Core Viewpoint - The article highlights the significant advancements of Chinese innovative pharmaceutical companies, particularly in the dual antibody (dual-target) field, showcasing their ability to achieve breakthroughs on international academic stages amidst a global shift towards "true innovation and high barriers" in drug investment [1][2]. Group 1: Clinical Advancements - The anti-PD-L1/4-1BB dual antibody LBL-024 developed by Weili Zhibo has shown promising clinical data at the 2025 ASCO conference, transitioning from second-line monotherapy to first-line combination chemotherapy [2][4]. - LBL-024 demonstrated strong efficacy in treating patients with advanced neuroendocrine carcinoma (EP-NEC), with an overall response rate (ORR) of 75.0% and a disease control rate (DCR) of 92.3% in combination therapy [4][5]. - The drug's safety profile is favorable, with no dose-limiting toxicities reported and treatment-related adverse events primarily being mild to moderate [5]. Group 2: Market Potential - The global market for 4-1BB antibodies is projected to reach $1.32 billion by 2026, $2.9 billion by 2030, and $17.4 billion by 2035, with a compound annual growth rate (CAGR) of 285.1% from 2026 to 2030 [11]. - LBL-024's unique dual-target mechanism positions it as a potential first-in-class (FIC) drug, which could lead to higher pricing power and market penetration compared to traditional "me-too" drugs [11][15]. - The drug is being explored for multiple cancer types, including small cell lung cancer and ovarian cancer, expanding its commercial value and addressing unmet medical needs in large patient populations [8][9]. Group 3: Strategic Positioning - LBL-024's development reflects a shift from the traditional fast-follow model to a more innovative approach, establishing Chinese companies as leaders in original drug development rather than mere followers [6][15]. - The successful validation of LBL-024 not only enhances Weili Zhibo's competitive edge but also signifies the company's comprehensive capabilities in target selection, molecular design, and clinical development [15]. - The ongoing clinical trials for LBL-024 across various cancer types are expected to create a self-reinforcing growth cycle, extending its commercial lifecycle and enhancing its market presence [13].

论文展示了前沿生成式人工智能平台及其集成工作流程在快速开发ISM5939中的赋能,验证了人工智能在药 物发现中的潜力。 不同于直接STING激动剂,ISM5939通过靶向ENPP1精准调控肿瘤组织内的STING信号通路,恢复局部免疫 激活,从而增强抗肿瘤免疫反应。 首次证实ENPP1抑制剂能够克服对免疫检查点抑制剂和化疗的双重耐药性,为难治性肿瘤患者带来新的治疗 希望。 自2025年以来,这已是英矽智能第三篇以AI驱动药物研发实践为主题、发表在Nature子刊的研究成果。 免疫检查点抑制剂为肿瘤治疗带来范式变革,使得多种恶性肿瘤患者获益。然而,接受免疫检查点抑制剂治 疗的患者中仅有10%-35%可以获得显著持久的治疗效果,亟需创新治疗策略。 | Received: 28 August 2024 | Congying Pu16, Hui Cui15, Huaxing Yu15, Xin Cheng', Man Zhang', Luoheng Qin', | | --- | --- | | Accepted: 7 May 2025 | Zhilin Ning', Wen Zhang', Shan Chen', Y ...
Nature:华人团队开发新型PROTAC,治疗多种癌症类型,一作将回国加入南京大学
生物世界· 2025-05-27 03:57
Core Viewpoint - Immune checkpoint blockade (ICB) therapies, represented by anti-PD-1 and anti-PD-L1 monoclonal antibodies, have significantly transformed cancer treatment, yet many patients show poor response or develop resistance to these therapies [2][6]. Group 1: Research Findings - A study published in Nature by a team from the University of Michigan reveals that the balance between STAT5 and STAT3 shapes dendritic cell (DC) function and tumor immunity, leading to the development of a STAT3-targeting PROTAC that enhances tumor sensitivity to ICB therapy [3][10]. - The research indicates that the limited number and impaired function of dendritic cells in the tumor microenvironment (TME) hinder the effectiveness of ICB therapies, emphasizing the need to understand the mechanisms behind dendritic cell phenotype formation [6][8]. Group 2: Mechanisms of Action - STAT3 is often activated in the TME, mediating immune suppression and promoting tumor growth factors, while STAT5 is activated by cytokine signals and plays a positive role in anti-tumor immune responses [7][9]. - The study found that ICB therapy reprograms the interaction between STAT3 and STAT5 pathways in dendritic cells, activating T cell immunity and enhancing the efficacy of ICB [9][10]. Group 3: Therapeutic Implications - The development of STAT3 degradation agents, such as SD-36 and SD-2301, shows promise in reprogramming dendritic cells towards an immunogenic state, effectively treating advanced tumors and those resistant to ICB therapy without toxicity [9][10]. - This research opens new avenues for cancer immunotherapy by targeting the dynamic balance between STAT3 and STAT5 in dendritic cells [10].
