近日,在医学权威杂志JCO上面发表了一篇研究文章,该文章旨在探讨派姆单抗治疗PD-L1阳性复发或转移性鼻咽癌(RM-NPC)患者的安全性及抗肿瘤活性。

近日,在医学权威杂志JCO上面发表了一篇研究文章,该文章旨在探讨派姆单抗治疗PD-L1阳性复发或转移性鼻咽癌(RM-NPC)患者的安全性及抗肿瘤活性。

方法:
此研究采用非随机、多队列、Ib期临床试验,研究对象为接受派姆单抗治疗的pd-L1-阳性晚期实体瘤患者。鼻咽癌(NPC)队列研究对象的纳入标准包括手术不能切除或转移性疾病、先前标准治疗失败、pd-L1表达1%或更多的肿瘤细胞/肿瘤浸润淋巴细胞。这些患者接受派姆单抗10 mg/kg治疗,每2周一次,共两年/直到疾病恶化/出现不可接受的毒性。主要观察终点为每名调查人员回顾的客观回应率(ORR)。研究人员根据实体瘤的反应评价标准对肿瘤的反应进行评估(RECIST;版本1.1),前6个月每隔8周一次,此后每隔12周一次。

结果:
这项研究共有27名患者接受派姆单抗治疗。中位年龄为52.0岁(范围:18至68岁)。其中92.6%患者之前接受过RMM-NPC治疗;70.4%的患者接受了三种或更多的治疗。在20个月的中位随访中,在7例患者中观察到了部分应答,14例患者中观察到稳定疾病,ORR为25.9%(95% CI:11.1-46.3)。经中央回顾ORR是相似的(26.3%)。15%及以上的患者发生与药物相关的不良事件,包括皮疹(25.9%)、瘙痒(25.9%)、疼痛(22.2%)、甲状腺功能减退(18.5%)和疲劳(18.5%)。8例患者(29.6%)发生与药物相关的≥3级不良事件,其中有一例患者发生与药物相关的死亡(败血症)。数据截止日期为2016年6月20日,两名患者仍在服用派姆单抗治疗。

结论:
派姆单抗对PD-L1阳性复发或转移性鼻咽癌(RM-NPC)患者表现出抗肿瘤活性和易控制的安全性。
