New Protocol: Adjuvant Nivolumab with CISplatin Concurrently with Radiotherapy for Head and Neck Cancer

Adding nivolumab to cisplatin and radiotherapy significantly improved disease-free survival for high-risk resected LA-SCCHN. Nivolumab reduced locoregional relapses with a moderate increase in grade 3 and 4 adverse events, showing a favorable risk-to-benefit ratio.

  • Study

    Randomised, open-label, phase 3 trial [GORTEC 2018-01 NIVOPOST-OP].
    High-risk resected locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN).
    Nivolumab, cisplatin, and radiotherapy (n=332) vs cisplatin and radiotherapy (n=334).



  • Efficacy

    3yr DFS: 63.1% vs 52.5% (Nivolumab vs. placebo) (HR 0.76 [0.60-0.98])
    3yr Locoregional relapse: 12.9% vs 19.8% (HR 0.63 [0.42-0.94])
    3yr Distant relapse: 12.6% vs 13.2%.



  • Safety

    Grade >=3 AEs: 73% vs 68%
    Grade 4 AEs: 10% vs 5%
    Serious AEs: 33% vs 19%
