Claudin-2 Immunostaining to Detect Active or Inactive Inflammation in IBD Biopsies
Official title: Histologic Healing in IBD: Comparison of "Standard" Scores With Expression of Claudin 2 and Impact on Outcomes
Run by IRCCS Policlinico S. Donato · NCT07710287 · Data updated 2026-11-12
This study tests whether staining for Claudin-2 in intestinal biopsy samples can help identify active vs. inactive inflammation in people with ulcerative colitis or Crohn's disease.

Is this trial a fit for you?
✓Likely a good fit
Adults with a confirmed diagnosis of ulcerative colitis or Crohn's disease undergoing biopsy for histologic evaluation.
✕Probably not a fit
Patients with non-IBD diagnoses or without histologic activity changes may not see a direct benefit.

What this trial studies
This observational study compares a new Claudin-2 immunostaining method with standard histologic scoring systems for inflammatory activity in IBD. Researchers will assess how well Claudin-2 staining agrees with established scores such as Geboes, Nancy, Robarts, PICASSO, and SHMHS. Participants will be followed for one year to correlate staining results with clinical outcomes, biomarkers, hospitalizations, surgeries, and treatment changes. Analyses will be conducted at the Promoter center's Biostatistics laboratory using demographic and histologic data. The goal is to determine feasibility, accuracy, and potential prognostic value of Claudin-2 staining in guiding disease management.
Why it matters
Potential benefit: If successful, Claudin-2 staining could provide a more consistent histologic assessment and help predict flares or need for therapy changes.
How similar studies have gone: Prior work in histologic markers has shown promise; this study tests a novel Claudin-2 approach in IBD.
