Inclusion 18

  • Minimum age: 18 years
  • Study condition: Non-hodgkin Lymphoma,B Cell
  • Willing to participate in this clinical study and sign an informed consent form;
  • Age ≥ 18 years old;
  • Estimated survival time ≥ 3 months;
  • Presence of at least one measurable lesion as assessed according to Lugano Classification 2014 for response assessment in lymphomas (i.e., the cross-sectional images obtained by CT show that the long diameter of lymph node lesions is \> 15 mm or the long diameter of extranodal lesions is \> 10 mm, and FDG-PET scan results are positive).
  • Lesions, for which radiotherapy was provided, can be regarded as measurable lesions only if there is an unequivocal progression after radiotherapy;
  • Histopathologically confirmed aggressive B-NHL; positive expression of CD19 in tumors detected by immunohistochemistry or flow cytometry; pathological types of B-NHL (according to WHO Lymphoma Classification 2016);
  • Relapsed or refractory diseases;
  • Subjects who must receive adequate prior therapy;
  • Absence of invasion of central nervous system (CNS) lymphoma by cranial magnetic resonance imaging (MRI);
  • Hematological parameters meeting the requirements;
  • Blood biochemistry meeting the requirements;
  • LVEF ≥ 55%;
  • No severe pulmonary disorders;
  • Toxic reactions induced by prior anti-lymphoma therapy must be stable and resolved to grade ≤ 1;
  • Eastern Cooperative Oncology Group (ECOG) performance status score of 0-1;
  • Patients with physical conditions for apheresis of peripheral blood; 16 . Willing to abide by the rules formulated in the study protocol.

Exclusion 20

  • Pregnant or lactating women;
  • Subjects who previously received allogeneic cell therapies, including allogeneic stem cell transplant;
  • Subjects who previously received anti-CD19 targeted therapy, except those who receive BRL-201 and are eligible to receive reinfusion in this study;
  • Prior treatment with any CAR-T cell product or other genetically modified T cell therapies;
  • History of Richter's transformation of chronic lymphocytic leukemia (CLL);
  • Presence of uncontrollable fungal, bacterial, viral, or other infections requiring systemic therapy. Patients can be enrolled if the simple urinary tract infection or pharyngitis responds to treatment;
  • Subjects with positive hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) and peripheral blood HBV DNA titer higher than the upper limit of detection; hepatitis C virus (HCV) antibody positive and peripheral blood HCV RNA positive; human immunodeficiency virus (HIV) antibody positive; syphilis test positive;
  • Severe mental disorders; history of CNS disorders (e.g., epileptic seizure, cerebrovascular ischemia/hemorrhage, dementia, cerebellar diseases, or any CNS-involved autoimmune disorders);
  • Active autoimmune disorders requiring immunotherapy, including but not limited to end organ damages caused by autoimmune disorders (e.g., Crohn's disease, rheumatoid arthritis, and systemic lupus erythematosus) in the past 2 years, or requiring systemic application of immunosuppressive drugs or other drugs for systemic control of diseases;
  • Primary immunodeficiency;
  • History of other malignancies;
  • Patients with severe cardiovascular disorders, including but not limited to those with lymphoma infiltration in the cardiac atrium or ventricles and those with a history of myocardial infarction, cardioangioplasty or stent implantation, unstable angina, or other clinically significant heart diseases within 12 months before enrollment;
  • History of deep venous thrombosis or pulmonary embolism within 6 months before enrollment;
  • Patients who are receiving oral anticoagulant therapy; prothrombin time (PT), activated partial thromboplastin time (APTT), or international normalized ratio (INR) \> 1.5 × ULN without anticoagulant therapy;
  • Presence of any indwelling tube or catheter (e.g., tube or catheter for percutaneous nephrostomy, indwelling catheter, or catheter in pleural cavity/peritoneal cavity/pericardium). Dedicated central venous access catheters (e.g., Port-a-Cath or Hickman catheter) are permitted;
  • Lymphoma cells detected in cerebrospinal fluid, presence of brain metastases, history of CNS lymphoma, or history of lymphoma cells detected in cerebrospinal fluid or brain metastases;
  • Conditions (e.g., intestinal obstruction or vascular compression) requiring emergency treatment due to tumor masses;
  • History of severe immediate hypersensitivity to any drug to be used in this study;
  • Vaccination of live vaccines, excluding corona virus disease 2019 (COVID-19) vaccines, within ≤ 6 weeks before the start of the pretreatment regimen;
  • Any circumstances that possibly increase the risk of subjects or interfere with the study results as judged by the investigator.
