How WEZLANA Works

Wezlana is a monoclonal antibody that binds to the p40 protein subunit shared by the IL-12 and IL-23 cytokines. By targeting this subunit, the drug prevents these cytokines from interacting with the IL-12Rβ1 receptor on the surface of cells. This disruption inhibits signaling cascades that lead to natural killer cell activation and T-cell differentiation. This mechanism addresses the chronic inflammation that characterizes immune-mediated diseases like Crohn's disease and ulcerative colitis.
