An Open-Label, Phase 3 Study to Evaluate the Pharmacokinetics, Safety, and Immunogenicity of Vedolizumab Subcutaneous in Pediatric Subjects With Moderately to Severely Active Ulcerative Colitis or Crohn's Disease Who Achieved Clinical Response Following Open-Label Vedolizumab Intravenous Therapy
Takeda
Summary
The main aim of this study is to learn how the body of a child or teenager with moderately to severely active ulcerative colitis (UC) or Crohn's disease (CD) processes vedolizumab (pharmacokinetics) given just under the skin subcutaneously (SC). The participants will be treated with vedolizumab for up to 34 weeks. During the study, participants will visit their study clinic several times.
Description
The drug being tested in this study is vedolizumab. Vedolizumab is being tested to treat pediatric participants with moderate to severe active UC or CD who achieved clinical response following open-label vedolizumab intravenous (IV) therapy. The study will look at the pharmacokinetics, safety, and immunogenicity of vedolizumab. The study will enroll approximately 70 patients. During the Induction Period participants will receive 3 doses of vedolizumab IV infusion at Day 1, Week 2, and Week 6 based on their weight at Baseline as: * Participants ≥30 kilograms (kg), Vedolizumab (High Dose) * Pa…
