  • Publication number: 20090170129
    Abstract: Endothelial cells are detected in a blood sample by enriching the endothelial cells from the blood sample followed by performing on the enriched endothelial cells an immunoassay capable of detecting antigens expressed by the endothelial cells. The immunoassay is capable of detecting antigen expressed from 300 endothelial cells per milliliter of blood. The method can be used for assaying mature circulating endothelial cells or circulating endothelial progenitor cells.

  • Publication number: 20090098138
    Abstract: The protein EGFR, ERCC1, RRM1, thymidylate synthase, or beta-tubulin from cancer cells is detected in a blood sample by enriching the cancer cells from the blood sample followed by performing on the enriched cancer cells an immunoassay capable of detecting the proteins mentioned above. Cancer patients overexpressing EGFR are treated with an anti-EGFR agent, for example cetuximab, panitumumab, erlotinib or gefitinib.

  • Publication number: 20090081161
    Abstract: The subject invention relates to viruses that are able to replicate and thereby kill neoplastic cells with a deficiency in the IFN-mediated antiviral response, and their use in treating neoplastic disease including cancer and large tumors. RNA and DNA viruses are useful in this regard. The invention also relates to methods for the selection, design, purification and use of such viruses for cancer therapy.

  • Publication number: 20080261243
    Abstract: The expression of Her-2/neu protein on circulating cancer cells in a blood sample is detected by isolating the cancer cells from the blood sample and then performing on the isolated cancer cells a sensitive Her-2/neu immunoassay. A positive result indicates the expression of Her-2/neu on cancer cells in the blood sample. This method can be used to identify cancer patients who are likely to benefit from treatment with an anticancer agent that targets Her-2/neu, such as trastuzumab (HERCEPTIN).

  • Publication number: 20080166784
    Abstract: Envelope viruses (e.g. Newcastle disease virus (NDV)) are formulated for storage at moderately cold temperatures (e.g. ?20 C). The formulation is an aqueous solution containing the enveloped virus at a concentration of from 106 PFU/mL to 1012 PFU/mL; and a non-reducing saccharide (e.g. sucrose). When the non-reducing saccharide is a disaccharide it is present in the solution at a concentration of from 5% (w/v) to 50% (w/v), and when it is a monosaccharide it is present in the solution at a concentration of from 2.5% (w/v) to 25% (w/v). The solution has an osmotic pressure of about 250 mOs or higher, and has a pH of from 5 to 10.

  • Publication number: 20070207149
    Abstract: Mammalian subjects having a neoplasm are treated with a virus and a camptothecin compound, for example irinotecan or topotecan. The virus is selected from the group consisting of a Newcastle disease virus, a measles virus, a vesicular stomatitis virus, an influenza virus, a Sindbis virus, a picornavirus, and a myxoma virus. The treatment can also include administration of a monoclonal antibody against epidermal growth factor receptor, for example cetuximab.

  • Publication number: 20070166287
    Abstract: The present invention is directed to a method of reducing the viability of a tumor cell involving administering a virus that is not a common human pathogen to the tumor cell. Preferably, the virus exhibits differential susceptibility, in that normal cells are not affected by the virus. This differential susceptibility is more pronounced in the presence of interferon. The tumor cell is characterized by having low levels, or no, PKR activity, or as being PKR?/?, STAT1?/? or both PKR?/? and STAT1?/?. The virus is selected from the group consisting of Rhabdovirus and picomavirus, and preferably is vesicular stomatitis virus (VSV) or a derivative thereof.
