Renal function: Serum creatinine ≤1.5×ULN (if \>1.5×ULN, creatinine clearance must be ≥50 mL/min). Coagulation: INR ≤1.5×ULN and APTT ≤1.5×ULN; patients on anticoagulation may be included if INR ≤2.5×ULN. Oxygenation: Oxygen saturation \>92% on room air. 7. Non-hematologic toxicities from prior therapies (except disease-related) have resolved to ≤grade 1 before enrollment (excluding alopecia and ≤grade 2 neurotoxicity from chemotherapy). 8. Women of childbearing potential must have a negative serum pregnancy test within 7 days prior to ZZSW-01 infusion. All fertile male and female participants must agree to use effective contraception during the study and for at least 6 months after the last dose. (Definition of women of childbearing potential and contraceptive methods are detailed in Appendix 1.) 9. Ability and willingness to provide written informed consent and to comply with study procedures, follow-up assessments, and treatment. Exclusion Criteria Participants meeting any of the following conditions will be excluded from this study: 1. Patients with CNS involvement of B-cell malignancies confirmed by lumbar puncture and/or MRI with CNS-related symptoms. 2. Patients with isolated extramedullary relapse of B-ALL. 3. Patients with severe hereditary diseases or congenital hematopoietic dysfunction. 4. Patients with Burkitt's lymphoma/leukemia or blast phase chronic myeloid leukemia (p210 BCR-ABL+). 5.

Receipt of chemotherapy within 2 weeks prior to ZZSW-01 infusion (except intrathecal chemotherapy for prevention of CNS leukemia, which must be stopped ≥1 week prior to infusion). 7. Prior systemic immune checkpoint inhibitor therapy (e.g., anti-PD-1/PD-L1 mAbs) within fewer than 3 half-lives before ZZSW-01 infusion; or other systemic antitumor therapy within fewer than 2 weeks or 5 half-lives (whichever is shorter) before infusion. 8. Use of systemic therapeutic corticosteroids within 72 hours prior to ZZSW-01 infusion (physiologic replacement doses are allowed, e.g., prednisone \<10 mg/day or equivalent). 9. Receipt of targeted therapies or antibody drugs (including BiTEs, antibody-drug conjugates) within 2 weeks, or cytotoxic therapy within 1 week prior to ZZSW-01 infusion. 10. Autologous stem cell transplantation (ASCT) within 6 weeks prior to ZZSW-01 infusion. 11. Any prior allogeneic hematopoietic stem cell transplantation (allo-HSCT). 12. Known history of the following diseases: 1. . Systemic vasculitis (e.g., Wegener's granulomatosis, polyarteritis nodosa) 2. Systemic lupus erythematosus (SLE) 3. . Active or uncontrolled autoimmune diseases (e.g., Crohn's disease, rheumatoid arthritis, autoimmune hemolytic anemia) 4. .
