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.Our lead product candidate,
epratuzumab, is currently in two Phase III clinical trials in lupus. In
oncology, we are planning to launch a Phase III pivotal trial for clivatuzumab
labeled with a radioisotope in advanced pancreatic cancer patients. Other
solid tumor therapeutics in Phase II clinical development include 2
antibody-drug conjugates, labetuzumab-SN-38 (IMMU-130) and hRS7-SN-38
(IMMU-132).We also have a majority ownership in IBC Pharmaceuticals, Inc.,
which is developing a novel DOCK-AND-LOCK™ (DNL™) method with us for making
fusion proteins and multifunctional antibodies. DNL™ is being used
particularly to make bispecific antibodies targeting cancers and infectious
diseases as a T-cell redirecting immunotherapy, as well as bispecific
antibodies for next-generation cancer and autoimmune disease therapies. We
believe that our portfolio of intellectual property, which includes
approximately 230 active patents in the United States and more than 400
foreign patents, protects our product candidates and technologies.Our
strength in intellectual property has resulted in the top-10 ranking in the
2012 IEEE Spectrum Patent Power Scorecards in the Biotechnology and
Pharmaceuticals category.For additional information on us, please visit our
