  • Patent number: 10975163
    Abstract: The present invention provides compositions and methods for increasing the permeability of a stroma around a neoplasm, and particularly to cancer cells associated with solid tumors. In one embodiment, combining a therapeutic IgE antibody with an anti-cancer agent in accordance with the invention increases the delivery of the anticancer agent to the site of, for example, a solid tumor in a subject. In one embodiment, combining a therapeutic IgE antibody with an anti-cancer agent in accordance with the invention potentiates a tumor's responsiveness and sensitivity to the anti-cancer agent.

  • Patent number: 8038994
    Abstract: Disclosed are methods for treating cancer comprising administering a xenotypic antibody and a chemotherapeutic drug to a patient suffering from cancer. Also disclosed is a method for inducing a host immune response in a patient against a multi-epitopic in vivo tumor antigen present in the host serum, which antigen does not elicit an effective host immune response, comprising administering to the patient a chemotherapeutic drug and a composition comprising a binding agent that specifically binds to a first epitope on the antigen and allowing the binding agent to form a binding agent/antigen pair, wherein an effective host immune response is elicited against a second epitope on the antigen.
