Abstract
Purpose: This study aimed to obtain a better understanding of the characteristics of the risk management plans (RMP) and the background regulatory policies governing them, in the European Union (EU) and Japan. This was done by descriptively comparing the safety concerns (SCs) listed in the RMP and examining their relationships with product labeling.
Methods: Information regarding SCs was collected from the published RMP of both the EU and Japan for the targeted products-all of which were commonly approved in both regions. The concordance rate of the SCs for each product between the EU- and Japan-RMP was calculated. The warning information for each product was collected from the product labeling, summary of product characteristics for the EU, and package insert for Japan, and compared with the SCs listed in the corresponding RMP.
Results: A total of 259 products that were approved for sale in both the EU and Japan (1998-2023), for which RMP were available in both regions, were analyzed. While 51.0% of the SCs labeled as important identified risks (IIRs) in the EU-RMP were concordant with those in the Japan-RMP, 20.4% of the SCs listed as IIRs in the Japan-RMP were concordant with those in the EU-RMP. The concordance rate between the SCs identified as IIRs and the warning information was 18.6% for the EU-RMP and 88.4% for the Japan-RMP.
Conclusions: The low SC concordance rate between the EU- and Japan-RMP indicates a different approach to selecting RMP SCs by the two regulatory authorities.
期刊介绍：
The aim of Pharmacoepidemiology and Drug Safety is to provide an international forum for the communication and evaluation of data, methods and opinion in the discipline of pharmacoepidemiology. The Journal publishes peer-reviewed reports of original research, invited reviews and a variety of guest editorials and commentaries embracing scientific, medical, statistical, legal and economic aspects of pharmacoepidemiology and post-marketing surveillance of drug safety. Appropriate material in these categories may also be considered for publication as a Brief Report.
Particular areas of interest include:
design, analysis, results, and interpretation of studies looking at the benefit or safety of specific pharmaceuticals, biologics, or medical devices, including studies in pharmacovigilance, postmarketing surveillance, pharmacoeconomics, patient safety, molecular pharmacoepidemiology, or any other study within the broad field of pharmacoepidemiology;
comparative effectiveness research relating to pharmaceuticals, biologics, and medical devices. Comparative effectiveness research is the generation and synthesis of evidence that compares the benefits and harms of alternative methods to prevent, diagnose, treat, and monitor a clinical condition, as these methods are truly used in the real world;
methodologic contributions of relevance to pharmacoepidemiology, whether original contributions, reviews of existing methods, or tutorials for how to apply the methods of pharmacoepidemiology;
assessments of harm versus benefit in drug therapy;
patterns of drug utilization;
relationships between pharmacoepidemiology and the formulation and interpretation of regulatory guidelines;
evaluations of risk management plans and programmes relating to pharmaceuticals, biologics and medical devices.
