A Study to Identify Biomarkers of Intestinal Fibrosis in Small Bowel Crohn's Disease

Overview

About this study

The purpose of this study is to evaluate if specific blood, stool and MRI tests can tell the difference between bowel wall inflammation without scarring and bowel wall inflammation with scarring that can cause bowel blockages requiring surgery.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
