    • Time Frame: Between baseline and until 3 months (at the end of chemoradiation)
    • the rate of patients : (1) who can receive the 2 nivolumab infusions planned at D1 and between D14 to D16 among patients in the experimental arm And (2) who can receive chemoradiation at D30 (-2 /+7) after the second nivolumab infusion, without delay of more than 7 days with respect to the planned start of chemoradiation (RT-CT) among patients in the experimental arm And (3) with no radiotherapy break of one week or more, among patients in the experimental arm and patients in the control arm separately And (4) with minimal dose of radiotherapy (dose received >95% of theoretical dose) among patients in the experimental arm and patients in the control arm separately And (5) with minimal dose of chemotherapy of ≥200 mg/m² of cisplatin (CDDP) among patients in the experimental arm and patients in the control arm separately

Secondary Measures

  • The incidence of Adverse Events related or not related to chemoradiation and Nivolumab
    • Time Frame: During treatment phase and until 90 days after the last fraction of radiotherapy
    • Acute and delayed toxicities assessed according to national cancer institute (NCI) common terminology criteria for adverse events (CTCAE) version 5.0
  • Objective Response Rate in the experimental arm
    • Time Frame: Between baseline and up to 17 days after the second infusion of nivolumab
    • Radiological response will be assessed according to RECIST 1.1.
  • Tumor Response in both arms
    • Time Frame: Between baseline and 3 months after the end of chemoradiation
    • Radiological response will be assessed according to RECIST 1.1.
  • Overall Survival (OS)
    • Time Frame: Between baseline and 2 years after the end of chemoradiation
    • the time from randomization to death from any cause
  • Locoregional control (LRC)
    • Time Frame: Between baseline and 2 years after the end of chemoradiation
    • the absence of disease progression (radiological progression according to RECIST 1.1 or clinical progression) or recurrence at the site of the primary tumor and loco-regional lymph nodes.
  • Progression-Free Survival (PFS)
    • Time Frame: Between baseline and 2 years after the end of chemoradiation
    • The time from randomization to progression or death from any cause
  • Objective Response Rate in the experimental arm
    • Time Frame: Between baseline and up to 17 days after the second infusion of nivolumab
    • Standardized uptake value (SUV) evolution will be assessed by positron emission tomography (PET)-scan.
  • Tumor Response in both arms
    • Time Frame: Between baseline and 3 months after the end of chemoradiation
    • SUV evolution will be assessed by PET-scan.
