Five-Year Analysis of Adjuvant Pembrolizumab or Placebo in Stage III Melanoma.

Abstract

Pembrolizumab or Placebo in Stage III MelanomaPatients with stage III melanoma randomly received adjuvant pembrolizumab or placebo. Five-year recurrence-free survival was 55.4% (95% CI, 50.8 to 59.8) versus 38.3% (33.9 to 42.7) and 5-year metastasis-free survival was 60.6% (56.0 to 64.9) versus 44.5% (39.9 to 48.9) for adjuvant pembrolizumab and placebo, respectively. No new safety signals were associated with adjuvant pembrolizumab.
