  • Patent number: 11826399
    Abstract: The present invention provides, among other things, compositions and methods relating to detection and/or treatment cancer (e.g., one or more tumors) that expresses Neuropilin 1 (NRP1). The present invention provides methods of treating cancer that include administering a chlorotoxin agent to a subject (e.g., to a subject suffering from or susceptible to the cancer which may, in some embodiments, be a cancer that expresses NRP1). In some embodiments, a chlorotoxin agent for use in accordance with the present invention can be or comprise a chlorotoxin polypeptide and a payload moiety (e.g., as a covalent conjugate).

  • Patent number: 10539565
    Abstract: Provided herein are methods for determining the risk that a subject diagnosed with colorectal cancer will develop a recurrence of colorectal cancer and methods of predicting clinical outcome for a subject diagnosed with colorectal cancer by a) determining the level of expression for each marker of a panel of markers in a panel of tumor compartments in a tumor tissue sample from the subject, wherein the panel of markers comprises at least two of TEM1, HIF2?, CAIX, PDGFR?, fibronectin, collagen I, collagen IV, and CD31 and wherein the panel of tumor compartments comprises at least three tumor compartments of pure stroma, tumor, stromal vessel, and tumor vessel; b) determining the TAPPS score for said subject; and c) comparing the TAPPS score of the subject to the TAPPS score of a population of subjects diagnosed with colorectal cancer. Also provided are related computer-implemented methods and systems, kits, and tumor microarrays.

  • Patent number: 10509037
    Abstract: This invention relates to novel monoclonal antibodies that specifically bind to the alpha-folate receptor. In some embodiments, the antibodies inhibit a biological activity of folate receptor-? (FR-?). The antibodies are useful in the treatment of certain cancers, particularly cancers that have increased cell surface expression of the alpha-folate receptor (“FR-?”), such as ovarian, breast, renal, colorectal, lung, endometrial, or brain cancer. The invention also relates to cells expressing the monoclonal antibodies, antibody derivatives, such as chimeric and humanized monoclonal antibodies, antibody fragments, and methods of detecting and treating cancer using the antibodies, derivatives, and fragments.

  • Patent number: 10253106
    Abstract: This invention relates to the use of monoclonal and polyclonal antibodies that specifically bind to and have the ability in the alternative to become internalized by cells expressing folate receptor alpha (FRA) and to induce an immune effector activity such as antibody-dependent cellular cytotoxicity. The antibodies are useful in specific delivery of pharmacologic agents to FRA-expressing cells as well as in eliciting an immune-effector activity particularly on tumor cells and precursors. The invention is also related to nucleotides encoding the antibodies of the invention, cells expressing the antibodies; methods of detecting cancer cells; and methods of treating cancer using the antibodies.

  • Patent number: 10053509
    Abstract: The invention provides methods for inhibiting the interaction of endosialin with endosialin ligands. The inhibition is effectuated on the genetic level, by inhibiting endosialin gene expression, and on the protein level, by blocking the interaction of cell-surface expressed endosialin with ligands such as fibronectin and collagen. The invention provides methods for identifying inhibitors of the interaction of endosialin with endosialin ligands. Also provided are methods for inhibiting angiogenesis and neovascularization in vivo and in vitro.

  • Publication number: 20150141429
    Abstract: The present invention relates to tetraaza phenalen-3-one compounds which inhibit poly (ADP-ribose) polymerase (PARP) and are useful in the chemosensitization of cancer therapeutics. The induction of peripheral neuropathy is a common side-effect of many of the conventional and newer chemotherapies. The present invention further provides means to reliably prevent or cure chemotherapy-induced neuropathy. The invention also relates to the use of the disclosed PARP inhibitor compounds in enhancing the efficacy of chemotherapeutic agents such as temozolomide. The invention also relates to the use of the disclosed PARP inhibitor compounds to radiosensitize tumor cells to ionizing radiation. The invention also relates to the use of the disclosed PARP inhibitor compounds for treatment of cancers with DNA repair defects.
