Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the efficacy of ivacaftor in subjects with cystic fibrosis (CF) who have the R117H-CF transmembrane conductance regulator (CFTR) mutation;Secondary Objective: To evaluate the safety of ivacaftor in subjects with cystic fibrosis (CF) who have the R117H-CF transmembrane conductance regulator (CFTR) mutation;Primary end point(s): Absolute change from baseline in percent predicted forced expiratory volume in 1 second (FEV1);Timepoint(s) of evaluation of this end point: Through Week 24

Secondary

MeasureTime frame
Secondary end point(s): - Change from baseline in body mass index (BMI) - Change from baseline in sweat chloride - Change from baseline in the respiratory domain of the Cystic Fibrosis Questionnaire Revised (CFQ-R) - Time to first pulmonary exacerbation - Safety, as determined by adverse events, clinical laboratory values (serum chemistry, hematology, and coagulation), electrocardiograms (ECGs), ophthalmologic examinations, and vital signs;Timepoint(s) of evaluation of this end point: Through Week 24
