智通财经APP获悉,默沙东(MRK.US)周四宣布,其最畅销的治疗药物Keytruda作为联合治疗方案的一部分,在一项针对特定类型卵巢癌的3期试验中达到了主要终点。

默沙东表示,KEYNOTE-B96试验达到了Keytruda联合化疗(联合/不联合bevacizumab)的无恶化生存期(PFS)的主要终点,bevacizumab/Avastin是罗氏公司销售的一种癌症药物。根据默沙东的说法,这项随机试验涉及了铂耐药复发卵巢癌(PROC)患者,在肿瘤标志物PD-L1的患者和整个研究人群中达到了PFS终点。KEYNOTE-B96也达到了PD-L1肿瘤患者总生存期的次要目标,但并不适用于所有患者。

然而,该研究将继续进行,直到未来的分析能够测试药物组合是否满足整个研究人群的OS终点。该公司指出,该数据首次表明基于keytruda的治疗方案延长了PROC患者的生存期。抗PD -1疗法尚未被批准用于卵巢癌。

至于KEYNOTE-B96的耐受性数据,默沙东表示,Keytruda的安全性与之前的研究结果一致,没有新的安全性信号。该公司预计将在未来的医疗活动中提交结果,并提交给全球监管机构进行审查。
