Vedolizumab IV in Pediatric Participants With Ulcerative Colitis or Crohn's Disease
The purpose of this study is to evaluate vedolizumab pharmacokinetics (PK), safety and tolerability in pediatric participants with moderately to severely active ulcerative colitis or Crohn's disease.
A Phase 2, Randomized, Double-Blind, Dose-Ranging Study to Determine the Pharmacokinetics, Safety and Tolerability of Vedolizumab IV in Pediatric Subjects With Ulcerative Colitis or Crohn's Disease
The drug being tested in this study is called vedolizumab. Vedolizumab is being tested to treat pediatric participants who have moderately to severely active ulcerative colitis (UC) or Crohn's disease (CD). This study will look at the pharmacokinetics (PK), efficacy, immunogenicity, safety, and tolerability in participants who take vedolizumab.
The study will enroll approximately 80 patients. Participants will be randomly assigned (by chance, like flipping a coin) to one of the two dose regimens (high or low) per weight group in ratio 1:1—which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need):
- Vedolizumab high dose group - Vedolizumab 300 mg or 200 mg
- Vedolizumab low dose group - Vedolizumab 150 mg or 100 mg
All participants will be administered vedolizumab via intravenous (IV) infusion. Participants assigned to the low dose group who do not achieve clinical response (based on pediatric ulcerative colitis/Crohn's disease activity index) at Week 14 will receive the high dose (ie, 300 mg for participants ≥30 kg baseline weight and 200 mg for participants <30 kg baseline weight) of vedolizumab IV at Week 14.
This multi-center trial will be conducted worldwide. The overall time to participate in this study is up to 36 weeks. After completing the Week 22 Visit procedures, eligible participants may enter an extension study. Participants will make multiple visits to the clinic, and those who do not enter extension study will have a final visit 18 weeks after last dose of study drug for a follow-up assessment. Participants who do not enter the extension study will also participate in a long-term safety follow-up, by telephone, 6 months after the last dose of study drug.
