He was appointed to the position of chief medical officer at TRACON in September 2005. A former co-chair of the Southwest Oncology Group (Lung Cancer Committee), Dr. Leigh has been involved in both medical and radiation oncology, directing programs in diverse areas including multiple solid tumors and a variety of hematologic malignancies. He was previously the head of global hematology/oncology clinical development at Biogen Idec, where he was responsible for managing the portfolio of oncology products in development, including regulatory filings for Rituxan® (rituximab) and Zevalin® (ibritumomab tiuxetan).

Dr. Leigh received his M.D. from the University of California, San Francisco, and trained in Radiation Oncology at the University of Arizona. He completed his post-doctoral work in radiation biology at Stanford University.

She has broad-ranging experience in formulating regulatory strategies, developing registration plans, and submitting applications to worldwide health authorities, in the therapeutic areas of oncology, HIV and ophthalmology. Previously, Ms. Moore spent eight years in drug development at the NIH, where she was responsible for regulatory affairs and for coordinating strategic alliances between government scientists, clinical investigators, and pharmaceutical companies for cancer and AIDS research and development. Ms. Moore received her B.S. in Pharmacy from the University of Georgia and her Masters in Administrative Science from the Johns Hopkins University.

Kim Weinberger, M.B.A., joined TRACON as head of clinical operations in July 2005. Ms. Weinberger has over 15 years of pharmaceutical industry experience focused in clinical operations, preclinical development, and team and project management.

“TRACON’s therapeutic strategy focuses only on those targets implicated in the growth and metastasis of cancer,” said Jay Lobell, J.D., chief operating officer of Paramount Biosciences and Chairman of TRACON’s Board of Directors. “This approach may minimize impact on healthy cells and may offer improved safety, efficacy, and quality of life benefits compared with those of cytotoxic and first generation targeted therapies. TRACON’s strategy and pipeline have compelling clinical and commercial potential, and this management team has the knowledge and expertise to realize the full value of these assets.”

About TRACON Pharmaceuticals, Inc.
TRACON Pharmaceuticals is an emerging biotechnology company focused on identifying, developing, and commercializing targeted therapies for cancer. The company’s product candidates target novel disease mechanisms and pathways. TRACON’s pipeline includes an antibody against CD105 and a novel nanoliposomal formulation embedded with the C6 fragment of ceramide, a biologic lipid known to induce apoptosis (programmed cell death) and inhibit growth of cancer cells. CD105 is a novel target involved in the formation of new blood vessels (angiogenesis) needed to support tumor growth. Unlike other approved or investigational anti-angiogenesis agents that block the signals that stimulate blood vessel growth, this antibody has been shown to attack tumor vasculature directly. Clinical trials of this novel antibody are planned in 2006. Nanoliposomal C6 may be used directly to induce apoptosis in cancer cells, or as a drug delivery platform for a variety of anti-cancer drugs and other agents. It is expected this program will enter Phase I trials in the second half of 2006. TRACON intends to manage and expand its pipeline through a variety of licensing and partnership transactions with academic institutions and biopharmaceutical companies.
