Brief summary: This single-arm, multicenter Phase 2 trial will treat the patients who have relapsed or refractory stomach cancer with an infusion of the patient's own T cells that have been genetically modified to express a chimeric antigen receptor(CAR) that will bind to tumor cells that express the EPCAM protein on the cell surface.The study will determine if these modified T cells help the body's immune system eliminate tumor cells.The trial will also study the safety of treatment with CAR-T, how long CAR-T cells stay in the patient's body and the impact of this treatment on survival.

Detailed description: This is a single-arm, multicenter Phase 2 study to evaluate the efficacy and safety of the CAR-T for Stomach Cancer. The study will be conducted using a phaseⅠ /Ⅱ design.The study will have the following sequential phases: Part A(screening leukapheresis, cell product preparation, and cytoreductive chemotherapy) and Part B(treatment and follow-up). The follow-up period for each participant is approximately 35 months after the final CAR-T infusion.The total duration of the study is expected to be approximately 3 years. A total of 19 patients may be enrolled over a period of 3 years.

Eligibility criteria: Inclusion Criteria:
