Criteria

Inclusion Criteria:

• Patient who understands and speaks one of the country official languages and signed Informed Consent Form

• Histologically proven relapsed or refractory aggressive B-cell non-Hodgkin lymphoma (B-NHL) of the following histology at relapse: diffuse large B-cell lymphoma (DLBCL), high-grade B-cell lymphoma (HGBL), follicular lymphoma Grade 3B per World Health Organization (WHO) 2016 classification and Primary mediastinal Bcell lymphomas. Indolent B-NHL who transformed into aggressive B-NHL and were previously treated with Rituximab-Cyclophosphamide, Hydroxydaunomycin, Oncovin, and Prednisone (R-CHOP) are eligible.

• Tumoral tissue (at diagnosis or relapse) available for central pathology review, exploratory endpoints and ancillary studies

• Positron-emission tomography (PET)-positive disease

• Patients must have received adequate first-line therapy including at a minimum: an anti-CD20 monoclonal antibody (rituximab or obinutuzumab), and Cyclophosphamide, Hydroxydaunomycin, Oncovin, and Prednisone (CHOP) or CHOP-like chemotherapy

• Relapsed or refractory disease after first-line chemoimmunotherapy (full dose of R-CHOP or R-CHOP-like regimen), documented by PET-scan

• At least 2 weeks must have elapsed since any prior systemic cancer therapy at the time the patient provides consent

• Patients must be autologous stem cell transplantation (ASCT)-ineligible

• Patients must be CAR-T-eligible

• Females of childbearing potential must have a negative serum or urine pregnancy test (females who have undergone surgical sterilization or who have been postmenopausal for at least 12 months are not considered to be of childbearing potential)

Exclusion Criteria:

• Patients who received more than one prior line of systemic therapy

• Patients who are intolerant to first-line therapy or who received suboptimal first-line therapy, including dose-reduced R-CHOP ("R-miniCHOP"), and those who discontinued prematurely first-line therapy due to toxicity are not eligible

• Prior CD19 targeted therapy

• Patients with cardiac atrial or cardiac ventricular lymphoma involvement

• Requirement for urgent therapy due to tumor mass effects, such as bowel obstruction or blood vessel compression

• Patient with clinically significant pleural effusion

• History of another primary malignancy that has not been in remission for at least 2 years (except for nonmelanoma skin cancer or carcinoma in situ (eg, cervix, bladder, breast))

• Patients with detectable Central Nervous System (CNS) lymphoma

• History or presence of non-malignant CNS disorder, such as seizure disorder requiring anti-convulsive therapy, cerebellar disease, or any autoimmune disease with CNS involvement disease

• Active hepatitis B or hepatitis C infection, positive serology of human immunodeficiency virus (HIV) and syphilis at the time of screening

• Uncontrolled systemic fungal, bacterial, viral or other infection despite appropriate antibiotics or other treatment at the time of leukapheresis or axi-cel administration

• History of any one of the following cardiovascular conditions within the past 6 months: Class III or IV heart failure as defined by the New York Heart Association, cardiac angioplasty or stenting, myocardial infarction, unstable angina, or other clinically significant cardiac disease

• History of autoimmune disease requiring systemic immunosuppression and/or systemic disease modifying agents within the last year

• History of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis per chest computed tomography (CT) scan at screening.

• History of severe immediate hypersensitivity reaction to tocilizumab or any of the agents used in this study

• History of severe immediate hypersensitivity reaction attributed to aminoglycosides, cyclophosphamide and fludarabine

• Treatment with a live, attenuated vaccine within 6 weeks prior to initiation of study treatment or anticipation of need for such a vaccine during the course of the study

• Women of childbearing potential who are pregnant or breastfeeding (from the time of consent during treatment and for at least 6 months after conditioning chemotherapy dosing or axicabtagene ciloleucel dosing, whichever is later)

• In the investigator's judgment, the patient is unlikely to complete all protocol-required study visits or procedures, including follow-up visits, or comply with the study requirements for participation

• Adult person unable to provide informed consent because of intellectual impairment, any serious medical condition, laboratory abnormality or psychiatric illness
