The IMPACT (Informing the Pathway of Chronic Obstructive Pulmonary Disease Treatment) trial demonstrated a significant reduction in all-cause mortality (ACM) risk with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus UMEC/VI in patients with chronic obstructive pulmonary disease (COPD) at risk of future exacerbations. Five hundred seventy-four patients were censored in the original analysis owing to incomplete vital status information. Report ACM and impact of stepping down therapy, following collection of additional vital status data. Patients were randomized 2:2:1 to FF/UMEC/VI 100/62.5/25 μg, FF/VI 100/25 μg, or UMEC/VI 62.5/25 μg following a run-in on their COPD therapies. Time to ACM was prespecified. Additional vital status data collection and subsequent analyses were performed . We report vital status data for 99.6% of the intention-to-treat population ( = 10,355), documenting 98 (2.36%) deaths on FF/UMEC/VI, 109 (2.64%) on FF/VI, and 66 (3.19%) on UMEC/VI. For FF/UMEC/VI, the hazard ratio for death was 0.72 (95% confidence interval, 0.53-0.99; = 0.042) versus UMEC/VI and 0.89 (95% confidence interval, 0.67-1.16; = 0.387) versus FF/VI. Independent adjudication confirmed lower rates of cardiovascular and respiratory death and death associated with the patient's COPD. In this secondary analysis of an efficacy outcome from the IMPACT trial, once-daily single-inhaler FF/UMEC/VI triple therapy reduced the risk of ACM versus UMEC/VI in patients with symptomatic COPD and a history of exacerbations.
IMPACT(慢性阻塞性肺疾病治疗途径研究)试验表明,与乌美溴铵/维兰特罗(UMEC/VI)相比,糠酸氟替卡松/乌美溴铵/维兰特罗(FF/UMEC/VI)可显著降低慢性阻塞性肺疾病(COPD)患者的全因死亡率(ACM)风险,这些患者有发生未来加重的风险。由于不完全的生存状态信息,原始分析中有 574 名患者被删失。收集额外的生存状态数据后,报告 ACM 及降低治疗策略的影响。患者按照 2:2:1 的比例随机分配至 FF/UMEC/VI(100/62.5/25μg)、FF/VI(100/25μg)或 UMEC/VI(62.5/25μg)组,在接受 COPD 治疗的基础上进行了一次洗脱期。ACM 时间是预先指定的。进行了额外的生存状态数据收集和随后的分析。我们报告了意向治疗人群( = 10,355)的 99.6%的生存状态数据,记录了在 FF/UMEC/VI 组有 98(2.36%)例死亡、FF/VI 组有 109(2.64%)例死亡和 UMEC/VI 组有 66(3.19%)例死亡。对于 FF/UMEC/VI,死亡风险的 HR 为 0.72(95%置信区间,0.53-0.99; = 0.042),与 UMEC/VI 相比,与 FF/VI 相比为 0.89(95%置信区间,0.67-1.16; = 0.387)。独立的判断证实,心血管和呼吸道死亡以及与患者 COPD 相关的死亡发生率较低。在 IMPACT 试验疗效结果的二次分析中,每日一次的单吸入器 FF/UMEC/VI 三联疗法降低了有症状的 COPD 病史和加重史的患者的 ACM 风险。
