Methods and compositions for treating cancer

1. A method of treating melanoma, comprising selecting a subject with melanoma and administering to the subject in need thereof an effective amount of a non-fusogenic HSV-2 virus, wherein the non-fusogenic HSV-2 virus lacks protein kinase activity of ICP10 and has a mutation in the ICP10 kinase catalytic domain but retains the transmembrane domain of IPC10.

2. The method of claim 1 , wherein the lack of protein kinase activity of ICP10 is the result of a mutation selected from the group consisting of a deletion, an insertion and a point mutation.

3. The method of claim 1 , wherein the HSV-2 virus has a deletion in the ICP10 kinase catalytic domain.

4. The method of claim 3 , wherein the HSV-2 virus is delta-PK, wherein the delta-PK virus lacks amino acids 106-445 of ICP10.

5. The method of claim 1 , further comprising co-administering another anti-cancer agent to the subject.

6. The method of claim 5 , wherein the anti-cancer agent is selected from the group consisting of Abraxane, Aldara, Alimta, Aprepitant, Arimidex, Aromasin, Arranon, Arsenic Trioxide, Avastin, Bevacizumab, Bexarotene, Bortezomib, Cetuximab, Clofarabine, Clofarex, Clolar, Dacogen, Dasatinib, Ellence, Eloxatin, Emend, Erlotinib, Faslodex, Femara, Fulvestrant, Gefitinib, Gemtuzumab Ozogamicin, Gemzar, Gleevec, Herceptin, Hycamtin, Imatinib Mesylate, Iressa, Kepivance, Lenalidomide, Levulan, Methazolastone, Mylosar, Mylotarg, Nanoparticle Paclitaxel, Nelarabine, Nexavar, Nolvadex, Oncaspar, Oxaliplatin, Paclitaxel, Paclitaxel Albumin-stabilized Nanoparticle Formulation, Palifermin, Panitumumab, Pegaspargase, Pemetrexed Disodium, Platinol-AQ, Platinol, Revlimid, Rituxan, Sclerosol Intrapleural Aerosol, Sorafenib Tosylate, Sprycel, Sunitinib Malate, Sutent, Synovir, Tamoxifen, Tarceva, Targretin, Taxol, Taxotere, Temodar, Temozolomide, Thalomid, Thalidomide, Topotecan Hydrochloride, Trastuzumab, Trisenox, Vectibix, Velcade, Vidaza, Vorinostat, Xeloda, Zoledronic Acid, Zolinza, Zometa, doxorubicin, adriamycin, bleomycin, daunorubicin, dactinomycin, epirubicin, idarubicin, mitoxantrone, valrubicin, hydroxyurea, mitomycin, fluorouracil, 5-FU, methotrexate, floxuridine, interferon alpha-2b, glutamic acid, plicamycin, 6-thioguanine, aminopterin, pemetrexed, raltitrexed, cladribine, clofarabine, fludarabine, mercaptopurine, pentostatin, capecitabine, cytarabine, carmustine, BCNU, lomustine, CCNU, cytosine arabinoside, cyclophosphamide, estramustine, hydroxyurea, procarbazine, mitomycin, busulfan, medroxyprogesterone, estramustine phosphate sodium, ethinyl estradiol, estradiol, megestrol acetate, methyltestosterone, diethylstilbestrol diphosphate, chlorotrianisene, testolactone, mephalen, mechlorethamine, chlorambucil, chlormethine, ifosfamide, bethamethasone sodium phosphate, dicarbazine, asparaginase, mitotane, vincristine, vinblastine, etoposide, teniposide, Topotecan, IFN-gamma, irinotecan, campto, irinotecan analogs, carmustine, fotemustine, lomustine, streptozocin, carboplatin, oxaliplatin, BBR3464, busulfan, dacarbazine, mechlorethamine, procarbazine, thioTEPA, uramustine, vindesine, vinorelbine, alemtuzumab, tositumomab, methyl aminolevulinate, porfimer, verteporfin, lapatinib, nilotinib, vandetanib, ZD6474, alitretinoin, altretamine, amsacrine, anagrelide, denileukin diftitox, estramustine, hydroxycarbamide, masoprocol, mitotane, and tretinoin.
