Monrovia, Calif. - February 9, 2010 - Xencor, Inc., a company using Fc engineering for the discovery and development of next-generation antibodies, announced today the appointment of Edgardo Baracchini, Ph.D., to chief business officer. He brings more than 15 years of transactional experience to Xencor, most recently as senior vice president of business development at Metabasis Therapeutics until its merger with Ligand Pharmaceuticals in 2009.

"Ed's extensive background navigating research and development partnerships will be invaluable to Xencor as we continue to expand the adoption of XmAb® technology and maximize our pipeline assets," said Bassil Dahiyat, Ph.D., chief executive officer of Xencor.

Over the course of his career, Dr. Baracchini has structured and negotiated more than 60 business transactions with multinational and Asian pharmaceutical firms, biotechnology companies and leading universities. Prior to Metabasis, he was vice president of business development at Elitra Pharmaceuticals, director of business development at Agouron Pharmaceuticals, which focused on protein-based drug design, and assistant director of business development at Isis Pharmaceuticals. He earned a Ph.D. in molecular and cell biology from the University of Texas at Dallas and conducted his postdoctoral research at UCSD and The Scripps Research Institute. Dr. Baracchini also earned an M.B.A. from the University of California, Irvine.

"As evidenced by the company's string of partnerships last year, including Merck and Pfizer, Xencor's antibody engineering technology provides a unique offering to partners, particularly at a time when there's increasing competition in biologics," added Dr. Baracchini. "I look forward to working with the Xencor team to further utilization of this broad-based technology."
