• Prestigious peer-review validates HCB101’s differentiated mechanism and translational strength.
• Clinical data show a nearly 90% partial response rate in 2L gastric cancer (combo) and safe escalation to 30 mg/kg (mono)

Excerpt from the Press Release:

TAIPEI, SHANGHAI and SAN FRANCISCO, Oct. 23, 2025 /PRNewswire/ — HanchorBio Inc. (TPEx: 7827), a global clinical-stage biotechnology company developing next-generation immunotherapies, today announced that its manuscript describing the discovery and preclinical development of HCB101, an engineered SIRPα-Fc fusion protein, has been published in the Journal of Hematology & Oncology (SCI Impact Factor 40.4; for reference, leading journals in the field of immuno-oncology include Journal of Clinical Oncology (impact factor 41.9), The Lancet Oncology (35.9), and Nature Cancer (28.5)).

The publication, titled “HCB101: A Novel Potent Ligand-Trap Fc-fusion Protein Targeting the CD47-SIRPα Pathway with High Safety and Preclinical Efficacy for Hematological and Solid Tumors,” describes the rational protein engineering that enabled HCB101 to restore macrophage-mediated phagocytosis and bridge innate and adaptive immune responses while reducing red blood cell binding. In preclinical studies, HCB101 showed broad activity across more than 80 xenograft and PDX tumor animal models with a safety profile that differs from first- and second-generation CD47-targeting agents.

Notably, a US competitor focusing on CD47/SIRPα published findings in JHO in November 2020, reporting on a third-generation anti-CD47–SIRPα therapy. This underscores the journal’s strong recognition within the field.
