- Teva Pharmaceutical shares sink after the company is accused of orchestrating a sweeping scheme to inflate drug prices.
- Forty-four U.S. states, led Connecticut Attorney General William Tong, claim 20 drug companies "systematically" divided up the market for generic drugs to avoid competing with one another.
Shares of drugmakers Mylan, which was also named in the lawsuit, were trading 10% lower in afternoon trading.
The states, led Connecticut Attorney General William Tong, claim 20 drug companies, including Teva USA, "systematically" divided up the market for generic drugs to avoid competing with one another, according to a 500-page lawsuit filed late Friday in the U.S. District Court in Connecticut. In some cases, pharmaceutical executives conspired to either prevent prices from dropping or raise them, the lawsuit claimed.
"This is an organized effort to conspire and fix prices — a highly illegal violation of antitrust laws," Tong said.
The lawsuit comes as President Donald Trump and Congress attempt to bring down high prescription drug prices, which accounted for roughly 12% of total health-care spending in the U.S. in 2016. Just last week, the Trump administration announced it would required pharmaceutical companies to disclose the list price of their prescription medicines in television commercials in an effort to "shame" them into lowering consumer costs.
In response to the lawsuit, a spokesperson for Teva said "the allegations in this new complaint, and in the litigation more generally, are just that – allegations."
"Teva continues to review the issue internally and has not engaged in any conduct that would lead to civil or criminal liability," the spokesperson said. "Teva delivers high-quality medicines to patients around the world, and is committed to complying with all applicable laws and regulations in doing so."
The generic drug industry was created by Congress in 1984 in an effort to bring down drug prices by allowing companies to make their own identical version of a drug once a brand-name drug's patent expired.
Israel-based Teva is the world's largest generic drugmaker.
