The present disclosure relates to replication-competent controlled herpesviruses whose transient replication in a desired inoculation site region of a subject can be activated by the delivery of an appropriate heat dose to the inoculation site region. In related recombinant viruses, activation requires delivery of a heat dose in the presence in the inoculation site region of an effective concentration of a small-molecule regulator. The viruses are further engineered to be capable of replicating efficiently in the desired inoculation site region but essentially not in nerve ganglia and other nerve cells.

The present disclosure provides recombinant nucleic acids comprising one or more polynucleotides encoding an immunomodulatory polypeptide (e.g., a pro-inflammatory cytokine such as a human IL-2 or IL-12 polypeptide); viruses comprising the recombinant nucleic acids; compositions and formulations comprising the recombinant nucleic acids and/or viruses; methods of their use (e.g., for the treatment of cancer, such as lung cancer); and articles of manufacture or kits thereof.

The present invention provides vaccines for treating or preventing a herpes simplex virus infection and methods of using and making the vaccine. Further provided are recombinant herpes simplex virus genomes, recombinant viruses, and immunogenic compositions.

The present disclosure provides recombinant nucleic acids comprising one or more polynucleotides encoding an immunomodulatory polypeptide (e.g., a pro-inflammatory cytokine such as a human IL-2 or IL-12 polypeptide); viruses comprising the recombinant nucleic acids; compositions and formulations comprising the recombinant nucleic acids and/or viruses; methods of their use (e.g., for the treatment of cancer, such as lung cancer); and articles of manufacture or kits thereof.

Disclosed herein are high transducing replication defective herpes simplex virus (HSV) vectors of McKrae strain.

Recombinant oncolytic viruses that produce and secrete novel immunomodulatory fusion proteins are described. The fusion proteins encode a single chain variable fragment antibody (ScFv) that specifically binds PD-1 OR PD-L1 fused via an antibody Fc region to the ectodomain of the TGFβ receptor II (TGFβRII.sub.ecto). The immunomodulatory fusion proteins have dual function: blocking inhibitory pathways mediated by PD-1/PD-L1 and blocking the immune-dampening activity of TGFβ. In addition, dual gene oncolytic herpes simplex viruses (HSVs) are provided that include, in addition to a gene encoding an ScFv-Fc-TGFβRII.sub.ecto fusion protein, a gene encoding IL12, a T cell stimulatory factor.

The present disclosure provides recombinant nucleic acids comprising one or more polynucleotides encoding an immunomodulatory polypeptide (e.g., a pro-inflammatory cytokine such as a human IL-2 or IL-12 polypeptide); viruses comprising the recombinant nucleic acids; compositions and formulations comprising the recombinant nucleic acids and/or viruses; methods of their use (e.g., for the treatment of cancer, such as lung cancer); and articles of manufacture or kits thereof.

The present invention provides vaccines for treating or preventing a herpes simplex virus infection and methods of using and making the vaccine. Further provided are recombinant herpes simplex virus genomes, recombinant viruses, and immunogenic compositions.

The present invention is directed to Herpes simplex-2 viruses that may be used in vaccines to immunize patients against genital herpes.

Methods for passive transfer of immunity using recombinant herpes simplex virus 2 (HSV-2) vaccine vectors, virions thereof, compositions and vaccines comprising such.
