California Joins Other States in Suing Companies Over Insulin Prices

Many Americans with diabetes still struggle to pay for their insulin, even though Medicare placed a cap on co-payments this month.
With a population of 39 million, California has now become the largest state to sue the major companies on the insulin market, accusing them of illegally inflating the price of the treatment and spawning a financial and public health crisis.
Rob Bonta, the state’s attorney general, said in announcing the lawsuit late last week that the companies had engaged in “unlawful, unfair and deceptive practices” in violation of California’s laws on competition.
Characterizing the U.S. insulin market as “an oligopoly,” Mr. Bonta took aim in the state’s lawsuit at three pharmaceutical companies, Eli Lilly, Novo Nordisk and Sanofi, which control 90 percent of the global insulin supply, and the pharmacy benefit managers, CVS Health, Express Scripts and OptumRx, which manage 80 percent of the U.S. insulin market.
Nearly 38 million Americans have diabetes, roughly 11 percent of the U.S. population. And about eight million people — including all of those with Type 1 diabetes and many with Type 2 — need insulin treatments. Well-insured patients owe nothing or a co-pay of $20 to $35 a month for insulin, while those without insurance or high deductible plans can be charged hundreds of dollars a month.
President Joe Biden in August signed the Inflation Reduction Act, which now caps insulin’s monthly cost at $35 for the more than three million insulin users with Medicare Part D drug plans. Nearly half this population is expected to benefit from the cap, according to a study published Friday in JAMA Network Open. Researchers found that 45 percent of those with a Part D plan covering insulin paid at least $35 monthly for it between 2013 and 2019, up from 22 percent in 2006. The higher cost meant this group was 61 percent less likely to take their insulin doses as prescribed.
But people under 65 will not benefit from the new caps, although lawmakers and public health experts have expressed hope that the Medicare pricing rules will put pressure on the industry overall.
