About this study

Official title: A Prospective Follow-up Intervention Study: Detection of Early Esophageal Cancer by Near-infrared Fluoresence Molecular Endoscopy Using Bevacizumab-800CW

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. The phase I study, named VICE, completed within the UMCG, showed that synchronal use of VEGFA-guided near-infrared fluorescence molecular endoscopy (NIR-FME) and high-definition white light endoscopy (HD-WLE), following topical or systemic tracer administration, could be practiced to recognize dysplastic and early EAC lesions in patients with BE. Furthermore, early lesion detection was improved by ~33% using the topically applied tracer approach compared with HD-WL/NBI endoscopy. With this phase 2 intervention study the investigators aim to statistically confirm previous pilot (Phase I) clinical data showing that the combination of HD-WLE and FME using labelled bevacizumab improves early EC detection over the current clinical standard.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Bevacizumab-IRDye800CWDrug

    Topical administration of Bevacizumab-IRDye800CW during the endoscopic procedure.

  • Fluorescence endoscopyDiagnostic test

    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.

Topical administration of bevacizumab-800CWExperimentalThe tracer will be topically administered 5 minutes prior to the fluorescence endoscopy procedure (with the near infrared fluorescence endoscopy platform).
Receives: Drug: Bevacizumab-IRDye800CW; Diagnostic Test: Fluorescence endoscopy

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Fluorescence signal in patients with Barrett's Esophagus

    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.

    Measured: During the endoscopic procedure

Secondary outcomes (3)
  1. Ex vivo fluorescence singals

    Correlate and validate fluorescence signals detected in vivo with ex vivo histopathology grade of dysplasia and VEGF expression

    Measured: 2 years

  2. Number of participants with adverse events (AE), serious adverse events (SAE) and suspected unexpected serious adverse reactions (SUSAR).

    Data collection as a measure of safety and tolerability regarding administration of Bevacizumab-IRDye800CW

    Measured: Up to 1 week after administration of tracer

  3. Interrogate potential new EC biomarkers

    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.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Bevacizumab-IRDye800CW and Fluorescence endoscopy in people with Barrett Esophagus, run by University Medical Center Groningen at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 4 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact W.B. Nagengast, MD, PhD, PharmD (+31503612620, w.b.nagengast@umcg.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fluorescence signal in patients with Barrett's Esophagus (time frame: During the endoscopic procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03877601, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Nov 2020.
