The objective response rate of 53.3% (95% CI 45.1–57.8) in the ACN group was higher than the 29.7% (26.1–32.8) observed in the CN group (p = 0.008) (Table 2). For patients in the ACN group, the ORR was 11.7%, 18.3%, and 23.3% for cohorts TC1, TC2, and TC3, respectively....Subgroup analyses demonstrated that for individuals with TC3 PD-L1-expressing cells, the median OS was 23.7 months in the ACN group versus 16.1 months in the CN group (HR 0.25; p = 0.001)....The findings of this study demonstrate that the atezolizumab plus carboplatin and nab-paclitaxel regimen as front-line management might provide greater survival benefits in PD-L1-positive metastatic nonsquamous NSCLC patients in a selected population than the carboplatin and nab-paclitaxel regimen, with a tolerable safety profile.
