Abstract Background The global Phase III IMpower132 study evaluating atezolizumab plus pemetrexed and carboplatin or cisplatin (APP) versus pemetrexed plus carboplatin or cisplatin (PP) for first‐line treatment of non‐squamous advanced non‐small cell lung cancer (NSCLC) met its co‐primary progression‐free survival (PFS) endpoint at the primary analysis in the intention‐to‐treat (ITT) population. Although the co‐primary overall survival (OS) endpoint was not met, numerical OS improvement favoring APP over PP was observed at the final analysis. We report primary results for Chinese patients in IMpower132. Methods Treatment‐naive Chinese patients with non‐squamous stage IV EGFR/ALK mutation‐negative NSCLC were randomized 1:1 to receive 4 or 6 cycles of APP or PP, followed by maintenance atezolizumab plus pemetrexed or pemetrexed. Co‐primary endpoints were investigator‐assessed PFS and OS. Results The ITT population included 163 Chinese patients (82 in the APP arm and 81 in the PP arm). At data cutoff (median follow‐up, 11.7 months), the median PFS in the APP and PP arms was 8.3 and 5.8 months, respectively; the unstratified hazard ratio (HR) was 0.73 (95% CI: 0.50, 1.08). At the interim OS analysis, median OS was not estimable in either arm; the unstratified HR was 0.70 (95% CI: 0.40, 1.24). No new safety signals were observed. Conclusion Among Chinese patients in IMpower132, PFS benefit was seen with APP versus PP. Though interim OS data were immature, there was a trend toward OS benefit favoring APP versus PP. The safety profile of the APP was consistent with the known risks of the individual treatment components. ClinicalTrials.gov: NCT02657434. |
