Change from baseline in untrimmed total mucus plugs score at TLC | ||||||||
End point description |
Mucus plugs was scored with a scoring system similar to that by Dunican et al. with the Severe Asthma Research Program (SARP) based on bronchopulmonary segmental (BS) anatomy. Mucus score was calculated by counting the number of BS which contained 1 or more mucus plug, up to a maximum score of 18 related to the 18 BS present. Here, a mucus plug is defined as complete occlusion of the airway visible at TLC. Each BS is given a score of 1 (mucus plug present) or 0 (mucus plug absent). The segment scores of each lobe are summed to generate a total mucus score for both lungs, where mucus score ranging from 0-18. Higher scores = worse outcome. Primary analysis population set consisted portion of evaluable population that did not have any acute asthma exacerbation nor lower respiratory tract infection during study period where evaluable population was defined as those who completed three doses of study intervention and had measurements of outcome at both baseline and Week 13.

Change from baseline in untrimmed total mucus plugs score at TLC with and without adjustment for pre-BD FEV1 | ||||||||||||
End point description |
Relationship between change from baseline (Week 0) in airway dynamics at Week 13, with and without adjustment for pre-BD FEV1 was assessed. Mucus plugs was scored with a scoring system based on BS anatomy. Mucus score was calculated by counting number of BS which contained 1 or more mucus plug, maximum score of 18 related to 18 BS present. Here, a mucus plug is defined as complete occlusion of the airway visible at TLC. Each BS is given a score of 1 (mucus plug present) or 0 (mucus plug absent). The segment scores of each lobe are summed to generate a total mucus score for both lungs, where mucus score ranging from 0-18. Higher scores=worse outcome. Primary analysis population set consisted portion of evaluable population that did not have any acute asthma exacerbation nor lower respiratory tract infection during study period where evaluable population was defined as those who completed three doses of study intervention and had measurements of outcome at both baseline and Week 13.

Change from baseline in untrimmed total air trapping at FRC with and without adjustment for pre-BD FEV1 | ||||||||||||
End point description |
The relationship between estimated average change from baseline (Week 0) in airway dynamics at Week 13, with and without accounting for baseline measurements of conventional lung function was assessed.
Primary analysis population set consisted portion of the evaluable population that did not have any acute asthma exacerbation nor lower respiratory tract infection during the study period where evaluable population was defined as those who completed the three doses of study intervention and had measurements of the outcome at both baseline and Week 13.

Change from baseline in untrimmed total mucus plugs score at TLC with and without adjustment for pre-BD FVC | ||||||||||||
End point description |
Relationship between change from baseline (Week 0) in airway dynamics at Week 13, with and without adjustment for pre-BD FVC was assessed. Mucus plugs was scored with a scoring system based on BS anatomy. Mucus score was calculated by counting the number of BS which contained 1 or more mucus plug, maximum score of 18 related to 18 BS present. Here, a mucus plug is defined as complete occlusion of the airway visible at TLC. Each BS is given a score of 1 (mucus plug present) or 0 (mucus plug absent). The segment scores of each lobe are summed to generate a total mucus score for both lungs, where mucus score ranging from 0-18. Higher scores=worse outcome. Primary analysis population set consisted portion of evaluable population that did not have any acute asthma exacerbation nor lower respiratory tract infection during study period where evaluable population= those who completed three doses of study intervention and had measurements of outcome at both baseline and Week 13.
