  • 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.

  • Patent number: 10023632
    Abstract: Hybridoma lines that secrete human monoclonal antibodies with high binding specificity and biological activity, particularly neutralizing activity against granulocyte-macrophage colony stimulating factor, and methods of generating the hybridoma lines are provided. Target antigens and epitopes are also provided. The antibodies may be used in therapeutic methods, for example in the treatment of cancer, infectious disease, or autoimmune disease.
