Outpatient CAR T infusions feasible using liso-cel


 

REPORTING FROM THE 2018 BMT TANDEM MEETINGS


Although all but one required hospital admission, at a median of 5 days postinfusion (range, 4-22 days), there had been no intensive care unit admissions, and no outpatient recipients had experienced severe cytokine release syndrome (CRS) or neurotoxicity. All admitted patients presented with fever.

Among the study population, “Cytokine release syndrome was only seen in 35% of our entire dataset,” with neurologic toxicity seen in 19% of participants, Dr. Abramson said. “The majority of subjects had no CRS and no toxicity,” he said. Severe CRS occurred in 1% of the study population, and severe neurotoxicity in 12%. There were no deaths related to either complication.

Dr. Abramson reported these results from the TRANSCEND NHL 001 trial, a seamless design phase 1 pivotal trial of liso-cel enrolling patients with relapsed and refractory aggressive B cell non-Hodgkin lymphoma (NHL). Liso-cel delivers CD19-directed CD4 and CD8 CAR T cells in a 1:1 ratio, said Dr. Abramson, director of the lymphoma program at the Massachusetts General Hospital Cancer Center, Boston.

A total of 91 patients were randomized to one of the three dose-finding cohorts of the multicenter trial of liso-cel. One cohort received 5 x 107 cells in a single dose; a second cohort received the same number of cells but in two doses administered 14 days apart; the third cohort received a single dose of 1 x 108 cells.
