Immunomedics (IMMU) – Potential Lupus Drug Gains U.S. Patent

MORRIS PLAINS, N.J., Jan. 8, 2010 (GLOBE NEWSWIRE) — Immunomedics, Inc. (Nasdaq:IMMU), a biopharmaceutical company focused on developing monoclonal antibodies to treat cancer and other serious diseases, today announced that its patent for “Immunotherapy of autoimmune disorders using antibodies which target B-cells” has been issued as U.S. patent no. 7,641,901. The patent covers the use of monoclonal antibodies that bind to the CD22 antigen on B-lymphocytes for treating autoimmune disorders. The allowed claims cover the use of epratuzumab, the Company’s proprietary humanized anti-CD22 monoclonal antibody, and other anti-CD22 antibodies, alone and in combination with other therapeutics, such as antibodies, cytokines, or drugs, for the treatment of a wide range of autoimmune diseases that include systemic lupus erythematosus, rheumatoid arthritis, Sjogren’s syndrome, multiple sclerosis, myasthenia gravis, diabetes mellitus, and ulcerative colitis.

“This patent further strengthens our intellectual property protection of epratuzumab, for the treatment of autoimmune diseases,” commented Cynthia L. Sullivan, President and CEO. “Our partner, UCB, has recently reported encouraging top-line results from their Phase IIb study of epratuzumab in lupus and is planning to initiate a Phase III program for 2010,” added Ms. Sullivan.

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 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 141 patents issued in the United States and more than 300 other patents issued worldwide, protects our product candidates and technologies.
