CSCO 2014:徐瑞华:晚期mCRC患者标准治疗失败后的新选择值得期待

2014-09-19 贾春实 中国医学论坛报

CONCUR研究是靶向药物瑞格非尼在亚太区,针对转移性结直肠癌(mCRC)患者进行的一项III期研究。 2012年,在全球进行的有关瑞格非尼对经治的mCRC患者疗效的研究——CORRECT研究,发表在《柳叶刀》The Lancet杂志上,这项研究报告的结果显示,瑞格非尼是能够在经所有标准治疗方案治疗后出现进展的结直肠癌患者中,首个显示出生存获益的小分子激酶抑制剂。瑞格非尼在欧洲和美国已经被批准用

CONCUR研究是靶向药物瑞格非尼在亚太区,针对转移性结直肠癌(mCRC)患者进行的一项III期研究。

2012年,在全球进行的有关瑞格非尼对经治的mCRC患者疗效的研究——CORRECT研究,发表在《柳叶刀》The Lancet杂志上,这项研究报告的结果显示,瑞格非尼是能够在经所有标准治疗方案治疗后出现进展的结直肠癌患者中,首个显示出生存获益的小分子激酶抑制剂。瑞格非尼在欧洲和美国已经被批准用于mCRC的治疗。鉴于此,有关瑞格非尼在亚太区的研究——CONCUR研究被启动。

CONCUR研究纳入以中国为主的患者,同时纳入韩国、台湾等地的患者。虽然该研究属于小样本研究,但即便如此,研究结果也达到了统计学阳性,明显地改善了患者的生存期及无进展生存期,所取得的数据较西方患者更加显著;这也是第2个证明瑞戈非尼单药治疗能改善转移性结直肠癌患者人群生存期的随机III期研究。

在CONCUR研究中,相比于安慰剂组,瑞戈非尼组患者的总生存期显著延长,意味着死亡风险随之降低;瑞戈非尼组的中位总生存期为8.8个月,而安慰剂组的中位总生存期为6.3个月。

此外,瑞戈非尼同安慰剂相比,能显著延长患者的无进展生存期,意味着疾病进展或死亡风险的降低;瑞戈非尼组的中位无进展生存期为3.2个月,而安慰剂组为1.7个月。瑞戈非尼组的疾病控制率(DCR)高于安慰剂组(52%和7%)。这项研究结果确立了瑞格非尼在亚太区患者中,特别是中国患者中具有较好的疗效。

2014年7月4日,上海复旦大学附属肿瘤医院主任、CONCUR研究牵头人李进教授在第16届世界胃肠肿瘤大会上,发表了CONCUR研究的结果。相信如果该药以后能够在中国上市,将会为中国的晚期结直肠癌患者,在治疗失败后,带来了更多的治疗机会。

CHMP建议批准拜耳regorafenib用于转移性结直肠癌(mCRC)治疗

拜耳(Bayer)上周末宣布,药物regorafenib获得了欧盟委员会(EC)人用医药产品委员会(CHMP)的积极意见。CHMP建议批准将regorafenib用于既往治疗过或不适用于当前可用疗法(包括基于氟尿嘧啶的化疗,抗VEGF疗法、抗EGFR疗法)的转移性结直肠癌(mCRC)成人患者的治疗。预计EC将于2013年第三季度作出审查决定。 CHMP的积极意见,是基于关键性III期CORREC
