Clinical study of aumolertinib versus osimertinib in the treatment of EGFR-mutated advanced non-small cell lung cancer
摘要
To compare the efficacy and safety of aumolertinib and osimertinib in the treatment of advanced non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations.
MethodsA retrospective analysis was performed for patients with EGFR-mutant NSCLC. The primary outcome was median progression-free survival (mPFS). Kaplan–Meier curves and the log-rank test were used to evaluate PFS and overall survival (OS), Cox regression was used for prognostic factors assessment.
ResultsA total of 202 patients were included, comprising 106 aumolertinib users and 96 osimertinib users. In the first-line treatment, no significant difference was observed in mPFS between aumolertinib and osimertinib group (19.0 months; hazard ratio [HR], 1.15; 95% confidence interval [CI], 0.70–1.91; P = 0.58). The disease control rate (DCR) (95.7% vs. 89.8%), objective response rate (ORR) (39.1% vs. 30.6%), and median OS (27.0 vs. 38.0 months) were comparable between the two groups, with no statistical significance. In the second-line treatment, aumolertinib and osimertinib demonstrated similar mPFS (13.5 vs. 13.0 months; HR, 1.13; 95% CI, 0.75–1.71; P = 0.55), DCR (90.0% vs. 87.2%), ORR (16.7% vs. 17.0%), and median OS (24.0 vs. 20.0 months). Adverse events of grade 1–2 were also similar between the two groups. Cox regression revealed that performance status (P < 0.001) and the treatment lines of aumolertinib/osimertinib (P = 0.015) were independent prognostic factors.
ConclusionAumolertinib and osimertinib exhibit comparable efficacy and safety profiles in the treatment of EGFR-mutant NSCLC, providing a reference path for clinicians to optimize drug treatment strategies in NSCLC.
