2026年3月4日,上海和誉生物医药科技有限公司(以下简称“和誉医药”,港交所代码:02256)宣布,公司在研的口服、高活性、高选择性小分子KRAS G12D抑制剂ABSK141,已在针对携带KRAS G12D突变的晚期实体瘤患者的I/II期临床试验中顺利完成首例患者给药。
KRAS是人类癌症中最常见的致癌驱动基因之一,其中G12D为最主要的突变亚型,广泛存在于胰腺导管腺癌(PDAC)、结直肠癌(CRC)及非小细胞肺癌(NSCLC)等多种实体瘤中。由于G12D突变会引发KRAS蛋白构象发生特异性改变,长期以来被认为是“不可成药”靶点之一,靶向药物开发面临重大挑战,目前全球尚无针对KRAS G12D突变的靶向疗法获批上市。
此次完成首例患者给药的是一项开放标签的I/II期临床研究。该研究已于2025年12月先后获得美国食品药品监督管理局(FDA)及中国国家药品监督管理局(NMPA)新药临床试验(IND)批准。
ABSK141临床研究的顺利推进,标志着和誉医药在KRAS靶向治疗领域迈出重要一步,有望为KRAS G12D突变的实体瘤患者提供变革性治疗选择,重新定义KRAS靶向治疗格局。
关于ABSK141
ABSK141是和誉医药自主设计和开发的新型口服小分子KRAS G12D抑制剂,可以高选择性结合KRAS G12D突变蛋白,从而阻断下游信号通路,抑制肿瘤细胞增殖。临床前研究结果显示,ABSK141在多种动物模型中展现出潜在的同类最佳口服生物利用度,并在包括胰腺导管腺癌(PDAC)和结直肠癌(CRC)在内的多种人源肿瘤细胞系异种移植(CDX)模型中展现出显著的抗肿瘤活性。
Abbisko Therapeutics' Oral Small-Molecule KRAS G12D Inhibitor ABSK141 Completed First Patient Dosing
4 March 2026, Abbisko Therapeutics Co., Ltd. ("Abbisko Therapeutics" hereafter, HKEX code: 02256.HK) today announced that the first patient has been successfully dosed in the Phase I/II clinical study of ABSK141, an oral, highly potent, and selective small-molecule KRAS G12D inhibitor, for the treatment of patients with advanced solid tumors harboring KRAS G12D mutations.
KRAS is one of the most common oncogenic driver genes in human cancers, with G12D being the predominant mutation subtype. It is widely present in various solid tumors such as pancreatic ductal adenocarcinoma (PDAC), colorectal cancer (CRC), and non-small cell lung cancer (NSCLC). The G12D mutation induces specific conformational changes in the KRAS protein, which has long been regarded as an "undruggable" target, posing significant challenges to the development of targeted therapies. To date, no targeted therapy for KRAS G12D mutations has been approved worldwide.
This first-patient dosing was completed in an open-label Phase I/II clinical study. The study received Investigational New Drug (IND) approvals from the U.S. Food and Drug Administration (FDA) and the China National Medical Products Administration (NMPA) in December 2025.
The successful advancement of the ABSK141 clinical study marks an important milestone for Abbisko Therapeutics in the field of KRAS-targeted therapy, and is expected to provide a transformative treatment option for patients with KRAS G12D-mutated solid tumors, redefining the landscape of KRAS-targeted therapy.
About ABSK141
ABSK141 is a novel, oral small-molecule KRAS G12D inhibitor independently designed and developed by Abbisko Therapeutics. It binds selectively to the KRAS G12D mutant protein, thereby blocking downstream signaling pathways and inhibiting tumor cell proliferation. Preclinical studies have demonstrated that ABSK141 possesses potential best-in-class oral bioavailability across multiple animal models and exhibits strong anti-tumor activity in various human cancer cell line-derived xenograft (CDX) models, including pancreatic ductal adenocarcinoma (PDAC) and colorectal cancer (CRC).
