Brief Summary:

A small group of skin cancers of the head and neck, called resected cutaneous squamous carcinomas, are more aggressive than most cancers of this type, even after being treated with standard therapy. This trial will use stronger treatment to look at the safety and effectiveness (efficacy) of combining a drug called Pembrolizumab with radiation after a cancer has already been treated to suppress secondary tumor formation in high risk cutaneous squamous cell cancer of the head and neck.

Primary Objective To assess safety by looking at the people with dose limiting responses


Condition or disease Intervention/treatment Phase
Squamous Cell Carcinoma of the Head and Neck Drug: Pembrolizumab Radiation: IMRT 60-66Gy Phase 2

Detailed Description:

Primary Objective:

To assess safety and estimate 1-year progression-free survival (PFS) of postoperative radiation therapy (RT) + concurrent and adjuvant Pembrolizumab in high risk resected cutaneous squamous cell cancer of the head and neck (cSCC-HN).

Secondary Objectives

  1. To evaluate the relationship of baseline programmed death-ligand 1 (PD-L1) expression by tumor and tumor-infiltrating lymphocytes (TILs) to preliminary efficacy .
  2. To phenotype tumor infiltrating lymphocytes and peripheral blood lymphocytes (PBLs), and investigate tumor suppressor populations including Tregs, myeloid-derived suppressor cells (MDSCs) and cluster of differentiation 8 (CD8) suppressor cells and assess ex vivo for effector function by cytokine production and cytotoxicity assays as well as suppressor function in assays with autologous PBLs.
  3. To evaluate the tumor microenvironment (TME), and immune markers at the invasive margin of the tumor, including CD8, PD-1, PD-L1, TIM-3, galectin-9 or HMGB-1, BTLA and HVEM, as well as Lag-3, CTLA-4 and others.
  4. To evaluate the genomic and/or transcriptomic profile of these tumors using RNA-seq /Whole Transcriptome Shotgun Sequencing

Trial Design:

This is a phase II trial evaluating the addition of concurrent and adjuvant fixed-dose pembrolizumab in combination with standard intensity-modulated radiation therapy (IMRT), in order to establish safety and estimate efficacy of this regimen to be tested in a subsequent randomized registration trial.

Thirty seven patients will be enrolled.

Arm Intervention/treatment
Experimental: Pembrolizumab + post operative radiotherapy
IMRT 60-66Gy for 6 weeks in combination with Pembrolizumab every 3 weeks for 16 weeks
Drug: Pembrolizumab
200mg every 3 weeks for 16 weeks given by IV infusion

Radiation: IMRT 60-66Gy
60-66Gy for 6 weeks




Primary Outcome Measures :
  1. Number of Subjects With Dose Limiting Toxicities [ Time Frame: Up to 20 weeks post treatment ]
    There will be an initial safety run in cohort consisting of an initial safety run in cohort consisting of eight patients to allow for at least six evaluable patients for dose limiting toxicities (DLTs) by the week 20 visit. If a total of 0-2 of the initial six evaluable patients experience DLTs, the safety run in will have been deemed successful and the 29 remaining planned patients will be accrued. DLT for this study is defined as the occurrence of a severe adverse event (AE) that is at least possibly related to pembrolizumab, and occurs from the initiation of treatment thru 30 days after the final administration of the study treatment

  2. Progression Free Survival [ Time Frame: Up to 1 year after beginning treatment ]
    Progression-free survival (PFS) will be calculated from treatment initiation to disease progression or death from any cause or last follow up

Criteria

Inclusion Criteria:

  • Histologic diagnosis of cutaneous squamous cell carcinoma of the head and neck that has been resected with no evidence of gross residual disease (margin positivity is acceptable)
  • Patients must have undergone resection of the disease and demonstrate high risk pathologic features including:

    • T4
    • Node positive disease
    • T2/T3N0 disease with any 1 additional feature, including:

      • Recurrent Disease
      • Perineural invasion
      • Lymphovascular space invasion
      • Poorly differentiated histology
      • Positive Margins
      • Satellitosis or in-transit metastases
  • Patients are required to have computerized tomography (CT) neck and chest or positron emission tomography/computerized tomography (PET/CT) and have no documented evidence of distant metastases
  • Patients must not have a history of the following immunosuppressive conditions:bone marrow transplantation and/or organ transplants and/or chronic rheumatic conditions that require active immunosuppressive therapy. Patients with a history of chronic lymphoid or leukemic malignancies which are not under active therapy (no active therapy within the last 3 months) will be eligible. Patients with chronic lymphoid or leukemic malignancies are eligible with or without active disease as long as they have not had treatment within the past three months.
  • Patients may not have had prior therapy with a checkpoint inhibitor (e.g. anti-CTLA-4, anti-PD-1 or anti-PD-L1 therapy)
  • Patients may not have had prior radiotherapy (>30Gy) to the area requiring treatment that would result in any overlap of tissue in both fields
