汉康生技将于2026年
ASCO消化道肿瘤大会
发表HCB101联合标准疗法
二线治疗胃癌的早期临床数据
早期剂量依赖性抗肿瘤活性表明HCB101有望成为与现有标准疗法协同的先天免疫骨干(backbone)疗法
【台北、上海、旧金山,2026年1月6日】—汉康生技股份有限公司,一家专注于开发下一代肿瘤与自体免疫疾病免疫疗法的全球临床阶段生物技术公司,昨日宣布其HCB101联合标准疗法(SoC)在晚期胃癌患者中的Phase 1b/2a临床试验数据,已获选以壁报形式在2026年美国临床肿瘤学会消化道肿瘤大会(ASCO GI 2026)上发表。该会议将于2026年1月8日至10日在美国旧金山举行。
本次入选的摘要(编号:372)报告显示,在一线治疗后进展的晚期胃腺癌患者中,HCB101联合雷莫西尤单抗与紫杉醇展现出具有剂量依赖性的早期抗肿瘤活性,且安全性可控。尽管仍属早期临床阶段,观察到的缓解率与肿瘤缩小程度已优于历史上二线标准治疗的数据,包括全球RAINBOW及RAINBOW-Asia(NCT01939899)临床试验中雷莫西尤单抗联合紫杉醇的表现,支持以此HCB101为基础的联合疗法进一步推进临床开发。
二线胃癌在全球属于临床路径明确、应用成熟的标准治疗领域,但整体疗效仍相当有限。HCB101的设计理念在于“增强而非颠覆”现有治疗框架,通过激活先天免疫反应,同时保持标准剂量、安全性预期与临床操作流程,使其能无缝融入既有的治疗模式。

该Phase 1b/2a试验的更多分析与数据将于ASCO GI 2026壁报环节中同步展示。
汉康生技创始人、董事长兼首席执行官刘世高博士表示:
“CD47–SIRPα在肿瘤免疫逃逸中的作用机制早已被充分理解,但将其转化为临床有效的疗法始终充满挑战。HCB101自设计之初即借助AI技术突破这一难题。我们开发的工程化SIRPα具有显著提升的CD47结合亲和力,同时避免了早期疗法常见的血液学毒性。当HCB101与已获验证且商业成熟的二线胃癌标准治疗联合使用时,我们反复观察到剂量依赖性的抗肿瘤活性。这为‘先天免疫调控可作为高兼容性免疫治疗骨干’提供了清晰的临床例证。”
以“骨干(backbone)疗法”为核心的作用机制
HCB101是一款工程化SIRPα–Fc融合蛋白,可选择性阻断CD47–SIRPα先天免疫检查点,恢复巨噬细胞对肿瘤细胞的吞噬作用,同时最大程度降低与红细胞的结合,使其特别适合与现有疗法联合使用。 在二线胃癌标准治疗中,雷莫西尤单抗可促进肿瘤血管正常化并减轻VEGF介导的免疫抑制,紫杉醇则能诱导免疫原性细胞死亡与抗原释放。该组合使先天免疫激活能够自然融入已验证的标准治疗体系,形成具有生物学一致性且临床可行的抗肿瘤策略。
汉康生技集团总裁兼医疗长、美国子公司首席执行官陆英明博士表示:
“二线胃癌具备明确的临床路径与广泛使用的治疗方案。本次早期数据最令人振奋的,不仅是HCB101联合雷莫西尤单抗与紫杉醇所展现的缓解深度与频率,更在于这些疗效是在不牺牲现有治疗安全性与临床可操作性的前提下实现的。我十分期待在ASCO GI分享这些结果,并与临床学界共同探讨其对胃癌治疗中先天免疫角色的更广泛启示。”
关于 HCB101
HCB101是基于汉康生技FBDB™平台理性设计的SIRPα–IgG4 Fc融合蛋白,可选择性阻断CD47–SIRPα先天免疫检查点,同时将血液毒性降至最低。与早期抗CD47疗法不同,HCB101的设计在保留巨噬细胞抗肿瘤活性的同时,避免了对红细胞与血小板的过度结合,从而克服了以往临床开发中的主要限制。
此外,HCB101在设计上即注重联合治疗的兼容性。其安全性、受体占有率与药理学特性支持其无缝整合至现有肿瘤治疗方案中,在不干扰标准剂量、安全预期与临床流程的前提下启动先天免疫应答。迄今为止,HCB101已在单药及联合治疗的临床与转化研究中表现出一致的靶点结合与早期抗肿瘤活性,包括在以往被认为对CD47靶向疗法具有挑战性的肿瘤类型中。这些特性使HCB101成为一款具有差异化潜力的巨噬细胞检查点骨干疗法,可广泛应用于经过验证的实体瘤与血液肿瘤治疗框架中。

HanchorBio to Present Encouraging Early Clinical Activity of HCB101 in Combination with Standard-of-Care Therapy for Second-Line Gastric Cancer at ASCO GI 2026
Early dose-dependent activity supports HCB101 as an innate-immune backbone therapy complementary to the standard second-line gastric cancer treatment
[Taipei, Shanghai, and San Francisco | January 6, 2026]—HanchorBio, Inc. (TPEx: 7827), a global clinical-stage biotechnology company advancing next-generation immunotherapies for oncology and autoimmune diseases, announced that clinical data from its ongoing Phase Ib/IIa study of HCB101 in combination with standard-of-care (SoC) therapy, including ramucirumab and paclitaxel in second-line (2L) gastric cancer, have been accepted for poster presentation at the American Society of Clinical Oncology Gastrointestinal Cancers Symposium (ASCO-GI) 2026, January 8–10, 2026, in San Francisco.
The accepted abstract (Abstract ID: 372) reports encouraging early, dose-dependent antitumor activity and a manageable safety profile in patients with advanced gastric adenocarcinoma that progressed after first-line therapy. Although derived from an early-phase study, the observed response rates and depth of tumor shrinkage exceed those reported in historical studies of standard second-line regimens, including ramucirumab plus paclitaxel evaluated in the global RAINBOW trial (NCT01170663) and the RAINBOW-Asia study (NCT01939899), supporting continued clinical development of this HCB101-based combination.
Second-line gastric cancer represents a globally accepted and operationally well-defined SoC setting, yet clinical outcomes remain limited. HCB101 was engineered to complement, rather than disrupt, this established treatment scheme by enabling innate immune engagement while preserving standard dosing schedules, safety expectations, and routine clinical workflows.

Presentation Details
Poster Title:Dose-Dependent Antitumor Activity of HCB101 Plus Ramucirumab and Paclitaxel in Previously Treated Gastric Cancer
Abstract ID:372
Presenter:Dr.Alvin Luk
Date/Time:January 8, 2026 | 11:30a.m.–1:00p.m. PDT
Additional clinical data and analyses from the ongoing Phase Ib/IIa study will be presented during the ASCO-GI 2026 poster session.
“For many years, the biology of the CD47–SIRPα axis in immune evasion has been well understood, but translating that biology into clinical therapies has been challenging,” said Scott Liu, PhD, Founder, Chairman, and CEO of HanchorBio. “HCB101 was engineered from the outset using AI technologies to solve that problem. Specifically, an engineered SIRPα was designed with markedly enhanced binding affinity for CD47 on tumor cells, while avoiding the hematologic toxicities that limited earlier approaches. Dose-dependent anti-tumor activity was repeatedly observed when HCB101 was combined with the validated, commercially established SoC therapy for 2L GC. This observation provides a clear clinical illustration of how modulation of innate immunity can serve as a foundational, combination-ready immunotherapy backbone.”
Backbone-Centric Mechanistic Rationale
HCB101 is an engineered SIRPα–Fc fusion protein that selectively blocks the CD47–SIRPα innate immune checkpoint, thereby restoring macrophage-mediated tumor clearance while minimizing red blood cell binding. This mechanism is well-suited for combination with existing therapies. Ramucirumab, a cornerstone of second-line gastric cancer treatment, promotes vascular normalization and reduces VEGF-driven immunosuppression, whereas paclitaxel induces immunogenic tumor cell death and antigen release. Together, this regimen integrates innate immune activation into a validated standard-of-care therapy, providing a biologically coherent and clinically practical framework for the antitumor activity observed in 2L gastric cancer.
Alvin Luk, PhD, MBA, CCRA, President & Chief Medical Officer (Group) and Chief Executive Officer (U.S.A.) of HanchorBio, added, “Second-line gastric cancer has well-defined clinical benchmarks and treatment regimens that are widely used in routine practice. What stands out in these early data is not only the depth and frequency of tumor responses observed with HCB101 plus ramucirumab and paclitaxel, but also the ability to achieve this activity without compromising the safety profile or real-world deliverability of standard treatment. I look forward to presenting these data at ASCO-GI and discussing their broader implications for the role of innate immune engagement across gastric cancer treatment settings, informed by the strong signals we are observing in second-line disease.”
About HCB101
HCB101 is a rationally engineered SIRPα–IgG4 Fc fusion protein developed on HanchorBio’s FBDB™ platform to selectively block the CD47–SIRPα innate immune checkpoint while minimizing hematologic toxicity. Unlike earlier anti-CD47 approaches, HCB101 is designed to preserve macrophage-mediated antitumor activity while minimizing red blood cell and platelet binding, which historically limited clinical utility.
Importantly, HCB101 was engineered for compatibility with combinations. Its safety profile, receptor occupancy, and pharmacologic characteristics support seamless integration with established oncology regimens, enabling innate immune engagement without disrupting standard dosing, safety expectations, or clinical workflows. Across clinical and translational studies, HCB101 has demonstrated consistent target engagement and early antitumor activity as monotherapy and in combination, including in tumor settings historically considered challenging for CD47-directed therapies. Together, these attributes position HCB101 as a differentiated macrophage checkpoint backbone for macrophage checkpoint combination strategies across validated treatment frameworks in solid tumors and hematologic malignancies.
