What Is Calm2 Refractory Chronic Cough Study?

A persistent cough is more than an annoyance. It can seriously impact your quality of life and social interactions and may cause you to feel isolated or anxious. The Calm2 refractory chronic cough study aims to discover more about chronic cough and a potential new treatment option. This clinical research study is testing to see how safe an investigational drug is and whether it works in people with refractory chronic cough (RCC), including unexplained chronic cough. 

Participants will receive 1 of 2 doses of the active investigational drug and a placebo during the study. A placebo looks like the investigational drug but contains no active ingredients. The investigational drug and the placebo together may be referred to as the ‘study drug’. After the first part of the study, all participants will receive the investigational drug for 28 weeks. If you take part, you will be in the CALM-2 Study for about 1.5 years. You will visit the study centre at least 20 times and have  2 phone calls to check on your health.
