    KALYDECO® (ivacaftor) oral granules now approved for children age 2 years to less than 6

    Indications and Usage

    KALYDECO is a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator indicated for the treatment of cystic fibrosis (CF) in patients age 2 years and older who have one of the following mutations in the CFTR gene: G551D, G1244E, G1349D, G178R, G551S, S1251N, S1255P, S549N, or S549R.

    KALYDECO is indicated for the treatment of CF in patients age 2 years and older who have an R117H mutation in the CFTR gene.

    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.

    Limitation of Use:

    KALYDECO is not effective in patients with CF who are homozygous for the F508del mutation in the CFTR gene.

    Please see Important Safety Information below.

CFTR, cystic fibrosis transmembrane conductance regulator.



Indications and Usage

KALYDECO (ivacaftor) is a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator indicated for the treatment of cystic fibrosis (CF) in patients age 2 years and older who have one of the following mutations in the CFTR gene: G551D, G1244E, G1349D, G178R, G551S, S1251N, S1255P, S549N, or S549R.

KALYDECO is indicated for the treatment of CF in patients age 2 years and older who have an R117H mutation in
the CFTR gene.

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.

Limitation of Use:

KALYDECO is not effective in patients with CF who are homozygous for the F508del mutation in the CFTR gene.

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. It is recommended that ALT and AST 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, more frequent monitoring of liver function tests should be considered
  • 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 dosing

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 efficacy of KALYDECO in patients with CF younger than 2 years of age have not been studied. The use of KALYDECO in children under the age of 2 years 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

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 (24% vs 16%), oropharyngeal pain (22% vs 18%), upper respiratory tract infection (22% vs 14%), nasal congestion (20% vs 15%), abdominal pain (16% vs 13%), nasopharyngitis (15% vs 12%), diarrhea (13% vs 10%), rash (13% vs 7%), nausea (12% vs 11%), and dizziness (9% vs 1%)
  • The safety profiles for patients with a G1244E, G1349D, G178R, G551S, G970R, S1251N, S1255P, S549N, or S549R mutation enrolled in Trial 4, for patients with an R117H mutation enrolled in Trial 5, and for patients ages 2 to less than 6 years enrolled in Trial 6 were similar to that observed in Trials 1 and 2
