汉康生技宣布FDA C类会议
会议记录明确HCB101在
二线胃癌/胃食管交界处癌中
的开发路径
官方会议记录支持Phase 2导入期剂量/方案优化,随后开展以总生存期为主要终点的验证性研究,确立核心临床锚点适应症的开发方向
【台北、上海、旧金山|2026年7月1日】——汉康生技,一家致力于开发肿瘤及自身免疫疾病下一代免疫疗法的全球临床阶段生物技术公司,今日宣布已收到美国食品药品监督管理局关于HCB101在Phase 1后开发策略的C类会议正式会议记录。
该官方会议记录为HCB101在二线胃癌/胃食管交界处腺癌的FDA监管开发方向提供了清晰且可行的指导。汉康生技将二线胃癌/胃食管交界处癌视为该产品潜在注册路径的核心临床锚点。本次会议旨在显著降低HCB101在二线胃癌/胃食管交界处癌主要开发路径上的战略不确定性。基于FDA的反馈,公司计划在正在进行的Ib/IIa期HCB101-201多队列研究中,采用分阶段的联合剂量/方案探索策略,以支持候选方案的筛选,随后开展随机IIb期导入期研究,再进行验证性III期研究。
HCB101是汉康生技工程化的SIRPα-IgG4 Fc融合蛋白,旨在选择性阻断CD47–SIRPα“别吃我”信号,同时减少红细胞结合。该项目正被开发为一种髓系增强型免疫骨干疗法,用于合理的联合治疗,以二线胃癌/胃食管交界处癌作为主要开发重点。
FDA会议记录显示,监管机构未对汉康生技提出的将近期开发重点从单药RP2D申报转向每两周一次联合剂量/方案的前瞻性优化表示异议。会议记录还反映了FDA的反馈意见:继续与雷莫西尤单抗及紫杉醇进行联合剂量探索是合理的,且以总生存期为主要终点的验证性III期策略是该适应症合适的注册方向。
“FDA会议记录之所以重要,是因为它为HCB101在二线胃癌/胃食管交界处癌提供了清晰可行的监管方向,同时也强化了汉康生技更广泛的战略方向,”汉康生技创始人、董事长兼首席执行官刘世高博士表示。“我们将二线胃癌/胃食管交界处癌视为我们髓系增强剂平台的临床锚点——一个可以建立严谨开发路径、并为向其他髓系丰富肿瘤扩展奠定基础的适应症。我们相信这一结果支持明确的下一步:首先优化每两周一次给药剂量的方案,然后在具有全球标准治疗方案作为对照的临床明确环境中推进IIb期导入期研究,随后开展III期研究。长远来看,我们也相信这一平台可以从CD47–SIRPα生物学扩展至更广泛的多轴肿瘤微环境调控,并有望超越肿瘤领域,进入自身免疫、心血管及中枢神经系统疾病。”
在会议记录中,FDA表示公司在正在进行的Ib/IIa期HCB101-201多队列研究中提出的分阶段每两周一次联合方案探索在当前开发阶段似乎是合理的,但需提交完整方案并接受审评。会议记录还明确了未来二线胃癌/胃食管交界处癌注册路径的关键要素,包括:对于HER2阳性患者,需在获得当地批准且临床适用的情况下考虑既往使用德曲妥珠单抗治疗,任何例外情况需前瞻性记录;以及未来研究需在与美国患者相关的多区域框架内进行。此外,会议记录支持对研究人群中生物标志物定义的既往靶向治疗进行前瞻性处理,这与当前HER2阳性和CLDN18.2阳性疾病的治疗实践保持一致。
作为该优化策略的一部分,汉康生技计划不仅继续评估安全性、药代动力学、药效学和受体占有率,还将评估在雷莫西尤单抗及紫杉醇方案中的治疗可执行性,包括紫杉醇剂量调整的实际影响,这与FDA反馈意见一致。公司认为这对于在二线胃癌/胃食管交界处癌中进行严谨的方案筛选至关重要。
“我们相信二线胃癌/胃食管交界处癌是HCB101合适的核心开发适应症,因为它提供了一个临床定义明确的患者群体、一个全球确立的标准治疗方案、可解读的终点以及一条明确的注册路径,”汉康生技集团总裁兼首席医学官、美国子公司首席执行官陆英明博士补充道。“我们的目标一直是围绕最有助于决策的下一步来调整项目方向。FDA会议记录有助于明确路径,支持前瞻性的Phase 2导入期剂量/方案优化(联合雷莫西尤单抗及紫杉醇),随后开展验证性III期研究。结合HCB101在胃癌中获得的孤儿药资格认定,这为我们提供了一个更清晰的框架,以严谨且以注册为导向的方式执行该项目。”
汉康生技计划将FDA的反馈意见纳入HCB101的持续开发中,包括剂量/方案探索的方案优化、随机IIb期导入期剂量优化、安全性特征描述,以及用于未来临床研究申报的II/III期主方案统计框架。

HanchorBio Announces FDA Type C Meeting Minutes
Supporting a Clear Development Path for HCB101 in Second-Line Gastric/GEJ Cancer
Official minutes support Phase 2 lead-in dose/schedule optimization
followed by an OS-primary confirmatory strategy in HanchorBio’s lead clinical anchor indication
[Taipei, Shanghai, San Francisco | July 1, 2026] – HanchorBio, Inc. (TWSE: 7827), a global clinical-stage biotechnology company advancing next-generation immunotherapies for oncology and autoimmune diseases, today announced receipt of the official minutes from its recent U.S. Food and Drug Administration (FDA) Type C meeting regarding the post-Phase 1 development strategy for HCB101.
The official meeting minutes provide HanchorBio with a clear and workable FDA-facing development direction for HCB101 in second-line gastric/gastroesophageal junction (GC/GEJ) adenocarcinoma, which the Company views as the lead clinical anchor for potential registrational path for the program. The purpose of the meeting was to meaningfully reduce strategic uncertainty around HCB101’s lead development path in second-line GC/GEJ cancer. Based on the FDA feedback, the Company plans to proceed with a staged combination dose/schedule exploration strategy in the ongoing Phase 1b/2a HCB101-201 multi-cohort study (NCT06771622), intended to support the selection of candidate regimens for a randomized Phase 2b lead-in, followed by the confirmatory Phase 3 study.
HCB101 is HanchorBio’s engineered SIRPα-IgG4 Fc fusion protein designed to selectively block CD47–SIRPα “don’t eat me” signaling while reducing red-blood-cell binding. The program is being developed as a myeloid-enhancing immune backbone for rational combination therapy, with second-line GC/GEJ cancer as the lead development focus.
The FDA meeting minutes document that the Agency did not object to HanchorBio’s proposal to shift the near-term development focus away from a monotherapy RP2D declaration and toward a prospective optimization of the every-2-week (Q2W) combination dose/schedule. The minutes also reflect FDA’s feedback that continued combination dose exploration with ramucirumab and paclitaxel is appropriate, and that a confirmatory Phase 3 strategy (with OS as the primary endpoint) is the appropriate registrational direction in this setting.
“The FDA meeting minutes are important because they provide a clear and workable regulatory direction for HCB101 in second-line gastric/gastroesophageal junction cancer, while also reinforcing the broader strategic direction of HanchorBio,” said Scott Liu, PhD, Founder, Chairman, and CEO of HanchorBio. “We view second-line gastric/gastroesophageal junction cancer as the clinical anchor for our myeloid-enhancer platform — a setting where we can establish a disciplined development path and build the foundation for expansion into other myeloid-rich tumors. We believe this outcome supports a clear next step: optimize the dose for the Q2W schedule first, then advance to the Phase 2b lead-in followed by the Phase 3 study in a clinically defined setting with a comparator arm of the globally established standard-of-care regimen. Over time, we also believe this platform can extend beyond CD47–SIRPα biology into broader multi-axis tumor microenvironment modulation, and potentially beyond oncology into autoimmune, cardiovascular, and CNS diseases.”
In the meeting minutes, FDA indicated that the Company’s proposed staged Q2W combination regimen exploration in the ongoing Phase 1b/2a HCB101-201 multi-cohort study appears reasonable at the current stage of development, subject to full protocol submission and review. The minutes also clarify key elements of the future registrational path in second-line GC/GEJ cancer, including prior trastuzumab deruxtecan for HER2-positive patients, where locally approved and clinically appropriate, with any exceptions prospectively documented; and conduct of the future study in a multiregional framework relevant to U.S. patients. In addition, the minutes support prospective handling of biomarker-defined prior targeted therapy in the study population, aligned with current treatment practice for HER2-positive and CLDN18.2-positive disease.
As part of this optimization strategy, HanchorBio plans to continue evaluating not only safety, pharmacokinetics, pharmacodynamics, and receptor occupancy, but also treatment deliverability in the intended ramucirumab and paclitaxel regimen, including the practical impact of paclitaxel dose modification, consistent with the FDA feedback. The Company believes this is important for disciplined regimen selection in second-line GC/GEJ cancer.
“We believe second-line gastric/gastroesophageal junction cancer is the right lead development setting for HCB101 because it offers a clinically defined population, a globally established standard-of-care regimen, interpretable endpoints, and a focused registrational path,” added Alvin Luk, PhD, MBA, CCRA, President & Chief Medical Officer (Group) and CEO (U.S.A.) of HanchorBio. “Our objective has been to align the program around the most decision-useful next step. The FDA meeting minutes help clarify the path, supporting prospective Phase 2 lead-in dose/schedule optimization in combination with ramucirumab and paclitaxel, followed by a confirmatory Phase 3 study. Together with HCB101’s orphan drug designation in gastric cancer, this gives us a clearer framework to execute the program in a disciplined and registration-oriented manner.”
HanchorBio plans to incorporate the FDA’s feedback into the ongoing development of HCB101, including protocol refinement for dose/schedule exploration, the randomized Phase 2b lead-in dose optimization, safety characterization, and the Phase 2/3 master protocol statistical framework for future clinical study submissions.
