The purpose of this study is to evaluate the efficacy of vedolizumab when added to background aGvHD prophylaxis regimen compared to placebo and background aGvHD prophylaxis regimen on intestinal aGvHD-free survival by Day +180 in participants who receive allo-HSCT as treatment for a hematologic malignancy or myeloproliferative disorder.


The drug being tested in this study is called vedolizumab. Vedolizumab is being tested to treat people who are undergoing allo-HSCT transplantation. This study will look at the efficacy and safety of vedolizumab in the prophylaxis of intestinal aGvHD in participants undergoing allo-HSCT transplantation.

The study will enroll approximately 558 participants. Participants will be randomly assigned (by chance, like flipping a coin) in 1:1 ratio to one of the two treatment groups-which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need) along with background GvHD prophylaxis regimen:

  • Vedolizumab 300 mg
  • Placebo (dummy inactive intravenous infusion)

This multi-center trial will be conducted Worldwide. The overall time to participate in this study is 12 months.
