The present application discloses a method of treating cancer, including administering to a person suffering from cancer or in remission from cancer, an antigen presenting cell loaded with an immunogenic CD4 T cell activating antigen and a CD8 T cell activating neoantigen specific for the cancer.

An immunogenic composition comprising at least one Norovirus antigen and at least one adjuvant which is at least one B subunit of an AB.sub.5 toxin such as cholera toxin subunit B (CTB) or the B subunit of heat-labile E. coli exotoxin LT (LTB).

The present disclosure relates to methods and compositions for inducing an immune response in a subject comprising providing to the subject a peptide or protein vaccine and a binding agent, such as a bispecific antibody, binding to PD-L1 and CD137, such as human PD-L1 and human CD137, e.g., by co-administering to the subject a peptide or protein used for vaccination or a polynucleotide, in particular RNA, encoding a peptide or protein used for vaccination, and a binding agent binding to PD-L1 and CD137 or a polynucleotide, in particular RNA, encoding a binding agent binding to PD-L1 and CD137. The present disclosure further relates to medical preparations useful in the methods disclosed herein.

The present disclosure provides T-cell modulatory multimeric polypeptides (T-Cell-MMPs) conjugated to a coronavirus epitope and comprising at least one immunomodulatory polypeptide (“MOD”) that may be selected to exhibit reduced binding affinity to a cognate co-immunomodulatory polypeptide (“Co-MOD”). By presenting the coronavirus epitope and MOD to a T-cell, the T-Cell-MMP-coronavirus epitope conjugates are useful for modulating the activity (e.g., increasing proliferation or cytotoxic activity) of T-cells specific to the coronavirus peptide in an epitope selective/specific manner, and accordingly, for treating individuals with a coronavirus infection.

The present invention relates to antigen-based immunotherapy, in particular cancer immunotherapy. In particular, the present invention provides antigenic peptides, which are distinct from, but have amino acid similarity to, especially share the same core sequence with epitopes of human tumor antigens. The present invention further provides immunogenic compounds, nanoparticles, cells and pharmaceutical compositions comprising such antigenic peptides and nucleic acids encoding such antigenic peptides.

The present invention relates to RNA decorated particles such as RNA decorated lipid particles, preferably to RNA decorated liposomes. Further, the present invention relates to a pharmaceutical composition comprising RNA decorated particles such as RNA decorated lipid particles, preferably RNA decorated liposomes. Said pharmaceutical composition is useful for inducing an immune response. It is also useful in a prophylactic and/or therapeutic treatment of a disease involving an antigen. Furthermore, the present invention relates to a method for producing the RNA decorated particles such as RNA decorated lipid particles, preferably RNA decorated liposomes.

The present invention relates to a vaccine/inhibitor combination comprising an RNA vaccine comprising at least one RNA comprising at least one open reading frame (ORF) coding for at least one antigen and a composition comprising at least one PD-1 pathway inhibitor, preferably directed against PD-1 receptor or its ligands PD-L1 and PD-L2. The present invention furthermore relates to a pharmaceutical composition and a kit of parts comprising the components of such a vaccine/inhibitor combination. Additionally the present invention relates to medical use of such a vaccine/inhibitor combination, the pharmaceutical composition and the kit of parts comprising such a vaccine/inhibitor combination, particularly for the prevention or treatment of tumor or cancer diseases or infectious diseases. Furthermore, the present invention relates to the use of an RNA vaccine in therapy in combination with a PD-1 pathway inhibitor and to the use of a PD-1 pathway inhibitor in therapy in combination with an RNA vaccine.

The invention provides an immunoconjugate comprising an antibody construct which includes an antigen binding domain and an Fc domain, an adjuvant moiety, and a linker, wherein each adjuvant moiety is covalently bonded to the antibody via the linker. Methods for treating cancer with the immunoconjugates of the invention are also described.

The invention relates to immunogenic peptides comprising T-cell epitopes and oxidoreductase motifs comprising a modified cysteine, and their use in regulating the immune response in subjects.

The present disclosure relates to extracellular vesicles (EVs) that are capable of targeting a cell in the CNS of a subject. Also provided herein are methods for producing the EVs and methods for using the EVs to treat and/or prevent diseases or disorders of the CNS (e.g., neurological disorders).
