Aucatzyl: animal efficacy model or human cells?
obecabtagene autoleucel · CD19 CAR-T
Efficacy evidence
Systemic human tumor xenograft mouse model: single IV dose of obe-cel significantly reduced tumor burden by Day 12
“In vivo pharmacology studies demonstrated that a single intravenous administration of obe-cel at a dose level of 2.5 × 106 CAT19 CAR T cells/animal in a systemic human tumor xenograft mouse model resulted in significant reduction in tumor burden on Day 12 post administration.”
Why that model
Patient-specific human T cells do not engraft in immunocompetent animals, so immunodeficient xenograft models used
“Aucatzyl, a patient-specific product, is not appropriate for administration to immunocompetent animals, as the T cells will not engraft.”
Reviewer's view of the efficacy data
EMA: lower-affinity CAT CAR T cells showed enhanced anti-tumour responses vs FMC63 under stress conditions; clinical translation unknown
“Together, all these non-clinical results indicate that, under conditions designed to give CAR T cells a numeric disadvantage relative to the number of tumour cells, lower affinity CD19 CAT CAR T cells mediate enhanced anti-tumour responses and expansion as compared to higher affinity CD19 (FMC63) CAR T cells. Whether this translates into a clinical effect is not known.”
