A Study of Vedolizumab in Children and Teenagers With Moderate to Severe Crohn's Disease (CD)
What this study is about
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.
View original scientific description
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.

Primary outcome measures
Percentage of Participants With Clinical Remission at Week 54 Based on Pediatric Crohn's Disease Activity Index (PCDAI) Score ≤10
Time frame: Week 54
Clinical remission is defined by PCDAI score ≤10. The PCDAI was specifically designed for use in children. The PCDAI includes a child-specific item: the height velocity variable as well as three laboratory parameters: hematocrit (HCT) (adjusted for age and sex), erythrocyte sedimentation rate (ESR), and albumin level. The PCDAI score ranges from 0 to 100, with higher scores indicating more active disease. A score of \<10 will be consistent with inactive disease, 11 to 30 will indicate mild disease, and \>30 will indicate moderate to severe disease. A decrease of 12.5 points is taken as evidence of improvement.
Percentage of Participants With Endoscopic Response at Week 54 Based on Simple Endoscopic Score for Crohn's Disease [SES-CD] Score
Time frame: Week 54
Endoscopic response is defined as at least a 50% reduction in SES-CD score from Baseline. The overall SES-CD score ranges from 0 to 56 and is the sum of 4 variables (ie, size of ulcers \[cm\], ulcerated surface, affected surface \[%\], and presence of narrowing) across 5 bowel segments (ie, rectum, descending and sigmoid colon, transverse colon, ascending colon, and ileum). 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 segmental SES-CD score is the sum of the 4 variables for each bowel segment and can range from 0 to 12, where each individual variable score ranges from 0 to 3.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- The participants has moderately to severely active CD, unresponsive or intolerant to their current standard of care (SOC). 2. The participants weigh ≥10 kg at the time of screening and enrollment into the study. 3. Participants with Crohn's disease (CD) diagnosed at least 1 month before screening. 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)-α antagonist therapy (eg, infliximab, adalimumab). This includes participants who are dependent on corticosteroids or exclusive or partial en

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
