导读:2014年是礼来最为艰难的一年,数个畅销药遭仿制药重创。而肿瘤学管线中抗癌药Cyramza在今年的表现堪称完美,截至目前已收获FDA 3个批文,并于近日收获欧盟首个批文。业界预测,Cyramza的年销售峰值将突破15亿美元,该药在美欧市场的持续走强,将帮助缓解仿制药冲击导致的销售损失。

礼来(Eli Lilly)近日宣布,欧盟委员会(EC)已批准单抗药物Cyramza(ramucirumab):(1)联合紫杉醇(paclitaxel),用于既往经化疗治疗的晚期胃癌或胃食管交界腺癌(GEJA)成人患者的治疗;(2)作为一种单药疗法,用于不适合紫杉醇联合疗法的晚期胃癌或胃食管交界腺癌(GEJA)成人患者的治疗。

Cyramza是欧盟批准的首个胃癌二线治疗药物,标志着欧盟胃癌患者临床治疗的一个重大里程碑。胃癌也是Cyramza在欧盟获批的首个适应症,该药的获批,是基于2项大型III期研究(RAINBOW和REGARD)的数据,研究中Cyramza作为单药疗法或联合紫杉醇的组合疗法均显著改善了总生存期(OS)和无进展生存期(PFS)。此前,欧洲药品管理局(EMA)孤儿药产品委员会(COMP)已授予Cyramza治疗胃癌的孤儿药地位。

在美国,截至目前Cyramza已收获FDA 3个批文。本月中旬,FDA已批准Cyramza联合多西他赛(docetaxel,一种化疗药物)用于既往经含铂化疗治疗失败的转移性非小细胞肺癌(NSCLC)患者的治疗。此前,FDA已于今年4月和11月批准Cyramza及Cyramza+紫杉醇化疗联合疗法,用于晚期或转移性胃癌和胃食管交界腺癌(GEJA)的治疗。另外,礼来已计划于2015年上半年向FDA提交Cyramza+紫杉醇联合疗法治疗结直肠癌的上市申请,在III期临床中,该组合疗法显著改善了总生存期(OS)。

Cyramza是一种血管生成抑制剂,能够阻断肿瘤的血液供应,该药被认为是礼来研发管线中最重要的产品之一。不过,Cyramza的临床项目并不都是一帆风顺,去年秋天,Cyramza在乳腺癌III期临床中以失败告终,未能改善无进展生存期(PFS)。

关于Cyramza(ramucirumab)

ramucirumab是一种全人源化IgG1单克隆抗体,是一种受体拮抗剂,靶向结合于血管内皮生长因子(VEGF)受体2的胞外域,从而阻断血管内皮生长因子配体(VEGF-A,-C,-D)的相互作用,并抑制受体激活。

Ramucirumab由礼来于2008年耗资65亿美元收购ImClone公司后获得,目前正在开展相关临床试验,评估该药作为单药疗法及与其他抗癌药物的联合疗法,用于治疗乳腺癌、胃癌、非小细胞肺癌、大肠癌、肝癌、膀胱癌、尿道癌、输尿管癌、肾盂癌、前列腺癌、卵巢癌、多形性成胶质细胞瘤。目前乳腺癌、大肠癌、胃癌、肝癌、肺癌均处于III期临床开发。

J Cancer Res Clin:胆汁酸诱导MUC2表达可抑制胃癌肿瘤侵袭

胆汁酸可诱导粘蛋白(Mucin)表达,调节食管和结肠肿瘤行为。然而,胆汁酸对胃癌(GC)肿瘤侵袭性的影响目前还知之甚少。近日,韩国成均馆大学医学院和首尔国立大学医学院等处的学者就胆汁酸调节胃癌肿瘤侵袭的机制进行了研究,发现脱氧胆酸(DCA)可诱导胃癌细胞粘蛋白2(MUC2)表达,抑制肿瘤侵袭和转移,最新研究成果在线发表于12月5日的J Cancer Res Clin杂志上。

J Cancer Ther:忙工作也要注意身体 年轻人变胃癌主要患者

过去几十年里,全球胃癌(GC)发生率逐渐降低,然而,它仍在最容易发病的癌症中排名第五,在导致死亡的癌症中排名第三。不同区域的GC发病率存在较大差异,在东亚胃癌的发病尤为普遍。 尽管GC被认为是一种老年(50-60岁)疾病,但近年来,年轻人患胃癌的人数基本稳定,甚至还有少量增加。在中国西北部宁夏地区,年轻人患胃癌的临床病理特征还不够明晰。为了探究这一问题,宁夏医科大学内科肿瘤学学者调查了解11

吃夜宵导致胃癌?没有证据支持

流言:总是太晚进食,会增加患胃癌的风险。吃夜宵对胃的伤害非常大,因为胃黏膜上皮细胞的寿命很短,约2~3天就要再生一次,再生过程一般是在夜间胃肠道休息时进行。经常在夜间进餐会使胃黏膜得不到及时修复,甚至破坏胃黏膜。真相:夜晚太晚进食往往被认为会“伤胃”、“使胃得不到休息”,甚至还被认为是胃癌发生的罪魁祸首。在新闻报道中,“年轻白领常年加班吃夜宵患胃癌”这样的标题也不时出现。然而,即使在一些个例中

J Gastroenterol:预防胃癌 根除HP越早越好

幽门螺旋杆菌(HP)是胃癌的致病菌,根除HP的防癌作用近年来一直被关注。来自日本福渡市立医院的Take教授等在J Gastroenterol报道了他们团队的最新研究成果。 该团队过去曾做过相关研究,发现消化性溃疡患者通过HP根除治疗能够降低约1/3的胃癌发病风险(随访期平均3.4年)。本次研究仍然观察当初那个队列的受试群体,但随访期更长(平均9.9年)。 1222名消化性溃疡患者在

Lancet Oncology:Ramucirumab+紫杉醇治疗进展期胃癌疗效显著(RAINBOW Ⅲ期试验)

背景: VEGFR-2在胃癌发病机制及进展过程中发挥重要作用。Ramucirumab是一种抗VEGFR2单克隆抗体,本次研究试验目的是评价Ramucirumab联合紫杉醇对比安慰剂联合紫杉醇二线治疗进展期胃癌的疗效。 研究方法: RAINBOW研究为全球多中心随机双盲对照3期临床试验。入选标准:18岁及以上的进展期胃或胃食管结合部腺癌患者,一线氟尿嘧啶类+铂类药物治疗4个月内进展

Gut:HNF4α可能成为早期胃癌新的治疗靶点

韩国国立癌症中心和美国德克萨斯大学MD安德森癌症中心等处的研究者对胃癌的致瘤机制进行了进一步的研究,发现肝细胞核因子HNF4α为胃癌的一个通道癌蛋白,AMPKα-HNF4α-WNT5A信号轴可作为药物研发潜在的新的靶向通路,相关研究成果在线发表于近日的Gut杂志上。
