HanchorBio Presents Two Oral Presentations at ESMO TAT Asia 2026 Highlighting Progress Across Its Next-Generation Immunotherapy Pipeline<\/strong><\/h2>\n

Clinical data from HCB101 and first-in-human data from HCB301 support HanchorBio\u2019s strategy to develop<\/em><\/h3>\n

\u00a0multi-target immunotherapies addressing key mechanisms of tumor immune resistance<\/em><\/h3>\n

\u00a0<\/em>[Taipei, Shanghai, San Francisco<\/strong> | June 13, 2026<\/strong>] \u2013 HanchorBio, Inc. (TWSE: 7827), a global clinical-stage biotechnology company advancing next-generation immunotherapies for oncology and autoimmune diseases, today announced that two company-sponsored clinical programs were featured in oral presentations at the European Society for Medical Oncology Targeted Anticancer Therapies Asia Congress 2026, ESMO TAT Asia 2026, held in Hong Kong.<\/p>\n

\"\"<\/p>\n

The presentations highlighted clinical and translational progress for HCB101, HanchorBio\u2019s SIRP\u03b1-Fc innate checkpoint fusion protein targeting the CD47-SIRP\u03b1 axis, and HCB301, a tri-specific SIRP\u03b1-PD-L1-TGF-\u03b2 fusion protein designed to coordinate modulation of the SIRP\u03b1, PD-L1, and TGF-\u03b2 pathways in a single molecule.<\/p>\n

 <\/p>\n

In the HCB101 oral presentation, based on a May 2026 data cutoff, updated Phase 1a monotherapy data from HCB101-101 (NCT05892718) showed that 67 patients had been treated at doses ranging from 0.08 mg\/kg to 36 mg\/kg without reaching the maximum tolerated dose. Two dose-limiting toxicities of thrombocytopenia were observed, one Grade 3 at 2.56 mg\/kg and one Grade 4 at 36 mg\/kg, with no bleeding events reported. Treatment-related adverse events were predominantly Grade 1\u2013<\/strong>2, with one Grade 3 anemia event and no cumulative anemia or febrile neutropenia signal observed. HCB101 also demonstrated linear pharmacokinetics and sustained CD47 receptor occupancy of \u226590% at doses \u22658 mg\/kg. Preliminary antitumor activity was observed in this heavily pretreated population (median of 3 prior lines of treatment), including two confirmed partial responses: one in head and neck squamous cell carcinoma (with ~42% tumor reduction and ongoing response beyond 69 weeks), and one in marginal zone lymphoma (with ~89% metabolic reduction at Week 16). Eleven additional patients achieved durable stable disease across multiple tumor types.<\/p>\n

 <\/p>\n

The accepted HCB101 abstract also reported combination dose-escalation data from HCB101-201, a Phase 1b\/2 multi-cohort combination study (NCT06771622), including activity in second-line gastric cancer and first-line HER2-positive gastric cancer. In second-line gastric cancer, 15 efficacy-evaluable patients achieved an overall response rate of 60% across 2.56\u201312 mg\/kg, while the 5.12\u20138 mg\/kg mid-dose cohorts achieved an ORR of 80%, with maximal tumor regression of 78.2% and ongoing responses beyond 36 weeks. \u00a0In 1L HER2-positive gastric cancer, 5 efficacy-evaluable patients achieved an ORR of 80% (4\/5) and a disease control rate of 100%. Anti-tumor activity was also observed in additional Phase 1b\/2 cohorts, including PD-1-based combinations.<\/p>\n

 <\/p>\n

\u201cHaving two oral presentations at ESMO TAT Asia is an important recognition of the clinical progress we are making across our immune-modulation platform,\u201d said Scott Liu, PhD, Founder, Chairman, and CEO of HanchorBio<\/strong>.\u00a0 \u201cThe HCB101 data continue to support a differentiated therapeutic window for CD47-SIRP\u03b1 inhibition, while the first-in-human HCB301 data show that coordinated multi-pathway immune modulations can be translated into the clinic.\u201d<\/p>\n

 <\/p>\n

In the HCB301 oral presentation, first-in-human Phase 1 data supported the clinical feasibility of the tri-specific immune modulation across the SIRP\u03b1, PD-L1, and TGF-\u03b2 pathways. Among 21 patients enrolled across early dose levels, HCB301 demonstrated a manageable safety profile, predominantly low-grade and reversible hematologic events, and early disease stabilization in heavily pretreated patients with advanced solid tumors. These early data support continued dose escalation to further evaluate safety, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity.<\/p>\n

 <\/p>\n

\u201cTogether, these presentations highlight the progress of our clinical pipeline and the breadth of our immune-modulation strategy,\u201d said Alvin Luk, PhD, MBA, CCRA, President & Chief Medical Officer (Group) and CEO (U.S.A.) of HanchorBio<\/strong>. \u201cHCB101 provides clinical evidence supporting differentiated CD47\u2013SIRP\u03b1 inhibition, while HCB301 extends our approach into coordinated multi-pathway immune modulations. We believe these programs strategically and uniquely position HanchorBio to address a wide variety of tumors where innate and adaptive immune resistances, and suppressive tumor microenvironment all play important roles.\u201d<\/p>\n

 <\/p>\n

HanchorBio plans to continue advancing HCB101 across monotherapy and combination settings, with a focus on tumor types in which myeloid-driven immune suppression may contribute to treatment resistance. The Company\u2019s biology-based approach is supported by preclinical data across more than 80 tumor models in animals and emerging clinical data from HCB101. HCB301 will continue dose escalation to further evaluate safety, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity.<\/p>\n
