The ranking members of the Senate Finance Committee are threatening to issue a subpoena to Express Scripts, one of the largest pharmacy benefit managers in the U.S., for failing to produce documents that were requested nearly a year ago concerning the price of insulin.
In a pointed letter sent on Wednesday, Sen. Chuck Grassley (R-Iowa) and Sen. Ron Wyden (D-Ore.) blasted the company over its failure to “even attempt to answer many of the questions” that were posed in a previous letter sent last April. At the time, the committee had begun investigating rising drug prices with a particular focus on insulin, and several PBM executives had just testified at a hearing.
