President Donald Trump on Friday announced a new agreement with a major pharmaceutical manufacturer that will tie the company’s U.S. drug prices to the lowest rates offered in other developed countries, expanding the administration’s “most-favored-nation” policy for prescription drug costs.

The deal, during an Oval Office event with AstraZeneca Chief Executive Officer Pascal Soriot, follows a similar arrangement the administration announced in September with Pfizer. It marks the second major pharmaceutical pricing agreement under the White House’s executive order seeking to reduce medication costs for Medicaid and direct-to-consumer purchases.

Under the terms described by the White House, AstraZeneca will provide “most-favored-nation,” or MFN, pricing to all state Medicaid programs, meaning that U.S. patients will pay no more than the lowest price available for the same drugs in other developed countries. The administration said the agreement could save American taxpayers hundreds of millions of dollars annually.
