECO. Baseline and follow-up ophthalmological examinations are recommended in pediatric patients initiating KALYDECO treatment

    Pediatric Use

    • The safety and effectiveness of KALYDECO in patients with CF younger than 4 months of age have not been studied. The use of KALYDECO in children under the age of 4 months is not recommended

    Serious Adverse Reactions

    • Serious adverse reactions, whether considered drug-related or not by the investigators, which occurred more frequently in patients treated with KALYDECO included abdominal pain, increased hepatic enzymes, and hypoglycemia

    Most Common Adverse Reactions

    • The most common adverse reactions in patients with a G551D mutation in the CFTR gene (Trials 1 and 2) with an incidence of ≥8% and at a higher incidence for patients treated with KALYDECO (N=109) than for placebo (N=104) were headache, oropharyngeal pain, upper respiratory tract infection, nasal congestion, abdominal pain, nasopharyngitis, diarrhea, rash, nausea, and dizziness
    • The safety profiles for patients with additional approved mutations enrolled in Trials 4, 5, and 7; and for patients aged 2 to less than 6 years enrolled in Trial 6; and for patients aged 4 months to less than 24 months enrolled in Trial 8; were similar to that observed in Trials 1 and 2
