A Study of the Effects of Lumacaftor/Ivacaftor (LUM/IVA) on Exercise Tolerance in Subjects With Cystic Fibrosis (CF), Homozygous for the F508del-CFTR Mutation

Summary

This is a Phase 4, randomized, double-blind, placebo-controlled, parallel-group study in subjects aged 12 years and older with CF who are homozygous for the F508del-CFTR mutation. This study is designed to evaluate the effect of LUM/IVA on exercise tolerance in subjects with CF, homozygous for the F508del-CFTR mutation.
