The present invention provides a novel PSMA binding antibody termed 10B3 and pharmaceutical and diagnostic uses of the antibody 10B3. The PSMA antibody 10B3 does not cross-compete with the state of the art PMSA binding antibody J591 and has a reduced induction of antigen shift compared to J591 and a unique reactivity with squamous cell carcinoma (SCC) cells of different origin.

Disclosed are immunotherapeutic compositions and the concurrent use of combinations of such compositions for the improved induction of therapeutic immune responses and/or for the prevention, amelioration and/or treatment of disease, including, but not limited to, cancer and infectious disease.

The present invention relates to novel recombinant fusion proteins, such as human antibody-based molecules called Vaccibodies, which are able to trigger both a T cell- and B cell immune response. The present invention also relates to a method of treating a cancer or an infectious disease by means of these specific fusion proteins.

Disclosed herein are compositions, uses, and methods for treatment of prostate cancers. In one aspect, disclosed herein is a composition or medical preparation comprising at least one RNA, wherein the at least one RNA encodes the following amino acid sequences: (i) an amino acid sequence comprising Kallikrein-2 (KLK2), an immunogenic variant thereof, or an immunogenic fragment of the KLK2 or the immunogenic variant thereof; (ii) an amino acid sequence comprising Prostate Specific Antigen (PSA), an immunogenic variant thereof, or an immunogenic fragment of the PSA or the immunogenic variant thereof; (iii) an amino acid sequence comprising Prostatic Acid Phosphatase (PAP), an immunogenic variant thereof, or an immunogenic fragment of the PAP or the immunogenic variant thereof; (iv) an amino acid sequence comprising Homeobox B13 (HOXB13), an immunogenic variant thereof, or an immunogenic fragment of the HOXB13 or the immunogenic variant thereof; and (v) an amino acid sequence comprising NK3 Homeobox 1 (NKX3-1), an immunogenic variant thereof, or an immunogenic fragment of the NKX3-1 or the immunogenic variant thereof.

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 a chimeric cytokine receptor (CCR) comprising: (i) an exodomain which binds to a ligand selected from a tumour secreted factor, a chemokinc and a cell-surface antigen; and (ii) a cytokine receptor cndodomain.

Disclosed herein are compositions comprising use of compositions comprising a live attenuated recombinant Listeria strain comprising a fusion protein of a truncated listeriolysin O (LLO) protein, a truncated ActA protein, or a PEST amino acid sequence fused to a heterologous antigen, including a tumor-associated antigen, wherein the compositions further comprise or are co-administered with an antibody or fragment thereof. Also disclosed are combination therapies comprising use of these compositions comprising live attenuated recombinant Listeria strains, in conjunction with an antibody or fragment thereof for use in treating, protecting against, and/or inducing an immune response against a tumor, especially wherein the treating, protection against and/or inducing an immune response increases percent survival in a subject.

The invention pertains to a method for treating a cancer which expresses PRAME using T cells which recognize specific peptide epitopes of PRAME, to a method for producing T cells that target cancer cells expressing PRAME, the peptide epitopes of PRAME themselves and to compositions and methods of treatment using these peptides.

In various embodiments methods of producing a cell population enriched for CLEC9A+ dendritic cells are provided where the methods involve culturing stem cells and/or progenitor cells in a cell culture comprising culture medium, a notch ligand, stem cell factor (SCF), FLT3 ligand (FLT3L); thrombopoietin (TPO); and IL-3 and/or GMCSF.

Disclosed herein is a method for treating a subject having, or at risk of having, a cancer, comprising administering to the subject a therapeutically effective amount of a tumor membrane vesicle (TMV) and a metformin. In some embodiments, the TMV comprises a B7-1 and/or IL-12 molecule anchored to a lipid membrane (e.g., by a GPI anchor). In some embodiments, the methods can further comprise administering an immune checkpoint inhibitor. The methods are useful for reducing tumor size and metastasis, and in improving anti-tumor immune responses.
