摘要

目的:Teclistamab和elranatamab是最近批准用于治疗三重暴露的复发/难治性多发性骨髓瘤(RRMM)的双特异性抗体。本研究利用MajesTEC-1 (NCT03145181/NCT04557098)和MagnetisMM-3 (NCT04649359)试验的数据,通过匹配调整间接比较(MAIC)和每应答者成本分析,评估了teclistamab和elranatamab的相对疗效和经济价值。材料和方法:MAIC在对来自MajesTEC-1的个体患者数据进行加权以匹配MagnetisMM-3的关键基线特征后,比较了两种疗法之间的总缓解率(ORR)。匹配的协变量包括年龄、难治性状态、既往治疗线、髓外疾病、表现状态、疾病分期和细胞遗传学风险概况。每个应答者的成本是根据6个月内每位患者估计的药物获取和管理成本(2024美元)除以ORR来计算的。进行了单向和概率敏感性分析来表征不确定性。结果:配对前的orr为63.0% (N = 165),配对后的orr为61.4%(有效样本量为92),elranatamab的orr为61.0%(配对后的优势比为1.02;95%可信区间[CI]: 0.59, 1.77)。teclistamab的每名患者成本估计为231,435美元,elranatamab为285,201美元(差异:- 53,766美元;95%置信区间[CI]: - 59,094美元,- 48,311美元),每个应答者的收益成本分别为376,930美元和467,730美元(差异:- 90,800美元;95% ci: - 183,680美元,8,148美元)。局限性:由于MajesTEC-1和MagnetisMM-3是单臂试验,MAIC没有锚定,因此容易受到任何未调整的效应调节剂或预后变量的干扰。结论:在三级暴露的RRMM中,Teclistamab与elranatamab相比显著降低治疗成本和每个应答者的数值成本。

Cost per responder for teclistamab and elranatamab in relapsed or refractory multiple myeloma in the United States.

Aims: Teclistamab and elranatamab are bispecific antibodies recently approved for the treatment of triple class-exposed relapsed/refractory multiple myeloma (RRMM). This study assessed the relative efficacy and economic value of teclistamab and elranatamab through a matching-adjusted indirect comparison (MAIC) and cost per responder analysis using data from the MajesTEC-1 (NCT03145181/NCT04557098) and MagnetisMM-3 (NCT04649359) trials.

Materials and methods: The MAIC compared overall response rate (ORR) between the therapies after weighting individual patient data from MajesTEC-1 to match key baseline characteristics in MagnetisMM-3. Matched covariates included age, refractory status, prior lines of therapy, extramedullary disease, performance status, disease stage, and cytogenetic risk profile. Cost per responder was calculated based on estimated per-patient drug acquisition and administration cost (2024 United States dollars) over 6 months divided by ORR. One-way and probabilistic sensitivity analyses were conducted to characterize uncertainty.

Results: The ORRs were 63.0% for teclistamab before matching (N = 165), 61.4% for teclistamab after matching (effective sample size = 92), and 61.0% for elranatamab (N = 123) (odds ratio after matching: 1.02; 95% confidence interval [CI]: 0.59, 1.77). Per-patient costs were estimated to be $231,435 for teclistamab and $285,201 for elranatamab (difference: -$53,766; 95% confidence interval [CI]: -$59,094, -$48,311), yielding costs per responder of $376,930 and $467,730, respectively (difference: --$90,800; 95% CI: -$183,680, $8,148).

Limitations: Because MajesTEC-1 and MagnetisMM-3 are single-arm trials, the MAIC was unanchored and therefore susceptible to confounding from any unadjusted effect modifiers or prognostic variables.

Conclusions: Teclistamab was associated with significantly lower treatment costs and numerically lower cost per responder than elranatamab in triple class-exposed RRMM.
