1. What is Kalydeco and what is it used for

Kalydeco contains the active substance ivacaftor. Ivacaftor acts on the cystic fibrosis transmembrane conductance regulator (CFTR), a protein that forms a channel on the cell surface that allows particles such as chloride to enter and leave the cell. Due to mutations in the CFTRgene (see below), chloride movement is reduced in people with cystic fibrosis (CF). Ivacaftor helps certain abnormal CFTR proteins to open more frequently to improve chloride entry and exit from the cell.

Kalydeco granules are indicated:

• As monotherapy for the treatment of infants and children 1 month or older with a weight of 3 kg to less than 25 kg with cystic fibrosis (CF) and an R117Hmutation in the CFTRgene or one of the following gate opener mutations in the CFTRgene: G551D, G1244E, G1349D, G178R, G551S, S1251N, S1255P, S549Nor S549R.
• In combination with ivacaftor/tezacaftor/elexacaftor granules in sachet for patients 2 to 6 years old who have CF, with at least one F508delmutation in the CFTRgene. If your child has been prescribed Kalydeco to take with ivacaftor/tezacaftor/elexacaftor, read the package leaflet of ivacaftor/tezacaftor/elexacaftor. It contains important information on how to take these two medicines.

2. What you need to know before your child takes Kalydeco
