Eosinophil-Driven Diseases (EDDs)

Our ambition to address unmet needs for people with EDDs

Our commitment to eosinophil-driven diseases

Building on a 50-year heritage in respiratory care and following the science of common pathways and underlying disease drivers from respiratory disease into immunology-driven disease areas, we’re continuing to better understand the important role of eosinophils as key effector cells in a range of potentially devasting inflammatory diseases, also known as eosinophil-driven diseases (EDDs).

EDDs are inflammatory illnesses in which elevated eosinophils are a direct cause or are thought to play a critical role.1 Some EDDs have limited or no approved treatment options, creating a significant unmet need for innovative medicines. We know now that a process called eosinophilic immune dysfunction may be responsible for the eosinophil recruitment and activation that is driving these diseases. Backed by a growing body of evidence, we’re committed to advancing the understanding of the role of eosinophils in inflammatory diseases across Respiratory & Immunology, with the aim to improve diagnosis, patient referrals and timely, appropriate treatment.


Patient Portraits

Types of eosinophil-driven diseases

We are currently investigating potential medicines to treat inflammatory, EDDs where unmet medical need remains significant and, in some cases, where we see an increasing prevalence.
