Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Primary objectives:
\- To evaluate the safety and tolerance of single infusion of BZ019 in adult patients with relapsed or refractory large B-cell lymphoma, and to determine the maximum tolerable dose (MTD) and phase II recommended dose.
Secondary objectives：
* To evaluate the pharmacokinetics and survival of BZ019 in the peripheral blood of adult patients with relapsed or refractory large B-cell lymphoma;
* To evaluate the Pharmacodynamic characteristics of BZ019 in adult patients with relapsed or refractory large B-cell lymphoma;
* Objective response rate (ORR), Overall survival, progression free survival, event free survival, and tumor progression time were used to evaluate the antitumor efficacy of BZ019 in the treatment of relapsed or refractory large B-cell lymphoma.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
BZ019
The subjects are enrolled into 2 dose-escalation cohorts, include 3x10\^6/kg、6x10\^6/kg, and dose-expansion cohorts, maybe 8x10\^6/kg、10x10\^6/kg.
BZ019
A treatment program will include lymphodepleting chemotherapy with fludarabine and cyclophosphamide (flu/cy) followed by single-dose of BZ019 administered intravenously (IV).

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Age ≥ 18 years subjects with Relapsed or refractory large B-cell lymphoma, only DLBCL non-specific type, primary mediastinal large B-cell lymphoma, follicular lymphoma transformed large B-cell lymphoma, advanced B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangement, advanced B-cell lymphoma non-specific type. The definition of refractory is as follows:
* no response to the last treatment, including:The best response to the latest treatment is disease progression (PD), or the best response to the latest treatment plan is disease stability (SD) and the maintenance time is not more than 6 months after the last administration;
* or not suitable for autologous hematopoietic stem cell transplantation (ASCT), or ASCT refractory, including: disease progression after ASCT or recurrence within ≤ 12 months (recurrence must be confirmed by biopsy), or if receiving remedial treatment after ASCT, the subject must have no reaction or recurrence after the last treatment.
* Subjects must be accepted adequate treatment before and have received at least 2 lines of treatment or relapse or progress after autologous hematopoietic stem cell transplantation, and the treatment history at least include:
* Treatment by CD20 monoclonal antibody (Rituximab) except for CD20 negative;
* a chemotherapy regimen containing anthracyclines.
* According to the preliminary evaluation, staging and response evaluation recommendations for Hodgkin and non Hodgkin's lymphoma (2014 Edition), at least one measurable lesion was found in the screening period.
* Life expectancy ≥12 weeks.
* Baseline Eastern Cooperative Oncology Group (ECOG) score is 0 or 1 .
* Adequate organ function:
* Renal function defined as:A serum creatinine of ≤1.5 x ULN or Estimated Glomerular Filtration Rate (eGFR) ≥ 60 mL/min/1.73 m\^2;
* Liver function defined as:Alanine Aminotransferase (ALT) ≤ 5 x ULN；Bilirubin ≤ 2.0 mg/dl with the exception of patients with Gilbert-Meulengracht syndrome; patients with Gilbert-Meulengracht syndrome may be included if their total bilirubin is ≤ 3.0 x ULN and direct bilirubin ≤ 1.5 x ULN;
* Must have a minimum level of pulmonary reserve defined as ≤ Grade 1 dyspnea and pulse oxygenation \> 91% on room air.
* Hemodynamically stable and Left Ventricle Ejection Fraction (LVEF) ≥ 50%, confirmed by echocardiogram or Multigated Radionuclide Angiography (MUGA).
* No blood transfusion within 1 week before signing the informed consent, sufficient bone marrow reserve is available, which is defined as:
* Absolute neutrophil count (ANC) \> 1000/μl;
* Absolute lymphocyte count (ALC) ≥ 500/μl;
* Platelets ≥ 50000/μl;
* Hemoglobin \> 8.0 g/dl, for patients with bone marrow invasion, hemoglobin \> 6.0 g/dl can be considered into the group.
* Must have an apheresis product of non-mobilized cells accepted for manufacturing.
* If the patient uses the following drugs, the following conditions should be met:
* glucocorticoids: The treatment dose of glucocorticoids must be stopped 72 hours before BZ019 infusion. However, glucocorticoids of physiological alternative dose are allowed: prednisone or its equivalent ≤ 15 mg / day;
* Immunosuppression: Any immunosuppressive medication must be stopped ≥ 4 weeks prior to enrollment;
* Antiproliferative therapies other than lymphodepleting chemotherapy within two weeks of infusion
* Antibody use including anti-CD20 therapy within 4 weeks prior to infusion or 5 half-lives of the respected antibody, whichever is longer
* CNS disease prophylaxis must be stopped \> 1 week prior to BZ019 infusion (e.g. intrathecal methotrexate)
* Women of child-bearing age and all male subjects must agree to use effective contraceptive methods until BZ019 are no longer present in the body (detected by PCR).
Exclusion Criteria
* Patients who have previously received any adoptive T cell therapy or gene therapy products, including CAR-T therapy;
* Active Central Nervous System (CNS) involvement by malignancy or secondary CNS involvement
* History or presence of clinically relevant CNS pathology such as epilepsy, seizure, paresis, aphasia, stroke, severe brain injuries, dementia, Parkinson's disease, cerebellar disease, organic brain syndrome, or self-immune disease with CNS involvement.
* Prior allogeneic HSCT.
* Chemotherapy other than lymphodepleting chemotherapy within 2 weeks of infusion.
