Abstract: The present invention is directed to a polymeric carrier cargo complex, comprising as a cargo at least one nucleic acid (molecule) and disulfide-crosslinked cationic components as a (preferably non-toxic and non-immunogenic) polymeric carrier. The inventive polymeric carrier cargo complex allows for both efficient transfection of nucleic acids into cells in vivo and in vitro and/or for induction of an (innate and/or adaptive) immune response, preferably dependent on the nucleic acid to be transported as a cargo. The present invention also provides, pharmaceutical compositions, particularly vaccines and adjuvants, comprising the inventive polymeric carrier cargo complex and optionally an antigen, as well as the use of such the inventive polymeric carrier cargo complex and optionally an antigen for transfecting a cell, a tissue or an organism, for (gene-)therapeutic purposes as disclosed herein, and/or as an immunostimulating agent or adjuvant, e.g.

Abstract: The present invention is directed to a pharmaceutical composition including (eg for use as an adjuvant) a polymeric carrier cargo complex, comprising as a carrier a polymeric carrier formed by disulfide-crosslinked cationic components and as a cargo at least one nucleic acid (molecule) and at least one antigen associated with a tumour or cancer disease selected from; an idiotype immunoglobulin (e.g. an idiotype antibody or an idiotype B cell receptor); or at least one idiotype T cell receptor, or in each case a fragment, variant and/or derivative thereof. The inventive pharmaceutical composition allows for efficient induction of an adaptive immune response directed against the idiotype immunoglobulin or T cell receptor, particularly of a Th1-shiftet immune response.

Abstract: The present invention relates to vaccines comprising at least one mRNA encoding at least one antigen for use in the treatment of a disease in newborns and/or infants, preferably exhibiting an age of not more than 2 years, preferably of not more than 1 year, more preferably of not more than 9 months or even 6 months, wherein the treatment comprises vaccination of the newborn or infant and eliciting an immune response in said newborn or infant. The present invention is furthermore directed to kits and kits of parts comprising such a vaccine and/or its components and to methods applying such a vaccine or kit.

Abstract: The present invention relates to vaccines comprising at least one mRNA encoding at least one antigen for use in the treatment of a disease in an elderly patient preferably exhibiting an age of at least 50 years, more preferably of at least 55 years, 60 years, 65 years, 70 years, or older, wherein the treatment comprises vaccination of the patient and eliciting an immune response in said patient. The present invention is furthermore directed to kits and kits of parts comprising such a vaccine and/or its components and to methods applying such a vaccine or kit.

Abstract: The present invention relates to a vaccine/inhibitor combination comprising as a vaccine at least one antigen and as an inhibitor at least one inhibitor of the major histocompatibility complex (MHC) class I restricted antigen presentation. The present invention furthermore relates to a method of vaccination of a mammal using the inventive vaccine/inhibitor combination. The present invention also provides kit of parts comprising the inventive vaccine/inhibitor combination, preferably in different parts of the kit, e.g. for prior, concurrent or subsequent administration of the different parts. Additionally the invention relates to a pharmaceutical composition comprising the inventive vaccine/inhibitor combination to further improve the immune response against tumour cells and infected cells having lost the capability of MHC class I restricted antigen presentation.

Abstract: The present invention is directed to an inventive composition or vaccine composition comprising a) an adjuvant component comprising or consisting of at least one immunostimulatory nucleic acid sequence, complexed with a complexing agent; b) an antigen, preferably a protein or peptide antigen and/or a nucleic acid sequence encoding said antigen; and c) a carrier molecule for combined packaging the adjuvant component and the antigen. The present invention is also directed to the first medical use of such an inventive composition or vaccine composition and to the second medical use of such an inventive composition or vaccine composition or components thereof for the treatment of diseases, such as infectious or cancer or tumour diseases as defined herein. The present invention furthermore discloses kits comprising such a composition or vaccine composition.

Abstract: The present invention is directed to a method for treating tumors and cancer cells by administering an immunocytokine following radiation treatment. This combination of treatments can stimulate an immune response at irradiated and non-irradiated sites, which is useful in eradicating cancer cells that have spread from the site of the primary tumor. In addition, immunocytokines can be administered at a dose that is less that the maximum tolerated dose, which reduces the side effects associated with immunocytokine therapy.
