Provided herein are fumaric-containing compounds, compositions comprising the same and methods for using such compounds for increasing the capacity of an interferon-sensitive virus to infect, transduce, grow or replicate in a cell or spread within one or more tissues. Also provided are methods for increasing the capacity of an interferon-sensitive virus to produce a virus-encoded transgene from a cell, by administering the compounds and compositions.

Compositions and methods for enhancing production, growth, spread, or oncolytic and immunotherapeutic efficacy of interferon-sensitive viruses

Provided are compounds of Formula III that enhance the efficacy of viruses by increasing spread of the virus in cells, increasing the titer of virus in cells, or increasing the antigen expression from a virus, gene or trans-gene expression from a virus, or virus protein expression in cells. Other uses, compositions and methods of using same are also provided.

Compositions and methods for viral sensitization

Provided herein are fumaric and maleic acid-containing compounds, compositions comprising the same and methods for using such compounds to enhance production, growth, spread or titer of interferon-sensitive viruses in cells, particularly cancer and tumor cells. Also provided are methods of treating tumors or cancers in a subject by administering the compounds and compositions.

Provided herein are methods for enhancing infection, growth, spread, or titer of an oncolytic RNA virus in a cancer or tumor cell; enhancing the oncolytic activity, cytokine-induced cell death activity, and/or cytotoxic activity of an oncolytic RNA virus in a cancer or tumor cell; upregulating cytokine response to, and/or enhancing the immunotherapeutic activity of an oncolytic RNA virus in a cancer or tumor cell; and/or treating a tumor or cancer in a subject in need thereof. Such methods employ a vanadium-containing compound, administered to the cancer or tumor cells before, after, or concurrently with infection of the cancer or tumor cells with the oncolytic RNA virus. Related compositions, uses, and kits therefor are also provided. Methods for producing RNA viruses, RNA virus-based cancer vaccines, and RNA virus-based cancer gene therapy vectors are also provided.

Compositions and methods for enhancing growth, spread, and oncolytic and immunotherapeutic efficacy of oncolytic RNA viruses

Provided are compounds of Formula (II) that enhance the efficacy of viruses by increasing spread of the virus in cells, increasing the titer of virus in cells, or increasing the antigen expression from a virus, gene or trans-gene expression from a virus, or virus protein expression in cells. Other uses, compositions and methods of using same are also provided. 

Described herein is a method of enhancing virus replication in permissive cells that express a receptor to FGF2 protein. The method includes administering FGF2 protein or a functional variant thereof and the virus to the permissive cells. An oncolytic virus having a genome that includes an open reading frame that encodes FGF2 protein or a functional variant thereof is also described.

Compositions and methods for enhancing virus replication

A vaccination method is provided. The method comprises administering to a mammal a histone deacytelase inhibitor in conjunction with a vaccine that expresses an antigen to which the mammal has a pre-existing immunity.

Method of vaccination comprising a histone deacetylase inhibitor

Provided are viral sensitizing compounds that enhance the efficacy of viruses by increasing spread of the virus in cells, increasing the titer of virus in cells, or increasing the cytotoxicity of virus to cells. Other uses, compositions and methods of using same are also provided.
