ListOutcomeTime frameDescription
PrimaryTreatment Period: Safety and Tolerability as Assessed by Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)From Day 1 up to Week 196
SecondaryAbsolute Change in Percent Predicted Forced Expiratory Volume in 1 Second (ppFEV1) for 102/105 Efficacy SetFrom Baseline at Week 192
FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration. This analysis set included study 102 parent study participants who received Placebo-ELX/TEZ/IVA and ELX/TEZ/IVA-ELX/TEZ/IVA.
SecondaryAbsolute Change in Percent Predicted Forced Expiratory Volume in 1 Second (ppFEV1) for 103/105 Efficacy SetFrom Baseline at Week 192
FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration. This analysis set included study 103 parent study participants who received TEZ/IVA-ELX/TEZ/IVA and ELX/TEZ/IVA-ELX/TEZ/IVA.
SecondaryAbsolute Change in Sweat Chloride (SwCl) for 102/105 Efficacy SetFrom Baseline at Week 192Sweat samples were collected using an approved collection device. This analysis set included study 102 parent study participants who received Placebo-ELX/TEZ/IVA and ELX/TEZ/IVA-ELX/TEZ/IVA.
SecondaryAbsolute Change in Sweat Chloride (SwCl) for 103/105 Efficacy SetFrom Baseline at Week 192Sweat samples were collected using an approved collection device. This analysis set included study 103 parent study participants who received TEZ/IVA-ELX/TEZ/IVA and ELX/TEZ/IVA-ELX/TEZ/IVA.
SecondaryNumber of Pulmonary Exacerbations (PEx) for 102/105 Efficacy SetFrom Baseline at Week 192Pulmonary exacerbation was defined as the treatment with new or changed antibiotic therapy (intravenous, inhaled, or oral) for greater than or equal to 4 sinopulmonary signs/symptoms.
SecondaryNumber of Pulmonary Exacerbations (PEx) for 103/105 Efficacy SetFrom Baseline at Week 192Pulmonary exacerbation was defined as the treatment with new or changed antibiotic therapy (intravenous, inhaled, or oral) for greater than or equal to 4 sinopulmonary signs/symptoms.
SecondaryTime to First PEx for 102/105 Efficacy SetFrom Baseline at Week 192
Time-to-first pulmonary exacerbation was analyzed using Kaplan-Meier estimates and expressed in terms of event-free probability. PEx was defined as the treatment with new or changed antibiotic therapy (intravenous, inhaled, or oral) for greater than or equal to 4 sinopulmonary signs/symptoms.
SecondaryTime to First PEx for 103/105 Efficacy SetFrom Baseline at Week 192
Time-to-first pulmonary exacerbation was analyzed using Kaplan-Meier estimates and expressed in terms of event-free probability. PEx was defined as the treatment with new or changed antibiotic therapy (intravenous, inhaled, or oral) for greater than or equal to 4 sinopulmonary signs/symptoms.
SecondaryAbsolute Change in Body Mass Index (BMI) for 102/105 Efficacy SetFrom Baseline at Week 192
BMI was defined as weight in kilogram (kg) divided by height in square meter (m\^2).This analysis set included study 102 parent study participants who received Placebo-ELX/TEZ/IVA and ELX/TEZ/IVA-ELX/TEZ/IVA.
SecondaryAbsolute Change in Body Mass Index (BMI) for 103/105 Efficacy SetFrom Baseline at Week 192
BMI was defined as weight in kilogram (kg) divided by height in square meter (m\^2).This analysis set included study 103 parent study participants who received TEZ/IVA-ELX/TEZ/IVA and ELX/TEZ/IVA-ELX/TEZ/IVA.
SecondaryAbsolute Change in BMI Z-score for 102/105 Efficacy SetFrom Baseline at Week 192
BMI was defined as weight in kg divided by height in m\^2. Z-score is a statistical measure to describe whether a mean was above or below the standard. BMI, adjusted for age and sex, was analyzed as BMI-for-age z-score. A z-score of 0 is equal to the mean and is considered normal. Lower numbers indicate values lower than the mean and higher numbers indicate values higher than the mean. Higher values are indicative of higher BMI. This analysis set included study 102 parent study participants who received Placebo-ELX/TEZ/IVA and ELX/TEZ/IVA-ELX/TEZ/IVA.

BMI, adjusted for age and sex, was analyzed as BMI-for-age z-score. A z-score of 0 is equal to the mean and is considered normal.

This analysis set included study 103 parent study participants who received TEZ/IVA-ELX/TEZ/IVA and ELX/TEZ/IVA-ELX/TEZ/IVA.
SecondaryAbsolute Change in Body Weight for 102/105 Efficacy SetFrom Baseline at Week 192This analysis set included study 102 parent study participants who received Placebo-ELX/TEZ/IVA and ELX/TEZ/IVA-ELX/TEZ/IVA.
SecondaryAbsolute Change in Body Weight for 103/105 Efficacy SetFrom Baseline at Week 192This analysis set included study 103 parent study participants who received TEZ/IVA and ELX/TEZ/IVA.
SecondaryAbsolute Change From Baseline in Cystic Fibrosis Questionnaire-Revised (CFQ-R) Respiratory Domain Score for 102/105 Efficacy SetFrom Baseline at Week 192
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. This analysis set included study 102 parent study participants who received Placebo-ELX/TEZ/IVA and ELX/TEZ/IVA-ELX/TEZ/IVA.
