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.
