Repligen Announces Extension of Long Term Supply Agreement for Protein A

Repligen Corporation has announced that it has extended through 2019 a key long-term supply agreement with GE Healthcare for the manufacture of Protein A ligands at the Company’s facility in Lund, Sweden.

In extending this agreement, the Company aligned important manufacturing and supply terms with its existing GE Healthcare long-term supply agreement, which runs through 2021, for production out of the Company’s Waltham, MA facility. The combined agreements maintain Repligen as the main strategic supplier of recombinant and native forms of Protein A ligands to GE Healthcare.

Tony J. Hunt, President and Chief Executive Officer of Repligen said, “This agreement ensures the supply of high quality Protein A ligands to GE Healthcare. Our longtime collaboration is supported by Repligen’s business continuity plans, quality systems and access to our research and development team. We are proud of our Protein A manufacturing expertise and look forward to continuing this important relationship with GE Healthcare."

Protein A ligands are the critical component of Protein A chromatography media that bind and allow for the affinity purification of monoclonal antibodies. Protein A media is used in the manufacture of nearly all monoclonal antibody-based biologic drugs. Repligen is a leading supplier of Protein A affinity ligands, which the Company has manufactured for GE Healthcare for more than 15 years.

There are currently more than 50 monoclonal antibodies that have received regulatory approval and more than 300 are at various stages of clinical development. Worldwide revenues from this class of drug exceeded $85 billion in 2015.
