Outcome Measures

Primary Outcomes (1)

  • Absolute Change in Percent Predicted Forced Expiratory Volume in 1 Second (ppFEV1)

    FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration.

    From Baseline at Week 12

Secondary Outcomes (3)

  • Absolute Change in Sweat Chloride (SwCl)

    From Baseline at Week 12

  • Observed Pre-Dose Concentration (Ctrough) of VX-561 and Its Metabolites (M1-VX-561 and M6-VX-561) and IVA and Its Metabolites (M1-IVA and M6-IVA)

    At Week 4

  • Safety and Tolerability as Assessed by Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)

    Baseline up to Week 16
