The U.S. Department of Health and Human Services (HHS) put biopharma companies on notice May 20: It’s time to commit to reducing prescription drug prices to reflect most-favored-nation (MFN) pricing in accordance with President Donald Trump’s May 12 executive order. HHS said it expects manufacturers to commit to aligning their U.S. prices for all brand products across all markets that don’t currently have generic or biosimilar competition with the lowest price of a set of economic peer countries.
