Valeant Pharmaceuticals International has received two subpoenas from federal prosecutors in the US seeking information relating to its drug pricing, distribution and patient support practices.
Issued by the US attorney’s offices in the Southern District of New York and Massachusetts, the subpoenas also seek information and documents from Valeant regarding information it provided to the Centers for Medicare and Medicaid Services.
The company has been under scrutiny for steeply raising its drug prices.
Senator Claire McCaskill (D-MO) sent a letter seeking information relating to the company’s products Nitropress and Isuprel.
In response to the senator’s letter, the company provided the history of the two drugs, the reimbursement process for hospital procedures involving them, analysis and reasons underlying the company’s pricing decisions, and its programmes designed to improve patient access.
Valeant acquired these two drugs used in cardiac care in February and immediately increased their prices by 525% and 212% respectively.
