Merck and Moderna Report 42% Relative Risk Reduction in Melanoma Trial

Merck and Moderna reported Phase 3 trial results showing their personalized mRNA therapy, combined with Keytruda, reduced melanoma recurrence or death risk by 42% compared to Keytruda alone. The study involved 1,137 patients, with 2-year recurrence-free survival at 82.2% for the combination vs. 70.0% for Keytruda. The therapy is still investigational, and the companies are engaging with regulators.
