New treatment option for Moderately to Severely Active Crohn's Disease
Official title VECTORS - A Study to Evaluate Transmural Healing as a Treatment Target in Crohn's Disease
ClinicalTrials.gov ID: NCT06257706
What this study is testing
What is Vedolizumab?
Vedolizumab is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for moderately to severely active crohn's disease.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- 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.
- Phase 4: studies an already-approved treatment
- Time commitment: about 48 weeks

- Have a CD complication, such as symptomatic strictures in the small bowel with \>3 cm prestenotic dilatation on any imaging modality, requiring procedural intervention;
