Here, we report the efficacy of ABCP or atezolizumab plus carboplatin plus paclitaxel (ACP) versus BCP in key patient subgroups.MethodsIMpower150 was a randomised, open-label, phase 3 study done at 240 academic medical centres and community oncology practices across 26 countries worldwide. Patients with chemotherapy-naive metastatic non-small-cell lung cancer were randomly assigned (1:1:1) to receive ABCP, ACP, or BCP every three weeks. The co-primary endpoints were overall survival and investigator-assessed progression-free survival in intention-to-treat wild-type patients (patients with epidermal growth factor receptor [EGFR] or anaplastic lymphoma kinase [ALK] genetic alterations were excluded). Efficacy was assessed in ke...
