Secondary Outcome Measures	Measure Description	Time Frame
Objective response rate (ORR)	ORR, defined as the proportion of participants with a complete response or partial response, as determined by the investigator according to RECIST v1.1	Up to 24 weeks after CAR-T cell infusion
Disease Control Rate（DCR）	DCR,defined as the number of cases in which response are achieved from the start of cell infusion/the total number of evaluable cases (%).	Up to 24 weeks after CAR-T cell infusion
Progression-free survival (PFS)	PFS, defined as the time from CAR-T cell infusion to the first occurrence of disease progression or death from any cause (whichever occurs first) , as determined by the investigator according to RECIST v1.1	Up to 24 weeks after CAR-T cell infusion
Overall survival (OS)	OS , defined as the time from CAR-T cell infusion to death from any cause	Up to 24 weeks after CAR-T cell infusion
Persistence of CAR-T cells (cell counts and cell percentage in peripheral blood)	The persistence over time of CAR T cells in the peripheral blood as determined by flow cytometry and qPCR.	Up to 24 weeks after CAR-T cell infusion

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person’s general health condition or prior treatments.

Ages Eligible for Study:
ALL

Sexes Eligible for Study:
18 Years

Accepts Healthy Volunteers:

Aged 18 to 75 years, either sex;
Patients with pathologically diagnosed advanced gastric/ gastroesophageal junction adenocarcinoma who have failed second-line treatment at least; or patients with pathologically diagnosed advanced pancreatic cancer who have failed first-line treatment at least;
Tumor tissue samples were positive for CLDN18.2 IHC staining(≥+，≥10%);
Estimated life expectancy >12 weeks;
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1;
Women of childbearing age who had a negative blood pregnancy test before the start of the trial and agreed to take effective contraceptive measures during the trial period until the last follow-up; male subjects with fertility partners agreed to take effective contraceptive measures during the trial period until the last follow-up;
Adequate organ function;
Adequate vascular access for leukapheresis procedure;
Volunteer to participate in this trial and sign on the informed consent.

Patients have brain metastasis；
Patients with a history of organ transplantation or awaiting organ transplantation;
The side effects caused by the previous treatment of the subjects did not return to CTCAE ≤1; other tolerable events determined by investigator;
There is a large amount of serous effusion that cannot be controlled by treatment (such as pleural effusion, peritoneal effusion and pericardial effusion);
History of autoimmune disease (eg Crohn's disease, rheumatoid arthritis, systemic lupus) within the last 2 years;
Presence of acute or chronic graft-versus-host disease (GVHD);
Use prohibited drugs or treatments within a specified period of time before cell collection；
History or presence of CNS disorder, such as epilepsy, epileptic seizures, cerebrovascular disease (ischemia / hemorrhage / cerebral infarction), brain edema, reversible posterior white matter encephalopathy, paralysis, aphasia, stroke, severe brain injury, dementia, Parkinson's disease, cerebellar disease, cerebral organic syndrome or mental disease;
Chronic or active infections requiring systemic treatment, and a history of symptomatic viral infection that has not been completely cured；
Live vaccine received within 6 weeks before the start of screening;
Cardiac dysfunction includes: long QTc syndrome or QTc interval > 480 MS; Complete left bundle branch block, grade II / III atrioventricular block; Serious and uncontrolled arrhythmias requiring drug treatment; A history of chronic congestive heart failure with NYHA ≥ 3, and the cardiac ejection fraction was less than 50% within 6 months before screening; Cardiac valvular disease with CTC AE ≥ 3; Myocardial infarction, cardiac angioplasty or stenting, unstable angina pectoris, history of severe pericardial disease or other clinically significant heart diseases within 6 months before screening;
