根据杜克癌症研究所研究人员的一个小的概念验证研究,向化学疗法利妥昔单抗添加研究抗体似乎恢复了某些对药物对具有天然抗药性的白血病患者的癌症杀伤性能。

该研究于6月28日发表在“PLOS ONE”杂志上,测试了11例慢性淋巴细胞性白血病血液中的新抗体。这为第一阶段临床试验奠定了基础,这项临床试验将于明年开始。

资深作者Edward F. Patz,J.D.,James和Alice Chen Duke放射学教授说:“这项工作建立在早期的发现,即一些患者天然抗化疗药物利妥昔单抗的基础之上。 Patz也是病理学和药理学与癌症生物学系的教授。 “该药物通过免疫机制部分通过触发癌细胞死亡而起作用,在某些人中,这种免疫机制被去激活,我们的抗体基本上重新激活。

在早期的研究中,Patz及其同事发现了一种针对蛋白质的抗体,称为补体因子H或CFH,可用于保护细胞。 Patz的团队发现,具有抗体的人们具有抗癌的天然能力,因为抗体基本上关闭了癌细胞的安全系统,使其更容易受到药物或免疫“战士”的伤害。

该抗体可能对其中一种药物利妥昔单抗有帮助,其用于治疗白血病,但在一些患者中它仅具有有限的作用。为了测试这种方法,Patz及其同事首先根据血液中白血病细胞的分析,首先确定了11位白血病患者是否对利妥昔单抗敏感。当用利妥昔单抗攻击肿瘤细胞时,11例患者中的10例被确定为无反应者。

但是当将研究性CFH抗体加入到利妥昔单抗中时,11名患者中有5名(45%)癌细胞死亡明显增加。

“这是一种组合方法,似乎剥夺了癌细胞的免疫保护,”Patz说。耐利妥昔单抗的患者重新对利妥昔单抗敏感。

Patz说,抗体是在他的实验室开发的,已被Duke授权给Grid Therapeutics;他是联合创始人,对公司有经济利益。抗体计划的第一阶段临床试验将首先靶向实体肿瘤,包括肺癌乳腺癌结肠癌
