Opdivo/Yervoy组合显著提高去势抵抗性前列腺癌患者响应率

2019-02-18 不详 MedSci原创

BMS公布了其关键临床试验CheckMate-650的结果,该试验显示Opdivo与Yervoy联合使用显著提高对转移性去势抵抗性前列腺癌患者的响应率。

BMS公布了其关键临床试验CheckMate-650的结果,该试验显示Opdivo与Yervoy联合使用显著提高转移性去势抵抗性前列腺癌患者的响应率。

在第二代激素治疗且未进行化疗的32例患者中,Opdivo与Yervoy联合的客观响应率(ORR)为25%。在基于紫杉烷的化疗后疾病进展的30例患者中,ORR为10%。

在这两组实验中,部分患者中可以观察到明显提高的反应率,包括具有高肿瘤突变负荷的患者和具有同源重组缺陷的患者。

德克萨斯大学MD安德森癌症中心泌尿生殖肿瘤学和免疫学教授Padmanee Sharma说:"CheckMate -650的结果为开发用于治疗前列腺癌的联合免疫检查点疗法提供了强有力的理论依据。"

"这项研究的临床结果令人鼓舞,并为更大的患者群体中的联合策略提供了基础。"

Opdivo是一种程序性死亡-1(PD-1)免疫检查点抑制剂,旨在特异性地调控自身免疫系统以恢复抗肿瘤免疫反应。

前列腺癌是男性第二位最常见癌症,2018年全球新诊断出近128万病例。与早期前列腺癌不同的是,去势抵抗性前列腺癌(CRPC)即使体内睾酮的量降低,癌症仍然继续增长。
