December 31, 2021 updated by: Vertex Pharmaceuticals Incorporated

A Phase 3, Open-label Study Evaluating the Long Term Safety and Efficacy of VX-659 Combination Therapy in Subjects With Cystic Fibrosis Who Are Homozygous or Heterozygous for the F508del Mutation

This study will evaluate the long-term safety and tolerability of VX-659 in triple combination (TC) with tezacaftor (TEZ) and ivacaftor (IVA) in subjects with cystic fibrosis (CF) who are homozygous or heterozygous for the F508del mutation.

From Baseline up to Week 96 (Study 659-105)
Number of Participants With at Least One PEx for Participants From the Parent Study 659-102
Time Frame: From Baseline up to Week 96 (Study 659-105)
PEx was defined as treatment with new or changed antibiotic therapy (intravenous, inhaled, or oral) for at least 4 sinopulmonary signs/symptoms. The time-to-first-PEx data were planned to be estimated using the Kaplan-Meier (KM) method. However, because way less than 50% of participants had events, median time-to-first event data were not estimable. Instead, the number of participants with at least one PEx event was assessed and reported separately for those in Placebo - VX-659/TEZ/IVA category (participants who received placebo in the parent study 659-102 and VX-659/TEZ/IVA in the current study 659-105) and the VX-659/TEZ/IVA - VX-659/TEZ/IVA category (participants who received VX-659/TEZ/IVA in the parent study 659-102 or/and VX-659/TEZ/IVA in the current study 659-105). Baseline was defined as the parent study baseline except for Placebo - VX-659/TEZ/IVA category, for which the baseline was defined as study 659-105 baseline.
From Baseline up to Week 96 (Study 659-105)
Number of Participants With at Least One PEx for Participants From the Parent Study 659-103
Time Frame: From Baseline up to Week 96 (Study 659-105)
PEx was defined as treatment with new or changed antibiotic therapy (intravenous, inhaled, or oral) for at least 4 sinopulmonary signs/symptoms. The time-to-first-PEx data were planned to be estimated using the KM method. However, because way less than 50% of participants had events, median time-to-first-event data were not estimable. Instead, the number of participants with at least one PEx event was assessed and reported for all participants from the parent study 659-103, that is combined for those in the TEZ/IVA - VX-659/TEZ/IVA category (participants who received TEZ/IVA in the parent study 659-103 and VX-659-TEZ/IVA in the current study 659-105) and the VX-659/TEZ/IVA - VX-659/TEZ/IVA category (participants who received VX-659/TEZ/IVA in the parent study 659-103 or/and in the current study 659-105).

The analysis was planned to be reported separately for TEZ/IVA - VX-659/TEZ/IVA category (participants who received TEZ/IVA in the parent study 659-103 and VX-659-TEZ/IVA in the current study 659-105) and VX-659/TEZ/IVA - VX-659/TEZ/IVA category (participants who received VX-659/TEZ/IVA in both the parent study 659-103 and in the current study 659-105) as pre-specified in analysis plan. Baseline was defined as the parent study baseline.

Absolute Change in Cystic Fibrosis Questionnaire-Revised (CFQ-R) Respiratory Domain Score for Participants From the Parent Study 659-102
Time Frame: From Baseline at Week 72 (Study 659-105)
The CFQ-R is a validated participant-reported outcome measuring health-related quality of life for participants with cystic fibrosis. Respiratory domain assessed respiratory symptoms, score range: 0-100; higher scores indicating fewer symptoms and better health-related quality of life. The analysis was planned to be reported separately for Placebo - VX-659/TEZ/IVA category (participants who received placebo in the parent study 659-102 and VX-659/TEZ/IVA in the current study 659-105) and VX-659/TEZ/IVA - VX-659/TEZ/IVA category (participants who received VX-659/TEZ/IVA in both the parent study 659-102 and in the current study 659-105) as pre-specified in analysis plan. Baseline was defined as the parent study baseline.
