Elexacaftor (VX-445) is a next-generation cystic fibrosis transmembrane conductance regulator (CFTR) corrector. It received FDA approval in October 2019 in combination with tezacaftor and ivacaftor as the combination product Trikafta for the treatment of cystic fibrosis in patients aged ≥ 12 years who have ≥ 1 F508del mutation in the CFTR gene. Trikafta™ has been developed by Vertex Pharmaceuticals Inc. to treat patients with the most common cystic fibrosis mutation (F508del). Its use has been associated with statistically significant and/or clinically meaningful improvements in lung function and respiratory-related quality of life compared with comparator regimens (placebo or ivacaftor/tezacaftor) in multinational phase II and III studies. Elexacaftor and tezacaftor bind to different sites on the CFTR protein and have an additive effect in facilitating the cellular processing and trafficking of select mutant forms of CFTR (including F508del-CFTR) to increase the amount of CFTR protein delivered to the cell surface compared to either molecule alone. Ivacaftor potentiates the channel open probability (or gating) of the CFTR protein at the cell surface.

Approved Use

TRIKAFTA is a combination of ivacaftor, a CFTR potentiator, tezacaftor, and elexacaftor indicated for the treatment of cystic fibrosis (CF) in patients aged 6 years and older who have at least one F508del mutation in the CFTR gene or a mutation in the CFTR gene that is responsive based on in vitro data.
