Brief Summary:
This phase II trial studies how well cemiplimab before surgery works in treating patients with skin cancer that is high-risk and has not spread to other parts of the body (localized), has come back locally (locally recurrent), or has spread regionally (regionally advanced), and can be removed by surgery (resectable). 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.

Detailed Description:

PRIMARY OBJECTIVE:

I. To assess the pathological partial response (PPR) rate in patients with potentially resectable cutaneous squamous cell carcinoma (CSCC) treated with neoadjuvant cemiplimab.

SECONDARY OBJECTIVES:

I. To estimate the pathological complete response rate (PCR). II. To estimate the Response Evaluation Criteria in Solid Tumors (RECIST) (version [v]1.1) 9 week objective response rate (ORR).

III. To estimate the RECIST (v1.1) 12 month progression free (PFS). IV. To assess the toxicity among patients with CSCC treated with neoadjuvant cemiplimab.

EXPLORATORY OBJECTIVES:

I. To evaluate tumor mutational burden (TMB) and correlate with response to PD-1 blockade therapy.

II. To evaluate PD-L1 expression on CSCC tumor cells and correlate with response to PD-1 blockade.

III. To evaluate CD8+ T cell infiltration into CSCC tumors and correlate with response to PD-1 blockade.

IV. To assess other adaptive immune resistance mechanisms in CSCC tumors.

OUTLINE:

Patients receive cemiplimab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 21 days for up to 3 cycles (or up to 4 cycles for patients whose disease is unresectable after 3 cycles) in the absence of disease progression or unacceptable toxicity. Within 6 weeks of last dose of therapy, patients with potentially resectable tumors undergo surgical resection.

After completion of study treatment, patients are followed up every 3 months for 24 months.

Primary Outcome Measures :
  1. Confirmed pathologic partial response [ Time Frame: Up to 24 months after completion of study treatment ]
    Defined by presence of < 50% malignant cells. Descriptive statistics will be used to summarize the measurements.


Secondary Outcome Measures :
  1. Pathologic complete response rate [ Time Frame: Up to 24 months after completion of study treatment ]
    Descriptive statistics will be used to summarize the measurements.

  2. Objective response rate [ Time Frame: At 9 weeks ]
    Measured by Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1. Descriptive statistics will be used to summarize the measurements.

  3. Progression-free survival [ Time Frame: From start of treatment to time of progression or death whichever comes first, assessed at 12 months ]
    Measured by RECIST v1.1. Descriptive statistics will be used to summarize the measurements.

  4. Incidence of toxicities [ Time Frame: Up to 24 months after completion of study treatment ]
    All toxicities will be summarized and graded according to maximum grade by Common Terminology Criteria for Adverse Events v4. Descriptive statistics will be used to summarize the measurements.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Histologically confirmed, cutaneous squamous cell carcinoma
  • Patients must have disease that is deemed potentially resectable, at the time of the start of study, by the treating investigator. The decision to perform surgery on patients must be based on good clinical judgment. Eligible patients for surgical resection must have disease that, in the judgment of the surgeon, is deemed potentially resectable, resulting in free surgical margins
  • Patients must have measurable disease
  • Patients must have disease that is considered either: (1) high-risk localized CSCC, (2) locally recurrent CSCC, or (3) regionally advanced CSCC. The criteria specific to each of these populations is listed below

    • For patients with high-risk localized CSCC, at least two of the following clinical or pathologic high-risk features must be present to be eligible:

      • Clinical risk factors

        • Any tumor size > 2.0 cm in diameter
        • Tumors > 1.0 cm in high risk locations, including "mask areas" (central face, eyelids, eyebrow, nose, lips [cutaneous], periorbital, chin, mandible, preauricular and postauricular skin/sulci, genitalia, hands, feet, cheek, forehead, scalp, neck and pretibial)
        • Any rapidly growing and/or symptomatic tumor
      • Pathologic risk factors

        • Poorly differentiated histology
        • Depth > 6 mm in thickness
        • Acantholytic / adenoid, adenosquamous, desmoplastic, or metaplastic / carcinosarcomatous histologic subtypes
        • Invasion beyond subcutaneous fat
        • Perineural, lymphatic, or vascular involvement

  • Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 90 days following completion of therapy. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. A female of child-bearing potential is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:

  • Active autoimmune disease requiring systemic treatment in the past 2 years (i.e. use of disease modifying agents or immunosuppressive drugs). Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc) is not considered a form of systemic treatment
  • History of other prior malignancy in the last five years, with the exception of: adequately treated non-melanoma skin cancers (including multiple primary skin cancers), adequately treated in situ cancer, and other local tumors considered cured by local treatment (including melanoma)
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to cemiplimab or any other PD-1 or PD-L1 inhibitor
