Study Endpoints
Primary Endpoints
Incidence of Respiratory Adverse Events of Special Interest (RAESIs)
Day 1 up to Day 84

RAESIs included chest discomfort, dyspnea (shortness of breath), respiration abnormal (chest tightness), asthma, bronchial hyperreactivity, bronchospasm, and wheezing.

Oro-caecal Transit Time
1 day of scanning

Time taken after eating for ingested food to be identifiable at the caecum on MRI

Absolute Change in Total Brody/CF-CT Score
From Baseline at Week 72

The exploratory Brody/CF-CT score semi-quantitatively scores the degree of structural lung disease as shown on CT in participants with CF. The score ranges from a minimum of 0 to a maximum of 219 with higher scores indicating more severe structural lung disease.

Absolute Change From Baseline in Mucociliary Clearance (MCC) at Day 28
Baseline, Day 28

MCC was assessed using an imaging technique that enables the tracking of mucus within the airways. MCC was expressed as the percentage of whole-lung clearance through 60 minutes at Baseline and Day 28.
