Clinical Study of the Safety and Efficacy of Allogeneic TCR-enhanced Vδ2 T Cell in Patients With Malignant Tumors.

Inclusion Criteria: * Age 18-75 (inclusive). * Expected survival time ≥ 3 months. * Meets current clinical diagnostic criteria with a confirmed diagnosis of a malignant hematologic tumor or solid tumor, and has failed standard therapy (for solid tumors, at least one evaluable lesion according to RECIST v1.1 is required). * Adequate bone marrow reserve and essentially normal liver and kidney function (laboratory tests must meet the following criteria prior to the first allogeneic TCR-enhanced Vδ2 T cell treatment): * Hematology: White Blood Cell Count (WBC) ≥ 2.5×10⁹/L, Lymphocyte Count (LY) ≥ 0.8×10⁹/L, Hemoglobin (Hb) ≥ 80 g/L, Platelets (PLT) ≥ 75×10⁹/L. * Liver: ALT ≤ 3 × ULN; AST ≤ 3 × ULN; Total Bilirubin ≤ 3.0 × ULN. * Kidney: Serum Creatinine ≤ 1.5 × ULN. * Cardiac: Left Ventricular Ejection Fraction (LVEF) ≥ 50% as measured by echocardiogram. * Pulmonary: Normal oxygen saturation without supplemental oxygen. * Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0-1. * A negative pregnancy test is required for women of childbearing potential. Both male and female subjects must agree to use effective contraception during the treatment period and for 1 year thereafter. * Able to understand the trial requirements and is willing to participate in the clinical study as required. * Voluntarily signs the informed consent form for the clinical trial. Exclusion Criteria: * Known history of allergy, hypersensitivity, intolerance, or contraindication to allogeneic TCR-enhanced Vδ2 T cell or any components of the study drugs (including fludarabine, cyclophosphamide and albumin paclitaxel). * Continuous use of immunosuppressants within 1 month prior to allogeneic TCR-enhanced Vδ2 T cell infusion. * History of cerebrovascular accident or seizure within 6 months prior to signing the informed consent. * Symptomatic brain metastases. * Known psychiatric or substance abuse disorders that would compromise compliance with study requirements. * Positive for Hepatitis B surface antigen (HBsAg) or Hepatitis B core antibody (HBcAb) with detectable Hepatitis B virus (HBV) DNA levels outside the normal reference range; positive for Hepatitis C virus (HCV) antibody with detectable HCV RNA; positive for Human Immunodeficiency Virus (HIV) antibody; positive for syphilis. * Severe cardiac disease, including but not limited to unstable angina, myocardial infarction (within 6 months prior to screening), congestive heart failure (NYHA Class ≥ III), and severe arrhythmia. * Active or uncontrolled infection requiring systemic therapy (except for mild urogenital and upper respiratory tract infections). * Has not recovered from acute toxic effects of prior therapy (i.e., persisting hematological or organ toxicity ≥ Grade 2 related to prior therapy, excluding abnormalities associated with the study disease and its history). * Diagnosed with immunodeficiency. * Active infection requiring systemic treatment. * Female subjects of childbearing potential planning pregnancy within 2 years after cell infusion; or male subjects whose partners are planning pregnancy within 2 years after cell infusion. * Participation in another investigational drug clinical study within 1 month prior to screening. * Last anti-tumor therapy administered less than 5 half-lives of the drug prior to planned allogeneic TCR-enhanced Vδ2 T cell infusion. * Any other condition deemed by the investigator to make the subject unsuitable for participation in this study.
