          Abstract

          Garcia et al. discover a novel immunotherapy approach by engineering naturally occurring mutations in therapeutic T cells to strongly elevate anti‐tumor activity. The authors identify a gene fusion, CARD11–PIK3R3, to increase activator protein 1 and nuclear factor–κB signaling, interleukin‐2 production, and tumor death in vitro and in vivo

            CRISPR-engineered T cells in patients with refractory cancer

            CRISPR-Cas9 gene editing provides a powerful tool to enhance the natural ability of human T cells to fight cancer. We report a first-in-human phase I clinical trial to test the safety and feasibility of multiplex CRISPR-Cas9 editing to engineer T cells in three patients with refractory cancer. Two genes encoding the endogenous T cell receptor (TCR) chains, TCRα ( TRAC ) and TCRβ ( TRBC ) were deleted in T cells to reduce TCR mispairing and to enhance the expression of a synthetic, cancer-specific TCR transgene (NY-ESO-1). Removal of a third gene encoding PD-1 ( PDCD1 ), was performed to improve anti-tumor immunity. Adoptive transfer of engineered T cells into patients resulted in durable engraftment with edits at all three genomic loci. Though chromosomal translocations were detected, the frequency decreased over time. Modified T cells persisted for up to 9 months suggesting that immunogenicity is minimal under these conditions and demonstrating the feasibility of CRISPR gene-editing for cancer immunotherapy.
