The Common Technical Document (CTD) is a set of specifications for an application dossier for the registration of Medicines and designed to be used across Europe, Japan and the United States and beyond. Synopsis The CTD is an internationally agreed format for the preparation of applications regarding new drugs intended to be submitted to regional regulatory authorities in participating countries. It was developed by the European Medicines Agency (EMA, Europe), the Food and Drug Administration (FDA, US) and the Ministry of Health, Labour and Welfare (Japan) starting at the World Health Organization International Conference of Drug Regulatory Authorities (ICDRA) at Paris in 1989. The CTD is maintained by the International Council on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). After the United States, European Union and Japan, the CTD was adopted by several other countries including Canada and Switzerland. The Paper CTD is destined to be replaced by its electronic counterpart, the eCTD. Document contents The Common Technical Document is divided into five modules: Administrative and prescribing information Overview and summary of modules 3 to 5 Quality (pharmaceutical documentation) Preclinical (Pharmacology/Toxicology) Clinical – efficacy and safety (Clinical Trials) Detailed subheadings for each Module are specified for all jurisdictions.
