Background Tenofovir alafenamide-emtricitabine (F/TAF) was recently approved as a noninferior and potentially safer option than tenofovir disoproxil fumarate-emtricitabine (F/TDF) for HIV preexposure prophylaxis (PrEP) in the United States. Objective To estimate the greatest possible clinical benefits and economic savings attributable to the improved safety profile of F/TAF and the maximum price payers should be willing to pay for F/TAF over generic F/TDF. Design Cost-effectiveness analysis. Data Sources Published literature on F/TDF safety (in persons with and those without HIV) and the cost and quality-of-life effects of fractures and end-stage renal disease (ESRD). Target Population Age-stratified U.S. men who have sex with men (MSM) using PrEP. Time Horizon Five years. Perspective Health care sector. Intervention Preexposure prophylaxis with F/TAF versus F/TDF. Outcome Measures Fractures averted, cases of ESRD averted, quality-adjusted life-years (QALYs) saved, costs, incremental cost-effectiveness ratios (ICERs), and maximum justifiable price for F/TAF compared with generic F/TDF. Results of Base-Case Analysis Over a 5-year horizon, compared with F/TDF, F/TAF averted 2101 fractures and 25 cases of ESRD for the 123 610 MSM receiving PrEP, with an ICER of more than $7 million per QALY. At a 50% discount for generic F/TDF ($8300 per year) and a societal willingness to pay up to $100 000 per QALY, the maximum fair price for F/TAF was $8670 per year. Results of Sensitivity Analysis Among persons older than 55 years, the ICER for F/TAF remained more than $3 million per QALY and the maximum permissible fair price for F/TAF was $8970 per year. Results were robust to alternative time horizons and PrEP-using population sizes. Limitation Intermittent use and on-demand PrEP were not considered. Conclusion In the presence of a generic F/TDF alternative, the improved safety of F/TAF is worth no more than an additional $370 per person per year.

品牌替诺福韦艾拉酚胺-恩曲他滨相对于仿制药替诺福韦二吡呋酯富马酸盐-恩曲他滨用于 HIV 暴露前预防的定价比较:成本效益分析。



背景 在美国,替诺福韦艾拉酚胺-恩曲他滨 (F/TAF) 最近被批准作为一种不劣于富马酸替诺福韦二吡呋酯-恩曲他滨 (F/TDF) 的潜在更安全的选择,用于 HIV 暴露前预防 (PrEP)。目的 评估 F/TAF 安全性改善带来的最大可能临床效益和经济节省,以及支付者愿意为 F/TAF 相对于仿制药 F/TDF 支付的最高价格。设计成本效益分析。数据来源 关于 F/TDF 安全性(感染和未感染 HIV 的人)以及骨折和终末期肾病 (ESRD) 的成本和生活质量影响的已发表文献。目标人群 使用 PrEP 的按年龄分层的美国男男性行为者 (MSM)。时间范围 五年。观点 医疗保健行业。干预 使用 F/TAF 与 F/TDF 进行暴露前预防。结果衡量指标 与通用 F/TDF 相比,F/TAF 避免骨折、避免 ESRD 病例、节省质量调整生命年 (QALY)、成本、增量成本效益比 (ICER) 以及 F/TAF 的最高合理价格。基本案例分析结果 在 5 年范围内,与 F/TDF 相比,F/TAF 为 123 610 名接受 PrEP 的 MSM 避免了 2101 例骨折和 25 例 ESRD,每个 QALY 的 ICER 超过 700 万美元。如果通用 F/TDF 有 50% 的折扣(每年 8300 美元),并且社会愿意为每个 QALY 支付高达 100 000 美元,则 F/TAF 的最高公平价格为每年 8670 美元。敏感性分析结果 在 55 岁以上的人群中,F/TAF 的 ICER 仍高于每 QALY 300 万美元,F/TAF 的最大允许公平价格为每年 8970 美元。结果对于替代时间范围和 PrEP 使用人群规模而言是稳健的。 限制 未考虑间歇性使用和按需 PrEP。结论 在存在通用 F/TDF 替代品的情况下,F/TAF 安全性的提高所带来的价值不超过每人每年额外增加 370 美元。主要资金来源国家过敏和传染病研究所、国家药物滥用研究所、国家心理健康研究所和马萨诸塞州总医院研究执行委员会。
