New CAR-T therapy targets Hard-to-Treat lymphoma

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Willing to participate in this clinical study and sign an informed consent form; 2. Age ≥ 18 years old; 3. Estimated survival time ≥ 3 months; 4. 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; 5. 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); 6. Relapsed or refractory diseases; 7. Subjects who must receive adequate prior therapy; 8. Absence of invasion of central nervous system (CNS) lymphoma by cranial magnetic resonance imaging (MRI); 9. Hematological parameters meeting the requirements; 10. Blood biochemistry meeting the requirements; 11. LVEF ≥ 55%; 12. No severe pulmonary disorders; 13. Toxic reactions induced by prior anti-lymphoma therapy must be stable and resolved to grade ≤ 1; 14. Eastern Cooperative Oncology Group (ECOG) performance status score of 0-1; 15. Patients with physical conditions for apheresis of peripheral blood; 16 . Willing to abide by the rules formulated in the study protocol. Exclusion Criteria: 1. Pregnant or lactating women; 2. Subjects who previously received allogeneic cell therapies, including allogeneic stem cell transplant; 3. Subjects who previously received anti-CD19 targeted therapy, except those who receive BRL-201 and are eligible to receive reinfusion in this study; 4. Prior treatment with any CAR-T cell product or other genetically modified T cell therapies; 5. History of Richter's transformation of chronic lymphocytic leukemia (CLL); 6. 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; 7. 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; 8. Severe mental disorders; history of CNS disorders (e.g., epileptic seizure, cerebrovascular ischemia/hemorrhage, dementia, cerebellar diseases, or any CNS-involved autoimmune disorders); 9. 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; 10. Primary immunodeficiency; 11. History of other malignancies; 12. 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; 13. History of deep venous thrombosis or pulmonary embolism within 6 months before enrollment; 14. 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; 15. 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; 16. 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; 17. Conditions (e.g., intestinal obstruction or vascular compression) requiring emergency treatment due to tumor masses; 18. History of severe immediate hypersensitivity to any drug to be used in this study; 19. Vaccination of live vaccines, excluding corona virus disease 2019 (COVID-19) vaccines, within ≤ 6 weeks before the start of the pretreatment regimen; 20. Any circumstances that possibly increase the risk of subjects or interfere with the study results as judged by the investigator.
