Abstract: Provided herein are methods of producing engineered T cell compositions enriched for CD57 negative and/or CD27 positive T cells, such as from a plurality of donors. In some embodiments, the T cells are engineered with a recombinant receptor, such as a chimeric antigen receptor (CAR). Also provided herein are engineered T cell compositions containing T cells enriched for CD57 negative and/or CD27 positive T cells derived from a plurality of different donors, including compositions in which the T cells are engineered with or express a recombinant receptor (e.g. CAR). Also provided are methods of using the engineered T cell compositions in adoptive therapy, including in connection for cancer immunotherapy, such as for allogeneic therapies or for administration to one or more subjects in which the T cells are not derived from the subject(s) to whom the compositions are administered.

Abstract: An automated method of T cell scale down processing. The method including: activating T cells by automatically contacting the T cells with one or more activation reagents; transducing the T cells by automatically contacting the T cells with a recombinant viral vector; automatically inoculating T cells; automatically expanding the T cells; optionally, automatically debeading the T cells; and automatically harvesting the T cells. A system for an automated method of T cell scale down processing.
