NEJM:Cemiplimab用于晚期皮肤鳞状细胞癌

2018-06-05 zhangfan MedSci原创

免疫检查点抑制剂Cemiplimab可有效缓解晚期皮肤鳞状细胞癌患者症状,其治疗响应率约50%

对于晚期皮肤鳞状细胞癌患者目前尚无有效的系统治疗方法。近日研究人员开展I-II期临床研究,考察了PD-1抑制剂Cemiplimab对转移性皮肤鳞状细胞癌患者的疗效和安全性。

本次研究是Cemiplimab治疗局部晚期或转移性皮肤鳞状细胞癌患者的I期临床研究以及治疗转移性皮肤鳞状细胞癌患者的II期临床研究。患者起始治疗剂量为3mg/Kg体重,每2周1次,每8周接受1次治疗响应评估。主要终点为治疗响应率。

I期研究中,26名患者治疗后13人出现治疗响应,II期研究中,59名患者治疗后28人出现响应。II期研究随访7.9个月,28名响应患者中6个月持续响应率为57%,研究截止时持续响应率为82%。II期研究中,15%的患者出现不良事件,主要是腹泻、疲劳、恶心、便秘和皮疹,7%的患者因不良事件终止治疗。

研究发现,免疫检查点抑制剂Cemiplimab可有效缓解晚期皮肤鳞状细胞癌患者症状,其治疗响应率约50%。
