NCT ID: NCT06267703 Active, not recruiting - Clinical trials for Chronic Atrophic Gastritis

Multi-omics Analyses on Etiology and Early Detection of Stomach Cancer Precursor Lesions

Start date: January 1, 2024
Phase:
Study type: Observational [Patient Registry]

The overall aim is to utilize multi-omics approach to identify novel etiopathogenesis and early detection biomarkers for stomach cancer precursor lesions. To achieve this aim, first the investigators will use stored serum samples to perform metabolomics profiling among 12,599 twin subjects, among whom 1034 were deemed to have chronic atrophic gastritis based on measured pepsinogen I and II levels. Logistic regression will be used to search for metabolites related to the risk of chronic atrophic gastritis. Second, the investigators will further measure serum proteome by using two quantitatively precise proteomics assays, among the above-mentioned twin subjects. Identified protein biomarkers will be combined with metabolomics biomarkers to create a prediction model for chronic atrophic gastritis. The results will hopefully improve our understanding of the etiological factors and provide promising early detection biomarkers for stomach cancer precursor lesions.

NCT ID: NCT06085677 Not yet recruiting - Stomach Neoplasm Clinical Trials

The Gastric HormonE BioMarkers of Preneoplastic Lesions Study

GEM
Start date: November 4, 2023
Phase:
Study type: Observational

The goal of the study is to understand whether blood levels of hormones produced or metabolized in the stomach reflect the health of the stomach lining. Specifically the study will determine whether the concentration of ghrelin, gastrin, pepsinogens and vitamin B12 reflect the condition of the stomach lining. Hormone concentrations for people with normal/mild gastritis will be compared to people with long-term inflammation of the stomach (chronic atrophic gastritis), and people with pre-cancerous cellular changes (intestinal metaplasia).

NCT ID: NCT05388890 Recruiting - Clinical trials for Chronic Atrophic Gastritis

Treatment of Atrophic Gastritis After HP Eradication With Modified Liujunzi Decoction Based on Syndrome Differentiation

Start date: August 2, 2022
Phase:
Study type: Observational

This is an observational cohort study of clinical efficacy study.The purpose of this topic is to evaluate the efficacy and safety of Modified Liujunzi Decoction based on syndrome differentiation in patients with chronic atrophic gastritis(CAG) after HP eradication.Taking Modified Liujunzi Decoction as the observation group and Weifuchun routine treatment as the control group, so as to provide evidence for the treatment of CAG and reduce the risk of gastric cancer. A total of 284 patients were included. The curative efficacy, symptom score and adverse events will be recorded and analyzed.

NCT ID: NCT03597672 Recruiting - H. Pylori Infection Clinical Trials

Early Detection and Screening Strategy of Gatric Cancer in Sichuan Province-A Prospective Cohort Study (WCH-GC-SIGES-01)

SIGES-01
Start date: January 1, 2017
Phase:
Study type: Observational

To establish prospective cohort of healthy population and corresponding serum sample bank in Sichuan province to provide platform for exploring early diagnosis and screening strategy of gastric cancer by a prospective cohort study.

NCT ID: NCT02955134 Completed - Clinical trials for Chronic Atrophic Gastritis

The Study of Chinese Medicine for the Treatment of Chronic Atrophic Gastritis

Start date: March 12, 2018
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate efficacy of Chinese medicine treatment for chronic atrophic gastritis. It is a multi-center, randomized, placebo-controlled trial.

NCT ID: NCT02782949 Active, not recruiting - Clinical trials for Chronic Atrophic Gastritis

Curcumin in Preventing Gastric Cancer in Patients With Chronic Atrophic Gastritis or Gastric Intestinal Metaplasia

Start date: April 4, 2017
Phase: Phase 2
Study type: Interventional

This randomized phase IIb trial studies how well curcumin works in preventing gastric cancer in patients with chronic atrophic gastritis and/or gastric intestinal metaplasia. Curcumin is an antioxidant compound found in plants that may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

NCT ID: NCT01444014 Terminated - Clinical trials for Chronic Atrophic Gastritis

YF476 and Type I Gastric Carcinoids (Norway)

Start date: June 2011
Phase: Phase 2
Study type: Interventional

The aim of the study is to find out if the experimental medicine, YF476, can make gastric carcinoids, a rare type of stomach tumour, shrink and disappear. Gastric carcinoids occur mainly in patients with chronic atrophic gastritis (CAG), a condition in which the acid-producing cells in the lining of the stomach can't make acid. Acid production is controlled by gastrin, a hormone (chemical messenger) that's released into the bloodstream. If the stomach can't make acid, blood levels of gastrin rise. High blood levels of gastrin in patients with CAG can cause other cells (ECL cells) in the lining of the stomach to grow and, over the years, to give rise to gastric carcinoids. Gastric carcinoids are usually benign, but they can become malignant. Therefore, patients with CAG and gastric carcinoids have the inside of their stomach checked regularly, by gastroscopy, to see if the gastric carcinoids need removing surgically. A gastroscope is a thin (1 cm), flexible tube at end of which is a mini video camera, which enables the user to inspect the lining of the stomach and a 'snare' to take samples of tissue (biopsies). YF476 (netazepide) is a gastrin receptor antagonist (blocks the effects of gastrin), so it's a potential new medical treatment for gastric carcinoids in patients with CAG. Up to 10 of these patients will take YF476 daily for up to 12 weeks. They'll make up to seven outpatient visits for tests, including checks on the safety of YF476 and up to four gastroscopies. At each gastroscopy, the gastric carcinoids will be measured and biopsies taken for laboratory tests. Patients will take up to 24 weeks to finish the study.

They'll make several outpatient visits for tests, including checks on the safety of YF476. At some of the visits, they'll have a gastroscopy. At each gastroscopy, the gastric carcinoids will be measured and biopsies taken for laboratory tests.
