About this study

Official title: PD-1 Antibody Adjuvant Therapy for Patients With MSI-H Advanced Gastric or Gastroesophageal Junction Cancer After Radical Surgery With D2 Dissection: a Phase II Single-center, Three-arm, Randomized Controlled Clinical Trial

Approximately 5% to 10% of gastric cancers have MSI-H/dMMR. According to the results of retrospective analysis of CLASSIC and MAGIC, MSI-H/dMMR was a good prognosis and potential negative predictor of adjuvant chemotherapy for resectable gastric cancer. GC patients with MSI-H/dMMR were relatively insensitive to chemotherapy. The prognosis of these patients receiving routine postoperative adjuvant chemotherapy was worse than that with surgery alone. However, these patients were sensitive to immunotherapy. MSI-H/dMMR is one of the most important biomarkers to predict the efficacy of immunotherapy for GC. In this study, patients with MSI-H locally advanced gastric adenocarcinoma after radical surgery with D2 dissection would be randomly treated with conventional adjuvant chemotherapy, PD-1 monoclonal antibody immunotherapy or follow-up observation. We intend to demonstrate that the prognosis of MSI-H GC patients after D2 radical gastrectomy receiving PD-1 monoclonal antibody immunotherapy would be better than that with standard postoperative adjuvant chemotherapy and follow-up observation.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing SOX, XELOX and PD-1 antibody in people with MSI-H and PD-1 Immunotherapy, run by Fudan University at 1 site in China.

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 10 inclusion and 18 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 11 Aug 2026. 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 China. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

3 year Disease Free Survival (time frame: 3 years). 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 NCT05468138, which also lists 5 linked publications.

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 11 Aug 2026.
