摘 要 目的:评价泛基因型直接抗病毒药物(DAAs)治疗慢性丙型肝炎患者的成本-效用,为相关医疗卫生决策提供药物经济学
证据。方法:从全社会角度出发,以中国初治慢性丙型肝炎患者为目标人群,参考文献资料建立Markov模型,以索磷布韦维帕他
韦为对照,分析格卡瑞韦派伦他韦、索磷布韦+可洛派韦治疗慢性丙型肝炎患者的质量调整生命年(QALYs)和增量成本-效用比
(ICERs);采用敏感性分析验证结果的稳健性。结果:与索磷布韦维帕他韦相比,格卡瑞韦哌仑他韦增加了0.002 1 QALYs,成本增
加25 021元,ICERs为12 129 031元/QALY(意愿支付阈值为70 892元/QALY),不具有成本-效用;当其单价下降至1 679元时(降
价64.65%)将具有成本-效用。索磷布韦+可洛派韦增加了0.002 0 QALYs,成本减少515元,是成本节约的绝对优势方案。敏感性
分析显示,持续病毒学应答率和药品价格对结果的影响最大,索磷布韦+可洛派韦具有成本-效用的概率高于格卡瑞韦哌仑他韦。
结论:格卡瑞韦哌仑他韦需大幅降低价格,才可达到更好的可负担性;索磷布韦+可洛派韦具有良好的经济性。

ABSTRACT OBJECTIVE:To evaluate the cost-utility of the pan-genotypic direct-acting antivirals(DAAs)in the treatment of
patients with chronic hepatitis C infection, and to provide pharmacoeconomic evidence for relevant health care decisions.
METHODS:A Markov model was established from a societal perspective with newly diagnosed chronic hepatitis C patients in
China as the target population,and analyzed quality-adjusted life years(QALYs)and incremental cost-utility ratios(ICERs)of
patients with chronic hepatitis C with sofosbuvir/velpatasvir,glecaprevir/pibrentasvir,sofosbuvir+coblopasvir. Sensitivity analysis
was used to verity the robustness of the results. RESULTS:Glecaprevir/pibrentasvir increased QALYs by 0.002 1 and costs by 25 021
RMB,compared to sofosbuvir/velpatasvir;its ICERs was 12 129 031 yuan/QALY(willingness to pay threshold was 70 892
yuan/QALY),which had no cost-utility;glecaprevir/pibrentasvir need to cut down the price by 64.65% to have cost-utility.
Sofosbuvir + coblopasvir increased QALYs by 0.002 0 and saved costs by 515 yuan,so it was the optimal regimen which was
cost-saving. Sensitivity analysis showed that SVR rates and drug prices were the most influential factors. The probability of having
cost-utility for sofosbuvir+coblopasvir was higher than glecaprevir/pibrentasvir. CONCLUSIONS:Glecaprevir/pibrentasvir need to
reduce the price to achieve better affordability. Sofosbuvir+coblopasvir shows economical advantage.
