Early Detection of Barrett's Esophagus in Participants With Reflux Symptoms in Primary Care

Barrett EsophagusEsophageal Cancer

In the Netherlands, the incidence of esophageal adenocarcinoma (EAC) is increasing. In addition, EAC has a dismal prognosis. Therefore, screening for Barrett's Esophagus (BE) has stimulated interest. Although BE is a known precursor of EAC, a minority of patients with EAC are known with a previous diagnosis of BE. A non-invasive screening tool, such as breath testing, could select patients at risk for BE, after which unsedated transnasal endoscopy (uTNE) can confirm or exclude the diagnosis. The objective is to determine the accuracy and acceptability of a non-invasive screening strategy i.e. breath testing followed by uTNE for BE and EAC.

Obeticholic Acid for Prevention in Barrett's Esophagus

Barrett Esophagus

This phase II trial studies the effect of obeticholic acid in treating patients with Barrett's esophagus. Bile acids present in duodenogastroesophageal reflux contribute to neoplastic progression in Barrett's esophagus. Obeticholic acid has shown anti-cholestatic, anti-inflammatory and anti-fibrotic effects mediated by FXR activation. It down regulates bile acid availability and decreases proinflammatory cytokine production including IL-1β and TNFα in human enterocytes and immune cells. This chain of events reduces the bile acid exposure in esophagus tissue thereby limiting bile acid induced damage and dysplastic progression.

Itraconazole to Prevent Recurrent Barrett's Esophagus

Barrett Oesophagitis With Dysplasia

Recurrent Barrett's esophagus (BE) that occurs at the rate of 12.4%/year is the Achilles heel of the endoscopic treatment of high-risk BE. Over time, after eradication, BE ultimately recurs in as many as 30-50% of the patients putting them at risk for esophageal adenocarcinoma (EAC), thereby undoing the benefits of an effective initial therapy. Also, recurrences need retreatments that increase costs and complications including strictures and refractory ulcerations. A therapy to prevent recurrent BE does not currently exist. Itraconazole with its ability to inhibit important molecular pathways related to BE development could enhance the long-term effectiveness of endoscopic eradication of high-risk BE, thereby promoting a long-term cure

Seattle Biopsy Protocol Versus Wide-Area Transepithelial Sampling in Patients With Barrett's Esophagus...

Barrett EsophagusBarretts Esophagus With Dysplasia1 more

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.

Assessment of a Minimally Invasive Collection Device for Molecular Analysis of Esophageal Samples...

Barrett EsophagusBarretts Esophagus With Dysplasia2 more

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.

High Resolution Virtual Chromoendoscopy Versus Seattle Protocol for the Surveillance of Barrett's...

Barrett Esophagus

The investigators hypothesize that careful examination of Barrett's esophagus by high-resolution endoscopy combined with virtual chromoendoscopy could replace the Seattle protocol for Barrett's esophagus monitoring and detection of dysplasic lesions, and thus modify existing recommendations.

This study seeks to incorporate non-endoscopic detection method (Esocheck/Esoguard) in primary care practice and test whether this screening modality increases the positive predictive value of upper endoscopy and increases the detection of Barrett's esophagus and esophageal cancer.

GCC Agonist Signal in the Small Intestine

Barrett EsophagusGastroesophageal Reflux Disease1 more

This early phase I trial studies the guanylyl cyclase C (GCC) agonist effect on cGMP signal in duodenal tissue. Plecanatide and linaclotide are drugs approved by the Food and Drug Administration for the treatment of conditions related to constipation. This trial aims to see the effects of taking either one of two drugs, plecanatide or linaclotide, or no drug, on a certain chemical found in the tissue collected from small intestine and how they compare.

The Prevalence, Risk Factors and Optimal Biopsy Protocol of BE

Barrett's EsophagusIntestinal Metaplasia

Detections of goblet cells and dysplasia are crucial for diagnosis and determining the surveillance program of Barrett's esophagus (BE). However, the optimal biopsy numbers and their yield rates of intestinal metaplasia (IM) and dysplasia are still uncertain, especially in Asia. The aim of this study was to determine the optimal biopsy protocol of BE.
