Venetoclax, in combination with azacitidine, decitabine, or low-dose cytarabine (LDAC), received confirmatory approval in 2020 by the US Food and Drug Administration for the treatment of newly diagnosed acute myeloid leukemia (AML) in patients aged 75 years or older or who are ineligible for intensive induction chemotherapy. The economic value associated with response to venetoclax combinations compared with other treatments for this patient population has not been comprehensively evaluated. To assess the cost per patient achieving remission with venetoclax combination therapies, compared with other therapies for newly diagnosed patients with AML who are ineligible for intensive induction chemotherapy, from a US third-party payer perspective. The analysis used treatment effect estimates (ie, complete remission [CR] + CR with incomplete blood count recovery [CRi]) from a network meta-analysis and annual cost estimates from a prior budget impact model. The model considered the total cost of care including the costs of drug and administration, adverse events, hospitalization, disease monitoring, blood transfusions, and subsequent AML management when patients discontinued active treatment. Costs per patient achieving CR + CRi associated with venetoclax + azacitidine, venetoclax + LDAC, azacitidine, decitabine, LDAC, and best supportive care (ie, treatment given with the intent to maximize quality of life without specific antileukemic intent, such as blood transfusion products and antibiotics) were calculated as the annual total cost of care per patient divided by the CR + CRi rate. All costs were adjusted to 2020 US dollars. Venetoclax combination therapies were estimated to have substantially lower costs per patient achieving CR + CRi (venetoclax + azacitidine: $473,960; venetoclax + LDAC: $428,071) than alternative treatments. Azacitidine was estimated to have the the highest cost per patient achieving CR + CRi ($1,197,438), followed by best supportive care ($869,849), LDAC ($689,101), and decitabine ($594,074). A pair-wise matrix of the difference between therapies estimated that both venetoclax + azacitidine and venetoclax + LDAC were associated with significantly lower costs per patient achieving CR + CRi than azacitidine (by $723,477 and $769,367, respectively) and LDAC (by $215,141 and $261,030; all < 0.05). From a US third-party payer perspective, venetoclax in combination with azacitidine or LDAC was estimated to be associated with a significantly lower cost per patient achieving CR + CRi than azacitidine or LDAC among newly diagnosed patients with AML ineligible for intensive chemotherapy.

Venetoclax 联合阿扎胞苷、地西他滨或低剂量阿糖胞苷(LDAC)于 2020 年获得美国食品和药物管理局批准,用于治疗 75 岁及以上或不适合强化诱导化疗的新诊断急性髓系白血病(AML)患者。尚未全面评估与其他治疗方案相比,venetoclax 联合方案在该患者人群中的反应所带来的经济价值。 本研究旨在从美国第三方支付者的角度,评估 venetoclax 联合治疗方案与不适合强化诱导化疗的新诊断 AML 患者的其他治疗方案相比,实现缓解的患者的成本效益。 该分析采用了网络荟萃分析的治疗效果估计值(即完全缓解[CR]+不完全血细胞计数恢复的 CR[CRi])和之前预算影响模型的年度成本估算值。该模型考虑了包括药物和管理、不良反应、住院、疾病监测、输血以及患者停止积极治疗时后续 AML 管理的总成本。计算与 venetoclax+阿扎胞苷、venetoclax+LDAC、阿扎胞苷、地西他滨、LDAC 和最佳支持治疗(即,旨在最大限度地提高生活质量而没有具体抗白血病意图的治疗,如输血产品和抗生素)相关的达到 CR+CRi 的患者的成本效益比,方法是将每位患者的年总成本除以 CR+CRi 率。所有成本均调整至 2020 年的美元。 与其他治疗方案相比,venetoclax 联合治疗方案达到 CR+CRi 的成本效益比显著降低(venetoclax+阿扎胞苷:473960 美元;venetoclax+LDAC:428071 美元)。阿扎胞苷达到 CR+CRi 的患者的成本效益比最高(1197438 美元),其次是最佳支持治疗(869849 美元)、LDAC(689101 美元)和地西他滨(594074 美元)。治疗方案之间差异的两两矩阵估计,venetoclax+阿扎胞苷和 venetoclax+LDAC 与阿扎胞苷(分别为 723477 美元和 769367 美元)和 LDAC(分别为 215141 美元和 261030 美元)相比,达到 CR+CRi 的患者的成本效益比显著降低(均<0.05)。 从美国第三方支付者的角度来看,venetoclax 联合阿扎胞苷或 LDAC 与阿扎胞苷或 LDAC 相比,在不适合强化化疗的新诊断 AML 患者中达到 CR+CRi 的成本效益比显著降低。 这项研究得到了 AbbVie 公司和基因泰克公司的支持。赞助商帮助设计了研究、解释数据和起草手稿。Bui 博士和 Kapustyan 博士是 AbbVie 的员工,拥有该公司的股权;Choi 博士在研究进行期间是 AbbVie 的员工,拥有该公司的股权。Ma 女士和 Montez 博士是基因泰克的员工,拥有该公司的股权。Song 博士和 Chai 博士、Yin 女士和 Betts 博士是 Analysis Group,Inc. 的员工,该公司因这项研究从 AbbVie 和基因泰克获得了资金。LeBlanc 博士报告了与 AbbVie、Agios/Servier、AstraZeneca、Amgen、Astellas、BlueNote、CareVive、BMS/Celgene、Daiichi-Sankyo、Flatiron、Genentech、GSK、Pfizer 和 Seattle Genetics 的咨询或顾问委员会的个人酬金;从 UpToDate 获得版税;担任 Agios/Servier、AbbVie 和 BMS/Celgene 的演讲者费用;以及与美国癌症协会、AstraZeneca、BMS、Jazz Pharmaceuticals 和 Seattle Genetics 的研究合同或赠款。
