Background:

Icenticaftor (QBW251) is an orally active CFTR channel potentiator, with EC50s of 79 nM and 497 nM for F508del and G551D CFTR, respectively. Icenticaftor can be used for chronic obstructive pulmonary disease (COPD) and cystic fibrosis research[1].

Icenticaftor (QBW251), an orally bioavailable small molecule CFTR potentiator, can restore CFTR function in specific CFTR genotypes as well as wild-type CFTR[2].

In Sprague-Dawley rats, the pharmacokinetic profile of Icenticaftor is established. After oral administration at a dose of 3 mg/kg, the oral bioavailability is 90%, and AUClast is 20?635 nmol/L•h[1].
