About this study

Neoadjuvant radiotherapy plus Tegafur, Oxaliplatin and Iparomlimab and Tuvonralimab in Resectable Gastric and GE-junction Cancer : A Randomized, Two-arm, Prospective Trial (TRIUNITE-05)

Read the detailed description

TRIUNITE-05 is a randomized, two-arm, uncontrolled, prospective study to evaluate the efficacy and safety of neoadjuvant radiotherapy combined with immunochemotherapy for locally advanced G/GEJ adenocarcinoma. This study will include subjects with locally progressive G/GEJ adenocarcinoma, patients in Group A will be treated with radiotherapy (30Gy/10f) followed by sequential SOX regimen in combination with Iparomlimab and Tuvonralimab (5 mg/kg, i.v.) for 6 cycles of induction therapy, with full evaluation and surgery 4-6 weeks after the end of the treatment; patients in group B will be treated with SOX regimen in combination with Iparomlimab and Tuvonralimab for 3 cycles of induction therapy followed by sequential radiotherapy ( 30Gy/10f) followed by 3 cycles of sequential SOX regimen combined with Iparomlimab and Tuvonralimab (5 mg/kg, i.v.), with full evaluation and surgery 4~6 weeks after the end of treatment. For those who were assessed to be inoperable after neoadjuvant therapy, the original regimen of immunotherapy in combination with chemotherapy was concurrently administered until progression; if it was ineffective, the regimen was changed to a second-line chemotherapy regimen or other anti-tumor combination therapy regimens were considered as appropriate. Patients were then entered into long-term survival follow-up. During the study period, preoperative and postoperative blood, feces, and pathological tissues of subjects were collected for testing biomarkers to explore the potential benefit population of neoadjuvant therapy. Blood and fresh tissues were subjected to single-cell sequencing, spatial transcriptomic or proteomic analysis, and tissues were subjected to multiplex immunofluorescence assay, in order to further search for potential biomarkers that may be beneficial for the benefit of neoadjuvant therapy in locally advanced gastric cancer.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Iparomlimab and Tuvonralimab, Oxaliplatin and Tegafur in people with Immunotherapy and Gastric Cancer (GC), run by Daping Hospital and the Research Institute of Surgery of the Third Military Medical 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 16 inclusion and 44 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: looking for participants now, as of the sponsor's last update on 10 Sep 2025. 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?

Contact Bin Wang (023-68757743, wb_tmmu@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pathological Complete Response (pCR) (time frame: 8 months). 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 NCT07165847.

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 10 Sep 2025.
