Drug Substance Manufacturing

WuXi Biologics operates multiple world-class GMP manufacturing facilities for the production of biologics. Utilizing mammalian cell culture, we are able to produce a wide variety of biologics including monoclonal and bispecific antibodies, fusion proteins, antibody drug conjugates and other recombinant proteins. Over 90,000L of bioreactor capacity is available (150,000L by the close of 2021) for both clinical trials and commercial drug substance supply, increasing to 430,000L by 2023. Clinical and commercial scale drug product GMP manufacturing is also available.

Implementing next-generation facility designs for multi-product facilities, a “scale-out” single-use bioreactor production scheme and continuous bioprocessing technologies, WuXi Biologics has become a leading global biologics supplier for our partners and clients. The success of our GMP operations is also due to our “truly ONE” concept to commercialization drug development platform and excellence in project execution.

To support scale-up development efforts and large-scale process or batch record verification/qualification activities, both Wuxi and Shanghai maintain pilot/non-GMP manufacturing facilities. The manufacturing runs conducted at these sites also provide drug supply for IND-enabling toxicology studies or other preclinical and CMC development activities. The Shanghai Pilot Plant capacity is 6 x 200L and 1 x 500 L single-use/disposable bioreactors, and the Wuxi city Pilot Plant maintains 3 x 250L single-use/disposable bioreactors.

Each WuXi Biologics manufacturing facility shares the same quality system, and each site maintains dedicated in-house supporting functions such as QC testing labs, GMP warehouse, bio-waste and wastewater treatment, utilities (e.g., HVAC, WFI, Clean Steam, etc.), process automation systems (e.g., Delta V + OSI Pi Historian) and two independent power lines and back-up diesel generators.
