Summary for Patent: 8,883,760
Title:Cancer therapy using beta glucan and antibodies
Abstract: The present invention relates to methods of using neutral soluble glucan and monoclonal antibodies for antitumor therapy. Neutral soluble Beta (1,3; 1,6) glucan (NSG) enhances the tumoricidal activity of the innate immune system by binding to the C3 complement protein receptor CR3. The glucan does not stimulate the induction of inflammatory cytokines. Also described are methods of using whole glucan particles (WGP) as an immunomodulator by inducing a shift from a Th2 response to the Th1 response, leading to an enhanced antitumor cytotoxic T-cell response.
Inventor(s): Ross; Gordon D. (Prospect, KY)
Assignee: University of Louisville Research Foundation, Inc. (Louisville, KY)
Application Number:10/526,185
Patent Claims:1. A method of suppressing or eliminating mammary carcinoma stably expressing trastuzumab-specific antigen, comprising administering a yeast neutral soluble glucan and trastuzumab to a subject having mammary carcinoma stably expressing trastuzumab-specific antigen, wherein the glucan does not induce systemic release of inflammatory cytokines, and the glucan and trastuzumab together synergistically suppress or eliminate mammary carcinoma stably expressing trastuzumab-specific antigen.

2. The method of claim 1, wherein the yeast neutral soluble glucan is in a single helix conformation, a triple helix conformation, or a combination thereof.

3. The method of claim 1, wherein the yeast neutral soluble beta glucan is administered parenterally.
