Commercial Process Development

CPD transforms clinical-stage processes into robust, scalable manufacturing workflows optimized for commercial readiness, regulatory alignment, and cost efficiency. Services include process optimization, scale-up, technology transfer, and raw material qualification.

Powered by our technology platforms—WuXiUI™ for fed-batch, WuXiUP™ for continuous bioprocessing—CPD delivers significant productivity and sustainability gains while reducing the cost of goods. With support for traditional fed-batch, intensified fed-batch, traditional perfusion, and other processing modes, we maximize flexibility.

Commercialization-Ready Performance

Exceptional Upstream Productivity

  • Achieve up to 9x higher drug substance productivity versus traditional fed-batch.
  • Reach fed-batch titers of 35 g/L in a 14-day culture.
  • Reduce costs by at least 40% with MagniCHO™ cell culture media.

Cost-Efficient Manufacturing by Design

  • Improve downstream yields by 10 to 15%.
  • Lower raw material usage by 20 to 60%.
  • Simplify operations, optimize cadence, and maximize facility use.
  • Reduce total manufacturing costs by 60 to 80%.

Reliable Speed and Scale

  • Complete CPD and optimization in 3 to 5 months.
  • Conduct drug substance process characterization in 4 to 8 months.
  • Integrate analytics with PAT and modeling technologies for deep product and process understanding.
  • Leverage global capacity for over 80 late-stage programs annually.

  • CE-based: Reduced and non-reduced CE-SDS, icIEF
  • Mass spectrometry: Intact, reduced, and deglycosylated mass, peptide mapping, disulfide bonds, sequence variants

Biological Assays

  • ELISA, enzyme activity, binding kinetics (BLI), neutralization, anti-proliferation, ADCC, ADCP, CDC, and more

Compendial and Biochemistry Assays

  • Appearance, pH, osmolality, extractable volume, visible and subvisible particles
  • Residual host cell protein (HCP), DNA, Protein A; Western blot; SDS-PAGE

BLA-Enabling Studies

Our BLA-enabling studies provide the critical product and process understanding that successful regulatory submission requires. The studies include resin and membrane reuse, viral clearance, impurity control, and comparability assessments.

Conducted at lab scale for cost-efficiency and speed, our resin and membrane lifetime studies establish safe reuse limits and generate used resins for BLA-enabling viral clearance. A structured 5-step workflow ensures consistency, quality, and regulatory readiness.

Highlights:

  • Custom scale-down model design
  • Cycle-stop criteria by unit operation
  • Full in-process analytics and logistics
  • Data insights across more than 50 resin and membrane types

WuXi Biologics delivers robust viral clearance studies to meet global regulatory expectations. Our BLA packages include viral inactivation, chromatography with mass balance, new and aged resin performance, and carryover assessments.

WuXi Biologics’ in-depth product characterization defines a drug product’s structure, function, and variability. This characterization supports safety, efficacy, and regulatory acceptance, enabling watertight process characterization.

Our comparability studies confirm product consistency before and after manufacturing changes through a structured, stepwise workflow that maintains quality, safety, and efficacy.

Highlights:

  • Completed over 40 BLA-enabling programs
  • Profiled variants in less than 2 months
  • Completed forced degradation in less than 3 months
  • Fractionalized size and charge variants at milligram scale
  • Leveraged high-resolution structural tools and biofunctional analysis

Our comparability studies combine in-depth product characterization with a structured, pre- to post-change workflow, ensuring consistent quality safety and efficacy after manufacturing changes.

WuXi Biologics conducts process-related impurity assessments aligned with ICH Q6B to ensure product quality and patient safety. Our highly specific, highly sensitive analytical methods establish impurity limits, support regulatory compliance, and safeguard product performance.

Highlights:

  • Address impurities from both cell culture and downstream purification
  • Apply advanced analytical methods for precise impurity qualification and quantification
  • Support acceptance criteria to meet global regulatory standards

Leveraging onsite laboratories, an exclusive HCP database, and liquid chromatography-mass spectrometry, WuXi Biologics delivers HCP detection services. These integrated capabilities support regulatory filings and product safety, and include:

  • ELISA kit development
  • Coverage assessment
  • Mass spectrometry profiling
  • Method development
  • Risk assessment
