Brief Summary:
This phase I trial studies how well cemiplimab before and after surgery works in treating patients with high risk cutaneous squamous cell cancer. 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. Giving cemiplimab before surgery may improve risk of the cancer returning in patients with high risk cutaneous squamous cell cancer.

Detailed Description:

PRIMARY OBJECTIVE:

I. To establish the pathologic response rate of neoadjuvant cemiplimab in cutaneous squamous cell carcinoma (cSCC).

SECONDARY OBJECTIVES:

I. To document the local recurrence rate of high-risk cSCC treated with adjuvant cemiplimab.

II. To document the systemic recurrence rate of high-risk cSCC treated with adjuvant cemiplimab.

III. To document the 6-month, 12-month, 2-year overall survival (OS), recurrence-free survival (RFS) for patients with high risk cSCC.

TERTIARY/EXPLORATORY OBJECTIVE:

I. To evaluate the immune profile of fresh tumor tissue, blood in patients with cSCC treated with cemiplimab.

OUTLINE:

NEOADJUVANT PHASE: Prior to standard of care surgery, patients receive cemiplimab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 21 days for up to 3 cycles in the absence of disease progression or unacceptable toxicity.

ADJUVANT PHASE: Within 2-6 weeks after completion of standard of care radiation therapy (or surgery if no radiation therapy), patients receive cemiplimab IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 18 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 12 weeks for 2 years, every 6 months for the next 3 years, and then annually for up to 10 years.

Primary Outcome Measures :
  1. Pathologic response rate [ Time Frame: From screening up to 10 years post-treatment ]
    Defined as the number of complete and partial responses divided by the total number of patients, as assessed by pathology. Pathological complete response (pCR) (no viable tumor) or pathological partial response (pPR) (less than 50% viable tumor) as well as near pCR (less than 10% viable tumor) in the tumor bed will be documented by pathology from the resection specimen. Pathologic response rate will be summarized using frequency and percentage, and a 95% exact confidence interval will be reported using the Clopper-Pearson method.


Secondary Outcome Measures :
  1. Time to local recurrence [ Time Frame: From screening to local recurrence, death, or last known follow-up, assessed up to 10 years post-treatment ]
    Local recurrence-free survival will be estimated using the Kaplan-Meier method.

  2. Time to systemic recurrence [ Time Frame: From screening to systemic recurrence, death, or last known follow-up, assessed up to 10 years post-treatment ]
    Systemic recurrence-free survival will be estimated using the Kaplan-Meier method.

  3. Overall survival (OS) [ Time Frame: From screening to death from any cause or last known follow-up, assessed up to 2 years post-treatment ]
    OS will be estimated using the Kaplan-Meier method. 6-month, 12-month, and 24-month OS estimates will be reported along with 95% confidence intervals.

  4. Recurrence-free survival (RFS) [ Time Frame: From screening to recurrence, death, or last known follow-up, assessed up to 2 years post-treatment ]
    RFS will be estimated using the Kaplan-Meier method. 6-month, 12-month, and 24-month RFS estimates will be reported along with 95% confidence intervals.


Other Outcome Measures:
  1. Change in immune system biomarkers [ Time Frame: From baseline up to 10 years post-treatment ]
    Pre- and post-surgery assessments of biomarkers extracted from tissue and blood samples will be summarized using frequencies and percentages for categorical variables, and mean, median, standard deviation, and range for numeric variables. Pre- versus (vs.) post-surgery values will be compared using paired t-tests or McNemar's tests, where appropriate. Biomarkers extracted from blood samples will also be collected at progression or completion of adjuvant therapy. In those cases, mixed models with a random intercept will be explored to assess the impact of time on change in biomarker status. Change in biomarker will be compared across response (yes/no) using two-sample t-tests or Mann Whitney U tests, where appropriate, and the and the impact of pre-surgery, post-surgery, and change in biomarker will be compared across survival endpoints using log-rank tests and univariate Cox proportional hazards models.

    • Anticoagulation is allowed only with low molecular weight heparin (LMWH). Patient receiving LMW heparin on stable therapeutic dose for more than 2 weeks or with factor Xa level < 1.1U/mL are allowed on the trial
  • Clinically significant toxic effect(s) of the most recent prior anti-cancer therapy must be grade 1 or resolved (except alopecia and sensory neuropathy); patients with grade 2 adrenal insufficiency related to prior anti-cancer therapy (defined as requiring medical intervention, such as concomitant steroids) or grade 2 hypothyroidism (defined as requiring hormone replacement therapy) may be enrolled provided that clinical symptoms are adequately controlled and the daily dose is 10 mg or less of prednisone or equivalent.

Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. A female of childbearing potential (FCBP) is a sexually mature woman who: has not undergone a hysterectomy or bilateral oophorectomy or has not been naturally postmenopausal for at least 12 consecutive months (if age >= 55 years); if the female subject is < 55 years and she has been naturally postmenopausal for >= 1 year her reproductive status has to be verified by additional lab tests (< 20 estradiol OR estradiol < 40 with follicle stimulating hormone [FSH] > 40 in women not on estrogen replacement therapy)
  • Patients must agree not to donate blood, sperm/ova while taking protocol therapy and for at least 6 months after stopping treatment

  • Other medications, or severe acute/chronic medical or psychiatric condition, or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, and in the judgment of the investigator would make the subject inappropriate for entry into this study
  • Clinical evidence of bleeding diathesis or coagulopathy
  • Subjects with a history of severe allergic reactions
  • Patients with prior malignancies, are eligible if they have been disease free for > 3 years
