The document discusses the Investigational Medicinal Product Dossier (IMPD) which contains detailed information on the quality, manufacture, and control of investigational medicinal products tested in clinical trials within the European Union. The IMPD is submitted as part of clinical trial authorization applications to regulatory authorities. It includes summaries of non-clinical and clinical data and a risk-benefit assessment. The IMPD requirements are harmonized across EU member states under regulations established by the European Medicines Agency to facilitate multinational clinical trials.
