Brief Summary
The primary objective of the study was to evaluate the safety and tolerability of VX-809 in participants with cystic fibrosis (CF) who are homozygous for the F508del mutation on the CF transmembrane conductance regulator (CFTR) gene.

Outcome Measures
Primary Outcomes (1)
Safety and Tolerability Based on Adverse Events (AEs)
AE: any untoward medical occurrence in a participant during the study; the event does not necessarily have a causal relationship with the treatment. This includes any newly occurring event or previous condition that has increased in severity or frequency after the informed consent form is signed. AE includes serious as well as Non-serious AEs. Serious adverse event (SAE) (subset of AE): medical event or condition, which falls into any of the following categories, regardless of its relationship to the study drug: death, life threatening adverse experience, in-patient hospitalization/prolongation of hospitalization, persistent/significant disability or incapacity, congenital anomaly/birth defect, important medical event. Number of participants with AEs and SAEs are reported. An AE that started at or after initial dosing of study drug, or increased in severity after initial dosing of study drug visit is considered treatment-emergent.
Up to 14 days after last dose (last dose = Day 28)
Secondary Outcomes (9)
Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) at Day 28
