  • Patent number: 9512158
    Abstract: The invention relates to methods and compositions for causing the selective targeting and killing of tumor cells. The present invention describes prophylactic or therapeutic cancer vaccines based on purified TAA proteins or TAA-derived synthetic peptides altered by chemical, enzymatic or chemo-enzymatic methods to introduce ?Gal epitopes or ?Gal glycomimetic epitopes, in order to allow for enhanced opsonization of the antigen by natural anti-?Gal antibodies to stimulate TAA capture and presentation, thereby inducing a humoral and cellular immune response to the TAA expressed by a tumor. The animal's immune system thus is stimulated to produce tumor specific cytotoxic cells and antibodies which will attack and kill tumor cells present in the animal.

  • Patent number: 9174942
    Abstract: Presently provided are compounds according to the formula (I) or (II), and pharmaceutical compositions comprising the compounds, wherein R1, R4, and R5 are defined herein. Such compounds and compositions are useful for modulating an activity of indoleamine 2,3-dioxygenase; treating indoleamine 2,3-dioxygenase (IDO) mediated immunosuppression; treating a medical conditions that benefit from the inhibition of enzymatic activity of indoleamine-2,3-dioxygenase; enhancing the effectiveness of an anti-cancer treatment comprising administering an anti-cancer agent; treating tumor-specific immunosuppression associated with cancer; and treating immunosuppression associated with an infectious disease.

  • Publication number: 20130149331
    Abstract: The present invention provides an immunogenic composition comprising a T-cell antigen in association with a rhamnose monosaccharide and/or Forssman disaccharide, and corresponding methods for inducing immune response. The T-cell antigen may be for example, a tumor vaccine, such as a tumor cell or one or more tumor antigens. The invention takes advantage of the naturally high titers of anti-Rhamnose and/or anti-Forssman disaccharide in humans to target vaccine compositions to antigen presenting cells.
