Who cannot join

• 1) Patients who have received any treatment related to the CD70 target within 3 years; 2) Patients who have received any experimental drug treatment or used experimental devices within 28 days before CAR-T administration; 3) Patients who have received any systemic anti-tumor treatment within 28 days or 5 half-lives (whichever is longer) before CAR-T administration, including systemic chemotherapy, immunotherapy, hormone therapy (excluding glucocorticoids), targeted therapy, systemic immunomodulators (including but not limited to interferon, interleukin 2 and tumor necrosis factor), and received Chinese herbal medicine or Chinese patent medicine with anti-tumor effects within 14 days before CAR-T administration; 4) Patients who have received radiotherapy within three months before administration; 5) Patients who have received other non-CD70 target cell therapy products within two months before administration; 6) Patients who have received other cell therapy products in the past need to undergo RCL testing during the screening period, and patients with positive results in any test; 7) Patients who have received therapeutic doses of glucocorticoids within 14 days before CAR-T administration (however, physiological replacement doses of glucocorticoids are allowed, such as 10 mg/day prednisone or equivalent); 8) Patients who received oral or intravenous anticoagulation within 7 days before CAR-T cell administration; 9) Patients with other malignant tumors previously or concurrently, with the following exceptions: Carcinoma in situ that has been cured and has no signs of recurrence for at least 3 years before the study; The primary malignant tumor has been completely resected and in complete remission for ≥5 years. 10) History of allogeneic organ transplantation or allogeneic hematopoietic stem cell transplantation; 11) Those with immunodeficiency or autoimmune diseases, or those who need to use immunosuppressants; 12) Those who have received live vaccine immunization within 14 days before screening, or those who need to receive live vaccine immunization during the study; 13) Severe or uncontrollable systemic disease or any unstable systemic disease, including but not limited to uncontrolled hypertension, uncontrolled hyperglycemia, hepatic and renal dysfunction or metabolic diseases, central nervous system diseases, etc.; 14) Known severe cardiovascular disease, congenital long QT syndrome, torsades de pointes, myocardial infarction in the past 6 months, or arterial thrombosis, or unstable angina, or congestive heart failure of grade 3 or above (including grade 3) according to the New York Heart Association (NYHA) classification (see Appendix 3), or left ventricular ejection fraction (LVEF) <50%, QTc interval >450 ms for men and >470 ms for women ms; 15) Any one or both of the test results of Treponema pallidum antibody or human immunodeficiency virus (HIV) antibody are positive, cytomegalovirus (CMV) antibody IgM test is positive and CMV DNA titer is more than 2 times higher than the upper limit of normal value; Epstein-Barr virus antibody IgM test is positive and EBV DNA titer is more than 2 times higher than the upper limit of normal value; Hepatitis C virus antibody is positive and hepatitis C virus (HCV) RNA titer is more than 2 times higher than the upper limit of normal value, or active hepatitis B patients (defined as HBsAg positive and peripheral blood HBV DNA titer is more than 2 times higher than the upper limit of normal value); 16) Pregnant or lactating women; The researchers believe that the subjects have other conditions that may affect compliance or are not suitable for participating in this study.
