In drug development, a methodical, multivariate approach is used to construct an effective process design based on assessing the risk associated with various steps. Design space is a scientific concept used in the pharmaceutical/biopharmaceutical industry to support and assure product quality. It allows manufacturers to explore combinations of multiple variables (CMAs and CPPs) using appropriate statistical tools. Among these, the guideline ICHQ8 explains that quality cannot be tested into products but should be built in by design. 2. Design Space The multidimensional combination and interaction of input variables(e.g., material attributes) and process parametersthat have been demonstrated to provide assurance of quality. Quality By Design Quality by Design (QbD) refers to the strategies developed and advanced by the US Food and Drug Administration, the International Conference on Harmonisation (ICH), and the United States Pharmacopeia (USP), 1-5 based on scientific principles and risk assessment and focused on product and process understanding. It allows manufacturers to explore combinations of multiple variables (CMAs and CPPs) using appropriate statistical tools. Number of times cited according to CrossRef: 3.
