FDA批准Keytruda作为MSI-H / dMMR转移性结直肠癌的一线疗法

2020-06-30 Allan MedSci原创

美国FDA今日批准Keytruda(pembrolizumab)作为微卫星不稳定性高(MSI-H)或错配修复缺陷(dMMR)转移性结直肠癌患者的一线疗法。

美国FDA今日批准Keytruda(pembrolizumab)作为微卫星不稳定性高(MSI-H)或错配修复缺陷(dMMR)转移性结直肠癌患者的一线疗法。MSI-H的频率随肿瘤类型和阶段而异,大约5%的转移性结直肠癌患者患有MSI-H或dMMR肿瘤。这项批准是基于一项多中心、开放标签随机试验的最新结果。该研究表明,Keytruda组的中位PFS为16.5个月,标准护理组的中位PFS为8.2个月。

FDA肿瘤学卓越中心主任Richard Pazdur博士说:“转移性结直肠癌是一种严重且威胁生命的疾病,预后较差。目前可用的化学和生物制剂疗法均具有明显的毒性,免疫疗法被批准作为一线疗法标志着治疗范式的转变”。

Keytruda能够靶向人体免疫细胞和某些癌细胞上的PD-1 / PD-L1。通过阻止这种途径,Keytruda可以帮助人体的免疫系统对抗癌细胞,并为MSI-H或dMMR转移性结直肠癌患者带来益处。FDA先前已批准Keytruda治疗其他类型的癌症。
