The expanded French compassionate programme for elexacaftor–tezacaftor–ivacaftor use in people with cystic fibrosis without a F508del CFTRvariant: a real-world study

Elexacaftor–tezacaftor–ivacaftor has been approved in Europe for people with cystic fibrosis with at least one F508del CFTRvariant. Additionally, it is approved by the US Food and Drug Administration (FDA) for people with cystic fibrosis with at least one of 177 rare variants. The aims of this study were to describe the clinical response to elexacaftor–tezacaftor–ivacaftor for people with cystic fibrosis without a F508del CFTRvariant in France and to determine CFTRvariant responsiveness to elexacaftor–tezacaftor–ivacaftor based on the observed clinical response.
