Brief Summary

This is a Phase 1, single-arm, single-center, open-label study to evaluate the safety and effectiveness of NKG2D-based CAR-T cells infusion in the treatment of advanced NKG2DL+ solid tumors.

9. Patients must have measurable lesions as defined by RECIST 1.1;

10. Patients fully understand the test and voluntarily sign the informed consent;

11. Patient agree to use approved contraceptive methods (e.g., birth control pills, barrier devices, iuds, contraindicated drugs) during the study and for at least 12 months after last cell infusion, until no CAR-T cells were detected by two consecutive PCR tests.

Exclusion Criteria

1. Patients had received any gene therapy (including CAR-T cell therapy) or any T cell therapy, Active bacteria or viral or fungal infection and not controlled after anti-infective treatment (positive blood test 72 hours before infusion), Syphilis, Human immunodeficiency virus (HIV), Active hepatitis B (HBV DNA≥500IU/ml) or hepatitis c (anti-HCV positive and HCV RNA higher than the detection limit of analysis method);

2. Patients have an autoimmune disease or organ transplant, require chronic systemic steroid therapy or any other form of immunosuppressive drugs;

3. A history of serious heart or lung disease, including uncontrolled hypertension medication, and any condition that occurred within the past 6 months: congestive heart failure (New York Heart Association functional classification ≥3), cardiac angioplasty and stents, myocardial infarction, unstable angina, or other clinically severe heart disease;

4. Detected clinically relevant central nervous system (CNS) metastases and/or pathologies, such as seizures, cerebral ischemia/bleeding, dementia, cerebellar diseases or autoimmune diseases affecting the CNS;

5. The Patients' history or existing evidence of any condition such as neuroticism, psychosis, immunology, metabolism, and infectious disease, in any treatment, or laboratory abnormalities may confuse the outcome of the study, interfere with the Patients' participation during the study, or not participate in the Patients' best interests with investigator treatment;

6. The Patients have a history of hematologic malignancy or concurrent history of other malignant primary solid tumors, except for: 1) Patients with cervical or breast cancer in situ who have no evidence of disease for more than 3 years after radical treatment; 2) Patients who have successfully received definite resection of tumor in situ and have no evidence of disease for ≥5 years;
