We report DFS final analysis, second overall survival (OS) interim analysis, and safety with a ≥5-year follow-up. Patients with completely resected stage IB-IIIA NSCLC were randomly assigned to atezolizumab (1,200 mg once every 3 weeks, 16 cycles) or BSC after platinum-based chemotherapy. At clinical cutoff (January 26, 2024), stratified hazard ratios (HRs; 95% CI) for DFS were 0.85 (95% CI, 0.71 to 1.01; P = .07) in the intention-to-treat (n = 1,005), 0.83 (95% CI, 0.69 to 1.00) in the all-randomized stage II-IIIA (n = 882), and 0.70 (95% CI, 0.55 to 0.91) in stage II-IIIA PD-L1 tumor cell (TC) ≥1% (n = 476) populations. Stratified HRs (95% CI) for OS were 0.97 (95% CI, 0.78 to 1.22), 0.94 (95% CI, 0.75 to 1.19), and 0.77 (95% CI, 0.56 to 1.06), respectively. The unstratified HRs (95% CI) in the stage II-IIIA PD-L1 TC ≥50% population (n = 229) were 0.48 (95% CI, 0.32 to 0.72) for DFS and 0.47 (95% CI, 0.28 to 0.77) for OS, and the unstratified HRs in the stage II-IIIA PD-L1 TC ≥50% without EGFR/ALK alterations (n = 209) population were 0.49 (95% CI, 0.32 to 0.75) and 0.44 (95% CI, 0.26 to 0.74). No new safety signals were reported. IMpower010 is the first study to report survival outcomes with a ≥5-year follow-up and continued to show benefit with atezolizumab versus BSC after adjuvant chemotherapy in patients with resected stage II-IIIA PD-L1–selected NSCLC.
