  • Publication number: 20240042023
    Abstract: Chimeric antigen receptors with an antibody-binding domain are presented that are preferably expressed from a recombinant cell in a therapeutic cell, and particularly in an NK-92 cell or derivative thereof. Notably, such modified cells have multiple modes of cytotoxicity, improved on-target cell killing, decreased off-target cell killing, show significant expression of the recombinant CAR, and/or increased CAR-mediated cytotoxicity.

  • Publication number: 20240016849
    Abstract: The present application is directed to methods and compositions that are useful for reducing the number of myeloid-derived suppressor cells (MDSC), tumor associated macrophages (TAM), or both in a subject. The methods include administering an antigen binding protein that binds to an antigen expressed by MDSC and/or TAM, or administering a modified T cell or NK-92 cell that expresses an antigen binding protein that binds to an antigen expressed by MDSC and/or TAM, or a combination of both, to a subject. For example, the antigen binding protein can bind to CD33 expressed by MDSC and/or TAM. The methods and compositions are useful for treating a disease associated with MDSC and/or TAM infiltration into a tissue or tumor.

  • Publication number: 20230272042
    Abstract: Recombinant NK cells, and especially recombinant NK-92 cells express a chimeric antigen receptor (CAR) having an intracellular domain of Fc?RI?. Notably, CAR constructs with an intracellular domain of Fc?RI? had a substantially prolonged duration of expression and significantly extended cytotoxicity over time. The CAR may be expressed from RNA and DNA, preferably as a tricistronic construct that further encodes CD16 and a cytokine to confer autocrine growth support. Advantageously, such constructs also enable high levels of transfection and expression of the recombinant proteins and provide a convenient selection marker to facilitate rapid production of recombinant NK/NK-92 cells.

  • Publication number: 20230172982
    Abstract: Provided are genetically modified NK cells expressing a chimeric antigen receptor targeting an BCMA superfamily receptor. The CAR can comprise an intracellular domain of Fc?RI? and further recombinant proteins expressed by the genetically modified NK cells are CD16, autocrine growth stimulating cytokines, and optionally one of IL-12, a TGF-beta trap, or a homing receptor. Also described are methods for treating a patient having or suspected of having a disease that is treatable with NK-92 cells, such as cancer, comprising administering to the patient the genetically modified NK cells.
