ABSTRACT
Objective:
The CAMEL clinical trial (412 patients were randomly assigned to either camrelizumab plus chemotherapy (n = 205) or chemotherapy alone (n = 207)) demonstrated that camrelizumab plus chemotherapy (CC) improved the overall survival time (OS) and progression-free survival time (PFS) of patients with metastatic nonsquamous non-small cell lung cancer (non-sq NSCLC) without epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK) mutations (EGFRm and ALKm) vs. chemotherapy (C) alone. Our objective was to conduct a cost-effectiveness analysis of CC vs. C from a perspective of health - care system in China with a lifetime horizon to identify whether it will be cost-effective. Materials andMethods:
A partitioned survival model (PSM) was applied for patients with IIIB-IV non-sq NSCLC without EGFRm and ALKm. Transition parameters and proportions of three health states were derived from the CAMEL trial. The model was designed using a lifetime horizon, a 21-day cycle, and a 5% discount rate of costs and outcomes. It was deemed cost-effective in China if the incremental cost-effectiveness ratio (ICER) value is less than $32,457 per quality adjusted life-year (QALY). Deterministic and probabilistic sensitivity analyses were performed to verify the influence of parameter uncertainty on the results.Results:
In the base-case analysis, we found that the ICER of CC compared with C is $-7,382.72/QALY which meant that CC had lower costs and better outcomes. The results of the sensitivity analyses demonstrated that the result was robust for the ICERs never transcending the willingness-to-pay (WTP) threshold.Conclusion:
Camrelizumab plus chemotherapy is an obviously cost-effective therapeutic regime for patients of IIIB-IV non-sq NSCLC without EGFRm and ALKm in China at a $32,457 WTP threshold.
