- Abstract
Background: The role of immune-related adverse events (irAEs), as a surrogate predictor of the efficacy of checkpoint inhibitors, has not yet been described in the setting of first-line, single-agent pembrolizumab for patients with metastatic non-small-cell lung-cancer (NSCLC) with a programmed death-ligand 1 (PD-L1) expression of ≥ 50%., Patients and Methods: We previously conducted a multicenter retrospective analysis in patients with treatment-naive metastatic NSCLC and a PD-L1 expression of ≥ 50% receiving first-line pembrolizumab. Here, we report the results of the irAE analysis and the potential correlation between irAEs and clinical outcomes., Results: A total of 1010 patients were included in this analysis; after a 6-week landmark selection, 877 (86.8%) patients were included in the efficacy analysis. Any grade irAEs (P < .0001), grade 3/4 irAEs (P = .0025), leading to discontinuation irAEs (P = .0144), multiple-site and single-site irAEs (P < .0001), cutaneous irAEs (P = .0001), endocrine irAEs (P = .0227), pulmonary irAEs (P = .0479), and rheumatologic irAEs (P = .0018) were significantly related to a higher objective response rate. Any grade irAEs (P < .0001), single-site irAEs (P < .0001), multiple-site irAEs (P = .0005), cutaneous irAEs (P = .0042), endocrine irAEs (P < .0001), gastrointestinal irAEs (P = .0391), and rheumatologic irAEs (P = .0086) were significantly related to progression-free survival. Any grade irAEs (P < .0001), single-site irAEs (P < .0001), multiple-site irAEs (P = .0003), cutaneous irAEs (P = .0002), endocrine irAEs (P = .0001), and rheumatologic irAEs (P = .0214) were significantly related to overall survival., Conclusions: This study confirms the feasibility and the safety of first-line, single-agent pembrolizumab, in a large, real-world cohort of patients with NSCLC with PD-L1 expression ≥ 50%. The occurrence of irAEs may be a surrogate of clinical activity and improved outcomes in this setting., (Copyright © 2020 Elsevier Inc. All rights reserved.)
