Percentage of Participants Who Achieve Complete Remission 12 Months After Initiation of Vedolizumab Therapy |
Complete remission will be measured by corticosteroid-free clinical, biochemical and transmural remission.Corticosteroid-free defined as no usage of any systemic or locally acting steroid.Corticosteroid-free clinical remission defined as Harvey Bradshaw Index (HBI) less than (<) 5 points and no concomitant corticosteroids.HBI score measures disease activity of CD. Clinical parameters:general well-being (0-4,higher score lower well being),abdominal pain(0-3,higher score more severe pain),number of liquid stools/day, abdominal mass (0-3),higher score presence of swelling in abdomen),complications (score 1/item).Total is sum of individual parameters.Score:minimum 0-no pre-specified maximum score,depends on number of liquid stools, higher scores indicating more severe disease.Biochemical remission defined as C-reactive protein(CRP) and fecal calprotectin (FCal) normalization.Transmural remission defined as bowel wall thickness(BWT) of <3 millimeter (mm) for all bowel segments upon IUS. |
Baseline up to 12 months |

Percentage of Participants Who Achieve Complete Remission |
Complete remission will be measured by corticosteroid-free clinical, biochemical and transmural remission. Corticosteroid-free defined as no usage of any systemic or locally acting steroid. Corticosteroid-free clinical remission defined as HBI <5 points and no concomitant corticosteroids. HBI score is used to measure disease activity of CD. Biochemical remission defined as CRP and FCal normalization. Transmural remission defined as BWT of <3 mm for all bowel segments upon Intestinal Ultrasonography (IUS). |

Percentage of Participants With Acceptance of IUS Monitoring and Assessment |
IUS is a 6 item questionnaire visual analogue scale (VAS). Out of 6 items, 2 items has score range 1 (completely unacceptable) to 10 (completely acceptable): Item 1-Acceptability as monitoring tool in IBD; and Item 2-Acceptability of other monitoring tools in IBD including 6 sub items with score range 1 to 10. Item 3- IUS examination leading to improvement of knowledge of their illness with score range 1 (totally useless) to 10 (very useful). Item 4: Tolerability of IUS with score range 1 (no discomfort) to 10 (much discomfort). Item 5: Choice of monitoring modality with score range 1 (most preferred) to 5 (least preferred). Item 6: IUS examination leading to improvement of knowledge/understanding of illness including 5 sub-items with score range of 1 (completely disagree) to 10 (strongly agree). Responses to these 6 questions will be summed to maximum score of 145. The total score range represents participant's experience of IUS and their acceptability to this assessment. |

Percentage of Participants With Improved Quality of Life Based on Health-related Quality of Life (HRQoL) as Measured by Short Inflammatory Bowel Disease Questionnaire (SIBDQ) |
The SIBDQ is an instrument used to assess quality of life and is a disease-specific HRQoL questionnaire, that consists of 10 questions grouped into four different dimensions: social, bowel, emotional, and systemic, each question is scored on a scale from 1 (a severe problem) to 7 (not a problem at all). The total score will be reported and will range from 10 to 70 with a higher score indicates a better health-related QoL. |
Baseline up to Month 18 |
