Fluorescent Probe VGT-309 to ID Cancerous Colorectal Lesions During Augmented Colonoscopy

The purpose of this study is to determine the safety and feasibility of VGT-309 for the visualization of colorectal tumors in real-time using near-infrared (NIR) fluorescence endoscopy. In addition, signatures of 50+ biomarkers will be evaluated in biopsies using CODEX multi-plexing.
