PQLI key topics - Criticality, design space, and control strategy

Abstract

This paper gives an overview of progress made by the ISPE PQLI initiative - a global industry-led initiative aimed at facilitating the implementation of ICH Q8, Q9, and ultimately Q10 guidance. Through this initiative ISPE is spearheading the effort to help industry begin to define areas where they will be able to provide the technical framework for the implementation of key elements of Quality by Design (QbD) - a systematic approach to development that begins with predefined objectives and emphasizes product and process understanding based on sound science and quality risk management. Three topic areas, Design Space, Criticality, and Control Strategy were selected for specific focus and discussion, and this paper gives an overview of progress in these three areas. © International Society for Pharmaceutical Engineering 2008.
