Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Safety and Tolerability as Assessed by Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)		From Baseline up to Week 100
Secondary	Absolute Change From Parent Study Baseline in Sweat Chloride (SwCl)	Sweat samples were collected using an approved collection device.	From Parent Study Baseline to Week 96
Secondary	Absolute Change From Parent Study Baseline in Lung Clearance Index 2.5 (LCI2.5)	The LCI2.5 index is the number of lung turnovers required to reduce the end tidal inert gas concentration to 1/40th of its starting values and is calculated by dividing the sum of exhaled tidal breaths (cumulative exhaled volume (CEV)) by simultaneously measured functional residual capacity (FRC). An LCI of 7.5 and below is normal; values greater than 7.5 are abnormal. LCI is able to detect abnormalities in lung function earlier than more traditional modalities such as spirometry.	From Parent Study Baseline to Week 96
