JCO:抗体偶联药物——IMMU-132治疗晚期非小细胞肺癌的安全性及有效性

Trop-2亦称作肿瘤相关钙信号传导蛋白-2(tumor-associated calcium signal transducer 2,TAC-STD2),最早发现表达于滋养层上皮细胞,在胚胎发育过程中有重要作用,随着对其研究的深入,Trop-2在多种上皮来源的肿瘤组织中高表达,但在相对应的正常组织中却几乎无表达,其可能是非小细胞肺癌(Non-Small-Cell Lung Cancer,NSCL

Trop-2亦称作肿瘤相关钙信号传导蛋白-2(tumor-associated calcium signal transducer 2,TAC-STD2),最早发现表达于滋养层上皮细胞,在胚胎发育过程中有重要作用,随着对其研究的深入,Trop-2在多种上皮来源的肿瘤组织中高表达,但在相对应的正常组织中却几乎无表达,其可能是非小细胞肺癌(Non-Small-Cell Lung Cancer,NSCLC)的抗体偶联药物(Antibody-Drug Conugate,ADC)的靶向目标。

发表在最新一期的JCO上的一篇研究介绍了研究人员对sacituzumab govitecan(IMMU-132)——一个靶向SN-38的Trop-2 ADC的研究进展。

在一项单臂、多中心试验中,转移性非小细胞肺癌的治疗前患者在21天为一周期的第1和8天接受8或10mg/kg IMMU-132。主要终点是安全性和客观反应率(ORR)。次要终点为无进展生存期和总生存期。

54例患者参与了该研究。在响应评估研究人群(n = 47)中,ORR为19%;平均响应时间为6个月(95% CI,4.8-8.3个月);临床受益率(完全缓解+部分缓解+疾病稳定≥4月),43%。意向治疗(ITT)人群的ORR为17%(54例中的9例)。响应发生的中位时间为3.8月,包括患者复发或进展后,免疫关卡抑制剂疗法。ITT的中位无进展生存期为5.2个月(95% CI,3.2-7.1个月),ITT的中位总生存期为9.5个月(95% CI,5.9-16.7个月)。3级不良事件及更高级不良事件包括中性粒细胞减少症(28%),腹泻(7%),恶心(7%),疲劳(6%),中性粒细胞减少性发热(4%)。一名患者出现短暂的免疫反应,该患者的中位剂量是10剂。免疫组织化学法发现26个可利用的肿瘤标本里超过90%的为Trop-2高阳性(2 +,3 +),这表明TROP-2不是预测响应的生物标志物。

IMMU-132在转移性非小细胞肺癌的治疗期重症患者中的耐受性良好且响应持久。该抗体偶联药物应在trop-2表达的肿瘤患者中被进一步研究。
