brontictuzumab是靶向Notch1并抑制其通路活性的单克隆抗体。ANN ONCOL近期发表了一篇文章,研究brontictuzumab治疗实体瘤患者的最大耐受剂量,安全性,药代动力学,免疫原性以及初步的有效性。

研究纳入的患者为经过选择的实体瘤复发患者。剂量递增队列中多个剂量水平静脉输入brontictuzumab,剂量拓展队列中brontictuzumab剂量为1.5mg/kg每3周(Q3W)。进入拓展队列需要免疫组化验证Notch1通路活化。根据NCI-CTCAE v4.03对不良反应分级,根据RECIST1.1评估有效性。研究最终纳入48例患者。最大耐受剂量为1.5mg/kg(Q3W)。2例患者中观察到剂量限制3级腹泻,1例患者中观察到3级疲劳。最常见的药物相关不良反应为腹泻,疲劳,恶心,呕吐以及AST升高。brontictuzumab表型出非线性药代动力学,半衰期1-4天。36例可评估的患者中有6例出现临床获益:2例为不确定的部分缓解,4例病情稳定时间增加。2例部分缓解患者及4例病情稳定时间延长患者为腺样囊性癌,存在Notch1通路活化。

文章最后认为,brontictuzumab在最大耐受剂量时耐受性良好。主要的毒性为腹泻,是Notch1抑制的结果。在腺样囊性癌伴Notch1通路活化的患者中观察到了疗效。
