Experimental: Topical administration of bevacizumab-800CW
The tracer will be topically administered 5 minutes prior to the fluorescence endoscopy procedure (with the near infrared fluorescence endoscopy platform).
Topical administration of Bevacizumab-IRDye800CW during the endoscopic procedure.
Diagnostic Test: Fluorescence endoscopy
Device: Molecular Fluorescence Endoscopy platform A flexible fluorescence fiber-bundle is attached to a fluorescence camera platform to enable the detection of fluorescence signals. The fluorescence fiber-probe is inserted through the standard working channel of the standard clinical endoscope.
- Fluorescence signal in patients with Barrett's Esophagus [ Time Frame: During the endoscopic procedure ]Evaluating the performance of FME with topical administration of Bevacizumab-800CW for detection of neoplasia in BE patients compared to HD-WLE to make an estimation of the diagnostic accuracy in terms of sensitivity and specificity in order to make a power size calculation for the Phase III trial.
- Ex vivo fluorescence singals [ Time Frame: 2 years ]Correlate and validate fluorescence signals detected in vivo with ex vivo histopathology grade of dysplasia and VEGF expression
- Number of participants with adverse events (AE), serious adverse events (SAE) and suspected unexpected serious adverse reactions (SUSAR). [ Time Frame: Up to 1 week after administration of tracer ]Data collection as a measure of safety and tolerability regarding administration of Bevacizumab-IRDye800CW
- Interrogate potential new EC biomarkers [ Time Frame: 2 years ]We will perform ex-vivo binding experiments with tracers against GREM1, -SULF1 and -PRKCi on the fresh EMR if available and compare them against the in-vivo WLE/NIR-FME findings. We will analyze the sensitivity and specificity of the novel markers alone or in combination. The targeting moieties will be coupled with different fluorophores allowing for multi-parametric analysis.
