The goal of this clinical study is to compare the study drug KITE-753 versus axicabtagene ciloleucel (axi-cel) in adult participants with relapsed or refractory (r/r) large B-cell lymphoma (LBCL) after one prior line of therapy.
The primary objective of this study is to evaluate the efficacy of KITE-753 versus axicabtagene ciloleucel.
Progressive disease (PD) and/or Deauville score of 5 (irrespective of the response designation) as the best response during the first-line treatment or as the end of treatment response following first-line therapy.
Stable disease (SD) after at least 4 cycles of first-line therapy (eg, 4 cycles of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP)).
PR as best response after at least 6 cycles of first-line therapy (eg, 6 cycles of R-CHOP).
Note: A biopsy is recommended to confirm residual disease.
Prior CAR T-cell therapy or other cell-based therapy.
History of malignancy other than nonmelanoma skin cancer or carcinoma in situ (eg, cervix, bladder, or breast) unless disease-free and without anti-cancer therapy (with the exception of hormonal therapy in the case of breast cancer) for at least 3 years. Individuals with asymptomatic localized low-grade prostate cancer for which a watch-and-wait approach is standard of care are eligible.
Individuals with the following LBCL fifth edition of WHO criteria subtypes: Richter's transformation of chronic leukemic lymphoma, small lymphocytic lymphoma, Burkitt lymphoma, lymphoplasmacytic lymphoma, T-cell/histiocyte-rich LBCL, mediastinal gray zone lymphoma, plasmablastic lymphoma, intravascular LBCL, primary central nervous system (CNS) lymphoma, primary vitreoretinal LBCL, fibrin-associated LBCL, fluid overload-associated LBCL lymphomatoid granulomatosis, high-grade B-cell lymphoma (HGBCL) with 11q aberrations, anaplastic lymphoma kinase-positive LBCL, LBCL with Interferon Regulatory Factor 4 (IRF4) rearrangement, and transformed from Hodgkin's lymphoma (HL). Note: Individuals with primary testicular LBCL are eligible.
History of a severe, immediate hypersensitivity reaction attributed to aminoglycosides
