How NEMLUVIO Works

Nemolizumab-ilto is a humanized IgG2 monoclonal antibody that inhibits IL-31 signaling by binding selectively to the interleukin-31 receptor alpha (IL-31 RA). IL-31 is a naturally occurring cytokine involved in pruritus, inflammation, epidermal dysregulation, and fibrosis. By blocking this receptor, the drug inhibits IL-31-induced responses, including the release of proinflammatory cytokines and chemokines.
