Abstract: Methods for treating cell proliferative disorders by administering virus to proliferating cells having an activated Ras-pathway are disclosed. The virus is administered so that it ultimately directly contacts proliferating cells having an activated Ras-pathway. Proliferative disorders include but are not limited to neoplasms. The virus is selected from modified adenovirus, modified HSV, modified vaccinia virus and modified parapoxvirus orf virus. Also disclosed are methods for treating cell proliferative disorders by further administering a immunosuppressive agent.
Abstract: This invention refers to the use of an adenovirus for cancer treatment, being this adenovirus defective in its virus-associated (VA) RNAs. Said adenovirus has a mutation in the VAI or VAII gene sequence or both. This adenovirus may also have mutations in the sequences controlling expression of the VA RNAs.
Abstract: Methods for treating proliferative disorders, by administering reovirus to a Ras-mediated proliferative disorder, are disclosed. The reovirus is administered so that it ultimately directly contacts ras-mediated proliferating cells. Proliferative disorders include but are not limited to neoplasms. Human reovirus, non-human mammalian reovirus, and/or avian reovirus can be used. If the reovirus is human reovirus, serotype 1 (e.g., strain Lang), serotype 2 (e.g., strain Jones), serotype 3 (e.g., strain Dearing or strain Abney), as well as other serotypes or strains of reovirus can be used. Combinations of more than one type and/or strain of reovirus can be used, as can reovirus from different species of animal. Either solid neoplasms or hematopoietic neoplasms can be treated.

Abstract: Provided herein is a mutant reovirus (e.g., a genetically-engineered ISVP). Compositions including mutant reoviruses and methods of using such mutant reoviruses are also provided.
Abstract: The present invention pertains to methods for preventing reovirus recognition in the treatment of cellular proliferative disorders, and particularly ras-mediated cellular proliferative disorders, in mammals. The method comprises suppressing or otherwise inhibiting the immune system of the mammal and, concurrently or subsequently, administering to the proliferating cells an effective amount of one or more reoviruses under conditions which result in substantial lysis of the proliferating cells. The methods may include the selective removal of immune constituents that may interfere with the systemic delivery of the virus; preventing reovirus recognition by the host immune system; and removal of the virus from an immune suppressed or immune incompetent host following treatment with reovirus. Alternatively, reovirus may be administered to a mammal with a diminished immune response system under conditions which result in substantial lysis of the proliferating cells.
Abstract: Reovirus can be used to selectively remove ras-mediated neoplastic cells from a cellular composition. It is of particular interest to purge autographs which may contain neoplastic cells with reovirus before transplanting the autographs back into the recipient, thereby reducing the risk of introducing or reintroducing neoplastic cells into the recipient.

Abstract: The present invention provides a method for reducing pain associated with neoplasms in a mammal, comprising administering an effective amount of one or more oncolytic viruses. Preferably, the mammal also receives an analgesic, and the amount of analgesic required by the mammal is reduced when the oncolytic virus is administered. The oncolytic virus is preferably reovirus. The mammal may be additionally subject to other therapies, such as chemotherapy, immunotherapy, hormonal and/or radiation therapy.

Abstract: The present invention pertains to methods for preventing reovirus recognition in the treatment of cellular proliferative disorders, and particularly ras-mediated cellular proliferative disorders, in mammals. The mammal may be selected from dogs, cats, sheep, goats, cattle, horses, pigs, mice, humans and non-human primates. The method comprises suppressing or otherwise inhibiting the immune system of the mammal and, concurrently or subsequently, administering to the proliferating cells an effective amount of one or more reoviruses under conditions which result in substantial lysis of the proliferating cells. In particular, the methods provide for reovirus treatment of immunosuppressed or immuno-deficient mammals to treat the proliferative disorders. Immunosuppression, immunoinhibition or otherwise inducing an immunodeficient state in a mammal renders the reovirus more effective.

Abstract: The present invention relates to a method for removing neoplastic cells from a mixed cellular composition, which is outside of a living organism, by using a virus which selectively infect and kill neoplastic cell. A variety of viruses can be used in this method to remove neoplastic cells for different purposes, for example, to purge hematopoietic stem cells prior to transplantation. Also provided are compositions prepared according to this method, and kits comprising a combination of viruses which are useful in this invention.
