FDA批准针对三阴性乳腺癌的免疫治疗方案

2019-03-17 佚名 汉鼎好医友

近日,FDA加速批准阿特珠单抗(Atezolizumab,商品名:Tecentriq)联合nab-紫杉醇(Abraxane),用于一线治疗无法切除的局部晚期或转移性PD-L1阳性三阴性乳腺癌。阿特珠单抗是FDA批准的第一个PD-L1抑制剂,也成为首个针对乳腺癌的免疫治疗方案。纽约西奈山乳腺癌专家艾米·铁斯登博士称,这是个“非常令人振奋的消息”。伦敦玛丽皇后大学的研究作者彼得·施密德博士此前也在一份

近日,FDA加速批准阿特珠单抗(Atezolizumab,商品名:Tecentriq)联合nab-紫杉醇(Abraxane),用于一线治疗无法切除的局部晚期或转移性PD-L1阳性三阴性乳腺癌

阿特珠单抗是FDA批准的第一个PD-L1抑制剂,也成为首个针对乳腺癌的免疫治疗方案。

纽约西奈山乳腺癌专家艾米·铁斯登博士称,这是个“非常令人振奋的消息”。伦敦玛丽皇后大学的研究作者彼得·施密德博士此前也在一份声明中表示:“这是免疫疗法首次在如此难治的乳腺癌中起作用,对乳腺癌患者来说是一个巨大的进步。”

阿特珠单抗是罗氏旗下基因泰克研发的一种针对PD-L1的单克隆抗体。PD-L1是PD-1的配体,因此,阿特珠单抗算是纳武利尤单抗(Opdivo)、帕博利珠单抗(Keytruda)等PD-1抑制剂的“姻亲”,其机理同样是阻断PD-L1/PD-1的相互作用(免疫逃逸),让免疫系统重新识别并杀死癌细胞。

此次批准基于一项名为IMpassion130的III期临床试验。IMpassion13纳入了来自41个国家的902名患者,其中369名患者为PD-L1阳性。研究的主要终点是PFS和OS。结果表明,在PD-L1阳性的患者中,中位PFS从5.0个月提高到7.5个月,中位OS从15.5个月提高到25.0个月,提高近10个月。

三阴性乳腺癌被称为最凶险的乳腺癌,约占乳腺癌的10%~20%。这类乳腺癌之所以难治,是由于缺乏乳腺癌治疗最常见的三个标记物:雌激素受体(ER)、孕激素受体(PR)和人类表皮生长因子受体(HER-2)。这意味着,它对常规的内分泌治疗及分子靶向治疗均无效。而化疗的效果也难以令人满意。研究人员一直在寻求新的有效治疗方案。

由于缺乏治疗靶点,以及组织学分级和侵袭性高,三阴性乳腺癌相较其他亚型乳腺癌预后差得多,且其多见于绝经前的年轻患者,故也被称为“红颜杀手”。2013年,青年歌手姚贝娜正是因它英年早逝。

“阿特朱单抗联合nab-紫杉醇显着提高了PD-L1阳性转移性三阴性乳腺癌患者的治疗水平,对于该类乳腺癌患者具有重大意义。这将改变三阴性乳腺癌的治疗方式。”基因泰克首席医疗官桑德拉·霍宁说。

阿特朱单抗的获批史(2016年5.18首次批准)


不过,阿特朱单抗目前尚未在国内上市,并且价格不菲,每月的费用约为13400美元。我们期待它尽快进入国内,造福更多国内三阴性乳腺癌患者。
