Elexacaftor/Tezacaftor/Ivacaftor Accelerates Wound Repair in Cystic Fibrosis Airway Epithelium

Background: Cystic fibrosis (CF) airway epithelium shows alterations in repair following damage. In vitro studies showed that lumacaftor/ivacaftor (Orkambi) may favor airway epithelial integrity in CF patients. Our aim was to evaluate the effect of the novel triple combination elexacaftor/tezacaftor...

Sumario:Background: Cystic fibrosis (CF) airway epithelium shows alterations in repair following damage. In vitro studies showed that lumacaftor/ivacaftor (Orkambi) may favor airway epithelial integrity in CF patients. Our aim was to evaluate the effect of the novel triple combination elexacaftor/tezacaftor/ivacaftor (ETI) on wound repair in CF airway epithelial cells. Methods: A tip-based scratch assay was employed to study wound repair in monolayers of CFBE14o- cells overexpressing the F508del mutation. ETI was added during wound repair. Results: ETI efficiently rescued CFTR F508del maturation and activity, accelerated wound closure and increased wound healing rates of the injured CF cell monolayers. Conclusions: The triple corrector/potentiator combination ETI shows promise in ameliorating wound healing of the airway epithelium in F508del patients.
