Abstract:
Compositions and methods for detection and diagnosis of pancreatic cancer are disclosed. An engineered anti-thymocyte differentiation antigen 1 (Thy1) single-chain antibody and bioconjugates thereof can be used for detecting and diagnosing pancreatic adenocarcinoma. The anti-Thyl single-chain antibody selectively binds to the Thy1 antigen, which is overexpressed on pancreatic tumor neovasculature and precancerous lesions, and is capable of detecting pancreatic cancer even at the earliest stages of the disease. Thy1- targeted diagnostic agents can be produced by conjugation of the anti-Thyl single-chain antibody to various diagnostic agents, such as contrast agents, photoactive agents, or detectable labels that are useful for detection and medical imaging of pancreatic tumors.

Abstract:
Provided are isolated nucleic acid molecules encoding chimeric antigen receptors (CARs) that bind to tumor antigens. Also provided are isolated polypeptides and CARs encoded by the isolated nucleic acid molecules, vectors that include the isolated nucleic acid molecules, cells that include the isolated nucleic acid molecules, methods of making the same, and methods for using the same to generate a persisting population of genetically engineered T cells in a subject, expanding a population of genetically engineered T cells in a subject, modulating the amount of cytokine secreted by a T cell, reducing the amount of activation- induced calcium influx into a T cell, providing an anti-tumor immunity to a subject, treating a mammal having a MUC1-associated disease or disorder, stimulating a T cell-mediated immune response to a target cell population or tissue in a subject, and imaging a MUC1-associated tumor.
Abstract:
Provided herein are methods of treating cancers expressing specific biomarkers with HER3 and/or EGFR inhibitors, and provided herein are also biomarkers and uses thereof in determining likelihood of effective cancer treatment with HER3 and/or EGFR inhibitors. In one aspect, the disclosure provides methods for treating a cancer, comprising administering to a patient diagnosed with said cancer a therapeutically effective amount of a HER3 inhibitor, an EGFR inhibitor, or a combination of a HER3 inhibitor and an EGFR inhibitor. Also disclosed herein are kits comprising components for performing the methods for determining whether a patient diagnosed with cancer is indicated as likely to be responsive to treatment with a HER3 inhibitor and/or an EGFR inhibitor.
Abstract:
The present invention concerns compositions and methods of use of antibodies or antibody fragments that bind to an epitope located within the second cysteine-rich domain (Cys2, amino acid residues 1575-1725) of MUC5AC. The antibodies bind with high specificity and selectivity to pancreatic cancer and are of use for therapy, detection and/or diagnosis of pancreatic cancer. In preferred embodiments, therapeutic antibody may be conjugated to at least one therapeutic agent, such as 90 Y. Both in vivo and in vitro detection of pancreatic cancer may be performed with the subject methods and compositions. Specific dosages of radiolabeled antibody and/or gemcitabine, of use in human pancreatic cancer patients, are disclosed herein.
Abstract:
The present application relates to novel, anti-Target Epidermal Growth Factor Receptor (EGFR, GeneID1956) binder-drug conjugates (ADCs) of N,N-dialkyl auristatins, to effective metabolites of said ADCs, to methods for producing said ADCs, to the use of said ADCs for treating and/or preventing diseases, and to the use of said ADCs for producing pharmaceuticals for treating and/or preventing diseases, in particular hyperproliferative and/or angiogenic diseases, such as cancers. Such treatments can be carried out as monotherapy or in combination with other pharmaceuticals or additional therapeutic measures.
Abstract:
Described herein are compositions and methods of use of anti-pancreatic cancer antibodies or fragments thereof, such as murine, chimeric, humanized or human PAM4 antibodies. The antibodies show novel and useful diagnostic characteristics, such as binding with high specificity to pancreatic and other cancers, but not to normal or benign pancreatic tissues and binding to a high percentage of early stage pancreatic cancers. Preferably, the antibodies bind to pancreatic cancer mucins such as MUC1 or MUC5ac and are of use for the detection and diagnosis of early stage pancreatic cancer. In more preferred embodiments, the anti-pancreatic cancer antibodies can be used for immunoassay of serum samples, wherein the immunoassay detects a marker for early stage pancreatic cancer in serum. Most preferably, the serum is extracted with an organic phase, such as butanol, before immunoassay. Alternatively, immunoassay with PAM4 and anti-CA19.9 antibodies may be utilized to improve sensitivity for pancreatic cancer.
Abstract:
The present invention provides for recombinant monoclonal antibodies that bind to human colorectal and pancreatic carcinoma-associated antigens, along with nucleic acid sequences encoding the antibody chains, and the amino acid sequences corresponding to the nucleic acids, and uses for these antibodies, nucleic acids and amino acids.
Abstract:
The present invention provides ligand drug conjugates for targeted delivery of drugs to cells expressing GPC3. The ligand drug conjugates have potent cytotoxic activity against antigen-specific targets.
Abstract:
The present invention concerns chimeric cancer therapeutic molecules comprising a targeting moiety and an anti-cell proliferation moiety. The anti-cell proliferation moiety may comprise a cytotoxic agent or an apoptosis-inducing factor, in specific embodiments. In particular embodiments, the anti-cell proliferation mechanism of the chimeric molecules comprises apoptotic pathways. In additional embodiments, the chimeric molecules of the present invention provide sensitivity to chemotherapy in a cell that is resistant to the chemotherapy.
