Simulx is a powerful and flexible software designed for advanced clinical trial simulations, allowing users to build and simulate complex, user-designed scenarios. It combines an intuitive interface with high computational capabilities, providing quick answers to research questions and helping to identify optimal solutions in drug development. The application enables users to gain new insights through interactive exploration of dosing regimens and model parameters, offering real-time predictions. It facilitates the anticipation of clinical trial results via fast simulations of individual populations, significantly saving time by providing an efficient environment seamlessly interconnected with other tools like Monolix and PKanalix. Simulx allows users to focus on modeling and simulation rather than implementation details, thanks to its easy and flexible simulation setup and integrated post-processing tools. It supports a simple workflow for real-time analysis of treatment effects and model parameters on typical individuals, as well as simulating populations across different groups. The software also includes built-in tools for post-processing simulation outputs into outcomes and endpoints, along with statistical tests and uncertainty analysis for robust qualitative and quantitative comparisons between simulation groups.
