There are currently no approved therapies for chronic cough. Therapies that are currently on the market to treat cough have limited effectiveness and may have undesirable side effects.

The purpose of this study is to test the safety and effectiveness of a new therapy in patients who are experiencing an unexplained chronic cough.
