Mutant KRAS G12V-specific TCR Transduced T Cell Therapy for Advanced Solid Tumor

Inclusion Criteria:

1.Age ≥18 years and ≤75 years. 2.Failure on or intolerance to systemic therapy for unresectable advanced cancer.

3.Patients must have at least one measurable lesion defined by RECIST 1.1. 4.Genotype and tumor antigen screening must meet the following two criteria: 1) HLA-A \* 11:01 positive; 2) KRAS G12V positive 5.ECOG score 0-1 and expected survival time ≥3 months 6.Patients must meet the following criteria at screening and before preconditioning (baseline). If any laboratory test result is abnormal referring to the following criteria, it is acceptable to test one more time within 1week. If the test result is still abnormal, the patient is screen failed:

1. Hematology (no intensive blood transfusion (≥2 times within 1week), platelet transfusion or cell growth factor (except for recombinant erythropoietin) performed within 7days before the test): neutrophils (NE) ≥1.5×109 per liter, lymphocytes (LY) ≥0.5×109per liter (except for before preconditioning), platelets (PLT) ≥75×109per liter and hemoglobin (Hb) ≥8.0 g/dL.
2. Blood chemistry: creatinine clearance ≥mL/min, alanine aminotransferase (ALT) ≤2.5×ULN, aspartate aminotransferase (AST) ≤2.5×ULN, total bilirubin (TB) ≤2×ULN, serum lipase and amylase \<1.5 ULN, alkaline phosphatase (ALP) ≤2.5 ULN; for patients with bone or hepatic metastasis, AST, ALT and ALP \<5ULN.
3. Prothrombin time ≤ULN+4 seconds. 7.Women of childbearing potential must have negative serum pregnancy test result at screening and before preconditioning and agree to use an effective and reliable contraceptive method for at least 1 year after the last study treatment. Te acceptable methods include bilateral tubal ligation/bilateral salpingectomy or bilateral tubal occlusion; any approved oral, injection or implantation of hormone; or barrier contraceptive method: condoms containing spermicidal foam/gel/film/paste /suppositories or occlusive cap (diaphragm or cervical/fornix cap).

8.Voluntarily willing to participate in the study and sign the written informed consent.

9.No systemic anti-tumor therapy received within 2 weeks prior to peripheral blood mononuclear cell (PBMC) collection.

10.Blood oxygen saturation (finger oxygen detection)≥ 95% in a calm and non oxygenated state.

Exclusion Criteria:

1. Pregnant or lactating women.
2. HIV, treponema pallidum or HCV serology is positive.
3. Patients with any uncontrolled active infection, including, but not limited to, active tuberculosis or HBV infection (HBsAg positive or HBV DNA positive).
4. Patients with AEs induced by previous treatment that have not recovered to Common Terminology Criteria for Adverse Events (CTCAE) ≤1, except for alopecia and other tolerable events judged by the investigator or permitted laboratory abnormalities according to the protocol.
5. Patient allergic or intolerant to preconditioning drugs, including, but not limited to, fudarabine and cyclophosphamide or oxaliplatin; allergic to the components of YK0901; penicillin allergy history confrmed by positive skin test; or any severe allergy history-for example, anaphylactic shock.
6. Patients who have a history of organ transplantation or are waiting for organ transplantation.
7. Patients who have undergone major surgery or severe trauma within 4weeks before apheresis .
8. Patients with other serious diseases that may restrict them from participating in this study, such as poorly controlled diabetes (glycosylated hemoglobin HbA1c \>8% undertreatment), poorly controlled hypertension judged by the investigator (blood pressure \>160mmHg/100mmHg), severe cardiac insufficiency (left ventricular ejection fraction \<50%), myocardial infarction or unstable arrhythmia or unstable angina pectoris, pulmonary embolism, chronic obstructive pulmonary disease, interstitial lung disease or clinically significant lung function test abnormalities in the past 6months.
9. Before apheresis and preconditioning, patients who have the following conditions, including, but not limited to: new-onset arrhythmia that cannot be controlled by medications; hypotension that requires the use of vasopressors; or bacterial, fungal or viral infections that require intravenous antibiotic, antiviral or antifungal treatment, and the investigator judged that they are not suitable to continue the experiment. Patients who use antibiotics to prevent infection can continue the study upon the judgment of the investigator
10. Patients who are expected to continue using immunosuppressive therapy during the trial (excluding physiological replacement therapy with glucocorticoids, such as prednisone\<10mg/d or equivalent doses)
11. Patients with central nervous metastases.
12. Patients who have participated in other intervention clinical trials within 2 weeks.
13. Patients with adverse drug addiction or a history of drug abuse.
14. Patient with other malignant tumors within the past 2 years or at the present, except for cervical cancer in situ and basal cell carcinoma of the skin.
15. Patients who are unable or unwilling to comply with the clinical protocol, by the investigator's judgment.
