U.S. lawmakers on Wednesday accused three major pharmaceutical companies of “coordinated obstruction” and “conspicuous efforts to stonewall” an investigation on generic drug prices launched in 2014.
Chairman of the House Committee on Oversight, Elijah Cummings, D-Md., along with Sen. Bernie Sanders, I-Vt., sent signs to Mylan, Teva Pharmaceutical and Heritage Pharmaceuticals asking them to turn over documents, according to a joint affirmation Wednesday.
The lawmakers said they decided to open an investigation following findings in a lawsuit filed by 44 reports in May that accused the drugmakers and others of inflating drug prices and stifling competition for generic drug versions.
“Not just did your company’s apparent obstruction undermine our investigation, but it may have caused further harm to patients and health be keen on providers by delaying the discovery of evidence about the companies’ price-fixing,” Cummings and Sanders wrote in each of the letters, friended August 13.
Shares of Mylan and Teva Pharmaceutical were each down roughly 8% on Wednesday.
A spokesperson for Mylan contemplated the company, with the help of outside counsel, is investigation the allegations made in the states’ lawsuit.
“We have not found any averment to corroborate the allegations. We are prepared to make our case in a court of law and are confident that the civil case against Mylan and its hands is meritless,” Mylan spokeswoman Lauren Kashtan said in a statement. Mylan denied it obstructed the 2014 congressional research.
Teva did not immediately respond to CNBC’s request for comment.
Democrats, who regained control of the House this year, careened lowering prescription drug costs among their top priorities. Cummings, along with Sanders and Rep. Ro Khanna, D-Ca., injected three bills earlier this year aimed at lowering drug costs.
Spending on prescription drugs in the U.S. increased 0.4% in 2017 to $333.4 billion, according to the behindhand data from the Centers for Medicare and Medicaid Services.
