Kaftrio contains three active principles:ivacaftor, tezacaftor and elexacaftor. This medication helps lung cells function better in some patients with cystic fibrosis (CF). CF is a hereditary condition in which the lungs and digestive system can become obstructed with thick and sticky mucus.

Kaftrio taken with ivacaftor is forpatients aged 6or older who suffer from CF withat least one F508del mutationin the CFTR gene(cystic fibrosis transmembrane conductance regulator).Kaftriois designed as a long-term treatment.

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

Kaftrio is usually taken with another medication,ivacaftor. Ivacaftor makes the protein function better while tezacaftor and elexacaftor increase the amount of protein on the cell surface.
