Pharmacokinetics, Pharmacodynamics, and Safety Profile of Understudied Drugs Administered to Children per Standard of Care / (POPS): NICHD-2019-POP02 (including COVID-19 drugs)

The majority of drugs administered to children are used off label, and PK studies to define appropriate dosing are lacking across pediatric age groups and special populations of children. Challenges associated with clinical trials in children limit the ability to conduct PK and dosing trials in this population. Studies capitalizing on standard-of-care procedures have proven successful in characterizing the PK of drugs used in children. The purpose of this study is to characterize the PK of understudied drugs administered to children per SOC as prescribed by their treating provider. This study will serve as a tool to better understand drug exposure in children receiving drugs per SOC. The data collected through this initiative will provide valuable PK and dosing information for drugs in different pediatric age groups as well as special populations of children, such as premature infants, critically ill children receiving ECMO or CRRT, children with Down syndrome and children with obesity, for which dosing may vary due to altered PK. In addition, the data collected in this study will serve as preliminary data to design and plan the best and most efficacious BPCA trials, proof-of-concept studies associated with biomarkers, and data to support applications for extramural funding. All of the drugs studied in this protocol are used as standard of care in children and are approved in adults. There will be multiple INDs held by the core study Principal Investigator: Danny Benjamin, MD, PhD (IND Sponsor) Kiser-Arena Distinguished Professor of Pediatrics, Duke University Faculty Associate Director, Duke Clinical Research Institute PO Box 17969 Durham NC 27715 Phone: 919-668-8295 Fax: 919-681-9457 danny.benjamin@duke.edu The Funding Sponsor is The National Institute of Child Health and Human Development (NICHD) NOTE: We will be participating in the COVID 19 arm of this study, which includes 6 drugs of interest (DOI). All other arms are on hold currently; and focus has been placed on the COVID 19 arm. However, in the future we may be interested in participating in other DOIs. The details of this arm of the study will be provided at the end of this document. (See Appendix P, pages 82-86 of main protocol)
