SOS4C Trial Summary

This trial studies a new minimally invasive test to detect Barrett's Esophagus, a precursor to cancer, to make it easier to detect and treat earlier.

Who is the study for?
This trial is for adults aged 18-90 with Barrett's Esophagus (BE) or suspected BE, who are undergoing endoscopy. It includes those without a known history of BE and excludes pregnant women, individuals unable to consent, patients on certain blood thinners unless stopped before the procedure, and those with specific esophageal conditions or past foregut cancer.Check my eligibility
What is being tested?
The trial tests a minimally invasive Cytosponge device against standard endoscopic assessment for detecting BE. The Cytosponge collects cells from the esophagus to identify biomarkers indicative of BE/esophageal adenocarcinoma using the Oncoguard Esophagus test.See study design
What are the potential side effects?
Potential side effects may include discomfort from swallowing the Cytosponge device and minor bleeding. There could also be risks associated with endoscopic procedures such as sore throat, infection risk, and very rarely perforation.

SOS4C Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Known or Suspected Barrett's Esophagus (Case Arm)Experimental Treatment2 Interventions
Investigators will follow Cytosponge Cell Collection Kit Instructions for Use to administer and retrieve the Cytosponge device.c. After the sponge is retrieved, it will then be placed in a vial of cell preservative solution (PN DD-13631, Exact Sciences, Madison, WI) and shipped to the Exact Sciences laboratory for further processing and subsequent analysis.
Group II: No Known Barrett's Esophagus (Control Arm)Active Control2 Interventions
Participants will undergo a diagnostic clinically indicated sedated endoscopy with standard endoscopic equipment.
