Vedolizumab Monotherapy Vs Combination Therapy With Tacrolimus in UC

Stopped early · Phase 3 · Has a placebo group

Conditions studied: Ulcerative Colitis

In brief

The aim of this study is to assess if a combination therapy of tacrolimus and vedolizumab is superior to vedolizumab monotherapy for induction of remission in moderate to severe UC, and its effect on long and short-term outcomes including colectomy rate. Secondary aim of this study is to assess the safety of tacrolimus as an induction agent in patients with UC.
