New partnership delivers clinically proven products and manufacturing processes for advanced therapies


SEATTLE   AGC Biologics, a leading global Biopharmaceutical Contract Development and Manufacturing Organization (CDMO), announced today a strategic partnership with RoosterBio Inc., a leading supplier of human mesenchymal stem/stromal cells (hMSCs), highly engineered media, and bioprocess development services.


The partnership creates an end-to-end solution for the development and production of hMSC and exosome therapeutics leveraging RoosterBio’s well-established cell and media products and process development services, coupled with AGC Biologics’ global cell and gene therapy manufacturing capabilities. 

 RoosterBio will utilize its extensive portfolio of cell and media products to develop robust, scalable processes for hMSC and exosome therapies.  These capabilities include genetic engineering of cells and exosomes to express therapeutic targets, upstream processing in both 2D flask and 3D bioreactor systems, downstream purification to achieve desired purity and potency, and comprehensive analytical characterization of the resulting formulated cell or exosome therapy. 

 AGC Biologics will utilize its global network to provide full Process Development, cGMP Manufacturing, Quality Control and Regulatory services for pre-clinical and phase I/II clinical trials, with the ability to scale to Phase III and commercial production. The CDMO also offers a range of development and manufacturing scales that can be tailored to the specific needs of drug developers in different regions worldwide. The AGC Biologics scientific teams have over two decades of experience in advanced therapy production and manufacturing, and have brought three commercial products to market. The global CDMO’s network of sites offers the latest cell therapy technologies and processes, including allogenic and autologous systems and techniques.

"AGC Biologics is happy to be partnering with RoosterBio. They have a reliable method for producing engineered cells and exosomes that can help developers create life-saving therapies," said Patricio Massera, Chief Executive Officer of AGC Biologics. "When you combine their work and expertise with AGC Biologics' scientific knowledge and global manufacturing services, it creates a comprehensive offering that can help these developers save time and money, and get their treatments in the hands of patients in need."
