About this study

Official title: Effect of Helicobacter Pylori Eradication on Glandular Atrophy and Metachronous Cancer in Patients Undergoing Endoscopic Mucosal Resection for Gastric Cancer

This study evaluates whether Helicobacter pylori eradication improves precancerous lesions including glandular atrophy and intestinal metaplasia as well as metachronous cancers or dysplasias after endoscopic mucosal resection for gastric cancer.

Read the detailed description

Helicobacter pylori is a primary etiological agent leading to chronic gastritis and peptic ulcer. The organism is also associated with gastric cancer in epidemiological studies. However detailed mechanism of carcinogenesis remains unknown. Histolopathological studies indicate that chronic H. pylori infection progresses over decades through stages of chronic gastritis, atrophy, intestinal metaplasia, dysplasia and cancer. Gastric atrophy and intestinal metaplasia are considered as precancerous lesions, but whether H. pylori eradication improves these lesions and prevents metachronous gastric cancer is controversial. And the issue has not been evaluated in gastric cancer patients. However, despite the conflicting evidences from two open labelled randomized controlled trials, current guidelines from various regions recommend H. pylori eradication treatment in patients who were treated for gastric cancer by surgically or endoscopically. Thus, it is important to evaluate whether H. pylori eradication can improve known precancerous lesion, i.e. glandular atrophy and intestinal metaplasia in gastric cancer patients. Such histological improvement can eventually reduce secondary gastric cancer development and provide evidence for current guidelines.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 7 day H.pylori eradication Omeprazole or Rabeprazole, Clarithromycin, Amoxicillin in people with Helicobacter Pylori Infection and Early Gastric Cancer, run by National Cancer Center, Korea at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 9 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Improvement (histological) of glandular atrophy (time frame: 3 years after enrollment). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02407119, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Nov 2023.
