NEJM:阿哌沙班在治疗癌症相关VTE方面不逊于达肝素(Caravaggio研究)

根据3月29日在美国ACC.20 / WCC会议最新临床研究结果分会场发布的Caravaggio试验结果,对于癌症相关复发性静脉血栓(VTE)的治疗,口服阿哌沙班的效果不劣于皮下注射达肝素(dalteparin),该试验同时发表于《新英格兰医学杂志》。

最近的指南建议考虑使用口服依托沙班或利伐沙班治疗癌症患者的静脉血栓栓栓塞症。然而,由于使用这些口服药物会增加出血的风险,因此这些口服药物的疗效有限。

Giancarlo Agnelli博士等人试图在这项带有盲法设计的开放性试验中评估口服阿哌沙班是否不劣于皮下达肝素,以预防癌症患者复发性VTE而不会增加大出血的风险。最近的指南建议在癌症患者中考虑使用其他口服抗凝剂治疗VTE,但由于使用它们会增加出血风险,因此其益处有限。

有症状或偶发的急性近端深静脉血栓形成或肺栓塞患者,被随机分配接受口服阿哌沙班(第一周每日2次10mg,第二周开始每日2次5mg)或皮下达肝素(第1个月按体重200 IU / kg,每日1次;第2个月按体重150 IU / kg,每日1次)。治疗持续了6个月。主要结果是客观确诊的复发VTE,大出血是主要安全结果。

研究结果表明,阿哌沙班组576例患者中有32例(5.6%)发生复发性VTE,达肝素组579例患者中有46例(7.9%)发生了复发性VTE(危险比,0.63;95%置信区间[CI] ],0.37-1.07;非劣效性p <0.001)。阿哌沙班组的22例患者(3.8%)和达肝素组的23例(4.0%)发生了大出血(危险比,0.82; 95%CI,0.40-1.69; p = 0.60)。

阿哌沙班与达特帕林组相比,其危险比为0.82,95%CI为0.40,1.69;P = 0.60。口服阿哌沙班治疗癌症相关的静脉血栓栓栓塞症的效果不比皮下注射地尔泰帕林差。

Agnes Y. Y. Lee博士在评论中指出:“ Caravaggio试验和既往研究的证据令人信服地证明了apixaban作为治疗[VTE]癌症患者的另一种抗凝药物。但是鉴于现有试验的异质性,由于没有进行头对头的比较,现在还无法得出结论认为一种直接口服抗凝药比另一种口服抗凝药要好。在选择抗凝剂时,“ [临床医师]需要依靠详细的临床病史,确定癌症的类型、状况和治疗方法、以及出血风险、伴随用药等。”
