Micromet and TRACON Pharmaceuticals Sign Exclusive Worldwide License Agreement to Develop and Commercialize D93, a Humanized Antibody for Cancer Treatment

Start of Phase 1 Clinical Trial Planned for the Second Half of This Year

CARLSBAD, Calif., and SAN DIEGO, March 16 (HSMN NewsFeed) -- Micromet, Inc. (Nasdaq: MITI ), a biopharmaceutical company focused on the development of novel and proprietary antibody-based products for cancer, inflammatory and autoimmune diseases, and TRACON Pharmaceuticals, Inc., a privately held biopharmaceutical company focused on the development of products for cancer treatment, including agents that inhibit angiogenesis, today announced an agreement granting TRACON exclusive worldwide rights to develop and commercialize Micromet's D93 antibody with a novel mode of action for the treatment of cancer. TRACON Pharmaceuticals was founded in 2005 by Paramount BioSciences, LLC.

"TRACON's management team, with its specific expertise in the development of antibodies and small molecules that target angiogenesis, is an excellent partner for the development of D93 and we are looking forward to the start of clinical trials planned for the second half of this year," said Christian Itin, PhD, President and Chief Executive Officer of Micromet, Inc.

D93 is a recombinant humanized IgG1 monoclonal antibody that inhibits angiogenesis, tumor cell growth and metastasis by targeting cleaved collagen, which is predominantly produced in the extracellular matrix of tumors. Preclinical studies indicate that D93 has the potential to treat different types of cancer as a single agent and in combination with chemotherapeutics. Because of its anti-angiogenic activity, D93 may also provide a new therapeutic approach for other diseases involving neo-vascularization such as wet age-related macular degeneration or proliferative diabetic retinopathy. In 2006, Micromet filed an investigational new drug (IND) application with the U.S. Food and Drug Administration for clinical testing of D93 in patients with cancer.

"D93 is a first-in-class humanized antibody that will be developed for the treatment of a variety of cancers to complement other currently available therapies," said Charles P. Theuer MD, PhD, President and Chief Executive Officer of TRACON Pharmaceuticals.

Under the terms of the agreement, TRACON will be responsible for all development and commercial activities. TRACON plans to initiate a phase 1 clinical trial in the second half of this year. Under the terms of the agreement, TRACON will pay Micromet upfront and milestone payments of more than $100 million, if D93 is successfully developed and commercialized. In addition, Micromet will receive royalties on worldwide sales of D93.

About Micromet, Inc.

Micromet, Inc. ( is a biopharmaceutical company focusing on the development of novel, proprietary antibody-based products for cancer, inflammatory and autoimmune diseases. Two product candidates are currently in clinical trials. MT103 (MEDI-538), which is the first product candidate based on Micromet's novel BiTEĀ® product development platform, is being evaluated in a phase 1 clinical trial for the treatment of patients with non-Hodgkins lymphoma. The BiTEĀ® product development platform is based on a unique, antibody-based format that leverages the cytotoxic potential of T cells, the most powerful 'killer cells' of the human immune system. Adecatumumab (MT201), a recombinant human monoclonal antibody which targets EpCAM expressing tumors, has completed two phase 2a clinical trials, one in patients with breast cancer and the other in patients with prostate cancer. In addition, a phase 1b trial evaluating the safety and tolerability of MT201 in combination with docetaxel is currently ongoing in patients with metastatic breast cancer. Micromet has established collaborations with MedImmune and Merck Serono.
