This phase III trial compares the effect of adding cemiplimab to standard therapy (surgery with or without radiation) versus standard therapy alone in treating patients with stage III/IV squamous cell skin cancer that is able to be removed by surgery (resectable) and that may have come back after a period of improvement (recurrent). The usual treatment for patients with resectable squamous cell skin cancer is the removal of the cancerous tissue (surgery) with or without radiation, which uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Immunotherapy with monoclonal antibodies, such as cemiplimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cemiplimab has been approved for the treatment of skin cancer that has spread or that cannot be removed by surgery, but it has not been approved for the treatment of skin cancer than can be removed by surgery. Adding cemiplimab to the usual treatment of surgery with or without radiation may be more effective in treating patients with stage III/IV resectable squamous cell skin cancer than the usual treatment alone.
PRIMARY OBJECTIVE: I. To determine if neoadjuvant immunotherapy combined with response-adapted oncologic surgery improves site-reported event-free survival (EFS) compared to standard-of-care surgery in resectable stage III/IV cutaneous squamous cell carcinoma (CSCC). SECONDARY OBJECTIVES: I. To compare utilization of adjuvant radiation between arms. II. To compare disease-free survival (DFS) between arms. III. To compare overall survival (OS) between arms. IV. To compare adverse events (Common Terminology Criteria for Adverse Events \[CTCAE\] version \[v\]5.0) between arms. V. To assess pathologic complete response in arm 2. PATIENT-REPORTED OUTCOMES: I. Compare changes in patient reported quality of life as measured by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) at 1, 6, and 12 months after surgery between treatment arms. (Primary objective) II. To compare patient reported symptoms functioning, and quality of life, as measured by the Cutaneous Squamous Cell Carcinoma NeoAdjuvant, Adjuvant and Perioperative 32 question scale (CSCC NAAP-32), Patient Reported Outcomes Measurement Information System (PROMIS)-Short Form (SF)-Anxiety, PROMIS-SF-Fatigue, and EuroQol-5D (EQ-5D), between arms at 1, 6, and 12 months after surgery. III. Develop a scoring algorithm and validate the CSCC-NAAP-32 for use in this patient population. EXPLORATORY OBJECTIVES: I. To compare disease-specific survival (DSS) between arms. II. To correlate pathologic response with DFS in arm 2. III. To assess overall response rate (ORR) in arm 2. IV. To compare patterns of failure between arms. V. To compare pathologic measurements of lymph node yield between arms. VI. To compare primary tumor specimen dimensions and volume between arms. OUTLINE: Patients are randomized to 1 of 2 arms. ARM 1: Patients undergo surgery per standard of care within 6 weeks of randomization. Starting within 6-12 weeks of surgery, patients may undergo image-guided radiation therapy (IGRT) with intensity modulated radiation therapy (IMRT) for 5 fractions per week for 6 weeks as clinically indicated. Patients also undergo computed tomography (CT), magnetic resonance imaging (MRI), and/or positron emission tomography (PET)/CT prior to treatment, and CT and/or MRI during follow up. Patients may also undergo optional collection of tissue, whole blood, and plasma on study. ARM 2: Patients receive cemiplimab intravenously (IV) over 30 minutes on day 1 of each cycle. Cycles repeat every 21 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients then undergo response-adaptive surgery 21 days after last dose of cemiplimab. Starting within 12 weeks of surgery, patients may undergo IGRT with IMRT for 5 fractions per week for 6 weeks as clinically indicated. Starting within 6 weeks of completion of surgery or radiation therapy (if indicated), patients without pathologic complete response (pCR) receive cemiplimab IV over 30 minutes on day 1 of each cycle. Cycles repeat every 42 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo CT, MRI, and/or PET/CT prior to treatment, and CT and/or MRI on study and during follow up. Patients may also undergo optional collection of tissue, whole blood, and plasma on study. After completion of study treatment, patients are followed up at 1, 6, and 12 months post-surgery then every 3 months for 2 years, every 6 months in year 3, and then annually thereafter.

Event-free survival (EFS)
Defined as the time from randomization to any of the following events: progression of disease that precludes surgery, toxic effects related to treatment that preclude surgery, inability to resect all gross disease), disease recurrence (local, regional, or distant) after surgery (or after radiographic complete response), disease progression after radiographic partial response or stable disease without surgery (or biopsy, as applicable), or death due to any cause, whichever occurs first. EFS rates will be estimated using the Kaplan-Meier method, and the stratified log-rank test will be used to assess whether perioperative immunotherapy (neoadjuvant/adjuvant) with response-adapted oncologic surgery improves EFS as recorded by the site compared to standard-of-care surgery in resectable stage III/IV cutaneous squamous cell carcinoma (CSCC).
Time frame: Up to 6 years
Utilization of adjuvant radiation
Rates of utilization of adjuvant radiation for each arm will be computed using a binomial distribution assumption. A 95% confidence interval (CI) for the rate difference between arms will be calculated using the stratified Newcombe (Wilson) method (Yan 2010).
Time frame: Up to 6 years
Disease-free survival (DFS)
DFS will use the same analytic methods as EFS.
Time frame: From randomization to recurrent or death, assessed up to 6 years
Overall survival (OS)
OS will use the same analytic methods as EFS.
Time frame: From randomization to death, assessed up to 6 years
Incidence of adverse events
Adverse events (AEs) will be graded using Common Terminology Criteria for Adverse Events version (v) 5.0. Counts and frequencies of all AEs by grade will be provided by each treatment arm. For the experimental arm, AEs will be summarized for each treatment phase (neoadjuvant, adjuvant, and post-treatment \[after adjuvant\]). Counts and frequencies will be provided for the worst grade AE experienced by the patient by treatment arm. The proportion of patients with at least one grade 3 or higher AE, serious AEs, AEs leading to discontinuation or death will be reported for each treatment arm. These analyses will be descriptive.
Time frame: At 30 days and then up to 6 years
Pathologic complete response
Site-reported pathologic response will be assessed using the following categories: pathological complete, major, and partial response, no pathological response (i.e., no complete, major, or partial response), and no pathological evaluation. Pathological responses at 1 and 2 years will be summarized using frequencies and percentages and tested using a chi-square test at a two-sided 5% significance level.
Time frame: At 1 and 2 years
