Trial Title: Oral Bevacizumab-800CW and Cetuximab-800CW Administration to Detect Early Esophageal Adenocarcinomas

NCT ID: NCT05745857

Condition: Barrett's Esophagus Without Dysplasia
Barrett Oesophagitis With Dysplasia
Esophageal Adenocarcinoma

Conditions: Official terms:
Adenocarcinoma
Barrett Esophagus
Esophageal Neoplasms
Esophagitis
Bevacizumab
Cetuximab

Conditions: Keywords:
Fluorescence molecular endoscopy
Spectroscopy
Barrett's esophagus
Esophageal adenocarcinoma

Study type: Interventional

Study phase: Phase 2

Overall status: Not yet recruiting

Study design:

Allocation: Non-Randomized

Intervention model: Factorial Assignment

Intervention model description: Arm 1: Oral bevacizumab-800CW If oral administration is feasible the investigators will move on to arm 2, if it does not seem feasible the investigators will move on to arm 3. Arm 2: Oral cetuximab-800CW The investigators will move on to combined oral bevacizumab-800CW/cetuximab-800CW if oral cetuximab-800CW seems feasible. If it does not seem feasible, they will administer oral bevacizumab-800CW to a control group of non-dysplastic Barrett's esophagus patients. Arm 3 (only performed if oral administration does not work) Topical administration of bevacizumab-800CW compared to combined topical administration of bevacizumab-800CW/cetuximab-800CW. This group will be expanded if combined administration increases lesion detection. If this is not the case, the investigators will include a control group of non-dysplastic patients with Barrett's esophagus as a control group who will receive topical bevacizumab-800CW.

Summary: Previous studies have confirmed the great potential of quantitative fluorescence molecular endoscopy (qFME) when looking at additional lesion detection initially missed by high-definition white light endoscopy (HD-WLE) for surveillance of Barrett's esophagus.

Detailed description: However, the investigators hypothesized, that additional lesions can potentially be identified by simultaneous use of two targeted tracers because of variable expression of vascular endothelial growth factor A (VEGFA) and epidermal growth factor receptor (EGFR )within oesophageal adenocarcinoma (EAC). Until now, solely intravenous and topical administration of the tracers has been investigated. However, optimization of tracer administration and shortened incubation is necessary for clinical translation and implementation of this new technique from Barrett's esophagus (BE) expert centers to regional non-expert centers. BE surveillance procedures normally takes up to 15 minutes at regional hospitals, of which most of the procedural time is needed to take biopsies according to the Seattle protocol. Introducing qFME into these hospitals would elongate the procedure time with at least 10 - 15 minutes. This would increase healthcare costs and put increased pressure on BE healthcare. Ideally, the gastroenterologist can immediately start with the qFME procedure without any incubation time while maintaining the best target-to-background ratios (TBR) possible. Oral administration by drinking the tracer prior to the procedure would eliminate incubation time and its consequences. Quantified qFME with oral tracer administration and targeted biopsies could potentially replace the time-consuming, high miss rate Seattle protocol, improve lesion detection and decrease global healthcare costs associated with BE.
