After more than a decade at Merck, Wendy Yarno, is leaving. The announcement was made this morning in an e-mail to Merck employees, according to Pharmaceutical Executive.

Yarno joined Merck in 1983 as a sales rep, went on to launch Cozaar and Hyzaar, and then eventually was named to oversee marketing for Merck’s human healthcare business. Most recently, she received press for her pivotal role in launching Januvia. In between, she spent a couple of years at Johnson & Johnson’s Ortho-Biotech unit.

As the mag notes, Yarno has been out in front about the importance of Merck’s transformation and the need to create better alignment among the different division, but all this alignment suggests that Yarno’s retirement might have come a bit earlier than expected. A source inside the company tells the mag this is just the first of many other changes expected to be announced shortly.
