Combining Immune Checkpoint Inhibitors and Anti-Angiogenesis Approaches: Treatment of Advanced Non-Small Cell Lung Cancer.

Combining immune checkpoint inhibitors (ICIs) and anti-angiogenic pharmacologic agents is an encouraging therapeutic approach in the treatment of non-small cell lung cancer (NSCLC). Currently, the only FDA-approved therapy combining an immune checkpoint inhibitor and a vascular endothelial growth factor (VEGF) inhibitor is atezolizumab, bevacizumab, and chemotherapy in first-line metastatic NSCLC patients. However, the combination of nivolumab, a programmed death-1 (PD-1) inhibitor, and bevacizumab has also shown encouraging results in patients with NSCLC with minimal adverse effects, respectively. This communication aims to highlight the efficacy of nivolumab and bevacizumab in NSCLC patients without sensitizing mutations in epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), or ROS proto-oncogene 1 (ROS1). In addition, the combination of nivolumab/atezolizumab and bevacizumab with other therapeutic agents is also discussed. We also underscore the adverse effects and limitations of such combinations in NSCLC patients. Future studies should focus on large-scale trials and biomarker identification to establish the benefits of these combination therapies in NSCLC patients.
