Abstract

The present disclosure provides processes for genetically engineering T cells, such as primary CD4+ T cells and/or CD8+ T cells, for use in cell therapy that does not involve expanding the cells. In particular aspects, the provided processes successfully generate compositions of engineered T cells, such as containing populations of engineered T cells, that express a chimeric antigen receptor (CAR) within a shortened amount of time as compared to alternative engineering processes, such as processes that involve expanding the cells. In certain aspects, the provided processes successfully generate a composition of engineered T cells suitable for use in cell therapy within 4 days from when the process to stimulate or activate the cells is initiated. In some aspects, the resulting engineered cell compositions are composed of cell population that are less differentiated, less exhausted, and more potent than engineered T cell compositions generated by other means, such as by processes that involve expanding the cells. Also provided are compositions of T cells generated by the provided methods and their uses for treating subjects.
