Cross-Pharma Collaboration for the Development of a Simulation Tool for the Model-Based Digital Design of Pharmaceutical Crystallization Processes (CrySiV)

Abstract: Precompetitive collaborations on new enabling technologies for research and development are becoming popular among pharmaceutical companies. The Enabling Technologies Consortium (ETC), a precompetitive collaboration of leading innovative pharmaceutical companies, identifies and executes projects, often with third-party collaborators, to develop new tools and technologies of mutual interest. Here, we report the results of one of the first ETC projects: the development of a user-friendly population balance model… Show more

“…13−15 A successful development of continuous crystallization requires additional understanding toward crystallization kinetics to ensure a robust process operation and overall economical optimality. 16,17 Mixed-suspension-mixed-product-removal (MSMPR) crystallization is a commonly used continuous concept that is analogous to a continuous stirred tank reactor. This concept has been widely used for purification and isolation of commodity chemicals and fine chemicals.…”

“…[7][8][9] In all the studies listed in Table 1, model inputs (independent variables) were assumed to be perfectly known during parameter estimation and all of the experimental uncertainty was assigned to the model outputs (dependent variables). This assumption enabled modelers to use either Least Squares (LS) 15,18,30 or Weighted Least Squares (WLS) estimation, 10,12,16,17,19,23,27,28,32,34 which is applied when there are multiple dependent variables with different levels of variability.…”

“…In 6 of the 11 studies where only a subset of the parameters was estimated, the authors decided which parameters should be fixed at nominal values and which should be estimated based on their scientific or engineering judgement. 13,16,26,29,32,33 The authors for the remaining 5 studies, used formal statistical methods for subset selection with sensitivity-based methods being most popular. 19,20,23,27,31 For example, Garcıa-Munoz et al and Sen et al used a popular orthogonalization-based algorithm to rank their model parameters from most estimable to least estimable.…”

“…In all the studies listed in Table 1, model inputs (independent variables) were assumed to be perfectly known during parameter estimation and all of the experimental uncertainty was assigned to the model outputs (dependent variables). This assumption enabled modelers to use either least squares (LS) 12,15,27 or weighted least squares (WLS) estimation, 7,9,13,14,16,20,24,25,29,31 which is applied when there are multiple dependent variables with different levels of variability. Sometimes, however, uncertainties in independent variables can be large due to measurement errors in process inputs or other difficulties in achieving the desired experimental settings.…”
