Abstract
Seasonal allergic rhinitis (SAR) is a chronic inflammatory condition primarily mediated by type 2 immune responses, typically triggered by specific pollens. Stapokibart is a humanized monoclonal antibody anti-interleukin-4 receptor α subunit, thereby blocking IL-4 and IL-13 signaling pathways. Clinical studies of stapokibart in healthy adults and SAR patients revealed a favorable safety profile and significant clinical efficacy. Stapokibart has been approved for treating adults with atopic dermatitis, chronic rhinosinusitis with nasal polyposis, and SAR in China. This article reviews the mechanism of action, pharmacology, and available clinical trial data regarding the efficacy and safety of stapokibart in SAR.
