Recruitment Details

Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Participants took part in the study at 211 investigative sites worldwide. The Induction Phase contained 2 cohorts. The eligibility criteria for both cohorts were identical. The purpose of Cohort 2 was to provide enough responders to power the Maintenance Phase primary efficacy analysis.

Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
In Cohort 1, eligible patients who met entry criteria were randomized to treatment with double-blind vedolizumab 300 mg or placebo in a 3:2 ratio. All Cohort 2 patients were treated with open-label vedolizumab. In the Maintenance Phase participants were assigned to treatment groups based on their Induction Phase treatment and response to therapy.

Reporting Groups

	Description
Placebo	In the Induction Phase participants in Cohort 1 were randomized to receive double-blind placebo intravenous infusions at Week 0 and Week 2. Participants continued to receive placebo every 4 weeks from Week 6 through Week 50 during the Maintenance Phase, regardless of treatment response during induction.
Induction Phase: DB Vedolizumab	In the Induction Phase participants in Cohort 1 were randomized to receive double-blind (DB) vedolizumab 300 mg, administered by intravenous infusion at Week 0 and Week 2.
Induction Phase: OL Vedolizumab	In the Induction Phase participants in Cohort 2 received open-label (OL) vedolizumab 300 mg, administered by intravenous infusion at Week 0 and Week 2.
Maintenance Phase: Placebo	Participants who received vedolizumab during the Induction Phase and demonstrated a clinical response at Week 6 were then randomized to receive double-blind treatment with placebo every 4 weeks up to Week 50 during the Maintenance Phase.
Maintenance Phase: Vedolizumab Q8W	Participants who received vedolizumab during the Induction Phase and demonstrated a clinical response at Week 6 were then randomized to receive double-blind treatment with vedolizumab 300 mg every 8 weeks (Q8W) at Weeks 6, 14, 22, 30, 38, and 46, and, to maintain blinding, placebo infusions at Weeks 10, 18, 26, 34, 42, and 50.
Maintenance Phase: Vedolizumab Q4W	Participants who received vedolizumab during the Induction Phase and demonstrated a clinical response at Week 6 were then randomized to receive double-blind treatment with vedolizumab 300 mg every 4 weeks (Q4W) from Week 6 to Week 50.
Maintenance Phase: Non-responders	Participants who received vedolizumab during the Induction Phase who did not demonstrate a clinical response at Week 6 received open-label treatment with vedolizumab 300 mg every 4 weeks from Week 6 to Week 50.

[1]	Body weight data only available for 148 participants in the placebo arm.
[2]	BMI data only available for 148 participants in the placebo arm.
[3]	Duration of ulcerative colitis data only available for 519 participants in the Induction Phase: OL Vedolizumab arm.
[4]	The Mayo Score is a standard assessment tool to measure ulcerative colitis disease activity in clinical trials. The index consists of 4 components: two that are patient reported (rectal bleeding and stool frequency), a global assessment by the physician, and an endoscopic subscore. Each component is scored on a scale from 0 to 3 and the complete score ranges from 1 to 12 (higher scores indicate greater disease activity).
[5]	Number of participants for whom baseline fecal calprotectin data were available were 139, 213, and 505, respectively.
