Brief summary

The purpose of this study is to determine the best overall response of the combination of dostarlimab and niraparib in patients with recurrent and/or metastatic HNSCC patients.

Detailed description

Recurrent and/or metastatic HNSCC patients will be treated with combination of the PD-1 inhibitor (dostarlimab) and PARPi (niraparib) concurrently and ORR, PFS and OS will be determined.
