Technologies & Platforms

WuXi Biologics greatly simplifies ADC drug development by providing a supply chain and all the necessary preclinical activities in one centralized region (all facilities are within 1-2 hours of each other).

We also provide world-class expertise in conjugation approaches and chemistry and scale-up and manufacture of payload, linker and antibody. In addition full analytical capabilities to characterize an ADC candidate and preclinical programs such as discovery biology, oncology, DMPK and toxicology are also available in-house. We offer a full range of development and manufacturing services both as an integrated package and standalone services. Our comprehensive solutions for ADCs include:

Case Study

In China for Global – 99.5% percent of ADC CMC and preclinical work for an ADC global IND conducted at WuXi

Antibody and payload Conjugation Development & Manufacture

We offer full suite of conjugation chemistry and capabilities  including:

  • Lysine/cysteine
  • Polysaccharide
  • Site-specific conjugation (ThioMab, non-natural amino acid, SmartTag, enzyme-assisted, etc.)
  • Milligram to hundreds of grams of ADC
  • Non-GMP and GMP production of ADC
  • Other biologics conjugation (PEGylation, HESylation, etc.)

Analytical development and characterization of ADCs

We leverage in-house expertise and state-of-the-art analytical equipments to characterize drug candidates at various stages of development, including UV/VIS, HPLC, cIEF, LC-MS. Our analytical assessment of ADCs encompasses all stages of their development, including drug-to-antibody ratio, protein concentration, aggregation, free drug content, PI, peptide mapping, ADC affinity and potency tests.
