汉康生技扩大HCB101
在台湾地区结直肠癌临床项目
早期二线CRC数据显示ORR达50%、
DCR达100%
台湾地区首例患者完成给药,进一步拓展HCB101全球CRC开发;此前在多种治疗方案中已观察到积极缓解,且HCB101联合贝伐珠单抗和化疗显示持久临床获益。
【台北、上海和旧金山 — 2026年10月14日】 — 汉康生技股份有限公司(TWSE:7827)是一家致力于开发用于肿瘤及免疫介导疾病的新一代免疫疗法的全球临床阶段生物技术公司。公司今日宣布,其全球Ib/IIa期HCB101-201研究(NCT06771622)的结直肠癌(CRC)专属队列已在台湾地区完成首例患者给药,进一步拓展公司在二线转移性CRC领域的全球开发项目。
HCB101-201研究的台湾地区扩展部分正在评估HCB101联合标准治疗方案用于二线转移性结直肠癌患者。HCB101是一款基于汉康生技专有FBDB™平台开发、由AI辅助并采用结构指导设计的SIRPα-IgG4 Fc融合蛋白。
此次扩展基于汉康生技申办方发起的二线微卫星稳定型(MSS)CRC队列所观察到的积极早期疗效。在接受HCB101 5 mg/kg或8 mg/kg联合不同标准治疗方案的12例疗效可评估患者中,6例达到部分缓解,另有6例达到疾病稳定;首次疗效评估时的客观缓解率(ORR)为50%,疾病控制率(DCR)为100%。
“这些逐步显现的CRC数据十分重要,因为所观察到的活性并不局限于单一治疗方案。”汉康生技创始人、董事长兼集团首席执行官刘世高博士表示,“我们在多种标准治疗基础方案中均观察到缓解,而台湾地区此前由研究者发起的研究数据也提供了持久疾病控制的补充证据。疗效广度与持久性的结合,进一步增强了我们拓展HCB101二线CRC开发的依据。”
多种二线CRC治疗方案均显示广泛活性
在目前由申办方发起的CRC队列中,以下联合方案均已观察到部分缓解:
HCB101 + 贝伐珠单抗 + 化疗
HCB101 + 西妥昔单抗 + 化疗
HCB101 + 雷莫芦单抗 + FOLFIRI
其中,其中,贝伐珠单抗联合化疗这一联合治疗方案,为申办方发起的研究项目与台湾地区此前由研究者发起研究所获得的临床数据之间提供了尤其具有参考价值的衔接。
在申办方发起的HCB101-201研究3a队列中,4例接受HCB101 8 mg/kg联合贝伐珠单抗和化疗的可评估患者中,2例达到部分缓解、2例达到疾病稳定,对应ORR为50%、DCR为100%。
此外,在台湾地区一项由研究者发起的研究(NCT07204574)中,3例可评估CRC患者接受了较低剂量HCB101 2.56 mg/kg联合贝伐珠单抗和化疗。首次疗效评估时,3例患者均达到疾病控制;其中1例患者持续临床获益已超过63周,另1例患者在疾病进展前维持疾病控制超过48周。
作为临床背景参考,在既往随机二线转移性CRC研究中,贝伐珠单抗联合化疗的ORR约为5%–23%,中位无进展生存期约为5.7–7.3个月。由于研究设计、患者特征、既往治疗及其他因素存在差异,跨研究比较应谨慎解读。
“值得关注的是,这一逐步显现的疗效信号具有一致性。”汉康生技集团总裁兼首席医学官、美国公司首席执行官Alvin Luk博士表示,“在目前由申办方发起的CRC队列中,HCB101联合治疗的ORR达到50%,疾病控制率达到100%,并且在基于抗VEGF、抗EGFR及化疗的不同治疗方案中均观察到缓解。具体就贝伐珠单抗联合化疗而言,我们既在申办方发起的研究中观察到客观缓解,也在台湾地区此前由研究者发起的研究中观察到长期疾病控制。这些数据集仍处于早期且样本量较小,不应直接比较或合并分析,但各项观察结果的一致性支持继续开展前瞻性临床开发。”
从台湾地区早期临床观察迈向全球开发
台湾地区早期由研究者发起的研究所获得的临床观察结果为HCB101在结直肠癌领域的开发提供了重要观察结果,特别是HCB101联合贝伐珠单抗和化疗可能带来持久疾病控制。
HCB101-201研究现已在台湾地区启动患者入组,将上述早期观察进一步纳入汉康生技由申办方发起的全球开发项目,并可在一项多中心临床研究中开展前瞻性评估。
HCB101-201是一项全球、多中心、开放标签的Ib/IIa期研究,旨在评估HCB101在重点实体瘤中的合理联合治疗方案,包括胃癌/胃食管结合部癌、结直肠癌、头颈部鳞状细胞癌和三阴性乳腺癌。

HanchorBio Expands HCB101 Colorectal Cancer Program in Taiwan as Early 2L CRC Data Show 50% ORR and 100% DCR
First patient dosed in Taiwan expands HCB101 CRC development followingpositive responses across multiple treatment regimens and durable clinical benefit with HCB101 plus bevacizumab and chemotherapy
TAIPEI, SHANGHAI, and SAN FRANCISCO — October 14, 2026 — HanchorBio, Inc. (TWSE: 7827), a global clinical-stage biotechnology company developing next-generation immunotherapies for oncology and immune-mediated diseases, today announced that the first patient in Taiwan has been dosed in the colorectal cancer (CRC)-specific cohort of its global Phase 1b/2a HCB101-201 study (NCT06771622), expanding the Company’s global development program in second-line metastatic CRC.
The Taiwan expansion of the HCB101-201 study is evaluating HCB101, an AI-assisted, structure-guided SIRPα-IgG4 Fc fusion protein developed using HanchorBio’s proprietary FBDB™ platform, in combination with standard-of-care regimens in patients with second-line metastatic CRC.
The expansion builds on encouraging early activity across HanchorBio’s sponsor-led second-line microsatellite-stable CRC cohorts. Among 12 efficacy-evaluable patients who received HCB101 at 5 or 8 mg/kg in combination with different standard-of-care regimens, six achieved partial responses and six achieved stable disease, corresponding to a 50% objective response rate (ORR) and 100% disease control rate (DCR) at first assessment.
“The emerging CRC data are important because the activity is not confined to a single regimen,” said Scott Liu, Ph.D., Founder, Chairman, and CEO (Group) of HanchorBio. “We are seeing responses across multiple standard-of-care backbones, while the earlier investigator initiated data from Taiwan provides complementary evidence of durable disease control. That combination of breadth and durability strengthens our rationale to expand HCB101 development in second-line CRC.”
Broad Activity Across Multiple Second-Line CRC Backbones
Across the current sponsor-led CRC cohorts, partial responses have been observed with:
HCB101 + bevacizumab + chemotherapy
HCB101 + cetuximab + chemotherapy
HCB101 + ramucirumab + FOLFIRI
The bevacizumab-plus-chemotherapy combination therapy provides a particularly relevant bridge between the sponsor-led program and earlier investigator-initiated clinical indata from Taiwan.
In sponsor-led HCB101-201 Cohort 3a, four evaluable patients treated with HCB101 8 mg/kg plus bevacizumab and chemotherapy achieved 2 partial responses and 2 stable diseases, corresponding to a 50% ORR and 100% DCR.
Separately, in a Taiwan investigator-initiated study (NCT07204574), three evaluable CRC patients received lower-dose HCB101 2.56 mg/kg plus bevacizumab and chemotherapy. All three achieved disease control at first assessment, including one patient with ongoing clinical benefit beyond 63 weeks and another who maintained disease control for more than 48 weeks before progression.
For clinical context, bevacizumab plus chemotherapy has historically produced ORRs of approximately 5%–23% and median progression-free survival of approximately 5.7–7.3 months in randomized second-line metastatic CRC studies. Cross-trial comparisons should be interpreted cautiously because of differences in study design, patient characteristics, prior therapy, and other factors.
“What stands out is the consistency of the emerging signal,” said Alvin Luk, Ph.D., M.B.A., C.C.R.A., President and Chief Medical Officer (Group) and CEO (U.S.A.) of HanchorBio. “Across our current sponsor-led CRC cohorts, HCB101 combinations have produced a 50% ORR and 100% disease control, with responses across anti-VEGF-, anti-EGFR-, and chemotherapy-based treatment architectures. With bevacizumab plus chemotherapy specifically, we have now seen objective responses in the sponsor-led study together with prolonged disease control in the earlier investigator-initiated study in Taiwan. These remain small, early datasets and should not be directly compared or pooled, but the consistency of the observations supports continued prospective development.”
From Early Taiwan Clinical Observations to Global Development
Early investigator-initiated clinical observations in Taiwan contributed important observations to the development of HCB101 in colorectal cancer, particularly regarding the potential durability of disease control with HCB101 in combination with bevacizumab and chemotherapy.
Initiation of HCB101-201 enrollment in Taiwan now extends those early observations into HanchorBio’s global sponsor-led development program, enabling prospective evaluation within a multicenter clinical study.
HCB101-201 is a global, multicenter, open-label Phase 1b/2a study evaluating HCB101 in rational combinations across prioritized solid tumors, including gastric/GEJ cancer, colorectal cancer, head and neck squamous cell carcinoma, and triple-negative breast cancer.
