title: Advances in the production and downstream processing of antibodies.
abstract: Sales of monoclonal antibody (mAbs) therapies exceeded $ 40 billion in 2010 and are expected to reach $ 70 billion by 2015. The majority of the approved antibodies are targeting cancer and autoimmune diseases with the top 5 grossing antibodies populating these two areas. In addition over 100 monoclonal antibodies are in Phase II and III of clinical development and numerous others are in various pre-clinical and safety studies. Commercial production of monoclonal antibodies is one of the few biotechnology manufacturing areas that has undergone significant improvements and standardization over the last ten years. Platform technologies have been established based on the structural similarities of these molecules and the regulatory requirements. These improvements include better cell lines, advent of high-performing media free of animal-derived components, and advances in bioreactor and purification processes. In this chapter we will examine the progress made in antibody production as well as discuss the future of manufacturing for these molecules, including the emergence of single use technologies.
