Immunomedics is a clinical-stage biopharmaceutical company developing monoclonal antibody-based products for the targeted treatment of cancer, autoimmune disorders and other serious diseases. Our advanced proprietary technologies 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. Using these technologies, we have built a pipeline of eight clinical-stage product candidates.
Our 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. Our 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 FDA for the treatment of patients with triple-negative breast cancer who have failed at least 2 prior therapies for metastatic disease.
We have a research collaboration with Bayer to study epratuzumab as a thorium-227-labeled antibody. We have 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.
We also have 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 as T-cell redirecting immunotherapies, as well as bispecific antibodies for next generation cancer and autoimmune disease therapies, created using our patented DOCK-AND-LOCK® (DNL®) protein conjugation technology.
In addition to our potential therapeutic products, our proprietary technologies have also enabled us to develop highly specific diagnostic imaging agents, one of which, LeukoScan®, has been approved in Europe, Canada and Australia, where it is currently being marketed for the detection of bone infections.
We have two foreign subsidiaries, Immunomedics B.V. in the Netherlands and Immunomedics GmbH in Rödermark, Germany, to assist us in managing sales efforts and coordinating clinical trials in Europe. In addition, we have a majority-owned U.S. subsidiary, IBC Pharmaceuticals, Inc., which has been working since 1999 on the development of novel cancer radiotherapeutics using patented pretargeting technologies with proprietary, bispecific antibodies.
