End-to-end CRDMO

WuXi XDC offers end-to-end services – from discovery to commercial production in bioconjugation. The company’s services span from antibody intermediates and other biologics intermediates, chemical payloads and linkers, to bioconjugate drug substances and drug products. The comprehensive one-stop GMP manufacturing services for ADCs and other bioconjugates cover production at both the clinical and commercial stages, meeting the growing client demand across the globe. With integrated capabilities and efficiencies, WuXi XDC has significantly shortened the ADC development timeline – taking only 13-15 months from antibody DNA sequence to Investigational New Drug (IND) filing, nearly cutting in half the average industry timeline. In recognition of these capabilities, WuXi XDC has been named the winner of the “Best Contract Development Manufacturing Organization (CDMO)” prize at the 2023 World ADC Awards.

Global leading discovery and development platform

After a decade of solid growth, WuXi XDC has built an integrated technology and service platform that extends from discovery, development, manufacturing, and quality controls to regulatory filings for ADCs and other bioconjugates.

The platform provides clients with extensive expertise in state-of-the-art conjugation technologies, complex discovery, industry-leading process development, and comprehensive analytical methods, as well as dedicated and specialized facilities. As of June 2023, 110 on-going integrated projects are under development at WuXi XDC, including 47 post-IND bioconjugate projects, among which 16 projects are in phase II/III.
