Consequences of unlicenced and off label drug perscriptions: No dosing regimen No warning of possible adverse drug reactions No information about possible drug interactions No product liability for the drug by the sponsor No long term surveillance No adequate pediatric formulations
When we choose a drug for a child ... We rely on: - Personal experience (trial/error)? - Advice from colleagues/mentors? - Anecdotal reports in the literatur? - Extrapolation from adult data? - Small „trending“/inclusive trials?

Objectives of the EU-Regulation on Medicinal Products for Paediatric Use • To improve the health of the children of Europe, by: - increasing high quality research into medicines for them - promoting the development and authorization of such medicines - improving the information on medicines designed for children • While avoiding unnecessary studies in children and not delaying the authorization of medicines for adults
Key measures for patent medicines Requirement at the time of applications for new medicines for: • Data in children as agreed by PCor • A waiver from requirementor • A deferralof the timing of the studies
Key measures for patented medicines Rewards for studies conduced in children: - 6-months extension of the supplementory protectioncertificate (in-effect, a patent extension) - For orphan medicines, 2-years additional market exclusivity(10+2 years)
Key measures for off-patent medicines The Pediatric Use Marketing Authorisation (P.U.M.A.) : • enabeling 10-years data protection - use of existing brand name(brand recognition) - amended data requirements
Institutional or horizontal key measures of the EU-Regulation: • A new expert paediatric committe (PC) at the EMEA, which negotiates with the MAH the padiatric investigation plan (PIP) • Free scientific advice from EMEA • European network of experts • Information tools – inventory of therapeutic needs, new product labelling requirements, database of studies • Public funding for studies into off-patent medicines, e.g. accepted • application in the FP7 • Enhanced safety monitoring for marked products
Specific paediatric needs and priorities in Europe (particular for the neonates): • Analgesics • Sedatives • Immunomodulators, e.g. rheuma and TPL • Antiepileptic agents • Anticongestive and antiarrhythmic agents • Antihypertensive agents • Antiobstructive agents • Cytostatic agents Not included: Paed. anaesthesiology and child psychiatry
EMEA Priority-Listof Off-Patent Medicinal Products for Paediatric Studies in the FP7( http://www.emea.eu.int/pdfs/human/peg/49677706en.pdf )Methodology of Selection: • Severtity of the disease • Paediatric age groups affected (with special regard to the neonatal population) • Non-availability of treatment alternatives • High prevalence of the disease in the paediatric population • High level of evidence available and known or suspected efficacy or safety issues

Child Health in FPVII (2007-2013) 2nd call due June 07 and 3rd call due September 07Overarching topics on Child Health: • Adopting off-patent medicines to specific • needs of paediatric populations • Studies include the assessment of PK-data, efficacy, • safety and/or the development of age appropriate • formulation • Funding scheme: collaborative project with a • maximum of EC contribution of 3 000 000 € • for each (3 year) project ( 30 Mio € are available !)
