About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Nodal disease with extracapsular extension (ECE) and at least one node >= 20 mm on the surgical pathology report

In-transit metastases (ITM) defined as skin or subcutaneous metastases that are > 2 cm from the primary lesion but are not beyond the regional nodal basin

T4 lesion for head and neck CSCC

Perineural invasion (PNI), defined as clinical and/or radiologic involvement of named nerves

Disqualifiers

Determined not to be a surgical candidate due to medical co-morbidities or extent of disease

Treatment with chronic immunosuppressants (e.g., cyclosporine following transplantation)

Prior organ allograft or allogeneic bone marrow transplantation

Subjects with active or history of immune mediated pneumonitis, colitis, hepatitis, nephritis, or skin reactions as these patients may be at increased risk for developing immune therapy-induced exacerbation or recurrence of their immune mediated disease, potentially delaying surgery

Trial outcomes

Primary outcomes

1

Pathologic response rate

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.

Time frame
From screening up to 10 years post-treatment

Secondary outcomes

1

Time to local recurrence

Local recurrence-free survival will be estimated using the Kaplan-Meier method.

Time frame
From screening to local recurrence, death, or last known follow-up, assessed up to 10 years post-treatment
2

Time to systemic recurrence

Systemic recurrence-free survival will be estimated using the Kaplan-Meier method.

Time frame
From screening to systemic recurrence, death, or last known follow-up, assessed up to 10 years post-treatment
3

Overall survival (OS)

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.

Time frame
From screening to death from any cause or last known follow-up, assessed up to 2 years post-treatment
4

Recurrence-free survival (RFS)

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.

Time frame
From screening to recurrence, death, or last known follow-up, assessed up to 2 years post-treatment

Other outcomes

1

Change in immune system biomarkers

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.

Time frame
From baseline up to 10 years post-treatment
