Abstract: The present invention provides an anti-cancer vaccine comprising: (i) at least one peptide comprising the amino acid sequence of a neoantigen encoded by a mutant homologous recombination (HR) DNA repair gene selected from the group: BRCA1, BRCA2, PALB2, CDK12, RAD51B, RAD51C and RAD51D, wherein the mutant gene comprises a reversion mutation; and/or (ii) at least one polynucleotide encoding the at least one peptide of (i). Also provided are engineered T cells that recognise said neoantigen. Related methods and medical uses of the vaccine and/or engineered T cell are provided, including for the treatment of cancers, such as homologous recombination (HR) deficient cancers that acquire PARP inhibitor resistance or platinum resistance by development of reversion mutations in an HR DNA repair gene selected from the group: BRCA1, BRCA2, PALB2, CDK12, RAD51B, RAD51C and RAD51D.

Abstract: This document provides methods and materials related to treating cancer. For example, methods and materials for using nucleic acid libraries to treat cancer are provided.

Abstract: This document provides methods and materials for treating cancer. For example, methods and materials for treating cancer using combinations of antigens are provided. For example, VSV vectors designed to express a GNAQ antigen, a TYRP1 antigen, and an N-RAS antigen can be used to reduce the number of cancer cells (e.g., uveal melanoma cells) within a mammal (e.g., a human). In some cases, VSV vectors designed to express a BRAF antigen, a TOPO-11a antigen, and a YB-I antigen can be used to reduce the number of cancer cells (e.g., skin melanoma cells) within a mammal (e.g., a human). The composition can comprise less than 50 separate nucleic acid molecules.

Abstract: This document provides methods and materials for treating cancer. For example, methods and materials for identifying antigens and combinations of antigens that can be used to treat cancer as well as combinations of antigens having the ability to reduce established tumors (e.g., gliomas) within a mammal (e.g., a human) are provided.

Abstract: Disclosed is a cell which expresses a surface marker associated with a professional antigen presenting cell, and a fusogenic membrane protein, where the cell may also express at its surface a tumor cell marker. Also disclosed is a fusion hybrid formed by the fusion of a tumor cell and a professional antigen presenting cell (APC) such that the resulting fusion hybrid expresses an APC marker, a tumor cell marker, and a fusogenic membrane glycoprotein. Also disclosed are compositions comprising the cells and fusion hybrids, and methods of making and using the hybrids.
