机构:天风证券 研究员:杨松/曹文清 事件 公司的PD-L1 小分子抑制剂ABSK043 联合KRAS G12C 抑制剂戈来雷塞片开展联合用药治疗KRAS G12C 突变的NSCLC 的临床研究申请获CDE 批准。此前,公司已经与艾力斯就联合用药达成了合作协 议。 ABSK043 初步临床数据疗效和安全性平衡,联合疗法瞄准近半NSCLC 市场ABSK043 具有FIC 潜力, 全球暂无PD-(L)1 小分子药物上市。ABSK043 是一款口服PD-L1 抑制剂,可与PD-L1 受体特异性结 合并诱导其从细胞表面内吞,有效地抑制PD-1/PD-L1 的相互作用,解除PD-L1 介导的T 细胞活化抑制 作用。ABSK043 在多个临床前模型中展现出与已获批PD-L1 抗体相当的抗肿瘤功效。PD-(L)1 口服 抑制剂研发的一大障碍就是出现周围神经病变的风险更高(如Incyte 的INCB086550),而ABSK043 在 临床试验中展现出良好的安全性和显著的抗肿瘤活性。在共入组77 例患者的实体瘤I 期临床中,87.0% 的患者出现TEAE,其中29.9%为≥3 级,无周围神经病变。 除NSCLC 以外,ABS ...
