Study to Compare Axicabtagene Ciloleucel With Standard of Care Therapy as First-line Treatment in Participants With High-risk Large B-cell Lymphoma

Open to people ages 18 years and up

• Histologically confirmed large B cell lymphoma (LBCL) based on 2016 World Health Organization (WHO) classification by local pathology lab assessment, including of the following:
  • Diffuse large B-cell lymphoma (DLBCL), not otherwise specified (NOS)
  • High-grade B-cell lymphoma (HGBL)
• Note: Transformed DLBCL from follicular lymphoma or from marginal zone lymphoma is eligible if no prior treatment with anthracycline-containing regimen.
• High-risk disease defined as an International Prognostic Index (IPI) score of 4 or 5 at initial diagnosis.
• Have received only 1 cycle of rituximab plus chemotherapy (R-chemotherapy).
• Adequate bone marrow, renal, hepatic, pulmonary, and cardiac function.
• Females of childbearing potential must have a negative serum or urine pregnancy test.

• The following WHO 2016 subcategories by local assessment:
  • T-cell/histiocyte-rich LBCL
  • Primary DLBCL of the central nervous system (CNS)
  • Primary mediastinal (thymic) LBCL
  • B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and classical Hodgkin lymphoma
  • Burkitt lymphoma
  • History of Richter's transformation of chronic lymphocytic leukemia
• Presence of detectable cerebrospinal fluid (CSF)-malignant cells, brain metastases, or a history of CNS involvement of lymphoma.
• Presence of cardiac lymphoma involvement.
• Any prior treatment for LBCL other than the 1 cycle of R-chemotherapy.
• History of severe immediate hypersensitivity reaction to any of the agents used in this study.
• Presence of CNS disorder. History of stroke, transient ischemic attack, or posterior reversible encephalopathy syndrome (PRES) within 12 months prior to enrollment.
• History of acute or chronic active hepatitis B or C infection.
• Positive for human immunodeficiency virus (HIV) unless taking appropriate anti-HIV medications, with an undetectable viral load by PCR and with a cluster of differentiation 4 (CD4) count > 200 cells/uL.
• Medical conditions or residual toxicities from prior therapies likely to interfere with assessment of safety or efficacy of study treatment. Please refer to protocol for further details.
• History of clinically significant cardiac disease within 12 months before enrollment.
• History of any medical condition requiring maintenance systemic immunosuppression/systemic disease modifying agents within the last 2 years.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
