Lancet Oncol:艾瑞恩 vs 比卡鲁胺联合ADT治疗转移性激素阳性前列腺癌

2022-09-09 MedSci原创 MedSci原创

艾瑞恩 (瑞维鲁胺片,Rezvilutamide)是我国恒瑞自主研发的一种新型雄激素受体抑制剂,具有低血脑屏障渗透性,已显示出对转移性去势抵抗性前列腺癌的有效抗肿瘤活性。

艾瑞恩 (瑞维鲁胺片,Rezvilutamide)是我国恒瑞自主研发的一种新型雄激素受体抑制剂,具有低血脑屏障渗透性,已显示出对转移性去势抵抗性前列腺癌的有效抗肿瘤活性。

CHART研究旨在评估艾瑞恩 vs 比卡鲁胺联合雄激素剥夺治疗(ADT)在大体积、转移性、激素阳性的前列腺癌中的疗效和安全性。

这是一项在我国、波兰、捷克共和国和保加利亚的72家医院联合开展的随机、开放标签的3期研究,招募了年满18岁的ECOG表现状态0-1分的大体积、转移性、激素阳性的前列腺癌患者,随机(1:1)接受ADT联合艾瑞恩(240 mg/日)或比卡鲁胺(50 mg/日)治疗。主要终点是无影像学进展生存期和总生存期。


两组的无进展生存率

2018年6月28日-2020年8月6日期间,共筛查了792位患者,其中654位随机接受了艾瑞恩+ADT(n=362)或比卡鲁胺+ADT(n=328)治疗。截止2021年5月16日时(预定的中期分析),中位随访了21.2个月。与比卡鲁胺相比,艾瑞恩显著延长了患者的影像学无进展生存期(中位影像学无进展生存期:未达到 vs 25.1个月;HR 0.44, p<0.0001)。


两组的总生存率

截止2022年2月28日,中位随访了29.3个月。与比卡鲁胺相比,艾瑞恩显著延长了患者的总生存期(中位总生存期均未达到;HR 0.58,p=0.0001)。

最常见的3级及以上的全因不良事件有高血压(艾瑞恩组 vs 比卡鲁胺组:8% vs 24%)、体重增加(6% vs 4%)、贫血(4% vs 5%)和低钾血症(3% vs 1%)。艾瑞恩组和比卡鲁胺组分别有90位和69位患者报告了重度不良反应。艾瑞恩组无治疗相关死亡;比卡鲁胺组有一例未知特殊原因的治疗相关死亡。

综上,与比卡鲁胺联合ADT治疗相比,艾瑞恩联合ADT显著延长了大体积、转移性、激素阳性前列腺癌患者的影像学无进展生存期和总生存期,且安全性可耐受。
