A Study of Vedolizumab Intravenous (IV) and Adalimumab or Vedolizumab and Ustekinumab in Adults With Crohn's Disease
Study Details
Study Description
Brief Summary
The main aim of this study is to learn about the effect of treatment with vedolizumab IV (vedolizumab) together with adalimumab or vedolizumab together with ustekinumab in adults with moderate to severe Crohn's Disease, and the effect of treatment with vedolizumab alone, after the dual targeted treatment.
The study is conducted in two parts. In Part A, participants will receive the dual targeted treatment (vedolizumab together with either adalimumab or ustekinumab). In part B, participants will receive vedolizumab only. Part B will include participants who responded to the treatment in Part A.
Each participant will be followed up for at least 26 weeks after the last dose of treatment.

| Phase 4 |
Detailed Description
The drug being tested in this study is vedolizumab. Vedolizumab is being tested to treat people with moderate to severe Crohn's disease who have experienced inadequate response, loss of response or intolerance to either one prior interleukin [IL] antagonist (Cohort 1) or one prior tumor necrosis factor inhibitor [TNFi] (Cohort 2). The study will look at the efficacy and safety of dual targeted therapy.
The study will enroll approximately 150 patients. Participants will be assigned to one of the two treatment groups in Part A:
-
Part A, Cohort 1: Vedolizumab + Adalimumab
-
Part A, Cohort 2: Vedolizumab + Ustekinumab
All participants who achieve clinical remission in Part A will receive vedolizumab IV 300 mg monotherapy from Week 30 until Week 46 in Part B. Participants will be followed for a further 20-week safety follow-up period to Week 72 (or 26 weeks post-last dose of study drug).
This multi-center trial will be conducted in the United States and Canada. The overall time to participate in this study is approximately 76 weeks.

Outcome Measures
Primary Outcome Measures
- Part A: Percentage of Participants Achieving Clinical Remission Based on the Crohn's Disease Activity Index (CDAI) at Week 26 [Week 26]
Clinical remission is defined as a CDAI score of ≤150 points. CDAI assesses CD based on clinical signs such as number of liquid or very soft stools, abdominal pain, general wellbeing, extra-intestinal manifestations of CD, antidiarrheal use, presence of abdominal mass, hematocrit and body weight. CDAI consists of eight factors, each summed after adjustment with a weighting factor. Total score ranges from 0 to 600 points. Higher scores indicate more severity.
- Part B: Percentage of Participants in Clinical Remission Based on the CDAI at Week 52 [Week 52]
Clinical remission is defined as a CDAI score of ≤150 points. CDAI assesses CD based on clinical signs such as number of liquid or very soft stools, abdominal pain, general wellbeing, extra-intestinal manifestations of CD, antidiarrheal use, presence of abdominal mass, hematocrit and body weight. CDAI consists of eight factors, each summed after adjustment with a weighting factor. Total score ranges from 0 to 600 points. Higher scores indicate more severity.
Secondary Outcome Measures
- Percentage of Participants Achieving Clinical Remission Based on the CDAI at Week 12 [Week 12]
Clinical remission is defined as a CDAI score of ≤150 points. CDAI assesses CD based on clinical signs such as number of liquid or very soft stools, abdominal pain, general wellbeing, extra-intestinal manifestations of CD, antidiarrheal use, presence of abdominal mass, hematocrit and body weight. CDAI consists of eight factors, each summed after adjustment with a weighting factor. Total score ranges from 0 to 600 points. Higher scores indicate more severity.
- Percentage of Participants Achieving 2-item Patient-reported Outcome Measure (PRO2) Remission at Weeks 12, 26, and 52 [Weeks 12, 26 and 52]
Clinical remission based on PRO2 is defined as PRO2 score ≤8 from baseline. The PRO2 is comprised of the stool frequency and abdominal pain components of the CDAI. The PRO-2 score is the sum of the abdominal pain and stool frequency subscores of the CDAI score. The average daily number of liquid or very soft stools and abdominal pain score (with 0 indicating no pain and 3 indicating severe pain) are weighted according to the CDAI multiplication factors (2 for stool frequency and 5 for abdominal pain). A higher score indicates more frequent stools and more severe abdominal pain.
- Change in PRO2 Score from Week 26 to 52 [Weeks 26 and 52]
The PRO2 is comprised of the stool frequency and abdominal pain components of the CDAI. The PRO-2 score is the sum of the abdominal pain and stool frequency subscores of the CDAI score. The average daily number of liquid or very soft stools and abdominal pain score (with 0 indicating no pain and 3 indicating severe pain) are weighted according to the CDAI multiplication factors (2 for stool frequency and 5 for abdominal pain). A higher score indicates more frequent stools and more severe abdominal pain.
- Percentage of Participants with Stool Frequency Remission at Weeks 12, 26, and 52 [Weeks 12, 26, and 52]
Stool frequency remission is defined as average daily number of liquid or very soft stools ≤3 and not worse than baseline assessed as per the stool frequency subscore of the CDAI score. The average daily number is weighted according to the CDAI multiplication factor of 2 for stool frequency. A higher score indicates more frequent stools.
- Percentage of Participants with Abdominal Pain Remission at Weeks 12, 26, and 52 [Weeks 12, 26, and 52]
Abdominal pain remission is defined as abdominal pain score ≤1, and not worse than baseline assessed as per the abdominal pain subscore of the CDAI score. The abdominal pain score (with 0 indicating no pain and 3 indicating severe pain) is weighted according to the CDAI multiplication factor of 5. A higher score indicates more severe abdominal pain.
- Percentage of Participants Achieving Endoscopic Remission Based on Simple Endoscopic Score for Crohn's Disease (SES-CD) at Weeks 26 and 52 [Weeks 26 and 52]
Endoscopic remission as per SES-CD is defined as SES-CD score from 0-2. SES-CD evaluates 4 endoscopic variables (ulcer size, percentage of surface area (SA) that is ulcerated, percentage of SA affected, and presence and type of narrowings in 5 colonic segments evaluated during ileocolonoscopy. Each variable is coded from 0 to 3 based on severity, where 0 is none or not severe and 3 is most severe case, with sum of scores for each variable ranging from 0 to 15, except for presence of narrowing. Presence of narrowing ranges from 0 to 11 since a severity of 3 represents a narrowing which a colonoscope cannot be passed and, thus, can only be observed once among the bowel segments. The overall SES-CD score ranges from 0 to 56 and is sum of 4 variables across 5 bowel segments. Higher scores indicate more severe disease. Percentage of participants achieving endoscopic remission based on SES-CD at either Week 26 or Week 52 will be reported in this outcome measure.

Each variable is coded from 0 to 3 based on severity, where 0 is none or not severe and 3 is most severe case, with sum of scores for each variable ranging from 0 to 15, except for presence of narrowing. Presence of narrowing ranges from 0 to 11 since a severity of 3 represents a narrowing which a colonoscope cannot be passed and, thus, can only be observed once among the bowel segments. The overall SES-CD score ranges from 0 to 56 and is sum of 4 variables across 5 bowel segments. Higher scores indicate more severe disease.

Each variable is coded from 0 to 3 based on severity, where 0 is none or not severe and 3 is the most severe case, with the sum of the scores for each variable ranging from 0 to 15, except for presence of narrowing. Presence of narrowing ranges from 0 to 11 since a severity of 3 represents a narrowing which a colonoscope cannot be passed and, thus, can only be observed once among the bowel segments. The overall SES-CD score ranges from 0 to 56 and is the sum of 4 variables across 5 bowel segments. Higher scores indicate more severe disease.
