NCT05726994

Brief Summary

This study relies on the hypotheses that (1) exhaled breath is intimately correlated to the patient's lung condition and that (2)the composition of exhaled breath , i.e. the VOCs profile, will be significantly modified from the first days of treatment by CFTR modulators in a or pauci/symptomatic patients such as young children under 12 years old. The non-invasive and longitudinal collection and analysis of exhaled breath may reveal modifications in signaling pathways impacted by these treatments on the very short term. This study is a single-center pilot study.

cystic fibrosis and Kaftrio®

20 children with cystic fibrosis aged 6 to 12 who initiate Kaftrio®

Biological: exhaled breath collectionOther: Data collection

Interventions

Fasting children will be asked to breathe normally through a mouthpiece for the collection and analysis of exhaled breath.

cystic fibrosis and Kaftrio®

Clinical data will be collected in order to seek correlations with the exhaled breath profile.
