  • Patent number: 6251603
    Abstract: The invention relates to methods for determining tumor status by determining antibodies specific to NY-ESO-1 in patient samples. One can determine whether a cancerous condition is progressing, regressing, or remaining stable by determining antibodies against NY-ESO-1 in a patient sample, and comparing the value obtained to a prior value. When the tumor in question expresses NY-ESO-1, a change in this value is indicative of a change in status of the cancerous condition.

  • Patent number: 6217868
    Abstract: The invention provides for the production of several humanized murine antibodies specific for the antigen FB5, which is recognized by the murine antibody FB5. The FB5 antigen is expressed on the luminal surface of vascular endothelial cells of a wide range of malignant tumors. The invention also provides for numerous polynucleotide encoding humanized FB5 specific antibodies, expression vectors for producing humanized FB5 specific antibodies, and host cells for the recombinant production of the humanized antibodies. The invention also provides methods for detecting cancerous cells (in vitro and in vivo) using humanized FB5 specific antibodies. Additionally, the invention provides methods of treating cancer using FB5 specific antibodies.

  • Patent number: 6140050
    Abstract: The invention relates to assays for determining breast cancer or melanoma. It has been found that the accuracy of such assays can be improved by assaying samples for three or more known tumor rejection antigen precursors. For breast cancer, the tumor rejection antigen precursors known as SCP-1, NY-ESO-1, and SSX-2 are assayed. For melanoma, SSX-2, NY-ESO-1, and MAGE-3 are assayed. Additional known tumor rejection antigen precursors can also be determined to confirm the assays. It is preferred to carry these out via polymerase chain reactions.

  • Patent number: 6124106
    Abstract: The invention provides for the production of several humanized murine antibodies specific for the antigen LK26, which is recognized by the murine antibody LK26. This antigen is expressed in all choriocarcinoma, teratocarcinoma and renal cancer cell lines whereas it is not expressed on cell lines of leukaemias, lymphomas, neuroectodermally-derived and epithelial tumour cell lines (excepting a small subset of epithelial cell lines). Furthermore, whereas renal cancer cell lines express the LK26 antigen, normal renal epithelial cells do not. Similarly, with the exception of the trophoblast, all normal adult and fetal tissues tested are negative for the LK26 phenotype. The invention also provides for numerous polynucleotide encoding humanized LK26 specific antibodies, expression vectors for producing humanized LK26 specific antibodies, and host cells for the recombinant production of the humanized antibodies.

  • Patent number: 5977329
    Abstract: The invention describes an improved method for making monosialoganglioside GM3 and its intermediates. Following reaction of a neuraminic acid donor and a lactose acceptor in the presence of an acid catalyst, the .alpha. and .beta. isomers of GM3 are formed. The .alpha. isomer is converted to a lactone, via action of a ring forming basic catalyst, which is then separable from the .beta. isomer. The lactone is then treated with a basic catalyst in the presence of an alcohol, to form GM3 or a GM3 intermediate.

  • Patent number: 5874060
    Abstract: The invention provides for the production of several humanized murine antibodies specific for the antigen Lewis Y, which is recognized by the murine antibody Lewis Y. The Lewis Y antigen is expressed in normal tissues but the level of expression is higher in certain tumor types so that the antigen can be used as a marker for cells of some breast, colon, gastric, esophageal, pancreatic, duodenal, lung, bladder and renal carcinomas and gastric and islet cell neuroendocrine tumors. The invention also provides for numerous polynucleotide encoding humanized Lewis Y specific antibodies, expression vectors for producing humanized Lewis Y specific antibodies, and host cells for the recombinant production of the humanized antibodies.
