This decrease was primarily attributable to the combined impact of (i) optimized investments in our clinical programs and our molecule assets in discovery and pre-clinical stages; and (ii) the efficient implementation of cost control measures. Administrative expenses: The administrative expenses decreased by 28.6%, from US$27.3 million in 2022 to US$19.5 million in 2023. ROBUST PORTFOLIO AND DIFFERENTIATED PIPELINE Harbour Therapeutics, a sub-brand parallel to Nona Biosciences, is individually responsible for the development of the Company's product pipeline. Focused on oncology and immunology, Harbour Therapeutics has a robust and diversified pipeline of more than ten potentially differentiated drug candidates, four of which are in clinical development stage. Batoclimab (HBM9161), porustobart (HBM4003), HBM7008 and HBM1020 are the main products. Batoclimab, as the clinically most advanced FcRn inhibitor being developed in Greater China, has the potential to be a breakthrough treatment for a wide spectrum of autoimmune diseases in Greater China. Harbour Therapeutics completed the treatment of patients in early 2023 and announced the positive topline results of the phase III clinical trial of batoclimab for the treatment of generalized myasthenia gravis (gMG) in March, which is also the first positive pivotal trial outcome for batoclimab worldwide. This marks a major milestone as it is the Company's first product to complete phase III clinical trial and be poised for commercialization to benefit the gMG patients. The Company also initiated open-label extension clinical trial in 2022 and completed enrolment in March 2023. As the cut-off of open-label extension clinical trial for gMG in November 2023, the data showed sustainable efficacy and safety of batoclimab in long-term disease management. Porustobart (HBM4003) is the next-generation, fully human heavy chain only anti-CTLA-4 antibody generated from the HCAb platform. It is also the first fully human heavy chain only antibody which has entered into clinical development around the world. In 2023, Harbour Therapeutics conducted the global clinical development program of porustobart for multiple types of solid tumors, and positive data of efficacy and safety profile have been read out in the ongoing trials of neuroendocrine neoplasms and hepatocellular carcinoma. Another example demonstrating Harbour Therapeutics' strong research capabilities is the discovery of HBM7008, a novel product targeting B7H4 and 4-1BB. Developed from the immune cell engager platform HBICE®, HBM7008 is the only bispecific antibody against these two targets globally. Leveraging and integrating the expertise in biology and antibody engineering and the unique characteristics of HBICE® platform, HBM7008 showed exciting performance both in efficacy and safety profile at pre-clinical stage. In 2022, the Company conducted the phase I trials in the U.S. and Australia. In February 2023, to maintain a leading position in the development of this first-in-class asset, the Company entered into a co-development collaboration with Cullinan Oncology, to expand its study process in the U.S., Europe and Australia. HBM1020 is a first-in-class fully human monoclonal antibody generated from Harbour Mice® platform targeting B7H7. As a newly discovered member of the B7 family, B7H7 expression is found non-overlapping with PD-L1 expression in multiple tumor types, which potentially plays a more important role for tumor cells to escape immune surveillance. HBM1020 is the first product against B7H7 in clinical stage globally. With its excellent product design and target features, HBM1020 presents great potential to address huge unmet medical needs on solid tumors. Driven by the Company's leading drug innovation and discovery engine, new assets are continually being developed, of which HBM1020, HBM1022, HBM1007 and HBM9033 obtained the IND clearance from the U.S. FDA to initiate clinical study in the U.S. in 2023, and HBM9027 obtained the IND clearance from U.S. FDA in the first quarter of 2024. In addition, we have a number of pre-clinical stage products in the pipeline, including HBM7004, HBM1047 and HBM9014, which have shown great potential for development. PLATFORM-VALUE-MAXIMIZED BUSINESS COLLABORATIONS In 2023, the Company continued to expand its business collaborations with leading academic institutions and select industrial partners focusing on innovation and efficiency across the world. The business collaboration model is not only limited to out-licensing, but also to engage with academic institutions or other leading innovative pioneers in the industry for co-development and incubation of joint ventures on next-generation innovative therapy. With flexible business models built around proprietary technologies and platforms, the Company can and will maximize its platform value to address global unmet medical needs. Assets Collaboration of Harbour Therapeutics Harbour Therapeutics has entered into several external collaborations in terms of pipeline licensing and collaborations. In 2023, Harbour Therapeutics has granted the regional out-licensing of HBM7008 in the U.S. to Cullinan Oncology, and HBM7022/AZD5863, which was licensed to AstraZeneca in 2022, has entered into clinical stage. Meanwhile, the three assets which have been licensed the Greater China Rights to Hualan Genetic obtained IND approvals from NMPA to initiate clinical study in China. In addition, HBM9378, which was developed in collaboration with Kelun-Biotech, completed its phase I clinical trial. With these multiple collaborations based on the assets generated from HBICE®, Harbour Therapeutics has shown its strength and unique advantages in building a comprehensive portfolio in immune cell engagers. And the co-development and collaboration of the pipeline is not only the recognition of the industry partners for the Company's products and technology platforms, but will also help the Company to improve the efficiency of portfolio advancement, spread the costs and risks, and make the development of the Company more robust.
