Adjuvant Anti-PD-1 Misses on OS in High-Risk Melanoma

Presented at the virtual American Society of Clinical Oncology (ASCO) annual meeting, the findings from the S1404 clinical trial demonstrated that, although the PD-1 inhibitor pembrolizumab (Keytruda) came up short in both the intent-to-treat (ITT) population and PD-L1-positive subgroup, relapse-free survival (RFS) was significantly improved compared with those who received either ipilimumab (Yervoy) or high-dose interferon.
