Batoclimab (HBM9161) is the first anti-FcRn monoclonal antibody completed Phase I to pivotal trials in China. As a novel, fully human anti-FcRn monoclonal antibody, batoclimab has the potential to be a breakthrough treatment option for a wide range of autoimmune diseases. In December 2023, the Company voluntarily planned to include additional long-term safety data and re-submitted the Biologic License Application (BLA) for batoclimab to the National Medical Products Administration of China (NMPA) in June 2024. In July 2024, NMPA accepted the BLA for batoclimab for the treatment of gMG. The Phase III pivotal clinical trial results of batoclimab were published in JAMA Neurology in March 2024, demonstrating sustained efficacy and safety with long-term use of batoclimab in the treatment of gMG.
HBM9378 is a fully human monoclonal antibody against thymic stromal lymphopoietin (TSLP) generated from the H2L2 Harbour Mice® platform. It binds to the TSLP ligand and inhibits the TSLP mediated signaling pathway by blocking the interaction between TSLP and TSLP receptor. TSLP is a well-validated cytokine that plays a key role in the development and progression of a wide array of immunological conditions, including asthma and chronic obstructive pulmonary disease (COPD), where its inhibition has demonstrated benefit in a wide array of inflammatory phenotypes. HBM9378 has been engineered to achieve an extended half-life and effector silencing and is subcutaneously administered.
- The Company received IND approval of HBM9378 for moderate-to-severe asthma from the NMPA in February 2022 and completed a Phase I clinical trial in healthy subjects in China. In November 2024, the Company submitted an IND application for HBM9378 for COPD to the NMPA, which was approved in January 2025.
- In January 2025, the Company and Kelun-Biotech entered into an exclusive license agreement with Windward Bio, under which Windward Bio was granted an exclusive license for the research, development, manufacturing and commercialization of HBM9378 globally (excluding Greater China and several Southeast and West Asian countries). In July 2025, Windward Bio initiated the global phase 2 POLARIS trial to evaluate the dosing, safety, and efficacy of HBM9378/WIN378 in patients with asthma. Initial data are expected in mid-2026.
Porustobart (HBM4003) is a next-generation, fully human heavy-chain-only anti-CTLA-4 antibody discovered and developed using the HCAb Harbour Mice® platform. It is also the first fully human heavy-chain-only antibody which entered clinical development globally. Compared with conventional CTLA-4 antibodies, porustobart has unique, favourable properties, including significant Treg cell depletion and optimized pharmacokinetics for improved safety. Additionally, by enhancing antibody-dependent cellular cytotoxicity (ADCC), porustobart increases the potential to selectively deplete intratumoral Treg cells, helping to overcome the efficacy and toxicity bottleneck of current CTLA-4 therapies. The Company has implemented a global development plan for multiple types of solid tumors with an adaptive treatment design for porustobart. Positive efficacy and safety data have been observed in the monotherapy trial targeting advanced solid tumors, as well as in combination trials with PD-1 inhibitors for melanoma, CRC, NEN and HCC. Final data from the study of HBM4003 in combination with toripalimab for advanced HCC were published in Clinical Cancer Research in August 2025. Data from the Phase II study of HBM4003 in combination with tislelizumab for the treatment of microsatellite stable (MSS) metastatic colorectal cancer will be presented at the ESMO Congress 2025.
HBM1020 is a first-in-class fully human monoclonal antibody generated from the H2L2 Harbour Mice® platform targeting B7H7. As a newly discovered member of the B7 family, B7H7 expression is found to be non-overlapping with PD-L1 expression in multiple tumor types, potentially playing a more significant role in tumor immune evasion. With its excellent product design and target features, HBM1020 presents great potential to address significant unmet medical needs for solid tumors. In September 2024, the Company presented the latest clinical data for patients with advanced solid tumors at the ESMO Congress 2024. The data demonstrated excellent safety and tolerability profiles for HBM1020. Of the 15 patients who received post-treatment tumor assessments, 7 patients (46.7%) achieved stable disease (SD), with two patients showing tumor shrinkage of 11% and 25%.
Key products in the next-generation innovation portfolio include:
HBM7004 is a novel B7H4xCD3 bispecific antibody. Using HBICE® bispecific technology and Harbour Mice® platform, this bispecific antibody was designed to provide innovative solutions for cancer immunotherapy from both efficacy and safety perspectives. The development of B7H4xCD3 bispecific HBICE® further consolidates the Company's bispecific immune cell engager platform, demonstrating the HBICE® platform's versatility and plug-and-play advantages. In preclinical studies, HBM7004 demonstrated an intratumor B7H4-dependent T cell activation manner. In multiple animal models, HBM7004 showed strong anti-tumor efficacy, remarkable in vivo stability, and reduced systemic toxicity. Additionally, in preclinical models, HBM7004 exhibited a strong synergistic effect when combined with a B7H4x4-1BB bispecific antibody at a low effector-to-target cell ratio, indicating an encouraging therapeutic window. The Company is currently conducting IND-enabling studies for HBM7004.
HBM7020 is a BCMAxCD3 bispecific antibody generated using the fully human HBICE® bispecific technology and Harbour Mice® platform. HBM7020 can crosslink targeted cells and T cells by binding to BCMA and CD3 on the cell surface, leading to potent T cell activation and cell elimination. By incorporating dual anti-BCMA binding sites for optimal cell targeting and monovalent-optimized CD3 activity to minimize CRS, HBM7020 demonstrated potent cytotoxicity with broad applications in both immunological and oncology diseases. In August 2023, HBM7020 obtained IND clearance from the NMPA to commence a Phase I trial for cancer in China. In 2024, the Company restructured its development strategy to target immunological diseases. In June 2025, Harbour BioMed entered global strategic collaboration with Otsuka. Under the terms of the agreement, Otsuka is granted an exclusive license to develop, manufacture, and commercialize HBM7020 globally, excluding Greater China (Mainland China, Hong Kong, Macau and Taiwan).
R2006 (CD19xCD3 bispecific antibody) and HBM7026 (BCMAxCD19xCD3 trispecific antibody) are two T-cell engagers (TCEs) in preclinical development. TCEs have emerged as an important therapeutic strategy for autoimmune diseases, as B-cell depletion has been shown to help restore immune system balance in multiple autoimmune conditions. TCEs can achieve deep depletion of B cells in peripheral blood, lymph nodes, and bone marrow, thereby resetting the immune system. Newly generated B cells subsequently return to a naïve and non-pathogenic state, potentially reducing inflammation and autoimmune responses. CD19 is a marker broadly expressed on precursor and mature B cells, while BCMA is highly expressed on mature B cells and plasma cells. Leveraging its fully human HCAb technology and optimized anti-CD3 antibodies, Harbour BioMed is developing TCEs with enhanced safety, reduced immunogenicity, and lower risk of cytokine release syndrome.
In March 2025, Harbour BioMed launched Élancé Therapeutics ("Élancé"). Harnessing Harbour BioMed's proprietary HCAb-based bispecific antibody technology, Élancé aims to develop innovative therapies addressing key challenges in current obesity treatment, including muscle preservation and long-term efficacy. Élancé is building a metabolic disease pipeline of multiple preclinical bispecific antibody programs.
