Dupilumab is a monoclonal antibody directed at the shared alpha subunit of interleukin-4 and −13 receptors, and is subsidised in Australia for severe uncontrolled asthma 1–4. Dupilumab inhibits eosinophil migration into tissues, but does not inhibit eosinophil production or release from bone marrow, resulting in a transient increase in circulating eosinophils 1. There have been reports of symptomatic dupilumab-associated hypereosinophilia 3, 5. Footnotes This manuscript has recently been accepted for publication in the ERJ Open Research.
