ABSTRACT

Objective: To assess the cost-effectiveness of atezolizumab in combination with carboplatin plus nab-paclitaxel-based chemotherapy versus chemotherapy alone for first-line treatment of advanced non-squamous non-small cell lung cancer (NSCLC) from the Chinese healthcare system perspective.

Methods: A Markov model was developed based on the IMpower130 clinical trial. Drug costs and health state utility were obtained from the literature. Outcomes included life-years (LYs), quality-adjusted life-years (QALYs), lifetime costs, and incremental cost-effectiveness ratio (ICER). One-way and probabilistic sensitivity analyses were performed to evaluate the model uncertainty.

Results: When compared to chemotherapy alone, atezolizumab plus chemotherapy provides an additional 0.34 LY and 0.19 QALY, and has an ICER of $180,560.15 per additional LY gained and that of $325,328.71 per QALY gained. Sensitivity analysis revealed that the results were most sensitive to changes in atezolizumab cost. Probabilistic sensitivity analysis showed that there was a 0% probability that atezolizumab plus chemotherapy was cost-effective at willingness-to-pay values of $30,828 per QALY. If the WTP threshold increased to $325,000 per QALY, atezolizumab plus chemotherapy has a 50% chance to be cost-effective.

Conclusions: From the Chinese healthcare system perspective, atezolizumab combination is not cost-effective for first-line therapy of advanced non-squamous NSCLC.
