Efficacy and safety of Osimertinib and other third-generation EGFR TKIs in advanced NSCLC: a systematic review and meta-analysis
Year: 2026
Type: review
Study designs: Systematic Review, Meta-Analysis
Abstract: OBJECTIVE: To systematically evaluate the clinical efficacy, safety, and prognostic impact of third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs), particularly osimertinib, in patients with advanced non-small cell lung cancer (NSCLC). METHOD: A comprehensive search of international and Chinese databases was conducted from inception to April 2025 to identify randomized controlled trials (RCTs) assessing osimertinib in advanced NSCLC. Data extraction and quality assessment were performed independently by two reviewers using the Cochrane Handbook (version 5.3). Meta-analysis was conducted using RevMan 5.4. RESULT: Nine RCTs involving 1,880 patients were included. Osimertinib significantly improved objective response rate (ORR) [OR = 2.99, 95% CI: 1.87–4.77] and disease control rate (DCR) [OR = 2.80, 95% CI: 1.38–5.67] compared to control therapies. The incidence of grade ≥ 3 adverse events was significantly lower in the osimertinib group [OR = 0.26, 95% CI: 0.14–0.47]. Osimertinib increased the risk of dermatologic events such as paronychia and rash but decreased gastrointestinal symptoms including nausea and vomiting. CONCLUSION: Osimertinib is an effective and generally well-tolerated treatment option for patients with advanced NSCLC. While efficacy and safety are favorable, further research is needed to assess long-term outcomes and monitor serious adverse events.
