Abstract

Background: Pembrolizumab monotherapy and nivolumab in combination with ipilimumab are US FDA-approved first-line (1L) regimens for patients with metastatic non-small cell lung cancer (NSCLC) without epidermal growth factor receptor or anaplastic lymphoma kinase genomic aberrations and with a programmed death ligand 1 (PD-L1) tumor proportion score (TPS) of ≥ 1%. A published matching-adjusted indirect comparison found the two regimens yield comparable overall and progression-free survival outcomes. Objective: The aim of this study was to compare direct medical costs of pembrolizumab and nivolumab plus ipilimumab for PD-L1-positive metastatic NSCLC treatment within the first 3 years following treatment initiation from a US payer perspective. Methods: A cost-minimization model was built to estimate and compare treatment, disease management, and adverse event costs based on KEYNOTE-024 and -042, and CheckMate 227 Part 1a trial survival and adverse event data. Results: 1L pembrolizumab generates $54,343, $75,744, and $76,259 per patient cost savings compared with 1L nivolumab plus ipilimumab for patients with NSCLC with PD-L1 TPS ≥ 1% within 1, 2, and 3 years of treatment initiation, respectively. Conclusion: Pembrolizumab is cost saving as 1L treatment for PD-L1-positive metastatic NSCLC in comparison with nivolumab plus ipilimumab, at least for the short term.
