Merck's Oral PCSK9 Inhibitor Enlicitide Decanoate Slashes LDL-C by 64.6%, Earns FDA Priority Voucher
summarizeSummary
Merck announced highly positive Phase 2 results for its investigational oral PCSK9 inhibitor, Enlicitide Decanoate, demonstrating a significant 64.6% reduction in LDL-C from baseline at eight weeks. This performance notably surpassed guideline-recommended oral non-statin therapies when added to background statins. Further bolstering its potential, the FDA selected Enlicitide for a Commissioner's National Priority Voucher in December 2025, signaling regulatory confidence and potential expedited review. This development is a material positive for Merck's pipeline, offering a promising new asset in the large cardiovascular market, which is crucial as the company faces future revenue declines from Keytruda's patent expiration. The safety profile was consistent with previous trials, showing no meaningful differences in adverse events. Investors will now watch for the drug's progression into Phase 3 trials and subsequent regulatory milestones.
