LRG levels and IBD activity in European patients
Official title: Leucine-rich α2-glycoprotein Correlation With Clinical, Endoscopic and Histological Disease Activity of IBD in a EuRopean Context: LEADER Trial.
Run by Imelda GI Clinical Research Center · NCT07621783 · Data updated 2026-11-12
This study will test whether Leucine-rich α2-glycoprotein (LRG) levels reflect disease activity in adults with Crohn’s or ulcerative colitis who are undergoing routine endoscopy in Europe.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) with confirmed IBD (Crohn’s disease or ulcerative colitis) who are scheduled for endoscopy as part of routine care in Europe and who can provide informed consent.
✕Probably not a fit
Patients who do not have active disease or who do not have endoscopic assessment planned may see little, if any, diagnostic benefit from LRG testing in this study.

What this trial studies
This is an observational, prospective study focusing on adults with inflammatory bowel disease in Europe. Researchers will measure LRG and compare it to clinical assessments, endoscopic findings, and histology obtained as part of routine care. The aim is to see if LRG can serve as a biomarker that correlates with disease activity across Crohn’s disease and ulcerative colitis. Participation requires planned endoscopy and informed consent, with data collected during standard clinical workflows. No experimental interventions beyond measuring LRG are involved.
Why it matters
Potential benefit: If successful, LRG testing could help doctors gauge disease activity with a simple blood marker, potentially reducing the need for frequent invasive procedures.
How similar studies have gone: Previous research in IBD has explored biomarkers related to endoscopic activity, with mixed levels of success; this study adds European prospectively collected data on LRG correlations.
