免疫检查点抑制剂
罗氏TIGIT抑制剂组合提高肝癌患者缓解率近4倍
罗氏公布了其TIGIT抗体tiragolumab与目前的一线肝癌疗法Tecentriq/Avastin联用,一线治疗晚期肝细胞癌患者的1b/2期临床试验结果。截至2022年11月28日,tiragolumab+Tecentriq/Avastin组合疗法组中位随访期为14.0个月,对照组(Tecentriq/Avastin)为11.8个月。Tiragolumab三联疗法组的客观缓解率(ORR)为42.5%,是对照组(11%)的接近4倍。Tiragolumab三联疗法组的中位PFS为11.1个月,对照组为4.2个月。在一线疗法中加入tiragolumab让疾病进展和死亡风险降低58%。
针对PD-1抑制剂经治患者,再生元LAG-3组合疗法达到62%客观缓解率
一线治疗肾癌和宫颈癌,Keytruda显著延长患者生命
在治疗晚期宫颈癌的3期临床试验中,Keytruda与化疗联用(加或不加bevacizumab),显著改善患者的总生存期和无进展生存期(PFS)。在中位随访期为 39.1个月时,OS数据如下:
对于PD-L1合并阳性评分为1或更高的患者,Keytruda组为28.6个月,活性对照组为16.5个月。
对于PD-L1合并阳性评分为10或更高的患者,Keytruda组为29.6个月,活性对照组为17.4个月。
对于所有参与者,Keytruda组为26.4个月,活性对照组为16.8个月。
在所有参与者中,Keytruda组的PFS为10.4个月,活性对照组为8.2个月。
