Abstract: The SILICOFCM platform is an in-silico cloud computing platform which utilizes advanced computational workflows for drug development and optimized clinical therapy in the domain of hypertrophic cardiomyopathy (HCM). The current study presents the SILICOFCM's virtual population model (VPM) which can be used to generate high-quality virtual clinical data using both multivariate and machine learning methods along with virtual geometries for in-silico clinical trials. The proposed VPM workflow includes data quality management functionalities for outlier detection and similarity detection which are used to enhance the quality of the real patient data. In addition, the virtual clinical data generator which is part of the VPM includes both multivariate methods, such as, the multivariate normal distribution and machine learning methods, such as, the tree ensembles, the artificial neural networks, and the Bayesian networks. The VPM was utilized in a use-case scenario which included 592 records of patients with HCM towards the generation of clinical data for 1000 virtual patients. Our results suggest that the VPM was able to yield virtual distributions with an increased convergence with the real distributions, where the average goodness of fit was 0.038, the Kullback-Leibler (KL) divergence was 0.029 and the absolute correlation difference 0.0443 between the real and the virtual correlation matrices along with virtual geometries that mimic the real ones.
