Summary (Overall) The Maternal and Pediatric Precision in Therapeutics (MPRINT) Hub will serve as a national resource for multi- disciplinary expertise and knowledge in maternal and pediatric therapeutics. The MPRINT Data, Model, Knowledge, and Research Coordination Center (DMKRCC) will support the MPRINT Centers of Excellence in Therapeutics (CET) and Steering Committee to coordinate and expand research relating to maternal and pediatric therapeutics. The DMKRCC will serve as the administrative component of the MPRINT Hub, coordinate outreach and dissemination of MPRINT Hub activities, and will serve as a conduit between the MPRINT Hub and the broader scientific community. Additionally, the MPRINT DMKRCC will organize annual MPRINT meetings and educational activities, including webinars, to cultivate translational research in maternal and pediatric therapeutics. The DMKRCC will identify, aggregate, and make available data, knowledge, and expertise in maternal and pediatric therapeutics to the wider research, drug development, and regulatory communities. Specifically, the DMKRCC will identify, evaluate, and collate pertinent data in a knowledgebase that will be made available through a web portal; utilize and enhance pharmacometric modeling approaches such as physiologically based pharmacokinetic and pharmacodynamic (PBPK/PD); support clinical trial design; and foster expertise in drug development and personalized therapy for maternal and pediatric populations. The specific aims of this proposal will develop a cohesive organizational structure to support the research of the MPRINT Hub as a whole as well as the individual cores within the DMKRCC. We will develop infrastructure to facilitate data sharing and knowledge dissemination, and work with the CETs and Steering Committee to identify and address changing needs of the maternal and pediatric communities.
