Trial summary

Subjects enrolled in this study will have biopsies obtained and sent to Dr. Fitzgerald's lab for analysis of a validated biomarker panel. Subjects will be stratified to either high or low risk of progression to esophageal adenocarcinoma (EAC) based on biomarker panel results. Read more about this study

Who may be able to join

  • Able to read, comprehend, and complete the consent form.
  • Aged 18 to 80.
  • Diagnosed with at least 3 centimeters (>3cm) of Barrett's Esophagus (BE) AND no dysplasia or low grade dysplasia per review by pathologist.

Who cannot join

  • Pregnant women.
  • Current use of blood thinners such as coumadin, warfarin, heparin and/or low molecular weight heparin (requires discontinuation of medication 5 days prior to and 6 days after EGD).

About this study

Subjects enrolled in this study will have biopsies obtained and sent to Dr. Fitzgerald's lab for analysis of a validated biomarker panel. Subjects will be stratified to either high or low risk of progression to esophageal adenocarcinoma (EAC) based on biomarker panel results. Biomarker panel results will not be communicated to sites. Subjects with low grade dysplasia will be offered the option of treatment (radiofrequency ablation (RFA)) as part of routine care. Subjects with low grade dysplasia who do not want RFA and subjects with no dysplasia will receive surveillance endoscopy in 1 year per routine care. All subjects will be administered a questionnaire seeking information about hypothetical willingness to be randomized to treatment or surveillance.

Read the detailed description

The Investigators have previously completed a validation study in which they have identified a panel of biomarkers that can predict progression of subjects with BE and no dysplasia or low-grade dysplasia to esophageal adenocarcinoma (EAC). The biomarker panel, performed by the Fitzgerald lab, included ploidy (by image cytometry), AOL (histochemistry (IHC)), p53 (IHC), cyclin A (IHC), and dysplasia. These markers have been validated and demonstrated to be highly predictive of both progression to EAC, as well as the presence of occult malignancy elsewhere in the specimen (field effect). The final panel of validated biomarkers will be used in this study to identify patients at high risk of developing EAC.

The study will recruit 100 patients across 4 sites (University of North Carolina, Case Western Reserve University, University of Cambridge, and Academic Medical Center in Amsterdam). The specific aims of this pilot study are to:

  1. Demonstrate that the international, multicenter team can work together,
  2. Define the logistics of assaying biomarkers in real time such that in the future interventional trial, results could influence clinical decision-making, and,
  3. Provide further data to inform a power calculation for the full trial.

Subjects enrolled in the study will complete a questionnaire gathering hypothetical willingness to be randomized to receive endoscopic treatment intervention (RFA) or surveillance endoscopy.

Biopsy samples will be obtained from all subjects and tested for all biomarkers in the panel. Results of the biomarker panel will not be communicated to sites. Subjects with low grade dysplasia will be offered the option of receiving radiofrequency ablation (RFA) as part of routine care. Subjects with low grade dysplasia who agree to RFA will receive RFA as part of routine care. Subjects with no dysplasia and subjects with low grade dysplasia who do not want to receive RFA will receive a surveillance endoscopy in 1 year as part of routine care.

The goals of this pilot study are to ascertain the proportion of subjects in the high risk arm, to demonstrate the plausibility of performing the biomarker analysis efficiently in a sizable group of patients, to demonstrate the feasibility of delivering the endoscopic intervention (RFA), to obtain 1 year pilot data regarding progression in the high risk arm for use in sample size calculations, and to document collaboration among the centers.

What participants receive

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

Study groups in NCT02075905
Study groupRoleWhat they receive
Barrett's Esophagus-Low Grade DysplasiaSubjects enrolled who have Barrett's Esophagus with low grade dysplasia. No research intervention is administered.
Barrett's Esophagus-no dysplasiaSubjects enrolled with Barrett's Esophagus and no dysplasia. No research intervention is administered.

What is being measured

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

  1. Risk Stratification

    This is a pilot study the main objective of which is to determine feasibility and preparation for a larger scale study. Baseline tissue samples will be used to stratify subjects as either high or low risk of progression to esophageal adenocarcinoma (EAC) based on biomarker panel results. Biomarker panel risk stratification will be compared to data collected 1 year post enrollment regarding current pathology and ablation treatments received since enrollment.

Questions about this trial

What is this clinical trial studying?

An observational study of Barrett's Esophagus and Esophageal Adenocarcinoma, run by University of North Carolina, Chapel Hill at 4 sites in 3 countries.

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 6 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: finished, as of the sponsor's last update on 20 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States, Netherlands, United Kingdom. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Risk Stratification (time frame: Baseline). 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 Dec 2016.
