Primary Outcome(s)

Main Objective: To evaluate the efficacy of lumacaftor in combination with ivacaftor at
Week 24 in subjects with cystic fibrosis (CF) who are homozygous for
the F508del mutation on the CF transmembrane conductance regulator
(CFTR) gene

Timepoint(s) of evaluation of this end point: Week 24

Primary end point(s): Absolute change in percent predicted forced expiratory volume in 1 second (FEV1) from baseline at Week 24

Secondary Objective: To evaluate the safety of lumacaftor in combination with ivacaftor through Week 24

To investigate the pharmacokinetics (PK) of lumacaftor and its metabolite, M28 (M28 lumacaftor) and ivacaftor and its metabolites M1 and M6 (M1 ivacaftor and M6 ivacaftor)

Secondary Outcome(s)

Timepoint(s) of evaluation of this end point: Weeks 24 and 28

Secondary end point(s): Relative change in percent predicted forced expiratory volume in 1 second (FEV1) from baseline at Week 24

Absolute change in body mass index (BMI) from baseline at Week 24

Number of pulmonary exacerbations from baseline through Week 24

Absolute change in Cystic Fibrosis Questionnaire – Revised (CFQ-R) respiratory domain score from baseline at Week 24

Safety and tolerability assessments based on adverse events (AEs), clinical laboratory values (hematology, serum chemistry, coagulation studies, and urinalysis), standard digital electrocardiograms (ECGs), pulse oximetry and vital signs
