Advances in Large-Scale Biopharmaceutical Manufacturing
and Scale-Up Production*, 2nd Edition

    Post-Approval Changes for Large Scale Biopharmaceutical Manufacturing: Global

    Abstract

    Growing global demand for life saving products produced by large-scale biopharmaceutical manufacturing processes dictates that changes to the process, the facilities, the equipment, and/or the analytical controls used to produce them be expeditiously implemented without adverse impact on product quality. The implementation of significant post-approval manufacturing changes is governed by applicable government regulations that can vary dramatically from market to market. In today’s rapidly evolving regulatory environment, manufacturers of large-scale biopharmaceuticals face unprecedented global challenges in meeting post approval regulatory requirements and, at the same time, ensuring an uninterrupted supply of safe and efficacious product to the patient. Grounded in the concept of product comparability, this chapter shall endeavor to develop an understanding of the intricacies of the global post-approval regulatory environment. A series of case studies will be utilized to illustrate these complexities.
