●来自4万5千名非瓣膜性患者参加的真实世界研究结果证实拜瑞妥的出血率低

●ROCKETAF试验的扩展试验XANTUS结果表明拜瑞妥在高和低风险患者中都提供高效卒中预防效果

●正在进行的上市后安全性监测试验两年结果表明主要出血事件的发生率和发生形式与ROCKETAF试验一致

两个真实世界研究结果,分别是XANTUS试验和一项上市后安全性监测研究(PMSS),两个试验都表明Xa因子抑制剂拜瑞妥(利伐沙班)在用于房颤患者卒中预防的常规临床实践中大出血事件发生率低,这与III期ROCKET AF临床试验结果一致。两个试验涵盖了来自欧洲、加拿大和美国的4万5千多名患者的数据,欧洲心脏病杂志同意发表XANTUS研究结果全文。

英国伦敦圣乔治大学心血管与细胞科学研究中心临床心脏病学教授,XANTUS试验的主要研究者A.John Camm教授说:"真实世界研究证据对医生日益重要,能够补充和扩展临床试验中得到的认识。XANTUS是一项真实世界研究,结果表明利伐沙班在比III期临床试验中纳入的更广泛患者群中,特别是尽管血栓低风险,但仍然有抗凝需求的患者中的安全性和有效性。XANTUS试验为临床医生处方利伐沙班再次提供保证,这是一种在高和低卒中风险房颤患者中都有效、通常耐受性良好的药物。"

XANTUS试验是第一个在房颤患者中进行的非维生素拮抗剂类口服抗凝药的国际、前瞻性、真实世界研究,再次肯定了拜瑞妥在房颤患者中的正向收益风险情况,这种情况最初是在III期ROCKET AF临床试验表现出来的,拜瑞妥与华法令有着相似的整体出血情况,而最令人害怕的出血事件,如脑出血和致命性出血的发生率却显着低于华法令,胃肠道出血显着增高。其中,ROCKET AF试验患者都有中或者高卒中风险,CHADS2评分3.5;而XANTUS试验则平均卒中风险较低,CHADS2评分为2.0。在ROCKET AF研究中,服用利伐沙班的患者主要出血发生率为3.6/100患者年;在XANTUS试验中,利伐沙班的患者主要出血发生率为2.1/100患者年。另外,来自一项有39052名患者参加的上市后安全性监测研究(PMSS研究)进一步证实了利伐沙班良好的安全性,主要出血发生率为2.9/100患者年。

拜耳医药保健执行委员会成员,首席医学官Michael Devoy博士说:"拜耳一直致力于支持医生和患者安全负责地使用利伐沙班。作为这一承诺的一部分,上述研究非常重要,真实世界中的研究发现能够在医生日常临床实践中面临各种类型房颤患者时,帮助他们更有根据地进行临床决策。"

XANTUS和PMSS试验是正在进行的利伐沙班扩展试验中的两个,目前共有27.5万名患者已经或者即将被纳入到利伐沙班已经或者正在进行的临床试验或真实世界研究当中。

真实世界研究与随机对照试验、单病例随机对照试验在临床治疗性研究中的关系比较

临床工作及其研究是十分复杂的过程。不同个体虽患同种疾病,但临床表现互有差异,且临床反应的变化也不尽相同。因此,无法获得同一干预措施下不同个体的相同治疗效果;加之有的治疗措施缺乏真实性和实用价值,从而使得疗效评价成为一个难题。近些年来,普遍采用试验性的研究结果作为证据指导临床实践活动,其中以随机对照试验(RCT)最为受到重视,但由于RCT属于药物面市前研究,对研究对象的选择、治疗措施的应用等均有

实证研究/真实世界研究的功效与局限

20世纪80年代以来,实证研究在中国的社会研究中逐步被本土研究者所广泛采用,尤其中国社会学界对实证研究给予了高度重视,从而为解决中国社会的相关问题起到了不可低估的作用。实证研究之所以能在社会科学的各个领域得到广泛使用,是由其本身固有的优势所决定。当然,任何一种研究也有其局限性,实证研究也不例外。在临床上,近年来流行的真实世界研究,包括登记数据库研究,都属于实证研究,与经典的随机对照研究不同,更接近
