Study Endpoints

Primary Endpoints

Change from baseline in cough reflex sensitivity as assessed by log10 C5 resulting from a capsaicin challenge. A capsaicin challenge will be performed on the first day (before dosing) and on the last day of each 2 week treatment period.
After 2 weeks of treatment.

Secondary Endpoints

Change from baseline in hourly cough rate over 24 hours (using an automated cough counter). Baseline will be measured as the total no. of coughs on Day 1 of each treatment period and compared with the same value on the last day of each treatment period.
After 2 weeks of treatment.
