Eosinophil-Driven Diseases (EDDs)

Our ambition to address unmet needs for people with EDDs

Our commitment to eosinophil-driven diseases

We are committed to developing medicines for eosinophil-driven diseases (EDDs) where there is a clear unmet treatment need, with the ambition to improve the health outcomes and lives of millions of patients worldwide who face these debilitating, potentially fatal illnesses.1,2

EDDs are inflammatory illnesses in which elevated eosinophils are a direct cause or are thought to play a critical role.3 They include eosinophilic esophagitis, eosinophilic granulomatosis with polyangiitis, hypereosinophilic syndrome and some types of nasal polyposis, severe asthma and chronic obstructive pulmonary disease. 

Some EDDs have limited or no approved treatment options, creating a significant unmet need for innovative medicines.

Types of eosinophil-driven diseases
