Cost-effectiveness of camrelizumab plus chemotherapy in advanced squamous non-small-cell lung cancer

Objectives: A cost-effectiveness study of camrelizumab plus chemotherapy for advanced squamous non-small-cell lung cancer in China was conducted versus chemotherapy alone. Methods: Survival data were derived from CameL-Sq. Cost-effectiveness is indicated by an incremental cost-effectiveness ratio (ICER) less than the willingness-to-pay threshold. The partitioned survival model stability was assessed by sensitivity analyses. Results: With camrelizumab plus chemotherapy, quality-adjusted life years increased by 0.83, and cost increased by $21,259/patient versus chemotherapy. The ICER was $25,674/quality-adjusted life year. The probability of cost-effectiveness was >90% regardless of PD-L1 expression level. Regardless of the variation in each parameter across a wide range, the ICER never transcended the willingness to pay. Conclusion: Camrelizumab plus chemotherapy is a cost-effective first-line treatment for advanced squamous non-small cell lung cancer in China.
