Study 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).
Primary Outcome
RFS as assessed by investigator was defined as the time between the date of randomization to the date of first local or regional recurrence of the index lesion, distant metastasis, or death due to any cause; whichever occurred first. Participants were analyzed in the treatment group to which they were randomized. RFS as assessed by investigator is presented.
