Filter by:This clinical study is a Phase 2, open-label study to assess the efficacy, safety profile of FLX475 combined with pembrolizumab in patients with advanced or metastatic gastric cancer. This study is designed to assess the potential anti-tumor activity when administered at the 100mg QD of FLX475 with pembrolizumab and will be conducted (2) cohorts as detailed below. - Cohort 1: EBV negative / CPI naïve gastric cancer subjects who have progressed on at least 2 prior systemic treatments for advanced or metastatic gastric cancer - Cohort 2: EBV positive / CPI naïve gastric cancer subjects who had at least 1 prior systemic treatment for advanced or metastatic gastric cancer Approximately 90 subjects may be enrolled across two cohorts to examine the safety and efficacy.
Introduction: Traditionally, White Light Endoscopy (WLE), enhanced by biopsies following the updated Sydney system guidelines, has been the benchmark for diagnosing and classifying gastric preneoplastic conditions. Nevertheless, the pronounced interobserver variability and the often weak correlation between endoscopic observations and histopathological results have driven the increasing adoption of virtual chromoendoscopy (VCE). VCE technologies have demonstrated greater effectiveness in identifying these conditions compared to WLE, with Narrow Band Imaging (NBI) being particularly notable. Significantly, NBI has played a key role in validating the Endoscopic Grading of Gastric Intestinal Metaplasia (EGGIM) system. However, data on the effectiveness of other VCE technologies in this domain is relatively sparse in Europe, specifically with Blue Light Imaging (BLI), despite the promising diagnostic performance demonstrated with this technology. Primary aim: to assess the diagnostic accuracy of BLI and to externally validate the applicability of EGGIM classification for staging GIM. Material and methods: a multicentric cohort study will be performed involving centres from two European countries (Portugal, Italy). Consecutive patients performing upper gastrointestinal endoscopy will be evaluated by WLE and BLI. Random biopsies or targeted plus random biopsies will be performed in order to determine de accuracy of BLI system to detect and stage GIM. Expected results: We anticipate that BLI would enable us to assess the extension of GIM without the need for biopsies. If observed, this would overall improve the upper GI endoscopy accuracy.
This is a Phase Ib/II, multicenter, open-label study to evaluate the safety and preliminary efficacy of TT-00420 tablet, as monotherapy or in combination regimens, in patients with advanced solid tumors.
This pilot and feasibility study will be first US study to determine if a magnetically controlled capsule (MCC) can effectively visualize the anatomy of the stomach like a more traditional upper endoscopy (EGD). This study is designed to enroll participants who have a standard indication for an EGD and are also willing to get an MCC exam. The MCC is driven actively by a clinician unlike prior capsule endoscopes that move passively by gravity or peristalsis. Thus, a physician will be able to look more closely at areas of the stomach that might be concerning and might need further evaluation and/or treatment.
This study aims at evaluating efficacy and safety of berberine hydrochloride, amoxicillin and rabeprazole triple therapy versus bismuth-containing quadruple therapy(amoxicillin, clarithromycin, rabeprazole and bismuth) in the first eradication treatment of H. pylori. It is hypothesized that berberinehydrochloride, amoxicillin and rabeprazole triple therapy is non-inferior to bismuth-containing quadruple therapy. Patients diagnosed with H. pylori infection will be randomly divided into one of the above treatments. At week 6 follow-up visits, a urea breath test，rapid urease test or helicobacter pylori stool antigen test will be performed to confirm eradication.
A multicenter Italian retrospective study on COVID-19 pandemic condition and advanced Gastro - Intestinal Cancer. Are in Italy increased the new diagnosis of GI cancer in advanced stage in the 2020 compared with 2019, as a consequence of COVID-19?
This study aims at evaluating efficacy and safety of high-dose esomeprazole and amoxicillin dual therapy(esomeprazole and amoxicillin) versus bismuth-containing quadruple Therapy(bismuth，esomeprazole，tetracycline and furazolidone) in H. pylori rescue therapy. It is hypothesized that high-dose esomeprazole and amoxicillin dual therapy is non-inferior to bismuth-containing quadruple Therapy. Patients with confirmed failure of H. pylori eradication will be randomized to one of the treatments described above. At week 6 follow-up visits, a urea breath test，rapid urease test or helicobacter pylori stool antigen test will be performed to confirm eradication.
Gastric outlet obstruction in malignant disease appears when the tumor affects the gastroduodenal area, precluding the passage of food into the small bowel. This condition severely affects the quality of life. In patients with unresectable tumors, there are various available treatments:a surgical bypass connecting the stomach to the small bowel, placing a stent through the tumor to widen the passage and creating a gastrointestinal bypass with a lumen apposing metal stent. These stents are deployed with an echoendoscope, which allows to identify a small bowel loop and to deploy the stent, connecting the small bowel and the stomach. This is called a EUS-guided gastroenterostomy (EUS-GE). EUS-GE is a rather novel procedure. Various techniques to create EUS-GE have been proposed. In this study, the investigators will retrieve data from the procedure and during the thirty following days from consecutive patients undergoing an EUS-GE. The objectives of the study are: - To perform a detailed step by step description of the nasobiliary drain assisted EUS-GE - To describe the adverse events encountered - To describe the proportion of clinical and technical success - To assess its impact on the patients' quality of life. - To assess the evolution of the oral intake during the first month after the procedure
To observe the eradication rate of H. pylori infection, symptom improvement and the incidence of adverse effects in patients using a bismuth colloidal pectin granules quadruple therapy.
To explore the associations among bile acid profile, bile acid-microbiota cross-talk and the development of gastric cancer, so as to better prevent the occurrence and development of gastric cancer
