Abstract

Background

Transthyretin amyloidosis with cardiomyopathy (ATTR-CM) progressively impairs patients’ (pts) functional capacity, health status, and quality of life (QOL). In HELIOS-B, vutrisiran reduced all-cause mortality and cardiovascular events compared with placebo (pcb) in pts with ATTR-CM and demonstrated significant benefit on multiple clinical measures of disease progression.

Objectives

Study aimed to establish the efficacy and safety of vutrisiran in a contemporary population of pts with ATTR-CM.

Methods

In HELIOS-B, 6-minute walk test (6MWT) and Kansas City Cardiomyopathy Questionnaire-Overall Summary (KCCQ-OS) score were secondary endpoints assessing functional capacity and health status/QOL. We present further details on the efficacy of vutrisiran on pts’ functional capacity, health status, and QOL.

Results

In the overall population at Month 30, the difference of LS-mean change from baseline (vutrisiran–pcb) was 26.46 m (95% CI 13.38,39.55; P < 0.001) for the 6MWT and 5.80 points (95% CI 2.40,9.20; P < 0.001) for the KCCQ-OS. Over 30 months, in the overall population, 64% and 47% of pts treated with vutrisiran and pcb, respectively (P < 0.05) [monotherapy population; 65% and 38% (P < 0.05)], had an increase or < 5-point decrease in KCCQ-OS. Consistent benefits with vutrisiran were observed for both 6MWT and KCCQ-OS in prespecified subgroups, subdomains and different cut-off values/clinical thresholds. Similar trends were observed in the baseline tafamidis subgroup.

Conclusion

Significantly more pts treated with vutrisiran maintained or improved functional capacity and health status/QOL compared with pcb, providing further evidence of the disease-modifying effect of vutrisiran treatment. Secondary endpoint analyses of the HELIOS-B study demonstrated that vutrisiran preserved functional capacity (6MWT) and health status (KCCQ-OS) compared with pcb in pts with ATTR-CM. Benefits observed with vutrisiran were consistent in pre-specified subgroups, subdomains and different cut-off values/clinical thresholds.

vtrisiran对转甲状腺蛋白淀粉样变合并心肌病患者功能能力、健康状况和生活质量的维持或改善：来自HELIOS-B研究的数据

甲状腺素转蛋白淀粉样变合并心肌病（atr - cm）会逐渐损害患者的功能、健康状况和生活质量（QOL）。在HELIOS-B试验中，与安慰剂（pcb）相比，vutrisiran降低了atr - cm患者的全因死亡率和心血管事件，并在疾病进展的多项临床指标上显示出显著的益处。目的：研究旨在确定乌曲西兰在当代atr - cm患者中的有效性和安全性。方法在HELIOS-B中，6分钟步行测试（6MWT）和堪萨斯城心肌病问卷-总体总结（KCCQ-OS）评分是评估功能能力和健康状况/生活质量的次要终点。我们进一步详细介绍了vutrisiran对患者功能能力、健康状况和生活质量的影响。结果在第30个月的总体人群中，ls -平均变化与基线的差异（vutrisiran-pcb）为26.46 m (95% CI 13.38,39.55；P & lt;0.001)和5.80点(95% CI 2.40,9.20；P & lt;0.001)的KCCQ-OS。30个月后，在总体人群中，分别有64%和47%的患者接受了乌曲西兰和多氯联苯治疗(P <；0.05)[单药人群；65%和38% (P <；0.05)]，增加了<；KCCQ-OS下降5个点。在预先指定的亚组、子域和不同的临界值/临床阈值中，观察到vutrisiran对6MWT和KCCQ-OS的一致益处。同样的趋势也出现在基线他法底亚组。结论与多氯联苯相比，氟曲西兰治疗的患者维持或改善的功能能力和健康状况/生活质量明显高于氟曲西兰治疗，进一步证明了氟曲西兰治疗的疾病改善作用。HELIOS-B研究的次要终点分析表明，与pcb相比，vutrisiran可保持atr - cm患者的功能容量（6MWT）和健康状态（KCCQ-OS）。在预先指定的亚组、子域和不同的临界值/临床阈值中，vutrisiran观察到的益处是一致的。
