J Immunother Cancer:纳武单抗辅助治疗III/IV期黑色素瘤的安全性分析

2021-09-02 Nebula MedSci原创

本文汇报了 3 期 CheckMate 238 试验中纳武单抗辅助治疗相关不良事件 (TRAE)的发生情况,并评估了安全性和无复发生存期 (RFS) 之间可能存在的关联

目前,在黑色素瘤辅助治疗的情况下,有几种治疗方案可供选择,了解各种治疗方案的获益-风险概况,有助于制定更好的治疗决策。本文汇报了 3 期 CheckMate 238 试验中纳武单抗辅助治疗相关不良事件 (TRAE)的发生情况,并评估了安全性和无复发生存期 (RFS) 之间可能存在的关联。

在该试验中,手术切除后的 IIIB-C 期或 IV 期黑色素瘤患者接受纳武单抗(3 mg/kg·2周,n=452)或伊匹单抗(10 mg/kg·3周,连续4次后改为每12周一次,n=453)治疗,直到满一年或疾病复发、出现不可耐受的毒性或撤出试验。

纳武单抗组患者接受了中位 24 剂纳武单抗(范围 1-26),伊匹单抗组患者接受了中位 4 剂伊匹单抗(1-7)。纳武单抗组和伊匹单抗组分别有 61% 和 27% 的患者完成了一年疗程。纳武单抗组大部分治疗中断是因为疾病复发(121/177),伊匹单抗组大部分中断治疗是因为药物毒性(208/331)

不同级别不同时间段的TRAE的发生情况

在纳武单抗组,从首剂到最后一剂纳武单抗后100天时间内,所有级别的 TRAE 发生率为 67.7%(1-2级:63.1%;3-4级:4.6%),其中最常见的是腹泻(24.8%)、瘙痒(23.5%)和红疹(20.6%)。TRAE 多发生于前 3 个月(48.0%;最常见的是瘙痒[15.5%]、红疹[15.3%])。大部分 TRAE 在 6 个月内被解决。

有无发生TRAE的患者的无复发生存期

无论是采用里程碑分析,还是在治疗臂内通过Cox模型分析,还是通过与伊匹单抗组进行对比,均未发现 TRAE 的发生与 RFS 之间存在相关性的证据

简而言之,纳武单抗辅助治疗黑色素瘤的安全性分析结果与既往报道的一致。此外,TRAE 的发生与患者的无复发生存期无明显相关性。
