Malignant tumors that are resistant to conventional therapies represent significant therapeutic challenges. An embodiment of the present invention provides an oncolytic virus capable of killing target cells, such as tumor cells. In various embodiments presented herein, the oncolytic viruses described herein are suitable for treatment of several types of cancer, including glioblastoma.

The present disclosure relates, in part, to pharmaceutical compositions comprising one or more polynucleotides suitable for enhancing, increasing, augmenting, and/or supplementing the levels of Collagen alpha-1 (VII) chain polypeptide and/or Lysyl hydroxylase 3 polypeptide and/or Keratin type I cytoskeletal 17 polypeptide in a subject. The present disclosure also relates, in part, to pharmaceutical compositions and methods of use for providing prophylactic, palliative, or therapeutic relief of a wound, disorder, or disease of the skin in a subject, including a subject having, or at risk of developing, one or more symptoms of epidermolysis bullosa.

Disclosed are custom HSV-1 packaging genomes for chromosomal integration into a cell line that is devoid of cis-acting HSV origins of replication (ori) and packaging sequences (pac) normally used for incorporation of the viral genome into virus particles, as well as the use of the resulting packaging cell for amplicon packaging.

Disclosed is a genetically modified oncolytic herpes simplex virus (oHISV) encoding a truncated nonsignaling variant of at least one tumor associated/specific antigen, and at least one chemokine. The expression of the truncated nonsignaling variant and the chemokine is under the control of an immediate-early gene promoter of HSV, and the truncated nonsignaling variant is expressed and presented on a tumor cell surface as a biomarker upon replication of the oHSV in the tumor cell, and the chemokine is expressed and released to induce chemotaxis of an immune cell towards the tumor cell. The genetically modified oHSV can be used in combination with CAR-T, ADC, and/or BiTE therapies.

The invention described herein provides a recombinant replication-defective virus derived from Herpesvirales order, comprising a defective ICP27 gene that impairs or otherwise does not support replication of the HSV, or a functional equivalent gene thereof; a gene-of-interest (GOI) flanked by AAV ITR sequences inserted at, within, or replacing a non-essential or replaceable essential locus of the HSV; and a coding sequence for AAV Rep and Cap proteins inserted at, within or replacing the non-essential or replaceable essential locus of the HSV. The invention also provides production cell lines for such recombinant replication-defective virus, wherein the cell lines have a coding sequence for ICP27 or a functional equivalent thereof, and wherein the coding sequence has no or minimal sequence overlap with the virus characterized by the defective ICP27 gene that impairs or otherwise does not support replication of the HSV. Methods of using such recombinant replication-defective virus and production cell lines are also provided. rAAV produced using such recombinant replication-defective virus and/or production cell lines and methods of making such rAAV are also provided.

This disclosure provides an attenuated suid herpesvirus 1 (a Pseudorabies virus) wherein the TK, gI and gE genes thereof are modified relative to a parent field strain, such that the resultant virus is safe and effective for use as a live vaccine that protects swine animals from challenge with a virulent Pseudorabies virus.

The present invention relates to an oncolytic virus which is, or is derived from, a clinical isolate which has been selected by comparing the abilities of a panel of three or more clinical isolates of the same viral species to kill tumor cells of two or more tumor cell lines in vitro and selecting a clinical isolate which is capable of killing cells of two or more tumor cell lines more rapidly and/or at a lower dose in vitro than one or more of the other clinical isolates in the panel.

The present invention relates to compositions and methods for treating cancer. More specifically, the present invention relates to compositions of engineered oncolytic viruses for administration to a subject with cancer that specifically lyse tumor cells and actively target tumor cells and cell debris to antigen presenting cells, in order to generate anti-tumor immunity.

Provided are a new herpes simplex virus type I, a genetically modified herpes simplex virus, a composition containing the virus, a host cell and a cell culture, and the use of the virus in the treatment of diseases.

The present invention relates to non-laboratory virus strains, for example of herpes viruses such as HSV, with improved oncolytic and/or gene delivery capabilities as compared to laboratory virus strains.
