Real‐world multicentre observational study including population pharmacokinetic modelling to evaluate the exposure–response relationship of vedolizumab in inflammatory bowel disease: ERELATE Study

In this real-world study, a positive exposure-response relationship was observed for vedolizumab. Vedolizumab concentration during induction may be an important predictor of short- and long-term outcomes, and similarly, vedolizumab baseline clearance may be an important predictor of remission.
