The upcoming presentations will feature clinical data from the Company’s lead programs, including the HCB101-101 Phase 1 monotherapy (NCT05892718) and the HCB101-201 Phase 1b/2a combination (NCT06771622) studies, as well as the HCB301-101 Phase 1 monotherapy (NCT06487624) study, highlighting the therapeutic potential of its CD47-SIRPα innate immune backbone and multi-functional biologics:

HCB101: A highly engineered SIRPα–IgG4 Fc-fusion protein designed to maximize phagocytosis while minimizing hematologic toxicities.
HCB301: A first-in-class multi-specific candidate targeting the CD47/SIRPα, PD-1/PD-L1, and TGFb pathways to overcome the immunosuppressive tumor microenvironment (TME).
"The concentration of oral and poster presentations at premier global forums like AACR (Free AACR Whitepaper)-IO and ESMO (Free ESMO Whitepaper)-TAT reflects the significant momentum of our clinical programs," said Alvin Luk, PhD, MBA, CCRA, President & Chief Medical Officer (Group) and CEO (U.S.A.) of HanchorBio. "By presenting data on both HCB101 and HCB301, we are demonstrating our ability to execute our complex, multi-center trials and our commitment to delivering next-generation innate immune checkpoint therapies to patients globally."

About HCB101: A Next-Generation SIRPα Fc-Fusion Protein

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 reducing binding to red blood cells, a limitation that historically constrained the clinical utility of CD47-directed therapies.

HCB101 was engineered using AI-assisted structural modeling to achieve differentiated binding to CD47 on cancer cells while maintaining low affinity for CD47 on red blood cells. Its safety profile, receptor occupancy characteristics, and pharmacologic properties are designed to support integration with established oncology regimens without disrupting standard dosing, safety expectations, or clinical workflows. Across ongoing clinical and translational evaluation, HCB101 has demonstrated consistent target engagement and early antitumor activity as both monotherapy and in combination settings, including tumor types historically considered challenging for CD47-directed therapies.

Together, these attributes position HCB101 as a differentiated innate immune checkpoint backbone with broad potential for a wide variety of combination strategies across solid tumors and hematologic malignancies.

About HCB301: A Tri-Specific Checkpoint Immunotherapy

HCB301 is HanchorBio’s next-generation immunotherapy designed to integrate three synergistic mechanisms into a single molecule: CD47-SIRPα blockade to activate myeloid phagocytosis, PD-1 inhibition to restore exhausted T cells, and TGF-b pathway suppression to counteract immune evasion. Developed using the proprietary FBDB platform, HCB301 represents a next-generation approach to multi-checkpoint immunotherapy. Preclinical studies demonstrated enhanced immune activation and potent antitumor activity, and the results were presented at the SITC (Free SITC Whitepaper) 2025.
