Pharmacology
Vedolizumab is a humanized IgG1 monoclonal antibody that specifically binds to the alpha4beta7 integrin and blocks its interaction with mucosal addressin cell adhesion molecule-1 (MAdCAM-1), inhibiting the migration of memory T-lymphocytes into inflamed gastrointestinal tissue; the mechanism is gut-selective and does not affect the alpha4beta1 or alphaEbeta7 integrins or VCAM-1 interactions.
Prednisone is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties that suppresses inflammatory processes (edema, capillary dilatation, leukocyte migration), modifies immune responses, and produces metabolic effects including promotion of gluconeogenesis, protein catabolism, and altered calcium and electrolyte balance.
