A Phase 3, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study to Evaluate the Efficacy and Safety of VX-770 in Subjects With Cystic Fibrosis and the G551D Mutation
In Brief
A Phase 3 clinical trial evaluating Ivacaftor and Placebo for Cystic Fibrosis. Completed, enrolled 167 participants across 65 sites in 8 countries.
Detailed Summary
The purpose of this study was to evaluate the efficacy and safety of ivacaftor in subjects with cystic fibrosis aged 12 years and older who have the G551D mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Ivacaftor is a potent and selective CFTR potentiator of wild-type, G551D, F508del, and R117H forms of human CFTR protein. Potentiators are pharmacological agents that increase the chloride ion transport properties of the channel in the presence of cyclic AMP-dependent protein kinase A (PKA) activation.
