Sci Transl Med:重磅疗法治疗脑瘤,研究展现曙光

2017-07-21 佚名 学术经纬

在一项临床试验中,研究人员们招募了一批表达EGFRvIII,且病情出现复发的胶质母细胞瘤患者。利用这些患者体内的T细胞,研究人员开发出了CAR-T-EGFRvIII疗法,特异性地针对患者的癌细胞。

7月19日,美国前总统奥巴马罕见地在推特上写道:“约翰·麦凯恩是一名美国英雄,也是我见过的最勇敢的斗士之一。癌症根本不知道它面对的是怎样一名对手。约翰,让癌症见鬼去吧!”不到24个小时,这条推文收获了150万个“赞”。



麦凯恩是奥巴马在2008年美国大选中的竞选对手。一天前,他的办公室向外界宣布,这名80岁的老人患有胶质母细胞瘤,一种最为常见,极具侵袭性的脑部肿瘤——很多人在确诊时,肿瘤已经扩散到了脑部的多个区域,因此无法通过手术来完全移除。由于目前没有能有效控制这种疾病的疗法,一项统计数据表明,在手术后病情复发的胶质母细胞瘤患者,大概只能活上6个月。

巧合的是,7月19日,《科学》子刊《Science Translational Medicine》刊登了一篇论文,介绍了一种用T细胞疗法治疗胶质母细胞瘤的策略。发表之后,这篇论文立刻得到了大量关注——这款疗法正是在不久前刷爆整个医药人朋友圈的CAR-T疗法,它的研究人之一是CAR-T疗法的先驱Carl June教授。

先简单介绍一下CAR-T这种T细胞疗法。我们知道,T细胞是人体免疫系统里的战士。它们冲锋陷阵在免疫反应的第一线,有能力对细胞进行杀伤。而这些T细胞的潜在目标之一,就是癌细胞。

为了加强T细胞对癌细胞的杀伤效果,科学家们开发出了一种全新的疗法:他们先从患者体内分离出T细胞,然后利用生物工程的手段改造这些T细胞,使它们表达“嵌合抗原受体”(chimeric antigen receptor,缩写为CAR)。这些受体能特异性地找到癌细胞表面的抗原,帮助T细胞识别。另外,在T细胞识别了癌细胞后,这些受体还能对T细胞进行激活,加强它们的活性。随后,这些经过改造的T细胞在体外不断扩增为一支大军,并最终输回患者体内,向肿瘤发起进攻。

换句话说,“CAR”就好象是T细胞人手一张的通缉令。它们看到癌细胞时,就会毫不留情地展开攻击。

CAR-T疗法的理念自提出后,便得到了诸多专家们的一致看好。几周前,美国FDA的一个评审委员会以“10:0”的投票结果,一致支持诺华(Novartis)公司的CAR-T疗法上市。这也意味着史上首款CAR-T疗法,极有可能在今年问世。

然而由于CAR-T疗法本身的几块短板,几乎没有人想到它有望治疗胶质母细胞瘤。首先,它需要从患者体内提取T细胞,再进行改造。如果患者T细胞的活性不强,CAR-T疗法的效果也会打个折扣。不幸的是,胶质母细胞瘤的患者,正属于这一范畴。

其次,CAR-T疗法的一个潜在副作用是神经毒性。这一副作用会与病发于大脑的胶质母细胞瘤产生怎样的关联,谁都不知道。

第三, 目前来看,CAR-T疗法还局限于白血病淋巴瘤的治疗,它们属于“血液肿瘤”的范畴,与胶质母细胞瘤等“实体肿瘤”有着明显的区别。在实体肿瘤领域,我们还没看到极具说服力的数据,支持CAR-T疗法的效果。

因此,你可以想象,当Carl June教授与他的合作伙伴们在《科学》子刊上发表用CAR-T疗法尝试治疗胶质母细胞瘤的论文时,读者们有多么惊讶!

就像前面说的那样,CAR-T疗法里,科学家们需要改造T细胞,让它们识别癌细胞表面的抗原。对胶质母细胞瘤来说,这一潜在的抗原是EGFR蛋白的一种突变类型EGFRvIII,它是人类肿瘤上最为常见的EGFR变异。在胶质母细胞瘤中,EGFRvIII的表达与疾病的预后直接关联——表达量越高,预后就越差。

在一项临床试验中,研究人员们招募了一批表达EGFRvIII,且病情出现复发的胶质母细胞瘤患者。利用这些患者体内的T细胞,研究人员开发出了CAR-T-EGFRvIII疗法,特异性地针对患者的癌细胞。

初步的结果让研究人员感到满意。他们发现,这款疗法的安全性不错,没有严重的副作用产生。另外,针对EGFRvIII的T细胞,也不会认错人,去识别人体内正常的EGFR蛋白。作为一项早期临床试验,这正是研究人员期盼的结果。

安全性靠谱,那么这款疗法的疗效究竟怎么样呢?由于没有办法直接评估这些经过改造的T细胞是否进入大脑对癌细胞进行杀伤,研究人员们只能用间接的方法,来检测患者脑部的EGFRvIII是否出现了降低。在10名接受T细胞输注的患者中,有7名后续接受了脑部手术,这也让研究人员得以获取脑部的样本,用于比较。研究发现,这7名患者中,有5名患者的EGFRvIII表达水平有较为明显的下降,从一定程度上支持了CAR-T-EGFRvIII疗法的效果。

上文中我们也提到,胶质母细胞瘤患者的病情一旦复发,往往就只有6个月可活。在这项研究里,接受治疗的10名患者,其中位数存活期约为8个月,有小幅提升。不过研究人员也指出,考虑到患者群体之小,该研究中的临床疗效并不作数。确切的疗效还有待进一步验证。

作为一项早期试验,这项研究的意义在于支持了用创新T细胞疗法治疗难治脑部肿瘤的可能性。在这篇论文里,之前关于CAR-T疗法治疗胶质母细胞瘤三个问题,都得到了一定程度的解答:即便是T细胞活性受影响的胶质母细胞瘤患者,其T细胞也足以用来生产CAR-T疗法;这款疗法的安全性有较好的保障;在胶质母细胞瘤的治疗中,研究人员也看到了可喜的迹象。

以PD-1通路抑制剂为代表的肿瘤免疫疗法后,CAR-T疗法正在掀起一场癌症治疗的全新风暴。我们期待读到更多好消息,也祝愿更多创新疗法能够问世,彻底减少癌症对人类的威胁。

CAR-T疗法里程碑:诺华CTL-019获10:0全票通过,FDA专家一致推荐

7月12日,诺华公司的突破性嵌合抗原受体T细胞疗法(CAR-T)Tisagenlecleucel(CTL-019)获美国 FDA 咨询专家委员会(ODAC)的一致投票(10-0)支持批准。CTL-019申请的适应症是复发或难治性儿童和年轻成人急性淋巴细胞白血病(ALL),在绝大多数情况下,FDA都会遵从专家咨询委员会的意见,也就是说,CTL-019将大概率成为全球首个获批上市的CRA-T疗法。

 2017年6月3日/生物谷BIOON/---瑞士诺华公司(NVS)公布了一项对CTL119的试验结果,其良好的治疗结果令人吃惊。CTL119是一种正处于试验阶段的CAR-T疗法。在早期的研究中,9名在Imbruvica治疗半年后没有缓解的复发/难治性慢性淋巴细胞白血病(CLL)患者接受了CTL119的治疗。在接受治疗3个月后,其中的8名患者骨髓中没有检测到CLL,另外1名患者部

Nature:让CAR-T疗法更“牛”,这10个方向或许你该看看

T细胞过继转移是一项关键的抗癌技术。想要这类疗法真正用于患者疾病治疗,需要在靶点鉴定、受体设计、T细胞分化、基因工程、细胞生产、政策监管等多个方面取得进展。这类免疫疗法是免疫学、遗传学、合成生物学、干细胞生物学和一系列生产技术的融合。 5月24日,来自纪念斯隆-凯特琳癌症中心和Fred Hutchinson 癌症研究中心的3位科学家在Nature杂志上发表了题为“Therapeutic T
