ASCO 2015:肿瘤药物争夺战

2015-06-04 佚名 生物谷

伴随着美国临床肿瘤学会会议(ASCO)的召开,整个生物制药投资界的目光都聚焦于芝加哥。 风险资本家Bruce Booth用近5000份会议摘要做了一个简要的数据分析。Booth认为,“虽然不清楚今年有什么正面或负面的新闻,至少直到这周末结束,从会议摘要中做的简要数据分析可以看出,医药界的关注点非常集中”。 会议摘要中有90%出现了关键词“病人”、“癌症”,接近三分之二提到“治疗”或包含“

伴随着美国临床肿瘤学会会议ASCO)的召开,整个生物制药投资界的目光都聚焦于芝加哥。

风险资本家Bruce Booth用近5000份会议摘要做了一个简要的数据分析。Booth认为,“虽然不清楚今年有什么正面或负面的新闻,至少直到这周末结束,从会议摘要中做的简要数据分析可以看出,医药界的关注点非常集中”。

会议摘要中有90%出现了关键词“病人”、“癌症”,接近三分之二提到“治疗”或包含“临床”参考文献。“化疗”和相关疗法大概出现了三分之一,抗体占到接近10%。“之所以跟大家分享这些,是因为这些数据分析能帮助我调整对会议摘要关键词的迅速调研”,Booth说,“虽然不是科学术语,但也具有一定参考价值”。

数据总结如下所示,表格显示了会议摘要提到特定药物靶点的数目(在几十个统计的靶点中出现最多的一部分):

要点速览

要点1:ErbB家族–HER2,EGFR,HER3—仍旧持续受到肿瘤界的关注。尽管距离这些受体被发现已过去了30年,酪氨酸激酶受体仍在摘要提及前四名关键词中占据了三个位置。几十种针对这些靶点的抗癌药,再加上大家对不同肿瘤类别间基因表达模式的极大兴趣,文摘中出现次数这么多就不奇怪了。不过在整个排行榜中这么庞大的量还是让人吃惊。除了一些被批准的药物外,ErbB活性抑制剂(Puma,others),突变选择抑制剂(Clovis,AZ),以及其他ErbB相关产品的项目也在进行中。总之,在几十年后仍有这么多针对ErbB家族蛋白研究,而且显然还有更多针对ErbB家族蛋白的药物在研,这让人十分吃惊。

要点2:免疫肿瘤学的检验点靶标,PD-1和PD-L1有上百篇摘要报导,远远领先于其他免疫靶标。许多专注于肿瘤领域的公司都提交了关于PD-1的摘要,如默克(Merck),百时美施贵宝(BMS),阿斯利康(AZ)诺华(Novartis),罗氏(Roche)以及很多其他药企。其他T细胞相关靶点如CTLA-4, TIM-3,OX-40, 和LAG-3等也被频繁提及。提到人工改造的免疫细胞疗法(CAR-Ts)的摘要有几十篇。“与美国癌症研究协会(AACR)和美国血液肿瘤协会(ASH)相比,ASCO更关注于药物研发后期阶段,而且更偏向固体瘤方向。可能因为这些原因,这些新方法排在了PD-1和ErbB家族后面,这也是ASCO的特点。”Booth说。

“业界追逐相同的癌症靶标,只要临床数据验证了药物功能,激烈的竞争马上出现,就像ErbB和免疫肿瘤标记靶点,或者CAR-T领域的CD-19。每个靶点都有几十个临床前研究和临床阶段项目跟进。”

接下来将是erbB,免疫检验点和CD19 CAR-Ts之间在ASCO15会议上甚至在接下来的几年里你争我夺。尘埃落定后,生物医药企业以及它们的投资者们也会分出胜负。但是无论如何,这场战争中真正的赢家属于癌症患者,他们一定会因此受到更好的治疗。

ASCO 2015:ASCO现任主席对癌症治疗下一个50年的展望

主席寄语: 就在1年前,我们共同庆祝了美国临床肿瘤学会(ASCO">ASCO)的50周年纪念日,回顾了我们已经取得的杰出成就和里程碑似的飞跃。今天,站在ASCO历史上第2个50年的起点,我们要开始思考10年、20年乃至30年后,癌症和癌症的防治会发生哪些变化。我们要如何在日渐积累的、庞大而繁杂的知识库中找到真正的“宝藏”,让癌症患者最终获益?   ——彼得·保尔·于(Peter

ASCO 2015:孙燕院士点评肿瘤年度进展

思考--积累让我们更好地服务患者 我是从大跃进的年代开始从事临床肿瘤学工作的。当时有个豪迈的口号是“让高血压低头,让肿瘤让路”。坦白来讲,那时候我曾很幼稚地相信过在十年内我们有可能达到这些目标。但是后来在实践中体会到,肿瘤这类病因、发病机制和治疗都十分复杂的疾病,不可能通过一种简单的方法解决。 一位美国同行德维塔(VT DeVita)说,“由于肿瘤的复杂性,进展只能是渐进的。”那么,高血压有没

ASCO 2015:高危或者转移性前列腺癌ADT联合化疗显生存优势(STAMPEDE研究)

对新诊断未接受内分泌治疗的进展期前列腺癌患者,在标准雄激素剥夺治疗(ADT)的基础上加用多西他赛能显著改善该部分患者的总生存(OS)——根据2015 ASCO">ASCO年会新闻发布会上的STAMPEDE研究报道。 STAMPEDE研究共入组约7000例患者、9个亚组,是目前第2大前列腺癌临床研究。除唑来膦酸和多西他赛外,该研究还评价了塞来昔布、阿比特龙和恩杂鲁胺的疗效。初步分析结果显示,

●在III期LUX-Lung 8试验研究中,阿法替尼*比厄洛替尼可显着改善总生存期,阿法替尼可使接受过一线化疗的晚期肺鳞状细胞癌患者的死亡风险降低19% ●与厄洛替尼相比,阿法替尼可明显延缓肺癌进展(主要终点),并提高对癌症相关性咳嗽和呼吸短促症状的控制 ●两种治疗方案的严重不良事件(≥3级)的总发生率相似,并观察到某些特定副作用的发生率存在一定差异 ●计划在今年下半年向全球药物监管部门

ASCO 2015:多个不易治愈癌症的新免疫疗法

芝加哥——今天美国临床肿瘤学会(ASCO)51届年会上公布的四个临床试验结果显示免疫疗法对多种常见固体肿瘤癌症患者是有前途的治疗策略。新的研究结果表明对于晚期肝脏、头颈部,肺部、结直肠癌症以PD-1蛋白为靶标的免疫疗法具有有效性。一些研究还发现基因标记可用于确定哪些患者从这些新疗法中受益最多。“每年靶标为免疫治疗领域的研究都会使人变得更加兴奋”FASCO,医学博士,ASCO专家 Lynn Schu
