Cytosponge Procedure
for Barrett's Esophagus
This clinical trial evaluates the use of cytosponge, a minimally invasive collection device, for the detection of Barrett's esophagus (BE) in patients undergoing endoscopy. Non-endoscopic swallowable encapsulate sponge cell collection devices combined with markers for BE/esophageal adenocarcinoma (EAC) detection are a guideline-endorsed alternative to endoscopy for BE screening. The Oncoguard registered trademark Esophagus test (OGE) test uses esophageal cytology specimens collected with a minimally invasive, non-endoscopic, encapsulated sponge sampling device to identify BE/EAC biomarkers that indicate whether a patient should undergo diagnostic endoscopy. The OGE test is a simple and cost effective screening method that may lower barriers to widespread adoption of BE screening in at risk patients, resulting in increased and earlier detection of BE/EAC.

WATS3D vs Seattle Protocol
for Barrett's Esophagus
The purpose of this research study is to learn about the best approach to sample patients with known or suspected Barrett's esophagus (BE) by comparing the standard Seattle biopsy protocol to sampling using wide area transepithelial sampling (WATS3D). Barrett's esophagus is a common condition that is used to spot patients at increased risk of developing a type of cancer in the esophagus (swallowing tube) called esophageal adenocarcinoma. The 5-year survival rate is as low as 18% for patients who get esophageal adenocarcinoma, but the rate may be improved if the cancer is caught in its early stages. Barrett's esophagus can lead to dysplasia, or precancerous changes, which occurs when cells look abnormal but have not developed into cancer. If the abnormal cells increase from being slightly abnormal (low-grade dysplasia), to being very abnormal (high-grade dysplasia), the risk of developing cancer (esophageal adenocarcinoma) goes up. Therefore, catching dysplasia early is very important to prevent cancer. Endoscopic surveillance is a type of procedure where endoscopists run a tube with a light and a camera on the end of it down a 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. Patients are being asked to be in this research study because they have been diagnosed with BE or suspected to have BE, and will need an esophagogastroduodenoscopy (EGD). Patients with BE undergo sampling using the Seattle biopsy protocol during which samples are obtained from the BE in a four quadrant fashion every 2 cm along with target biopsies from any abnormal areas within the BE. Another sampling approach is WATS3D which utilizes brushings from the BE. While both of these procedures are widely accepted approaches to sampling patients with BE during endoscopy, there is not enough research to show if one is better than the other. Participants in this study will undergo sampling of the BE using both approaches (Seattle biopsy protocol and WATS-3D); the order of the techniques will be randomized. Up to 2700 participants will take part in this research. This is a multicenter study involving several academic, community and private hospitals around the country.

Frequently asked questions
Do I need insurance to participate in a trial?
Almost all clinical trials will cover the cost of the ‘trial drug’ — so no insurance is required for this. For trials where this trial drug is given alongside an already-approved medication, there may be a cost (which your insurance would normally cover).
