MORRIS PLAINS, N.J., Oct. 12, 2010 (GLOBE NEWSWIRE) -- Immunomedics, Inc. (Nasdaq:IMMU), a biopharmaceutical company primarily focused on the development of monoclonal, antibody-based products for the targeted treatment of cancer, autoimmune and other serious diseases, today announced that additional claims for the patent family "Method and kit for imaging and treating organs and tissue," were issued as U.S. Patent No. 7,811,570. The new patent covers the use of antibodies to deplete normal cells in the spleen, including B cells, by targeting specific cell markers for the treatment of immune diseases. Comparable patents have also issued in Europe and Canada.

"Many autoimmune diseases have been shown to involve the B-cell population of lymphocytes, particularly in organs such as the spleen. Our patent covers the depletion of B-cells in the spleen for the treatment of immune diseases," commented Cynthia L. Sullivan, President and CEO. "We are pleased with these additional patent claims, which we intend to license out to potential corporate partners on a non-exclusive basis," she added.

About Immunomedics

Immunomedics is a New Jersey-based biopharmaceutical company primarily focused on the development of monoclonal, antibody-based products for the targeted treatment of cancer, autoimmune and other serious diseases. We have developed a number of advanced proprietary technologies that allow us to create humanized antibodies that can be used either alone in unlabeled or "naked" form, or conjugated with radioactive isotopes, chemotherapeutics, cytokines or toxins, in each case to create highly targeted agents. Using these technologies, we have built a pipeline of therapeutic product candidates that utilize several different mechanisms of action. We also have a majority ownership in IBC Pharmaceuticals, Inc., which is developing a novel Dock-and-Lock (DNL) methodology with us for making fusion proteins and multifunctional antibodies, and a new method of delivering imaging and therapeutic agents selectively to disease, especially different solid cancers (colorectal, lung, pancreas, etc.), by proprietary, antibody-based, pretargeting methods. We believe that our portfolio of intellectual property, which includes approximately 154 patents issued in the United States and more than 375 other patents issued worldwide, protects our product candidates and technologies.
