The Paediatric Clinical Research Infrastructure Network (PedCRIN) is a four-year project launched on 1st January 2017. It brings together the European Clinical Research Infrastructure Network (ECRIN) and the founding partners of the European Paediatric Clinical Trial Research Infrastructure (EPCT-RI) to develop capacity for the management of multinational paediatric non-commercial clinical trials. PedCRIN will effectively bridge paediatricians and other partners across Europe (and internationally) to combine resources and expertise to conduct and manage robust studies, while minimising risk and protecting the child participants.
PedCRIN has received funding from the European Union’s Horizon 2020 programme, under grant agreement number 731046.
Lack of medicinal product testing on children: consequences
Many medicinal products have not been adequately tested on children or authorised for use on this population. The lack of paediatric drug testing has several consequences:
- Non-availability of appropriate paediatric formulations;
- Medicines used are often off-label and unlicensed;
- Children may receive ineffective treatment;
- Children may be given inaccurate dosing;
- Warnings of possible adverse drug reactions (ADRs) and adverse events are insufficient for medicinal products used in children;
- New and innovative medicines are available with a paediatric indication, but with no evidence of long-term benefit and risk, e.g. the biological agents.
Differences between children and adults
The paediatric population often responds to drugs and other therapeutics differently than adults do. Children differ from adults in anatomical and physiological ways and in the types of diseases from which they suffer; moreover, the manifestations of those diseases are different between children and adults. Children may respond differently to medicinal products, which have the potential to impact their growth and maturation and affect them psychosocially. It is also possible that a neonate may respond differently than older infants and children, and simply adjusting the dosage does not (always) solve the problem. Paediatric clinical trials are therefore essential to ensure that children receive appropriate, safe and effective treatment and care.
Clinical trials in children are more challenging than those in adults and the pool of eligible children for trials is often small. Children must have at least the same rights as adults regarding access to high quality and evidence-based medication and health care services.
Need for paediatric clinical trials
Paediatric clinical trials have novel complexities due to the safety concerns of testing medicines in children, ethical considerations, informed consent, lower prevalence of disease, the need to test different age groups, the possibility of late adverse effects, the requirement for tailored study design and the need for child-appropriate medicine formulations. To improve clinical care of children, more clinical trials are needed focussing on children's health with the goal of developing treatments, drugs, and devices specific to children. Paediatric clinical trials are necessary to test the efficacy of a medicinal product if it is:
- For diseases that affect children exclusively or have different symptoms and development in children;
- Intended to treat diseases occurring in adults and children for which there is currently no treatment;
- To treat a disease occurring in adults and children for which treatments exist, but where there is insufficient knowledge of efficacy or toxicity in children.
Non-commercial multinational trials
Commercially sponsored clinical trials are responsible for developing new medicines that can treat various disease areas. It is important to note, however, that these clinical trials only assess the activity of drugs that are chosen by a commercial entity that funds the entire process. Non-commercial or academic trials allow researchers to refine indications of available treatments and to optimise therapeutic strategies.
However, non-commercial trials face an increasing number of challenges, including a lack of funding, inadequate infrastructure to facilitate academic collaboration, and a lack of platform to discuss and solve issues related to academic trials.
