"In vivo efficacy was evaluated using a systemic NALM-6 challenge in immune-deficient NSG mice at HIP CD19 CAR T cell doses of 5e5 and 5e6 cells per animal...Outperforming donors also showed reduced expression of MHC class II of alpha and beta heterodimers (HLA-DQA1 and HLA-DQB1). The information collected across phenotypic and functional comparisons will be compared with clinical performance."

The initial patient, a 74-year-old male with CLL (unmutated IGHV, del(11q), BTK C481S mutation) and 3 prior lines of therapy (FCR, ibrutinib, venetoclax + rituximab), received a LD regimen of cyclophosphamide 500 mg/m 2 and fludarabine 24 mg/m 2 (daily for 3 days) followed by a starting dose of 60 million CAR+ SC291 cells (of which approximately 80% are fully HIP engineered cells). Immune assays demonstrated that the CD19 HIP CAR T cell subpopulation effectively evades the host adaptive and innate immune responses and could overcome the allogeneic barrier in humans. Additional data from the ARDENT study will be presented at the time of the conference.
