Abstract

Introduction: The role of bevacizumab combined with paclitaxel and carboplatin in the first-line treatment of advanced non-squamous non-small-cell lung cancer (NSCLC) has been supported by a large number of data. However, whether bevacizumab biosimilars have the same efficacy and safety as the original drug is still controversial. This meta-analysis was designed to evaluate whether bevacizumab biosimilars have the same clinical efficacy and safety as the original drug in patients with advanced non-squamous NSCLC. Methods: Electronic databases (PubMed, Embase, Cochrane, CNKI, Wanfang, and VIP) and the ClinicalTrail.gov website were extensively searched using relevant search criteria. We included phase III randomized controlled trials (RCTs) to compare the efficacy and safety of marketed biosimilars and Avastin in the first-line treatment of patients with advanced NSCLC. The risk of bias of the included studies was assessed using the RoB 2 assessment scale, and the RevMan 5.4 statistical software was used for meta-analysis. Results: A total of 6360 patients were included in 11 RCTs. There was no statistical difference between the experimental group and the control group in terms of effectiveness [objective response rate (at week 18), disease control rate (at week 18), median duration of response, median progression-free survival, median overall survival (OS), and OS after 12 months]. In terms of safety [treatment-emergent adverse events (grade ⩾3) and treatment-related adverse events (grade ⩾3)], there was also no significant difference between biosimilars and Avastin. Conclusions: The efficacy and safety of bevacizumab biosimilars in the treatment of advanced non-squamous NSCLC are highly similar to those of the original drug combined with paclitaxel and carboplatin, respectively.
