Fresenius and WuXi Biologics agree development partnership covering up to 37 biosimilar candidates
Fresenius has entered an exclusive development agreement with WuXi Biologics covering options for up to 37 biosimilar candidates, potentially more than doubling its combined marketed and pipeline portfolio.
The agreement, announced on 2 November 2026, allows Fresenius to select biosimilar development programmes over the next decade while retaining exclusive global commercialisation rights and compensating WuXi Biologics through a fee-for-service development structure.
Initial targets include biosimilars referencing polatuzumab vedotin and teprotumumab, with the originator products across the potential portfolio representing more than €370 billion in aggregate sales rather than a disclosed transaction value.
