  • Patent number: 7399469
    Abstract: Particular anti-LFL2 antibody compositions are provided herein. These antibodies may be used for diagnosis, prognosis, therapeutic monitoring and treatment of cancer, especially breast cancer, head/neck cancer, lung cancer, ovarian cancer, stomach cancer and pancreatic cancer. Furthermore, anti-LFL2 antibodies are provided herein which target the LFL2 stump remaining after proteolytic cleavage of the extracellular domain of LFL2. Additionally, anti-LFL2 antibodies are provided herein which target the stroma surrounding cancer tumors, wherein said stroma-targeting anti-LFL2 antibodies disrupt the integrity of the stroma surrounding the cancer tumor, and also make the stroma more permeable to chemotherapeutic agents and other molecular drug agents that target tumor cells.

  • Patent number: 7390635
    Abstract: The present invention provides recombinant peptides that specifically and selectively bind to the human milk fat globule (HMFG) antigen, BA46. In particular, the present invention provides recombinant variants of the Mc3 antibody, including humanized versions of Mc3. The variant Mc3 peptides are particularly useful for diagnostic, prognostic, and therapeutic applications in the field of breast cancer. The present invention also provides methods for the humanization of antibodies such as murine monoclonal antibodies. The novel humanization methods are applied to the production of humanized Mc3 antibodies and it is shown that these humanized antibodies retain the ability to engage in high affinity binding to their cognate antigen. Such humanization enables the use of these antibodies for immunodiagnostic and immunotherapeutic applications in humans.
