入选标准
- •1.The subject or guardian must provide voluntary informed consent; 2.Heavily pretreated patients with relapsed or refractory T-LBL/ALL who lack effective therapeutic alternatives; 3.At screening, CD7 positivity of tumor cells must be documented by flow cytometry (on bone marrow or peripheral blood samples) and/or by immunohistochemistry (IHC) confirming CD7 expression on an extramedullary lesion biopsy; 4.If malignant cells are detected in the peripheral blood at screening, they must demonstrate a CD4-negative and CD8-negative (double-negative) immunophenotype as assessed by flow cytometry; 5.Male or female subjects, aged 18 to 75 years (inclusive); 6.Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 to 2; 7.Estimated survival time>12 weeks.
排除标准
- •1.Patients with a history of allogeneic hematopoietic stem cell transplantation within the past 6 months are excluded; 2.Active or uncontrolled infection requiring systemic treatment at screening, excluding mild genitourinary and upper respiratory infections； 3.Participation in another clinical trial within 4 weeks prior to signing the informed consent form (ICF), OR the date of ICF signing occurring within 5 half-lives of the last dose from a previous investigational drug trial (whichever timeframe is longer); 4.Patients with previous treatment involving CAR-T cells or other gene-modified cell therapies are excluded; 5.Patients with acute GVHD (aGVHD) or moderate-to-severe chronic GVHD (cGVHD) within 4 weeks prior to screening, or those who have received systemic pharmacologic therapy for GVHD within 4 weeks prior to infusion; 6.Patients who have received extensive radiotherapy within 4 weeks prior to ICF signing, with the exception of non-target lesion radiotherapy administered for symptomatic palliation that may be permitted during the study period; 7.Women who are pregnant or lactating; 8.Any condition that, in the judgment of the Investigator, could increase the subject's risk or compromise the interpretation of the trial results.
