Compositions and methods are provided for preventing or treating neoplastic disease in a mammalian subject. A composition is provided which comprises an enriched immune cell population reactive to a human endogenous retrovirus type E antigen on a tumor cell. A method of treating a neoplastic disease in a mammalian subject is provided which comprises administering to a mammalian subject a composition comprising an enriched immune cell population reactive to a human endogenous retrovirus type E antigen, in an amount effective to reduce or eliminate the neoplastic disease or to prevent its occurrence or recurrence.

Provided are a novel fully human antibody for human B7H3, a chimeric antigen receptor, and uses thereof; also provided are a novel fully human anti-human B7H3 antibody, a chimeric antigen receptor containing the antibody, and genetically engineered cells expressing the receptor and the antibody. It has been verified by experiments that CAR-T, CAR-NK and CAR-iNKT cells targeting B7H3 prepared on the basis of the present chimeric antigen receptor have relatively strong proliferation ability, cytokine release ability and tumor cell killing ability, and can effectively eliminate tumor cells.

The present invention relates to augmenting the effects of adoptive T cell therapy, such as TVAX Immunotherapy, using adjunct treatment with an oncolytic virus, such as a vaccinia virus, to treat various types of cancer or other proliferative disorders. Immunomodulatory compounds can be used to further augment to effects of the therapy.

This invention provides methods to prepare and use immunostimulatory cells for enhancing an immune response. The invention provides a method for preparing mature dendritic cells (DCs), comprising the sequential steps of: (a) signaling isolated immature dendritic cells (iDCs) with a first signal comprising an interferon gamma receptor (IFN-R) agonist and/or a tumor necrosis factor alpha receptor (TNF-R) agonist to produce signaled dendritic cells; and (b) signaling said signaled dendritic cells with a second transient signal comprising an effective amount of a CD40 agonist to produce CCR7.sup.+ mature dendritic cells. Also provided by this invention are enriched populations of dendritic cells prepared by the methods of the invention. Such dendritic cells have enhanced immunostimulatory properties and increased IL-12 secretion and/or decreased IL-10 secretion. CD40 signaling can be initiated by one or more of polypeptide translated from an exogenous polynucleotide encoding CD40L (e.g., mRNA or DNA), an agonistic antibody to CD40 receptor or by CD40 ligand polypeptide. The enriched populations can be further modified by the administration of an immunogen to the DC. The DC will take up and process the immunogen on its cell surface.

This invention provides an anti-cancer immunogenic agent(s) (e.g. vaccines) that elicit an immune response specifically directed against renal cell cancers expressing a G250 antigenic marker. Preferred immunogenic agents comprise a chimeric molecule comprising a kidney cancer specific antigen (G250) attached to a granulocyte-macrophage colony stimulating factor (GM-CSF). The agents are useful in a wide variety of treatment modalities including, but not limited to protein vaccination, DNA vaccination, and adoptive immunotherapy.

This invention relates to the field of therapeutics. Most specifically invention provides methods of generating in vitro engineered immune cells conditionally expressing interleukin-12 (IL-12) and one or more immunomodulators under the control of a gene expression modulation system in the presence of activating ligand and uses for therapeutic purposes in animals.

Materials and methods for producing genome-edited cells engineered to express a chimeric antigen receptor (CAR) construct on the cell surface, and materials and methods for genome editing to modulate the expression, function, or activity of one or more immuno-oncology related genes in a cell, and materials and methods for treating a patient using the genome-edited engineered cells.

Compounds, compositions, and methods for use in inhibiting the E3 enzyme Cbl-b in the ubiquitin proteasome pathway are disclosed. The compounds, compositions, and methods can be used to modulate the immune system, to treat diseases amenable to immune system modulation, and for treatment of cells in vivo, in vitro, or ex vivo. Also disclosed are pharmaceutical compositions comprising a Cbl-b inhibitor and a cancer vaccine, as well as methods for treating cancer using a Cbl-b inhibitor and a cancer vaccine; and pharmaceutical compositions comprising a Cbl-b inhibitor and an oncolytic virus, as well as methods for treating cancer using a Cbl-b inhibitor and an oncolytic virus.

Described herein are compositions of matter and methods for treating cancer. The compositions comprise altered human telomerase polypeptides containing T cell epitopes that have been altered to increase immunogenicity. The methods comprise administration of the polypeptides or nucleic acids, such as DNA or RNA encoding the polypeptides, to individuals afflicted with, or at risk of, developing cancer.
