MORRIS PLAINS, N.J., April 6, 2015 (GLOBE NEWSWIRE) -- Immunomedics, Inc., (Nasdaq:IMMU) today announced that at the upcoming 2015 Annual Meeting of the American Association for Cancer Research (AACR), the Company will provide an update on the multicenter Phase 1/2 study of its lead investigational antibody-drug conjugate (ADC), sacituzumab govitecan, in patients with various solid cancers.
The Company has previously reported meaningful objective response rates, which were determined by computed tomography, in three major indications. Patient populations included triple-negative breast cancer, small cell lung cancer and non-small cell lung cancer. The oral presentation at AACR will include updated results in these three indications, and also the first therapy results in patients with advanced, heavily-pretreated colorectal and esophageal cancers.
Dr. Alexander N. Starodub of Indiana University Health Center for Cancer Care, Goshen, Indiana, one of the Principal Investigators of the multicenter study, will present the updated results. The oral presentation, entitled: "Advanced Solid Cancer Therapy with a Novel Antibody-Drug Conjugate (ADC), Sacituzumab Govitecan (IMMU-132): Key Preclinical and Clinical Results," is scheduled for Monday, April 20, 2015 at 3:10 PM – 3:30 PM in Room 103 of the Pennsylvania Convention Center.
About Sacituzumab Govitecan
Sacituzumab govitecan is a next generation ADC designed for targeted therapy of solid cancers. The agent was created by site-specifically conjugating a TROP-2-targeting antibody with a high ratio of a moderately toxic drug, SN-38, using a pH sensitive linker. TROP-2 is a receptor found on many human cancer cells, such as cancers of the breast, cervix, colon and rectum, kidney, liver, lung, ovary, pancreas, and prostate, but with only limited expression in normal human tissues. In an animal model of human pancreatic cancer, the ADC delivered up to 135-times the amount of SN-38 to the tumor than when irinotecan, the parent drug of SN-38, was given.
Sacituzumab govitecan has received Fast Track designation from the U.S. Food and Drug Administration (FDA) for the treatment of patients with triple-negative breast cancer who have failed prior therapies for metastatic disease and patients with small-cell lung cancer. The ADC has also been designated an orphan drug by FDA for the treatment of patients with small-cell lung or pancreatic cancers.
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 has an ongoing collaboration with UCB, S.A. (UCB), to whom the Company licensed epratuzumab for the treatment of all non-cancer indications worldwide. UCB expects Phase 3 data in systemic lupus erythematosus in the first half of 2015. Immunomedics is exploring epratuzumab in oncology in collaboration with independent cancer study groups. Immunomedics' most advanced candidate to which it retains worldwide rights for all indications is 90Y-clivatuzumab tetraxetan. The Company initiated a Phase 3 registration trial in January 2014 in patients with advanced pancreatic cancer and expects topline data in mid-2016. Immunomedics' portfolio of wholly owned product candidates 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 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 pre-clinical development. These include 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 265 active patents in the United States and more than 400 foreign patents, protects its product candidates and technologies. Immunomedics' strength in intellectual property has resulted in a top-8 ranking in the Biotechnology industry by the Patent Board for the 2014 fiscal year.
