Effect of VX-770 in Persons with Cystic Fibrosis and the G551D- <i>CFTR</i> Mutation

Abstract

This study to evaluate the safety and adverse-event profile of VX-770 showed that VX-770 was associated with within-subject improvements in CFTR and lung function. These findings provide support for further studies of pharmacologic potentiation of CFTR as a means to treat cystic fibrosis.
