Description:
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

Purpose
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
Detailed Description
Primary Objective:
To assess safety and estimate 1-year 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. For those participants for whom tumor tissue is available, we will evaluate the tumor
microenvironment (TME), and immune markers at the invasive margin of the tumor,
including CD8, PD-1, PD-L1, T-cell immunoglobulin and mucin-domain containing-3
(TIM-3), galectin-9 or high-mobility group protein 1 (HMGB-1), B- and T- lymphocyte
attenuator (BTLA) and herpes virus entry mediator (HVEM), as well as
lymphocyte-activation gene 3 (Lag-3), cytotoxic T-lymphocyte-associated protein 4
(CTLA-4) and others.
4. If sufficient tumor is available, we will also evaluate the genomic and/or
transcriptomic profile of a subset of 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.

Primary Outcome Measures
Measure: | Number of subjects with dose limiting toxicities |
Time Frame: | Up to 20 weeks post treatment |
Safety Issue: | |
Description: | There will be 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 |
