Siltuximab is a monoclonal antibody that binds the cytokine interleukin-6 (IL-6). This prevents IL-6 from binding to both soluble and membrane-bound IL-6 receptors. IL-6 is involved in diverse physiological processes, including coordination of the immune response to infection. When IL-6 is overproduced by cells within the lymph nodes it contributes to overgrowth of lymphatic cells and other systemic symptoms.
