Minimally Invasive Approaches for the Diagnosis of Barrett's Esophagus and Esophageal Cancer, SOS5C Trial

United States1,010 participantsStarted 2026-12-01

Plain-language summary

This clinical trial studies how well minimally invasive approaches (an artificial intelligence \[AI\] powered risk tool, nurse navigation, and a sponge on a string \[SOS\] test) work in diagnosing patients with Barrett's esophagus (BE) and esophageal cancer. Esophageal cancer has a poor 5-year survival rate when diagnosed after onset of symptoms. While rising, incidence of esophageal cancer remains too low to screen the entire population. BE is a condition in which the cells lining the lower part of the esophagus have changed or been replaced with abnormal cells that could lead to esophageal cancer. Currently, patients are screened for BE based on certain risk factors (reflux, age \> 50 years, White race, family history of esophageal cancer, obesity, male sex, and smoking), followed by endoscopies and surgery for treatment. These standard procedures may result in under-recognition of BE risk due to inaccurate and difficult to use risk assessment tools, high cost, invasiveness, low access to endoscopy, and sub-optimal recognition of abnormal cells during routing endoscopy. An AI powered risk tool that integrates symptoms, health history, and laboratory values from electronic health record data may more accurately assess BE and esophageal cancer risk that manual assessment. The BE-SOS screening test combines a swallowable cell collection device with assessment of DNA, which may more accurately diagnose abnormal cells. Nurse navigation involves trained personnel assisting individuals through the screening process and completing the follow-up diagnostic test if the screening test is positive. Navigators address cultural, social, access, and logistical barriers to screening. Nurse navigation may increase completion rates of diagnostic procedures following a positive screening test. These minimally invasive approaches may enable higher rates of BE screening than currently being accomplished.

Inclusion Criteria: * SPECIFIC AIM 1A: Adult patients 18-85 years old * SPECIFIC AIM 1A INTERVENTION CLUSTERS: BE Risk Tool Score \> 0.087, indicating a higher risk for BE/esophageal adenocarcinoma (EAC). This will be run as a web-based application integrating data from several domains in the electronic health record (EPIC). Output score will range from 0-1. * SPECIFIC AIM 1A CONTROL CLUSTERS: Meeting American College of Gastroenterology (ACG) screening criteria (gastroesophageal reflux disease \[GERD\]+ \> 2 BE risk factors: Age ≥ 50 years, Male sex, Caucasian race, obesity \[body mass index (BMI) \> 30\], ever smoker, family history of BE/EAC) * SPECIFIC AIM 1B: A "low risk" BE risk tool score (\< 0.0897) Exclusion Criteria: * SPECIFIC AIM 1A: History of Barrett's esophagus or esophageal adenocarcinoma * SPECIFIC AIM 1A: Prior endoscopy in the last 10 years * SPECIFIC AIM 1A: Patients who are unable to consent * SPECIFIC AIM 1A: Patients with a current history of uninvestigated dysphagia * SPECIFIC AIM 1A: History of eosinophilic esophagitis, achalasia * SPECIFIC AIM 1A: Patients on oral anticoagulation including Coumadin, Warfarin unless discontinued for five days prior to the sponge procedure * SPECIFIC AIM 1A: Patients on antiplatelet agents including Clopidogrel, unless discontinued for five days prior to the sponge procedure * SPECIFIC AIM 1A: Patients on oral thrombin inhibitors including Dabigatran and oral factor Xa inhibitors such as rivaroxaban, apixaban, and e…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
