  • Title: Pharmacodynamic assessment of vedolizumab for the treatment of ulcerative colitis.
    Author: McLean LP, Cross RK.
    Journal: Expert Opin Drug Metab Toxicol; 2016 Jul; 12(7):833-42. PubMed ID: 27096357.
    Abstract:
    INTRODUCTION: Vedolizumab is an anti-integrin approved for the treatment of Crohn's disease and ulcerative colitis. By binding the α4β7-integrin heterodimer, vedolizumab blocks leukocyte translocation into gastrointestinal tissue. AREAS COVERED: This review discusses the chemistry, pharmacologic properties, clinical efficacy, and safety of vedolizumab in ulcerative colitis. Other medications available for the treatment of ulcerative colitis are also discussed. EXPERT OPINION: Vedolizumab is a promising new agent for the treatment of ulcerative colitis. Its mechanism of action differs from TNF-α inhibitors and immune suppressants, allowing it to be used in cases of TNF-α inhibitor failure or non-response, or as a first-line biologic drug. Available safety data suggests that vedolizumab is not associated with an increased risk of infection or malignancy; however, additional post-marketing data are required to confirm these initial reports. Vedolizumab is likely to be used in growing numbers of patients over the coming years.
