诺华ALK阳性肺癌药物Zykadia色瑞替尼获欧洲批准

2015-05-12 佚名 生物谷

近日,诺华针对间变性淋巴瘤激酶阳性(ALK+)转移性非小细胞肺癌(NSCLC)患者的治疗药物Zykadia获得了欧洲药品管理局的批准,而一年之前美国就已经批准了该药物。 欧洲药品管理局批准Zykadia (ceritinib)用于治疗间变性淋巴瘤激酶阳性(ALK+)转移性非小细胞肺癌(NSCLC),这类患者病情已经恶化或对辉瑞的Xalkori (crizotinib)不耐受。针对这部分患者,

近日,诺华针对间变性淋巴瘤激酶阳性(ALK+)转移性非小细胞肺癌(NSCLC)患者的治疗药物Zykadia获得了欧洲药品管理局的批准,而一年之前美国就已经批准了该药物。

欧洲药品管理局批准Zykadia (ceritinib)用于治疗间变性淋巴瘤激酶阳性(ALK+)转移性非小细胞肺癌(NSCLC),这类患者病情已经恶化或对辉瑞的Xalkori (crizotinib)不耐受。针对这部分患者,Zykadia (ceritinib)将成为首选治疗药物。

这项批准决定主要是基于两个全球性、多中心、非盲单组临床实验结果。第一个名为ASCEND-1的试验A结果显示,给药的患者整体反应率(肿瘤缩小)为56.4%。而试验B(ASCEND-2)的数据将会在即将到来的一个医学会议上公布。

每年全球共有160万患者被诊断出肺癌,其中非小细胞肺癌(NSCLC)占比85%-90%,而这之中2%-7%的病例是由ALK基因重排导致的,ALK基因能够与其他基因融合,表达一种异常的融合蛋白,促进癌细胞的形成和生长。

针对这类患者,Xalkori是目前的标准治疗方式,然而不是所有患者都对Xalkori治疗有反应,一些患者病情会继续发展,这就迫切需要新的治疗药物。

此前一项针对接受过Xalkori治疗的 163名间变性淋巴瘤激酶阳性(ALK+)转移性非小细胞肺癌(NSCLC)患者的临床试验结果表明,患者使用Zykadia后整体反应率达到了54.6%,中位生存期达到了7.4个月。基于该试验结果,Zykadia获得了美国的加速批准。

ELCC2015:肺癌研究热点精粹

免疫治疗        在抗程序性死亡分子1及其配体(PD-1/PD-L1和细胞毒性T淋巴细胞相关抗原4 (CTLA-4)等抗体出现后,癌症的免疫治疗领域有了突飞猛进的发展。不同于传统的靶向治疗方法,其治疗的标靶是患者自身的免疫系统而不是直接针对肿瘤,通过重新激活患者的免疫细胞来对抗肿瘤。这一理论从癌症免疫疗法的临床试验中得到了令人鼓舞的结

新型DNA血液测试技术检测肺癌患者的突变

近日,来自瑞士的科学家们表示,在肺癌患者机体血液中循环的癌症DNA可以为医生们提供重要的突变信息,来帮助医生在患者肿瘤组织不易靶向作用的情况下对癌症疗法进行优化;相关研究为有效利用癌症疗法来靶向作用特殊癌症的突变提供了新的思路。检测肿瘤自身的突变并不总是有可能,然而很多研究都表明,循环在患者机体血液中的肿瘤DNA或许可以提供一些重要的指示信息。这项研究中研究者旨在对比标准方法检测肿瘤和利用血液检测

延长他汀类药物使用 降低肺癌死亡风险

近日一项研究表明,肺癌病人在诊断前或诊断后服用他汀类药物可降低肺癌造成的死亡风险。 一名来自北爱尔兰的研究人员指出:这项研究为肺癌病人服用他汀类药物可降低肺癌造成的死亡风险提供了一些证据。但他同时也说道,两者之间但关系并不是特别显著,他汀类药物服用者可能在其他一些方面与未服用他汀类药物的病人存在不同,导致他们因肺癌造成的死亡率降低,但这一发现仍值得进一步的观察研究。 在该项研究

吸烟与肺癌的关系

丹麦流传着一种说法,一户人家屋檐上的鹳巢数量与这家人所生孩子的数量存在着相关性。婴儿是鹳鸟送来的古老传说是真的吗?当然不是。相关性跟因果关系不是一回事。鹳不会送来孩子,但大房子有更大的空间为孩子和鹳所用。这是一则人们喜闻乐见的统计趣闻,但如果你知道1965年在美国参议院一场听证会上它是如何被用到的,你就不会觉得那么有趣了。那位做听证发言的专家证人辩称,尽管吸烟或许跟肺癌相关,但两者之间不存在已

Cancer cell:华人科学家发现氧化还原与肺癌新关系

近日,来自中科院生化所和复旦大学的研究人员在国际学术期刊cancer cell在线发表了一项最新研究进展。   LKB1基因能够编码丝氨酸/苏氨酸蛋白激酶LKB1, 研究发现该激酶可以调节细胞能量代谢、抑制生长增殖和维持细胞极性, 而这些都是该基因抑制肿瘤的重要机制。虽然LKB1能够调节细胞生长和能量代谢,但在非小细胞肺癌中,LKB1失活如何协调肿瘤进展与代谢之间的关系仍未可知。
