Large B-cell lymphomas (LBCL) are the most common types of non-Hodgkin lymphoma. Although outcomes have improved thanks to the introduction of rituximab-based chemoimmunotherapy, certain LBCL still represents a challenge because of initial resistance to therapy or recurrent relapses. Axicabtagene ciloleucel (axi-cel) and tisagenlecleucel (tisa-cel) are second-generation autologous CD19-targeted chimeric antigen receptor (CAR) T-cell therapies approved for patients with relapsed/refractory (R/R) LBCL, based on the results of phase II pivotal single-arm trials ZUMA-1 (for axi-cel) and JULIET (for tisa-cel). Here, we report patients outcomes with axi-cel and tisa-cel in the standard of care (SoC) setting for R/R LBCL, treated at our Institution. Data were collected from patients who underwent leukapheresis between August 2019 and February 2021. Toxicities were graded and managed according to the institution's guidelines. Responses were assessed as per Lugano 2014 classification. Of the 30 patients who underwent leukapheresis, 18 (60%) received axi-cel, while 12 (40%) tisa-cel. Grade 3 or higher cytokine release syndrome and neurotoxicity occurred in 10% and 16% patients, respectively. Best objective and complete response rates were 73.3% and 40%, respectively.

Abstract
Large B-cell lymphomas (LBCL) are the most common types of non-Hodgkin lymphoma. Although outcomes have improved thanks to the introduction of rituximab-based chemoimmunotherapy, certain LBCL still represents a challenge because of initial resistance to therapy or recurrent relapses. Axicabtagene ciloleucel (axi-cel) and tisagenlecleucel (tisa-cel) are second-generation autologous CD19-targeted chimeric antigen receptor (CAR) T-cell therapies approved for patients with relapsed/refractory (R/R) LBCL, based on the results of phase II pivotal single-arm trials ZUMA-1 (for axi-cel) and JULIET (for tisa-cel). Here, we report patients outcomes with axi-cel and tisa-cel in the standard of care (SoC) setting for R/R LBCL, treated at our Institution. Data were collected from patients who underwent leukapheresis between August 2019 and February 2021. Toxicities were graded and managed according to the institution's guidelines. Responses were assessed as per Lugano 2014 classification. Of the 30 patients who underwent leukapheresis, 18 (60%) received axi-cel, while 12 (40%) tisa-cel. Grade 3 or higher cytokine release syndrome and neurotoxicity occurred in 10% and 16% patients, respectively. Best objective and complete response rates were 73.3% and 40%, respectively. Treatment in SoC setting with CD19 CAR T-cell therapies for R/R LBCL showed a manageable safety profile and high objective response rate.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
