About this study

Official title: Determining the Safety and Feasibility of Optical Coherence Tomography and Near Infrared Fluorescence: a Prospective Pilot Intervention Study

To improve detection of premalignant lesions in the gastrointestinal tract (the rectum and the esophagus) there is a need for better endoscopic visualization and the ability for targeted biopsies. The University Medical Center Groningen (UMCG) developed a fluorescent tracer by labelling the VEGF-A-targeting humanized monoclonal antibody bevacizumab, currently used in anti-cancer therapy, with the fluorescent dye bevacizumab-800CW (IRDye800CW). In several phase I studies and phase II studies, either completed or currently running, in the UMCG, the use of VEGF-A-guided near-infrared (NIR) fluorescence molecular endoscopy (FME) in combination with high-definition white light endoscopy (HD-WLE) shows an improved detection rate of early premalignant lesions. In this study the safety and feasibility of a next generation imaging system will be tested. This system uses immune optical coherence tomography (immuno-OCT) and near infrared fluorescence (NIRF) with the targeted tracer (Bevacizumab-800CW) for improvement of the detection of dysplastic lesions in Barret's esophagus (BE) and colorectal polyp detection. The system provides more depth information and can eventually be used without the guidance of the regular endoscopy system.

What is being measured

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

  1. Number of Adverse Device-related Events (ADEs) and Serious Adverse Device-related Events (SADEs) using immuno-OCT

    Any events related to the device.

    Measured: during procedure

Secondary outcomes (4)
  1. Validation of the immuno-OCT system: FME

    Validation of the immuno-OCT endoscopy results compared to fluorescence seen in FME imaging results.

    Measured: During procedure

  2. Validation of OCT system: Ex vivo fluorescence imaging

    Validation of the immuno-OCT endoscopy results compared to the correlation of ex vivo fluorescent signals to histopathological analysis results.

    Measured: During procedure

  3. validation of OCT system: ex vivo immuno-OCT imaging

    Validation of the immuno-OCT endoscopy results compared to the correlation of in vivo and ex vivo immuno-OCT imaging to histopathological analysis results.

    Measured: During procedure

  4. validation of OCT system: immunohistochemistry

    Validation of the in vivo immune-OCT endoscopy results by comparing it to histopathological analysis results.

    Measured: Once, as soon as possible after procedure

Questions about this trial

What is this clinical trial studying?

A study testing Bevacizumab-800CW in people with Colon Carcinoma and Barrett Esophagus, run by University Medical Center Groningen.

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 8 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 20 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

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.

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?

Number of Adverse Device-related Events (ADEs) and Serious Adverse Device-related Events (SADEs) using immuno-OCT (time frame: during procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 20 Mar 2024.
