Abstract: Provided herein are engineered T cells, expressing a chimeric receptor comprising an antigen-binding domain fused to an endogenous invariant CD3 chain of the immunoglobulin superfamily (invariant CD3-IgSF). In some embodiments, the engineered T cells contain a modified invariant CD3-IgSF chain locus that encodes the chimeric receptor. Also provided are cell compositions containing the engineered T cells, nucleic acids for engineering cells, and methods, kits and articles of manufacture for producing the engineered cells, such as by targeting a transgene encoding a portion of a chimeric receptor for integration into an invariant CD3-IgSF chain genomic locus. In some embodiments, the engineered cells, e.g. T cells, can be used in connection with cell therapy, including in connection with cancer immunotherapy comprising adoptive transfer of the engineered cells.

Abstract: Provided in some aspects are compositions of cells for treating subjects with disease and conditions such as non-Hodgkin's lymphoma (NHL), and related methods, compositions, uses and articles of manufacture. In some embodiments, the disease or condition is a B-cell non-Hodgkin lymphoma (B-cell NHL). The cells generally express recombinant receptors such as chimeric antigen receptors (CARs) for targeting an antigen, such as CD 19, on cells of the lymphoma.

Abstract: Provided in some aspects are compositions of cells for treating subjects with disease and conditions such as multiple myeloma (MM), and related methods, compositions, uses and articles of manufacture. In some embodiments, the disease or condition is a relapsed or refractory multiple myeloma (r/r MM). The cells generally express recombinant receptors such as chimeric antigen receptors (CARs) for targeting an antigen, such as BCMA, on cells of the myeloma.

Abstract: Provided herein are methods for selecting and stimulating a plurality of cells in a sample of cells using column chromatography, and collecting the cells without using additional steps or reagents to facilitate detachment of the cells from the column. In some aspects, the methods provided herein reduce the time needed to generate a population of selected and stimulated cells useful for genetic engineering, and ultimately, cell therapy, compared to existing methods. Also provided are articles of manufacture and apparatus thereof.

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.
