Abstract
AIMS To assess the extent of off-label drug use and the occurrence of suspected adverse drug reactions (ADRs) among paediatric patients in Italian hospitals. METHODS We conducted a 2-year prospective cohort study across 22 Italian hospital wards from September 2020 to September 2022. As part of the surveillance project, we performed a 6-month retrieval of all reported ADRs and evaluated all drug prescriptions for their possible off-label use. Following an educational project on pharmacovigilance addressed to healthcare professionals in participating wards, the same data collection was performed. RESULTS Among the 892 patients included in the study, 64% were admitted to paediatric wards and 36% to neonatal wards. Fifty per cent of all drugs prescribed were used off-label and mainly concerned the administration of a different dose from the one authorized. In neonatal wards, off-label prescriptions occurred slightly more often, with antibacterials being the most frequently used off-label drugs. A total of 35 reports of suspected ADRs were collected, five before the educational project and 30 afterwards. Based on product licence, 10 of the total 35 reports concerned at least one off-label drug use. CONCLUSIONS The off-label use of drugs in treating paediatric patients was extensive in Italian hospitals. Regulatory interventions are needed to promote the use of drugs based on the latest available literature and improve ADR reporting on children. Paediatric indications and dosages of the drugs most commonly used in children should be supported by appropriate ad hoc studies.

Estimated distribution of malaria cases among children in sub-Saharan Africa by specified age categories using data from the Global Burden of Diseases 2019. Malar J 2023; 22:371. [PMID: 38053100 DOI: 10.1186/s12936-023-04811-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Accepted: 11/29/2023] [Indexed: 12/07/2023] Open
Abstract
BACKGROUND Children in sub-Saharan Africa (SSA) remain the most vulnerable to malaria and malaria mortality. This study estimated the disease burden and distribution of Plasmodium falciparum malaria among children with age categories (0 to < 2 years, 2 to < 6 years, 6 to < 12 years, ≥ 12 years) in SSA. METHODS Data on the number of cases and incidence rates of P. falciparum malaria by age group from the Institute of Health Metrics and Evaluation (GBD 2019) for 11 countries in SSA was employed in this study. The best-fitting distribution of P. falciparum malaria cases by prespecified age categories was derived using a combination of a Log-normal and Weibull distribution. RESULTS Plasmodium falciparum malaria was 15.4% for ages 0 to < 2 years, 30.5% for 2 to < 6 years, 17.6% for 6 to < 12 years, and 36.5% for ≥ 12 years based on data from countries in SSA. The results have important implications for the current drive by the FDA and EMA to ensure the representativeness of real-world populations in clinical trials evaluating the safety and efficacy of medication exposure. CONCLUSIONS The theoretical distributions of P. falciparum malaria will help guide researchers in ensuring that children are appropriately represented in clinical trials and other interventions aiming to address the current burden of malaria in SSA.

Optimizing therapeutic decision-making for off-label medicines use: A scoping review and consensus recommendations for improving practice and research . Pharmacoepidemiol Drug Saf 2023; 32:1200-1222. [PMID: 37208845 PMCID: PMC10543391 DOI: 10.1002/pds.5640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 05/02/2023] [Accepted: 05/11/2023] [Indexed: 05/21/2023]
Abstract
PURPOSE Off-label medicines use is a common and sometimes necessary practice in many populations, with important clinical, ethical and financial consequences, including potential unintended harm or lack of effectiveness. No internationally recognized guidelines exist to aid decision-makers in applying research evidence to inform off-label medicines use. We aimed to critically evaluate current evidence informing decision-making for off-label use and to develop consensus recommendations to improve future practice and research. METHODS We conducted a scoping review to summarize the literature on available off-label use guidance, including types, extent and scientific rigor of evidence incorporated. Findings informed the development of consensus recommendations by an international multidisciplinary Expert Panel using a modified Delphi process. Our target audience includes clinicians, patients and caregivers, researchers, regulators, sponsors, health technology assessment bodies, payers and policy makers. RESULTS We found 31 published guidance documents on therapeutic decision-making for off-label use. Of 20 guidances with general recommendations, only 35% detailed the types and quality of evidence needed and the processes for its evaluation to reach sound, ethical decisions about appropriate use. There was no globally recognized guidance. To optimize future therapeutic decision-making, we recommend: (1) seeking rigorous scientific evidence; (2) utilizing diverse expertise in evidence evaluation and synthesis; (3) using rigorous processes to formulate recommendations for appropriate use; (4) linking off-label use with timely conduct of clinically meaningful research (including real-world evidence) to address knowledge gaps quickly; and (5) fostering partnerships between clinical decision-makers, researchers, regulators, policy makers, and sponsors to facilitate cohesive implementation and evaluation of these recommendations. CONCLUSIONS We provide comprehensive consensus recommendations to optimize therapeutic decision-making for off-label medicines use and concurrently drive clinically relevant research. Successful implementation requires appropriate funding and infrastructure support to engage necessary stakeholders and foster relevant partnerships, representing significant challenges that policy makers must urgently address.

Abstract
Psychotropics are increasingly used in pediatrics, often as off-label medicines. The guarantees of safety and efficacy are not always granted in clinical practice compared to adult authorised indications. A retrospective observational study was done to estimate the prevalence of psychotropic use in pediatric subjects of Catalonia (Spain). Anonymised data on dispensation of psychotropics to pediatric patients, demography and other related data were obtained by the local healthcare management for the period 2008-2017. Estimation of off-label use was done through description of drug dispensations with no authorised use related to age range. The prevalence of psychotropics was 40.8-64.2 per 1,000 pediatric inhabitants. Hydroxyzine-only represented two-thirds of dispensations, and when removed, the prevalence dropped to 26.4-32.2 per 1,000 pediatric inhabitants. Adolescents and boys were more likely to receive a psychotropic. Psychostimulants had the highest exposure rate, mainly due to methylphenidate. Off-label use was observed in 12% of subjects, corresponding to 4.6% of all dispensed psychotropics with boys being more exposed. The proportion of off-label use vs. labelled use was higher in younger populations. Aripiprazole had the highest off-label frequency. Our data support the frequent reality of off-label use in pediatrics, despite the potential underestimation related to the selected off-label definition. There is an urgent need to systematically ascertain effectiveness and any potential adverse events in the off-label pediatric setting, and to generate valuable information for risk-benefit assessment in these populations where extrapolation from adults is not reliable.

Abstract
Despite various international regulatory initiatives over the last 20 years, many challenges remain in the field of paediatric drug development and evaluation. Indeed, drug research and development is still focused essentially on adult indications, thereby excluding many paediatric patients, limiting the feasibility of trials and favouring competing developments. Off-label prescribing persists and the development of age-appropriate dosage forms for children remains limited. Against this background, the members of this panel (TR) recommend the launch of multi-partner exchange forums on specific topics in order to focus new drug research and development on the real, unmet medical needs of children and adolescents, and in keeping with the underlying mechanisms of action. Scientific information sharing and cooperation between stakeholders are also essential for defining reference evaluation methods in each medical field. These forums can be organised through existing paediatric facilities and research networks at the French and European level. The latter are specifically dedicated to paediatric research and can facilitate clinical trial implementation and patient enrolment. Moreover, specific grants and public/private partnerships are still needed to support studies on the repositioning of drugs in paediatric indications, and pharmacokinetic studies aimed at defining appropriate dosages. The development of new pharmaceutical forms, better suited for paediatric use, and the promotion of resulting innovations will stimulate future investments. Initiatives to gather observational safety and efficacy data following off-label and/or derogatory early access should also be encouraged to compensate for the lack of information available in these situations. Finally, the creation of Ethics Committees (EC) with a specific "mother-child" advisory expertise should be promoted to ensure that the current regulation (Jardé law in France) is implemented whilst also taking into account the paediatric specificities in medical trials.

Abstract
BACKGROUND The medicine selection method is a critical and challenging issue in medical insurance decision-making. OBJECTIVES This study proposed a real-world data-based multi-criteria decision analysis (MCDA) model with a hybrid entropic weight Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) algorithms to select satisfactory drugs. METHODS The evaluation index includes two levels: primary criteria and sub-criteria. Firstly, we proposed six primary criteria to form the value health framework. The primary criteria's weights were derived from the policymakers' questionnaire. Meanwhile, clinically relevant sub-criteria were derived from high-quality (screened by GRADE scores) clinical-research literature. Their weights are determined by the entropy weight (EW) algorithm. Secondly, we split the primary criteria into six mini-EW-TOPSIS models. Then, we obtained six ideal closeness degree scores (ICDS) for each candidate drug. Thirdly, we get the total utility score by linear weighting the ICDS. The higher the utility score, the higher the ranking. RESULTS A national multicenter real-world case study of the ranking of four generic antibiotics validated the proposed model. This model is verified by comparative experiments and sensitivity analysis. The whole ranking model was consistent and reliable. Based on these results, medical policymakers can intuitively and easily understand the characteristics of each drug to facilitate follow-up drug policy-making. CONCLUSION The ranking algorithm combines the objective characteristics of medicine and policy makers' opinions, which can improve the applicability of the results. This model can help decision-makers, clinicians, and related researchers better understand the drug assessment process.

Abstract
Many drugs are still prescribed off-label to the pediatric population. Although off-label drug use not supported by high level of evidence is potentially harmful, a comprehensive overview of the quality of the evidence pertaining off-label drug use in children is lacking. The Dutch Pediatric Formulary (DPF) provides best evidence-based dosing guidelines for drugs used in children. For each drug-indication-age group combination-together compiling one record-we scored the highest available level of evidence: labeled use, systematic review or meta-analysis, randomized controlled trial (RCT), comparative research, noncomparative research, or consensus-based expert opinions. For records based on selected guidelines, the original sources were not reviewed. These records were scored as guideline. A total of 774 drugs were analyzed comprising a total of 6,426 records. Of all off-label records (n = 2,718), 14% were supported by high quality evidence (4% meta-analysis or systematic reviews, 10% RCTs of high quality), 20% by comparative research, 14% by noncomparative research, 37% by consensus-based expert opinions, and 15% by selected guidelines. Fifty-eight percent of all records were authorized, increasing with age from 30% in preterm neonates (n = 110) up to 64% in adolescents (n = 1,630). Many have advocated that off-label use is only justified when supported by a high level of evidence. We show that this prerequisite would seriously limit available drug treatment for children as the underlying evidence is low across ages and drug classes. Our data identify the drugs and therapeutic areas for which evidence is clearly missing and could drive the global research agenda.

Abstract
In the UK, medicines for chronic conditions in children and young people (CYP) are typically initiated within secondary or tertiary care, with responsibility for ongoing supply often then passed to the child's general practitioner (GP) and community pharmacist. The patient should then be reviewed in regular specialist clinics, with two-way communication for any changes in medications or clinical status undertaken between primary and secondary/tertiary care. This arrangement allows long-term medications to be obtained close to home.Although this is what parents expect, the reality is often messy, with families regularly needing to source some medicines from the GPs and others via hospitals or homecare services. In addition, these arrangements are not uniform, they vary across different areas of the UK and depend on individual GP or hospital prescriber acceptance. When neither primary, secondary or tertiary care accepts it is their responsibility to prescribe, or patients are under multiple specialists, families often feel left to navigate this complex and variable supply system themselves. Obtaining a prescription is only the start of the process for families as dispensing from a community pharmacy can also be challenging.In this article, we set out the barriers and potential solutions to this complex issue. We use the term specialist prescribers to include not only paediatricians but all other specialists looking after CYP including child and adolescent psychiatrists, ophthalmologists, dermatologists, surgeons, etc, as well as non-medical prescribers.

Abstract
Introduction The paucity of pediatric clinical trials has led to many medicines frequently prescribed to children without a license for use in pediatrics, resulting in an increased risk of adverse drug reactions. Pharmacovigilance databases remain, among others, a valuable tool for evaluating pediatric drug safety in the real-life setting. Objective We aimed to characterize pediatric adverse drug reactions reported in the Italian Pharmacovigilance database coming from the Calabria region (Southern Italy) over 10 years. Methods All Individual Case Safety Reports (ICSRs) concerning individuals aged under 18 years were extracted from 2010 to 2019. Duplicate and vaccine ICSRs were excluded. The remaining ICSRs were analyzed with respect to patients’ demographic data, suspected drugs, and category of adverse drug reactions across different age groups. Results Among 6529 selected ICSRs, 395 pediatric ICSRs corresponding to 556 adverse drug reactions were analyzed. From 2010 to 2015, an increasing number of ICSRs were observed, but the reporting rate decreased after 2015. The highest proportion of ICSRs concerned children and adolescents. Around 52% of ICSRs involved boys: a trend observed in all age groups excluding newborns. Sixty ICSRs were serious and among them, 75% required hospitalization mainly in children and adolescents. Most of the ICSRs were issued by physicians (64.1%), followed by other healthcare professionals (22.5%) and pharmacists (9.9%). Anti-infective agents for systemic use and skin disorders were, respectively, the most frequently reported drug group and adverse drug reaction category. Conclusions This study provides an overview of adverse drug reactions reported in the pediatric population of the Calabria region and emphasizes the need for strengthening the surveillance in specific age subgroups and on given drugs in relation to their pattern of use. Supplementary Information The online version contains supplementary material available at 10.1007/s40264-022-01232-w.

Quality of Active versus Spontaneous Reporting of Adverse Drug Reactions in Pediatric Patients: Relevance for Pharmacovigilance and Knowledge in Pediatric Medical Care. Pharmaceuticals (Basel) 2022; 15:ph15091148. [PMID: 36145369 PMCID: PMC9503115 DOI: 10.3390/ph15091148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Revised: 09/03/2022] [Accepted: 09/05/2022] [Indexed: 11/19/2022] Open
Abstract
For drug safety in pediatric patients, knowledge about adverse drug reactions (ADRs) is essential to balance benefits and risks, especially because of the high incidence of off-label drug use. However, underreporting of ADRs is a serious problem, leading to a deficit in knowledge affecting clinical practice. The aim of this study is to find a method by which we can improve the quantity of ADR reporting while maintaining or improving the quality of the ADR reports. This was done in several steps. First, health care providers were educated to increase awareness of ADRs. Thereafter, a novel active supporting system was introduced, where reporting ADRs was simplified; if clinical physicians suspected an ADR, they only had to send the name or hospital number of the patient, the observed ADR, and the suspected drug to a supportive team. This team collects all information needed about the possible ADR from the patient’s medical records and hospital charts. With this information, the supportive team fills in the forms necessary for reporting ADRs to the nationwide pharmacovigilance centre Lareb. With this system, the quantity of ADR reports from both inpatients and outpatients rose dramatically. Subsequently, the quality of the obtained ADR reports was measured using the ClinDoc and vigiGrade systems. This study shows there is no loss of quality of the ADR reports in the active reporting system compared to spontaneous reporting systems. Based on the data of the present study, we suggest that an active reporting system has the potential to increase our knowledge about ADRs in pediatric patients.

Intercepting Medication Errors in Pediatric In-patients Using a Prescription Pre-audit Intelligent Decision System: A Single-center Study. Paediatr Drugs 2022; 24:555-562. [PMID: 35906499 DOI: 10.1007/s40272-022-00521-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 06/07/2022] [Indexed: 11/27/2022]
Abstract
OBJECTIVES Medication errors can happen at any phase of the medication process at health care settings. The objective of this study is to identify the characteristics of severe prescribing errors at a pediatric hospital in the inpatient setting and to provide recommendations to improve medication safety and rational drug use. METHODS This descriptive retrospective study was conducted at a tertiary pediatric hospital using data collected from Jan. 1st, 2019 to Dec. 31st, 2020. During this period, the Prescription Pre-audit Intelligent Decision System was implemented. Medication orders with potential severe errors would trigger a Level 7 alert and would be intercepted before it reached the pharmacy. Trained pharmacists maintained the system and facilitated decision making when necessary. For each order intercepted by the system the following patient details were recorded and analyzed: patient age, patient's department, drug classification, dosage forms, route of administration, and the type of error. RESULTS A total of 2176 Level 7 medication orders were intercepted. The most common errors were associated with drug dosage, administration route, and dose frequency, accounting for 35.2%, 32.8% and 13.2%, respectively. Of all the intercepted oerrors. 53.6% occurred in infants aged < 1 year. Administration routes involved were mainly intravenous, oral and external use drugs. Most alerts came from the neonatology department and constituted 40.5% of the total alerts, followed by the nephrology department 15.9% and pediatric intensive care unit (PICU) 11.3%. As to dosage forms, injections accounted for 50.4% of alerts, with 21.3% attributable to topical solutions, 9.1% to tablets, and 5.7% to inhalation. Anti-infective agents were the most common therapeutic drugs prescribed with errors. CONCLUSIONS The Prescription Pre-audit Intelligent Decision System, with the supervision of trained pharmacists can validate prescriptions, increase prescription accuracy, and improve drug safety for hospitalized children. It is a medical service model worthy of consideration.

Abstract
Neonates continue to be treated with off-label or unlicensed drugs while in hospital. However, some medications that have previously been used in adults underwent clinical testing and licensure for use with a different indication in the neonatal and pediatric population. Almost always, the marketing of these newly approved substances in a niche indication is accompanied by a steep increase in the price of the compound. We investigated the use of the approved formulation or the cheaper off-label alternative of Ibuprofen (Pedea®), Propanolol (Hemangiol®) and Caffeine Citrate (Peyona®) in neonatal clinical practice by conducting a National Survey of 214 Perinatal Centers in Germany. We also assessed price differences between on- and off-label alternatives and the extend of the clinical development program of the on-label medication in the neonatal population. On-label medication was more frequently used than the off-label alternative in all indications (PDA: on-label to off-label ratio 1:0.26, Apnea: 1:0.56, Hemangioma 1:0.76). All sponsors did conduct placebo-controlled Phase III trials with efficacy and safety endpoints in the target population and the number of participants in the target population varied between 82 and 497. Costs for the three drugs in their approved and marketed formulations increased in median 405-fold compared with the corresponding off-label alternative. Overall, about one out of three neonatologists prescribed an off-label or non-approved drug to patients despite an alternative medication that is approved for the indication in the target population being available.

Abstract
Ours is a cross-sectional, descriptive, retrospective study evaluating the extent of off-label prescribing for patients attending a university paediatric outpatient department in Goiás, Brazil. 391 patients were treated in the outpatient, and 668 medicines were prescribed. Of these, 70.4% followed the terms of the marketing authorization; 0.3% were unlicenced, and 11% were off-label. Dose was the main factor in off-label prescribing. Infants (0-2 years) received 37.8% of the off-label prescriptions. Vitamins and drugs for the treatment of respiratory diseases were the most prevalent culprits. Of the total prescriptions, 23 different drugs were defined as off-label. Salbutamol was the most prescribed (41.9%). Owing to practical and legal difficulties in carrying out clinical trials, medicines are inadequately studied in children; cooperation between industry, regulatory authorities, and healthcare professionals is required to improve treatment safety. Our results may help guide clinical researcher on off-label prescripting in future trials.

Abstract
Objective Prescribing a drug for a child is not an easy task and requires using the best available evidence as a guide, especially when a drug is used off-label. The practice of prescribing a drug for off-label use is fairly widespread worldwide. The FDA does not regulate prescribing patterns or practices of individual practitioners and, therefore, allows off-label use. The main objective of this study is to evaluate off-label prescribing among the pediatric population in the Kingdom of Saudi Arabia (KSA). Method This is a retrospective, simple random selection observational study of children (≤15 years) who visited pediatric clinics and had at least 1 drug prescribed over a 12-month period (January to December 2018). Results A total of 865 drugs (mean 1 and SD 0.24) were prescribed to 326 children. Off-label was identified in 39.4% of the drugs with a frequency of 512 (as 1 drug may belong to more than 1 off-label category). The most common reason for off-label prescribing was related to doses that were "higher or lower than the recommended use" (48.6%), and the most frequently identified drug class prescribed for off-label use was anti-infective drugs for systemic use (39.9%). The percentage of off-label drug use was found to be higher in girls and in the age group of 1 month to 2 years (P = .001) for both variables. In addition, a significant association was found between off label drug use and the total number of drugs prescribed, P < .001. Conclusion The findings of this study showed a high incidence of off-label prescribing mainly related to dosing and indication. The results of this observational study support the need to establish a unified national pediatric dosing formulary guide to ensure safe drug use in pediatrics.

Abstract
Background Off-label uses of medicines are common in pediatrics. The literature reports that at least one-third of children in hospital and up to 90% of newborns in neonatal intensive care units receive off-label prescriptions. Moreover, the lack of data on safety and efficacy in the pediatric population may sometimes increase the risk of adverse drug reactions. Objective This paper aims to (a) map the main gaps in the existing EU and US regulatory frameworks for pediatric drug development and off-label use and (b) propose potential solutions for further discussion. Conclusion The selected jurisdictions aim to limit off-label prescribing, but implementation levels generally seem low, including in pediatric settings. Subject to further research, we propose potential concerted actions and initiatives of international cooperation to fill this gap. In particular, regulators and pediatric societies could strengthen manufacturers' incentives to develop pediatric medicines, pediatricians' information about off-label uses, and patients' and parents' awareness.

Abstract
Treatment of children with cancer requires access to and reimbursement of effective drugs. Children with haemato-oncological diseases are often treated according to established treatment recommendations or in the framework of late-phase clinical trials. These often involve the use of drugs authorised for adults but which, however, have been used for many years in paediatrics with no perspective of authorisation in children. In Belgium, medicines are predominantly reimbursed based on their authorised indication. As a consequence, many drugs used in paediatric haemato-oncology are used off-label, despite their status of 'standard of care'. As reimbursement is often not available, alternative ways for funding need to be explored, which causes a significant administrative burden for healthcare providers and emotional distress for the parents. Solutions to organise a systematic reimbursement of standard of care off-label used drugs are described.Conclusion: A number of structural solutions are proposed, and we hope that they might guide health authorities to provide a solution to the problem caused by the lack of reimbursement of some standard of care medicines for children with cancer. What is Known: • Off-label drug use is frequently observed in paediatric haemato-oncology and compromises-in some countries-reimbursement. What is New: • An estimation of the impact of non-reimbursed drugs in Belgium is provided. • Some solutions are presented to overcome this problem in Belgium.

Abstract
Background The EU’s 2006 Paediatric Regulation aims to support authorisation of medicine for children, thus effectively increasing paediatric research. It is ethically imperative to simultaneously establish procedures that protect children’s rights. Method This study endeavours (a) to evaluate whether a template consent form designed by the Standing Working Group of the German-Research-Ethics-Committees (AKEK) adequately informs adolescents about research participation, and (b) to investigate associated phenomena like therapeutic misconception and motives for research participation. In March 2016 a questionnaire study was conducted among 279 pupils (mean age 13.1 years) of a secondary school in northern Germany. Results A majority of participants showed a general good understanding of foundational research ethics concepts as understood from the AKEK consent form. Nevertheless, our data also suggests possible susceptibility to therapeutic misconception. Own health concerns and pro-social considerations were found to be significant motivational factors for participating in research, while anticipation of pain lessens likelihood of participation. Advice from trusted others is an important decisional influence, too. Furthermore, data security was found to be a relevant aspect of adolescents’ decision-making process. Conclusion Bearing in mind adolescents’ generally good understanding, we infer the lack of knowledge about medical research in general to be one source of therapeutic misconception. To further improve the quality of consent we propose a multi-staged approach whereby general research education is completed before an individual becomes a patient or potential participant. To the best of our knowledge this is the first German questionnaire-study addressing issues of informed consent in a large under-age sample.

Accuracy of Dose Administered to Children Using Off-Labelled or Unlicensed Oral Dosage Forms. Pharmaceutics 2021; 13:pharmaceutics13071014. [PMID: 34371705 PMCID: PMC8308974 DOI: 10.3390/pharmaceutics13071014] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 06/30/2021] [Accepted: 07/01/2021] [Indexed: 12/05/2022] Open
Abstract
The pediatric population suffers from a lack of age-appropriate medicines leading to unsafe situations when off-labelled or unlicensed drugs are used. Assessing the best option to administrate medicines when manipulations are required is essential in order to improve child care. This study aimed to compare the accuracy of the administered dose provided by three dosage forms and their techniques of administration. Different techniques of administration were assessed, covering three oral dosage forms (commercially available tablets, capsules, oral suspensions) using two APIs not available in a children-adapted dosage form. Techniques of administration were simulated and administered doses were determined using HPLC-UV. Means were compared to the target dose while distributions of doses were compared between each technique. For both APIs, mean administered doses obtained with capsules and tablets were significantly different from the target dose, whereas there was no statistical difference with oral suspensions. Distributions of doses showed significant difference between the three dosage forms. This study demonstrates that manipulations of solid oral dosage forms provide dramatic underdosing leading to unsafe situations. Compounded oral suspension is the best option to avoid underdosing and dose variation. This solution should be prioritized when age-appropriate commercial medicines are not available.

Abstract
OBJECTIVE Determine the associations between neonatal intensive care unit (NICU) medication safety practices, laboratory-based adverse events (lab-AEs), and death. STUDY DESIGN We combined data from a 2016 survey of Pediatrix NICUs on use of medication safety practices with 2014-2016 infant data. We grouped NICUs based on the number of safety practices used (≤5, 6-7, and 8-10) and evaluated the association between the number of safety practices used and lab-AEs and deaths using logistic regressions. RESULTS Of the 94 NICUs included, 17% used ≤5 medication safety practices, 51% used 6-7, and 32% used 8-10. NICUs with more safety practices did not have a difference in lab-AEs or death. CONCLUSION In this cohort, the use of more medication safety practices was not associated with fewer lab-AEs or decreased death.

Abstract
Substandard and falsified (SF) medicines are a global issue contributing to antimicrobial resistance and causing economic and humanitarian harm. To direct law enforcement efficiently, halt the spread of SF medicines and antimicrobial resistance, academics, NGOs and government organisations use medicine quality sampling studies to estimate the prevalence of the problem. A systematic review of medicine quality studies was conducted to estimate how the methodological quality of these studies and SF prevalence has changed between 2013 and 2018. We also aimed to critique medicine sampling study methodologies, and the systematic review process which generates prevalence estimates. Based on 33 studies, the overall estimated median (Q1-Q3) prevalence of SF medicines appears to have remained high at 25% (7.7%-34%) compared with 28.5% in 2013. Furthermore, the methodological quality of prevalence studies has improved over the last 25 years. Definitive conclusions regarding the prevalence of SF medicines cannot be drawn due to the variability in sample sizes, consistency of design methods, and a lack of information concerning contextual factors affecting medicine quality studies. We contend that studies which present cumulative average prevalence figures are useful in a broad sense but could be improved to create more reliable estimates. We propose that medicine quality studies record the context of the study environment to allow systematic reviewers to compare like with like. Although, the academic rigour of medicine quality studies is improving, medicine sampling study limitations still exist. These limitations inhibit the accurate estimation of SF medicine prevalence which is needed to support detailed policy changes.

Abstract
INTRODUCTION To date, few studies have shown a significant association between off-label drug use and adverse drug reactions (ADRs). The main aims of this study is to evaluate the relationship between adverse drug reactions and unlicensed or off-label drugs in hospitalized children and to provide more information on prescribing practice, the amplitude, consequences of unlicensed or off-label drug use in pediatric inpatients. METHODS In this multicenter prospective study started from 2013, we use the French summaries of product characteristics in Theriaque (a prescription products guide) as a primary reference source for determining pediatric drug labeling. The detection of ADRs is carried out spontaneously by health professionals and actively by research groups using a trigger tool and patients' electronic health records. The causality between suspected ADRs and medication is evaluated using the Naranjo and the French methods of imputability independently by pharmacovigilance center. All suspected ADRs are submitted for a second evaluation by an independent pharmacovigilance experts. STRENGTH AND LIMITATIONS OF THIS STUDY For our best knowledge, EREMI is the first large multicenter prospective and objective study in France with an active ADRs monitoring and independent ADRs validation. This study identifies the risk factors that could be used to adjust preventive actions in children's care, guides future research in the field and increases the awareness of physicians in off-label drug use and in detecting and declaring ADRs. As data are obtained through extraction of information from hospital database and medical records, there is likely to be some under-reporting of items or missing data. In this study the field specialists detect all adverse events, experts in pharmacovigilance centers assess them and finally only the ADRs assessed by the independent committee are confirmed. Although we recruit a high number of patients, this observational study is subject to different confounders.

Abstract
The neonatal and pediatric populations have long been neglected concerning the development of oral dosage forms. For close to two decades, caregivers have had to adjust the doses of the off-label medicines and drugs for adults to suit the neonatal and pediatric needs. This is due to the lack of rules and regulations regarding neonates and pediatrics clinical trials while pharmaceutical industries see this as a non-lucrative approach. Despite such limitations, the administration of solid and liquid dosage forms to neonates and pediatrics necessitates the development of new technologies and even new strategies to meet the needs. Current approaches have not only focused on the development of suitable dosage forms but also the advancement of devices to enhance drug administration to pediatrics and neonates. Though current approaches have significantly added to the number of pediatric and neonatal oral dosage formulations on the market, there is still more room for improvement(s). While novel dosage forms including multiparticulates, orodispersible tablets/films, and chewable tablets have extensively been researched, some administration devices (e.g., nipple shield, pill swallowing cup, and solid dosage pen) have also been explored. Although a few of these products are in the market, the concerted efforts of regulation administrative bodies, pharmaceutical industry settings, and scientists in academia have been oriented to address all issues and advance the neonatal and pediatric-centric pharmaceutical products.

Abstract
Introduction As asthma medications are frequently prescribed for children, knowledge of the safety of these drugs in the paediatric population is important. Although spontaneous reports cannot be used to prove causality of adverse events, they are important in the detection of safety signals. Objective Our objective was to provide an overview of adverse drug events associated with asthma medications in children from a spontaneous reports database and to identify new signals. Methods Spontaneous reports concerning asthma drugs were obtained from EudraVigilance, the European Medicine Agency’s database for suspected adverse drug reactions. For each drug–event combination, we calculated the proportional reporting ratio (PRR) in the study period 2011–2017. Signals in children (aged 0–17 years) were compared with signals in the whole population. Analyses were repeated for different age categories, by sex and by therapeutic area. Results In total, 372,345 reports in children resulted in 385 different signals concerning asthma therapy. The largest group consisted of psychiatric events (65 signals). Only 30 signals were new, with seven, including herpes viral infections, associated with omalizumab. Stratification by age, sex and therapeutic area provided additional new signals, such as hypertrichoses with budesonide and encephalopathies with theophylline. Of all signals in children, 60 (16%) did not appear in the whole population. Conclusions The majority of signals regarding asthma therapy in children were already known, but we also identified new signals. We showed that signals can be masked if age stratification is not conducted. Further exploration is needed to investigate the risk and causality of the newly found signals.

Abstract
OBJECTIVE To evaluate unlicensed and off-label prescription and use of drugs to children in primary health care. METHODS This is a systematic review that was written based on Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). The studies were extracted from the databases: LILACS, PubMed/MEDLINE, and Scopus. Studies in English, Spanish or Portuguese with abstract available regarding the use and prescription of off-label and unlicensed drugs to children aged 0-18 years in primary health care were included. The evaluation of the titles, abstracts and Full-text were performed independently by two reviewers, and the divergences were resolved by a third reviewer. RESULTS Six studies were included. The incidence of off-label prescription varied from 29.5% to 51.7% in relation to the total number of drugs prescribed. The prevalence of off-label drugs ranged from 31.7% to 93.5% in relation to the total number of drugs prescribed. It was observed a higher proportion of off-label prescription related to age and dose. For unlicensed drugs, there was a small variation in incidence between 2.4% and 3.9%, relative to the total number of prescriptions, or between 2.4% and 10.0%, relative to the sample size. It was observed a higher proportion of unlicensed prescription related to children under 2 years of age. CONCLUSIONS The unlicensed and off-label prescription of drugs is recurring in the pediatric population of primary health care. It is necessary to have better information on these drugs by the regulatory agencies and the pharmaceutical industries for rational use of drugs in children.

Abstract
BACKGROUND Among factors influencing the higher risk of developing unknown or rare adverse drug reactions (ADRs) among children and adolescents, there is the frequent off-label use of drugs that seems to be very common in pediatric oncological patients. Our study aim to collect and evaluate data on the safety profile of antineoplastic drugs and their off-label use in the pediatrics population using real life data. METHODS We retrieved Individual Case Safety Reports (ICSRs) with an anticancer agent as suspected drug among those reported through the Campania spontaneous reporting system from 1 January 2013 to 30 September 2019. We classified ICSRs into four off-label categories: "age," "route of administration," "weight," and "therapeutic indication." We defined an ICSR as an off-label case if it met at least one of the aforementioned categories for at least one of the reported suspected antineoplastic drugs. RESULTS A total of 18 ICSRs (7.6%) out of 236 were classified as off-label cases. The median age of patients was 13 years (interquartile range, IQR: 6-16), with 94.4% of cases occurring in male patients. In the classification of the off-label category, 16 ICSRs were categorized according to the "therapeutic indication" and two for the "age." No case was categorized for the off-label categories "route of administration" and "weight." The two off-label cases categorized as "age" were both related to the use of brentuximab vedotin for Hodgkin's lymphoma in patients aged 16 years. Twenty-nine ADRs (1.6 suspected adverse drug reactions per ICSR) were identified among off-label cases. Among ADRs, those reported more than one were diarrhea (N = 3), neutropenia (N = 3), nausea (N = 2), pyrexia (N = 2), and vomit (N = 2). CONCLUSIONS Our findings showed a low number of ICSRs classified as off-label. The majority of off-label ICSRs were categorized for the "therapeutic indication." This low number of off-label ICSRs might be largely due to the underreporting phenomenon, which is a major limit in pharmacovigilance. Therefore, we believe that spreading pharmacovigilance knowledge and awareness might improve this aspect.

Abstract
Pharmacokinetic/pharmacodynamic (PKPD) modeling is important in the design and conduct of clinical pharmacology research in children. During drug development, PKPD modeling and simulation should underpin rational trial design and facilitate extrapolation to investigate efficacy and safety. The application of PKPD modeling to optimize dosing recommendations and therapeutic drug monitoring is also increasing, and PKPD model-based dose individualization will become a core feature of personalized medicine. Following extensive progress on pediatric PK modeling, a greater emphasis now needs to be placed on PD modeling to understand age-related changes in drug effects. This paper discusses the principles of PKPD modeling in the context of pediatric drug development, summarizing how important PK parameters, such as clearance (CL), are scaled with size and age, and highlights a standardized method for CL scaling in children. One standard scaling method would facilitate comparison of PK parameters across multiple studies, thus increasing the utility of existing PK models and facilitating optimal design of new studies.

Abstract
AIMS The risk to develop adverse drug reactions (ADRs) is high for paediatric patients. This is, amongst other reasons, due to the inevitable use of off-label and unlicensed medicines. Moreover, there is limited knowledge on ADRs in children. Thus, adequate recognition may be challenging. The lack of dedicated studies and the voluntary nature of pharmacovigilance systems used to gain insight into the characteristics of ADRs contribute to this problem. The goal of this study is to identify whether ADRs in paediatric patients are adequately documented by the medical team and whether they are subsequently reported to the national pharmacovigilance system. METHODS All patients admitted to the paediatric medium care of the Radboudumc Amalia Children's hospital during 1 month, and using one or more drugs, were included. Two researchers analysed retrospectively and independently the number of possible ADRs in the medical records. The ADRs were listed per paediatric subspecialty, to evaluate any differences in documentation and reporting of the ADRs. Subsequently, the causality, severity, and seriousness of the ADRs were assessed. The ADRs were categorised by system organ class and drug class. The national pharmacovigilance centre was consulted to check if there were any reports coming from our hospital and to collect the total number of reports. RESULTS The medical records of 301 patients were analysed, 81 patients were suffering from one or more ADRs. In total 132 suspected ADRs were found, divided among 19 different paediatric subspecialties. Numbers were too small to investigate the differences in ADR documentation. Of these found ADRs, 55% were not explicitly noted as such in the medical records by the treating physician. None of the ADRs were reported to the national pharmacovigilance centre. Most ADRs scored 'possible' in the causality assessment, were mild or moderate, and a small number were serious. The ADRs occurred in 25 different organ systems. In total 25 different drug classes were involved. CONCLUSIONS The results of the present study show that a large number of ADRs are not registered in the medical records and are not reported to the national pharmacovigilance system. Furthermore, it is shown that the number of ADRs occurring at our centre is much higher than the number reported to the national pharmacovigilance centre. Only an average of 513 ADRs in paediatric patients are reported per year nationwide, suggesting that there is extensive underreporting.

Abstract
Despite advances in regulations and initiatives to increase pediatric medicine development, there is still an unmet need for age-appropriate medicines for children. The availability of pediatric formulations is particularly lacking in resource poor areas, due to, for example, area-specific disease burden and financial constraints, as well as disconnected supply chains and fragmented healthcare systems. The paucity of authorized pediatric medicines often results in the manipulation and administration of products intended for adults, with an increased risk of mis-dosing and adverse reactions. This article provides an overview of the some of the key difficulties associated with the development of pediatric medicines in both high and low resource areas, and highlights shared and location specific challenges and opportunities. The utilization of dispersible oral dosage forms and suppositories for low and middle-income countries (LMICs) are described in addition to other platform technologies that may in the future offer opportunities for future pediatric medicine development for low resource settings.

Abstract
BACKGROUND Off-label drug use in children is common and potentially harmful. In most previous off-label use research, authors studied hospitalized children, specific drug classes, or non-US settings. We characterized frequencies, trends, and reasons for off-label systemic drug orders for children in ambulatory US settings. METHODS Using nationally representative surveys of office-based physicians (National Ambulatory Medical Care Surveys, 2006-2015), we studied off-label orders of systemic drugs for children age <18 based on US Food and Drug Administration-approved labeling for age, weight, and indication. We characterized the top classes and diagnoses with off-label orders and analyzed factors and trends of off-label orders using logistic regression. RESULTS Physicians ordered ≥1 off-label systemic drug at 18.5% (95% confidence interval: 17.7%-19.3%) of visits, usually (74.6%) because of unapproved conditions. Off-label ordering was most common proportionally in neonates (83%) and in absolute terms among adolescents (322 orders out of 1000 visits). Off-label ordering was associated with female sex, subspecialists, polypharmacy, and chronic conditions. Rates and reasons for off-label orders varied considerably by age. Relative and absolute rates of off-label orders rose over time. Among common classes, off-label orders for antihistamines and several psychotropics increased over time, whereas off-label orders for several classes of antibiotics were stable or declined. CONCLUSIONS US office-based physicians have ordered systemic drugs off label for children at increasing rates, most often for unapproved conditions, despite recent efforts to increase evidence and drug approvals for children. These findings can help inform education, research, and policies around effective, safe use of medications in children.

Abstract
Improving (feelings of) safety is an important goal of many health systems, especially in the context of recurrent threats of pandemics, and natural disasters. Measures to improve safety should be cost-effective, raising the issue of how to value safety. This is a complex task due to the intangible nature of safety. We aim to synthesize the current empirical literature on the evaluation of safety to gain insights into current methodological practices. After a thorough literature search in two databases for papers from the fields of life sciences, social sciences, physical sciences and health sciences that empirically measure the value of increasing safety, 33 papers were found and summarized. The focus of the research was to investigate the methodologies used. Attention was also paid to theoretical papers and the methodological issues they present, and the relationship between safety and three categories of covariate results: individual characteristics, individual relationship with risk, and study design. The field of research in which the most papers were found was environmental economics, followed by transportation and health. There appeared to be two main methods for valuating safety: Contingent Valuation and Discrete Choice Experiments, within which there were also differences-for example the use of open or dichotomous choice questions. Overall this paper finds that there still appears to be a long way ahead before consensus can be attained about a standardised methodology for valuating safety. Safety valuation research would benefit from learning from previous experience and the development of more standardised methods.

Abstract
Background Off-label prescribing in children is associated with several prerequisites such as ensuring sound and scientific evidence and obtaining written consent prior to use of off-label drugs to ensure that protection is provided to patients and healthcare professionals. Adherence to the pre-requisites depends on the attitude, views and knowledge of the pharmacists and doctors involved in this practice. Objective To explore the attitudes, knowledge and views on off-label prescribing in children among hospital-based pharmacists and paediatric doctors. Setting The study was conducted in a 620-bedded general hospital located in the urban area of central Peninsular Malaysia. Method Face to face, semi-structured interviews with 12 pharmacists and 12 paediatric doctors. Interviews were audio-recorded, transcribed and analysed using constant comparison method. Main outcome measure Themes surrounding hospital-based pharmacists' and paediatric doctors' attitude, knowledge and views on off-label prescribing in children. Results Four themes were derived: knowledge on off-label prescribing in children, views on off-label prescribing in children, attitude towards off-label prescribing in children and guidance on off-label prescribing in children. Conclusion There is a need to increase the knowledge of hospital-based pharmacists and paediatric doctors and address several concerns on off-label prescribing in children. The decision to prescribe or dispense off-label drugs involved collective decision-making mechanisms and guidance is required with regards to offlabel prescribing in children.

Abstract
The development of age-appropriate formulations should focus on dosage forms that can deliver variable yet accurate doses that are safe and acceptable to the child, are matched to his/her development and ability, and avoid medication errors. However, in the past decade, the medication needs of neonates have largely been neglected. The aim of this review is to expand on what differentiates the needs of preterm and term neonates from those of the older paediatric subsets, in terms of environment of care, ability to measure and administer the dose (from the perspective of the patient and carer, the routes of administration, the device and the product), neonatal biopharmaceutics and regulatory challenges. This review offers insight into those challenges posed by the formulation of medicinal products for neonatal patients in order to support the development of clinically relevant products.

Abstract
Phase 0 approaches, including microdosing, involve the use of sub-therapeutic exposures to the tested drugs, thus enabling safer, more-relevant, quicker and cheaper first-in-human (FIH) testing. These approaches also have considerable potential to limit the use of animals in human drug development. Recent years have witnessed progress in applications, methodology, operations, and drug development culture. Advances in applications saw an expansion in therapeutic areas, developmental scenarios and scientific objectives, in, for example, protein drug development and paediatric drug development. In the operational area, the increased sensitivity of Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS), expansion of the utility of Positron Emission Tomography (PET) imaging, and the introduction of Cavity Ring-Down Spectroscopy (CRDS), have led to the increased accessibility and utility of Phase 0 approaches, while reducing costs and exposure to radioactivity. PET has extended the application of microdosing, from its use as a predominant tool to record pharmacokinetics, to a method for recording target expression and target engagement, as well as cellular and tissue responses. Advances in methodology include adaptive Phase 0/Phase 1 designs, cassette and cocktail microdosing, and Intra-Target Microdosing (ITM), as well as novel modelling opportunities and simulations. Importantly, these methodologies increase the predictive power of extrapolation from microdose to therapeutic level exposures. However, possibly the most challenging domain in which progress has been made, is the culture of drug development. One of the main potential values of Phase 0 approaches is the opportunity to terminate development early, thus not only applying the principle of 'kill-early-kill-cheap' to enhance the efficiency of drug development, but also obviating the need for the full package of animal testing required for therapeutic level Phase 1 studies. Finally, we list developmental scenarios that utilised Phase 0 approaches in novel drug development.

Abstract
Background Many newborns may need to be hospitalized and receive drugs during the first days of their lives. These drugs are fundamentally prescribed as off-label and unlicensed. This study aimed to investigate the amount of these kinds of drugs administered in the Neonatal Intensive Care Units (NICUs) of Abuzar and Imam Khomeini Teaching Hospitals in Ahvaz, Iran. Methods This was a 3-month descriptive, cross-sectional study with retrospective nature in which 193 hospitalized newborns were studied. Demographic data were extracted from the patients’ files. The drugs were classified as off-label, unlicensed or licensed according to the Pediatric & Neonatal Dosage Handbook (Lexicomp®, 22nd Edition). Results In total, 1049 prescriptions were registered for the 193 hospitalized newborns (term and preterm). For each newborn, the mean numbers of prescriptions and drugs received were 5.4 and 4.5, respectively. The mean numbers of prescriptions and drugs were greater for preterm newborns. Of the total 1049 prescriptions, 38.1% were off-label and 1.9% were unlicensed. Of the 193 newborns, 85% received at least one off-label or unlicensed prescription. Off-label prescriptions were mostly related to dose (44.8%) and dosing interval (36.5%). Most off-label drugs were antibiotics (mainly Gentamicin). Albuterol was used off-label in 100% of the cases. Conclusions The results of the present study show that the prescription of off-label and unlicensed drugs in NICUs is as high in Iran as in other countries. This suggests that it is necessary to provide information to neonatologists to decrease the prescription of off-label and unlicensed drugs.

Abstract
BACKGROUND The EINSTEIN-Jr program will evaluate rivaroxaban for the treatment of venous thromboembolism (VTE) in children, targeting exposures similar to the 20 mg once-daily dose for adults. A physiologically based pharmacokinetic (PBPK) model for pediatric rivaroxaban dosing has been constructed. METHODS We quantitatively assessed the pharmacokinetics (PK) of a single rivaroxaban dose in children using population pharmacokinetic (PopPK) modelling and assessed the applicability of the PBPK model. Plasma concentration-time data from the EINSTEIN-Jr phase I study were analysed by non-compartmental and PopPK analyses and compared with the predictions of the PBPK model. Two rivaroxaban dose levels, equivalent to adult doses of rivaroxaban 10 mg and 20 mg, and two different formulations (tablet and oral suspension) were tested in children aged 0.5-18 years who had completed treatment for VTE. RESULTS PK data from 59 children were obtained. The observed plasma concentration-time profiles in all subjects were mostly within the 90% prediction interval, irrespective of dose or formulation. The PopPK estimates and non-compartmental analysis-derived PK parameters (in children aged ≥6 years) were in good agreement with the PBPK model predictions. CONCLUSIONS These results confirmed the applicability of the rivaroxaban pediatric PBPK model in the pediatric population aged 0.5-18 years, which in combination with the PopPK model, will be further used to guide dose selection for the treatment of VTE with rivaroxaban in EINSTEIN-Jr phase II and III studies.

Abstract
BACKGROUND In the past two decades, many legislative and regulatory initiatives were taken globally to improve drug use in children. However, children are still found to be prescribed with off-label drugs. This study was conducted to provide an overview of the worldwide trend in off-label prescribing in children from the year 1996 to 2016. DATA SOURCES The articles published in PubMed, MEDLINE and Google Scholar were searched using text words: off-label, unlicensed, paediatric and children. Additional articles were identified by reviewing the bibliography of the retrieved articles. Full-text articles published in English which reported on the prevalence of off-label prescribing in children between January 1996 and December 2016 were included. RESULTS A total of 101 studies met the inclusion criteria. Off-label prescribing definition included four main categories: age, indication, dose and route of administration. The three most common reference sources used in the studies were summary of product characteristics, national formularies and package inserts. Overall, the off-label prescribing rates in children ranged from 1.2 to 99.7%. The most common category of off-label prescribing in children was dose and age. CONCLUSIONS This review highlighted that off-label prescribing in children was found to be highly prevalent throughout the past two decades, persistently in the neonatal intensive care units. This suggests that besides legislative and regulatory initiatives, behavioural, knowledge aspects and efforts to integrate evidence into practice related to off-label prescribing also need to be evaluated and consolidated as part of the concerted efforts to narrow the gaps in prescribing for children.

Background Paediatric palliative care (PPC) aim to ensure the control of symptoms and the best possible quality of life for patients whose underlying disease, characterized by an unstoppable evolution and negative prognosis, no longer responds to specific treatments. The scientific evidence in this context are very deficient and, in order to obtain welfare objectives consistent with the situation, in the overwhelming majority of cases the prescription of drugs is off-label for indication of use and/or for age and/or for way of administration and/or formulation. The Agenzia Italiana del Farmaco - AIFA and the Italian Society of Palliative Care (Società Italiana di Cure Palliative - SICP), under a dedicated working group, wrote a document that collects the scientific evidence available to support the off-label use of medicines more frequently used in PPC. The goal is to certify the consolidated off-label use of these drugs and propose their use under the Law 648/96, in the absence of data from its pivotal clinical trials. Aim of the commentary is to report the conditions for this important work and to present the 10 drugs, usually used off-label in PPC and in pain therapy, now included in Law 648/96. Conclusion This work is deemed essential to resolve, at least in part, the lack of availability of medicines researched and approved.

Abstract
BACKGROUND The aim of this study was to explore the use of off-label/unlicensed drugs to confirm the safety and efficacy of their prescription in children in Korea. METHODS In this retrospective study, we analyzed data of patients who received any of the 32 drugs between January-December 2014 in tertiary hospitals in Korea, including demographics, diagnoses, reasons for the medication, administration route, and details of adverse drug reactions. Additionally, the mortality in the cohort was assessed. The primary outcomes were efficacy and safety, including mortality, of these drugs in pediatric patients. The secondary outcomes were the current statuses of the use of off-label/unlicensed drugs in two centers. RESULTS Totally, 5,130 prescriptions were found in 2,779 patients. Age (73.5%) and indication (11.7%) were the most frequent reasons for prescriptions being off-labeled/unlicensed. Approximately 88% of the prescriptions were effective, and 19% of the patients developed adverse drug reactions. The number of prescriptions was significantly higher in children with adverse drug reactions than it was in those without (2.8 vs. 1.5; P < 0.001). The number of prescribed off-label/unlicensed medicines and age at prescription were independently associated with adverse drug events (odds ratio, 1.55 and 1.1; P < 0.001 and 0.034, respectively). CONCLUSION Children are still prescribed medicines that are not authorized in terms of age, weight, indications, or routes of administration. Therefore, many old products require re-assessment of authorization. More prospective clinical studies should be performed to confirm the efficacy and safety of drugs in the pediatric population.

Abstract
OBJECTIVE To examine primary care patients' knowledge and attitudes on off-label treatment. METHODS In 47 primary care offices in Osijek-Baranja County, 1300 patients were given questionnaires about their knowledge and attitudes on off-label treatment. Questionnaires were completed voluntarily and anonymously. RESULTS Majority of patients (96.3%) had no knowledge about off-label treatment, and upon having it explained, 42.3% would not accept such treatment under any circumstances, while 54.5% would never accept such treatment for their children. Patients place more trust in primary care doctors than in hospital doctors; 69.6% of patients strongly believe that primary care doctors would not expose them to off-label treatment while only 41.2% of them think the same in relation to hospital doctors. In case of serious consequences following off-label therapy 49.9% of patients would sue doctors who prescribed it. CONCLUSION Patients in primary care possess limited knowledge about off-label treatment. Most patients do not wish to be exposed to such treatment, and are particularly reluctant to have their children exposed to it. In case of serious side effects, half of the patients would sue doctors who had prescribed the off-label therapy.

Abstract
Background To describe frequency, preventability and seriousness of adverse drug reactions (ADRs) in children as cause of emergency department (ED) admission and to evaluate the association between specific factors and the reporting of ADRs. Methods A retrospective analysis based on reports of suspected ADRs collected between January 1st, 2012 and December 31st, 2016 in the ED of Meyer Children’s Hospital (Italy). Demographics, clinical status, suspected drugs, ADR description, and its degree of seriousness were collected. Logistic regression was used to estimate the reporting odds ratios (RORs) with 95% confidence intervals (CIs) of potential predictors of ADR seriousness. Results Within 5 years, we observed 834 ADRs (1100 drug-ADR pairs), of whom 239 were serious; of them, 224 led to hospitalization. Patients were mostly treated with one drug. Among patients treated with more than one drug, 78 ADRs presented a potential interaction. The most frequently reported ADRs involved gastrointestinal system. The most frequently reported medication class was antinfectives. Risk of serious ADR was significantly lower in children and infants compared to adolescents (ROR 0.41 [95% CI: 0.27–0.61] and 0.47 [0.32–0.71], respectively), and it was significantly increased in subjects exposed to more than one drug (ROR 1.87 [1.33–2.62] and 3.01 [2.07–4.37] for subjects exposed to 2 and 3 or more drugs, respectively). Gender, interactions and off-label drug use did not influence the risk of serious ADRs. Conclusion Active surveillance in pharmacovigilance might represent the best strategy to estimate and characterize the clinical burden of ADRs in children.
