WuXi Biologics Successfully Completed
First FDA Routine GMP Inspection
WuXi Biologics is the first biologics company in
China approved by both the U.S. FDA and EMA

WuXi Biologics operates multiple state-of-the-art world-class drug product (DP) manufacturing facilities for the fill and finish of protein/antibody biotherapeutics and liquid or lyophilized parenterals. All of our facilities provide fully-automated final drug product formulation and filling under cGMP conditions as defined by the worldwide regulatory agencies including U.S. FDA, EMA and NMPA. We have also provided GMP drug product for clinical trials in other countries such as Japan, Korea, Singapore, Australia, Israel and India. To see details on each facility, click the corresponding links below:

Wuxi city (DP3)


Facility designed for the GMP manufacture of bioconjugate (e.g., Antibody Drug Conjugates (ADCs) Drug Substance and Drug Product. The site will feature an OEB5 Isolator for payload and linker weighing and dissolution and all product contact surfaces will utilize single-use systems to minimize risk throughout the manufacturing process. This facility was designed to handle OEB5 (or Safebridge III or IV) compounds used as payloads or toxins. The facilities meet U.S. FDA, EMA and NMPA GMP standards.

  • Fully-automated processing throughout formulation and filling process
  • Multiple validated container and closure configurations of 2R, 6R, 10R and 20R
  • Liquid filling up to 100,000 vials/batch/day (2R vial)
  • Lyophilized DP capacity up to 25,000 vials/batch/day (2R vial)

Also Available

  • Nitrogen blanketing
  • Light protected material handling from start of fill processing to final package steps
  • Liquid and lyo fills for Parenterals (e.g., small molecule and peptide therapeutics)


WuXi Biologics only utilizes the highest qualified containers, closures and raw materials provided by the world’s leading suppliers.

Wuxi City (DP4)

This state-of-the-art GMP manufacturing facility is equipped with the Vanrx Pharmasystems SA25 single-operator, fully-automated, robotic and gloveless isolator capable of filling an annual capacity of 5 million vials or Pre-Filled Syringes (PFS). This modular “workcell” approach greatly reduces risk due to its minimal human intervention and use of sterile, single-use disposable elements throughout the entire filling operation. This isolator is within a Grade C environment and can achieve as low as ISO 2 level particle counts. The facility has been GMP-ready since Q2 2019.

Features and Capabilities of the Vanrx SA25, gloveless isolator-based system at WuXi Biologics 

  • Filling Process: peristatic pump, single head (1 filling needle)
  • Utilizes Ready-to-Use (RTU) Containers Closure Systems (CCS)
  • Filling volume range: 1-100 mL
  • Container type: Vial and PFS (Cartridge fill & finish to be available in H2 2020)
  • Robotic filling processes reduce particle generation compared to conventional fill lines
  • Validated vial container and closure configurations: 2R, 6R, 8R, 10R
  • Validated PFS fill and finish: 0.5mL and 1.0mL Max speed: 30 units/min (PFS) and 25 units/min (vials)
  • Weight check: 100% or statistical IPC, either destructive or non-destructive
  • Automated and integrated EM and in-process control checks
  • Integrated stopper & cap system simplifying filling and providing greater quality assurance
  • Automated and integrated Electronic Batch Record system

Scalability of the Vanrx System

The Vanrx systems is compatible with the WuXi Biologics “scale-out” and “Dual Global Source” manufacturing paradigms. Future WuXi Biologics DP facilities will contain 2 – 6 units per facility. The small footprint and simplified qualification and validation plan allows for multiple systems to be used in the same facility and allows for faster capacity expansion.

Advantages of the Vanrx SA25 system

The Vanrx robotic, programmable and isolator-based systems offers significant advantages for multi-product facilities compared to conventional fill lines due to its inherent flexibility and ability to substantially reduce risk. To learn more about these advantages click here.
