TRACON Pharmaceuticals, Inc. and Micromet, Inc. announced today that TRACON has started the treatment of the first cancer patient in a Phase 1 clinical trial with TRC093

SAN DIEGO, CA, USA and BETHESEDA, MD, USA | July 11, 2007 | TRACON Pharmaceuticals, Inc. (TRACON), a biopharmaceutical company focused on the development of products for oncology and ophthalmology treatment, and Micromet, Inc., (NASDAQ: MITI), a biopharmaceutical company focused on the development of novel, proprietary antibody-based products for cancer, inflammatory and autoimmune diseases, announced today that TRACON has started the treatment of the first cancer patient in a Phase 1 clinical trial with TRC093.

TRC093 is a first-in-class humanized monoclonal antibody that inhibits angiogenesis and tumor cell growth by binding cleaved collagen, a component of the extracellular matrix of tumors that serves as the scaffold for new blood vessel and tumor growth. TRC093 has shown activity, as monotherapy or when combined with chemotherapy, in pre-clinical studies of melanoma, breast and pancreatic cancer.

TRC093 is currently being developed by TRACON in oncology and Age-Related Macular Degeneration (AMD), following execution of a license agreement with Micromet, Inc. in March 2007, granting TRACON worldwide rights to develop and commercialize D93 (now TRC093). TRC093 (D93) was generated and developed by Micromet up to the filing and acceptance of the IND.

“TRACON’s management team is cohesive and focused on execution. These qualities, combined with our excellent working relationship with Micromet and top-notch Phase 1 sites, have allowed us to initiate dosing within four months of execution of the license agreement,” said Charles Theuer, M.D., Ph.D., President and Chief Executive Officer of TRACON Pharmaceuticals, Inc. “Moving a humanized antibody into the clinic, that has the potential to treat multiple solid tumors in combination with chemotherapy and targeted agents, is a major milestone for TRACON in what will be a busy year for the company. We anticipate dosing two additional first-in-class cancer treatments later this year.”

The Phase 1 trial is designed to assess the safety, tolerability and pharmacokinetics, as well as preliminary anti-tumor activity, of TRC093 in patients with advanced cancer.

“We are very pleased to see that TRACON has initiated a broad development program very shortly after receiving the license from us in March of this year. The initiation of the Phase 1 study is an important milestone for the product and we are looking forward to the expansion of the program into age-related macular degeneration,” said Jens Hennecke, Vice President Business Development of Micromet.

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. Three product candidates are currently in clinical trials. MT103/MEDI-538, which is the first product candidate based on Micromet’s novel BiTE(R) product development platform, is being evaluated in a phase 1 clinical trial for the treatment of patients with non-Hodgkin’s lymphoma. The BiTE product development platform is based on a unique, antibody-based format that leverages the cytotoxic potential of T cells, widely recognized as 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, which has shown activity in patients with high EpCAM expression, 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, Inc. for MT103/MEDI-538 and Merck Serono for adecatumumab (MT201). Our third clinical stage product candidate is D93, also known as TRC093, a first-in-class humanized monoclonal antibody that inhibits angiogenesis and tumor cell growth by binding cleaved collagen, is being developed by TRACON Pharmaceuticals, Inc. in oncology and Age-Related Macular Degeneration (AMD) pursuant to a license agreement under which we have granted TRACON worldwide rights to develop and commercialize D93/TRC093. In addition, Micromet has established a collaboration with Nycomed for the development and commercialization of MT203, Micromet’s human antibody neutralizing the activity of GM-CSF, which may be important in the treatment of inflammatory diseases, such as rheumatoid arthritis.
