About Micromet, Inc. (www.micromet-inc.com)

Micromet, Inc. is a biopharmaceutical company developing novel, proprietary antibodies for the treatment of cancer, inflammation and autoimmune diseases. Three of its antibodies are in clinical development. MT103 (MEDI-538), the first antibody in Micromet's product pipeline developed utilizing the BiTE(R) antibody technology platform, is being evaluated in a phase 2 clinical trial for the treatment of patients with acute lymphoblastic leukemia, and in a phase 1 clinical trial for the treatment of patients with non-Hodgkin's lymphoma. BiTE antibodies represent a new class of antibodies that activate a patient's own cytotoxic T cells to eliminate cancer cells. Micromet is developing MT103 in collaboration with MedImmune, a subsidiary of Astra Zeneca plc. The second clinical stage antibody is adecatumumab (MT201), a human monoclonal antibody targeting EpCAM expressing tumors. Adecatumumab is being developed by Micromet in collaboration with Merck Serono in a phase 1b clinical trial evaluating adecatumumab in combination with docetaxel for the treatment of patients with metastatic breast cancer. The third clinical stage antibody is MT293 (formerly D93), also known as TRC093, a first-in-class humanized monoclonal antibody that inhibits angiogenesis and tumor cell growth by binding cleaved collagen. MT293, which is currently being tested in a phase 1 clinical trial, is licensed to TRACON Pharmaceuticals, Inc. and is being developed for the treatment of patients with cancer and age-related macular degeneration. In addition, Micromet has established a collaboration with Nycomed for the development and commercialization of MT203, Micromet's human antibody neutralizing the activity of granulocyte/macrophage colony stimulating factor (GM-CSF), which has potential applications in the treatment of various inflammatory and autoimmune diseases, such as rheumatoid arthritis, psoriasis, or multiple sclerosis.
