Active clinical trials for "Barrett Esophagus"

Barrett's esophagus with high-grade dysplasia is a premalignant condition caused by chronic reflux of gastric contents into the esophagus. High-grade dysplasia is the same as carcinoma-in-situ. If untreated, patients with this condition are at high risk for developing cancer of the esophagus. Cancer of the esophagus is a miserable disease that is difficult to treat and about 95% fatal after 5 years. To prevent progession to cancer of the esophagus several interventions are available and they include surgery, Photofrin photodynamic therapy, endoscopic mucosal resection and endoscopic thermal therapy. All of these modalities are uncomfortable, expensive and have associated risks. The oral agent, 852A stimulates the innate immune system in such a way as to eliminate early cancer. A similar dermatologic drug(imiquimod) is approved for treating the premalignant condition, actinic keratosis. If local therapy with imiquimod can eliminate a premalignant lesion in the skin, a similar acting drug should be able to do the same for a premalignant lesion in the lining of the esophagus. This study is designed to test that hypothesis.

The purpose of this research is to test the feasibility, sensitivity, and specificity of the marking Optical Frequency Domain Imaging (OFDI) capsule for diagnosing Barrett's Esophagus (BE).

The goal of this research is to follow Barrett's Esophagus patients for 3 years using the tethered capsule endomicroscopy device with distal scanning and a compact imaging system in a multi-site clinical study.

To evaluate association between mutational load (ML) from esophageal biopsy specimens in pre-endoscopic eradication therapy (EET) in Barrett's Esophagus (BE) or Intramucosal adenocarcinoma (IMC) patients and treatment resistance (treatment resistance will be defined as disease recurrence and/or need for additional intervention such as increased acid suppression, need for anti-reflux surgery, or use of alternate ablative modality).

The purpose of this study is to evaluate the safety and effectiveness of the CryoSpray Ablation System to treat esophageal low grade dysplasia (LGD) or high grade dysplasia (HGD) within Barrett's Esophagus (BE).

This study is designed to evaluate the effect of dexlansoprazole once daily (QD) and twice daily (BID) dosing on the recurrence of intestinal metaplasia (IM) in participants who achieved complete eradication of Barrett's esophagus (BE) with high-grade dysplasia (HGD) following radiofrequency ablation (RFA).

This study aims to evaluate the acceptability of a new non-invasive screening device to test for Barrett's esophagus. The investigators will prospectively enroll 100 patients to undergo Cytosponge testing. The time of involvement for an individual will range from 2 weeks to 2 months, depending on the results of the Cytosponge test and time to follow up endoscopy, if indicated.

To determine whether sorafenib is able to change pre-cancerous cells in a way that we believe is important in the progression of cancer.

The purpose of this pilot study is to provide an initial assessment of the feasibility, safety and efficacy of Polar Wand carbon dioxide cryotherapy for treatment of Barrett's low grade and high grade dysplasia by use in a small number of patients so as to support, or otherwise, the development of a full-scale trial.

Aim 1: To develop a prospective tissue and blood biorepository from patients with a history of Barrett's Esophagus (BE) or esophageal cancer (ECA) presenting to UNC hospitals for routine care upper endoscopy for their condition. Aim 2: To collect clinical data from patients with a history of Barrett's Esophagus (BE) or esophageal cancer (ECA) that includes demographic data, endoscopic procedure data, and pathology data. Aim 3: To integrate Aim 1 and 2 in a manner that will provide an efficient bi-directional flow of clinical information and specimens between laboratory and clinical scientists in order to foster innovative translational research. Aim 4: To create a biorepository for future Institutional Review Board (IRB) approved studies that have tissue and/or blood specimen component.
