A group of eight Democratic senators is asking biopharma companies to spill the beans about their private most-favored-nation pricing deals with U.S. President Donald Trump. Led by Sen. Ron Wyden, D-Ore., ranking member of the Senate Finance Committee, the senators sent letters Dec. 11 to Astrazeneca plc, Eli Lilly and Co., Novo Nordisk A/S and Pfizer Inc. seeking the details of those deals. While it’s difficult to discern how the deals will benefit patients, it’s clear the companies stand to gain a lot from the agreements, the letter asserted.
