Immunomedics Inc was incorporated in Delaware in 1982. It is a biopharmaceutical company, which develops monoclonal antibody-based products for the targeted treatment of cancer, autoimmune and other serious diseases. It has developed proprietary technologies that allow it 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 targeted agents. Using these technologies, it has built a pipeline of therapeutic product candidates that utilize several different mechanisms of action. Its product candidate, epratuzumab, is currently in two Phase III clinical trials in lupus. In oncology, the Company is planning to launch a Phase III pivotal trial for clivatuzumab labeled with a radioisotope in pancreatic cancer patients. Other solid tumor therapeutics in Phase II clinical development includes two antibody-drug conjugates sacituzumab govitecan (IMMU-132) and labetuzumab govitecan (IMMU-130). 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. It has licensed its product candidate, epratuzumab, to UCB S.A., or UCB, for the treatment of all autoimmune disease indications. It manages its operations as one line of business of researching, developing, manufacturing and marketing biopharmaceutical products, particularly antibody-based products for the targeted treatment of cancer, autoimmune and other serious diseases, and it currently reports as a single industry segment. Its geographic locations include United States and Europe. It competes with Biogen Idec, Roche, GlaxoSmithKline, Seattle Genetics, ImmunoGen Merck Serono, Genmab, Celgene, Amgen, Bristol-Myers Squibb, Bayer Healthcare Pharmaceuticals, Pfizer, AstraZeneca and Eli Lilly, are engaged in the development of therapeutic autoimmune and oncology products. Its patents include approximately 267 active patents in the U.S. and more than 400 other issued patents all over the world. Its research and development activities, including testing in laboratory animals and in humans, its manufacture of antibodies, as well as the handling, labeling and storage of the product candidates that the company is developing, are all subject to stringent regulation, by the FDA in the U.S. and by comparable authorities in other countries.
