  • Publication number: 20140134170
    Abstract: Provided are methods of suppressing growth of hormone refractory breast tumors by contacting tumor cells with an ErbB3 inhibitor, preferably an anti-ErbB3 antibody. Also provided are methods for treating hormone refractory breast cancer in a patient by administering to the patient an inhibitor of heregulin binding to ErbB3 or to ErbB2/ErbB3 heterodimer, which inhibitor is an anti-ErbB3 antibody or an anti-ErbB2 antibody. The treatment methods can further comprise selecting a patient having a hormone refractory breast cancer and then administering the inhibitor to the patient. The treatment methods may also comprise administering an estrogen receptor antagonist, or an aromatase inhibitor to the patent and may at further comprise administering to the patient at least one additional anti-cancer agent that is not an ErbB3 inhibitor, an estrogen receptor antagonist, or an aromatase inhibitor to the patient in combination with the ErbB3 inhibitor.

  • Publication number: 20140127238
    Abstract: The invention provides methods for treating patients which methods comprise methods for predicting responses of cells, such as tumor cells, to treatment with therapeutic agents. These methods involve measuring, in a sample of the cells, levels of one or more components of a cellular network and then computing a Network Activation State (NAS) or a Network Inhibition State (NIS) for the cells using a computational model of the cellular network. The response of the cells to treatment is then predicted based on the NAS or NIS value that has been computed. The invention also comprises predictive methods for cellular responsiveness in which computation of a NAS or NIS value for the cells (e.g., tumor cells) is combined with use of a statistical classification algorithm. Biomarkers for predicting responsiveness to treatment with a therapeutic agent that targets a component within the ErbB signaling pathway are also provided.

  • Patent number: 8691225
    Abstract: The present invention provides a novel class of antibodies and antigen binding fragments thereof that bind the extracellular domain of ErbB3 receptor and inhibit various ErbB3 functions. For example, the antibodies and antigen binding fragments described herein are capable of binding to the receptor designated ErbB3 and inhibiting EGF-like ligand mediated phosphorylation of the receptor. Such antibodies and antigen binding fragments thereof have the useful characteristic of inhibiting the proliferation of cancer cells expressing ErbB3.
