Active ingredients: Vedolizumab 300mg, per vial; lyophilized powder for intravenous (IV) infusion after reconstitution, preservative-free.
Indication: Moderately-to-severely active ulcerative colitis (UC): to induce and maintain clinical response and remission, to improve endoscopic mucosa appearance, and to achieve corticosteroid-free remission in adults who have had an inadequate or lost response with, or were intolerant to, a tumor necrosis factor (TNF) blocker or immunomodulator; or had an inadequate response with, were intolerant to, or were dependent on corticosteroids. Moderately-to-severely active Crohn disease (CD): to achieve clinical response and remission, and corticosteroid-free remission, in adults who have had an inadequate response with, or were intolerant to, a TNF blocker or immunomodulator or in adults who have had an inadequate response with, were intolerant to, or were dependent on corticosteroids.
Pharmacology: Vedolizumab is a humanized monoclonal antibody that specifically binds to the α4β7 integrin and blocks the interaction of α4β7 integrin with mucosal addressin cell adhesion molecule-1 (MAdCAM-1) and inhibits the migration of memory T-lymphocytes across the endothelium into inflamed gastrointestinal parenchymal tissue.
The interaction of the α4β7 integrin with MAdCAM-1 has been implicated as an important contributor to the chronic inflammation that is a hallmark of UC and CD.
Clinical trials: The safety and efficacy of Entyvio were evaluated in 2 randomized, double-blind, placebo-controlled trials in adults with moderately-to-severely active UC defined as Mayo score of 6 to 12 with endoscopy subscore of 2 or 3.
Results in these studies (UC Trials I and II) demonstrated that compared with patients treated with placebo, a greater percentage of patients treated with Entyvio achieved and maintained clinical response, achieved and maintained clinical remission, achieved corticosteroid-free clinical remission, and experienced improved endoscopic appearance of the mucosa at weeks 6 and 52.
Entyvio safety and efficacy were evaluated in 3 randomized, double-blind, placebo-controlled trials in adults with moderately-to-severely active CD (Crohn’s Disease Activity Index [CDAI] score of 220 to 450).
Results in CD Trial III showed that compared with persons treated with placebo, a greater percentage of patients treated with Entyvio achieved clinical response, clinical remission, and corticosteroid-free clinical remission at week 52.
