Medicines for children licensed by the European Medicines Agency (EMEA): the balance after 10 years

Information in summaries of product characteristics about use in children is limited and needs standardisation: a systematic analysis in Switzerland

BACKGROUND

A considerable proportion of drugs administered to children are not authorised for this purpose, and consequently off-label use is common in paediatric care. Our aims were to quantify systematically the number of drugs authorised in Switzerland for use in children based on their current summary of product characteristics (SmPC) and to assess the quality of this information.

METHODS

We used natural language processing to screen all Swiss SmPCs, available in German language in the open-source drug database, for information about use in children. Based on the SmPCs of the most frequently used drugs in Swiss children's hospitals, 10 search terms were defined to retrieve this information.

RESULTS

Of the analysed 4214 drugs corresponding to 1553 active substances, 2322 (55.1%) drugs were authorised for use in children. In only 639 (15.2%) SmPCs, information about authorisation for children was found in the section 'Therapeutic indications'. 320 (13.8%) SmPCs of drugs authorised for use in children contained only verbal age indications such as 'children' and 'adolescents' without a clear definition of the age or an age range.

CONCLUSIONS

Most Swiss SmPCs contain information about children, but only a minority refer to an official indication. Even if some SmPCs clearly indicate that use in children is authorised, a clear statement of the age at which the drug may be administered is missing. Standardisation of information about use in children in SmPCs is needed.

Development and performance of the c4c national clinical trial networks for optimizing pediatric trial facilitation

Introduction

The high failure rate of industry-driven pediatric clinical trials leads to insufficient timely labeling of drugs in children and a lack of scientific evidence, resulting in the persistently high off-label drug use. National clinical trial networks can facilitate collaboration between sites, investigators, and experts, increasing the likelihood of successful trials. Within the conect4children (c4c) network, an Innovative Medicines Initiative 2-funded project, National Hubs hosted by National Clinical Trials Networks were set up across 21 European countries to facilitate the setup and execution of pediatric clinical trials. In this paper, we aim to present the performance metrics of the trial feasibility process as well as learnings and challenges encountered by the Belgian and Dutch Networks in working within the European c4c project.

Method

The c4c National Hubs streamline pediatric clinical trials by initiating early country outreach, identifying overlapping studies, recommending quality trial sites, and supporting trial budgeting for both industry and academic settings. To show the impact of Pedmed-NL and Belgian Pediatric Clinical Research Network (BPCRN), internal metrics were collected from 2019 to 2022 on four industry-sponsored and three academic trials performed within the c4c network. Timelines and outcomes of the site identification were collected and analyzed for industry trials. A qualitative analysis was conducted through c4c platforms, sponsor interactions, and stakeholder engagement to evaluate the added value of a research network.

Results

In industry-sponsored trials, full feasibility questionnaires were completed within 2 weeks (n = 48), and inclusion rates were up to 80% of clinical sites. Before committing to c4c, 14% of sites were contacted by industry, leading to communication burdens. Utilizing national infrastructure knowledge and therapeutic environment insights helped optimize trial timelines and address feasibility challenges. In addition, national adaptations, such as bilingual staff and site development, played a role in streamlining trial operations in both academic and industry settings. Performance and experiences were similar for both networks.

Conclusion

The early-facilitation examples from the c4c trials demonstrated promising metrics for two National Hubs, including optimized start-up timelines and aiding site selection quality. The learnings and challenges of the Belgian and Dutch Networks provided insights for the development of clinical research networks.

Target therapy for high-risk neuroblastoma treatment: integration of regulatory and scientific tools is needed

Introduction

Several new active substances (ASs) targeting neuroblastoma (NBL) are under study. We aim to describe the developmental and regulatory status of a sample of ASs targeting NBL to underline the existing regulatory gaps in product development and to discuss possible improvements.

Methods

The developmental and regulatory statuses of the identified ASs targeting NBL were investigated by searching for preclinical studies, clinical trials (CTs), marketing authorizations, pediatric investigation plans (PIPs), waivers, orphan designations, and other regulatory procedures.

Results

A total of 188 ASs were identified. Of these, 55 were considered 'not under development' without preclinical or clinical studies. Preclinical studies were found for 115 ASs, of which 54 were associated with a medicinal product. A total of 283 CTs (as monotherapy or in combination) were identified for 70 ASs. Of these, 52% were at phases 1, 1/2, and 2 aimed at PK/PD/dosing activity. The remaining ones also included efficacy. Phase 3 studies were limited. Studies were completed for 14 ASs and suspended for 11. The highest rate of ASs involved in CTs was observed in the RAS-MAPK-MEK and VEGF groups. A total of 37 ASs were granted with a PIP, of which 14 involved NBL, 41 ASs with a waiver, and 18 ASs with both PIPs and waivers, with the PIP covering pediatric indications different from the adult ones. In almost all the PIPs, preclinical studies were required, together with early-phase CTs often including efficacy evaluation. Two PIPs were terminated because of negative study results, and eight PIPs are in progress. Variations in the SmPC were made for larotrectinib sulfate/Vitrakvi® and entrectinib/Rozlytrek® with the inclusion of a new indication. For both, the related PIPs are still ongoing. The orphan designation has been largely adopted, while PRIME designation has been less implemented.

Discussion

Several ASs entered early phase CTs but less than one out of four were included in a regulatory process, and only two were granted a pediatric indication extension. Our results confirm that it is necessary to identify a more efficient, less costly, and time-consuming "pediatric developmental model" integrating predictive preclinical study and innovative clinical study designs. Furthermore, stricter integration between scientific and regulatory efforts should be promoted.

Health technology assessment of paediatric medicines: European landscape, challenges and opportunities inside the conect4children project

The medicine development process is complex and requires time and effort to ensure safety, efficacy and quality. In paediatrics, this process is even more challenging, as it involves a subgroup of the population that already faces a considerable gap in the clinical evaluation of medicines and devices compared to the adult population. Moreover, access to therapies is heavily influenced by national health technology assessment (HTA) recommendations, which often form the basis for pricing and reimbursement decisions that affect the availability of effective treatments within the national health systems. Yet performing an HTA to assess the relative effectiveness and cost-effectiveness of a new children's treatment has several non-trivial implications, creating a critical issue for the paediatric population. In addition, the advent of innovative health technologies for children emphasises the need to empower the role of HTAs in paediatrics. This article aims at describing the most relevant elements of the drug development process in the paediatric field by focusing on the HTA. Particular attention will be paid to the factors that influence market access for new paediatric medicines and patients' access to treatment. The article will also highlight some central methodological challenges in conducting HTA in the paediatric field. Finally, the article will provide insight into how initiatives, such as conect4children, may subsequently reinforce HTA awareness in the paediatric community and strengthen collaborations through network mechanisms.

Catching Them Early: Framework Parameters and Progress for Prenatal and Childhood Application of Advanced Therapies

Advanced therapy medicinal products (ATMPs) are medicines for human use based on genes, cells or tissue engineering. After clear successes in adults, the nascent technology now sees increasing pediatric application. For many still untreatable disorders with pre- or perinatal onset, timely intervention is simply indispensable; thus, prenatal and pediatric applications of ATMPs hold great promise for curative treatments. Moreover, for most inherited disorders, early ATMP application may substantially improve efficiency, economy and accessibility compared with application in adults. Vindicating this notion, initial data for cell-based ATMPs show better cell yields, success rates and corrections of disease parameters for younger patients, in addition to reduced overall cell and vector requirements, illustrating that early application may resolve key obstacles to the widespread application of ATMPs for inherited disorders. Here, we provide a selective review of the latest ATMP developments for prenatal, perinatal and pediatric use, with special emphasis on its comparison with ATMPs for adults. Taken together, we provide a perspective on the enormous potential and key framework parameters of clinical prenatal and pediatric ATMP application.

Acute toxic exposures in children: analysis of a three year registry managed by a Pediatric poison control Center in Italy

Introduction

Acute pediatric poisoning is an emerging health and social problem. The aim of this study is to describe the characteristics of a large pediatric cohort exposed to xenobiotics, through the analysis of a Pediatric Poison Control Center (PPCc) registry.

Methods

This study, conducted in the Pediatric Hospital Bambino Gesù of Rome, a reference National Pediatric Hospital, collected data of children whose parents or caregivers contacted the PPCc by phone (group “P”), or who presented to the Emergency Department (group “ED”), during the three-year period 2014–2016. Data were prospectively and systematically collected in a pre-set electronic registry. Comparisons among age groups were performed and multivariable logistic regression models used to investigate associations with outcomes (hospital referral for “P”, and hospital admission for “ED”group).

Results

We collected data of 1611 children on group P and 1075 on group ED. Both groups were exposed to both pharmaceutical and non-pharmaceutical agents. Pharmaceutical agent exposure increased with age and the most common route of exposure was oral. Only 10% among P group were symptomatic children, with gastrointestinal symptoms. Among the ED patients, 30% were symptomatic children mostly with gastrointestinal (55.4%) and neurologic symptoms (23.8%). Intentional exposure (abuse substance and suicide attempt), which involved 7.7% of patients, was associated with older age and Hospital admission.

Conclusions

Our study describes the characteristics of xenobiotics exposures in different paediatric age groups, highlighting the impact of both pharmacological and intentional exposure. Furthermore, our study shows the utility of a specific PPCc, either through Phone support or by direct access to ED. PPCc phone counselling could avoid unnecessary access to the ED, a relevant achievement, particularly in the time of a pandemic.

Paediatric Medicines in Europe: The Paediatric Regulation-Is It Time for Reform?

Objectives: In this paper, we investigated the effects of the European Paediatric Regulation (EC) N° 1901/2006 with respect to satisfying the paediatric therapeutic needs, assessed in terms of the increased number of paediatric medicinal products, new therapeutic indications in specific high-need conditions (neonates, oncology, rare disease, etc.) and increased number of paediatric clinical studies supporting the marketing authorisation.

Methods: We analysed the paediatric medicinal products approved by the European Medicines Agency in the period January 2007-December 2019, by collecting the following data: year of approval, active substance, legal basis for the marketing authorisation, type of medicinal product (i.e., chemical, biological, or ATMP), orphan drug status, paediatric indication, Anatomical Therapeutic Chemical code (first-level), number and type of paediatric studies. Data were compared with similar data collected in the period 1996–2006.

Results: In the period January 1996–December 2019, in a total of 1,190 medicinal products and 843 active substances, 34 and 38%, respectively, were paediatric. In the two periods, before and after the Paediatric Regulation implementation, the paediatric/total medicinal products ratio was constant while the paediatric/total active substances ratio decreased. Moreover, excluding generics and biosimilars, a total of 106 and 175 paediatric medicines were granted a new paediatric indication, dosage or age group in the two periods; out of 175, 128 paediatric medicines had an approved Paediatric Investigational Plan. The remaining 47 were approved without an approved Paediatric Investigational Plan, following the provisions of Directive 2001/83/EC and repurposing an off-patent drug. The analysis of the clinical studies revealed that drugs with a Paediatric Investigational Plan were supported by 3.5 studies/drug while drugs without a Paediatric Investigational Plan were supported by only 1.6 studies/drug.

Discussion: This report confirms that the expectations of the European Paediatric Regulation (EC) N° 1901/2006 have been mainly satisfied. However, the reasons for the limited development of paediatric medicines in Europe, should be further discussed, taking advantage of recent initiatives in the regulatory field, such as the Action Plan on Paediatrics, and the open consultation on EU Pharmaceutical Strategy.

Drug Utilisation and Off-Label Use on a German Neonatal Intensive Care Unit: A Retrospective Cohort Study and 10-Year Comparison

Pharmacotherapy of neonates is complex and marked to a large extent of off-label use. The implementation of the Paediatric Regulation (2007) gave hope for a change in the safety and efficacy for drugs used in neonatal intensive care units (NICU). This study investigates drug utilisation patterns and off-label use in a German neonatal intensive care unit (NICU) in 2014. A 12-months retrospective, observational cohort study was performed at the NICU of the University Children's Hospital Erlangen, Germany. Licensing status was determined using the Summary of Product Characteristics (SmPC). Results are compared with a similar study conducted 10 years earlier. The study included 204 patients (57.8% male) (2004: 183) and 2274 drug prescriptions were recorded (2004: 1978). The drugs that were mostly prescribed were drugs for the nervous system (2004: 22.6%; 2014: 26.9%) and anti-infectives for systemic use (2004: 26.0%; 2014: 24.9%);34.3% (2004) and 39.2% (2014) of all prescriptions were off-label;62.7% of all patients received at least one off-label or unlicensed drug (2004: 70%). For 13 drugs, the licensing status changed either from off-label to label (n = 9) or vice versa (n = 4). Overall, there was no significant change neither in terms of the drugs used nor regarding their licensing status. Further studies are needed to validate these findings in a European context.

Pediatric prescribing in tertiary care teaching hospital of Delhi (India): fragmenting medicines for use

Lack of availability of age-appropriate dosage forms for children often results in use of adult dosage forms, which are administered to children after crushing or breaking. This can result in inappropriate doses being given to the children. This study was done to assess the prescribing pattern of use of medicines that had to be fragmented or crushed for use in relation to the age of the child. A prescription audit of 1200 outpatients and 400 inpatient records was done in the pediatric department of Lok Nayak tertiary care teaching hospital in the National Capital New Delhi, India. A structured pro forma was used for collecting the data. The total medicines prescribed, use of adult formulations, and number of adult medicines that had to be fragmented or broken for administration to pediatric patients were assessed. A total of 880 medicines were prescribed among inpatients and 2701 in outpatients. In inpatients, 230 (26.1%) medicines and in outpatients, 1013 (37.5%) medicines were fragmented before use. Some of these medicines were available in liquid oral dosage forms in Delhi Essential Medicine List (DEML) and should be available in the hospital. Medicines for use for common conditions were fragmented. Maximum use of fragmented medicines was in the age group of 6-9 years, both among inpatients and outpatients. Association of fragmentation with age was significant (p value < 0.05).Conclusion: Children are being prescribed dosage forms, requiring manual fragmentation or crushing. Policy changes and measures to make available age-appropriate pediatric dosage formulations need to be taken to improve pediatric pharmacotherapy in the hospital and health system. What is Known: • The dosage formulation prescribed to a patient can impact the patient's compliance with the therapy, accuracy of dosing, and patient and care providers' safety. • Lack of availability of age-appropriate dosage forms is common for children and often results in administration of adult dosage forms after crushing or breaking. What is New: • Some regularly prescribed medicines (14) including amoxicillin, albendazole, chloroquine, carbamazepine, valproate, and phenytoin that had to be fragmented were available in liquid oral dosage forms in the Delhi Essential Medicine List (DEML). • Despite being included in the EML, the patient has been denied access to appropriate medicines. It indicates a lack of concern and sensitivity about what is required for rational prescribing to children.

[Scientific impact and bibliometric contextualisation of Paediatrics compared to other specialities]

INTRODUCTION

The purpose of this paper is twofold. On the one hand, to identify and characterise the production, citation, impact and collaboration indicators of the Pediatrics area of the Journal Citation Reports, and on the other hand, to place the journal Anales de Pediatría in the context of the Spanish journals of another twenty areas and medical specialties.

MATERIAL AND METHOD

The sources of information used to obtain the indicators were Science Citation Index-Expanded, Journal Citation Reports, and Scimago Journal & Country Rank. A regression analysis was performed to determine the correlation between the citation and other variables.

RESULTS

Pediatrics ranked 8th in scientific production during the period 2009-2018. In citations per journal it ranks 17th, and the average citations per article approaches 27, occupying, in this case, the 18th position. Below Pediatrics are Emergency Medicine, Rehabilitation, and Primary Health Care. There are no citations for 12.47% of the articles. The average impact factor places the area in 18th place and its h index was 197, reaching 14th position, and standing above seven other areas. The percentage of works carried out with international collaboration was 17.71%, above Primary Health Care (12.88%), Oncology (16.37%), and Emergency Medicine (17.03%). Among the Spanish journals, Anales de Pediatría was the fourth most productive journal, and occupied an intermediate position in terms of the number of citations.

CONCLUSIONS

The indicators of citation and impact of the Pediatrics area tend to be above areas such as Emergency Medicine, Primary Health Care, Dentistry, Oral Surgery & Medicine, and Rehabilitation. Professional practice outside large hospitals, together with poor funding, as well as the low number of clinical trials due to the ethical requirements imposed on studies with children, may be the causes that result in moderate citation and impact indicators.

Clonidine in pediatric anesthesia: the new panacea or a drug still looking for an indication?

PURPOSE OF REVIEW

Clonidine, an α2-receptor agonist is a widely used drug in pediatrics with a large scope of indications ranging from prevention of postoperative emergence agitation, analgesia, anxiolysis, sedation, weaning to shivering. In the era of 'opioid-free' medicine with much attention be directed toward increasing problems with opioid use, clonidine due to its global availability, low cost and safety profile has become an even more interesting option.

RECENT FINDINGS

Increasing evidence from randomised clinical trials support the use of clonidine in healthy children in the perioperative setting. Clonidine appears to significantly reduce postoperative emergence agitation, opioid consumption, shivering, nausea and vomiting. In addition, emerging evidence support the use of clonidine for sedation of critically ill children in ICUs. In this review, the current evidence for clonidine in pediatrics is described and analyzed including a meta-analysis for prevention of emergence agitation.

SUMMARY

Clonidine appears a safe and beneficial drug with moderate to high-quality evidence supporting its use in pediatric anesthesia. However, for some indications and populations such as children younger than 12 months old and those with hemodynamic instability, there is an urgent need for high-quality trials.

Side effects associated with pharmacotherapy for pediatric irritable bowel syndrome and functional abdominal pain - not otherwise specified: a systematic review

INTRODUCTION

To systematically review the literature regarding the side effects of pharmacotherapy in children with irritable bowel syndrome (IBS) and functional abdominal pain - not otherwise specified (FAP-NOS). Areas covered: Cochrane Library, PubMed, and Embase databases were searched from inception to May 2018. The following inclusion criteria were applied: (1) randomized controlled trials (RCTs), cohort studies or case-control studies; (2) in children aged 4-18 years or adult studies if children are reported separately; (3) reporting a diagnosis of IBS or FAP-NOS as defined by the authors; and (4) reporting the occurrence of side effects of pharmacotherapy. Quality assessment of included studies was conducted. Expert opinion: A total of 4619 articles were identified; 17 were included. In 10/17 (59%) studies, side effects of pharmacotherapy (antispasmodics, antidepressants, antihistaminic agents, serotonergic agents and antibiotics) occurred. The majority of side effects were: (1) limited to the gastrointestinal tract and central nervous system and, 2) mild and transient. No serious adverse events were reported. This systematic review shows that data on safety in children with functional abdominal pain disorders are scarce, and highlights the lack of high-quality research for potential side effects of pediatric IBS and FAP-NOS. Further research by means of large well-designed-follow-up studies is necessary.

The Unlicensed and Off-label Prescription of Medications in General Paediatric Ward: An Observational Study

BACKGROUND

Unlicensed (UL) and Off-label (OL) prescription of medications is common in paediatrics and does not constitute negligent practice since there is often no approved alternative according to FDA bulary.

AIM

The study aimed to determine the current frequency of UL and OL prescriptions in children from one month to 12 years of age in a Paediatric Inpatient Unit (PIU).

METHODS

This is an observational, prospective study, reviewing the prescriptions of all patients admitted to the PIU in a university hospital in a single week in August 2014 and a single week in January 2015.

RESULTS

We included 157 patients of median age 18 months and median length of stay 24 days. There were 1,328 prescription items (average of 8.4 items/patient) and only two patients without UL/OL use. During the winter season (August), 27% of prescriptions were classified as UL and 44.6% as OL, and during summer (January), 29.6% as UL and 45.1% as OL. We identified 188 medications, of which the most prescribed were paracetamol (11%) and dipyrone (9.5%). The most frequent OL classification was regarding drug formulation (15.8%). In the winter week, the most frequent reasons for admission were respiratory (44%), followed by other clinical causes (CC) (17.3%), while in the summer week, they were CC (26.3%), followed by surgical and gastrohepatic (23.7%).

CONCLUSION

The OL prescription of medicines for children in Brazil is in accordance with the international literature. The higher prevalence of OL due to formulation found in this study is related to the use of formulations other than those used by the FDA.

Adverse Drug Reactions in Children: Pediatric Pharmacy and Drug Safety

An underappreciated problem in child health is the risk for adverse drug reactions (ADRs). While there is an impression that children are at a lower risk than adults for ADRs, in fact a number of factors germane to pediatric therapy place certain groups of children at a high risk for adverse events associated with therapy. Given the importance of drug safety, an understanding of a diagnostic classification for ADRs and of how to approach a possible ADR clinically are key skills for pediatric pharmacists. As drug therapy for children evolves, becomes more complex, and begins to use novel molecules and biologicals there will be an increasing need for pediatric pharmacists to be more involved in clinical care, education, and research specific to drug safety.

The CLOSED trial; CLOnidine compared with midazolam for SEDation of paediatric patients in the intensive care unit: study protocol for a multicentre randomised controlled trial

INTRODUCTION

Sedation is an essential part of paediatric critical care. Midazolam, often in combination with opioids, is the current gold standard drug. However, as it is a far-from-ideal agent, clonidine is increasingly being used in children. This drug is prescribed off-label for this indication, as many drugs in paediatrics are. Therefore, the CLOSED trial aims to provide data on the pharmacokinetics, safety and efficacy of clonidine for the sedation of mechanically ventilated patients in order to obtain a paediatric-use marketing authorisation.

METHODS AND ANALYSIS

The CLOSED study is a multicentre, double-blind, randomised, active-controlled non-inferiority trial with a 1:1 randomisation between clonidine and midazolam. Both treatment groups are stratified according to age in three groups with the same size: <28 days (n=100), 28 days to <2 years (n=100) and 2-18 years (n=100). The primary end point is defined as the occurrence of sedation failure within the study period. Secondary end points include a pharmacokinetic/pharmacodynamic relationship, pharmacogenetics, occurrence of delirium and withdrawal syndrome, opioid consumption and neurodevelopment in the neonatal age group. Logistic regression will be used for the primary end point, appropriate statistics will be used for the secondary end points.

ETHICS

Written informed consent will be obtained from the parents/caregivers. Verbal or deferred consent will be used in the sites where national legislation allows. The study has institutional review board approval at recruiting sites. The results will be published in a peer-reviewed journal and shared with the worldwide medical community.

Orphan medicinal products in Europe and United States to cover needs of patients with rare diseases: an increased common effort is to be foreseen

Background

In the European Union (EU) and United States (US), specific regulations have been released to provide incentives to develop and sell orphan medicinal products.

We analysed the status of orphan drugs designated that not yet received a marketing authorisation or already marketed for patients affected by rare diseases in the EU and US up to December 2015. For each drug, the following data were extracted: designation date, active substance(s), orphan condition and indication, trade name, approved therapeutic indication, approved ages, genetic nature of disease and if affects children.

Results

In the EU, 1264 Orphan Drug Designations have been granted and 133 medicinal products were approved covering a total of 179 indications and 122 rare conditions. Among these, 79 were approved under Regulation (EC)141/2000 (65 still listed in the Orphan Medicinal Products Register and 14 lost the orphan designation but still authorised) and 23 were approved centrally by the European Agency before the Orphan Regulation entered into force. On the other hand, in the US 3082 designations and 415 orphan products, covering a total of 521 indications and 300 rare conditions, were granted. As a result, the mean of designations per year is 79 in the EU and 93.4 in the US, while the mean of approved indications per year is 8.5 in the EU and 15.8 in the US.

No orphan product is marketed in the EU for bone and connective tissue, ophthalmic, poisoning/overdose, renal, urinary and reproductive rare diseases. Among the marketed medicinal products, only 46.6% in the EU and 35.2% in the US are approved for children.

If all the existing market approvals were merged, 362 additional therapeutic indications in the EU and 72 in the US would be covered.

Conclusions

Our data show that notwithstanding the incentives issued, the number of medicines for rare diseases is still limited, and this is more evident in certain therapeutic areas. However, by merging all the existing approvals, patients would benefit of substantial advantages in both geographic areas. Efforts and cooperation between EU and US seem the only way to speed up the development and marketing of drugs for rare diseases.

Harmonisation in study design and outcomes in paediatric antibiotic clinical trials: a systematic review

There is no global consensus on the conduct of clinical trials in children and neonates with complicated clinical infection syndromes. No comprehensive regulatory guidance exists for the design of antibiotic clinical trials in neonates and children. We did a systematic review of antibiotic clinical trials in complicated clinical infection syndromes (including bloodstream infections and community-acquired pneumonia) in children and neonates (0-18 years) to assess whether standardised European Medicines Agency (EMA) and US Food and Drug Administration (FDA) guidance for adults was used in paediatrics, and whether paediatric clinical trials applied consistent definitions for eligibility and outcomes. We searched MEDLINE, Cochrane CENTRAL databases, and ClinicalTrials.gov between Jan 1, 2000, and Nov 18, 2015. 82 individual studies met our inclusion criteria. The published studies reported on an average of 66% of CONSORT items. Study design, inclusion and exclusion criteria, and endpoints varied substantially across included studies. The comparison between paediatric clinical trials and adult EMA and FDA guidance highlighted that regulatory definitions are only variably applicable and used at present. Absence of consensus for paediatric antibiotic clinical trials is a major barrier to harmonisation in research and translation into clinical practice. To improve comparison of therapies and strategies, international collaboration among all relevant stakeholders leading to harmonised case definitions and outcome measures is needed.

Challenges in developing drugs for pediatric CNS disorders: A focus on psychopharmacology

Many psychiatric and behavioral disorders manifest in childhood (attention deficit hyperactivity disorder, obsessive compulsive disorder, anxiety, depression, schizophrenia, autism spectrum disorder, etc.) and the opportunity for intervening early may attenuate full development of the disorder and lessen long term disability. Yet, pediatric drug approvals for CNS indications are limited, and pediatric testing generally occurs only after establishing adult efficacy, more as an afterthought rather than with the initial goal of developing the medication for a pediatric CNS indication. With pharmaceutical companies decreasing funding of their neuroscience research divisions overall, the prospects for moving promising investigational drugs forward into pediatrics will only decline. The goal of this review is to highlight important challenges around pediatric drug development for psychiatric disorders, specifically during clinical development, and to present opportunities for filling these gaps, using new strategies for de-risking investigational drugs in new clinical trial designs/models. We will first present the current trends in pediatric drug efficacy testing in academic research and in industry trials, we will then discuss the regulatory landscape of pediatric drug testing, including policies intended to support and encourage more testing. Obstacles that remain will then be presented, followed by new designs, funding opportunities and considerations for testing investigational drugs safely.

Successful private-public funding of paediatric medicines research: lessons from the EU programme to fund research into off-patent medicines

The European Paediatric Regulation mandated the European Commission to fund research on off-patent medicines with demonstrated therapeutic interest for children. Responding to this mandate, five FP7 project calls were launched and 20 projects were granted. This paper aims to detail the funded projects and their preliminary results. Publicly available sources have been consulted and a descriptive analysis has been performed. Twenty Research Consortia including 246 partners in 29 European and non-European countries were created (involving 129 universities or public-funded research organisations, 51 private companies with 40 SMEs, 7 patient associations). The funded projects investigate 24 medicines, covering 10 therapeutic areas in all paediatric age groups. In response to the Paediatric Regulation and to apply for a Paediatric Use Marketing Authorisation, 15 Paediatric Investigation Plans have been granted by the EMA-Paediatric Committee, including 71 studies of whom 29 paediatric clinical trials, leading to a total of 7,300 children to be recruited in more than 380 investigational centres.

CONCLUSION

Notwithstanding the EU contribution for each study is lower than similar publicly funded projects, and also considering the complexity of paediatric research, these projects are performing high-quality research and are progressing towards the increase of new paediatric medicines on the market. Private-public partnerships have been effectively implemented, providing a good example for future collaborative actions. Since these projects cover a limited number of off-patent drugs and many unmet therapeutic needs in paediatrics remain, it is crucial foreseeing new similar initiatives in forthcoming European funding programmes.

Challenges for academic investigator-initiated pediatric trials for rare diseases

BACKGROUND

Clinical trials require great effort, time, expertise, and money. For clinicians at university hospitals with their full work load of teaching and medical care, the planning of an investigator-initiated clinical trial seems almost unthinkable. Despite their expertise in distinct diseases, university clinicians lack the time necessary to organize the funding and to initiate and conduct Phase III clinical trials in adults or in children.

OBJECTIVE

We sought to determine whether the difficulties faced by a clinician conducting a pediatric clinical trial can be overcome by passionate motivation and external support.

METHODS

Critical aspects of the application process of the world's first clinical trial in children with the rare hereditary kidney disease Alport syndrome treated with an angiotensin-converting enzyme inhibitor (Early Prospective Therapy Trial to Delay Renal Failure in Children With Alport Syndrome [EARLY PRO-TECT Alport]; http://www.clinicaltrials.gov NCT01485978; EudraCT 2010-024300-10) are described.

RESULTS

The following crucial factors enabled the investigator to complete this trial: (1) support through clinical trial, biometrician, and regulatory experts (Institute for Applied Research and Clinical Studies [IFS], Göttingen, Germany); (2) advice from the university's ethics committee (University Medicine Göttingen, Göttingen, Germany); (3) public funding (€1 million from the German Federal Ministry of Education and Research); (4) support from the respective medical society, aiming at the resolution of an important clinical problem (German Society of Pediatric Nephrology); and (5) support from the investigator's university as the official sponsor of the trial, providing long-term commitment and covering financial risks (University Medical Center Göttingen, Göttingen, Germany).

CONCLUSIONS

The study could pave the way for approval of ramipril as a drug to treat children with Alport syndrome. Even though the study might not result in label changes, the EARLY PRO-TECT Alport trial provides the basis of an educational campaign to sensitize physicians, especially pediatricians, general practitioners, and nephrologists, to pay special attention to the early detection of kidney diseases in children, which could improve medical care for all children with kidney diseases.

Trends in paediatric clinical pharmacology data in US pharmaceutical labelling

BACKGROUND

There is often a lack of safety and efficacy data in the paediatric population at the time of drug approval. Legislative efforts have promoted clinical pharmacology research in this underserved population. We sought to determine the quantity and quality of paediatric clinical pharmacology data in US drug labelling at the time of initial approval and to evaluate trends over time.

MATERIALS AND METHODS

The labelling data of 213 new molecular entities approved between 2003 and 2012 were systematically reviewed. The type of paediatric pharmacology data present at the time of approval was recorded and stratified by age group. Labelling revisions were analysed for updated paediatric data. The presence of paediatric-specific black-box warnings was noted.

RESULTS

Of the 213 drugs evaluated, 48 had adult-specific indications. Of the remaining 165 medicines, only 47 (28%) had paediatric study data at the time of initial labelling. The number of approved drugs with paediatric data was the greatest in 2005 (8, 44%) and was at its lowest point in 2012 (3, 11%). Only five medicines had neonatal data, with none of the anti-infective agents presenting neonatal information. Seven medications had a paediatric-specific black-box warning. Additional 16 medicines presented paediatric data during general labelling updates.

CONCLUSIONS

Despite efforts to improve the quality of paediatric clinical pharmacology data, there was not a significant increase in drugs with paediatric data at the time of approval over this 10-year study period. Paediatric drug approvals and labelling revisions continue to lag behind their adult counterparts.

The influence of the European paediatric regulation on marketing authorisation of orphan drugs for children

Background

Drug development for rare diseases is challenging, especially when these orphan drugs (OD) are intended for children. In 2007 the EU Paediatric Drug Regulation was enacted to improve the development of high quality and ethically researched medicines for children through the establishment of Paediatric Investigation Plans (PIPs). The effect of the EU Paediatric Drug Regulation on the marketing authorisation (MA) of drugs for children with rare diseases was studied.

Methods

Data on all designated orphan drugs, their indication, MA, PIPs and indication group (adult or child) were obtained from the European Medicines Agency (EMA). The outcome and duration of the process from orphan drug designation (ODD) to MA, was compared, per indication, by age group. The effect of the Paediatric Drug Regulation, implemented in 2007, on the application process was assessed with survival analysis.

Results

Eighty-one orphan drugs obtained MA since 2000 and half are authorised for (a subgroup of) children; another 34 are currently undergoing further investigations in children through agreed PIPs. The Paediatric Drug Regulation did not significantly increase the number of ODDs with potential paediatric indications (58% before vs 64% after 2007 of ODDs, p = 0.1) and did not lead to more MAs for ODs with paediatric indications (60% vs 43%, p = 0.22). ODs authorised after 2007 had a longer time to MA than those authorised before 2007 (Hazard ratio (95% CI) 2.80 (1.84-4.28), p < 0.001); potential paediatric use did not influence the time to MA (Hazard ratio (95% CI) 1.14 (0.77-1.70), p = 0.52).

Conclusions

The EU Paediatric Drug Regulation had a minor impact on development and availability of ODs for children, was associated with a longer time to MA, but ensured the further paediatric development of drugs still off-label to children. The impact of the Paediatric Drug Regulation on research quantity and quality in children through PIPs is not yet clear.

Pediatric drug formulations: a review of challenges and progress

Children differ from adults in many aspects of pharmacotherapy, including capabilities for drug administration, medicine-related toxicity, and taste preferences. It is essential that pediatric medicines are formulated to best suit a child's age, size, physiologic condition, and treatment requirements. To ensure adequate treatment of all children, different routes of administration, dosage forms, and strengths may be required. Many existing formulations are not suitable for children, which often leads to off-label and unlicensed use of adult medicines. New regulations, additional funding opportunities, and innovative collaborative research initiatives have resulted in some recent progress in the development of pediatric formulations. These advances include a paradigm shift toward oral solid formulations and a focus on novel preparations, including flexible, dispersible, and multiparticulate oral solid dosage forms. Such developments have enabled greater dose flexibility, easier administration, and better acceptance of drug formulations in children. However, new pediatric formulations address only a small part of all therapeutic needs in children; moreover, they are not always available. Five key issues need to be addressed to stimulate the further development of better medicines for children: (1) the continued prioritization of unmet formulation needs, particularly drug delivery in neonates and treatment gaps in pediatric cancers and childhood diseases in developing countries; (2) a better use of existing data to facilitate pediatric formulation development; (3) innovative technologies in adults that can be used to develop new pediatric formulations; (4) clinical feedback and practice-based evidence on the impact of novel formulations; and (5) improved access to new pediatric formulations.

Paediatric drug development: the impact of evolving regulations

Children deserve medicines that are adapted to their needs. The need to include children in drug development has been recognised increasingly over the past few decades. Legal and regulatory frameworks are well established in the EU and US. The amount of work done to study medicines for children is significantly greater than it was 10 years go. Proof-of-concept has been demonstrated for all segments of the paediatric drug development pipeline. It is now time to examine how the practice of developing medicines for children has evolved within those frameworks and to determine how that work should be generalised. This review describes the development of medicines for children and critically appraises the work that has been done within those frameworks. Significant effort is needed to realize the potential provided by the current regulatory framework. Using the work programme of the Global Research in Paediatrics (GRiP) Network of Excellence as a template we outline current work and future growing points.

Off-label prescribing for allergic diseases in children

The majority of drugs prescribed have not been tested in children and safety and efficacy of children's medicines are frequently supported by low quality of evidence. Therefore, a large percentage of prescriptions for children in the clinical daily practice are used off label. Despite the several recent legislation and regulatory efforts performed worldwide, they have not been successful in increasing availability of medicines adapted to children. Moreover, if we consider that 30% of the prescribed drugs for children are for the respiratory field and only 4% of new investigation projects for children research were proposed to access drugs for respiratory and allergy treatment, there is a clear imbalance of the children needs in this therapeutic area. This narrative review aimed to describe and discuss the off-label use of medicines in the treatment and control of respiratory and allergic diseases in children. It was recognized that a large percentage of prescriptions performed for allergy treatment in daily clinical practice are off label. The clinicians struggle on a daily basis with the responsibility to balance risk-benefits of an off-label prescription while involving the patients and their families in this decision. It is crucial to increase awareness of this reality not only for the clinician, but also to the global organizations and competent authorities. New measures for surveillance of off-label use should be established, namely through population databases implementation. There is a need for new proposal to correct the inconsistency between the priorities for pediatric drug research, frequently dependent on commercial motivations, in order to comply to the true needs of the children, especially on the respiratory and allergy fields.

Limited impact of EU paediatric regulation on Finnish clinical trials highlights need for Nordic collaboration

The Finnish Investigators Network for Paediatric Medicines (FINPEDMED) was established in 2007, to meet the expected increase in paediatric clinical trials following the new EU Paediatric Regulation. Between 2007 and 2012, FINPEDMED received 91 trial requests, 18 trials were started, and in 24 cases, Finnish investigators were not selected by sponsors.

CONCLUSION

This experience from Finland highlights the need for Nordic collaboration to increase expertise, recruitment base and attractiveness for sponsors.

Potential drug-drug interactions in pediatric outpatient prescriptions for newborns and infants

OBJECTIVES

To surveyed the quantities, types, and related information of potential drug-drug interactions (DDIs) and estimate the off-label use percentage of pediatric outpatient prescriptions for newborns and infants from the National Health Insurance Research Database (NHIRD) of Taiwan.

BACKGROUND

Adverse drug reactions (ADR) may cause morbidity and mortality, potential drug-drug interactions (DDI) increase the probability of ADR. Research on ADR and DDI in infants is of particular urgency and importance but the related profiles in these individuals are not well known.

METHODS

All prescriptions written by physicians in 2000 were analyzed to identify potential DDIs among drugs appearing on the same prescription sheet.

RESULTS

Of a total of 150.6 million prescription sheets, with 669.5 million prescriptions registered in the NHIRD of Taiwan, six million (3.99%) prescription sheets were for 2.1 million infants with 19.4 million (2.85%) prescriptions. There were 672,020 potential DDIs in this category, accounting for 3.53% per prescription; an estimated one DDI in every three patients. The interactions between aspirin and aluminum/magnesium hydroxide were most common (4.42%). Of the most significant drug-drug interactions, the interaction of digoxin with furosemide ranked first (20.14%), followed by the interactions of cisapride with furosemide and erythromycin (6.02% and 4.85%, respectively). The interactions of acetaminophen and anti-cholinergic agents comprised most types of drug-drug interactions (6.62%).

CONCLUSION

Although the prevalence rates of DDIs are low, life-threatening interactions may develop. Physicians must be reminded of the potential DDIs when prescribing medications for newborns and infants.

Off-label medicine use in children and adolescents: results of a population-based study in Germany

Background

Population-based self-reported data on off-label medicine use independent from health care provisions are lacking. The purpose of this study is to investigate off-label medicine use in children and adolescents in Germany in a non-clinical setting and to identify prevalence, determinants and spectrum of off-label medicine use.

Methods

Data were obtained from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) conducted by the Robert Koch Institute (2003–2006). 17,450 randomly selected children aged 0–17 years took part in the drug interviews. Of those, 8,899 took at least one medicine during the 7 days preceding the interview. Off-label medicine use was defined as the discrepancy between actual use and the intended use described in the summary of product characteristics. Off-label medicine use was stratified into off-label indication, off-label age, off-label over-dosing, and off-label under-dosing.

Results

The prevalence rate of off-label medicine use among those who used medicines amount of is 40.2%. The prevalence rate is significantly higher in boys (41.4%), in children aged 3 to 6 years (48.7%), without migration background (40.9%), with high social status (42.5%), living in small (42.0%) and medium sized cities (41.6%), and with a poor parents rated health status (41.7%). 12,667 preparations (attributable in respect to off-label use) were taken by 8,899 children. 30% of the medicines have been used off-label. Off-label medicine use was highest in preparations of the ATC-class “C00 Cardiovascular System”. In all origins of medicine, all age groups and all ATC-classes under-dosing was the most frequent reason for off-label medicine use.

Conclusions

There is a considerable level of self-reported off-label medicines use in the general paediatric population. Further investigations are needed to examine in how far off-label medicine use is based on lack of knowledge or on empiricism in paediatric pharmacotherapy. Attention also needs to be paid to under-dosing which potentially exposes drug users to risks of side effects without the benefit of a therapeutic effect. Clinical trials for licensing of paediatric medicines, education of health care professionals, but also of parents and carers are needed to ensure the rational use of medicines.

Development and stability assessment of liquid paediatric formulations containing sildenafil citrate

The purpose of this study is to develop and improve oral liquids formulations of sildenafil citrate for paediatric use. Four different formulations were developed, which are as follows: two aqueous solutions of sildenafil citrate (2.5 mg/mL), with or without preservatives, and two other solutions of sildenafil in simple syrup (1.25 mg/mL), with or without preservatives. All of the formulations were physically, chemically and microbiologically stable for three months. The results of the stability studies allowed for the optimisation of formulations without preservatives due to their simplicity and their similar stable conditions when compared to the formulations containing antimicrobials. The shelf life of both formulations was three months; however, upon opening, aqueous solutions should be used within 10 days and kept refrigerated, and syrup solutions should be used within 14 days in a hospital setting.

Frequency of the off-label use of antibiotics in clinical practice: a systematic review

Antibiotics constitute a major class among drugs commonly prescribed either empirically or for microbiologically documented infections in clinical practice. In addition, due to medical necessity physicians are forced, at times, to prescribe medications for off-label indications. The authors sought to record the frequency of the off-label use of antibiotics among both adult and pediatric patients. PubMed and Scopus databases were searched to identify relevant studies. A total of 25 studies met the inclusion criteria (725,124,505 prescriptions); 16 were prospective and nine retrospective. Fifteen studies reported on the pediatric population, seven on adults who had received a specific antibiotic, two on adult critical-care patients, and one on the general outpatient population. In the pediatric population, the percentage of off-label prescriptions varied from 1 to 94%. Off-label prescriptions varied from 19 to 43% in adult critical-care patients. Last, one study reporting on general outpatient care showed that 23% of prescriptions were off-label. Antibiotics are frequently prescribed as off-label among patient populations. The wide variation observed in the off-label use of antibiotics among pediatric patients might be attributed to the heterogeneity among the study populations regarding the age of children. Although this unapproved manner of prescribing cannot always be avoided, clinicians should only use unapproved drugs in cases when there are no effective alternatives are available and based on scientific evidence regarding safety and effectiveness.

Drug research and treatment for children in Canada: A challenge

Historically, children have been 'therapeutic orphans'. Many drugs have not been studied or labelled for use in children and adolescents, making the development and definition of optimally safe and effective drug therapies for the paediatric age group an ongoing challenge. Over the past decade, networks have developed in the United States and Europe to enhance drug research for this group, while no comparable evolution has occurred in Canada. The present statement provides context for the Canadian situation and makes recommendations that address two pressing needs: for more drug research focused on Canadian children and adolescents, including dedicated support for such research; and for increasing human capacity to undertake targeted studies. These initiatives should be undertaken collaboratively, nationally and internationally, and include strategic, innovative approaches to the unique problems and ethical issues posed by drug research in this population.

[Off-label approval of drug use in a tertiary hospital]

BACKGROUND AND OBJECTIVE

The Pharmacy and Therapeutics Committee (PTC) evaluates the requests for off-label uses with an abbreviated report format. The aim of this study is to perform a descriptive analysis of this activity and to study the rate of approvals.

MATERIAL AND METHODS

A descriptive study was performed on the PTC reports in a tertiary hospital between September 2009 and April 2011. The type of drug by treatment group and by type of dispensing, indication and requesting department was analysed. The final decision adopted was studied as the primary outcome, and the percentage of requests approved according to the characteristics of the drug evaluated, indication requested, alternatives used, evidence and cost, as secondary outcomes.

RESULTS

A total of 51 applications were analysed, of which 60.8% were drugs for hospital use and 54.9% cytostatic. The most requested indications were the onco-haematological (43.2%) and autoimmune (35.3%). Haematology was the department that made most requests (11 requests with 72.7% approved), Oncology and Paediatrics (both with 10 requests, with 50% approved). Almost two-thirds (60.8%) of the requests were approved. Of those that were not approved, 11 had not used up the therapeutic alternatives, and 8 had no evidence. Just under half (47.1%) of the drugs requested had a cost/patient between 10,000-100,000 euros,of which 58.3% were approved (cost per course of treatment if it had a defined period, or cost of treatment per year for chronic treatment).

CONCLUSION

There is an increase in the activity of the PTC that is growing over the years. Most applications focus on drugs for hospital use and cytostatic drugs by Onco-haematology. There is a high rate of approval by the PTC, and high variability in the percentage of approval depending on the department and the evidence of use. The difference between approved and unapproved requests followed a logic of cost-effectiveness.

The availability and age-appropriateness of medicines authorized for children in The Netherlands

AIM

To study the number of medicines and active chemical entities that are authorized and commercially available for children in the Netherlands and to evaluate the age-appropriateness of the available paediatric medicines.

METHODS

The availability of paediatric medicines and active chemical entities was studied with the help of a Dutch medicines database and the Summary of Product Characteristics. Medicines were categorized with respect to their route of administration, type of oral dosage form and therapeutic category. The age-appropriateness was assessed on three aspects: dose capability, suitability of the dosage form and inclusion of potentially harmful excipients.

RESULTS

Three thousand five hundred and forty-two paediatric medicines containing 703 different active chemical entities were identified. This equalled half of all the medicines and chemical entities available for human use. The percentage of paediatric medicines increased with age and varied for the route of administration from 22% (dermal) to 81% (inhalation) and for the therapeutic category from 11% (uro-genital, sex hormones) to 89% (anti-parasites). The appropriateness of the paediatric medicines with respect to their authorization status, dose capability and dosage form increased with age from 27-88%. Fifty-two percent of all oral paediatric liquid formulations contained a potentially harmful excipient.

CONCLUSION

This study confirms the limited availability of paediatric medicines for a broad range of therapeutic areas and shows that paediatric medicines may not be age-appropriate, even if authorized. While confirming the need for a legislative incentive, the results also provide baseline information for an estimation of the effect of the European Paediatric Regulation in the near future.

Paediatric drug use with focus on off-label prescriptions in Swedish outpatient care--a nationwide study

AIM

To determine drug prescription and proportion of off-label dispensing in the Swedish paediatric outpatient population.

METHODS

All dispensed outpatient prescriptions to children aged 0 < 18 years as well as the proportion of off-label drug use during 2007 were analysed using data from the Swedish Prescribed Drug Register.

RESULTS

In total, 2.19 million drug prescriptions of 898 different drug substances were dispensed to paediatric patients, and of those substances, 64% had been dispensed off-label at least once. The overall off-label rate of all prescriptions was 13.5%, among which topical drugs as well as sex hormones were the most commonly prescribed off-label drugs. More than half of all children in Sweden had received at least one prescribed drug in 2007.

CONCLUSIONS

There is a high prescribing of medicines to children in outpatient care in Sweden with a considerable amount of off-label prescriptions. Topically administered drugs, sex hormones, antidepressants, hypnotics, cardiovascular drugs and nonsteroidal anti-inflammatory drugs were commonly prescribed off-label.

Juvenile animal studies in the development of pediatric medicines: experience from European medicines and pediatric investigation plans

INTRODUCTION

The need for early consideration of pediatric investigation plans (PIP) to support an indication in pediatric population has led to an increased focus on the relevance of nonclinical studies in juvenile animals (JAS). The usefulness of JAS is not yet established and a criterion for request is still a learning process.

OBJECTIVE

This article compares data from JAS in all medicines approved by European centralized procedure before Pediatric Regulation (1995-2005) and data from JAS in the nonclinical information on all approved PIP (2007-2009).

RESULTS

Of the 226 substances licensed by centralized procedure in 10 years, 31.9% were considered for children and 31 JAS were described in 9.7%. Since 2007, of the 205 PIP decisions, 50 PIP (24.3%) have 87 JAS planned or requested. The mean number of JAS in each medicine or PIP, increased from 1.4 to 1.7 between the two periods and the juvenile rat remained as the prevalent species.

CONCLUSIONS

Results demonstrate that JAS planned/performed in EU environment has significantly increased.

Personalised medicine in paediatrics: individualising treatment in children with rare neurological diseases

The development of personalised medicine is of considerable importance for paediatric patient populations, and represents a move away from the use of treatment dosages based on experience with the same compounds in adults. Currently, however, we know little about developmental pharmacogenomics and, although many biomarkers are available for clinical research use, there have been few applications in the management of paediatric diseases. This paper reviews where we are in the journey towards achieving paediatric personalised medicine and describes a group of diseases requiring such an approach. The personalised medicine approach is particularly relevant for the treatment of rare childhood diseases, and the group of life-threatening neurological disorders known as lysosomal storage diseases represents a potential study population. The genetic bases of these disorders are generally well defined, there is the potential for diagnosis at birth or prenatally, and there are a range of therapeutic options available or under development.

Drug treatments in a neonatal setting: focus on the off-label use in the first month of life

OBJECTIVE

The purpose of this work was to analyse drugs prescribed in the first month of life among a group of newborns admitted to the Neonatal Intensive Care Unit and Neonatal Pathology of Cagliari University Hospital.

METHOD

This pilot study was prospectively conducted during a 1-month period and involved all newborns admitted to our hospital that received a pharmacotherapy. After obtaining written parental consent, data collected from each newborn included date of birth, sex, gestational age and weight. Also, diagnosis and information about each drug administered during the first month of life: dose, frequency, route of administration, and indication for use was collected.

RESULTS

Among the 79 newborn infants admitted to our hospital during the study period, 38 received a pharmacotherapy and were enrolled in our study. A total of 88 treatments were given: 41 (47%) followed the terms of the product license, 47 (53%) were used in an unlicensed or off-label manner.

CONCLUSION

Our results confirm this trend of drug use in the neonatological field and suggest the need to update information contained in the data sheets of medicines.

Off-label and unlicensed drug prescribing in three paediatric wards in Finland and review of the international literature

OBJECTIVES

In paediatric pharmacotherapy, many drugs are prescribed to be given in ways and for conditions not approved in the marketing authorization (MA). Thus, off-label prescribing of drugs with no MA is widespread in paediatric wards. However, drug MA status and clinical practices differ across countries. In this prospective study, we studied the prescribing of off-label and unlicensed drugs in three paediatric wards in a tertiary hospital in Finland. Furthermore, we reviewed previous published studies to provide an up-to-date international perspective on prescribing of off-label and unlicensed drugs for hospitalized children.

METHODS

During a 2-week period, prescriptions for patients under 18 years of age (median age 1*6 years) in three wards; neonatal intensive care unit (NICU), general paediatric ward and paediatric surgical ward were recorded daily and drug-licensing status of all prescriptions was determined according to the approved summary of product characteristics. Published studies were retrieved through electronic searches, including MEDLINE (PubMed).

RESULTS

Of the 141 children, 108 received 629 prescriptions. Of the 108 children with a prescription, 82 (76%) had at least one off-label or unlicensed drug prescribed; 79% in the NICU, 63% in the general ward and 91% in the surgical ward (P = 0*014). Of the 108 children with a prescription, 26 (24%) received prescriptions for licensed drugs, 71 (66%) received prescriptions off-label and 36 (33%) for unlicensed drugs. Of all 629 prescriptions, 321 (51%) were for licensed drugs, 226 (36%) for off-label and 82 (13%) for unlicensed drugs. International studies showed similar extents of off-label and unlicensed-drug prescribing.

CONCLUSION

This study indicates that the use of off-label and unlicensed drugs is widespread in all the different paediatric wards surveyed and was as extensive as those reported for other countries.

The Task-force in Europe for Drug Development for the Young (TEDDY) Network of Excellence

The Task-force in Europe for Drug Development for the Young (TEDDY) was established in 2005 to contribute to the promotion of safe and efficacious medicines for children in the context of the impending European Paediatric Regulation that finally came into force in January 2007. The project includes seven objectives and 12 Work-Packages encompassing the main aspects of the development and use of pediatric drugs. TEDDY represents a new entity in the pediatric pharmaceutical field, differing from a Scientific Society, a network for developing research or trials, or a consultative regulatory body. The ambition of TEDDY is to support the existing pediatric networks, societies, and regulatory bodies in performing innovative initiatives, including those in areas in which such undertakings would not be feasible without supportive action. To accomplish its aim, TEDDY has focused on three different actions: (i) increasing awareness about the Paediatric Regulation revolution; (ii) reaching consensus on terms and instruments to be used for common research; and (iii) favoring close relationships among different stakeholders and partners from different EU Member States. After 3 years of activities, many results have been produced by the Network: surveys, databases, expert opinions, and recommendations. Linking together different stakeholders, including industry and patient associations, as well as academia and research centers, the Network has contributed to increasing awareness and participation in the Paediatric Regulation. In addition, many papers detailing original results have either been published or submitted for publication in peer-reviewed journals. TEDDY is an original Network whose identity and role as a catalyzer of initiatives related to the use and development of pediatric drugs needs to be better clarified in the near future. Of particular importance is the need to reach consensus on best practices. The lack of a common view on pediatric research requirements among stakeholders across Member States remains the main challenge to be overcome.

EU initiatives for research involving children

Further to recent correspondence in the medical press regarding the UK approach (Editorial in Lancet 367:1953, 2006; Smyth and Edwards in Lancet 368:645-646, 2006) to the Paediatric Medicines Regulation (Regulation (EC) no. 1901/2006, 2006), which has now entered into force, we would like to make reference to a number of research-based initiatives of the European Union in this field.
