Trends and off-label utilization of antipsychotics in children and adolescents from 2016 to 2021 in China: a real-world study. Child Adolesc Psychiatry Ment Health 2024; 18:77. [PMID: 38907356 PMCID: PMC11193198 DOI: 10.1186/s13034-024-00766-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Accepted: 06/06/2024] [Indexed: 06/23/2024] Open
Abstract
BACKGROUND Global antipsychotic usage, including off-label prescriptions, has increased in recent decades. However, trends in China, particularly for children and adolescents, remain unclear. This study explored these trends from 2016 to 2021 and identified factors associated with off-label prescriptions. METHODS In this retrospective study, we analyzed on-label and off-label prescriptions based on drug information approved by the China National Medical Products Administration. To identify factors associated with off-label prescriptions, we conducted multivariate logistic regression analysis. RESULTS Our study included 48,258 antipsychotic prescriptions, 52.4% (25,295) of which were prescriptions for males. Of these, 61.7% (29,813) were off-label. Over time, the number of antipsychotics and the percentage of off-label prescriptions for children and adolescents overall increased from 2016 to 2021. The use of atypical antipsychotics increased, whereas that of typical antipsychotics decreased. For off-label usage, all of the factors in our study were associated with off-label usage, including age, sex, year, region, department, reimbursement, antipsychotic type, drug expense, number of polypharmacy and diagnoses. Additionally, tiapride (15.8%) and aripiprazole (18.6%) were the most common typical and atypical antipsychotics, respectively. For pediatric diseases, common diagnoses included mood or affective disorders (31.7%) and behavioral and emotional disorders, with onset usually occurring in childhood and adolescence (29.1%). Furthermore, a depressive state was the most common diagnosis for which antipsychotic polypharmacy was used for treatment. CONCLUSION In this retrospective study, off-label antipsychotic prescriptions were common, with trends generally increasing among children and adolescents from 2016 to 2021. However, there is a lack of evidence supporting off-label usage, thus emphasizing the need for studies on the efficacy and safety of these treatments.

Abstract
BACKGROUND Atopic dermatitis (AD) is a growing burden in all ages. The aim of this study was to compare trial characteristics between pediatric and adult AD trials. METHODS Data were collected from ClinicalTrials.gov on AD therapeutic trials completed between 2003 and 2019. The trials were classified as pediatrics (mean or median age <18 years of the experimental group participants) or adults. The trials with and without results on ClinicalTrials.gov were searched on PubMed for further data collection. RESULTS Of 210 trials, 50 (24%) were pediatric trials [mean age: 8.2 ± 4.3 years (SD)] and 160 (76%) were adult trials [mean age 35.2 ± 5.7 years (SD)]. Pediatric and adult trials were equally likely to be randomized controlled trials; however, pediatric trials were more likely to be open-label trials (P < .001) and have no comparator (P < .001). Adult trials were more likely to be industry-funded (95% vs. 80%, P = .001). Any evaluation of drug safety was more likely present in adult trials (83% vs. 60%, P = .001). In trials examining AD severity as an outcome, the Eczema Area and Severity Index (EASI) predominated in adult trials (51% vs. 29%, P < .05) and Scoring Atopic Dermatitis (SCORAD) in pediatric trials (25% vs. 10%, P < .05). CONCLUSION The results highlight differences in trial design between pediatric and adult AD trials and show a lack of standardization in trial design.

Abstract
Objectives: To determine the differences in information between prescribing guidelines and drug labeling, as well as to compare the approval of psychotropic medicines for major depression in pediatric patients ("pediatric depression") across countries. Methods: The recommendations of The Maudsley Prescribing Guidelines in Psychiatry (MPGP) for the treatment of pediatric depression (<18 years) were compared against the regulatory-approved drug-labeling documents from the United Kingdom, Australia, New Zealand, Canada, and the United States. The use of medicines outside of their regulatory approval is defined as off-label use, so differences between the drug labeling and MPGP were characterized according to unapproved age, indication, dosage, or route of administration. Information in the drug labeling was also compared across countries. Results: MPGP provides recommendations for 6 medicines for the treatment of pediatric depression, for which, 30 drug labeling were retrieved. Three of 30 drug labeling were consistent with MPGP recommendations (fluoxetine in the United Kingdom, fluoxetine and escitalopram in the United States). Differences in information between MPGP and the drug labeling were identified in 26 of 30 drug labeling analyzed, most often due to age (24/26) followed by indication (2/26). No differences pertaining to dosage or route of administration information were identified. The number of approved psychotropic medicines varied across the studied countries and we found cross-country discrepancies in information in the drug labeling. Conclusion: Significant differences in information exists between MPGP and the drug labeling for psychotropic medicines for pediatric depression, due to unapproved ages or indications. Additionally, approval information in the drug labeling are not consistent across countries. Further research into reasons for variability and impact on practice may be warranted.

A Comparison of Pediatric and Adult Safety Studies for Antipsychotic and Antidepressant Drugs Submitted to the United States Food and Drug Administration. J Pediatr 2019; 208:236-242.e3. [PMID: 30679050 PMCID: PMC7171692 DOI: 10.1016/j.jpeds.2018.12.033] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2018] [Revised: 12/08/2018] [Accepted: 12/11/2018] [Indexed: 10/27/2022]
Abstract
OBJECTIVE To examine the differences in the adverse drug reaction (ADR) profile of antipsychotic and antidepressant agents between pediatric and adult patients in studies submitted to the Food and Drug Administration (FDA) during the drug development process. STUDY DESIGN Clinical trials in adult and pediatric patients were conducted by sponsors as part of the drug development programs for antipsychotic and antidepressant agents, and ADR information was collected as part of those trials and submitted to the FDA. Data collection was conducted by reviewing publicly available FDA-authored reviews and FDA-approved product labels for 10 drugs with an antipsychotic or an antidepressant indication from 2007 to 2017. RESULTS There were 308 drug and ADR combinations for the 10 drugs and drug combinations with 113 (36.7%) having a significantly different incidence in pediatric patients compared with adults. Sixty-eight (60.2%) of these ADRs had a significantly higher incidence in pediatric patients than in adults. Sedation was higher in 6 of the 10 drugs and drug combinations with risk differences ranging from 9.6 to 36.6%. CONCLUSIONS This analysis indicates that there were significant differences between the pediatric and adult safety profiles of antipsychotic and antidepressant drugs. Sedation was the major ADR associated with the use of atypical antipsychotic drugs in pediatric patients. Clinicians caring for children should consider the ADR profile when prescribing antipsychotics and antidepressants in pediatric patients.

Abstract
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.
