Summary
Primary Outcome Measures: 1. Overall survival (OS) [ Time Frame: From randomization to death, assessed up to 10 years ] Log rank test will be used to compare OS. As patients on the observation arm are allowed to cross-over to the nivolumab arm upon progression, an overall survival analysis using inverse probability censoring weights (IPCW, Robins et. al, 2000) will also be considered. Kaplan-Meier method and Cox regression will be used for the survival outcome analyses. 2. Negative (standardized qualitative) 12 week post therapy (cisplatin + radiation therapy [RT]) FDG positron emission tomography/computed tomography (PET/CT) associated with OS for patients who have a PET/CT [ Time Frame: At 12 weeks post therapy ] Logrank tests and input hazard rates will be used. 3. Negative (standardized qualitative) 12 week post therapy (cisplatin + RT) FDG PET/CT associated with PFS for patients who have a PET/CT [ Time Frame: At 12 weeks post therapy ] Logrank tests and input hazard rates will be used. Secondary Outcome Measures: 1. Progression-free survival (PFS) [ Time Frame: From randomization to date of progression, second primary tumor from the head and neck region, or death, assessed up to 10 years ] Progression will be defined using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria. The comparison of PFS will use stratified log rank test and will be intent-to-treat analyses. 2. Prognostic effect of baseline PD-L1 expression (positive versus [vs.] negative) on OS and PFS [ Time Frame: Baseline up to 10 years ] Chi-square testing or Pearson correlation testing will be used for the secondary correlation analyses. 3. Prognostic effect of baseline saliva and/or plasma human papillomavirus (HPV) status (positive vs. negative) on OS and PFS [ Time Frame: Baseline up to 10 years ] Saliva and plasma HPV status at 12 weeks and 9 months following completion of concurrent therapy will also be analyzed regarding effect on outcome. Chi-square testing or Pearson correlation testing will be used for the secondary correlation analyses. 4. Prognostic value of maximum standardized uptake value (SUVmax) of primary tumor or neck nodal metastasis of baseline FDG PET/CT for OS [ Time Frame: Baseline up to 10 years ] Chi-square testing or Pearson correlation testing will be used for the secondary correlation analyses. 5. Prognostic value of SUVmax of primary tumor or neck nodal metastasis of baseline FDG PET/CT for PFS [ Time Frame: Baseline up to 10 years ] Chi-square testing or Pearson correlation testing will be used for the secondary correlation analyses. 6. SUVmax of primary tumor or nodal metastasis of baseline FDG PET/CT with PDL1 expression (positive vs. negative) [ Time Frame: Baseline up to 10 years ] Chi-square testing or Pearson correlation testing will be used for the secondary correlation analyses. 7. Post therapy (cisplatin + RT) FDG PET/CT with saliva or plasma levels of HPV deoxyribonucleic acid (DNA) [ Time Frame: Up to 9 months post-therapy ] Chi-square testing or Pearson correlation testing will be used for the secondary correlation analyses. 8. PET based therapy response assessment compared to RECIST 1.1 assessment for patients who have a PET/CT scan at 12 weeks [ Time Frame: At 12 weeks post chemoradiation therapy ] Kappa statistics will be applied to evaluate the agreement between PET based therapy response assessment (Hopkins criteria) and RECIST 1.1 assessment at 12 weeks post chemoradiation therapy.
