Clinical Trial Summary

To improve detection of esophageal (pre)malignant lesions during surveillance endoscopy of patients at risk of developing malignancies, for example in Barrett's Esophagus (BE), there is a need for better endoscopic visualization and the ability for targeted biopsies. Optical molecular imaging of neoplasia associated biomarkers could form a promising technique to accommodate this need. It is known that the biomarker Vascular Endothelial Growth Factor (VEGF) is overexpressed in dysplastic and neoplastic areas in BE segments versus normal tissue and has proven to be a valid target for molecular imaging. The University Medical Center Groningen (UMCG) developed a fluorescent tracer by labeling the VEGF-targeting humanized monoclonal antibody bevacizumab, currently used in anti-cancer therapy, with the fluorescent dye IRDye800CW. We hypothesize that when bevacizumab-IRDye800CW is administered, it accumulates in VEGF expressing high grade dysplasia (HGD) and esophageal adenocarcinoma (EAC), enabling early cancer visualization using a newly developed fluorescent NIR fiber-bundle. This hypothesis will be tested in this pilot intervention study.
