ABSTRACT

Objective

The aim of the study was to evaluate the cost-effectiveness of adding atezolizumab to first-line chemotherapy for advanced nonsquamous non-small-cell lung cancer (NSCLC) from Chinese healthcare system.

Methods

A partitioned survival model (PSM) was established to simulate 3-week patients transition in a 20-year time horizon to estimate the health and economic outcomes of adding atezolizumab to first-line chemotherapy for advanced nonsquamous NSCLC. Costs and utility values were obtained from the local charges and published studies. Sensitivity analyses were conducted to confirm the robustness of the model results.

Results

Atezolizumab plus chemotherapy yielded additional 0.36 life years (LYs) and 0.23 quality-adjusted life-years (QALYs), and the marginal cost was $60,154.48, resulting in an ICER of atezolizumab plus chemotherapy versus chemotherapy was $267,264.85/QALY. One-way sensitivity analyses revealed that the cost of atezolizumab was the main driver of the model outcomes, and the probabilistic sensitivity analyses suggested that atezolizumab plus chemotherapy had 0% probability of being cost-effective first-line option at the willingness-to-pay (WTP) threshold of $37,652/QALY in China.

Conclusions

Atezolizumab plus chemotherapy could not be considered cost-effective compared with chemotherapy alone as the first-line strategy for patients with advanced nonsquamous NSCLC in China. And appropriately reduce the price of atezolizumab is necessary.
