MRK/MRNA cancer vaccine shines in adjuvant melanoma (RFS HR=0.56):

…the Phase 2b KEYNOTE-942/mRNA-4157-P201 trial of mRNA-4157/V940, an investigational personalized mRNA cancer vaccine, in combination with KEYTRUDA…demonstrated a statistically significant and clinically meaningful improvement in the primary endpoint of recurrence-free survival (RFS) versus KEYTRUDA alone for the adjuvant treatment of patients with stage III/IV melanoma following complete resection.

Adjuvant treatment with mRNA-4157/V940 in combination with KEYTRUDA reduced the risk of recurrence or death by 44% (HR=0.56 [95% CI, 0.31-1.08]; one-sided p-value=0.0266) compared with KEYTRUDA alone.

Note: If this had been a phase-3 trial, it would’ve been considered a failure since the standard cutoff for a one-sided p-value is 0.025. For a phase-2b, however, these results are just fine.
