- According to the RECIST 1.1 criteria for evaluating the efficacy of solid tumors, there must be at least one measurable lesion as the target lesion for efficacy evaluation. The total diameter of the overall tumor lesion (excluding bone metastases) should be ≤ 100mm, and the diameter of a single tumor lesion should be ≤ 30mm. If the lesion that has received local treatment (radiotherapy, ablation, vascular intervention, etc.) is the only lesion, then there must be clear imaging evidence of disease progression for this lesion.

About this study
Official title: A Single-center, Non-randomized, Open-label Clinical Trial to Evaluate the Safety, Tolerability and Preliminary Efficacy of XH001 Injection Combined With Neoantigen Vaccine-induced Tumor-specific T-cell Injection in Advanced Gastric Cancer.
The goal of this clinical trial is to learn the safety of tumor neoantigen vaccine combined with neoantigen vaccine induced T-cell in treating advanced gastric cancer in adults. It will also learn if the combined treatment works to treat advanced gastric cancer.
The main questions it aims to answer are:
What medical problems do participants have when using the combined treatment? Does tumor neoantigen vaccine combined with neoantigen vaccine induced T-cell eliminate or shrink the tumor, and can it prolong the patient's survival period?

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing XH001 Injection and Tumor vaccine-induced specific T-cell injection in people with Advanced Gastric Cancer, run by Jia Wei 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 6 inclusion and 17 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 25 Feb 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 JIA Wei, MD (0086-025-83304616, jiawei99@nju.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Adverse Event (time frame: 12 months). 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 NCT07298200, 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 25 Feb 2026.
