Abstract
Axicabtagene ciloleucel (axi-cel) and tisagenlecleucel (tisa-cel) are CD19-directed chimeric antigen receptor (CAR) T cell therapies approved for the treatment of relapsed/refractory aggressive B cell lymphomas. We present a multicenter retrospective study among centers that prescribe either commercial product to evaluate usage patterns, safety and efficacy outcomes, and resource utilization. Data collection included all patients from 8 US centers who underwent apheresis between May 1, 2018, and July 31, 2019. Patient selection, toxicity management, and disease assessment followed institutional practices. Cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) were graded according to American Society for Transplantation and Cellular Therapy consensus criteria, and tumor responses were assessed according to the Lugano 2014 classification scheme. A total of 260 patients underwent apheresis, including 168 (65%) for axi-cel and 92 (35%) for tisa-cel. Among the infused patients, the median age was 59 years for axi-cel recipients and 67 years for tisa-cel recipients (P < .001). The median time from apheresis to infusion was 28 days for axi-cel recipients and 45 days for tisa-cel recipients (P < .001). Sixty-one percent of the axi-cel recipients and 43% of the tisa-cel recipients would have been ineligible for the ZUMA-1 and JULIET trials, respectively. Grade ≥3 CRS occurred in 9% of axi-cel recipients and in 1% of tisa-cel recipients (P = .017), and grade ≥3 ICANS was seen in 38% of axi-cel recipients and 1% of tisa-cel recipients (P < .001). Inpatient cell therapy infusion was common (92% in axi-cel recipients, 37% in tisa-cel recipients). The day 90 overall response rate was 52% in the axi-cel group and 41% in the tisa-cel group (P =. 113), with complete response in 44% and 35%, respectively (P =. 319). Twelve-month progression-free survival (42% versus 32%; P =. 206) and overall survival (62% versus 59%; P =. 909) rates were comparable in the axi-cel and tisa-cel groups. Baseline characteristics differed between the 2 groups, although response rates and survival outcomes were comparable, albeit lower than those in the pivotal trials. Safety and resource utilization appear to be key differentiators between axi-cel and tisa-cel.
