Overall survival with adjuvant atezolizumab after chemotherapy in resected stage II-IIIA non-small cell lung cancer (IMpower010): a randomised, multicentre, open-label, phase 3 trial.

Although OS remains immature for the ITT population, these data indicate a positive trend favouring atezolizumab in PD-L1 subgroup analyses, primarily driven by the PD-L1 TC ≥50% stage II-IIIA subgroup. No new safety signals were observed after 13 months' additional follow-up. Together, these findings support the positive benefit-risk profile of adjuvant atezolizumab in this setting.
