traditional EGFR-TKIs have advanced the treatment landscape of NSCLC with sensitive driver mutations (del19 or L858R), some NSCLC patients with EGFR exon 20 insertion mutations have been left with few effective therapies. The development of novel TKIs is still in progress. Herein, we describe the structure-guided design of a novel selective and orally bioavailable inhibitor, YK-029A, which could overcome both
尽管传统 EGFR-TKI 推进了具有敏感驱动突变(del19或 L858R)的 NSCLC 的治疗前景,但一些具有 EGFR 外显子 20 插入突变的 NSCLC 患者几乎没有有效的治疗方法。新型 TKI 的开发仍在进行中。在此,我们描述了一种新型选择性口服生物可利用抑制剂YK-029A的结构指导设计,它可以克服 T790 M 突变和 EGFR 外显子 20 插入。YK-029A抑制 EGFR 信号传导,抑制 EGFR 驱动的细胞增殖的敏感突变和 ex20ins,并且在体内口服给药基本上有效。此外,YK-029A在 EGFRex20ins 驱动的患者来源异种移植 (PDX) 模型中表现出显着的抗肿瘤活性,在耐受良好的剂量下可防止肿瘤进展或导致肿瘤消退。基于临床前疗效和安全性研究结果,YK-029A将进入治疗EGFRex20ins NSCLC的Ⅲ期临床试验。
