Methods and compositions for treating cancer are provided. Compositions comprising ceramide nanoliposomes are administered to a subject in need of such treatment. The composition administration also enhances immunotherapy. Further administering compositions in combination with tumor antigen specific T-cells, and/or compositions in combination with tumor antigen expressing cells, and/or said compositions in combination with antagonists of PD-1 provides for enhanced results. Administration of the compositions provides for effective treatment of tumors including regression and eradication of established tumors.

The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.

Provided are methods of treating a FGF19-mediated cancer or tumor in a subject by administering to the subject an anti-IL-6 antibody or an anti-IL-6 receptor antibody or an inhibitor of STAT3/JAK signaling pathway, and pharmaceutical compositions relating thereto.

The present disclosure pertains to the technical field of immunotherapy or disease prevention and treatment with vaccines, in particular to a heterocyclic compound containing two or more sulfur atoms and an application thereof in preparing a nano-vaccine. Provided is the application of the heterocyclic compound containing at least two sulfur atoms and capable of being covalently or non-covalently linked to a polypeptide in preparing the nano-vaccine. A nanoparticle prepared by self-assembly of the compound and an antigen can enter the dendritic cytoplasm in nonendocytic pathway, thereby improving the uptake efficiency of the antigen and an immune adjuvant. In the process of entering a cell, the nano-vaccine can effectively avoid or reduce biodegradation of the antigen or nucleic acid adjuvant caused by enzymes in lysosomes, and therefore the nano-vaccine can efficiently activate the dendritic cells and improve the cross-presentation of the antigen, thereby effectively activating CD8+ T cells and promoting T cell proliferation. Therefore, the nano-vaccine can prevent tumor cell proliferation and virus infection by efficient immune activation and immune regulation.

Provided herein are CAR-T compositions that are directed to GPC3, including a chimeric receptor, and engineered immune cells to GPC3. The disclosure also provides vectors, compositions, and methods of treatment using GPC3 antigen binding molecules and engineered immune cells, optionally in combination with expression of IL-18. GPC3 CAR compositions provided herein can be used for the treatment of certain cancers.

Isolated GPC3-derived epitope peptides having Th1 cell inducibility are disclosed herein. Such peptides can be recognized by MHC class II molecules and induce Th1 cells. In preferred embodiments, such a peptide of the present invention can promiscuously bind to MHC class II molecules and induce GPC3-specific cytotoxic T lymphocytes (CTLs) in addition to Th1 cells. Such peptides are thus suitable for use in enhancing immune response in a subject, and accordingly find use in cancer immunotherapy, in particular, as cancer vaccines. Also disclosed herein are polynucleotides that encode any of the aforementioned peptides, APCs and Th1 cells induced by such peptides and methods of induction associated therewith. Pharmaceutical compositions that comprise any of the aforementioned components as active ingredients find use in the treatment and/or prevention of cancers or tumors including, for example, hepatocellular carcinoma and melanoma.

A tumor vaccine, a preparation method therefor, and use of the tumor vaccine thereof. A pharmaceutical combination with a first membrane component having a membrane derived from the inner membrane of bacteria, the pharmaceutical combination further includes components derived from other organisms than the bacteria. A method for enhancing an uptake of a target antigen by an immune cell, activating an immune cell, enhancing an innate immunity and/or a specific immune response and/or preventing and/or treating a tumor. A tumor vaccine for preventing postoperative recurrence of cancer.

The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.

The invention features compositions and methods for treating and preventing cancer. In one aspect, isolated fusion proteins are provided that comprise a DNAJBI portion and a PRKACA portion. In a further aspect, compositions are provided, including immunogenic compositions that comprise an isolated fusion protein comprising a DNAJBI portion and a PRKACA portion. In a yet further aspect, a cancer vaccine is provided that comprises an isolated fusion protein comprising a DNAJBI portion and a PRKACA portion.

Disclosed are compositions and methods for an immunotherapy in a subject containing a vaccine construct for an immunization against a purified tumor antigen and a checkpoint inhibitor for treating a tumor in the subject, in which the tumor is characterized as comprising a low frequency of neoantigen expression and the composition potentiates an anti-tumor immune response without inducing autoimmunity in the subject. A pharmaceutical composition containing the composition as an active component and a pharmaceutically acceptable carrier, and a combinatorial composition containing a vaccine construct for an immunization against a purified tumor antigen and an immune checkpoint inhibitor, in which the tumor is characterized as comprising a low frequency of neoantigen expression, are also described.
