2017年3月21日讯 /生物谷BIOON /——一项评估阿斯利康PARP抑制剂奥拉帕尼(Lynparza)作为卵巢癌维持疗法的3期临床试验表明与安慰剂相比,该药物可以显著延长病人生存期。这项试验表明该药物可以显著延长携带生殖系BRCA突变(gBRCA)、复发且对铂类药物的化疗无反应的卵巢癌病人的无进展生存期(PFS)。试验期间采用300 mg的奥拉帕尼药片进行治疗,一日服用两次。这项随机


2017年3月21日讯 /生物谷BIOON /——一项评估阿斯利康PARP抑制剂奥拉帕尼(Lynparza)作为卵巢癌维持疗法的3期临床试验表明与安慰剂相比,该药物可以显著延长病人生存期。

这项试验表明该药物可以显著延长携带生殖系BRCA突变(gBRCA)、复发且对铂类药物的化疗无反应的卵巢癌病人的无进展生存期(PFS)。

试验期间采用300 mg的奥拉帕尼药片进行治疗,一日服用两次。这项随机、双盲、多中心的叫做SOLO-2的3期临床试验将口服聚ADP核糖聚合酶抑制剂作为单一维持疗法与安慰剂进行了对比。

阿斯利康首席医疗官和全球药物开发执行副总裁Sean Bohen说这项3期临床试验表明奥拉帕尼作为单一维持疗法可以使复发卵巢癌患者获益。

他说道:“这种药片能够降低病人服用的药物剂量,同时提供了与此前的临床试验相当的安全性能。我们将与监管机构一起协作使奥拉帕尼药片尽快进入市场。”

阿斯利康宣称奥拉帕尼将疾病进展的风险降低了70%,同时将PFS延长至19.1个月,而安慰剂组的PFS为5.5个月。

公司还称独立的盲审机构甚至宣称观察到PFS为30.2个月,而安慰剂组仍然为5.5个月。

这项3期SOLO-2试验还发现与安慰剂组病人相比,服用奥拉帕尼的病人二次进展或者死亡(PFS2)的时间具有统计学意义的显著性获益,同时其他重要的次要终点也有所改善。

阿斯利康补充说和此前试验相同的是奥拉帕尼药片具有安全性。根据阿斯利康的说法,奥拉帕尼治疗的病人血液学毒性发生率较低。

奥拉帕尼的机理是利用肿瘤DNA损伤反应通路缺陷选择性杀伤肿瘤细胞。这个药物已经在美国和欧洲获得批准治疗BRCAm的卵巢癌患者。(生物谷Bioon.com)
