Immunomedics Files Federal Lawsuit Against venBio

MORRIS PLAINS, N.J., Feb. 21, 2017 (GLOBE NEWSWIRE) -- Immunomedics, Inc. (NASDAQ: IMMU ) (“Immunomedics” or “the Company”) today announced that it has filed a federal lawsuit and a motion seeking injunctive relief against venBio Select Advisor LLC (“venBio”) and venBio’s four director candidates arising out of venBio’s continuing material violations of federal securities laws in connection with the Company’s upcoming 2016 Annual Meeting of Stockholders, which is scheduled for March 3, 2017. The Company filed the federal lawsuit on February 17, 2017, in the United States District Court for the District of Delaware and filed the motion for injunctive relief today.

The Company’s complaint asserts that venBio has violated — and continues to violate — the federal securities laws and proxy rules by, among other things, intentionally delaying the filing of its Schedule 13D in respect of its greater than 5% ownership of the Company by over five months in order to conceal its intent to try to take control of the Company’s Board of Directors; failing to disclose all of the members of its Schedule 13D and proxy soliciting group who, together with venBio, hold as much as 19% of the Company’s stock; making false and misleading statements about Immunomedics and its Board and management; failing to file solicitation materials in a timely manner with the SEC; and, unlawfully announcing purported preliminary proxy voting results. Immunomedics brought this suit to protect the stockholder franchise and to ensure that Immunomedics stockholders are in possession of timely, accurate and complete information in order to make fully informed decisions at the 2016 Annual Meeting. The suit seeks to enjoin venBio from further violations and also to mandate venBio to make full disclosures promptly to all stockholders in sufficient time prior to the 2016 Annual Meeting.

As previously announced, venBio filed a lawsuit in the Delaware Court of Chancery. The Chancery Court held a hearing on February 17, 2017. The Chancery Court refused venBio’s request to enjoin any aspect of the transaction with Seattle Genetics prior to the March 3, 2017, Annual Meeting.

About Immunomedics Immunomedics (the “Company”) 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 eight clinical-stage product candidates. Immunomedics’ portfolio of investigational products 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. IMMU-132 has received Breakthrough Therapy Designation from the FDA for the treatment of patients with triple-negative breast cancer who have failed at least two prior therapies for metastatic disease. 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 306 active patents in the United States and more than 400 foreign patents, protects its product candidates and technologies.
