| アブストラクト | BACKGROUND: Immune checkpoint inhibitors (ICIs) and bevacizumab-based therapy are a promising treatment approach to significantly improving overall survival (OS) of non-small cell lung cancer (NSCLC) patients. However, the incidence of adverse events induced by a combination treatment with programmed cell death-1 or programmed death ligand 1 [PD-(L)1] inhibitor and bevacizumab remains unknown. The current evidence from prospective studies is limited. Thus, efforts using real-world data to further improve our understanding of the potential adverse events will be necessary. METHODS: The present study included 15,872 participants with NSCLC in the FDA Adverse Event Reporting System (FAERS) database from April 2013 to September 2019. The definition of adverse events (AEs) relied on the Medical Dictionary for Regulatory Activities (MedDRA). Statistical analysis was performed, and odds ratio (ORs) with 95% confidence intervals (CIs) were calculated. RESULTS: Of the 15,872 participants with NSCLC, 15,463 cases were treated with the PD-(L)1 inhibitor monotherapy, while 409 cases were treated with both PD-(L)1 inhibitor and bevacizumab. Compared with monotherapy, combination therapy had lower risks of pneumonitis, respiratory failure, edema, disease progression, and death; however, combination therapy was also associated with significantly higher risks of pyrexia, general physical health deterioration, stomatitis, dehydration, thrombocytopenia, peripheral neuropathy, nephritis, bone marrow failure, immune thrombocytopenic purpura, neutropenia, and serious AEs. The results of the multivariate analysis suggested that combination therapy was the independent risk factor for pyrexia, neutropenia, nephritis, ITP, and the independent protective factor for respiratory failure. CONCLUSIONS: We observed that the spectrum and risk of irAEs differed widely between therapeutic regimens, and irAEs involved multiple organ systems both in monotherapy or combination therapy. Deepening our understanding of irAEs has a great clinical value for improving individualized clinical patient management and the safety of medication use. |
