Bioassay Method Development Services

Unveil biologics efficacy with target biologic insights

 

Bioassays play a crucial role in assessing the function, efficacy, and safety of biologic products, making their development a pivotal step in biologic product development. As an industry-leading provider of analytical solutions, WuXi Biologics offers a comprehensive suite of bioassay development services. Our deep understanding of mechanisms of action (MoA) and target biology across diverse and challenging modalities ensures precise and reliable results. With expertise in a wide range of techniques, rigorous study designs, and a strong grasp of regulatory requirements, we deliver high-quality bioassay methods.

 

Key features

Challenging Modalities

 

Challenging modalities require a comprehensive approach to bioassay development. WuXi Biologics starts with a rigorous study design to address structural complexity:

 

  • Product-specific risk assessment and mitigation plan
  • Assign control design
  • Product and method specificity
  • Product-related impurity research
  • Analytical characterization techniques

 

A broad range of flexible, multi-functional assays enable successful execution of the study design. Proprietary technologies and methods ensure the developed bioassay methods reveal efficacy and safety attributes that are otherwise invisible and represent the in vivo response.

Case study: reliable prediction of downstream outcomes

 

A case study of our bioassay method development service demonstrates strong utility in early-stage biologic product development. The data demonstrates a high correlation (r = 0.978) between the potency of a cell-based binding assay and the potency of a cytokine release functional assay across various treatment conditions. The high correlation suggests that the cell-based binding assay reliably predicts later-phase outcomes.
