Mepolizumab, sold under the brand name Nucala by GlaxoSmithKline, is a humanized monoclonal antibody used for the treatment of severe eosinophilic asthma, eosinophilic granulomatosis with polyangiitis, and hypereosinophilic syndrome (HES).[5] It recognizes and blocks interleukin-5 (IL-5), a signalling protein of the immune system.

The most common side effects include headache, injection site reactions, and back pain.[4]
