Therapeutic orphans, off-label, pediatric drug development: towards reasonable pharmacotherapy for minors.

Abstract

Introduction: The concept that children are therapeutic orphans emerged in the 1960s, triggering eventually worldwide legislation to facilitate pediatric studies, called 'Pediatric Drug Development (PDD).' However, PDD's true aim is not better medicines for children but labels in minors; minors are not another species.

Areas covered: Absorption, distribution, metabolism, and excretion (ADME) differ in preterm newborns, but babies mature. With the exception of neonatology, the justifications for clinical, pharmacokinetic, and safety studies were and are exaggerated.

Expert opinion: PDD reflects an artificial regulatory challenge, reflecting mankind's transition into a world of effective new drugs compared to previous millennia when only materials taken from nature were available. Minors need dose assessment and proof of safety; there is a tendency to exaggerate the scope of pharmacokinetic and safety studies before and after the eighteenth birthday, potentially motivated not by industry's greed, but by researchers' desire for funding and regulatory authorities' desire for recognition, specifically as since 2007 the European Medicines Agency (EMA) augmented and expanded PDD: a new type of conflict of interest in medicines' administration and mainstream medical science.
