2021-10-14 Allan MedSci原创

近日,安进公布了一项早期研究的最新结果,该研究评估了Lumakras(sotorasib)与十多种不同药物联合治疗KRAS G12C突变癌症的有效性和安全性(图1)。

近日,安进公布了一项早期研究的最新结果,该研究评估了Lumakras(sotorasib)与十多种不同药物联合治疗KRAS G12C突变癌症的有效性和安全性(图1)。

图1.Ib期CodeBreaK 101 研究的测试药物

Ib期CodeBreaK 101 研究的一个分支——评估Lumakras联合afatinib——招募了33名经过大量先前治疗的KRAS G12C突变非小细胞肺癌 (NSCLC) 患者,包括之前接受过Lumakras单一疗法治疗的5名患者。

研究人员给予10名患者20毫克afatinib联合960毫克Lumakras,而23名患者接受30毫克afatinib和960毫克Lumakras。数据显示,第一队列的总体缓解率 (ORR) 为20%,第二队列的ORR)为35%,两个队列的疾病控制率分别为70%和74%。

与此同时,另一组测试了Lumakras联合trametinib在KRAS G12C突变实体瘤患者(包括以前接受过 KRAS G12C抑制剂治疗的患者)中的有效性和安全性。该组共纳入41名患者,其中18名非小细胞肺癌患者、18名结直肠癌 (CRC) 患者和 5名其他实体瘤患者。

在未接受KRAS G12C抑制剂治疗的CRC患者中,9%实现了部分缓解,82%实现了疾病控制。同时,14%的既往接受过治疗的CRC患者实现了部分缓解,86%的患者实现了疾病控制。

在NSCLC人群中,20%的KRAS G12C抑制剂初治患者实现了部分缓解,87%实现了疾病控制。在之前接受过KRAS G12C抑制剂治疗的患者中,67%的患者实现了疾病控制。

安进研发执行副总裁 David M. Reese 说:“安进将考虑这些afatinib和trametinib的结果。我们期待在未来几个月内展示更多数据,包括与PD-1抑制剂联合的数据集”。
