Secondary Outcome Measures
NameTimeMethod
Change from Baseline in Cough Severity Visual Analogue Scale at Week 24Baseline, Week 24

Assessed by Cough Severity Visual Analogue Scale \[VAS\] by the participant on a 100 mm visual analog scale where higher scores indicate greater severity.

Percentage of Participants With ≥ 30mm Reduction, ≥ 20mm Reduction From Baseline in Cough Severity Visual Analog Scale (VAS) at Week 24Baseline, Week 24

Assessed by Cough Severity Visual Analogue Scale \[VAS\] by the participant on a 100 mm visual analog scale where higher scores indicate greater severity.

Percentage of Participants With ≥30%, ≥50%, and ≥70% Reduction From Baseline in 24-Hour Cough Frequency at Week 24Baseline, Week 24

Assessed using an ambulatory cough monitor

Change from Baseline in the Leicester Cough Questionnaire (LCQ) Total Score at Week 24Baseline, Week 24

The LCQ is a patient-reported quality of life (QOL) measure of chronic cough. The questionnaire consists of 19 items to which the patient responds on a 7-point Likert response scale (from 1 to 7). Each item assesses symptoms during cough and the impact of cough on 3 domains: physical, psychological, and social. Domain scores range from 1-7, and the total score ranges from 3 - 21; a higher score indicates a better quality of life.

Percentage of Participants With a ≥1.3-point Increase From Baseline in Leicester Cough Questionnaire (LCQ) Total Score at Week 24Baseline, Week 24

The LCQ is a patient-reported quality of life (QOL) measure of chronic cough. The questionnaire consists of 19 items to which the patient responds on a 7-point Likert response scale (from 1 to 7). Each item assesses symptoms during cough and the impact of cough on 3 domains: physical, psychological, and social. Domain scores range from 1-7, and the total score ranges from 3 - 21; a higher score indicates a better quality of life.
