Study of VX-809 Alone and in Combination With VX-770 in Cystic Fibrosis (CF) Patients Homozygous or Heterozygous for the F508del-CFTR Mutation
A Phase 2, Multicenter, Double-Blinded, Placebo-Controlled, Multiple-Dose Study to Evaluate Safety, Tolerability, Efficacy, Pharmacokinetics, and Pharmacodynamics of VX-809 Alone and in Combination With VX-770 in Subjects With Cystic Fibrosis, Homozygous or Heterozygous for the F508del-CFTR Mutation

The purpose of this study is to evaluate of the safety, efficacy, pharmacokinetics (PK) and pharmacodynamic (PD) effects of VX-809 alone and when coadministered with VX-770. This is the first study to assess the combination of VX-809 and VX-770 in CF subjects homozygous or heterozygous for the F508del-CFTR mutation.

This is a Phase 2, randomized, double-blind, placebo-controlled, multiple-dose study of orally administered VX-809 and VX-770 in CF subjects homozygous or heterozygous for the F508del-CFTR mutation. The primary objectives of the study are to evaluate the safety and tolerability when VX 809 is administered alone and when VX-809 is coadministered with VX-770 and to evaluate the effect of VX-809 administered alone and in combination VX-770 on sweat chloride

Enrollment is planned at clinical sites in the United States, Germany, Belgium, Australia and New Zealand. Up to 240 subjects may be enrolled. The study will be separated into 3 Cohorts. Cohort 1 will enroll 60 subjects. Cohorts 2 will enroll 100 subjects. Cohort 3 evaluating doses higher than Cohort 2, will enroll up to 80 subjects.
