About this trial

The purpose of this study is to learn the best approach to treating patients with known or suspected Barrett's esophagus by comparing endoscopic surveillance to endoscopic eradication therapy.

To diagnose and manage Barrett's esophagus and low-grade dysplasia, doctors commonly use procedures called endoscopic surveillance and endoscopic eradication therapy. Endoscopic surveillance is a type of procedure where a physician will run a tube with a light and a camera on the end of it down the patients throat and remove a small piece of tissue. The piece of tissue, called a biopsy, is about the size of the tip of a ball-point pen and is checked for abnormal cells and cancer cells.

Endoscopic eradication therapy is a kind of surgery which is performed to destroy the precancerous cells at the bottom of the esophagus, so that healthy cells can grow in their place. It involves procedures to either remove precancerous tissue or burn it. These procedures can have side effects, so it is not certain whether risking those side effects is worth the benefit people get from the treatments.

While both of these procedures are widely accepted approaches to managing the condition, there is not enough research to show if one is better than the other.

Barrett's esophagus and low-grade dysplasia does not always worsen to high-grade dysplasia and/or cancer. In fact, it usually does not. So, if a patient's dysplasia is not worsening, doctors would rather not put patients at risk unnecessarily. On the other hand, endoscopic eradication therapy could possibly prevent the worsening of low-grade dysplasia into high-grade dysplasia or cancer (esophageal adenocarcinoma) in some patients. Researchers believe that the results of this study will help doctors choose the safest and most effective procedure for their patients with Barrett's esophagus and low-grade dysplasia.

This is a multicenter study involving several academic, community and private hospitals around the United States. Up to 530 participants will be randomized. This study will also include a prospective observational cohort study of up to 150 Barrett's esophagus and low grade dysplasia patients who decline randomization in the randomized control trial but undergo endoscopic surveillance (Cohort 1) or endoscopic eradication therapy (Cohort 2), and are willing to provide longitudinal observational data.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Male or female, age ≥18 years;

Subject has endoscopic evidence of Barrett's esophagus characterized by the presence of salmon-colored mucosa in the tubular esophagus of at least 1 cm in length as well as endoscopic biopsies from the involved areas demonstrating columnar metaplasia with goblet cells. This inclusion criterion will exclude patients with intestinal metaplasia with dysplasia of the gastric cardia;

Biopsies within the previous 12 months demonstrating Barrett's esophagus and indeterminate for dysplasia or low grade dysplasia;

Confirmation of low grade dysplasia by expert central pathology panel from biopsies obtained within the previous 12 months;

Disqualifiers

Pregnancy;

Prior endoscopic eradication therapy for Barrett's esophagus;

History of high grade dysplasia or esophageal adenocarcinoma;

History of esophageal resection/esophagectomy

Treatments tested in this trial

  • Endoscopic Eradication Therapy

    Procedure/Surgery

    Endoscopic eradication therapy is a procedure performed to destroy the precancerous cells at the bottom of your esophagus, so that healthy cells can grow in their place. It involves procedures to either remove precancerous tissue or burn it. These procedures are performed through the endoscope.

Trial outcomes

Primary outcomes

1

Neoplastic Progression

The occurrence of high grade dysplasia/mucosal post-endoscopy esophageal adenocarcinoma/invasive post-endoscopy esophageal adenocarcinoma at any time during the study period following enrollment.

Time frame
Baseline, through study completion

Secondary outcomes

1

Work Productivity and Activity

The Work Productivity and Activity Index (WPAI) is a 6-item questionnaire that has been adapted to address the impact of reflux symptoms on work and activity burden. Patient-centered outcomes (PCOs) have been defined and prioritized by key stakeholders (patients, caregivers, clinicians) and will be compared in Barrett's esophagus patients with low grade dysplasia treated with endoscopic eradication therapy to those undergoing surveillance.

Time frame
Baseline, through study completion
2

Biomarker Utility

Three biomarkers of interest (p53, TissueCypher and WATS3D) will be collected to examine the relationship between biomarker results and the primary efficacy outcome.

Time frame
Baseline, through study completion
3

Esophageal Adenocarcinoma (EAC) progression rate

The proportion of subjects that progress to a diagnosis of invasive post-endoscopy esophageal adenocarcinoma alone during follow up

Time frame
Baseline, through study completion
4

Patient-Reported Depression, Anxiety, and Gastrointestinal Symptoms

NIH PROMIS measures (fixed, short-forms) will be used to measure the following constructs: Depression (4 items), Anxiety (8 items), Gastrointestinal Symptoms (13 items dedicated to GERD) and Global Health (10 items). Patient-centered outcomes (PCOs) have been defined and prioritized by key stakeholders (patients, caregivers, clinicians) and will be compared in Barrett's esophagus patients with low grade dysplasia treated with endoscopic eradication therapy to those undergoing surveillance.
