A Direct Head-to-head Comparison of Ustekinumab with Infliximab for the Treatment of Ulcerative Colitis

Ustekinumab is a human monoclonal IgG1 antibody that blocks the p40 subunit of both IL-12 and IL-23 this antagonistic action inhibits the interaction of these cytokines with the IL-12Rβ1 receptor. The IL-12Rβ1 receptor is found on the surface of NK cells and T cells which reduces inflammation and alters the body's immune response

Infliximab is a biological therapy/immunotherapy medication designed to stimulate the body's immune system and treat certain diseases. Infliximab is a purified, recombinant DNA-derived chimeric IgG monoclonal antibody protein that contains both murine and human components that inhibit tumor necrosis factor-alpha (TNF-α). TNF-α is a signaling protein involved in acute phase reactions and systemic inflammation. Macrophages, CD4+ lymphocytes, NK cells, neutrophils, mast cells, eosinophils, and neurons produce TNF-α. This TNF-α inhibition inhibits the inflammatory reaction's cascade, leading to improved disease condition inflammatory bowel disease
