    摘要: Eliciting a systemic antitumor immune response, in a patient who presents with or who is at risk of developing multiple metastatic tumors of a given cell type, entails, in one embodiment, inoculating a tumor in the patient with a pharmaceutical composition consisting essentially of (A) a herpes simplex virus (HSV) that infects tumor cells but that does not spread in normal cells and (B) a pharmaceutically acceptable vehicle for the virus, such that an immune response is induced that is specific for the tumor cell type and that kills cells of the inoculated tumor and of a non-inoculated tumor. In another embodiment, the pharmaceutical composition also comprises a defective HSV vector which contains an expressible nucleotide sequence encoding at least one immune modulator. In another embodiment, the pharmaceutical composition contains a second HSV that infects tumor cells but that does not spread in normal cells. According to the latter approach, both the first HSV and the second HSV may have genomes that comprise, respectively, an expressible nucleotide sequence coding for at least one immune modulator. In another embodiment, the pharmaceutical composition comprises, in addition to a herpes simplex virus (HSV) that infects tumor cells but that does not spread in normal cells, a viral vector comprising at least one expressible nucleotide sequence coding for at least one immune modulator.

    摘要: The present invention is in the field of drug delivery, and specifically, cationic liposome-based drug delivery. In embodiments, this invention provides methods of making ligand-targeted (e.g., antibody- or antibody fragment-targeted) liposomes useful for the delivery of liposomes to tumors, including brain tumors. In embodiments, the liposomes deliver temozolomide across the blood-brain barrier for treatment of primary or metastatic brain tumors. Additional cancers that can be treated with the liposomes include neuroendocrine tumors, melanoma, prostate, head and neck, ovarian, lung, liver, kidney, breast, urogenital, gastric, colorectal, cervical, vaginal, angiosarcoma, liposarcoma, rhabdomyosarcoma, choriocarcinoma, pancreatic, retinoblastoma and other types of cancer. In another embodiment the liposomes deliver melphalan for the treatment of multiple myeloma, other tumors of the blood or other solid tumors. In still other embodiments the liposomes can deliver other drugs such as pemetrexed or irinotecan for treatment of cancer or drugs including atropine for treatment of organophosphate poisoning.
