The present disclosure provides compositions and methods for boosting, augmenting or enhancing the efficacy of the adoptive cellular immunotherapy by using modified T cells expressing an antigen binding protein in conjunction with modified cells (such as hematopoietic progenitor cells, modified human immune system cells or a combination thereof) expressing the antigen specifically bound by the antigen binding protein of the modified T cells.

The invention relates to a composition which induces, in a host, a cytotoxic cell response directed against cells expressing an antigen, in particular tumour cells, and which comprises red blood cells containing said antigen. These red blood cells may be in the form of an immune complex with an immunoglobulin, in particular IgG, which recognizes an epitope at the surface of the red blood cells, and/or be heat-treated or chemically treated so as to promote phagocytosis of said red blood cells by dendritic cells. As a variant, the red blood cells may be xenogenic red blood cells. The invention also relates to a therapeutic especially anti-tumour vaccine containing such a composition.

Vector compositions comprising a myeloproliferative sarcoma virus enhancer, negative control region deleted, dl587rev primer-binding site substituted (MND) promoter operably linked to a chimeric antigen receptor (CAR) are provided.

The invention provides compositions and methods for treating diseases associated with expression of a cancer associated antigen as described herein. The invention also relates to chimeric antigen receptor (CAR) specific to a cancer associated antigen as described herein, vectors encoding the same, and recombinant T cells comprising the CARs of the present invention. The invention also includes methods of administering a genetically modified T cell expressing a CAR that comprises an antigen binding domain that binds to a cancer associated antigen as described herein.

Provided herein are methods of treating cancer and/or augmenting a microbiome in a subject who has a tumor.

A method is presented for screening cells that produce allogeneic autophagosome enriched compositions able to induce expression of a selective marker on a subpopulation of peripheral blood mononuclear cells, the method comprising contacting a cell with a proteasome inhibitor, contacting the cell with a lysosome inhibitor, harvesting the resulting autophagosomes, determining a molecular signature of the harvested autophagosomes, and selecting cells that divert one or more Toll-like receptor agonist and/or one or more molecular chaperones to the harvested autophagosomes. By screening for cells that divert one or more Toll-like receptor agonist and/or one or more molecular chaperones to the harvested autophagosomes, enriched populations of autophagosomes may be generated which may illicit a specific immune response against numerous cancer types. In this way, an allogeneic, off-the-shelf cancer vaccine may be produced and made available to be administered in order to stimulate a targeted immune response in patients bearing different tumor types.

The present invention relates to an antigen composition comprising at least one mesothelioma cancer cell associated antigen and a pharmaceutically acceptable carrier for use in the treatment of cancer, in particular mesothelioma, wherein dendritic cells are loaded with said antigen composition and wherein said loaded dendritic cells are administered in combination with one or more checkpoint inhibitors, to patients. The present invention also relates to an antigen composition comprising at least two mesothelioma cancer cell associated antigens and a pharmaceutically acceptable carrier. The present invention further relates to an antigen composition comprising at least two mesothelioma cancer cell associated antigens and a pharmaceutically acceptable carrier, for use as a pharmaceutical, in particular for use in the treatment of mesothelioma.
