IMpower210: A phase III study of second-line atezolizumab vs. docetaxel in East Asian patients with non-small cell lung cancer.
Objective: IMpower210 (NCT02813785) explored the efficacy and safety of single-agent atezolizumab vs. docetaxel as second-line treatment for advanced non-small cell lung cancer (NSCLC) in East Asian patients.
Methods: Key eligibility criteria for this phase III, open-label, randomized study included age ≥18 years; histologically documented advanced NSCLC per the Union for International Cancer Control/American Joint Committee on Cancer staging system (7th edition); Eastern Cooperative Oncology Group performance status of 0 or 1; and disease progression following platinum-based chemotherapy for advanced or metastatic NSCLC. Patients were randomized 2:1 to receive either atezolizumab (1,200 mg) or docetaxel (75 mg/m2). The primary study endpoint was overall survival (OS) in the intention-to-treat (ITT) population with wild-type epidermal growth factor receptor expression (ITT EGFR-WT) and in the overall ITT population.
Results: Median OS in the ITT EGFR-WT population (n=467) was 12.3 [95% confidence interval (95% CI), 10.3-13.8] months in the atezolizumab arm (n=312) and 9.9 (95% CI, 7.8-13.9) months in the docetaxel arm [n=155; stratified hazard ratio (HR), 0.82; 95% CI, 0.66-1.03]. Median OS in the overall ITT population was 12.5 (95% CI, 10.8-13.8) months with atezolizumab treatment and 11.1 (95% CI, 8.4-14.2) months (n=377) with docetaxel treatment (n=188; stratified HR, 0.87; 95% CI, 0.71-1.08). Grade 3/4 treatment-related adverse events (TRAEs) occurred in 18.4% of patients in the atezolizumab arm and 50.0% of patients in the docetaxel arm.
Conclusions: IMpower210 did not meet its primary efficacy endpoint of OS in the ITT EGFR-WT or overall ITT populations. Atezolizumab was comparatively more tolerable than docetaxel, with a lower incidence of grade 3/4 TRAEs.
