Abstract

Introduction

The purpose of this study was to estimate the cost-effectiveness of atezolizumab plus chemotherapy in patients with metastatic non-squamous non-small cell lung cancer (NSCLC) from the United States (US) payers’ perspective in the first-line treatment.

Methods

A mathematical Markov model was developed to estimate cost and effectiveness of atezolizumab combination therapy versus carboplatin plus nab-paclitaxel alone in the first-line therapy of metastatic non-squamous NSCLC from the data of IMpower130. Costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs) were analyzed, and model robustness was assessed by sensitivity analysis. Additional subgroup analyses were performed as well.

Results

Compared to chemotherapy, treatment with atezolizumab plus chemotherapy yields an increase of 0.16 QALYs with an increase in cost of $109,809.13, resulting in an ICER of $670,309.66 per QALY. The most influential factor in this model was the cost of atezolizumab. Probabilistic sensitivity analysis showed that there was 0% probability that atezolizumab plus chemotherapy was cost-effective at willingness-to-pay (WTP) values of $150,000 per QALY. The results of subgroup analyses showed that the ICER remained greater than $150,000/QALY across the all patient subgroups.

Conclusion

First-line treatment with atezolizumab in combination with carboplatin plus nab-paclitaxel is not a cost-effective option in patients with metastatic non-squamous NSCLC.
