The efficacy and safety of Nivolumab in combination with docetaxel and Nivolumab in patients. Qualified patients were stratified by histological type (squamous cell carcinoma vs. non-squamous cell carcinoma) randomized to receive the following regimen in a 1:1 ratio: Group A: Nivolumab 300mg + docetaxel 75mg/m2 IV q3w Group B: Nivolumab 200mg IV q2w All patients were evaluated for tumor at baseline, and tumor evaluations were performed every 6 weeks within 48 weeks after randomization (regardless of whether dosing was delayed).
