About BELLUS Health (www.bellushealth.com)

BELLUS Health is a clinical-stage biopharmaceutical company developing novel therapeutics for the treatment of RCC and other hypersensitization-related disorders. The Company's product candidate, BLU-5937, is being developed for the treatment of RCC and chronic pruritus associated with AD.

RCC is a cough lasting more than 8 weeks despite appropriate treatment for underlying condition(s). It is estimated that there are approximately 9 million patients in the United States suffering from RCC. RCC is associated with significant adverse physical, social, and psychosocial effects on health and quality of life. Currently, there is no specific therapy approved for RCC and current treatment options are limited.

Chronic pruritus associated with AD is an irritating sensation that leads to scratching and persists for longer than 6 weeks in AD patients. It is estimated that up to 10% of adults in the United States suffer from AD – almost all report symptoms of pruritus with over 50% of patients attributing chronic pruritus as their most burdensome symptom. Despite currently available treatments targeting AD, there continues to be a lack of options targeting the burden of pruritus in patients with AD.
