Résumé
We recently demonstrated that elexacaftor/tezacaftor/ivacaftor (ETI) improves the lung clearance index (LCI) and abnormalities in lung morphology detected by magnetic resonance imaging (MRI) in adolescent and adult patients with cystic fibrosis (CF). However, real-world data on the effect of ETI on these sensitive outcomes of lung structure and function in school-age children with CF have not been reported. The aim of this study was therefore to examine the effect of ETI on the LCI and the lung MRI score in children with CF and one or two This prospective, observational, multicenter, post-approval study assessed the longitudinal LCI up to 12 months and the lung MRI score before and three months after initiation of ETI. A total of 107 children with CF including 40 heterozygous for F508del and a minimal function mutation (F/MF) and 67 homozygous for F508del (F/F) were enrolled in this study. Treatment with ETI improved the LCI in F/MF children (-1.0; IQR, -2.0 to -0.1; p<0.01) and F/F children (-0.8; IQR, -1.9 to -0.2; p<0.001) from 3 months onwards. Further, ETI improved the MRI global score in F/MF (-4.0; IQR, -9.0 to 0.0; p<0.01) and F/F children (-3.5; IQR, -7.3 to -0.8; p<0.001). ETI improves early abnormalities in lung ventilation and morphology in school-age children with CF and at least one

METHODS
This prospective, observational, multicenter, post-approval study assessed the longitudinal LCI up to 12 months and the lung MRI score before and three months after initiation of ETI.

A total of 107 children with CF including 40 heterozygous for F508del and a minimal function mutation (F/MF) and 67 homozygous for F508del (F/F) were enrolled in this study.
