Commission publishes updated clinical trials guidance package
The European Commission's Directorate-General for Health and Food Safety has published a comprehensive package of updated clinical trials guidance documents, all endorsed by the Clinical Trials Coordination and Advisory Group (CTAG) on 15 October 2025. The package includes new recommendations on criteria for selecting a reporting Member State under Article 85(2)(c) of the Clinical Trials Regulation, establishing a workshare criterion when proposed reporting Member States decline the role, which occurs in approximately 30% of applications. The Commission has updated its recommendation paper on decentralised elements in clinical trials (Version 02), superseding the December 2022 version, with revised national provision overviews and guidance on informed consent, investigational medicinal product delivery, and remote monitoring. A new recommendation paper addresses frequent issues identified during Part I and Part II assessments, based on feedback from national competent authorities and ethics committees, covering investigational medicinal product dossiers, protocols, and safety reporting. The package also includes revised guidance on auxiliary medicinal products, effective 1 December 2025 for new applications, featuring an updated classification system distinguishing between authorised, modified authorised, and unauthorised auxiliary medicinal products with corresponding application and safety reporting requirements.
