Abstract
Background
Osimertinib may improve the prognosis of patients with epidermal growth factor receptor (EGFR) T790M-mutated non-small cell lung cancer (NSCLC); however, to date, the efficacy and safety of osimertinib plus bevacizumab have not been elucidated.
Objective
We aimed to investigate the additional effect of bevacizumab plus osimertinib compared with osimertinib alone in NSCLC patients with EGFR T790M mutation.
Methods
In this study, 32 patients received osimertinib alone, while 20 patients received osimertinib plus bevacizumab. The median follow-up was 12 months. Overall survival (OS) and progression-free survival (PFS) were estimated and adverse events (AEs) were compared.
Results
The overall response rate (ORR) was higher in the combination group than in the osimertinib-alone group (70.0% vs. 43.8%), and the OS (12.8% ± 7.7% vs. 45.4% ± 12.0%; p = 0.038) and PFS (37.3% ± 11.9% vs. 55.3% ± 14.3%; p = 0.045) were also significantly improved in patients who underwent osimertinib plus bevacizumab. Furthermore, the incidence of hypertension was significantly higher in the combination arm when compared with osimertinib alone (p = 0.003), and the number of other AEs were not significantly increased by adding bevacizumab (all p > 0.05).
Conclusion
Concomitant use of bevacizumab and osimertinib in NSCLC patients with EGFR T790M mutation may have potential therapeutic effect than osimertinib alone. Further studies with a larger number of patients are warranted to confirm results of this study.
