In two phase III studies, Merck & Co. Inc.’s oral, once monthly proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor produced statistically significant and clinically meaningful cuts in low-density lipoprotein cholesterol levels.

First quarter 2025 results presentations were the first chance analysts have had to quiz pharma companies in public about their exposure to the threat of U.S. import tariffs and what action they are taking to mitigate the risks. BioWorld reporters have listened in to the analyst meetings and filleted out responses to the tariff question by CEOs and senior executives, to get an overview of how the sector as a whole is responding.
