At higher doses, HD-CFTR did not increase CFTR function in healthy control cells above baseline values. This latter observation allowed us to use this vector to benchmark in vitro efficacy testing of CFTR-modulator drugs.In summary, we demonstrate the potential for HD-CFTR to inform in vitro testing and to restore CFTR function to healthy control levels in airway cells with class I or CFTR nonsense mutations.CFTR modulators can correct CFTR function in many individuals with CF; however, the correction is not uniform nor universal. There is potential for an adenoviral CFTR vector to correct class I CFTR mutations and benchmark drug responses in vitro. https://bit.ly/3eim6IP ER -
