Primary Outcome Measures

Change from baseline in the 24-hour cough frequencyWeek 4

Assessed using an ambulatory cough monitor

Secondary Outcome Measures
NameTimeMethod
Change from Baseline in Leicester Cough Questionnaire (LCQ)Week 4

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 effect of cough on 3 main 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.
