Active clinical trials for "Barrett Esophagus"

The aim of this study is to assess the safety and feasibility of the EndoRotor® for the ablation of Barrett's esophagus.

Background and study aims. To evaluate the impact of power setting and proton pump inhibitor (PPI) dose on the efficacy and safety of argon plasma coagulation (APC) of Barrett's esophagus (BE) with low-grade dysplasia (LGD). Patients and methods. Investigator initiated, single-center, parallel-group randomized controlled trial (RCT) conducted in a tertiary referral center in Poland. Consecutive patients with BE and LGD were randomly assigned to APC with power set at 90 Watt (90W) or 60 Watt (60W) followed by 120 mg or 40 mg omeprazole for six weeks. The primary outcome of the study was the rate of complete (endoscopic and histologic) ablation of BE at six weeks. Secondary outcomes included safety and long-term efficacy (at two years and at the end of a long-term follow-up of over 4 years.

The purpose of the study is to compare the treatment of esomeprazole 40 mg once daily and lansoprazole 30 mg once daily in controlling intragastric pH in Barrett's Esophagus patients

The overall aim of this feasibility study is to develop new technologies for improved detection of Barrett's neoplasia using the scanning fiber endoscope (SFE) imaging system. This study will combine the use of a fluorescent-labeled peptide dimer that bind specifically to pre-cancerous mucosa in the esophagus for use as a novel imaging agent to guide endoscopic biopsy or endoscopic mucosal resection (EMR). This Phase 1B study will be used to provide early evidence of efficacy for the topical application of a peptide dimer that binds to molecular targets, including EGFR and HER2, that are specific for esophageal dysplasia. A dimer is needed because cancer in the esophagus is genetically heterogeneous. QRH binds specifically to Epidermal Growth Factor Receptor (EGFR), and KSP binds specifically to Human Epithelial Growth Factor Receptor (HER2). The study will look at peptide binding in subjects with known or suspected Barrett's esophagus.

This study is being done to understand the effect of dietary omega-3 fats in decreasing tissue inflammation in Barrett's esophagus.

Neoplasia in Barrett's esophagus could be missed during routine random biopsies. We propose a study using chromoendoscopy with Acetic Acid to increase the yield of biopsies in detecting neoplasia.

A phase 2, randomised, double-blind, out-patient trial to determine if YF476 is a safe and effective treatment in patients with Barrett's esophagus.

The purpose of this study is to evaluate the treatment effect, depth of injury, and side effects using technology involving the spray of liquid nitrogen through a catheter (CryoSpray AblationTM, "CSA" or "cryospray therapy") onto healthy tissue via esophagogastroduodenoscopy (EGD) using surgical resection specimens from subjects undergoing esophagectomy.

This is a single center study to evaluate the efficacy and safety of a new ablation technique involving the spray of liquid nitrogen through a catheter (cryotherapy) via an upper endoscopy (EGD) to ablate Barrett's esophagus with changes of high-grade dysplasia (HGD) or intramucosal cancer (IMCA) and patients with esophageal cancer limited to the esophageal wall, in whom there are no standard treatment options available.

Barrett's oesophagus is a pre-cancerous condition in which normal cells in the lining of gullet undergo cell changes and this increases the risk of developing adenocarcinoma (a type of cancer) of the gullet. This type of cancer is the 5th most common type of cancer in the UK. To minimise this risk of developing cancer, patients with Barret's oesophagus have regular gastroscopy (a small camera at the tip of the slim tube) every 2-5 years to detect early cancer cell changes. During the procedure, the whole of oesophagus is carefully inspected, and small tissue samples (biopsies) are taken from visible abnormal area within Barrett's oesophagus and sent to the lab to check for cell changes. This is called targeted biopsies. As the endoscopist cannot always tell during gastroscopy where cells are changing, biopsies from each quarter of the gullet (called quadrantic biopsies) are also taken to reduce the risk of pre-cancerous cells being missed. However, this process is time consuming and expensive as numerous biopsies are required. Recently, there has been a huge development in artificial intelligence (AI). One of these developments is the aid of computer to detect (called computer-aided detection - CAD) the abnormal cell changes within Barrett's during gastroscopy. This system has recently been trained and tested on videos and photos to prove that its performance is as good as expert endoscopists. This system has been already approved to use in the UK. However, this system needs to be tested further and incorporated into real life use to prove that the CAD is useful in detecting cell changes during gastroscopy for targeted biopsies and therefore, the random biopsies can be avoided. A sample of patients with Barrett's oesophagus will be invited to participate in this study. Participants will have a gastroscopy as part of their usual care for Barrett's oesophagus. Endoscopist will inspect Barrett's oesophagus using AI and will take both targeted biopsies if clinically deemed appropriate along with quadrantic biopsies. Participants will continue to receive usual care and no additional follow up or procedures will be required as part of the study.
