The present invention relates to a technology and method of priming of an immune response using invariant chain linked antigen, when these are used to prime a subsequent booster immunization using any suitable vacci.

Hematopoeitic stem/progenitor cells (HSPC) and/or non-T effector cells are modified to express an extracellular component including a tag cassette. The tag cassette can be used to activate, promote proliferation of, detect, enrich, isolate, track, deplete and/or eliminate modified cells. The cells can also be modified to express a binding domain.

The compositions and methods are described for generating an immune response to a tumor associated antigen (TAA) such as MUC-1, survivin, cyclin B1, HBV, or HPV. The compositions and methods described herein relate to a modified vaccinia Ankara (MVA) vector encoding one or more viral antigens for generating a protective immune response to the tumor associated antigen in the subject to which the vector is administered and optionally, boosting the immune response by administering a tumor associated antigen. The compositions and methods of the present invention are useful both prophylactically and therapeutically and may be used to prevent and/or treat neoplasms and associated diseases.

The disclosure relates to methods of culturing and expanding CD4+ and/or CD8+ T cells in culture. In some embodiments, the methods include expanding, proliferating and storing lymphocytes in tissue culture by exposing the lymphocytes to a combination of cytokines and/or nucleic acids expressing cytokines or functional fragments or variants thereof. The disclosure further relates to methods of generating and manufacturing CD4+ and/or CD8+ T cells that are specific to one or a plurality of viral antigens.

The present invention provides a complex for use in the prevention and/or treatment of cancer, the complex comprising a) a cell penetrating peptide, b) at least one antigen or antigenic epitope, and c) at least one TLR peptide agonist, wherein the components a)-c) are covalently linked. In particular, compositions for use in the prevention and/or treatment of cancer, such as a pharmaceutical compositions and vaccines are provided.

The present invention provides improved LAMP Constructs comprising specific fragments of the LAMP lumenal domain to deliver antigens to immune cells for enhanced processing. These LAMP Constructs can be used for the treatment of disease and in particular, allergies, infectious disease, diabetes, hyperproliferative disorders and/or cancer. The improved LAMP Constructs allow for presentation of properly configured three dimensional epitopes for production of an immune response when administered to a subject. The improved LAMP Constructs can be multivalent molecules, and/or can be provided as part of a multivalent vaccine containing two or more LAMP Constructs. The improved LAMP Constructs as described herein can also be used to generate antibodies when administered to a non-human vertebrate.

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.

The present application relates generally to methods for treating tumors, and in particular to methods for improving the efficacy of a survivin therapeutic in the treatment of tumors by improving survivin specific T cell infiltration in tumor.

The present invention concerns compositions and methods related to approaches to render ineffective Th1 T cells resistant to the inhibitory cytokine milieu present in a cancer microenvironment. In particular embodiments, tumor-specific T cells are modified to employ a chimeric receptor that binds inhibitory/suppressive cytokines and converts their intracellular consequences to a Th1 immunostimulaotyr/activating signal. In specific embodiments, the T cells employ a chimeric antigen receptor having exodomains for IL10, IL13 and/or IL4 fused with the signal transducing endodomains for IL2 and/or IL7.

The present disclosure provides methods for treating a progressive ovarian cancer using an allogeneic leukemia-derived cell. Also provided are immunogenic compositions comprising an allogeneic leukemia-derived cell, and pharmaceutical compositions and formulations thereof.
