FOR PATIENTS WITH CYSTIC FIBROSIS AGE 1 MONTH* 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 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.
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 R74W/V201M/D1270N and W1282R, use the Mutation 1 field to enter: R74W/V201M/D1270N and the Mutation 2 field to enter: W1282R.
*Use of KALYDECO in patients aged 1 to less than 6 months born at a gestational age less than 37 weeks has not been evaluated
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
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 indicated for the treatment of cystic fibrosis (CF) in patients age 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.
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.

Hypersensitivity Reactions, Including Anaphylaxis
- Hypersensitivity reactions, including cases of anaphylaxis, have been reported in the postmarketing setting. If signs or symptoms of serious hypersensitivity reactions develop during treatment, discontinue KALYDECO and institute appropriate therapy. Consider the benefits and risks for the individual patient to determine whether to resume treatment with KALYDECO
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 treatment with KALYDECO
ADVERSE REACTIONS
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 the 221 patients treated with KALYDECO were headache (17%), upper respiratory tract infection (16%), nasal congestion (16%), nausea (10%), rash (10%), rhinitis (6%), dizziness (5%), arthralgia (5%), and bacteria in sputum (5%)
- The safety profile for the CF patients enrolled in clinical trials (Trials 3-8) was similar to that observed in the 48-week, placebo-controlled trials (Trials 1 and 2)
USE IN SPECIFIC POPULATIONS
Pediatric Use
- The safety and effectiveness of KALYDECO in patients with CF younger than 1 month of age have not been established. The use of KALYDECO in children under the age of 1 month is not recommended
- Use of KALYDECO in patients aged 1 to less than 6 months born at a gestational age less than 37 weeks has not been evaluated
