Harbour BioMed's Innovative Approach Against Colorectal Cancer
Revolutionizing Colorectal Cancer Treatment with HBM4003
Harbour BioMed, a leader in the biopharmaceutical realm, focuses on creating advanced antibody therapeutics for immunology and oncology. At the upcoming ESMO Congress 2025, the company will showcase their promising Phase II clinical data on HBM4003, a unique anti-CTLA-4 antibody, combined with tislelizumab targeting microsatellite stable (MSS) metastatic colorectal cancer (mCRC).
Understanding the Challenge of MSS Metastatic Colorectal Cancer
This context of MSS mCRC poses significant treatment challenges due to its limited responsiveness to standard immune checkpoint inhibitors. Innovative approaches are necessary, and early research suggests that combining CTLA-4 blockade with PD-(L)1 inhibition could enhance therapeutic efficacy. In a recent multicenter Phase II study, a cohort of heavily pretreated patients suffering from non-liver metastatic MSS mCRC was analyzed, contributing to a deeper understanding of this condition.
Key Findings from the Phase II Study
Among the findings to be presented during the poster session at ESMO Congress 2025 are preliminary efficacy and safety results that hint at a promising direction for future treatment pathways. The study, identified by its reference number NCT05167071, outlines the methodology and group demographics, offering exciting insights into how HBM4003 could reshape patient outcomes.
Presentation Highlights
The poster presentation will provide several essential details:
Title: Efficacy and Safety of HBM4003, an Anti-CTLA-4 Antibody, Combined with Tislelizumab in MSS Metastatic Colorectal Cancer: A Multicenter, Phase II Study
Presentation Number: 807P
Speaker: Frank Zheng
This session aims to foster discussions among healthcare professionals to refine approaches as they explore innovative treatment options for mCRC patients.
About HBM4003
Porustobart (HBM4003) is heralded as a next-generation, fully human heavy-chain-only anti-CTLA-4 antibody. Its development utilized the proprietary HCAb Harbour Mice platform, which allows for creating fully human antibodies tailored for optimal efficacy. Comparing with traditional CTLA-4 antibodies, HBM4003 exhibits favorable attributes, such as enhanced Treg cell depletion and efficient pharmacokinetics, all aimed at improving patient safety and overall treatment success.
