FDA多数专家反对坎格雷洛用于减少PCI患者血栓性心血管事件

2014-02-13 晓静 编译 医学论坛网

美国食品与药物管理局(FDA)顾问小组以7:2的投票结果反对静脉用抗血小板药坎格雷洛(cangrelor)用于减少经皮冠状动脉介入治疗(PCI)患者的血栓性心血管事件。成员组的多数专家认为该药的风险/获益尚有争议。尤其是一些专家对于全部证据存在困惑,值得注意的是,虽然CHAMPION-PHOENIX研究结果是阳性的,但仍有两项关于坎格雷洛的临床试验结果是阴性的。 相关阅读:ESC 201

ESC 2013:CHAMPION研究分析显示坎格雷洛可降低PCI术时的血栓事件

ESC 2013会议上展示了CHAMPION试验的汇集分析结果,研究结果已发表在2013年9月3日的Lancet杂志上。以Gabriel Steg博士(法国巴黎Bichat医院)为首的研究团队称,这项研究的数据来自CHAMPION-PCI, CHAMPION-PLATFORM和CHAMPION-PHOENIX试验,因此代表“PCI术时坎格雷洛治疗临床结局的总体证据”。值得一提的是,FDA于2013年7月接受了制造商对坎格雷洛的新药申请。

PCI期间使用坎格雷洛可减少合并症发生(CHAMPION-PHOENIX研究)

CHAMPION-PHOENIX研究结果在线发表于新英格兰医学杂志,首席作者为Deepak L Bhatt博士(波士顿医疗保健体系和麻省Brigham妇女医院),这项研究的副主持人Bhatt博士曾在美国心脏病学会2013年会上报道过这一试验结果。

试验的主要结局在今年一月份面向投资者的医学会议上曾简要公布过,heartwire同时给予报道。Bhatt等人称,CHAMPION-PHOENIX研究是于CHAMPION PCI和CHAMPION PLATFORM这些早期3期试验之后开展的,然而,后两项试验的研究者并未发现与氯吡格雷相比,坎格雷洛在主要有效性终点方面的获益,只是显示对一些重要的次要终点有所改善,如支架内血栓形成,且未增加出血风险。

PCI期间使用坎格雷洛可减少合并症发生(CHAMPION-PHOENIX研究)

两种抗血小板ADP受体阻滞剂药物以两种给药方式——静脉注射与口服,均可用于冠状动脉疾病介入治疗,然而如何选择是一件艰苦的事情:一项纳入超过1100例患者的随机试验发现,与口服氯吡格雷治疗相比,静脉给予坎格雷洛可减少所有形式PCI围手术期并发症风险,而前者很长时间内都是用于此类手术的标准药物疗法。 这一新药可使预定义的复合有效性终点降低百分之22,包括MI和支架内血栓形成的减少,且不引起出血并发症

研究要点:1.CHAMPION汇集分析共包括三个关键的试验:CHAMPION-PCI、CHAMPION-PLATFORM和CHAMPION-PHOENIX试验。2.坎格雷洛与氯吡格雷或安慰剂相比可降低PCI术围手术期血栓并发症风险。但轻微出血事件发生增加。3.FDA在2013年7月接受坎格雷洛的新药申请。ESC2013会议上展示了CHAMPION试验的汇集分析结果,研究结果已发表在2013年9月3
