Study of VEGF-A Targeting NIR-II Fluorescence Endoscopy in the Gastrointestinal Tract
Recruiting now · Phase 1
Conditions studied: Gastrointestinal Carcinoma, Dysplasia, Gastrointestinal Polyp
In brief
In this study, the investigators are studying new ways to look for abnormal tissues of the gastrointestinal tract during an endoscopy. We are using a VEGF-A targeting fluorescent probe and a NIR-II fluorescent endoscope to help detect abnormal tissues that are hard to see by the naked eye. The main purposes of this study include: 1. To translate the NIR-II approach into the endoscopy, and understand its advantages and limitations on detecting abnormal tissues in gastrointestinal. 2. To validate whether topical administration of a targeting probe can stick to abnormal tissues and be detected by the NIR-II endoscope. 3. To validate the safety and effectiveness of the topical administration of VEGF-A targeting probes for clinical application.
