2026年3月16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)今日宣布,其自主研发的高选择性口服小分子FGFR4抑制剂依帕戈替尼(Irpagratinib/ABSK-011)联合标准疗法(特瑞普利单抗+贝伐珠单抗生物类似物),已在针对晚期或不可切除肝细胞癌一线治疗的II期临床研究中完成首例患者给药。
原发性肝癌是全球第三大肿瘤相关死亡原因,其中HCC约占75%-85%。目前,免疫检查点抑制剂联合抗血管生成治疗的“靶免联合”方案已成为晚期HCC的一线标准疗法,但临床实践发现,不同分子分型的患者获益存在差异。回顾性研究显示,与FGF19低表达患者相比,FGF19过表达HCC患者接受一线靶免联合治疗后,中位无进展生存期(mPFS)显著缩短(6.1个月 vs 11.4个月),客观缓解率(ORR)呈下降趋势(33.3% vs 45.2%)1。研究认为,这一差异可能与FGFR4/FGF19信号通路异常激活相关。该通路的持续激活可上调PD-L1表达,促进肿瘤免疫逃逸及肿瘤转移,从而削弱免疫联合治疗的疗效2,3。
因此,在标准靶免方案基础上进一步联合FGFR4抑制剂,有望从机制层面增强抗肿瘤效应,为该类患者带来额外临床获益。然而,尽管多达30%的HCC患者存在FGF19过表达,目前却尚无针对该靶点的获批产品,使得这一人群在现有标准治疗体系下仍存在未满足的治疗需求。
依帕戈替尼是和誉医药自主研发的一款高选择性、口服小分子FGFR4抑制剂。在2025年欧洲肿瘤内科学会胃肠道肿瘤大会(ESMO GI)上,和誉公布了依帕戈替尼联合阿替利珠单抗治疗HCC的II期研究数据。结果显示,对于初治及既往接受过免疫检查点抑制剂(ICI)治疗的FGF19过表达患者,观察到超过50%的ORR及超过7个月的mPFS,且整体安全性可控,未出现新的安全性信号1。该研究数据充分展示了依帕戈替尼与免疫治疗的潜在协同增效作用,为后续联合一线标准疗法的临床研究奠定了坚实基础。
基于上述积极研究成果,和誉医药正式启动了依帕戈替尼联合特瑞普利单抗及贝伐珠单抗生物类似物的临床研究,旨在系统评估该三联方案用于FGF19过表达的晚期或不可切除HCC患者一线治疗的安全性、耐受性及初步疗效。
除该研究外,全球范围内也有其他研究者在积极探索依帕戈替尼联合更多标准疗法的新策略。未来,随着更多高质量临床研究的深入推进和数据积累,依帕戈替尼有望为FGF19过表达HCC患者带来新的生存希望,助力HCC诊疗迈向更加精准化、个体化的新阶段。

关于依帕戈替尼(Irpagratinib/ABSK-011)
依帕戈替尼(ABSK-011)是一种高选择性小分子FGFR4抑制剂,被开发用于治疗FGF19过表达的晚期肝细胞癌(aHCC)。研究表明,全球约30%的HCC患者存在FGF19过表达。开发针对该信号通路的靶向疗法代表了治疗HCC的一种新颖的创新方法。
当前,全球尚无FGFR4抑制剂获批上市,根据弗若斯特沙利文的分析,依帕戈替尼凭借其在竞争格局中的领先地位,有望成为首个治疗FGF19过表达HCC患者的突破性药物。
除单药之外,和誉医药同时在探索联合抗PD-L1抗体阿替利珠单抗(由F. Hoffmann-La Roche Ltd.及罗氏(中国)投资有限公司制造)的II期试验。在2025年ESMO-GI大会上,和誉医药发布了联合用药治疗aHCC患者的最新临床试验数据,其中,依帕戈替尼联用阿替利珠单抗队列在初治及既往接受过ICI治疗的FGF19过表达HCC患者中,客观缓解率(ORR)均超过50%,中位无进展生存期(mPFS)超过7个月。
Abbisko Therapeutics' Irpagratinib Combined with Targeted-Immunotherapy Completes First Patient Dosing in Phase II Trial for First-Line Treatment of Advanced HCC
16 March 2026, Abbisko Therapeutics Co., Ltd. ("Abbisko Therapeutics" hereafter, HKEX code: 02256) today announced that the first patient has been dosed in a Phase II study evaluating its independently developed, highly selective, oral small-molecule FGFR4 inhibitor irpagratinib (ABSK-011), in combination with standard of care (toripalimab plus bevacizumab biosimilar) as first-line treatment for patients with advanced or unresectable hepatocellular carcinoma (HCC).
Primary liver cancer ranks as the third leading cause of cancer-related mortality worldwide, with HCC accounting for approximately 75%–85% of cases. Currently, immune checkpoint inhibitors (ICIs) combined with anti-angiogenic therapy have become the standard first-line treatment for advanced HCC. However, clinical practice has shown that treatment outcomes vary among patients with different molecular subtypes.
Retrospective analyses have demonstrated that, compared with patients with low FGF19 expression, those with FGF19 overexpression experienced a significantly shorter median progression-free survival (mPFS) when receiving first-line targeted immunotherapy combinations (6.1 vs. 11.4 months) 1. A downward trend in objective response rate (ORR) was also observed (33.3% vs. 45.2%) 1. This difference may be associated with aberrant activation of the FGFR4/FGF19 signaling pathway. Persistent activation of this pathway can upregulate PD-L1 expression in tumor cells, thereby promoting immune evasion and metastasis, and potentially attenuating the efficacy of immunotherapy-based combinations 2,3.
Therefore, adding an FGFR4 inhibitor to the existing immunotherapy-anti-angiogenic combination regimen may enhance antitumor activity through a complementary mechanism and potentially deliver additional clinical benefit to these patients. However, despite FGF19 overexpression occurring in up to 30% of HCC patients, there are currently no approved therapies targeting this pathway, leaving this population with unmet medical needs under the existing SOC treatment paradigm.
Irpagratinib is a highly selective, orally administered small-molecule FGFR4 inhibitor independently developed by Abbisko Therapeutics that precisely targets the FGFR4/FGF19 signaling pathway. At the 2025 European Society for Medical Oncology Gastrointestinal Cancers Congress (ESMO GI), Abbisko presented Phase II study results of irpagratinib in combination with atezolizumab for the treatment of HCC. In both treatment-naïve patients and those previously treated with ICIs whose tumors exhibited FGF19 overexpression, the combination achieved an ORR exceeding 50% and mPFS of more than 7 months, with a manageable safety profile with no new safety signals observed 1. These findings highlight the potential synergistic activity of irpagratinib with immunotherapy and provide a strong foundation for further studies combining irpagratinib with first-line standard therapy.
Based on these encouraging findings, Abbisko Therapeutics has initiated the clinical study evaluating irpagratinib in combination with toripalimab and bevacizumab biosimilar, aiming to systematically assess the safety, tolerability, and preliminary efficacy of this triplet regimen as a first-line treatment for patients with FGF19-overexpressing advanced or unresectable HCC.
In addition to this study, researchers worldwide are actively exploring new strategies combining irpagratinib with additional SOC therapies. As more high-quality clinical studies progress and additional data accumulate, irpagratinib has the potential to offer new hope for patients with FGF19-overexpressing HCC and help advance the management of HCC toward more precise and personalized treatment.

About Irpagratinib (ABSK-011)
Irpagratinib is a highly-selective FGFR4 small molecule inhibitor designed to target overexpression of the FGF19 signaling pathway. Several epidemiological studies indicate that approximately 30% of HCC patients worldwide exhibit FGF19 overexpression. Development of targeted therapies against FGFR4 represent an innovative and novel approach to the treatment of HCC.
To date, no FGFR4 inhibitor has been granted regulatory approval globally. According to Frost & Sullivan, irpagratinib is expected to become the first breakthrough treatment for the treatment of HCC patients with FGF19 overexpression.
In addition to monotherapy, Abbisko Therapeutics is exploring irpagratinib in combination with atezolizumab, an anti-PD-L1 antibody manufactured by F. Hoffmann-La Roche and Roche (China), in a Phase II study. At the the 2025 ESMO GI Congress, Abbisko presented clinical data showing that the combination of irpagratinib and atezolizumab achieved an objective response rate (ORR) exceeding 50% and a median progression-free survival (mPFS) of more than 7 months in FGF19-overexpressing HCC patients previously treated with immune checkpoint inhibitors.
