Abstract: The invention relates to antibodies or a plurality of antibodies against human bone sialoprotein (BSP), characterized in that the antibodies bind to epitopes which are present only in human bone sialoprotein from tumor cells, the post-translational glycosylation of which is modified or incomplete in the region of amino acids of 120 to 135, containing the amino acids TGLAA (SEQ ID NO: 2), in comparison with normal bone sialoprotein from bones. The antibodies are put to use in an immunoassay for the diagnosis and prognosis of tumor diseases, in particular the diagnosis and prognosis of bone metastases in the case of primary breast carcinoma.

Abstract: Described is a novel gene and its encoded secreted tumor antigen, termed BPC-1, and to diagnostic and therapeutic methods and compositions useful in the management of various cancers which express BPC-1, particularly including prostate cancer and bladder cancer. In human normal tissues, BPC-1 is only expressed in certain tissues of the brain. However, BPC-1 is expressed at high levels in prostate cancer cells and is also expressed in bladder cancer cells. The structure of BPC-1 includes a signal sequence and a CUB domain. BPC-1 protein is secreted. Preliminary experimental evidence suggests that BPC-1 is directly involved in oncogenesis or maintenance of the transformed phenotype of cancer cells expressing BPC-1. BPC-1 also appears to bind specifically to a cellular protein expressed in prostate cancer cells and other cells.

Abstract: The present invention is based on the discovery that the cytoxicity of anti-desmocollin 2 (DSC2) antibodies can be used for treating various cancers including lung, colon, pancreatic, prostate, breast, gastric or liver cancers. Specifically, the present invention provides antibodies against DSC2 that have effector function. Furthermore, the present invention provides methods and pharmaceutical compositions that comprise anti-DSC2 antibody as an active ingredient for damaging DSC2-expressing cells via the effector function of the antibody.
Abstract: The invention provides polypeptides comprising a variant heavy chain variable framework domain (VFR). In some embodiments, the amino acids defining the VFR form a loop of an antigen binding pocket. In an embodiment, the polypeptide is a variable domain of a monobody and has a variant VFR. The polypeptide may optionally comprise one or more complementary determining regions (CDRs) of antibody variable domains. In an embodiment, the polypeptide is a variable domain of a monobody and has a variant VFR and one or more variant CDRs. Libraries of polypeptides that include a plurality of different antibody variable domains generated by creating diversity in a VFR, and optionally, one or more CDRs are provided and may be used as a source for identifying novel antigen binding polypeptides that can be used therapeutically or as reagents. The invention also provides fusion polypeptides, compositions, and methods for generating and using the polypeptides and libraries.

Abstract: The present invention relates to a combination of peptides that may be used for treatment of cancer. The peptide combination competes for the binding of specific neuropeptides at the plasma membrane and thereby alters the levels of key intracellular molecules implicated in cell proliferation, resulting in a broad spectrum of anticancer activity. The invention also relates to pharmaceutical compositions containing a combination of such peptide analogs.

Abstract: The present invention provides CDR-grated antibodies against human tissue factor that retain the high binding affinity of rodent monoclonal antibodies against tissue factor but have reduced immunogenicity. The present humanized antibodies are potent anticoagulants and are thus useful in the treatment and prophylaxis of human thrombotic disease. The invention also provides methods of making the CFR-grafted antibodies and pharmaceutical compositions for the attenuation or prevention of coagulation.

Abstract: The present invention provides binding molecules that specifically bind to ILT3, e.g., human ILT3 (hILT3), on antigen presenting cells, such as for example, monocytes, macrophages and dendritic cells (DC), e.g., monocyte-derived dendritic cells (MDDC). The binding molecules of the invention are characterized by binding to hILT3 with high affinity and downmodulating immune responses in vitro, e.g., downmodulating alloimmune responses; the production of inflammatory cytokines by dendritic cells, e.g., monocyte-derived dendritic cells (MDDC); the upregulation of costimulatory molecules by DC, e.g., MDDC; and/or calcium flux in monocytes. In addition, the binding molecules upregulate the expression of inhibitory receptors on dendritic cells, e.g., immature dendritic cells. Surprisingly, these same binding molecules which downmodulate immune responses in vitro, are immunostimulatory in vivo. Various aspects of the invention relate to binding molecules, and pharmaceutical compositions thereof.
