About this study
Official title: Barrett's Esophagus Early Detection Study
Background:
The incidence rate for esophageal adenocarcinoma (EAC) has risen 10% per year over the past two decades and is the most rapidly increasing cancer in the U.S.
Read more
Barrett's esophagus (BE), a metaplastic change from the normal squamous esophageal epithelium to a specialized intestinal-type columnar mucosa, increases the risk of EAC by 30-125, and is considered a precursor lesion for EAC.
Individuals diagnosed with BE are currently entered into endoscopic surveillance programs to look for dysplasia or EAC. However, only 5% of subjects diagnosed with EAC have a previous diagnosis of BE or have been part of a surveillance program, so alternative screening methods are needed.
Objectives:
The primary goal of this project is to identify a practical blood-based biomarker(s) that can be used as a screening test to determine who has BE and who does not.
Secondary goals of the project are to characterize germ-line and tissue biomarkers associated with BE, and to compare biomarkers in non-BE patients with and without GERD.
Tertiary goals are to explore associations between biomarkers in blood or tissue and progression from BE to dysplasia or EAC, and to assess the stability of proteomic patterns over time.
Eligibility:
This study will be conducted among patients in the Barrett's Esophagus Registry (currently with 206 registrants) established at the National Naval Medical Center (NNMC) in Bethesda beginning in 1992, as well as a comparison group of approximately 600 matched non-BE patients endoscoped in the GI clinic at NNMC for other conditions.
Design:
Blood and tissue samples will be collected as well as questionnaire data on risk factors and medications as well as GERD.
Data analyses will be based primarily on laboratory testing of newly collected esophageal biopsies, brush samples, and blood samples, but secondarily will also include use of archival tissue biopsy samples.
Follow up of BE Registry patients will include standard periodic surveillance endoscopies, additional blood samples, and ascertainment of disease status (i.e., progression).
To distinguish BE versus non BE-patients in this case-control study, we will:
assess predictability of BE status from serum proteomic patterns;
characterize esophageal biopsies and brush samples for selected DNA alterations, RNA expression, and proteomic profiles;
genotype patients for selected polymorphisms potentially associated with BE;
compare blood and tissue biomarkers in non-BE patients with and without GERD;
explore the association of biomarkers with progression from BE to dysplasia or EAC;
assess proteomic pattern stability over time in BE patients.

Background:
The incidence rate for esophageal adenocarcinoma (EAC) has risen 10% per year over the past two decades and is the most rapidly increasing cancer in the U.S.
Barrett's esophagus (BE), a metaplastic change from the normal squamous esophageal epithelium to a specialized intestinal-type columnar mucosa, increases the risk of EAC by 30-125 fold (1), and is considered a precursor lesion for EAC.
Individuals diagnosed with BE are currently entered into endoscopic surveillance programs to look for dysplasia or EAC. However, only 5% of subjects diagnosed with EAC have a previous diagnosis of BE or have been part of a surveillance program, so alternative screening methods are needed.

Tertiary goals are to explore associations between biomarkers in blood or tissue and progression from BE to dysplasia or EAC, and to assess the stability of proteomic patterns over time.
Eligibility:
This study will be conducted among patients in the Barretts Esophagus Registry (currently with 206 registrants) established at the National Naval Medical Center (NNMC) in Bethesda beginning in 1992 as well as comparison group of approximately 600 matched non-BE patients endoscoped in the GI clinic at NNMC for other conditions.

Follow-up of BE Registry patients will include standard periodic surveillance endoscopies, additional blood samples, and ascertainment of disease status (i.e, progression).
To distinguish BE versus non-BE patients, we will: (1) assess predictability of BE status from serum proteomic patters; (2) characterize esophageal biopsies and brush samples for selected DNA alterations, RNA expression, and proteomic profiles; (3) genotype patients for selected polymorphisms potentially associated with BE; (4) compare blood and tissue biomarkers in non-BE patients with and without GERD; (5) explore the association of biomarkers with progression from BE to dysplasia or EAC; and (6) assess proteomic pattern stability over time in BE patients.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Background:
The incidence rate for esophageal adenocarcinoma (EAC) has risen 10% per year over the past two decades and is the most rapidly increasing cancer in the U.S.
Barrett's esophagus (BE), a metaplastic change from the normal squamous esophageal epithelium to a specialized intestinal-type columnar mucosa, increases the risk of EAC by 30-125, and is considered a precursor lesion for EAC.

Objectives:
The primary goal of this project is to identify a practical blood-based biomarker(s) that can be used as a screening test to determine who has BE and who does not.
Secondary goals of the project are to characterize germ-line and tissue biomarkers associated with BE, and to compare biomarkers in non-BE patients with and without GERD.
Tertiary goals are to explore associations between biomarkers in blood or tissue and progression from BE to dysplasia or EAC, and to assess the stability of proteomic patterns over time.

Follow up of BE Registry patients will include standard periodic surveillance endoscopies, additional blood samples, and ascertainment of disease status (i.e., progression).
To distinguish BE versus non BE-patients in this case-control study, we will:
assess predictability of BE status from serum proteomic patterns;

Questions about this trial
What is this clinical trial studying?
An observational study of Barrett's Esophagus, run by National Cancer Institute (NCI) at 1 site in United States.
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 7 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 22 May 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 United States. 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?
Case Control (time frame: End of Study). 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 NCT00081354, which also lists 3 linked publications.
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 22 May 2020.
