Expand Development of Bispecific and Multispecific Antibodies

As a leader in biologics discovery and development, experts at WuXi Biologics possess extensive experience in bispecific antibody (BsAb) and multispecific (MsAb) antibody development. Our innovative WuXiBody technology platform expands the field of bispecific and multispecific antibodies.

Based on novel engineering, the platform expedites the drug development process and significantly reduces production costs. WuXiBody enables the assembly of almost any monoclonal antibody (mAb) sequence pair into a BsAb or MsAb construct. Unique structural flexibility makes the platform convenient for building formats with different valency (for example, 2, 3, or 4 binding sites).

CMC Advantages

  • Saves 6 to 18 months of development time.
  • Reduces manufacturing costs by up to 90%.
  • Supports both fed-batch and concentrated fed-batch production.
  • Provides high protein expression in CHO cells
    • 5 g/L for fed-batch
    • 35 g/L for concentrated fed-batch
  • Eliminates aggregation issues.
  • Remains intact for more than 2 weeks in serum at 37 °C.
  • Exhibits no solubility limitations, maintaining concentrations greater than 30 mg/mL.

Engineering Advantages

  • Compatible with almost any mAb sequence
  • Available in both symmetric and asymmetric formats
  • Accommodates different bivalent, trivalent and tetravalent formats based on project needs and biology
  • Provides the same purification schemes as for mAbs
  • Ensures a long in vivo half-life
  • Expected to have low immunogenicity, using a natural human sequence without complicated engineering.
