2017年11月,发表在《J Clin Oncol》的Ib期KEYNOTE-028试验,考察了派姆单抗在晚期、程序性死亡配体1(PD-L1)阳性宫颈癌患者中的安全性和有效性。

2017年11月,发表在《J Clin Oncol》的Ib期KEYNOTE-028试验,考察了派姆单抗在晚期、程序性死亡配体1(PD-L1)阳性宫颈癌患者中的安全性和有效性。

目的:KEYNOTE-028试验(ClinicalTrials.gov编号:NCT02054806)的设计目的是评价派姆单抗在20个PD-L1阳性、晚期实体瘤队列中的安全性和有效性。在此,研究者展示了晚期宫颈癌患者队列的结果。

方法:患者每2周接受派姆单抗10 mg/kg治疗,为期24个月。前6个月每8周和随后每12周,评价应答情况。主要终点为调查者根据实体瘤应答评价标准1.1版评价的总缓解率。安全性为次要终点。

结果:宫颈癌队列中纳入24例患者。中位年龄为42岁(范围,26至62岁),22例患者(92%)接受过既往放疗,15例患者(63%)接受过2线或多线疗法治疗晚期疾病,包括贝伐单抗(10/24)。在数据截止时,中位随访期为11.0个月(范围,1.3至32.2个月)。总缓解率为17%(95% CI,5%至37%);4例患者(17%)实现了证实的部分缓解,3例患者(13%)病情稳定。4例实现部分缓解的患者的中位缓解持续时期为5.4个月(4.1至7.5个月)。18例患者(75%)经历治疗相关不良事件(AEs);≥10%的患者仅发生皮疹(n=5;21%)和发热(n=4;17%)。5例患者经历3级治疗相关AEs。没有观察到4级治疗相关AEs或死亡。

结论:在PD-L1阳性晚期宫颈癌患者中,派姆单抗显示抗肿瘤活性,并展现出与在其他肿瘤类型中一致的安全性。
