| DrugBank Description: | Vedolizumab is a recombinant humanized IgG1 monoclonal antibody directed against the human lymphocyte α4β7 integrin, a key mediator of gastrointestinal inflammation. It is used in the treatment of moderate to severe active ulcerative colitis and Crohn's disease for patients who have had an inadequate response with, lost response to, or were intolerant to inhibitors of tumor necrosis factor-alpha (TNF-alpha) or other conventional therapies. By blocking its primary target, α4β7 integrin, vedolizumab reduces inflammation in the gut. Vedolizumab is administered by IV infusion over a period of 30 minutes; after the first dose, it is given again at two and six weeks and then every 8 weeks thereafter. |

| DrugBank Indication: | Vedolizumab is indicated for adult patients with moderately to severely active UC or CD who have had an inadequate response with, lost response to, or were intolerant to a tumor necrosis factor (TNF) blocker or immunomodulator; or had an inadequate response with, were intolerant to, or demonstrated dependence on corticosteroids. |
| DrugBank Pharmacology: | Non-clinical studies have shown that the pharmacodynamic effects of vedolizumab are reversible upon removal of the antibody: pharmacologic activity of cells inhibited by vedolizumab could be partially restored within 24 hours after removal, with near complete restoration within 4 days. There are no known drug interactions as vedolizumab is a humanized antibody and does not modulate production of cytokines, which is known to affect drug metabolism. |
| DrugBank MoA: | Vedolizumab binds to α4β7 integrin, a key mediator of gastrointestinal inflammation expressed on the surfaces of T and B lymphocytes. By selectively inhibiting the α4β7 integrin, vedolizumab inhibits adhesion of lymphocytes to its natural ligand, mucosal addressin cell adhesion molecule-1 (MAdCAM-1), thereby preventing lymphocytic cells from entering the gut lamina propria and gut-associated lymphoid tissue (GALT). Specifically inhibiting this pathway alleviates GI inflammation without impairing systemic immune responses. |
| Targets: | Integrin alpha-4 antibody; Integrin beta-7 antibody |
