Valeant Pharmaceuticals International has named Joseph C. Papa as its future chairman and chief executive officer. He is expected to join the company by early May. Papa will succeed J. Michael Pearson. Valeant's board had been searching for the right candidate to take over the chief executive role since March, when Pearson had returned from a two-month medical leave. Pearson is expected to remain as chief executive and a director until Papa arrives at Valeant. Papa, 60, has more than 35 years of experience in the pharmaceutical, healthcare services and specialty pharmaceutical industries. He will join Valeant from Perrigo, a global healthcare supplier, where he has served as chief executive officer since 2006, and was appointed chairman in 2007. Prior to Perrigo, he served from December 2004 to October 2006 as chairman and chief executive officer of the pharmaceutical and technologies services segment of Cardinal Health. From 2001 to 2004 he was president and chief operating officer of Watson Pharmaceuticals. He has also held management positions at DuPont Pharmaceuticals, Pharmacia Corporation, G.D. Searle & Co. and Novartis. He currently serves as a director of Smith & Nephew, a developer of medical devices.
