  • Publication number: 20240084255
    Abstract: An improved method of culturing cells for cell therapy applications that includes growing desired cells in the presence of antigen-presenting cells and/or feeder cells and with medium volume to surface area ratio of up to 1 ml/cm2 if the growth surface is not comprised of gas permeable material and up to 2 ml/cm2 if the growth surface is comprised of gas permeable material. The desired cells are at a surface density of less than 0.5×106 cells/cm2 at the onset of a production cycle, and the surface density of the desired cells plus the surface density of the antigen presenting cells and/or feeder cells are at least about 1.25×105 cells/cm2.

  • Publication number: 20240002797
    Abstract: Production and use of novel therapeutic cells, called T-Vehicles, in the allogeneic Adoptive Cell Therapy setting allows a wide range of therapeutic benefits to accrue with minimal or no risk of GVHD. T-Vehicles are created from donor T cells that are altered to contain therapeutic attributes that do not include their native antigen receptors and can deliver therapeutic benefits irrelevant of their native antigen specificity. T-Vehicles can possess highly restricted native antigen specificity that renders them unable to recognize antigens present on normal cells and incapable of initiating GVHD, making them ideal transport vehicles to deliver various therapeutic attributes in vivo. In essence, production and use of T-Vehicles is a paradigm shift that opens the door to therapeutic application of T cells in ways not previously contemplated, independent of whether or not there is an HLA match between the donor and the recipient.
