Catalent, Zumutor Collaborate
News Aug 05, 2016
Catalent Pharma Solutions and Zumutor Biologics Inc. have announced a successful research study, combining Catalent’s proprietary GPEx® technology and Zumutor’s fucose knockout platform, to create new and more efficacious antibodies. The GPEx technology platform creates stable, high-yielding mammalian cell lines for even the most difficult to express proteins. The advantages of applying GPEx technology span from early feasibility studies and clinical manufacturing, to commercial scale production.
Working in partnership, Catalent and Zumutor have created a fucose knockout GPEx cell line expressing high levels of an anti-HER2 antibody. The resulting modification completely removes fucose from the antibody, resulting in greatly enhanced Antibody Dependent Cellular Cytotoxicity (ADCC) without impacting production levels. The study was conducted in Zumutor’s research and development facility in Asia.
Kavitha Iyer, Chief Operating Officer of Zumutor, commented, “Zumutor’s fucose knockout technology enables us to create new and more efficacious antibodies. The inherent stability of GPEx cell lines makes these modifications possible and allows GPEx cell lines to be modified quickly, to produce a more potent antibody. Our partners have the potential to leverage this improved technology in therapeutic antibody product development, and generate a new regime of drug products engineered toward patient benefits.”
“GPEx technology was designed to offer our partners advantages over conventional cell line engineering systems, including increased flexibility and higher, more stable yields,” added Mike Riley, Vice President & General Manager of Catalent Biologics. “The use of GPEx technology, in combination with Zumutor’s afucosylation platform, has shown exciting results, and has the potential to be applied to other antibodies that could benefit from ADCC enhancement as part of their development programs.”

A Greener Way to Make KetonesNews
Researchers at McGill University have discovered a new, more environmentally friendly way to make ketones, an important chemical ingredient in pharmaceuticals. While ketones are found in a wide range of useful chemicals, they are commonly prepared through energy-intensive, multi-step technologies that create significant chemical waste.READ MORE
No Llamas RequiredNews
Detouring around a major research roadblock, researchers have found a new way to create valuable antibodies without needing … llamas? It is a little-known fact that llamas, alpacas, camels and other members of the camelid family make a unique class of antibodies that allow scientists to determine the structures of otherwise impossible-to-study proteins in the body, helping them to understand how those proteins malfunction in disease and how to design new drugs that act on them.READ MORE
