A Study of Vedolizumab Intravenous (IV) and Adalimumab or Vedolizumab and Ustekinumab in Adults With Crohn's Disease
brief summary
The main aim of this study is to learn about the effect of treatment with vedolizumab IV (vedolizumab) together with adalimumab or vedolizumab (VDZ) together with ustekinumab (UST) in adults with moderate to severe Crohn's Disease, and the effect of treatment with vedolizumab alone, after the dual targeted treatment. The study is conducted in two parts. In Part A, participants will receive the dual targeted treatment (vedolizumab together with either adalimumab or ustekinumab). In part B, participants will receive vedolizumab only. Part B will include participants who responded to the treatment in Part A. Each participant will be followed up for at least 26 weeks after the last dose of treatment.
detailed description
The drug being tested in this study is vedolizumab. Vedolizumab is being tested to treat people with moderate to severe Crohn's disease who have experienced inadequate response, loss of response or intolerance to either one prior interleukin \[IL\] antagonist, and no other biologic/small molecule (Group A); one IL antagonist and either one Janus kinase inhibitor (JAKi) or one TNFi (other than adalimumab) \[Group B\] (Cohort 1) or one prior tumor necrosis factor inhibitor \[TNFi\] and no other biologic/small molecule (Group C); one TNFi and either 1 JAKi or one IL antagonist (other than UST) (Group D) (Cohort 2). The study will look at the efficacy and safety of dual targeted therapy.
The study will enroll approximately 100 participants. Participants will be assigned to one of the two treatment groups in Part A:
* Part A, Cohort 1: Vedolizumab + Adalimumab * Part A, Cohort 2: Vedolizumab + Ustekinumab
All participants who achieve therapeutic benefit in Part A will receive vedolizumab IV 300 mg monotherapy from Week 30 until Week 46 in Part B. Participants will be followed for a further 20-week safety follow-up period to Week 72 (or 26 weeks post-last dose of study drug).
This multi-center trial will be conducted in the United States and Canada. The overall time to participate in this study is approximately 76 weeks.
