The clinical effectiveness of elexacaftor/tezacaftor/ivacaftor (ETI) for people with CF without a F508del variant: A systematic review and meta-analysis.

Background: Access to elexacaftor/tezacaftor/ivacaftor (ETI) for people with cystic fibrosis (PwCF) without a F508del variant is limited due to lack of clinical data supporting efficacy.

Methods: In this systematic review and meta-analysis, we examined patient-level data from studies reporting the clinical response to ETI for PwCF with non-F508del CFTR variants. We searched electronic data sources including Embase, MEDLINE, and CENTRAL from January 1st, 2019 to May 14th, 2024.
