Abstract: A non-viral vector, comprising, from 5? to 3?, flanked by two transposon terminal inverted repeats, an inducible promoter, a first coding region comprising a specific combination of genes whose expression is localized to a tumor microenviorment and their function being mediators of CAR persistence and anti-tumor mechanisms to stimulate or enhance a patient anti-tumor response; a second promoter and coding region for expressing one or more artificial immunosurveillance chimeric antigen receptors (AI-CAR), and a truncated CD20 or truncated EGFR safety target. A polycistronic mRNA comprised of a specific combination of transiently expressed anti-tumor mechanisms designed to stimulate a patient anti-tumor response the same as an AI-CAR vector.
