Shorter Disease Duration is Associated With Higher Rates of Response to Vedolizumab in Patients With Crohn’s Disease but Not Ulcerative Colitis

Patients with Crohn's disease (CD), but not ulcerative colitis (UC), of shorter duration have higher rates of response to tumor necrosis factor (TNF) antagonists than patients with longer disease duration. Little is known about the association between disease duration and response to other biologic agents. We aimed to evaluate response of patients with CD or UC to vedolizumab, stratified by disease duration.
