The present invention relates to therapeutic ADCs comprising a drug attached to an anti-cancer antibody or antigen-binding antibody fragment. Preferably the drug is SN-38. More preferably the antibody or fragment thereof binds to Trop-2 and the therapy is used to treat a Trop-2 positive cancer. Most preferably the antibody is hRS7. The ADC is administered to a subject with a cancer in combination with an ABCG2 inhibitor. The combination therapy is effective to treat cancers that are resistant to drug alone and/or to ADC alone.

The present invention relates to methods of diagnosing and methods of treating hepatocellular carcinoma in a subject. The invention also relates to antagonists of PLVAP proteins, such as antibodies that specifically bind PLVAP proteins, as well as compositions and kits comprising antagonists of PLVAP proteins. The invention further relates to humanized antibodies that specifically bind PLVAP protein.

Methods for developing disease-related nanobodies and related products and kits are provided. The disease-specific proteins are extracellular matrix (ECM) proteins, domains or epitopes that are associated with various aspects of disease and are not present, or are present in very low quantities, in non-diseased individuals. Highly effective nanobodies capable of specifically binding to these ECM protein epitopes useful in in vivo imaging assays, the detection, diagnosis and treatment of diseases as well as monitoring therapeutic progress in a patient with a disease are provided herein.

The present invention aims to provide a radionuclide-labeled anti-MUC5AC humanized antibody that is superior in the specificity for mucin subtype 5AC (MUC5AC) and accumulation in tumor. The present invention provides a conjugate of a radionuclide and an antibody, wherein the radionuclide is a nuclide that emits ?-rays, and the antibody is a humanized antibody that specifically binds to mucin subtype 5AC and has a heavy chain variable region consisting of the amino acid sequence shown in any of SEQ ID NOs: 1 to 4, and a light chain variable region consisting of the amino acid sequence shown in any of SEQ ID NOs: 5 to 8.

The present invention relates to therapeutic antibodies for the treatment of cancer, and more specifically, for the treatment of prostate, bladder, and/or pancreatic cancer. An embodiment of the present invention is an anti-glypican-1 (GPC 1) antibody, which may be conjugated to at least one cytotoxic agent that is toxic to a prostate, bladder, and/or pancreatic cancer cell.

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. In particular, the present invention relates to several novel peptide sequences and their variants derived from HLA class I and class II molecules of human tumor cells that can be used in vaccine compositions for eliciting anti-tumor immune responses or as targets for the development of pharmaceutically/immunologically active compounds and cells.

A peptide consists of the amino acid sequence IYVTSIEQI (SEQ ID NO: 214) in the form of a pharmaceutically acceptable salt, in which the peptide has the ability to bind to an MHC class-I molecule and, when bound to MHC, is capable of being recognized by CD8+ T cells. A composition contains a peptide consisting of the amino acid sequence IYVTSIEQI (SEQ ID NO: 214), an adjuvant, and a pharmaceutically acceptable carrier.

The invention provides anti-GPC3 antibodies and immunoconjugates and methods of using the same.

A peptide consists of the amino acid sequence ALVEQGFTV (SEQ ID NO: 5) in the form of a pharmaceutically acceptable salt, in which the peptide has the ability to bind to an MHC class-I molecule and, when bound to MHC, is capable of being recognized by CD8+ T cells. A composition contains a peptide consisting of the amino acid sequence ALVEQGFTV (SEQ ID NO: 5), an adjuvant, and a pharmaceutically acceptable carrier.

A peptide consists of the amino acid sequence GVLPGLVGV (SEQ ID NO: 56) in the form of a pharmaceutically acceptable salt, in which the peptide has the ability to bind to an MHC class-I molecule and, when bound to MHC, is capable of being recognized by CD8 T cells. A composition contains a peptide consisting of the amino acid sequence GVLPGLVGV (SEQ ID NO: 56), an adjuvant, and a pharmaceutically acceptable carrier.
