Some embodiments of the present disclosure are directed to methods that include delivering to a subject a nucleic acid encoding an antigen, wherein the nucleic acid is delivered via a tumor-selective vehicle or via intratumoral injection, and delivering to the subject an immune cell expressing a receptor that binds to the antigen.

Cancer is treated using coordinated treatment regimens that uses various compounds and compositions that drive a tumor from the escape phase of cancer immunoediting to the elimination and equilibrium phase of cancer immunoediting.

The present invention relates to a nucleic acid sequence, comprising or coding for a coding region, encoding at least one peptide or protein comprising a tumour antigen or a fragment, variant or derivative thereof, at least one histone stem-loop and a poly(A) sequence or a polyadenylation signal. Furthermore the present invention provides the use of the nucleic acid for increasing the expression of said encoded peptide or protein. It also discloses its use for the preparation of a pharmaceutical composition, especially a vaccine, e.g. for use in the treatment of cancer or tumour diseases. The present invention further describes a method for increasing the expression of a peptide or protein comprising a tumour antigen or a fragment, variant or derivative thereof, using the nucleic acid comprising or coding for a histone stem-loop and a poly(A) sequence or a polyadenylation signal.

The invention provides Brachyury deletion mutant polypeptides, nucleic acids encoding the polypeptides, non-yeast vectors comprising the nucleic acids, non-yeast cells, and methods of use.

Provided are isolated antibodies and antigen-binding fragments thereof that specifically bind CEACAM1, including the IgV domain of CEACAM1, as well as pharmaceutical formulations, kits, and methods of use thereof.

A cancer vaccine is provided including a recombinant nucleic acid encoding a self-activating chimeric signaling protein, and especially chimeric TNF family ligand-receptor proteins, and a tumor-associated antigen. In a preferred embodiment, the cancer vaccine may further include a nucleic acid segment encoding an IL-15 superagonist. In addition, the cancer vaccine can be co-administered with a genetically modified bacteria or yeast as an adjuvant to increase the payload expression of the cancer vaccine. Advantageously, cells expressing such combination of molecules will enhance immune reaction against tumor cells. Compositions and methods are presented that allow for an enhanced immune response against a vaccine composition, and particularly a recombinant adenoviral expression system that is used as a therapeutic agent. Most preferably, immune therapeutics are administered such that a protein or nucleotide are co-located with a therapeutic antigen, preferably via co-expression of the protein.

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 present invention relates to a recombinant virus of the family Paramyxoviridae comprising an expressible polynucleotide encoding at least one of (i) a tumor antigen, (ii) a fragment of a tumor antigen, and (iii) a variant of (i) or (ii). The present invention further relates to a polynucleotide encoding said recombinant virus of the family Paramyxoviridae and to a host cell comprising said recombinant virus of the family Paramyxoviridae and/or said polynucleotide encoding said recombinant virus of the family Paramyxoviridae. Moreover, the present invention relates to a method for activating immune cells with antitumor activity in a sample comprising cancer cells and to further means, methods, and uses related to the present invention.

The present invention provides an immune enhancer comprising at least an interferon and a granulocyte-macrophage colony-stimulating factor, and an immunotherapeutic pharmaceutical composition comprising at least an antigen and the above-mentioned immune enhancers. The present invention further discloses a preparation method of the immunotherapeutic pharmaceutical composition, the use of the immune enhancer and the immunotherapeutic pharmaceutical composition. The immune enhancer can be applied to disease and tumor treatments caused by viruses, bacteria, and other microorganisms.

Methods for generating immune responses using adenovirus vectors that allow multiple vaccinations with the same adenovirus vector and vaccinations in individuals with preexisting immunity to adenovirus are provided.
