乳腺癌新药3期临床疗效显著,已向FDA提交新药申请

2016-07-24 佚名 药明康德

今天,总部位于美国洛杉矶的生物技术公司 Puma Biotechnology 宣布了最新补充的积极3期临床试验(ExteNET trial)结果,在该项研究中使用其在研新药来那替尼(neratinib)延长性辅助治疗早期HER2阳性反应的乳腺癌患者。同时,基于这些良好的3期(ExteNET)结果,Puma 向美国FDA提交了一份有关来那替尼的新药申请(NDA)


今天,总部位于美国洛杉矶的生物技术公司 Puma Biotechnology 宣布了最新补充的积极3期临床试验(ExteNET trial)结果,在该项研究中使用其在研新药来那替尼(neratinib)延长性辅助治疗早期HER2阳性反应的乳腺癌患者。同时,基于这些良好的3期(ExteNET)结果,Puma 向美国FDA提交了一份有关来那替尼的新药申请(NDA),可用于延长性辅助治疗已经先前接受过曲妥珠单抗(trastuzumab) 辅助治疗的早期HER2过度表达的乳腺癌病人。

 

众所周知,乳腺癌是威胁全世界女性健康的第一恶性肿瘤,而HER2阳性乳腺癌更是其中最凶险的类型之一。HER2又名“人类表皮生长因子受体2”,乳腺癌HER2阳性其实意味着病人体内的表皮生长因子受体2过度表达,这种被激活的蛋白质可传递信号,刺激癌细胞疯狂增殖。相较于其它类型的乳腺癌,HER2阳性乳腺癌患者对内分泌治疗不敏感、进展速度更快、恶性程度更高,同时也更容易复发和转移,由于化疗效果不理想,预后情况也相对更差。HER2阳性的乳腺癌患者术后复发风险也远高于其他人群。  

 

据世界卫生组织统计,中国每年有16.9万患者被新确诊为乳腺癌,其中,20%~30%的人群罹患的便是HER2阳性乳腺癌。目前的治疗方案包括了使用曲妥单抗辅助治疗,它可导致HER2阳性早期乳腺癌患者复发率下降,但是临床上仍希望能尝试进一步降低疾病的复发风险,进而改善预后。

 

来那替尼是一种有效的不可逆的酪氨酸激酶抑制剂,阻止通过表皮生长因子受体,HER1,HER2和HER4信号通路转导。Puma Biotechnology 向美国FDA提交来那替尼的NDA是基于上述名为ExteNET的双盲、安慰剂对照、3期试验,结果表明应用来那替尼能够进一步改善这种疾病的患者预后。该ExteNET试验在41个国家随机招募了2840例早期HER2阳性乳腺癌患者。该研究的主要终点为无病生存期(DFS),结果表明,与安慰剂相比,来那替尼使无病生存期改善33%,具有统计学上的显著差异(HR = 0.67; P = 0.0046)。

 

Puma的总裁兼首席执行官Alan H. Auerbach 先生评论说道:“我们非常高兴地宣布这一重要的监管里程碑。我们致力于进一步降低HER2阳性乳腺癌患者的复发风险,相信来那替尼或许能够提进一步帮助这些患者。我们期待着在NDA提交的审查期间与FDA紧密合作。”

该公司认为,来那替尼在治疗其他几个癌症的临床应用也很有潜力,包括HER2过度表达或存在突变的非小细胞肺癌等其他类型肿瘤。

Breast Cancer Res:长期使用钙离子通道阻滞剂并不会增加乳腺癌的发病风险

近日,一项病例对照研究发现长期使用钙通道阻断药物与乳腺癌的发病风险增加两倍有关。若前瞻性研究证实钙离子通道阻断剂可增加乳腺癌的发病风险,那么这将大大影响高血压的治疗。本研究旨在通过与不使用钙通道阻滞剂的女性相比,确定使用钙离子通道阻滞剂治疗10年及以上的女性乳腺癌的发病风险是否会增加。研究纳入了35-74岁之间的女性,纳入标准要求参与者有一个乳腺癌的姐妹,但是参与者本身并没有诊断为乳腺癌。本研究共

Breast Cancer Res:辟谣!大型前瞻性研究发现女性心理压力并不会增加乳腺癌的发病风险

女性诊断为乳腺癌后通常将其病因归咎于心理压力,但是支持此看法的研究甚少。本研究旨在探究常有心理压力及不良生活事件是否会影响日后乳腺癌的发生风险。采用前瞻性研究共纳入了英国10.6万名女性,均匀随访6.1年,其间1783名女性发生乳腺癌。使用Cox比例风险模型评估相对风险来作为风险比。结果并未发现乳腺癌发病风险与心理压力的频率相关。随访前5年期间,近亲死亡的乳腺癌危险降低13%(RR:0.87,95
