eCTD Structure

The electronic Common Technical Document (eCTD) structure consists of five modules that comprise the agreed upon set of application dossier specifications for pharmaceuticals that are designed to be registered and sold in Europe, Japan, the United States, and any geographic region that utilizes the CTD structure.

The initial eCTD structure was first proposed by the International Conference on Harmonisation (ICH) working committee in the 1990s before being agreed upon by participating nations in the year 2000. The U.S. Food and Drug Administration (FDA) was the first regulatory body to adopt the common CTD structure for receiving product registration submission from companies. While the processes involved in registrations have been streamlined over the years, they can be made significantly more efficient by implementing automated solutions that are specially designed to align processes and document management with the established, agreed upon CTD structure.
