Inclusion
Inclusion Criteria
- Patients must meet all of the following criteria to be eligible for the study:
Voluntarily participate in the clinical study. The individual or the legalguardian fully understands the study, sign the informed consent form (ICF), andis willing and able to follow and complete all trial procedures.
Age ≥ 14 years and < 70 years.
Subjects with refractory or relapsed disease after current standard treatments (including allogeneic or autologous hematopoietic stem cell transplantation)who are not suitable for other treatment options, such as a second stem celltransplant. The definitions of relapsed/refractory lymphoma include one of thefollowing situations:
No response to first-line treatment (primary refractory disease, excludingparticipants intolerant to first-line treatments).
- Disease progression (PD) as assessed after first-line treatment.
- Best efficacy of first-line treatment (e.g., 4 cycles of RCHOP) asstable disease (SD), with the duration of SD not exceeding 6 monthsafter the last dose.
- No response to second-line or more treatments.
- PD being the best response to the most recent treatment.
- Best efficacy of the last line of treatment as SD after at least 2cycles, with the duration of SD not exceeding 6 months after the lastdose.
- Refractory after autologous stem cell transplant (ASCT).
- Disease progression or relapse ≤ 12 months post-ASCT (relapsedpatients must have biopsy-proven relapse).
- If salvage treatment is administered after ASCT, the subjects mustnot have had a response or relapse after the last line of treatment.
- Relapsed or refractory disease after two or more lines of systemictreatment.
Lymphoma patients must have target antigens meeting the following criteria:
CD20/CD30 double-positive expressing lymphoma.
Relapse after receiving anti-CD19-CAR-T cell therapy, with CD20 positivelymphoma.
CD20 positive lymphoma that has not previously received anti-CD19-CAR-Tcell therapy.
CD30 positive Hodgkin lymphoma.
Subtypes of lymphoma included for enrollment are as follows:
DLBCL-NOS (diffuse large B-cell Lymphoma, not otherwise specified)
Primary mediastinal B-cell lymphoma (PMBCL)
Transformed follicular lymphoma (TFL), previously treated for follicularlymphoma and then transformed to refractory DLBCL
Mantle cell lymphoma
High-grade B-cell lymphoma
Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL)
Hodgkin lymphoma (HL)
ECOG performance status ≤ 2.
Expected survival of at least 12 weeks.
Adequate venous access (for apheresis) and no other contraindications for bloodcell separation.
Laboratory tests during screening must meet the following requirements, and thehematological assessment must not have received cell growth factors within 7days (long-acting colony-stimulating factors (G-CSF/PEG-CSF) require a 2-weekinterval) or platelet transfusions:
Absolute neutrophil count ≥ 1.0×10^9/L.
Hemoglobin ≥ 60 g/L (without red blood cell transfusion in the last 7days).
Platelets ≥ 50×10^9/L (unrestricted for CLL indications).
Total bilirubin ≤ 1.5× the upper limit of normal (ULN); or total bilirubin ≤ 3× ULN when the tumor invades liver tissue.
Aspartate transaminase (AST), alanine transaminase (ALT) ≤ 2.5×ULN, withAST/ALT ≤ 5×ULN when the tumor invades liver tissue.
Creatinine < 1.5× ULN and estimated creatinine clearance ≥ 60 mL/min.
Ejection fraction ≥ 45%, with echocardiogram (ECHO) confirming no pericardialeffusion (excluding small or physiological amounts), and electrocardiogramresults with no clinical significance.
Baseline oxygen saturation > 92% without supplemental oxygen.
Women of childbearing potential must have a negative serum or urine pregnancytest result (women who have undergone surgical sterilization or have beenpostmenopausal for at least 2 years are not considered of childbearingpotential).
Exclusion
Exclusion Criteria:
- Subjects are not eligible to participate in this study if they meet any of thefollowing criteria:
MRI of the brain shows evidence of central nervous system lymphoma; activeprimary central nervous system DLBL, unless central nervous system involvementhas been effectively treated (i.e., participant is asymptomatic), and there hasbeen more than a 4-week gap since local treatment.

History of or concurrent diagnosis of malignancies other than CD19+malignancies.
Clinically significant heart disease or arrhythmias that cannot be controlledwith medication.
Presence or suspicion of fungal, bacterial, viral, or other infections that areuncontrolled or require intravenous antibiotics for treatment; uncomplicatedurinary tract infections and uncomplicated bacterial pharyngitis are allowed.
Positive for hepatitis B (HBsAg positive and HBV DNA >1000 copies/mL) andhepatitis C (positive for HCV antibodies); syphilis or human immunodeficiencyvirus (HIV) infection.
Presence of any indwelling catheter or drainage tube (such as percutaneousnephrostomy, indwelling Foley catheter, bile drainage tube, orpleural/peritoneal/pericardial catheter); use of specialized central venousaccess devices like Port-A-Cath® or Hickman® catheters is allowed.
History of using any of the following medications:
Lenalidomide within 1 day before the apheresis.
Idelalisib (oral PI3Kδ inhibitor) within 2 days before the apheresis.
Short-acting targeted therapy (like tyrosine kinase inhibitors) within 72hours before the apheresis.
Venetoclax (BCL-2 inhibitor) within 4 days before the apheresis.
Long-acting growth factors (like pegylated filgrastim) within 14 daysbefore the apheresis, or short-acting growth factors or mobilizationagents (like G-CSF/filgrastim, plerixafor) within 5 days before theapheresis.

Any medical activities that could interfere with the safety or efficacyevaluation of the study treatment.
In the judgment of the investigator, subjects are unlikely to complete allrequired study visits or procedures (including follow-ups) or to comply withthe study participation requirements.
