成都，
2026年4月24日
全球领先的合同研究、开发与生产（CRDMO）服务公司药明生物（2269.HK）今日宣布，其位于成都的微生物商业化生产基地已顺利实现主体结构完工和关键设备到场。这一重要里程碑标志着公司正稳步推进该基地于2026年底实现GMP投产。
该微生物生产基地于去年6月在成都市温江区正式启动建设，规划面积约95000平方米，专注于生物药原液（DS）和制剂（DP）生产。
抗体偶联药物、细胞治疗、双/多抗、癌症疫苗等新一代疗法，会利用多肽、酶、抗体片段、纳米抗体及细胞因子等重组蛋白，而这些重组蛋白可依托微生物发酵技术，并结合相应的下游纯化与制剂工艺，实现规模化生产。随着新兴生物药分子类型的持续发展，微生物发酵技术正被越来越广泛地应用，其在产量、开发速度、规模化能力、工艺一致性及成本效率等方面的优势日益凸显。
药明生物微生物商业化生产基地将配备15000升发酵罐，原液年产能可达110批次，未来最大发酵规模可拓展至60000升。同时，该基地还将落地与维昇药业共建的中国首条双腔冻干制剂生产线，并配备西林瓶生产线，制剂年产能超过1000万支，进一步拓展其在复杂制剂商业化生产方面的能力。
值得一提的是，该基地在上下游生产环节全面引入自动化与数字化系统，支持稳定、可靠的GMP生产，提升合规性、运营效率与数据完整性。在基地设计过程中，ESG理念亦被系统性融入，通过海绵城市设计、光伏（PV）组件应用等绿色建筑实践，提升整体资源与能源利用效率。

WuXi Biologics Chengdu Microbial Commercial Manufacturing Site Achieves Structural Completion and Key Equipment Arrival
Chengdu,
April 24, 2026
WuXi Biologics (2269.HK), a leading global Contract Research, Development and Manufacturing Organization (CRDMO), today announced the structural completion and key equipment arrival at its microbial commercial manufacturing site in Chengdu, marking an important milestone as the company advances toward GMP release for production by the end of 2026.
The microbial manufacturing site, broke ground last June in Wenjiang District of Chengdu, spans approximately 95,000 square meters and is designed for commercial drug substance (DS) and drug product (DP) manufacturing of microbial-derived biologics. A broad spectrum of next-generation therapies, including ADCs, cell therapies, bi-/multi-specific antibodies, and cancer vaccines, leverage recombinant proteins such as polypeptides, enzymes, antibody fragments, nanobodies, and cytokines. These recombinant proteins can be manufactured at scale through microbial fermentation, supported by compatible downstream purification and formulation processes. Microbial fermentation is gaining broad adoption across emerging biologic modalities, driven by its advantages in yield, development speed, scalability, process consistency, and cost efficiency.
Upon completion, the manufacturing site will be equipped with a 15,000 L fermenter, enabling up to 110 DS batches annually, with long-term expansion potential up to 60,000 L. It will also feature China's first dual-chamber lyophilization production line, jointly established with VISEN Pharmaceuticals, along with a vial-filling line that offers commercial DP manufacturing capacity of more than 10 million vials per year, further enhancing its commercial manufacturing capabilities for complex formulations.
In addition, the manufacturing site incorporates integrated automation and digital systems across upstream and downstream operations to support reliable GMP manufacturing, strengthening compliance, operational efficiency, and data integrity. ESG concepts are also embedded into the site's design through green building practices such as sponge city design and the adoption of photovoltaic (PV) modules, enhancing overall resource and energy efficiency.
