Summary: This study is a open-label, dose-escalating + dose-expansion clinical study, aiming to evaluate the safety and efficacy of CEA-targeted CART cell preparations, and to reliminarily observe the study drug in CEA-positive advanced malignant tumors. The pharmacokinetic characteristics of CART cell preparations for the treatment of patients with CEA-positive advanced malignancies were obtained and the recommended dose and infusion schedule.

Detailed description: According to the infusion ways, it is divided into two subgroups: intravenous infusion and intraperitoneal injection. Each subgroup includes a dose exploration stage and a dose expansion stage. 3 patients were explored, starting from the low-dose group, and in the dose expansion phase, the safety and efficacy were further verified according to the safe recommended dose obtained in the dose exploration phase.

Criteria for eligibility:
Criteria:
Inclusion Criteria: 1. Age ≥18 years old, male or female; 2. Advanced, metastatic or recurrent malignant tumors diagnosed by histology or pathology, mainly colorectal cancer, esophageal cancer, gastric cancer, and pancreatic cancer; 3.

Cardiac function: echocardiography showed cardiac ejection fraction ≥50%, and no obvious abnormality was found on electrocardiogram; 3. Renal function: serum creatinine≤2.0×ULN; 4. Liver function: ALT and AST ≤3.0×ULN (for patients with liver tumor infiltration, it can be relaxed to ≤5.0×ULN); 5. Total bilirubin≤3.0×ULN; 6. Oxygen saturation ≥95% in non-oxygen state. 9. Have apheresis or venous blood collection standards, and have no other contraindications for cell collection; 10. Subjects agree to use reliable and effective contraceptive methods for contraception within 1 year after signing the informed consent form to receiving CAR-T cell infusion (excluding rhythm contraception); 11. The patients themselves or their guardians agree to participate in this clinical trial and sign the ICF, indicating that they understand the purpose and procedures of this clinical trial and are willing to participate in the research. Exclusion Criteria: 1. Those who have central nervous system metastasis or meningeal metastasis at the time of screening are judged by the investigator to be unsuitable for inclusion; 2. Participated in other clinical studies within 1 month before screening; 3. vaccinated with live attenuated vaccine within 4 weeks before screening; 4. Received the following anti-tumor treatments before screening: Received chemotherapy, targeted therapy or other experimental drug treatments within 14 days or at least 5 half-lives (whichever is shorter); 5. Active infection or uncontrollable infection requiring systemic treatment; 6. Patients with intestinal obstruction, active gastrointestinal bleeding, or a history of gastrointestinal bleeding within 3 months; 7. There is a large amount of uncontrolled fluid accumulation in the serous cavity; 8. Except for alopecia or peripheral neuropathy, the toxicity of previous anti-tumor therapy has not improved to the baseline level or ≤ grade 1; 9. Suffering from any of the following heart diseases: 1. New York Heart Association (NYHA) stage III or IV congestive heart failure; 2. Myocardial infarction or coronary artery bypass grafting (CABG) within 6 months before enrollment; 3. Clinically significant ventricular arrhythmia, or a history of unexplained syncope (except those caused by vasovagal or dehydration); 4. History of severe non-ischemic cardiomyopathy; 10. Patients with active autoimmune disease, or other patients requiring long-term immunosuppressive therapy; 11.
