Brief Summary:
The purpose of this study is to investigate the efficacy and safety of vedolizumab intravenous (IV) dose optimization on mucosal healing compared with the standard vedolizumab IV dosing regimen over a 30 week treatment period in subjects with moderately to severely active ulcerative colitis (UC) and high vedolizumab clearance, based on a Week 5 predefined serum vedolizumab concentration threshold less than (<) 50 microgram per milliliter (microg/mL) and who are Week 6 non-responders based on partial Mayo score.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Colitis, Ulcerative | Drug: Vedolizumab IV | Phase 4 |
The drug being tested in this study is called Vedolizumab. Vedolizumab will be administered as an IV infusion. It is being tested in this study with new doses. This study will investigate the efficacy and safety of dose optimization of vedolizumab IV, compared with standard dosing of vedolizumab IV, over a 30-week treatment period.
The study will enroll approximately 250 moderately to severely active subjects with UC in order to randomize approximately 100 non-responder subjects with high vedolizumab drug clearance. Subjects will receive induction therapy of vedolizumab IV 300 mg on Day 1 and Week 2 (Lead-in Period). At Week 5, serum vedolizumab concentration will be measured. At Week 6, subjects will be assessed for clinical response based on partial Mayo score.
Results of both Week 5 vedolizumab concentration and Week 6 clinical response will determine the treatment pathway. Those who are non-responders based on partial Mayo score at Week 6 and who are assessed as having high vedolizumab clearance, based on a predefined Week 5 serum vedolizumab concentration threshold (<50 microg/mL) will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups:
- Vedolizumab IV Standard Treatment
- Vedolizumab IV Dose Optimized
All randomized subjects will receive vedolizumab IV either 300 mg or 600 mg every 4 or 8 weeks.
This multi-center trial will be conducted in United States of America and Canada. The overall time to participate in this study is 56 weeks. Subjects will make multiple visits to the clinic, and will be contacted by telephone, 6 months after last dose of study drug for a long term follow-up safety survey.

Primary Outcome Measures :
- Percentage of Participants Achieving Mucosal Healing at Week 30 [ Time Frame: Week 30 ]Mucosal healing is defined as Mayo endoscopic subscore <=1 point. Mayo score was used in clinical trials to assess UC disease activity. It consisted of 4 disease activity variables (stool frequency, rectal bleeding, findings on sigmoidoscopy and physician's global assessment), each scored on a scale of 0 to 3, where 0 normal condition and 3 = severe disease condition. The total Mayo score ranges from 0 to 12, with higher scores indicating more severe disease.
Secondary Outcome Measures :
- Percentage of Participants Achieving Clinical Remission at Week 30 [ Time Frame: Week 30 ]Clinical remission is defined as a complete Mayo score of ≤2 points and no individual subscore >1 point at Week 30. Mayo score was used in clinical trials to assess UC disease activity. It consisted of 4 disease activity variables (stool frequency, rectal bleeding, findings on sigmoidoscopy and physician's global assessment), each scored on a scale of 0 to 3, where 0 = normal condition and 3 = severe disease condition. The total Mayo score ranges from 0 to 12, with higher scores indicating more severe disease.
- Percentage of Participants Achieving Clinical Response at Week 30 [ Time Frame: Week 30 ]Clinical response is defined as a reduction in complete Mayo score of ≥3 points and ≥30% from Baseline (Day 1) with an accompanying decrease in rectal bleeding subscore of ≥1 point or absolute rectal bleeding subscore of ≤1 point, at Week 30. Mayo score was used in clinical trials to assess UC disease activity. It consisted of 4 disease activity variables (stool frequency, rectal bleeding, findings on sigmoidoscopy and physician's global assessment), each scored on a scale of 0 to 3, where 0 = normal condition and 3 = severe disease condition. The total Mayo score ranges from 0 to 12, with higher scores indicating more severe disease.
- Percentage of Participants Achieving Clinical Response at Week 14 [ Time Frame: Week 14 ]Clinical response is defined as A reduction in partial Mayo score of ≥2 points and ≥25% from Baseline (Day 1) with an accompanying decrease in rectal bleeding subscore of ≥1 point or absolute rectal bleeding subscore of ≤1 point. Mayo score was used in clinical trials to assess UC disease activity. A composite index of 3 disease activity variables (stool frequency, rectal bleeding, and physician's global assessment), each scored on a scale from 0 to 3 with total partial Mayo score ranging from 0 to 9 (higher scores indicate greater disease activity). Partial Mayo score is calculated analogously to the complete Mayo score but excludes the sigmoidoscopy subscore.
- Percentage of Participants Achieving Corticosteroid-Free Remission [ Time Frame: Week 30 ]Participants using oral corticosteroids at Baseline who have discontinued corticosteroids and are in clinical remission. Mayo score was used in clinical trials to assess UC disease activity. Clinical Remission is defined as a complete Mayo score of <=2 points and no individual subscore >1 point at Week 30. It consisted of 4 disease activity variables (stool frequency, rectal bleeding, findings on sigmoidoscopy and physician's global assessment), each scored on a scale of 0 to 3, where 0 = normal condition and 3 = severe disease condition. The total Mayo score ranges from 0 to 12, with higher scores indicating more severe disease.
- Percentage of Participants Achieving Durable Clinical Response [ Time Frame: Weeks 14 and 30 ]A clinical response (based on partial Mayo score), which is defined as a reduction in partial Mayo score of ≥2 points and ≥25% from Baseline with an accompanying decrease in rectal bleeding subscore of ≥1 point or absolute rectal bleeding subscore of ≤1 point at Weeks 14 and 30. Mayo score was used in clinical trials to assess UC disease activity. A composite index of 3 disease activity variables (stool frequency, rectal bleeding, and physician's global assessment), each scored on a scale from 0 to 3 with total partial Mayo score ranging from 0 to 9 (higher scores indicate greater disease activity). Partial Mayo score is calculated analogously to the complete Mayo score but excludes the sigmoidoscopy subscore. Percentage of participants with durable clinical response, clinical response achieved at both Weeks 14 and 30 are reported.
