Full Analysis
Moderna (MRNA) and Merck reported positive Phase 3 clinical trial data for their combination therapy of an individualized mRNA melanoma vaccine, intismeran, and KEYTRUDA at the ESMO 2026 conference. The results were accepted for publication in The New England Journal of Medicine, providing peer-reviewed validation for the program. The study demonstrated a significant reduction in disease recurrence and distant metastasis among patients with Stage IIB to IV resected melanoma receiving the combination regimen compared to KEYTRUDA alone.
