Fresenius and WuXi Biologics enter exclusive development agreement to expand biosimilars pipeline

Fresenius SE & Co. KGaA announced that it has entered an exclusive development agreement with WuXi Biologics, a leading global contract organization for research, development and manufacturing. WuXi Biologics brings proven large-scale biologics development and manufacturing capability, a track record across monoclonal and bispecific antibodies and antibody-drug conjugates, and a worldwide network spanning Europe, the United States, China and Singapore. The agreement significantly expands and accelerates Fresenius' biosimilars pipeline while preserving strategic flexibility and disciplined capital allocation. It provides access to a scalable pathway to increase the portfolio from 29 marketed and pipeline molecules today to up to 66 molecules, addressing more than €370 billion in originator list-price-based-sales, extending Biopharma growth in the long term beyond its 2030 ambition. 

The agreement provides Fresenius with exclusive access to up to 37 identified biosimilar candidates over the next decade, making it the largest development agreement announced in the biosimilars industry to date. Development programs will be selected and advanced against Fresenius' established selection criteria, based on market attractiveness, development risk, and expected returns. Fresenius will hold exclusive global commercialization rights, including marketing authorizations, and the full economics of each commercialized product under the agreement.

Michael Sen, Chief Executive Officer of Fresenius, said: "We are doubling down on our Biopharma business. With this agreement, we are gaining access to development capabilities in a market where speed and scale are of the essence. It provides a disciplined, scalable way to potentially triple our portfolio while retaining economic ownership, strategic control and the flexibility to allocate capital to the most compelling opportunities. Combined with the full ownership of mAbxience, this fuels our Biopharma growth well beyond 2030."
