Primary Outcome Measures:
  • Safety and tolerability assessments based on adverse events, clinical laboratory values (hematology and serum chemistry), and standard 12 lead electrocardiograms (ECGs) [ Time Frame: Baseline up to 28 days after the last dose (up to Week 28) ]

Secondary Outcome Measures:
  • Absolute change from baseline in percent predicted forced expiratory volume in 1 second (ppFEV1) at each visit up to Week 24 [ Time Frame: From Baseline, up to Week 24 ]
  • Absolute change from baseline in FEV1 (in Liters [L]) at each visit up to week 24 [ Time Frame: From Baseline, up to Week 24 ]
  • Total number of days participants received intravenous (IV) antibiotics for pulmonary exacerbations [ Time Frame: Baseline through Week 24 ]
  • Number of hospitalizations (all causes) participants had [ Time Frame: Baseline through Week 24 ]
  • Absolute change from baseline to average of Day 15 and Week 4 measurements in sweat chloride [ Time Frame: Baseline, Day 15 and Week 4 ]
  • Absolute change from baseline in Cystic Fibrosis Questionnaire - Revised (CFQ-R) respiratory domain score through Week 24 [ Time Frame: Baseline, through Week 24 ]
