Lancent Respiratory Medcine:itepekimab治疗中重度慢阻肺患者可能有效

2021-08-03 MedSci原创 MedSci原创

当前治疗慢性阻塞性肺疾病(COPD)的目标是控制症状、改善肺功能、减少急性加重,并降低死亡率。但现有的吸入性皮质类固醇和长效支气管扩张剂疗法对减少COPD急性加重和疾病进展的影响并不大。

当前治疗慢性阻塞性肺疾病COPD的目标是控制症状、改善肺功能、减少急性加重并降低死亡率。现有的吸入性皮质类固醇和长效支气管扩张剂疗法对减少COPD急性加重和疾病进展的影响不大,需要针对急性加重有效疗法。

近日,发表在《柳叶刀呼吸医学》的一项研究数据表明针对曾经吸烟的COPD患者itepekimab治疗可能是有益的

 

方法

该研究在10个国家的83个研究点进行了一项双盲2a期试验参与者年龄在40-75岁之间现在吸烟或曾经吸烟已被诊断患有慢性阻塞性肺病至少1年,正在接受三联疗法或二联疗法的维持治疗。参与者被1:1随机分配接受itepekimab300mg或安慰剂治疗,每2周皮下注射两次,持续24-52周。试验数据分析使用负二项式回归模型评估COPD中重度急性加重年发生率的治疗差异,使用混合效应模型来评估支气管扩张剂使用FEV1从基线到第16-24周的平均变化,Cox回归模型分析首次中重度急性加重事件发生时间等。

 

结果

从2018年7月16日至2020年2月19日,343名患者被随机分配到安慰剂组n=171或itepekimab组n=172安慰剂组COPD急性加重的年发生率为1.6195%CI1.32–1.97,itepekimab组为1.3095%CI1.05–1.61相对风险RR=0.81[95%CI:0.61–1.07],p=013)。

从基线到第16–24周支气管扩张最小二乘平均FEV1变化为0.0LSD=0.02和0.06L0.02;差值0.06L[95%CI0.01–0.10],p=0024次中重度急性加重事件发生时间的风险比HR为0.83(95%CI0.61-1.12p=0.22)

当分析仅限于曾经吸烟者时,与安慰剂相比,itepekimab治疗使COPD急性加重显著减少(RR=0.58,p=0.0061)和FEV1改善(最小二乘平均差0.09L,p=0.0076)。而对于现在吸烟者而言,接受itepekimab治疗减少急性加重和FEV1改善方面没有显示出治疗益处

mITT人群和相关亚组的疗效结果(mITT=改良治疗人群)

 

相对于基线的FEV1随时间的变化:mITT(A)、曾经吸烟者(C)、现在吸烟者(E)

首次中重度急性加重率随时间的变化:mITT(B)、曾经吸烟者(D)、现在吸烟者(F)

EOT=治疗结束访问,EOS=研究结束访问(EOT后20周)

 

结论

中重度慢阻肺患者,itepekimab治疗未实现降低其急性加重的年发生率,但降低了曾经吸烟者的疾病恶化率,并改善了肺功能。对于COPD患者,这是第一项证明生物疗法(itepekimab抑制IL-33可能有效)在降低恶化率和肺功能方面具有潜在益处的研究。另外,二项3期临床研究正在进行中,以更好地了解这种新型疗法的潜力,可能为曾经吸烟的COPD患者治疗提供安全有效的新疗法。
