Abnormal pulmonary function indicated by a ratio of forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) \< 70% in pulmonary function tests. 9. A history of clinically significant central nervous system (CNS) disorders, including but not limited to epilepsy, paresis, aphasia, stroke, severe traumatic brain injury, dementia, Parkinson's disease, cerebellar disease, and organic brain syndrome. 10. Use of the following drugs or treatments: 1.

Chemotherapy: Receipt of salvage chemotherapy within 2 weeks prior to administration of the study drug; 3. GvHD treatment: Receipt of anti-GvHD therapy within 4 weeks prior to administration of the study drug; 4. Allogeneic bone marrow transplantation; 5. Gene therapy; 6. Adoptive cell therapy; 11. Females who are pregnant or breastfeeding. 12. A history of primary immunodeficiency or autoimmune disease, except for the following: * History of hypothyroidism with stable thyroid hormone replacement therapy; * Patients with well-controlled type 1 diabetes mellitus. 13. Patients whose disease or condition renders them unable to understand, participate in, and/or comply with the study protocol. 14. Any other disease that the investigator believes would impair the subject's ability to tolerate protocol treatment or significantly increase the risk of complications. 15. Current or past history of psychoactive substance abuse or dependence. 16. Subjects whose underlying condition, in the investigator's judgment, may increase the risk of receiving the investigational drug or confound the interpretation of toxic reactions and adverse events. 17. Other conditions deemed unsuitable for participation in the study by the investigator. Screening Period 2 Inclusion Criteria 2: The patient's organ function and key test items at this stage should not have significant changes compared with their test results in Screening Period 1. If the patient's test results in Screening Period 2 exceed the following criteria, they should not receive administration of KXV01 Injection until the abnormal items return to the normal range. 1. The patient's KXV01 Injection has been successfully prepared. 2. Expected survival time \> 6 months. 3. ECOG performance status of 0 or 1. 4. Sufficient organ function. 5. Females of childbearing potential have a negative blood pregnancy test within 7 days prior to administration of the study drug (Non-childbearing potential: surgically sterilized or postmenopausal for at least 2 years). In addition, female subjects of childbearing potential must use medically approved contraceptive measures for 12 months after the start of study treatment and have no egg retrieval during this period. 6. Male subjects are willing to use medically approved contraceptive measures from the time of signing the informed consent form until 12 months after the start of study treatment, and will not donate sperm during this period. 7. At least one measurable lesion according to RECIST v1.1 criteria. 8. Toxicities and adverse reactions caused by prior therapy should have resolved to Grade ≤ 1 (except for toxicities considered clinically insignificant, such as chemotherapy-induced alopecia).
