RECRUITINGPhase 4INTERVENTIONAL

A Study of Vedolizumab Intravenous (IV) and Adalimumab or Vedolizumab and Ustekinumab in Adults With Crohn's Disease

An Open-Label, Phase 4 Study to Evaluate the Efficacy and Safety of Dual Targeted Therapy With Vedolizumab Intravenous (IV) and Adalimumab Subcutaneous (SC) or Vedolizumab IV and Ustekinumab IV/SC in Moderate to Severe Crohn's Disease (CD)

A Study of Vedolizumab Intravenous (IV) and Adalimumab or Vedolizumab and Ustekinumab in Adults With Crohn's Disease (NCT06045754) is a Phase 4 interventional studying Crohn's Disease, sponsored by Takeda. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

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.

What Stage of Research Is This?

Phase 4 studies happen after a treatment has been approved by the FDA. They monitor long-term safety, real-world effectiveness, and any rare side effects that only emerge in larger populations over longer periods. Phase 4 results sometimes lead to label changes, additional warnings, or — rarely — withdrawal of approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 100 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Crohn's Disease subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: Part A: 1. Has a confirmed diagnosis of CD at least 3 months before screening, based on endoscopy results. 2. Has moderately to severely active CD at Screening, defined as an SES-CD \>=6 (\>=4 if isolated ileal disease). 3. Has demonstrated at least 1 of the following (a, b, or c) to at least 1 IL antagonist or at least 1 tumor necrosis factor (TNF) antagonist, at doses approved for the treatment of CD: 1. Inadequate response after completing the full induction regimen; 2. Loss of response (recurrence of symptoms during scheduled maintenance dosing after prior clinical benefit); or 3. Intolerance (a significant adverse event that precluded further use, including but not limited to serious infection including opportunistic infections, malignancy, infusion-related and hypersensitivity reactions including anaphylaxis, and liver injury). Note: Participants with an inadequate response to \>2 classes of advanced therapies or \>1 agent in the same class are not eligible. Participants who discontinued a third class of advanced therapy for reasons other than inadequate response may be eligible after discussion with the Medical Monitor. Part B: 4. In the investigator's opinion, the participant exhibits a therapeutic benefit at Week 26. Who Should NOT Join This Trial: 1. CDAI score \> 450. 2. A current diagnosis of ulcerative colitis or indeterminate colitis. 3. Clinical evidence of an abdominal abscess. 4. Known fistula (other than perianal fistula) or phlegmon. 5. Known perianal fistula with abscess. 6. Ileostomy, colostomy, or severe, or symptomatic stenosis of the intestine. 7. Previous extensive bowel resection with 2 entire segments missing, of the following: terminal ileum, right colon, transverse colon, sigmoid and left colon, and rectum. 8. Short bowel syndrome. 9. Any planned surgical intervention for CD, except for seton placement for perianal fistula without abscess. ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening.
