Prediction Tools for Vedolizumab Drug Exposure and Efficacy for Ulcerative Colitis and Crohn’s disease

Vedolizumab (VDZ) is an effective therapy for the management of patients with moderately to severely active ulcerative colitis (UC) or Crohn’s disease (CD) who have failed conventional therapy with aminosalicylates, corticosteroids, and thiopurines, as well as biologic therapy with tumor necrosis factor (TNF) antagonists. Several studies have identified potential predictors of treatment outcomes; however, the optimal approach to integrating predictors into routine practice is uncertain.No prior decision support tools exist to predict VDZ drug exposure in UC and CD and link this back to differences in effectiveness or response to VDZ dose escalation. By having a tool that can predict at baseline prior to start of therapy whether VDZ will be effective and what a patients drug exposure profile will be with VDZ, the provider can 1) determine if VDZ is an appropriate therapy to begin, 2) proactively monitor those patients deemed high risk for treatment failure with VDZ, and 3) proactively measure drug concentrations for VDZ to then increase the dose or the interval at which VDZ is administered to improve outcomes.
