First-Line Atezolizumab for Metastatic NSCLC with High PD-L1 Expression: A United States-Based Cost-Effectiveness Analysis
Introduction The IMpower110 trial evaluated the efficacy and safety of atezolizumab in previously untreated patients with metastatic non-small cell lung cancer (NSCLC). Due to the high cost of immunity inhibitors, it is necessary to evaluate their value based on their efficacy and cost. This study evaluated the cost-effectiveness of atezolizumab as the first-line treatment for NSCLC with high programmed cell death ligand 1 (PD-L1) expression from the US payer perspective. Methods A Markov model with three health states was developed to estimate the cost and outcome of atezolizumab versus platinum-based chemotherapy in patients with previously untreated metastatic NSCLC with high PD-L1 expression. Model outputs included the life-years (LYs), quality-adjusted LYs (QALYs), total cost, and incremental cost-effectiveness ratios (ICERs). One-way and probabilistic sensitivity analyses were performed for all parameters. Results Atezolizumab produced an additional 1.32 QALYs (2.08 LYs) compared with platinum-based chemotherapy. The accompanying incremental cost was US$224,590. The results of one-way sensitivity analysis found that the ICER was most sensitive to the HR of OS. The probabilistic sensitivity analysis showed that the probability of atezolizumab being cost-effective compared with platinum-based chemotherapy was 10.28% and 37.71% at the willing-to-pay (WTP) threshold of $100,000/QALY and $150,000/QALY, respectively. Conclusion Atezolizumab was estimated not to be cost-effective compared with platinum-based chemotherapy in the first-line treatment of patients with NSCLC with high PD-L1 expression..
