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.
