Summary
This is a randomized, double-blind, study that compares pembrolizumab (MK-3475) with
placebo given as adjuvant therapy in participants with high-risk locally advanced
cutaneous squamous cell carcinoma (LA cSCC) that have undergone surgery with curative
intent in combination with radiotherapy. The primary hypothesis is that pembrolizumab is
superior to placebo in increasing recurrence free survival (RFS).
