Longitudinal change in FEV 1 in adults with cystic fibrosis treated with elexacaftor-tezacaftor-ivacaftor in France: a prospective observational study
These results suggest that about a third of adults with cystic fibrosis (tissue scarring) who are treated with ETI had a persistent decline in ppFEV 1 . These data emphasise the importance of regular ppFEV 1 monitoring and highlight the need to improve current therapeutic strategies to prevent ppFEV 1 decline.
