To determine the overall response rate (ORR) using Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 criteria to neoadjuvant cemiplimab (REGN2810) in patients with stage II-IV cutaneous squamous cell carcinoma (cSCC) of the head and neck who are planned for definitive local surgery with or without radiation. SECONDARY OBJECTIVES: I. To determine the pathologic response rate to neoadjuvant REGN2810 in patients with stage II-IV cSCC of the head and neck. II. To determine the safety and tolerability of neoadjuvant REGN2810 in patients with stage II-IV cSCC of the head and neck who are planned for definitive local surgery and radiation. III. To estimate the 2-year disease-specific (DSS), disease-free (DFS) and overall survival (OS) compared to historical controls. IV. To determine the time to recurrence and patterns of failure. V. To evaluate the effects of neoadjuvant REGN2810 on the expression of PD-1 and potential related immune regulating targets in cSCC of the head and neck. OUTLINE: Patients receive cemiplimab intravenously (IV) over 30 minutes every 3 weeks. Cycles repeat every 3 weeks for up to 6 weeks with or without radiation therapy at the discretion of the treating physician in the absence of disease progression or unacceptable toxicity.
