Blood and stool tests could revolutionize IBD monitoring

NCT ID NCT07686406

First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time

Summary

This observational study is collecting blood, stool, and tissue samples from 6,000 people with inflammatory bowel disease (Crohn's disease or ulcerative colitis), along with their relatives and healthy volunteers. Researchers aim to identify biomarkers that can assess intestinal inflammation, monitor how well routine treatments are working, and predict disease progression. The goal is to develop simple tests that could replace or reduce the need for invasive procedures like colonoscopies.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If successful, this could lead to better ways to monitor Crohn's disease and ulcerative colitis, helping doctors predict flare-ups and tailor treatments to each patient.
What could go wrong
This is an observational study, not a treatment trial. It may take years to validate any biomarkers, and the findings might not lead to immediate changes in patient care.
