Statement of Need

Recently, interleukin (IL)-23 and the inflammatory IL-23/T-helper (Th)-17 axis have been identified as central drivers of inflammation related to inflammatory bowel disease (IBD). Science in the field of cytokine-targeting therapies, specifically in the field of IL-23 P19 targeting agents, is evolving rapidly, with the first approval in the class occurring in 2022 and several other agents in late-stage development. While all agents within the anti-IL-23 class will have the ability to bind to and neutralize IL-23 via binding to the P19 domain as an essential function, structural differences in the monoclonal antibody Fc fragment result in each agent having an overall unique clinical profile.

This CME Outfitters Webcast, entitled Clean-Up on IL-23: Integrating the Science of Inflammatory Targets into Treatment Decision-making in IBD, will feature an expert panel discussion on the science behind cytokine-targeting therapies and will utilize animated 3-D models to discuss therapeutic mechanisms of action (MOAs) of emerging agents, clinical distinctions between therapies, and individualizing treatments for lasting outcomes for patients with IBD.

Learning Objectives

  • Assess the role of various pro-inflammatory cytokines to inflammation in the pathogenesis of IBD
  • Classify the role of the IL-23 and Th17 pathway in IBD pathogenesis
  • Evaluate the potential clinical implications of CD64 receptor binding by anti-IL-23 mAbs in the treatment of IBD
