WuXi Biologics Kicks off Construction of Microbial Manufacturing Site for Commercial Production in Chengdu

• The microbial manufacturing site in Chengdu will be equipped with a 15,000L fermenter, enabling the production of 80 to 110 drug substance (DS) batches annually with expansion potential to 60,000L.
• It will house China's first dual-chamber lyophilization production line and a vial filling line, with an overall drug product (DP) manufacturing capacity exceeding 10 million vials annually.
• The new site will feature WuXi Biologics' recently launched microbial expression platform EffiX^TM for the development and manufacturing of biologics with high yield, consistent quality, and superior stability and scalability.

CHENGDU, China, June 9, 2025 /PRNewswire/ -- WuXi Biologics (2269.HK), a leading global Contract Research, Development and Manufacturing Organization (CRDMO), today announced that it has kicked off construction of its new microbial manufacturing site for commercial production in the Wenjiang district of Chengdu, a renowned, vibrant hub for pharmaceutical development.

Spanning an area of 95,000 square meters, the new site is dedicated to a drug substance (DS) facility and a drug product (DP) facility for commercial manufacturing, encompassing a wide array of modalities, such as peptides,antibody fragments, plasmid DNA, enzymes, cytokines, and virus-like particles (VLPs). Scheduled to complete GMP release for production by the end of 2026, the site will be equipped with a 15,000L fermenter, enabling an annual production capacity of 80 to 110 DS batches. In the long run, capacity will be able to expand to 60,000L. Notably, the facility will house China's first dual-chamber lyophilization production line alongside a vial filling line, with overall DP manufacturing capacity exceeding 10 million vials annually, a significant enhancement of WuXi Biologics' commercial manufacturing capabilities for the global market.

The state-of-the-art facilities will feature WuXi Biologics' recently launched microbial expression platform EffiX^TM for the development and manufacturing of biologics with high yield, consistent quality, and superior stability and scalability, achieving titers that exceed 15 g/L for non-mAb recombinant proteins. Equipped with advanced automated systems to help ensure regulatory compliance, operational efficiency, and uncompromising quality, the facilities have also been designed with a strong focus on energy conservation and sustainability. Through the optimization of process development approaches and implementation of comprehensive carbon tracking mechanisms, the company aims to minimize its environmental footprint while maintaining high production standards.

WuXi Biologics will utilize the manufacturing site in Chengdu to produce VISEN Pharmaceuticals' inaugural commercial product, Lonapegsomatropin, a long-acting growth hormone for the treatment of pediatric growth hormone deficiency (PGHD). In addition to this landmark partnership, the company has also established strategic partnership with industry-leading biotech firm Virogen Biotechnology. These collaborations — centered around commercial manufacturing operations — underscore WuXi Biologics' expanding portfolio of partnerships and its drive to meet the growing demand for advanced biologic therapies. 

Dr. Chris Chen, CEO of WuXi Biologics, commented, "We are excited to kick off the construction of Chengdu microbial manufacturing site, a powerful enhancement to add to our comprehensive end-to-end microbial solutions. With the booming global market for microbial products presenting unprecedented potential for next-generation therapies, our Chengdu site — with its robust production scale and cutting-edge technologies — is ideally positioned to capitalize on this trend. The strategic partnerships with leading pharmaceutical companies not only validate the capabilities of our new site but also represent a pivotal milestone in our unwavering commitment to accelerating the development and delivery of innovative therapies to patients worldwide."
