  • Publication number: 20230390392
    Abstract: Several embodiments of the methods and compositions disclosed herein relate to immune cells that are engineered to express chimeric antigen receptors (CAR) and/or genetically modified to reduce potential side effects of cellular immunotherapy. Several embodiments relate to genetic modifications to the immune cells, such as Natural Killer (NK) cells, to reduce, substantially, reduce, or eliminate expression of a combination of genes and their corresponding proteins. In several embodiments, one edit is to reduce expression of a marker by the immune cells that would otherwise cause them to be self-targeted by the CAR and at least two additional gene edits to enhance the cytotoxicity and/or persistence of the resulting cells. In several embodiments, the CAR targets CD70, and in some embodiments is used for renal cell carcinoma immunotherapy.

  • Publication number: 20230265390
    Abstract: Several embodiments disclosed herein relate to methods and compositions for enhanced expansion of NK cells in culture. In several embodiments, the methods utilize one or more soluble interleukins as culture media supplements at one or more time points during expansion of the NK cell, or other immune cell, the expansion employing a feeder cell population.

  • Publication number: 20230028399
    Abstract: Provided for herein in several embodiments are immune cell-based compositions comprising BCMA-directed chimeric antigen receptors (CAR). In several embodiments, the immune-cell based compositions also target an additional tumor marker and/or an additional epitope of BCMA. In several embodiments, the BCMA-directed CAR is expressed in a Natural Killer cell. In several embodiments, combinations of BCMA-CAR-expressing NK cells are administered in conjunction with, for example CAR-expressing NK cells and/or CAR-expressing T cells that are directed to an additional cancer marker and/or an additional epitope of BCMA. Also provided for herein are methods and uses of the chimeric antigen receptors in immunotherapy.

  • Publication number: 20230002471
    Abstract: Several embodiments disclosed herein relate to the compositions comprising engineered Natural Killer (NK) cells that express a chimeric receptor, the chimeric receptor imparting to the NK cells an enhanced ability to target specific cells, such as cancerous cells or those affected by an infectious disease. Several embodiments relate to NK cells that target cells expressing natural ligands of NKG2D, where the NK cells comprise transmembrane and/or signaling domains that lead to cytotoxic and/or cytolytic effects when the NK cells bind a target cell. Uses of NK cell compositions to treat diseases are also provided for in several embodiments.
