Patients received 2 cycles of neoadjuvant chemo-NIVO therapy (docetaxel + cisplatin + NIVO) and CCRT (total dose 54-64 Gy). Post-CCRT, eligible patients were randomized 1:1 to receive consolidative NIVO (360 mg every 3 weeks for up to 12 months) or observation. The primary endpoint was progression-free survival (PFS) from randomization. Between December 3rd, 2019, and August 18th, 2023, 264 patients were enrolled, and 172 were randomized to NIVO consolidation (n = 86) or observation (n = 86). With a median follow-up of 22·8 months, NIVO consolidation resulted in significantly longer PFS than did observation (median not reached vs. 12.2 months [95% CI 10.2-20.8]; stratified hazard ratio 0·49 [95% CI 0.30-0.79], p = 0.003).

Treatment-related death occurred in 1 (1.2%) patient in the consolidation group because of pneumonitis. Patients with a high TMB had a longer PFS with consolidation (NR vs. 15.2 months, p = 0.042).
