OP11 Cost-Effectiveness Of Atezolizumab Plus Chemotherapy As A First-Line Treatment For Metastatic Non-Squamous Non-Small Cell Lung Cancer
IntroductionTreatment with atezolizumab plus standard chemotherapy can prolong the overall survival of patients with metastatic non-squamous non-small cell lung cancer (NSCLC). However, the economic value of this treatment regimen is unknown. This study aimed to estimate the cost effectiveness of atezolizumab plus chemotherapy in the first-line treatment of metastatic non-squamous NSCLC from a healthcare system perspective in China.MethodsA partitioned survival model consisting of three discrete health states was developed to estimate the cost and effectiveness of atezolizumab plus carboplatin or cisplatin plus pemetrexed (APP) versus carboplatin or cisplatin plus pemetrexed (PP) in the first-line treatment of metastatic non-squamous NSCLC over a 12-year lifetime horizon. Key clinical data were generated from the IMpower132 trial. Local direct medical and non-medical costs were used and health preference data were collected from patients with NSCLC in 13 tertiary hospitals across five provinces in China. Costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs) were measured. One-way and probabilistic sensitivity analyses were performed to assess the robustness of the model.ResultsCompared with the PP regimen, APP therapy yielded a gain of 0.21 QALYs at an increased cost of CNY145,602 (USD22,574), resulting in an ICER of CNY684,894 (USD106,185) per QALY gained. The ICER was significantly higher than three times the gross domestic product per capita for China in 2021 (USD37,663). One-way sensitivity analyses revealed that one of the most influential factors in this model was the cost of atezolizumab. Probabilistic sensitivity analysis showed that there was 14.7% probability that atezolizumab plus chemotherapy was cost effective at a willingness-to-pay value of CNY242,928 (USD37,663) per QALY gained.ConclusionsThe APP regimen could prolong survival and improve health benefits over standard chemotherapy in the first-line treatment of patients with metastatic non-squamous NSCLC, but it is unlikely to be a cost-effective treatment option in China.
期刊介绍:
International Journal of Technology Assessment in Health Care serves as a forum for the wide range of health policy makers and professionals interested in the economic, social, ethical, medical and public health implications of health technology. It covers the development, evaluation, diffusion and use of health technology, as well as its impact on the organization and management of health care systems and public health. In addition to general essays and research reports, regular columns on technology assessment reports and thematic sections are published.
