Immunomedics Announces Five Presentations at 2015 ASCO Focusing on Antibody-Drug Conjugate Programs

MORRIS PLAINS, N.J., May 14, 2015 (GLOBE NEWSWIRE) -- Immunomedics, Inc., (Nasdaq:IMMU) today announced that two of its five abstracts submitted to the 2015 Annual Meeting of the American Society of Clinical Oncology (ASCO) have been accepted as oral presentations.

The two oral presentations will be on the Company's second generation antibody-drug conjugate (ADC) programs for solid cancer therapy. Leading that program is sacituzumab govitecan, an anti-TROP-2 antibody conjugated with SN-38, an active drug from irinotecan. Irinotecan is approved for the treatment of patients with colorectal cancer. Results from a Phase 2 study of sacituzumab govitecan in patients with advanced lung cancer will be updated in one of the 2 oral presentations. In addition to this oral presentation, results with sacituzumab govitecan in patients with late-stage triple-negative breast and gastrointestinal cancers will be reported in a Poster Discussion and a Poster Sessions, respectively.

Also presented, in the same Oral Abstract Session as sacituzumab govitecan, will be initial results from a Phase 2 study of labetuzumab govitecan, another SN-38-containing ADC, for patients with metastatic colorectal cancer. The fifth presentation will feature a pilot study on TF2, a bispecific antibody, for pretargeted imaging of breast cancer in a Poster Session.

The ASCO conference will be held at the McCormick Place Convention Center in Chicago, Illinois, from May 29 – June 2, 2015. Details of the five presentations are listed below (all times are in Central Time):

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 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 patient enrollment to be completed in calendar year 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 267 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.
