Imaging intestinal fibrosis in patients with inflammatory bowel disease

FAPi-PET Imaging of in Vivo Fibrosis in Inflammatory Bowel Disease Patients

Phase 2 Interventional Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) · NCT06604260

This study is testing a new imaging technique to see if it can help find intestinal scarring in people with inflammatory bowel disease like Crohn's disease and ulcerative colitis.

What this trial studies

This study evaluates the feasibility of using 68Ga-FAPi PET/CT imaging to detect intestinal fibrosis in patients diagnosed with inflammatory bowel disease (IBD), specifically Crohn's disease and ulcerative colitis. The research aims to correlate the uptake of 68Ga-FAPi with fibroblast activation protein (FAP) expression in intestinal biopsies and resection specimens. By assessing these relationships, the study seeks to improve diagnostic capabilities for fibrosis in IBD patients.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with a confirmed diagnosis of Crohn's disease or ulcerative colitis who exhibit active disease symptoms.

Not a fit: Patients who are pregnant or have undergone IBD-related surgeries within the last five years may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic methods for detecting fibrosis in IBD, potentially guiding more effective treatment strategies.

How similar studies have performed: While the use of PET imaging in IBD is an emerging field, this specific approach using 68Ga-FAPi PET/CT for fibrosis detection is relatively novel and has not been extensively tested in prior studies.
