Advancing a Robust and Differentiated Pipeline Harbour Therapeutics, a sub-brand parallel to Nona Biosciences, is now individually responsible for the development of the Company’s products pipeline. With a growing focus on immunology, inflammation and oncology, Harbour Therapeutics manages a highly differentiated portfolio that includes multiple innovative drug candidates in both clinical and Investigational New Drug (IND)/IND-enabling stages. In inflammation and immunology, the Company has built a robust preclinical pipeline encompassing bispecific and multi-specific antibodies generated using the HCAb-based Bispecific Immune Cell Antagonist (HBICATM) technology, as well as ultra long-acting biotherapeutics for immune-related diseases. In oncology, the Company is leveraging its HBICE® platform to develop bispecific and multi-specific antibodies with novel designs and differentiated mechanisms, such as HBM9027 (PD-L1xCD40) and HBM7004 (B7H4xCD3). In addition, the Company is utilizing its Harbour Mice® and XDC platforms to explore multiple therapeutic modalities, including HBM9033, a mesothelin-targeted ADC, and other ADC/RDC programs in early-stage development. Main products in the clinical stage include: 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 is a co-development project conducted by the Company and Kelun-Biotech, with both parties equally sharing the rights. HBM9378 has fully human sequences with a lower immunogenicity risk and better bioavailability compared to other TSLP-targeting competitors. Its long half-life optimization and outstanding biophysical properties support favourable dosing and formulation advantages. 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 chronic obstructive pulmonary disease (COPD) to the NMPA, which was approved in February 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). Currently, Windward Bio is preparing a global Phase II clinical trial for HBM9378. 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. 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%. Main products in IND and IND-enabling stages include: 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 and is currently preparing an IND application. HBM9027 is a novel PD-L1xCD40 bispecific antibody developed using the HBICE® bispecific antibody technology and Harbour Mice® platform. The development of PD-L1xCD40 bispecific antibody further expands the Company’s bispecific immune cell engager into the cutting-edge DC/myeloid cell engager field, showcasing the HBICE® platform’s versatile geometry formats and plug-and-play advantages. In January 2024, HBM9027 obtained IND approval from the Food and Drug Administration (FDA) to initiate a Phase I clinical trial in the U.S. 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. HBM9014 is a first-in-class, fully human antibody targeting leukemia inhibitory factor receptor (LIFR) for cancer treatment. It was discovered using the Harbour Mice® platform. HBM9014 blocks multiple IL-6 family cytokine pathways via LIFR to inhibit their function in promoting tumor progression, metastasis and chemoresistance. In preclinical studies, HBM9014 showed significant in vivo antitumor efficacy and enhanced efficacy in combination with cisplatin in multiple tumor models. In addition, HBM9014 exhibited strong tolerability in toxicology studies conducted on primates. In 2025, the Company will continue to actively explore drug development strategies and seek collaboration opportunities.
