Allogeneic CAR T Cells: Complex Cellular Therapy Designs Test the Limits of Our Preclinical Models.

ABSTRACT

All chimeric antigen receptor (CAR) T-cell products currently approved by the FDA are autologous, which poses several challenges for widespread use. In this issue, Degagné and colleagues present their preclinical research on creating off-the-shelf CAR T cells for multiple myeloma. They utilized the CRISPR/Cas12a genome editing platform and gene knock-in techniques to eliminate alloreactivity and decrease susceptibility to natural killer (NK)-cell elimination. This work has led to an ongoing phase I trial of off-the-shelf CAR T cells for multiple myeloma treatment. See related article by Degagné et al., p. 462 (2).
