  • Patent number: 11702633
    Abstract: The present invention relates to a method for effectively proliferating regulatory T cells, by which, particularly, in the presence of a fusion protein dimer comprising IL-2 protein or a variant thereof and CD80 protein or a fragment thereof, CD4+, CD25+, and CD127? T cells can be effectively proliferated. In particular, when combined with a predetermined cell culture medium, regulatory T cells such as CD4+, CD25+, and CD127? can be effectively and specifically proliferated. In addition, when the method is used, it has been confirmed that the survival rate of regulatory T cells is remarkably increased as compared to a conventionally used culture method using IL-2, and a significant increase in the yield of Foxp3+ regulatory T cells has been confirmed. Thus, such a proliferation method can be used in the field of cell therapeutic agents using regulatory T cells.

  • Patent number: 10640547
    Abstract: A method of treating a patient who has melanoma includes administering to said patient a composition containing a population of activated T cells that selectively recognize cells in the patient that aberrantly express a peptide. A pharmaceutical composition contains activated T cells that selectively recognize cells in a patient that aberrantly express a peptide, and a pharmaceutically acceptable carrier, in which the T cells bind to the peptide in a complex with an MHC class I molecule, and the composition is for treating the patient who has melanoma. A method of treating a patient who has melanoma includes administering to said patient a composition comprising a peptide in the form of a pharmaceutically acceptable salt, thereby inducing a T-cell response to the melanoma.

  • Patent number: 10588962
    Abstract: The present invention relates to the field of synthesizing and biologically evaluating of a novel class of carbohydrate-based vaccines. The new vaccines consist of a multi-modular structure which allows applying the vaccine to a whole variety of pathogenes. This method allows preparing vaccines against all pathogens expressing immunogenic carbohydrate antigens. As conjugation of antigenic carbohydrates to proteins is not required the conjugate vaccine is particularly heat stable. No refrigeration is required, a major drawback of protein-based vaccines.

  • Patent number: 10576132
    Abstract: The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.

  • Patent number: 10543232
    Abstract: A polyplex of a double stranded RNA (dsRNA) and a polymeric conjugate consists of a linear polyethyleneimine (PEI) covalently linked to one or more polyethylene glycol (PEG) moieties. Each PEG moiety is conjugated via a linker to a targeting moiety capable of binding to a cancer antigen. Exemplary cancer antigens include epidermal growth factor receptor (EGFR), human epidermal growth factor receptor 2 (HER2) and prostate surface membrane antigen (PSMA).
