  • Publication number: 20210128615
    Abstract: The present invention pertains to methods and compounds useful in a therapy involving the administration of immune cells to a patient. The method of the invention involves the modification of cells of the immune system with agonists or antagonists of immune regulators such as Interleukin-10 (IL-10) or IL-6, in order to enhance and improve the immunological potential of the immune cells for therapy. Cells modified according to the method of the invention can be administered to a patient to support a treatment of proliferative diseases such as cancer or autoimmune disorders.

  • Patent number: 10556969
    Abstract: The present invention relates to multi-functional proteins which comprise (i) a signal peptide, (ii) a target specific recognition domain, (iii) a linker region, connecting domain (ii) and domain (iv) which comprises a specific modified hinge region of the human CD8 alpha-chain, and (iv) an effector domain. The present invention furthermore relates to nucleic acids encoding the proteins, expression constructs for expressing the protein in a host cell and host cells. The proteins of the invention are chimeric antigen receptors with an optimized linker or hinge region that are suitable for generating target-specific effector cells, for use as a medicament, in particular in the treatment of cancer and in adoptive, target-cell specific immunotherapy.

  • Patent number: 10351612
    Abstract: The present invention relates to the use of interleukin-15 (IL-15) as selectable marker for gene transfer, preferably of at least one gene of therapeutic interest, into a mammalian cell or cell line, in particular a human cell or cell line. The present invention furthermore relates to transgenic mammalian cells or cell lines expressing IL-15 as selectable marker and co-expressing at least one protein of interest encoded by at least one gene of interest, which is preferably a protein of therapeutic interest. The present invention is in particular suitable for chimeric antigen receptors (CARs) as the gene or protein of interest and their expression in lymphocytes. The transgenic mammalian cells and cell lines are furthermore suitable for use as a medicament, in particular in the treatment of cancer and in immunotherapy, such as adoptive, target-cell specific immunotherapy.
