PedCRIN tool for the biosamples management in pediatric clinical trials

In pediatric clinical research, it is essential to implement ethical and regulatory requirements, training, and facilities to grant the proper management of specimens, considering that blood sampling may be difficult, the number of specimens is usually limited, and all efforts should be made to minimize sample volumes. In the context of the Pediatric Clinical Research Infrastructure Network (PedCRIN) project, an easy-to-use tool has been developed to guide investigators and sponsors in managing specimens and associated data in compliance with the applicable European rules in the context of pediatric clinical trials. Key topics and research questions to properly manage biosamples and related data in the context of pediatric trials were identified by PedCRIN partners; the current European regulatory/ethical and legal resources were searched for and analyzed; the items/measures/procedures to ensure regulatory compliance of a pediatric trial with regards to biosamples were defined. A checklist of the key items to be considered for the management of biological samples in pediatric clinical trials in compliance with the European applicable rules and legislation, was prepared. It is publicly available on the PedCRIN website https://ecrin.org/projects/pedcrin. Five different topics were covered: consent and assent; minimizing harm and maximizing welfare; sampling volume; skills, training and facilities required for sampling; and long-term storage of biological material. This exercise addressed a specific need in the field of pediatric research to implement ad hoc procedures for specimen handling. In fact, specific guidance on the management of biosamples in pediatrics is not available.
