ListOutcomeTime frameDescription
PrimaryAbsolute Change From Baseline in Percent Predicted Forced Expiratory Volume in 1 Second (FEV1) at Week 24Baseline, Week 16 and 24
Absolute change from baseline at week 24 was assessed as the average treatment effect at Week 16 and at Week 24. FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration. Hankinson and Wang standards were used to calculate percent predicted FEV1 (for age, gender, race, and height). The Hankinson standard was used for male participants 18 years and older and female participants 16 years and older. The Wang standard was used for male participants aged 12 to 17 years and for female participants aged 12 to 15 years.
SecondaryRelative Change From Baseline in Percent Predicted FEV1 at Week 24Baseline, Week 16 and 24Assessed as the average treatment effect at Week 16 and at Week 24. FEV1 and percent predicted FEV1 are defined in Outcome Measure (OM) 1.
SecondaryAbsolute Change From Baseline in Body Mass Index (BMI) at Week 24Baseline, Week 24BMI was defined as weight in kilogram (kg) divided by height\*height in square meter (m\^2).
SecondaryAbsolute Change From Baseline in Cystic Fibrosis Questionnaire-Revised (CFQ-R) Respiratory Domain Score at Week 24Baseline, Week 24
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 (for example, coughing, congestion, wheezing), the scaled score range: 0-100; higher scores indicating fewer symptoms and better health-related quality of life.
SecondaryPercentage of Participants With Response Based on Percent Predicted FEV1Week 16 and 24
A participant was considered as a responder if the participant had \>=5% increase from baseline in average percent predicted FEV1 at Week 16 and at Week 24 (relative change). FEV1 and percent predicted FEV1 are defined in OM 1. A participant with a missing average relative change from baseline in percent predicted FEV1 at Week 16 and at Week 24 was considered as a non-responder.
SecondaryNumber of Pulmonary Exacerbation Eventsthrough Week 24
The total number of days on study is equal to the Week 24 date or the last dose date (whichever occurred last) minus the first dose date plus 1. The total number of years (48 weeks) on study is equal to the number of days on study divided by 336. Pulmonary exacerbation events per year (48 weeks) are reported.
SecondaryAbsolute Change From Baseline in Weight at Week 24Baseline, Week 24
SecondaryAbsolute Change From Baseline in BMI-for-age Z-score at Week 24Baseline, Week 24
Z-Score is a statistical measure to evaluate how a single data point compares to a standard. It describes whether a mean was above or below the standard and how unusual the measurement is with range from -infinity to +infinity; 0: same mean, \>0: a greater mean, and \<0: a lesser mean than the standard. BMI-for-age z-score was calculated by using centers for disease control and prevention (CDC) growth charts for the pediatric population.
SecondaryTime-to-First Pulmonary Exacerbationthrough Week 24
Time to first pulmonary exacerbation was assessed using Cox Regression method. For participants who completed 24 weeks of treatment, participants without a pulmonary exacerbation before treatment completion were considered censored at the time of treatment completion or at the Week 24 Visit (whichever occurred last). For participants who prematurely discontinued study treatment, participants without a pulmonary exacerbation through the Week 24 Visit were considered censored at the time of the Week 24 Visit.
