- Overall Response [ Time Frame: 8 weeks ]Measured by assessing best overall response using RECIST 1.1 in subjects in recurrent and/or metastatic HNSCC patients receiving combination of niraparib and dostarlimab.
- Rate of all Adverse Events [ Time Frame: 30 days after completion of treatment ]As determined by CTCAE v5.0 in subjects with recurrent and/or metastatic HNSCC receiving combination of niraparib and dostarlimab.
- Progression Free Survival [ Time Frame: 1 and 3 years ]Measured using Kaplan Meier Curves from time of treatment start until time of progression
- Overall Survival [ Time Frame: 5 years ]Measured using Kaplan Meier Curves from diagnosis until time of death
