SOUTH SAN FRANCISCO, Calif., March 16, 2016 (GLOBE NEWSWIRE) -- Five Prime Therapeutics, Inc. (Nasdaq:FPRX), a clinical-stage biotechnology company focused on discovering and developing innovative immuno-oncology protein therapeutics, announced changes to its Board of Directors. Mr. Brian Atwood, who has served as a board member since 2002 when he lead the initial round of investment in Five Prime on behalf of Versant Ventures, and as Chairman of the Board since January 2012, has retired from the board. He will now focus on his existing responsibilities to Versant Ventures, and the start-up of a new company he recently co-founded where he is president and chief executive officer.

Lewis T. "Rusty" Williams, M.D., Ph.D., President and Chief Executive Officer of Five Prime, has been appointed Chairman of the Board of Five Prime. Dr. Williams founded Five Prime in December 2001, has served as a member of the board since January 2002, and was Executive Chairman from July 2003 to January 2012. Mark McDade, who has served as a Five Prime board member since July 2006, was appointed the lead independent director.

“We are extremely grateful to Brian for his dedication to Five Prime and his 14 years of service on our Board of Directors,” said Dr. Williams. “Brian helped shape the vision and strategy of the company from the very beginning. We have benefitted from his deep experience in starting and growing companies, and his insight and counsel have been incredibly valuable to our board and internal team. We wish him well in his new role.”

Mr. McDade commented, “The Board is very pleased to have Rusty serve in the role of Chairman as well as CEO. He founded Five Prime 14 years ago and spent the early years building the company’s proprietary platform and working with the team to move multiple drugs from discovery into clinical studies. Under his leadership, Five Prime has established numerous value-driving collaborations and completed successful initial and follow-on public offerings. Importantly, throughout his tenure, Rusty has drawn on his extensive prior experience in the industry to bring scientific rigor, objectivity and a broader view of the therapeutic landscape to his role on the board.”
