Abstrakt: Through two decades of research and development, adoptive cell therapies (ACTs) have revolutionized treatment for hematologic malignancies. Many of the seven US Food and Drug Administration (FDA)-approved products are proven to be a curative last line of defense against said malignancies. The ACTs, known more commonly as chimeric antigen receptor (CAR) T-cells, utilize engineered lymphocytes to target and destroy cancer cells in a patient-specific, major histocompatibility complex (MHC)-independent manner, acting as "living drugs" that adapt to and surveil the body post-treatment. Despite their efficacy, CAR T-cell therapies present unique challenges in preclinical safety assessment. The safety and pharmacokinetics of CAR T-cells are influenced by numerous factors including donor and recipient characteristics, product design, and manufacturing processes that are not well-predicted by existing in vitro and in vivo preclinical safety models. The CAR therapy-mediated toxicities in clinical settings primarily arise from unintended targeting of non-tumor cells, potential tumorigenicity, and severe immune activation syndromes like cytokine release syndrome and immune effector cell-associated neurotoxicity. Addressing these issues necessitates a deep understanding of CAR target expression in normal tissues, inclusive of the spatial microanatomical distribution, off-target screening, and a deep understanding CAR cell manufacturing practices and immunopathology.
