Methods of vaccinating, immunizing and/or treating a subject against a herpes simplex virus infection or a disease caused by a herpes simplex virus infection comprise administering to the subject an effective amount of a HSV-2 single-cycle virus and an effective amount of a recombinant HSV-2 glycoprotein D, wherein the HSV-2 single-cycle virus comprises HSV-2 having a deletion of glycoprotein D-encoding gene in the genome and the HSV-2 is phenotypically complemented with an HSV-1 glycoprotein D on a lipid bilayer of the HSV-2.

Provided herein is a powder comprising a live, attenuated virus, recombinant human serum albumin (rHSA), a sugar other than lactose, a sugar alcohol, a source of phosphate, a source of chloride, wherein the composition is substantially free of lactose, gelatin, antibiotic, and free amino acids. In exemplary aspects, the powder is a lyophilizate of a liquid composition. Related liquid compositions, methods of preparing an oncolytic virus for administration and methods of treating melanoma are also provided herein.

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.

Provided herein are compositions and methods for vaccination and research applications. In particular, provided herein are non-neuroinvasive herpesviruses and alpha herpesviruses and uses thereof.

The disclosure provides a non-natural herpes simplex virus (“HSV”), compositions comprising, or alternatively consisting essentially of, or yet further consisting of the HSV, and methods of producing the HSV, or infecting a cell with the HSV. Also provided herein are methods of treating cancer or inhibiting the growth or metastasis of cancer cell in a subject in need thereof.

The present disclosure provides a bispecific single-chain antibody, recombinant oncolytic virus for expressing same and virus composition. The antibody named BiTEs-PD-L1 is a bispecific antibody capable of simultaneously binding CD3 and PD-L1 on the surfaces of tumor cells, and it can effectively activate T cells and guide T cells to kill tumor cells. The oncolytic virus oHSV2-BiTEs-PD-L1 is further developed by utilizing the BiTEs-PD-L1, it can reduce frequency and dosage of the administration. The present disclosure also confirmed several virus compositions with excellent antitumor effect.

The disclosure provides oncolytic herpes virus comprising a heterologous gene encoding E-cadherin. The disclosure further provides pharmaceutical compositions that comprise such oncolytic herpes virus, and methods of treatment using such oncolytic herpes virus.

This invention relates to herpes simplex virus (HSV) based vectors for delivering transgenes (e.g., a therapeutic gene) which are more resistant to neutralization, phagocytosis, and NK cells by immune systems, and methods for their preparation and treatment of disorders and diseases (such as those related to gene expression) with them. In one embodiment, the HSV vectors are prepared by treatment in immune sera that contain a high level of anti-HSV antibodies. The HSV vectors may include an extracellular CD47 domain inserted into the N-terminus of a glycoprotein in order to inhibit phagocyte activity, and the absence of gE for evading NK cells.

A recombinant herpes virus showing high antitumor activity is provided. In particular, a recombinant herpes simplex virus that expresses an ICP6 gene under control of a tumor-specific promoter or tissue-specific promoter on the genome of the virus is provided.

Malignant tumors that are resistant to conventional therapies represent significant therapeutic challenges. An embodiment of the present invention provides a regulatable fusogenic oncolytic herpes simplex virus-1 that is more effective at selective killing target cells, such as tumor cells. In various embodiments presented herein, the oncolytic virus described herein is suitable for treatment of solid tumors, as well as other cancers.
