2025年美国临床肿瘤学会(ASCO)年会将于5月30日-6月3日在美国芝加哥隆重召开。本届学术会议上,复宏汉霖将重磅发布公司创新管线中近二十项研究进展,覆盖HLX43(PD-L1靶向ADC)、HLX22(抗HER2单抗)、H药汉斯状®(抗PD-1单抗,斯鲁利单抗)等创新分子的最新/更新研究数据。HLX43(PD-L1靶向 ADC)其中HLX43是一款靶向程序性死亡-配体1(PD-L1)的新型ADC候选药物,由全人源IgG1抗PD-L1抗体与创新连接子-拓扑异构酶抑制剂荷载偶联而成,其药物抗体比(drug-to-antibody ratio, DAR)约为8。HLX43兼具毒素精准杀伤和肿瘤免疫作用的复合功能,其毒素不仅能够藉靶点内吞进入肿瘤细胞后进行释放,并在肿瘤微环境中释放后借助旁观者效应进入肿瘤细胞,阻断DNA复制,从而导致肿瘤细胞凋亡。此外,HLX43的PD-L1靶向抗体可激活免疫调节机制,发挥协同抗肿瘤效应。临床前研究表明,HLX43在单药及联合治疗中均展现出显著抗肿瘤活性,有望为PD-1/PD-L1疗法耐药或无效的恶性肿瘤患者提供全新的治疗选择。HLX22(抗HER2单抗)HLX22是一款靶向HER2的创新型单克隆抗体,可结合在HER2的胞外亚结构域IV,但结合表位与曲妥珠单抗有所不同,使得该产品能够与曲妥珠单抗同时结合至HER2,促进HER2二聚体(HER2同源二聚体及HER2/EGFR异源二聚体)的内吞和降解,进而产生更强的HER2受体阻断效果。HLX22联合汉曲优®(曲妥珠单抗,美国商品名:HERCESSI™,欧洲商品名:Zercepac®)治疗HER2阳性胃癌的II期临床研究结果显示,在汉曲优®联用化疗的基础上加入HLX22可提高HER2阳性G/GEJ癌患者一线治疗的生存期和抗肿瘤反应,且安全性可控。目前,HLX22联合曲妥珠单抗及化疗一线治疗HER2阳性晚期胃癌的国际多中心III期临床研究(HLX22-GC-301)分别获得中国、美国、日本和澳大利亚等地药监机构的新药临床试验(IND)许可,并完成首例患者给药。此外,HLX22于2025年获得美国食品药品监督管理局(FDA)授予的孤儿药资格认定(Orphan Drug Designation, ODD),用于胃癌的治疗。继胃癌之后,HLX22与德曲妥珠单抗的联合疗法已拓宽至乳腺癌疾病领域,有望为更多肿瘤患者带来新的治疗选择。H药 汉斯状®(抗PD-1单抗,斯鲁利单抗)H药 汉斯状®为重组人源化抗PD-1单抗注射液(通用名:斯鲁利单抗注射液),是全球首个获批一线治疗小细胞肺癌的抗PD-1单抗,已在中国、欧盟以及多个东南亚国家获批上市。聚焦肺癌和消化道肿瘤,复宏汉霖积极推进H药与公司其他产品的协同以及与创新疗法的联合,截至目前,H药已在中国获批用于治疗鳞状非小细胞肺癌(sqNSCLC)、广泛期小细胞肺癌(ES-SCLC)、食管鳞状细胞癌(ESCC)和非鳞状非小细胞肺癌(nsNSCLC)。H药治疗SCLC也已获得美国FDA和欧盟EC的孤儿药资格认定,并在美国积极推进一项H药对比一线标准治疗阿替利珠单抗的头对头桥接试验。H药的4项关键性临床研究结果分别发表于知名期刊《美国医学会杂志》(JAMA)、《自然-医学》(Nature Medicine)、Cancer Cell和British Journal of Cancer。此外,H药还荣获《CSCO 小细胞肺癌诊疗指南》、《CSCO非小细胞肺癌诊疗指南》、《CSCO 食管癌诊疗指南》、《CSCO免疫检查点抑制剂临床应用指南》和《中国食管癌放射治疗指南》等多部权威指南推荐,为肿瘤临床诊疗提供重要参考。关于复宏汉霖复宏汉霖(2696.HK)是一家国际化的创新生物制药公司,致力于为全球患者提供可负担的高品质生物药,产品覆盖肿瘤、自身免疫疾病、眼科疾病等领域,已有6款产品在中国获批上市,4款产品在国际获批上市,5个上市申请分别获中国药监局、美国FDA和欧盟EMA受理。自2010年成立以来,复宏汉霖已建成一体化生物制药平台,高效及创新的自主核心能力贯穿研发、生产及商业运营全产业链。公司已建立完善高效的全球创新中心,按照国际药品生产质量管理规范(GMP)标准进行生产和质量管控,不断夯实一体化综合生产平台,其中,公司商业化生产基地已相继获得中国、欧盟和美国GMP认证。复宏汉霖前瞻性布局了一个多元化、高质量的产品管线,涵盖约50个分子,并全面推进基于自有抗PD-1单抗H药汉斯状®的肿瘤免疫联合疗法。截至目前,公司已获批上市产品包括国内首个生物类似药汉利康®(利妥昔单抗)、自主研发的中美欧三地获批单抗生物类似药汉曲优®(曲妥珠单抗,美国商品名:HERCESSI™,欧洲商品名:Zercepac®)、汉达远®(阿达木单抗)、汉贝泰®(贝伐珠单抗)、全球首个获批一线治疗小细胞肺癌的抗PD-1单抗汉斯状®(斯鲁利单抗,欧洲商品名:Hetronifly®)以及汉奈佳®(奈拉替尼)。公司亦同步就19个产品在全球范围内开展30多项临床试验,对外授权全面覆盖欧美主流生物药市场和众多新兴市场。Henlius to Present Latest Research Results at ASCO 2025The 2025 American Society of Clinical Oncology (ASCO) Annual Meeting will be held in Chicago, USA, from May 30 to June 3. Henlius will showcase about 20 latest/updated research achievements on innovative products at the conference, covering HLX43 (PD-L1-targeted ADC), HLX22 (anti-HER2 monoclonal antibody), and HANSIZHUANG (serplulimab, anti-PD-1 monoclonal antibody). HLX43 (PD-L1-Targeting ADC)HLX43 is a novel PD-L1-targeting ADC, composed of a fully humanized anti-PD-L1 IgG1 antibody, a novel tripeptide linker and topoisomerase inhibitor payload. The drug to antibody ratio (DAR) is around 8. Its mechanisms of action integrates targeted cytotoxic delivery and immune checkpoint activation through PD-L1/PD-1 blockade. Upon binding to PD-L1-expressing tumor cells, HLX43's cytotoxic payload can be delivered into tumor cells via dual mechanisms—First, the ADC undergoes receptor-mediated endocytosis, releasing the cytotoxic payload intracellularly via linker cleavage, and the payload further diffuses into neighboring tumor cells via bystander effect, thereby blocking DNA replication and triggering tumor cell apoptosis. Meanwhile, the anti-PD-L1 antibody of HLX43 activates immune modulation and blocks immune checkpoints, driving synergistic antitumor efficacy. Preclinical studies have demonstrated that, HLX43 exhibits significant antitumor activity both as a monotherapy and in combination with serplulimab, potentially offering a promising therapeautic option for tumour patients who do not respond to or develop resistance to PD-1/PD-L1-targeted therapy.HLX22 (anti-HER2 mAb)HLX22, an innovative anti-HER2 mAb, can bind to HER2 extracellular subdomain IV at a binding site different from that of trastuzumab, which allows simultaneous binding of HLX22 and trastuzumab to HER2 dimers (HER2 homodimer and HER2/EGFR heterodimer) on tumour cell surface, thereby promoting the internalization and HER2 dimer degradation. The phase 2 clinical data on the combination of HLX22 and HANQUYOU (trastuzumab, trade name: HERCESSI™ in the U.S., Zercepac® in Europe) demonstrate that the addition of HLX22 to HANQUYOU plus chemotherapy significantly improves survival and anti-tumour efficacy in first-line treatment of HER2-positive gastric/gastroesophageal junction cancer (GC/GEJC) patients, with manageable safety profiles. At present, the Investigational New Drug (IND) applications for HLX22-GC-301, a phase 3 clinical study aims to evaluate the efficacy and safety of HLX22 in combination with trastuzumab and chemotherapy for the first-line treatment of patients with HER2-positive metastatic GC/GEJC, have been approved by regulatory authorities in China, the U.S, Japan and Australia, etc., and this international study has been initiated in multiple countries and regions worldwide and has completed its first patient dosing globally. Furthermore, HLX22 has received orphan drug designation (ODD) in 2025 from the U.S. Food and Drug Administration (FDA) for the treatment of gastric cancer. Currently, the therapeutic scope of HLX22 has further expanded to the field of breast cancer apart from its exploration in gastric cancer, potentially providing new treatment options for broader tumour patients population.HANSIZHUANG(serplulimab, anti-PD-1 mAb)HANSIZHUANG (recombinant humanized anti-PD-1 monoclonal antibody injection, generic name: serplulimab injection) is the first anti-PD-1 mAb for the first-line treatment of SCLC and has been approved in China, the EU and several SEA countries. Focusing on lung and gastrointestinal cancer, the synergy of HANSIZHUANG with in-house products of the company and innovative therapies are being actively promoted. Up to date, HANSIZHUANG has been approved by the National Medicinal Products Administration (NMPA) for the treatment of squamous non-small cell lung cancer (sqNSCLC), extensive-stage small cell lung cancer (ES-SCLC), esophageal squamous cell carcinoma (ESCC) and non-squamous non-small cell lung cancer (nsNSCLC). Serplulimab was granted orphan drug designations by the FDA and the EC for the treatment of SCLC, and its bridging head-to-head trial in the United States to compare HANSIZHUANG to standard of care atezolizumab (anti-PD-L1 mAb) for the first-line treatment of ES-SCLC is well under way.The results of 4 pivotal trials of HANSIZHUANG were published in the Journal of the American Medical Association (JAMA), Nature Medicine, Cancer Cell and British Journal of Cancer, respectively. Furthermore, HANSIZHUANG was respectively recommended by the CSCO Guidelines for Small Cell Lung Cancer, the CSCO Guidelines for Non-Small Cell Lung Cancer, the CSCO Guidelines for Esophageal Cancer, the CSCO Clinical Practice Guidelines on Immune Checkpoint Inhibitor, the China Guidelines for Radiotherapy of Esophageal Cancer, and other definitive guides, providing valuable references for clinical diagnosis and treatment of tumours.About HenliusHenlius (2696.HK) is a global biopharmaceutical company with the vision to offer high-quality, affordable and innovative biologic medicines for patients worldwide with a focus on oncology, autoimmune diseases and ophthalmic diseases.
