  • Publication number: 20210198342
    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: 20210187024
    Abstract: Provided herein are methods for inducing and maintaining an immune response to a tumor in a subject while treating a primary tumor. The methods include administering to the subject an effective amount of CAR-expressing-NK-92 cells to treat the primary tumor thereby inducing an anti-tumor immune response that is maintained in the subject, the maintained immune response preventing tumor regrowth and/or inhibiting generation of secondary tumors. Also provided are methods of producing an anti-tumor vaccine in a subject with a tumor. The methods include administering to the subject an effective amount of CAR-expressing-NK-92 cells to the subject thereby inducing an anti-tumor vaccine to the tumor in the subject.

  • Publication number: 20210169931
    Abstract: Compositions and methods are provided for generating a clonal population of transfected eukaryotic cells derived from a single cell. The method includes transfecting a population of eukaryotic cells with a multi-cistronic nucleic acid vector followed by non-antibiotic selection and characterization of the selected cells. The multi-cistronic nucleic acid vector encodes a selection element which may be an autocrine protein, miRNA, and/or shRNA.

  • Publication number: 20210038645
    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.
