About this study

Official title: An Open-Label, Phase 3 Study to Evaluate the Efficacy, Safety, and Pharmacokinetics of Intravenous (IV) Vedolizumab Administered Every 4 Weeks (Q4W) in Japanese Patients With Moderate to Severe Ulcerative Colitis or Crohn's Disease Who Experienced Secondary Loss of Response During Maintenance Therapy With Vedolizumab IV Administered Every 8 Weeks (Q8W)

The main aim of the study is to learn if 4-weekly vedolizumab improves symptoms of Japanese participants with moderate to severe ulcerative colitis (UC) or Crohn's disease (CD). Vedolizumab is commercially available in Japan for 8-weekly treatment but not for 4-weekly treatment.

The study doctors will also monitor side effects from the study treatment.

This study will take place in Japan.

At the first visit, the study doctor will check if each person can take part. For those who can take part, participants will receive vedolizumab intravenously once every 4 weeks. After 3 infusions of vedolizumab (which will be 12 weeks of treatment), the study doctor will assess if symptoms of the participants have improved.

Participants who do not have improved symptoms after 12 weeks of treatment with vedolizumab will stop this treatment. Then, they will visit the study clinic 16 weeks after their last infusion of vedolizumab for a final check-up.

Participants who have improved symptoms after 12 weeks of treatment with vedolizumab will continue to receive vedolizumab every 4 weeks. Then, after their last infusion of vedolizumab, the participants will visit the study clinic 16 weeks later for a final check-up. Finally, the study clinic will make a phone call to each participant 6 months after their last infusion to check if they have any health problems.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. UC Cohort: Percentage of Participants With Clinical Response at Week 12 Based on Modified Mayo Score

    Clinical response was defined as a reduction of greater than or equal to (>=) 2 points and >=25 percent (%) in modified mayo score, and a decrease of >=1 point in rectal bleeding sub-score or rectal bleeding sub-score of less than or equal to (<=) 1 from baseline (Week 0). Mayo score was an instrument designed to measure disease activity of UC. Modified mayo score consisted of 3 sub-scores: stool frequency, rectal bleeding, and mayo endoscopic sub-score (findings on endoscopy), each graded from 0 to 3 with higher scores indicating more severe disease. These scores were summed to give a total score range of 0 to 9. Here, a higher score indicated more severe disease.

    Measured: At Week 12

  2. CD Cohort: Percentage of Participants With Clinical Response at Week 12

    Clinical response was defined as a reduction of >=70 points in Crohn's Disease Activity Index (CDAI) score from baseline (Week 0). A CDAI was a multi-item instrument that measured severity of active Crohn's Disease monitored over 7 days included participant reported symptoms, physician-assessed signs, and laboratory markers. CDAI total score was equal to sum of weighted scores for subjective items (number of liquid/soft stools, degree of abdominal pain, general well-being); and objective items (use of anti-diarrhoeal medication, abdominal mass, haematocrit, presence of extraintestinal manifestation, body weight). CDAI scores ranged approximately from 0 to 600, higher scores indicated greater disease activity.

    Measured: At Week 12

Secondary outcomes (6)
  1. UC Cohort: Percentage of Participants With Clinical Remission at Week 12 Based on Modified Mayo Score

    Clinical remission was defined as a modified Mayo score of less than or equal to (<=) 2, and no individual sub-score greater than (>) 1. Mayo score was an instrument designed to measure disease activity of UC. Modified Mayo score consisted of 3 sub-scores: stool frequency, rectal bleeding, and Mayo endoscopic sub-score (findings on endoscopy), each graded from 0 to 3 with higher scores indicating more severe disease. These scores were summed to give a total score ranged of 0 to 9. Here, a higher score indicated a more severe disease.

    Measured: At Week 12

  2. UC Cohort: Percentage of Participants With Mucosal Healing at Week 12

    Mucosal healing was defined as a Mayo endoscopic sub-score of <=1, in participants with baseline Mayo endoscopic sub-score of >=2. Mayo score consisted of 4 sub-scores: stool frequency, rectal bleeding, mayo endoscopic sub-score (findings on endoscopy) and physician's global assessment, each graded from 0 to 3 with higher scores indicating more severe disease. These scores were summed to give a total score ranged of 0 to 12. Here, a higher score indicated a more severe disease.

    Measured: At Week 12

  3. UC Cohort: Percentage of Participants With Corticosteroid-Free Remission Based on Partial Mayo Score

    Corticosteroid-free remission was defined as participants using oral corticosteroids at baseline (Week 0) who have discontinued oral corticosteroids and were in clinical remission based on partial Mayo score at Week 52. Clinical remission based on partial Mayo score was defined as a partial Mayo score of =<2, and no individual sub-score >1. Mayo score was an instrument designed to measure disease activity of UC. Partial Mayo score consists of 3 sub-scores: stool frequency, rectal bleeding, and physician's global assessment, each graded from 0 to 3 with higher scores indicated more severe disease. These scores are summed to give a total score range of 0 to 9. Here, higher scores indicated more severe disease.

    Measured: At Week 52

  4. CD Cohort: Percentage of Participants With Clinical Remission at Week 12

    Clinical remission was defined as a CDAI score of <=150. A CDAI was a multi-item instrument that measured severity of active Crohn's Disease monitored over 7 days included participant reported symptoms, physician-assessed signs, and laboratory markers. CDAI total score was equal to sum of weighted scores for subjective items (number of liquid/soft stools, degree of abdominal pain, general well-being); and objective items (use of anti-diarrhoeal medication, abdominal mass, haematocrit, presence of extraintestinal manifestation, body weight). CDAI scores ranged approximately from 0 to 600, higher scores indicating greater disease activity.

    Measured: At Week 12

  5. CD Cohort: Percentage of Participants With Enhanced Clinical Response at Week 12

    Enhanced clinical response was defined as a reduction of >=100 points in CDAI score from baseline (Week 0). A CDAI was a multi-item instrument that measured severity of active Crohn's Disease monitored over 7 days included participant reported symptoms, physician-assessed signs, and laboratory markers. CDAI total score was equal to sum of weighted scores for subjective items (number of liquid/soft stools, degree of abdominal pain, general well-being); and objective items (use of anti-diarrhoeal medication, abdominal mass, haematocrit, presence of extraintestinal manifestation, body weight). CDAI scores ranged approximately from 0 to 600, higher scores indicating greater disease activity.

    Measured: At Week 12

  6. CD Cohort: Percentage of Participants With Corticosteroid-Free Remission

    Corticosteroid-free remission was defined as participants using oral corticosteroids at baseline (Week 0) who have discontinued oral corticosteroids and are in clinical remission at Week 52.

    Measured: At Week 52

A Phase 3 study testing Vedolizumab in people with Ulcerative Colitis and Crohn's Disease, run by Takeda at 20 sites in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 21 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 15 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 15 Jun 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

UC Cohort: Percentage of Participants With Clinical Response at Week 12 Based on Modified Mayo Score (time frame: At Week 12). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jun 2026.
