Drugmaker Merck says it has received a subpoena from federal prosecutors investigating the company's marketing of three drugs acquired through its 2009 acquisition of Schering Plough.
Merck & Co. Inc. disclosed the request for information from the Department of Justice in a regulatory filing Monday morning. The government is investigating marketing and selling of the brain cancer drug Temodar and hepatitis C drugs PegIntron and Intron A. The probe involves company activities between 2004 and today. Merck, based in Whitehouse Station, New Jersey, said it is cooperating with the government.
Merck and Schering Plough completed their merger in November 2009.
