Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 1. Subjects voluntarily participate in clinical research and sign informed consent.
• 2. Subjects with CD19-negative relapsed or refractory B-cell lymphoma: a) failure to achieve CR after 6 cycles, or PR after 3 cycles, of first-line therapy, or achieve CR after first-line therapy but relapse within 12 months; b) achieve CR after systemic treatment, but are refractory or relapsed, and no plan to transplant, or prepare for transplantation but cannot meet transplantation criteria after second-line therapy; c) not achieve CR after at least two courses of second-line treatment (including autologous stem cell transplantation).
• 3. Expected survival ≥ 3 months.
• 4. BAFF-R expression are detected on tumor cells of subjects by flow cytometry or immunohistochemistry.
• 5. ECOG score ≤ 2.
• 6. Subjects with adequate organ functions prior to enrollment, meet the following laboratory values:
• Renal function: serum creatinine ≤ 1.5 × ULN or estimated glomerular filtration rate (eGFR) ≥ 60 mL/min/1.73 m²
• Hepatic function: Serum alanine aminotransferase (ALT) ≤ 5 × age-specific ULN and total bilirubin ≤ 2.0 mg/dL, except in subjects with Gilbert-Meulengracht syndrome. If total bilirubin ≤ 3.0 × ULN and direct bilirubin ≤ 1.5 × ULN, subjects with Gilbert-Meulengracht syndrome are included.
• Pulmonary reserve: ≤ Grade 1 dyspnea and oxygen saturation >95% on room air.
• 7. Stable hemodynamics and left ventricular ejection fraction (LVEF) ≥ 45 % assessed by echocardiography or multi-gated radionuclide angiography (MUGA).
• 8. Adequate bone-marrow reserve without blood transfusion as defined by:
• Absolute neutrophil count (ANC) ≥ 1 x 10\^9/L.
• Absolute lymphocyte count (ALC) ≥ 0.1 x 10\^9/L.
• Platelets ≥ 50 x 10\^9/L.
• Hemoglobin >80g/L.
• 9. In the investigator's judgment, subjects' general condition and all biochemical values are either normal or sufficiently compensated to receive lymphodepletion and CAR-T cell therapy.

You may not qualify if…

• 1. Women who are pregnant or breastfeeding, or planned pregnancy within 6 months.
• 2. Infectious disease(HIV, Active Tuberculosis ect.).
• 3. Active infection: hepatitis B, hepatitis C.
• 4. Abnormal vital signs or refuse to receive examination.
• 5. Subjects with psychiatric or psychological disorders are unable to complete treatment or efficacy assessment.
• 6. History of severe hypersensitivity or known hypersensitivity to IL-2.
• 7. Systemic or local severe infection requiring antimicrobial therapy.
• 8. Significant dysfunction of vital organs (heart, lung, brain, kidney, etc.), or in the investigator's judgment, subjects are unable to be enrolled with any other condition.
