IMpower150 Final Exploratory Analyses for Atezolizumab Plus Bevacizumab and Chemotherapy in Key NSCLC Patient Subgroups With EGFR Mutations or Metastases in the Liver or Brain
Open accessAbstract
INTRODUCTION Final overall survival (OS) analyses are presented for EGFR mutations and liver or brain metastases subgroups in the phase III IMpower150 study (NCT02366143) evaluating atezolizumab+bevacizumab+carboplatin/paclitaxel (ABCP) or atezolizumab+carboplatin/paclitaxel (ACP) vs bevacizumab+carboplatin/paclitaxel (BCP). METHODS Overall, 1202 patients (intention-to-treat [ITT] population) with chemotherapy-naive, metastatic, nonsquamous non-small cell lung cancer were randomized to ABCP, ACP or BCP. Patients with treated, stable brain metastases were permitted. OS was assessed in EGFR mutations and baseline liver metastases subgroups; rate and time to development (TTD) of new brain metastases was assessed in ITT patients. RESULTS At data cutoff (September 13, 2019; median follow-up, 39.3 months), OS improvements were sustained with ABCP versus BCP in sensitizing EGFR mutations (all: hazard ratio [HR] 0.60; 95% CI: 0.31-1.14; prior tyrosine kinase inhibitor [TKI]: HR 0.74; 95% CI: 0.38-1.46) and baseline liver metastases (HR 0.68; 95% CI: 0.45-1.02) subgroups. ACP did not show survival benefit versus BCP in sensitizing EGFR mutations (all: HR 1.0; 95% CI: 0.57-1.74; prior TKI: HR 1.22; 95% CI: 0.68-2.22) or liver metastases (HR 1.01; 95% CI: 0.68-1.51) subgroups. Overall, 100 patients (8.3%) developed new brain metastases. While not formally evaluated, an improvement toward delayed TTD was seen with ABCP vs BCP (HR, 0.68; 95% CI: 0.39-1.19). CONCLUSIONS This final exploratory analysis showed OS benefits for ABCP versus BCP in patients with sensitizing EGFR mutations, including those with prior TKI failures, and with liver metastases, although these results should be interpreted with caution. The impact of ABCP on delaying the development of new brain lesions requires further investigation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
