1. What is Kalydeco and what is it used for

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

Kalydeco tablets are indicated:

  • As monotherapy for patients aged 6 years and older with a weight of 25 kg or more with cystic fibrosis (CF) and an R117H mutation in the CFTR gene or one of the following gating mutations in the CFTR gene: G551D, G1244E, G1349D, G178R, G551S, S1251N, S1255P, S549N, or S549R.
  • In combination with tezacaftor/ivacaftor tablets for patients aged 6 years and older with CF who have two F508del mutations in the CFTR gene (homozygous for the F508del mutation) or who have an F508del mutation and a second mutation that results in a reduction in the amount and/or function of the CFTR protein (heterozygous for the F508del mutation with a residual function [RF] mutation). If you have been prescribed Kalydeco to take with tezacaftor/ivacaftor, read the tezacaftor/ivacaftor package leaflet. It contains important information about how to take these two medicines.
  • In combination with ivacaftor/tezacaftor/elexacaftor tablets for patients aged 6 years and older who have CF, with at least one mutation in the CFTR gene that responds to Kalydeco in combination with ivacaftor/tezacaftor/elexacaftor. If you have been prescribed Kalydeco to take with ivacaftor/tezacaftor/elexacaftor, read the ivacaftor/tezacaftor/elexacaftor package leaflet. It contains important information about how to take these two medicines.

  • An increase in liver enzymes in the blood has been seen in some people taking Kalydeco (alone or in combination with tezacaftor/ivacaftor or ivacaftor/tezacaftor/elexacaftor). Tell your doctor right away if you have any of the following symptoms, which may be signs of liver problems:
  • Pain or discomfort in the upper right stomach area (abdomen)
  • Yellowing of the skin or the white part of the eyes
  • Lack of appetite
  • Feeling sick (nausea) or vomiting
  • Dark urine
  • Your doctor will do blood tests to check how your liver is working before and during treatment, especially during the first year and especially if your blood tests have shown that you have had elevated liver enzymes in the past.
  • Depression (including thoughts of suicide and suicidal behavior) has been reported in patients taking Kalydeco, mainly in combination with tezacaftor/ivacaftor or ivacaftor/tezacaftor/elexacaftor, which usually occurs in the first three months of treatment. Tell your doctor right away if you (or someone taking this medicine) experience any of the following symptoms: feeling sad or changed mood, anxiety, feeling unwell emotionally, or thoughts of self-harm or suicide, which may be signs of depression.
  • Tell your doctor if you have or have had kidney problems.
  • If you have two Class I mutations (mutations known not to produce the CFTR protein), you should not take Kalydeco, as it is not expected to respond to this medicine.
  • Kalydeco is not recommended if you have had an organ transplant.
  • Tell your doctor if you are using hormonal contraceptives, for example, women using the contraceptive pill. It may mean that you are more likely to get a skin rash while taking Kalydeco in combination with ivacaftor/tezacaftor/elexacaftor.
  • In some children and adolescents treated with Kalydeco (alone or in combination with tezacaftor/ivacaftor or ivacaftor/tezacaftor/elexacaftor), a cataract (an abnormality in the lens of the eye) has been seen without any effect on vision.
