A Pilot Study to Evaluate Immunological Response to PD-1 Inhibition in Squamous Cell Carcinoma of the Head and Neck (SCCHN)
This is a single-center cross-sectional imaging and correlative biomarker study in patients
with Squamous Cell Carcinoma of the Head and Neck (SCCHN). Cohort 1 will be patients with
unresectable or metastatic SCCHN cancer receiving standard of care (SOC) anti-PD-1 treatment
and Cohort 2 will be neoadjuvant study participants who will receive one dose of anti-PD-1
treatment prior to tumor resection or radiation. Blood sampling and tissue biopsies will be
collected from both cohorts and both cohorts will undergo two whole body PET(Positron
Emission Tomography)/CT(Computed Tomography) imaging with [18F]F-AraG. First scan prior to
initiating anti-PD-1 treatment and second scan post initiation of anti-PD-1 treatment in
Cohort 1 and prior to tumor resection or radiation in Cohort 2
with Squamous Cell Carcinoma of the Head and Neck (SCCHN). Cohort 1 will be patients with
unresectable or metastatic SCCHN cancer receiving standard of care (SOC) anti-PD-1 treatment
and Cohort 2 will be neoadjuvant study participants who will receive one dose of anti-PD-1
treatment prior to tumor resection or radiation. Blood sampling and tissue biopsies will be
collected from both cohorts and both cohorts will undergo two whole body PET(Positron
Emission Tomography)/CT(Computed Tomography) imaging with [18F]F-AraG. First scan prior to

Cohort 1 and prior to tumor resection or radiation in Cohort 2

initiating anti-PD-1 treatment and second scan 6-12 weeks post initiation of anti-PD-1
treatment in Cohort1 and within 2-3 weeks of administration of one dose of anti-PD-1 in
Cohort 2.
This study will help us assess if [18F]F-AraG can be used for noninvasive imaging and
assessment of T cell activation and expansion in the tumor microenvironment. Specifically, we
will be assessing if there is a correlation between an increase in the imaging signal and an
increase in T cell activation (measured directly from the T cells obtained from biopsy
specimens).
Patients and care providers will not be blinded to any part of this study. Patients will be
evaluated one day and one week via telephone visit after each radiopharmaceutical injection
for safety follow-up. All adverse events will be recorded. Due to the noninvasive and
non-therapeutic nature of the study, potential risks of the study are anticipated to be low.
