Primary Outcome Measures:
  • Rate of change in lung function, as measured by change in FEV1 [ Time Frame: 160 Weeks ]

Secondary Outcome Measures:
  • Change in absolute FEV1 from baseline [ Time Frame: Weeks 12, 24, 36, 48, 72, 96, 120, 144, and 160 ]
  • Change in FEV1 percent predicted value from baseline [ Time Frame: Weeks 12, 24, 36, 48, 72, 96, 120, 144, and 160 ]
  • Change in FEF25%-75% and forced vital capacity (FVC) from baseline [ Time Frame: Weeks 12, 24, 36, 48, 72, 96, 120, 144, and 160 ]
  • Incidence of pulmonary exacerbations [ Time Frame: 160 Weeks ]
  • Changes in Pseudomonas aeruginosa status [ Time Frame: 160 Weeks ]
  • Number of days of intravenous (IV) antibiotic use for a respiratory complaint [ Time Frame: 160 Weeks ]
  • Incidence of hospitalizations/Emergency room (ER) visits for a respiratory complaint [ Time Frame: 160 Weeks ]
  • Number of days hospitalized for a respiratory complaint [ Time Frame: 160 Weeks ]
  • Incidence of treatment emergent adverse events (AEs), serious adverse events (SAEs) and withdrawals due to AEs [ Time Frame: 160 Weeks ]
  • Incidence of patients with significant decrease in absolute FEV1 at any visit from baseline [ Time Frame: 160 Weeks ]
  • Changes in physical exam findings including height, weight, and body mass index from baseline [ Time Frame: Weeks 48, 96, and 160 ]
  • Changes in hematology, serum chemistry, and urinalysis parameters from baseline [ Time Frame: Weeks 24, 48, 72, 96, 120, 144, and 160 ]
  • Incidence of hospitalizations/ER visits [ Time Frame: 160 Weeks ]
  • Incidence of early discontinuations from the study [ Time Frame: 160 Weeks ]
