The Food and Drug Administration on Wednesday said it will take steps to speed up the process of developing generic versions of complex biological drugs, in a bid to increase cheaper competition for expensive medicines and lower drug costs for Americans.

It’s the Trump administration’s latest move to rein in high prescription drug costs in the U.S., where medication prices are two-to-three times higher than those in other developed nations.

The move to support the development and approval of so-called biosimilars could be a blow to pharmaceutical companies, whose most profitable products are often biological products that treat serious and chronic diseases. The exact impact will depend on the drugmaker and its products.

The FDA’s new reforms “will take the five-to-eight year timeframe to bring a biosimilar to market and cut it in half,” the agency’s Commissioner Marty Makary said during a press conference on Wednesday.

During the event, Health and Human Services Secretary Robert F. Kennedy Jr. said the FDA has an “outdated and burdensome approval process that has slowed down the entry of biosimilars.” He said “even when [the drugs] do get approved, current laws often prevent pharmacists or patients from substituting them for patients who would benefit from a more affordable option.”
