Pediatric Cardiovascular Drug Development and Research: Integration of Modeling and Simulation as One Future Direction

Abstract

The integration of the needs of children into the legal drug development process since 1997 in the United States and since 2007 in the European Union has improved health and stimulated innovative approaches in the design of clinical trials and will benefit both current and future populations. According to the US Food and Drug Administration, to date, 394 pediatric labels together with safer medicines and better dosing practices have provided a sound basis for the safer and more effective use of drugs in a pediatric population. This may be measurable with fewer medication errors and perhaps shorter hospital stays in the future. Although relevant data have been generated by clinical trials in pediatric populations, challenges, such as nonefficacy and safety issues, have arisen. Heterogeneity in the physiological maturation and growth processes and differences in the etiology and pathogenesis of disease in patients from birth to 18 years of age may explain these results. The use of cutting-edge technology, such as modeling and simulation of "in silico" pediatric populations, may allow the integration of data from previous trials and experiments into the design of future clinical trials and allow exploration in other areas that have the potential to enhance the outcome of clinical trials in children.
