The company name 'Mosim' is an abbreviation of 'Modeling & Simulation'. Our core technology is the application of modeling and simulation to guide clinical drug development strategies and optimize the clinical study design. Drug development becomes increasingly expensive and time-consuming. Model-based drug development (MBDD) is a promising approach to improve decision making in drug development. Modeling and simulation provides a quantitative basis for the trial design, dose selection and clinical decision making at various stages of clinical development.
