Full title

A Phase 3 Study Evaluating the Safety, Tolerability, and Pharmacokinetics of Kaftrio® in children with cystic fibrosis 2 to 5 years old

Study details

This study is to learn more about the safety of taking Kaftrio® (elexacaftor in combination with tezacaftor and ivacaftor) and how well it works in 2- to 5-year-olds with CF. All three of the medicines which make up Kaftrio® are called CFTR modulators. CFTR modulators help the faulty CFTR protein to function properly.

Everyone in the study will receive the study medications. Study participants will be asked to visit the CF clinic around 8 times over 6 months (24 weeks), with an additional follow-up visit approximately 4 weeks after finishing the study medications. During these visits, the research team will look at how the study medications are affecting overall health as well as specific assessments to check lung, pancreas and kidney functions. Bloods and other samples will be collected at some of the visits.


Study results

This study found that Kaftrio was generally safe and well tolerated in children aged 2 to 5 years. These findings are consistent with studies in older age groups.

In this study, children taking Kaftrio had meaningful improvements in CFTR function and lung function. These results support the use of ELX/TEZ/IVA in children with CF who are as young as 2 years of age.
