Summary
This is a randomized, double-blind, placebo-controlled, crossover, single center study of SCH
619734 in subjects with chronic cough from an unknown cause. Subjects will be randomized to
receive SCH 619734 or placebo for 7 days with 7 days' follow-up. After a 6 week washout
period, subjects will be crossed over to the other treatment. The primary objective is to
evaluate the effectiveness of SCH 619734 in reducing cough reflex sensitivity as determined
by a challenge with capsaicin, an agent that induces cough.
