1.          What Kaftrio is and what it is used for

 

Kaftrio contains three active substances: ivacaftor, tezacaftor and elexacaftor. The medicine helps lung cells to work better in some patients with cystic fibrosis (CF). CF is an inherited condition in which the lungs and the digestive system can become clogged with thick, sticky mucus.

 

Kaftrio taken with ivacaftor is for patients aged 2 to less than 6 years who have CF, with at least one F508del mutation in the CFTR (cystic fibrosis transmembrane conductance regulator) gene. Kaftrio is intended as a long-term treatment.

 

Kaftrio works on a protein called CFTR. The protein is damaged in some people with CF, if they have a mutation in the CFTR gene.

 

Kaftrio is normally taken with another medicine, ivacaftor. Ivacaftor causes the protein to work better, while tezacaftor and elexacaftor increase the amount of protein at the cell surface.

 

Kaftrio (taken with ivacaftor) helps your child’s breathing by improving his/her lung function. You may also notice that your child does not get ill as often, or that it is easier for your child to gain weight.

 

 

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

 

Do not give your child Kaftrio:

·            If your child is allergic to ivacaftor, tezacaftor, elexacaftor, or any other ingredients of this medicine (listed in section 6).

Talk to your child’s doctor and do not give your child this medicine, if this applies to your child.

 

Warnings and precautions

 

·            Talk to your child’s doctor if your child has liver problems, or have had them previously. Your doctor may need to adjust your child’s dose.

 

·            Your doctor will do some blood tests to check your child’s liver before and during treatment with Kaftrio, especially if your child’s blood tests showed high liver enzymes in the past. Liver enzymes in the blood can increase in patients receiving Kaftrio.

 

Tell your doctor right away if your child has any symptoms of liver problems. These are listed in section 4.

 

·            Depression (including suicidal thoughts and behaviours) has been reported in patients while taking Kaftrio, usually starting within the first three months of treatment. Talk to your doctor straight away if your child experiences any of the following symptoms which may be signs of depression: sad or altered mood, anxiety, feelings of emotional discomfort or thoughts of harming or killing themselves.

 

·            Talk to your child’s doctor if your child has kidney problems, or your child has previously had them.

 

·            Talk to your child’s doctor before starting treatment with Kaftrio if your child has received an organ transplant.

 

·            Your child’s doctor may do eye examinations before and during treatment with Kaftrio. Cloudiness of the eye lens (cataract) without any effect on vision has occurred in some children and adolescents receiving this treatment.

 

Children under 2

Do not give Kaftrio granules to children under the age of 2 years because it is not known if Kaftrio granules are safe and effective in this age group.
