The US Food and Drug Administration has approved a new indication for Dupixent (dupilumab), broadening its role as a leading anti-inflammatory medicine for allergic diseases. The new use is for eosinophilic oesophagitis (EoE), a chronic inflammatory disorder in which eosinophils, a type of white blood cell, are found in the tissue of the oesophagus. This can impair a person’s ability to swallow. Dupixent is a monoclonal antibody that blocks interleukin 4 and interleukin 13 – part of the inflammatory pathway.
