Summary
We propose a window of opportunity trial to evaluate safety and efficacy of a short course of
the study combination, composed by an Anti-PD-1 monoclonal antibody (Dostarlimab (TSR-042))
and a PARPi (Niraparib). The study population will be surgically resectable, HPV-negative
(defined by p16 negative status) locally advanced HNSCC.
Maintenance treatment will be then delivered, so to better integrate the therapeutic benefits
of this drug combination.
Response to neoadjuvant treatment will be evaluated by the rate of major pathologic response,
morphologic, and functional imaging (MRI with functional evaluation -DWI).
We anticipate that neoadjuvant and maintenance PARPi plus immunotherapy treatment could lead
to a reduction of loco-regional recurrence (LRR) and distant metastasis (DM) rates in such a
high-risk population.
Furthermore, the window of opportunity portion of this trial will allow in vivo acquisition
of valuable knowledge on mechanisms of action and primary resistance to Anti-PD-1 monoclonal
antibody and PARPi in HNSCC. In this phase of the study, biological specimens will be
collected (pre-treatment tumor biopsy, tissues from the surgical specimen, liquid biopsy,
blood and saliva samples) as well as functional imaging (MRI).
