Group 1 - The core viewpoint of the news is the collaboration between Baiaosaitu and Merck to evaluate antibody-conjugated lipid nanoparticles (Ab-LNP) for new applications in nucleic acid drug delivery, highlighting the strong interest in "precise delivery" in the biopharmaceutical sector [1][5] - The nucleic acid drug market is rapidly growing, with mRNA therapies gaining mainstream acceptance, but the delivery of nucleic acids remains a significant bottleneck [2][5] - The global lipid nanoparticle (LNP) market is projected to grow from $1.1 billion in 2025 to $3.5 billion by 2034, with a compound annual growth rate (CAGR) of 13.3% [2] Group 2 - Antibody-modified LNPs have shown promising results in animal models, significantly improving delivery efficiency to non-liver tissues, which is crucial for treating various diseases [2][3] - The partnership between Baiaosaitu and Merck marks the third deepening of their collaboration, indicating a new phase in the "antibody × delivery" model [4] - The trend towards platform and modular design in LNP technology is emerging, with new molecular forms like antibodies and bispecific antibodies expanding delivery capabilities [4] Group 3 - The investment landscape is shifting towards antibody-conjugated LNPs as a potential solution to the delivery bottleneck in nucleic acid drugs, with significant capital being directed into this area [3][5] - The collaboration between Baiaosaitu and Merck reflects the increasing involvement of Chinese biotech companies in the global restructuring of drug delivery technologies [5]

2025年9月，创新药研发平台型企业百奥赛图在过去一个月连续发布多项重要合作进展。无论是与跨国 巨头默克在抗体偶联脂质纳米颗粒（LNP）递送方案上的探索，还是与德国Tubulis的抗体许可协议，亦 或是合作伙伴IDEAYA在双抗ADC联合治疗的推进，都进一步印证了公司"双业务线"战略布局的前瞻性 与国际竞争力。 双业务线逻辑：模式动物+抗体平台 百奥赛图的发展战略核心在于"双业务线"： 与默克再度携手：探索抗体偶联LNP递送 9月初，百奥赛图宣布与默克（Merck）签署抗体选择权评估协议，围绕抗体偶联LNP递送展开合作。百 奥赛图将基于其RenMice®平台提供全人抗体，由默克评估其在LNP系统中的可行性。若默克选择行 权，百奥赛图将获得相应首付款、里程碑及分成收益。 这一合作不仅拓展了全人抗体在传统抗体药物之外的应用场景，也展示了抗体在核酸药物递送系统中潜 在的关键作用。业内人士认为，随着mRNA、siRNA等核酸疗法快速发展，精准递送已成为瓶颈，而抗 体偶联LNP有望提供更高效和更靶向的解决方案。 Tubulis行权：全人抗体进入ADC研发 紧随其后，9月中旬，百奥赛图宣布与德国新锐ADC企业Tubuli ...
