| Summary: | Summary: Background: Access to immune checkpoint inhibitors remains limited due to cost-effectiveness and affordability concerns. This study evaluates the financial impacts of expanding global access to PD1/PD-L1 inhibitors as first-line monotherapy for patients aged 40–74 years with advanced unresectable non-small cell lung cancer (NSCLC), with wildtype EGFR and ≥50% of tumour cells with PD-L1 expression. Methods: The potential usage and associated costs were assessed from 2024 to 2040 through repeated cross-sectional assessments. The base case assumed treatment rates in countries with access to PD1/PD-L1 inhibitors in 2023, while expanded-access scenarios projected coverage increases to 30% in low-income, 50% in lower-middle-income, 80% in upper-middle-income (UMICs), and 95% in high-income countries over 10 years. Findings: The model estimated that 200,000–250,000 individuals are treatment-eligible, with only about one-fifth receiving PD1/PD-L1 inhibitors in the base case. Expanding access would increase global treatment coverage to 75% by 2040, particularly in middle-income countries. The largest increases would be in UMICs (+100,700) and the Western Pacific region (+82,400). At an estimated per-patient lifetime cost of US$37,600–US$75,100, total costs could reach US$14,087 million with fixed dosing, or US$9080 million with weight-based dosing. PD-L1 testing costs would add <1% to the total. Interpretation: Expanding access to PD1/PD-L1 inhibitors for advanced NSCLC over 10 years demands significant funding, making equitable access in lower-income countries doubtful without a significant price reduction. Policymakers should negotiate lower prices to ensure cost-effectiveness and affordability, improve spending efficiency by optimised dosing and treatment duration, and enhance health system capacity, including ensuring appropriate use and introducing biosimilars.
