诺华CAR-T抗癌新疗法批上市 专家:无法阻止复发

2017-09-01 11:01:14   央广网

央广网北京9月1日消息(记者张奥 实习记者于洋 罗月言)据经济之声《天下公司》报道,瑞士医药巨头诺华公司研发的新型抗癌药物CAR-T获得美国食品药物管理局批准,可以上市销售,这是目前全球首个获批的通过重建癌症患者免疫系统来抗击癌症的治疗方法。CAR-T主要针对急性淋巴性白血病(血液癌),治疗的售价47.5万美元。

癌症的传统治疗方法有手术、放射、化学药物治疗,CAR-T是生物治疗,并且为每个患者量身定制。流程大致是,从患者的血液里提取白细胞,对白细胞进行特化培养,加入抗癌基因,然后回注到患者体内以发现和杀死癌细胞。

周毓说:“CAR-T实际上是一种偏向个性化的治疗,利用患者自身的T细胞,清除癌变细胞,这个过程的原理并不是特别复杂,主要分为几个阶段:从患者身上采血,然后分离一些T细胞,然后做T细胞的改造,然后再激活、扩成很多倍,大量CAR-T细胞回溯到患者身上,利用CAR-T细胞再来攻击癌变细胞。T细胞本身是我们人体免疫细胞中的一种,包括B细胞和其他都是免疫细胞。

周毓认为,理论上,诺华应当会与医院合作:“因为涉及到患者每一个人自己的体细胞,我不知道它使用的是医院的实验室还是回到自己的实验室统一处理之后再到医院进行治疗。以前有采用过使用医院实验室的,但我认为它应该是在统一的实验室对所有的样本进行处理,再回到医院做治疗,因为涉及到运输、质控等,实际是一个相对比较复杂的事情。”

据了解,这个治疗方法高达47万美元。周毓介绍:“最早有预测是在40-70万美金之间,因此还是在预测范围内的。因为它本身就是偏向个性化治疗,类似于定制的意思,所以成本高。再加上前期的研发,另外适用范围实际上还是有限的,所以可能会把价格提高一点。现在CAR-T主要还是针对一些血瘤,血瘤里历史久的,所以人群会少一些,或者说范围比较窄,再摊上早期研发的费用,而且在实体瘤上应答率偏低,所以在实体瘤上没有太好的进展,主要集中在血液瘤上,而血液瘤的发病率是很低的可能。”

它对实体癌症作用一般,但是据诺华介绍,对于血液类癌症的缓解率超过80%。

对此,周毓说:“但是这个复发很快,据说有一半的人都会出现复发。就是说活过半个月的人可能只有60%左右,所以说还是有很多有局限的地方。相比传统的化疗有一些好的进展,但它还是有自身问题存在的,包括副作用比较大。即在没有任何治疗办法的情况下,有一些副作用,但它能帮你延长寿命,所以你肯定会选择去做治疗。也就是说,这个疾病的恶性度比较高,或者说治疗手段太有限、副作用稍微能够接受的情况下,还是会选择接受治疗的。”
