2025年3月24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，已与上海艾力斯医药科技股份有限公司达成协议，（以下简称“艾力斯”，上交所代码：688578）其在研的口服小分子PD-L1抑制剂ABSK043即将与KRAS-G12C抑制剂戈来雷塞片开展联合用药治疗KRASG12C突变的非小细胞肺癌的临床研究。
此前，ABSK043还与艾力斯自主研发的甲磺酸伏美替尼片进行联合用药，用于治疗晚期非小细胞肺癌，并于2024年11月完成首例患者给药。
ABSK043治疗晚期实体瘤患者的最新1期研究结果展示出ABSK043具有良好的安全性和抗肿瘤活性，PD-L1高表达组、EGFR突变组和KRAS突变组的有效率更高。
关于ABSK043
ABSK043为一款全新的具备优异活性及高度选择性的口服小分子PD-L1抑制剂。癌细胞可以利用PD-1及其配体PD-L1这些免疫检查点来逃避免疫监管和清除，抑制或限制T细胞应答。ABSK043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。截止目前，全球已有多款PD-1/PD-L1抗体药物获批上市，但并无PD-1/PD-L1小分子药物获批。ABSK043目前正在澳大利亚和中国开展针对晚期实体肿瘤的I期临床试验。
关于戈来雷塞
枸橼酸戈来雷塞片是一款KRAS G12C抑制剂，目前已在中国、美国及欧洲多国启动多项针对晚期实体瘤患者的临床试验，包括与SHP2抑制剂AST-24082联用治疗非小细胞肺癌，以及单药治疗胰腺癌的注册性临床研究等。其中，胰腺癌适应症在美国获得孤儿药认定，并在中国获得突破性治疗药物认定。
关于艾力斯
上海艾力斯医药科技股份有限公司成立于2004年3月，是一家以全球医药市场需求为导向，专注于肿瘤治疗领域，集新药研发、生产和商业化为一体的创新型制药企业。艾力斯医药以科技关爱生命为发展理念，以开发首创药物和同类最佳药物为首要目标。历经20年坚持不懈的努力，艾力斯已经成功自主研发，获批两款创新药，具备持续创制具有自主产权的疗效确切、市场最优的抗肿瘤新药之综合实力。2020年12月2日，上海艾力斯医药科技股份有限公司正式在上海证券交易所科创板挂牌上市（股票代码：688578）。
Abbisko Therapeutics and Allist Pharmaceuticals Enter into a Cooperation Agreement to Explore ABSK043 in Combination Glecirasib for the Treatment of NSCLC
24 March 2025, Abbisko Therapeutics Co., Ltd. ("Abbisko Therapeutics" hereafter, HKEX code: 02256.HK) today announced it has entered into a cooperation agreement with Shanghai Allist Pharmaceuticals Co., Ltd. ("Allist" hereafter, SSE code: 688578) to explore the combination of Abbisko’s investigational oral PD-L1 inhibitor, ABSK043, with Allist’s KRAS-G12C inhibitor, glecirasib, for the treatment of NSCLC patients with KRAS-G12C mutation.
The parties previously disclosed a separate collaboration to explore the combination of ABSK043 and furmonertinib (IVESA), developed by Allist, for the treatment of advanced non-small cell lung cancer. First-patient dosing for this study occurred in December 2024.
Results from an updated Phase 1 study showed that ABSK043 demonstrated a favorable safety profile and impressive anti-tumor activity as a single agent, with response rates higher in the subset of patients with high PD-L1 expression, and EGFR or KRAS mutations.
About ABSK043
ABSK043 is a novel, orally bioavailable, highly selective small molecule PD-L1 inhibitor wholly-owned by Abbisko Therapeutics. Tumor cells can exploit immune checkpoints such as PD-1 and its ligand PD-L1 to evade immune detection and clearance, thereby suppressing or limiting T-cell responses. ABSK043 selectively binds to the PD-L1 receptor and induces its internalization from the cell surface, effectively inhibiting the PD-1/PD-L1 interaction and alleviating PD-L1-mediated suppression of T-cell activation. In preclinical models, ABSK043 has demonstrated anti-tumor efficacy comparable to approved PD-L1 antibodies. While several PD-1/PD-L1 monoclonal antibodies have been approved worldwide, there are currently no approved orally bioavailable PD-1/PD-L1 small molecule drugs. ABSK043 is currently being explored in an ongoing Phase I clinical trial for advanced solid tumors in Australia and China.
About Glecirasib
Glecirasib (AST-24081) is a KRAS G12C inhibitor. A number of clinical trials are currently ongoing in China, the United States and Europe for patients with advanced solid tumors harboring KRAS G12C mutation. These include combination therapy trials with SHP2 inhibitor AST-24082 in NSCLC and monotherapy trials in pancreatic cancer. Additionally, the pancreatic cancer indication has received orphan drug designation in the United States and breakthrough therapy designation in China.
