durvalumab联合tremelimumab治疗膀胱癌:无法改善OS

2020-03-08 Allan MedSci原创

阿斯利康近日宣布,一项针对PD-L1抑制剂Imfinzi(durvalumab)的III期研究(单药治疗以及与抗CTLA4抗体tremelimumab联合使用)未能达到主要终点。

阿斯利康近日宣布,一项针对PD-L1抑制剂Imfinzi(durvalumab)的III期研究(单药治疗以及与抗CTLA4抗体tremelimumab联合使用)未能达到主要终点,该项临床试验的主要终点为Imfinzi(durvalumab)治疗无法切除的IV期膀胱癌患者的总体生存(OS)。

在DANUBE试验中,对于肿瘤细胞和/或浸润肿瘤的免疫细胞表达高水平PD-L1的患者,Imfinzi单一疗法不能改善患者的OS,Imfinzi和tremelimumab的组合也不能改善OS,且不论患者肿瘤细胞PD-L1表达水平如何。阿斯利康肿瘤学研发执行副总裁José Baselga表示:“这些结果将为我们全面的膀胱癌III期开发计划提供参考”。膀胱癌泛指各种出自膀胱的恶性肿瘤,也就是有异常细胞大量增殖而不受管制。膀胱是贮存尿液的中空器官,外壁主要由肌肉构成,位于下腹部。最常见的膀胱癌细胞来自膀胱内面黏膜表皮,正式名称为移行上皮细胞癌(TCC)。
