  • Patent number: 7771715
    Abstract: The present invention is a recombinant vector encoding and expressing at least three or more costimulatory molecules. The recombinant vector may additionally contain a gene encoding one or more target antigens or immunological epitope thereof. The synergistic effect of these costimulatory molecules on the enhanced activation of T cells is demonstrated. The degree of T-cell activation using recombinant vectors containing genes encoding three costimulatory molecules was far greater than the sum of recombinant vector constructs containing one costimulatory molecule and greater than the use of two costimulatory molecules. Results employing the triple costimulatory vectors were most dramatic under conditions of either low levels of first signal or low stimulator to T-cell ratios. This phenomenon was observed with both isolated CD4+ and CD8+ T cells.

  • Patent number: 7118738
    Abstract: Recombinant pox viruses capable of expressing an immunogenic fragment of the MUC1 tumor-associated antigen are disclosed. The recombinant viruses can be used as vaccines to prevent the establishment of or treat tumors or pre-tumorous cells expressing the MUC1 tumor-associated antigen. The vaccines can be provided as an admixture comprising: (1) a recombinant pox virus encoding the immunogenic fragment of the MUC1 tumor-associated antigen, and (2) a recombinant pox virus encoding a T-cell co-stimulatory factor. The vaccine admixture can be used, e.g., to prevent establishment of tumors or pre-tumorous cells expressing the MUC1 tumor-associated antigen. The MUC1 specific cytotoxic T-cells can be isolated and expanded and used in a method for treating a host having a tumor expressing MCU1 positive tumor cells.

  • Publication number: 20040091995
    Abstract: Replication-defective recombinant poxvirus encoding granulocyte-macrophage colony-stimulating factor (GM-CSF) are disclosed for use in enriching an immunization site with antigen-presenting cells (APC), for enhancing an immunological response to antigen or immunological epitopes by functioning as a biological adjuvant, for prevention or treatment of neutropenia, and for the treatment of myeloidysplastic syndromes. Compositions comprising a replication-defective recombinant virus encoding GM-CSF alone or in combination with a recombinant virus encoding an antigen and optionally encoding an immunostimulatory molecule are disclosed for enhancing antigen-specific immunological responses, in particular enhancing tumor antigen responses for anti-tumor therapy. Methods for enriching an immunization site with APC and for enhancing immunological responses to an antigen or immunological epitope using replication-defective recombinant poxvirus encoding GM-CSF are disclosed.
