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.


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.

Mechanism of Action

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.


The intended route of administration is intravenous, therefore there is no absorption data and bioavailability is expected to be 100%.
Serum apparent volume of distribution at steady-state has been found to be moderately greater than the serum volume. It is therefore expected to be confined to the systemic circulation, as expected for a high molecular weight protein.
The expected consequence of metabolism is proteolytic degradation to small peptides and individual amino acids, and receptor-mediated clearance.


Vedolizumab has a low clearance of 0.180 to 0.266 ml/hr/kg.


Long-term studies in animals have not been performed to evaluate the carcinogenic potential, mutagenicity, or possible impairments to fertility. Elevated transaminase levels with or without elevated bilirubin has occurred in patients who have received this drug. Progressive multifocal leukoencephalopathy (PML) has not been reported with use of this drug, however it has occurred in patients who have received different integrin receptor antagonists and is therefore considered a risk for this product. Use of vedolizumab may increase risk of developing infections, and one study found that nasopharyngitis occurs more frequently with vedolizumab than with placebo for CD patients (Wang et al, 2014).
