Eligibility
Key inclusion criteria
Main

Participants with moderately to severely active CD defined by a Pediatric Crohn's Disease Activity Index (PCDAI) >30 and an simple endoscopic score for Crohn's Disease (SES-CD) >6 (or an SES-CD =4 if disease is confined to terminal ileum) at screening endoscopy.
4. Participants who have failed, lost response to, or been intolerant to treatment with at least 1 of the following agents: corticosteroids, immunomodulators (eg, azathioprine (AZA), 6-mercaptopurine (6-MP), methotrexate [MTX]), and/or tumor necrosis factor (TNF)-a antagonist therapy (eg, infliximab, adalimumab). This includes participants who are dependent on corticosteroids or exclusive or partial enteral nutrition to control symptoms and who are experiencing worsening of disease in the moderate-to-severe range when attempting to wean off corticosteroids or discontinue exclusive enteral nutrition.
5. Participants with extensive colitis or pancolitis of >8 years' duration or left-sided colitis of >12 years' duration must have documented evidence of a negative surveillance colonoscopy within 12 months before screening.

Key exclusion criteria
1. Participants who have received either (1) an investigational biologic (other than those listed in Exclusion Criterion #1) within 60 days or 5 half-lives before screening (whichever is longer); or (2) an approved biologic or biosimilar agent within 2 weeks before the first dose of study drug or at any time during the screening period.
2. Participants with active cerebral/meningeal disease, signs/symptoms or history of progressive multifocal leukoencephalopathy (PML) or any other major neurological disorders including stroke, multiple sclerosis, brain tumor or neurodegenerative disease.

4. The participants has received any live vaccinations within 30 days prior to first dose.
5. Participants who currently require surgical intervention or are anticipated to require surgical intervention for CD during this study.

Summary
Brief summary
Vedolizumab is a medicine that helps to reduce inflammation and pain in the digestive system. In this study, children and teenagers with moderate to severe Crohn's disease will be treated with vedolizumab.

The main aim of the study is to check if participants achieve remission after treatment with the vedolizumab. Remission means symptoms improve or disappear and an endoscopy shows no signs of inflammation.

Participants will receive 3 infusions of vedolizumab over 6 weeks. Then, those who have a clinical response will receive either a high dose or low dose of vedolizumab once every 8 weeks. They will receive the same dose every time.
