Brief Summary
Transmural healing (TMH) is recognized as a potentially important measure of Crohn's disease (CD) activity but not a formal target. Observational studies suggest that TMH may be associated with better long-term outcomes. The study will evaluate TMH using noninvasive intestinal ultrasound (IUS), a patient-friendly technique that can be performed routinely in clinical practice. The aim of the study is to determine if treating to a target of corticosteroid-free (CS-free) IUS outcomes + clinical symptoms + biomarkers is superior to a target of clinical symptoms + biomarkers alone in achieving CS-free endoscopic remission measured by the Simple Endoscopic Score for Crohn's Disease (SES-CD). Qualified participants will be randomly assigned in a 1:1 ratio to one of 2 different target treatment groups. Group 1: Participants will be treated over 48 weeks to achieve a target of corticosteroid-free IUS-based outcomes + clinical remission + biomarker remission. At Week 22 and 30, the IUS-based component of the target will be IUS response and at Week 38, the final treatment target will be TMH. Group 2: Participants will be treated over 48 weeks to achieve a target of corticosteroid-free clinical remission + biomarker remission.
Eligibility Criteria
Inclusion Criteria: 1. Adults aged 18 to 80 years, inclusive, at the time of consent; 2. Moderately to severely active CD at baseline defined by a CDAI score of 220 to 450 inclusive and SES-CD, excluding the presence of narrowing component, ≥6 (or ≥4 for participants with isolated ileal disease); 3. BWT on IUS of \>4.0 mm in the terminal ileum or any colonic segment (excluding the rectum) as assessed by the mean of 2 longitudinal and 2 cross-sectional measurements of the same segment; 4. Biologic-naïve or have previous exposure (within the last 5 years of the screening date) to no more than 1 advanced therapeutic compound (approved biologic or small molecule drug) for the treatment of their CD. Note: only approximately 15% to 30% of the enrolled population will have had prior exposure to an advanced therapeutic; 5. Participants may continue stable dose (initiated at least 4 weeks prior to Screening) of 5-ASA for CD; 6. Persons of childbearing potential must have a negative serum pregnancy test prior to randomization and must use a highly effective method of contraception throughout the study. Females unable to bear children must have documentation of such in the source records; 7. Able to participate fully in all aspects of this clinical trial; 8. Written informed consent must be obtained and documented. Exclusion Criteria: 1. Current or previous treatment with vedolizumab, etrolizumab, or natalizumab; 2. Previously exposed to 2 or more compounds or classes of an advanced therapeutic compound (approved biologic or small molecule drug) for the treatment of their CD; 3. Change to oral corticosteroid therapy dosing within 2 weeks prior to randomization or a corticosteroid dose of \>40 mg of prednisone or equivalent at randomization; 4. Only have inflammation proximal to the terminal ileum that cannot be reached by ileocolonoscopy; 5. Have a CD complication, such as symptomatic strictures in the small bowel with \>3 cm prestenotic dilatation on any imaging modality, requiring procedural intervention; 6. Previous extensive colonic resection or missing \>2 segments out of 5 (terminal ileum, right colon, transverse colon, sigmoid and left colon, and rectum), ileorectal anastomosis, or a proctocolectomy; 7. Ostomy or ileoanal pouch; 8. Short bowel syndrome; 9. Fibrotic-only stricture in the ileum or colon without evidence of active inflammation (in the investigator's judgment), including any impassable stenosis; 10. Abscess \>2 cm, detected by IUS or endoscopy; participants with draining fistulas are not excluded; 11. Serious underlying disease other than CD that, in the opinion of the investigator, may interfere with the participant's ability to participate fully in the study or would compromise participant safety; 12. Positive stool test for Clostridioides difficile infection (as demonstrated by positive toxin); 13. Known HIV or hepatitis B or C infection. If a negative test result is available in the 12 months prior to randomization, retesting is not required; 14. Known active or latent tuberculosis (TB); if a negative test result is available in the 12 months prior to randomization, confirmatory testing (per standard of care) is not required before randomization; 15. Other systemic or opportunistic infection (including cytomegalovirus), any other clinically significant extraintestinal infection, or recurring infection within 6 months of randomization; 16. Has active cerebral/meningeal disease, signs, symptoms, or any history of progressive multifocal leukoencephalopathy (PML) prior to randomization; 17. Hypersensitivity, allergy, or intolerance to any excipient of vedolizumab or any other contraindication to vedolizumab; 18. Active severe infection such as sepsis, cytomegalovirus, listeriosis, or opportunistic infection. 19. Unwillingness to withhold protocol-prohibited medications during the trial; 20. Concurrent or previous participation in another clinical trial and received any investigational therapy within 30 days prior to randomization; 21. History of alcohol or drug abuse that in the opinion of the investigator may interfere with the participant's ability to comply with the study procedures; 22. Prior enrolment in the current study and had received study treatment; 23. Pregnant, lactating, or intending to become pregnant/impregnate a partner before, during, or within 18 weeks after the last dose; or intending to donate ova or sperm during such time period; 24. Vaccination with a live or live-attenuated vaccine within 4 weeks prior to randomization, or planned vaccination with a live or live-attenuated vaccine during participation in the study; 25. Any person performing mandatory military service, deprived of liberty, in a residential care setting, or any person who, due to a judicial decision, cannot take part in clinical studies; 26. The person is an immediate family member, study site employee, or is in a dependent relationship with a study site employee who is involved in conduct of this study (e.g., spouse, parent, child, sibling).
