The new article "Application of different approaches to generate virtual patient populations for the quantitative systems pharmacology model of erythropoiesis" by Galina Kolesova, Alexander Stepanov, Galina Lebedeva and Oleg Demin has been published in Journal of Pharmacokinetics and Pharmacodynamics.
Galina Kolesova comments on the article, "The traditional approach of QSP modeling includes fitting a model output to a series of mean data values. As a result, the parameters of the model represent fixed numbers enabling the description of mean data, thus we generated the so-called “reference patient”. However, the results of clinical trials include a description of variability in patients’ responses to a drug, which is typically expressed in terms of conventional statistical parameters such as standard deviations (SDs) from mean values. To allow a QSP model to reproduce the variability observed in response to a drug administration, a virtual patient (VP) population is usually generated and applied. In our study, we propose and compare four different approaches to generate virtual patient populations based on experimentally measured mean data and statistics, namely, (1) Monte Carlo Markov chain (MCMC), (2) model fitting to Monte Carlo samples, (3) population of clones, and (4) stochastically bounded selection. We applied these approaches to generate virtual patient populations in the QSP model of erythropoiesis. Our main task was to create a sample of virtual patients of the same size as that in clinical trials".
