Official title

Phase II Neoadjuvant Study of PD-1 Inhibitor Pembrolizumab in PD-1 Naive Cutaneous Squamous Cell Carcinoma (cSCC)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This phase II single-arm two-stage neoadjuvant study of pembrolizumab in patients with PD-1 naïve high-risk resectable cutaneous squamous cell carcinoma (cSCC) will be conducted over a 52-week period. The study will include patients who have not undergone surgery to remove disease, to formally evaluate whether both biologically and clinically high-risk disease may benefit from neoadjuvant anti-PD-1 therapy. Response to neoadjuvant anti-PD-1 therapy will be evaluated for association with improved landmark Relapse-free Survival (RFS).
