Guselkumab in Inflammatory Bowel Disease: Mechanism, Clinical Efficacy, Safety, and Treatment Positioning. (PubMed, J Clin Med) - Sep 16, 2026 - "Guselkumab is a monoclonal antibody directed against the p19 subunit of interleukin-23 (IL-23), thereby preventing IL-23 binding to the IL-23 receptor. In registrational trials, there were significant improvements across multiple clinical and endoscopic endpoints in comparison to ustekinumab, although these trials were not powered for formal superiority testing. This narrative review summarises the biological rationale for IL-23 blockade, reviews the available clinical evidence, discusses practical considerations for its use, and considers its place in the landscape of IBD treatments."
