About Bellus Health Inc.

Bellus Health is a clinical-stage biopharmaceutical company developing novel therapeutics for the treatment of RCC and other hypersensitivity indications. The company has successfully completed a phase 2b trial in RCC and has initiated the CALM phase 3 clinical program (CALM-1 and CALM-2).

Chronic cough is a cough lasting longer than eight weeks. When the cause of chronic cough cannot be identified or the cough persists despite treatment of all identified associated causes, the condition is referred to as RCC. It is estimated that there are approximately nine million patients in the United States suffering from RCC. RCC is associated with significant adverse physical, social and psychological effects on health and quality of life. Currently, there is no specific therapy approved for RCC outside of Japan and Switzerland and treatment options are limited.
