Immunomedics Announces Termination of Epratuzumab Licensing Agreement With UCB

MORRIS PLAINS, N.J., Feb. 26, 2016 -- Immunomedics, Inc., (Nasdaq:IMMU) today announced receipt of a notice from UCB terminating the May 2006 Development, Collaboration and License Agreement for epratuzumab for all non-cancer indications worldwide. Under the terms of the Agreement, the companies will now begin the transition process in a timely and orderly fashion.

“The return of the worldwide rights of epratuzumab for all non-cancer indications allows us to examine all options to maximize its value, not only in oncology but also in autoimmune diseases,” commented Cynthia L. Sullivan, President and Chief Executive Officer of Immunomedics. “Epratuzumab is being studied in a Phase 3 clinical trial in pediatric patients with acute lymphoblastic leukemia sponsored by a European consortium, and Bayer has begun studying epratuzumab as a thorium-227-labeled antibody in patients with advanced non-Hodgkin lymphoma,” Ms. Sullivan further remarked.

About Immunomedics
Immunomedics is a clinical-stage biopharmaceutical company developing monoclonal antibody-based products for the targeted treatment of cancer, autoimmune disorders and other serious diseases. Immunomedics’ advanced proprietary technologies allow the Company to create humanized antibodies that can be used either alone in unlabeled or “naked” form, or conjugated with radioactive isotopes, chemotherapeutics, cytokines or toxins. Using these technologies, Immunomedics has built a pipeline of nine clinical-stage product candidates. Immunomedics’ most advanced candidate is ⁹⁰Y-clivatuzumab tetraxetan. This radiolabeled antibody is in an international Phase 3 registration trial in patients with advanced pancreatic cancer. Immunomedics expects patient enrollment to be completed in calendar year 2016. Immunomedics’ portfolio of investigational products also includes antibody-drug conjugates (ADCs) that are designed to deliver a specific payload of a chemotherapeutic directly to the tumor while reducing overall toxic effects that are usually found with conventional administration of these chemotherapeutic agents. Immunomedics’ most advanced ADCs are sacituzumab govitecan (IMMU-132) and labetuzumab govitecan (IMMU-130), which are in Phase 2 trials for a number of solid tumors and metastatic colorectal cancer, respectively. Immunomedics has a research collaboration with Bayer to study epratuzumab as a thorium-227-labeled antibody. Immunomedics has other ongoing collaborations in oncology with independent cancer study groups. The IntreALL Inter-European study group is conducting a large, randomized Phase 3 trial combining epratuzumab with chemotherapy in children with relapsed acute lymphoblastic leukemia at clinical sites in Australia, Europe, and Israel. Immunomedics also has a number of other product candidates that target solid tumors and hematologic malignancies, as well as other diseases, in various stages of clinical and preclinical development. These include combination therapies involving its antibody-drug conjugates, bispecific antibodies targeting cancers and infectious diseases as T-cell redirecting immunotherapies, as well as bispecific antibodies for next-generation cancer and autoimmune disease therapies, created using its patented DOCK-AND-LOCK^® protein conjugation technology. The Company believes that its portfolio of intellectual property, which includes approximately 282 active patents in the United States and more than 400 foreign patents, protects its product candidates and technologies.
