The Sleeping Beauty platform genetically modifies T cells with DNA plasmids, instead of virus, to express T-cell receptors (TCRs) to target specific antigens in solid tumors, and chimeric antigen receptors (CARs) to target CD19 in blood cancers with membrane-bound interleukin 15 (mbIL15) and a kill switch for under 2-day manufacturing. The Sleeping Beauty platform is being advanced in collaboration with the National Cancer Institute, The University of Texas MD Anderson Cancer Center and Eden BioCell. The Company also is developing its Controlled IL-12 platform or Ad-RTS-hIL-12 plus veledimex as monotherapy and in combination with immune checkpoint inhibitors to treat brain cancer, including a collaboration with Regeneron Pharmaceuticals.
