On Wednesday, the company Merck & Co announced that Ken Frazier leaves the post of chairman. He will be replaced by Chief Executive Officer Rob Davis, who has taken on extra responsibilities on December 1.
Frazier joined the company nearly 30 years ago, and over the years, he was helping the company to stay among the leaders in the drug production field.
He was steering the company during the difficult lawsuit related to the painkiller Vioxx, which was withdrawn from the market. He also played a pivotal role in the acquisition of US drug product manufacturer Schering-Plough. In 2009 the company received the possibility to sell the drug Keytruda. Then, this drug became Merck's best-selling product.
