CTD (Common Technical Document): A standardized format developed by ICH (International Council for Harmonisation) for organizing and submitting pharmaceutical product registration dossiers. It consists of five modules covering administrative information, summaries, quality, non-clinical, and clinical data. CTD can be submitted in paper format.
eCTD (Electronic Common Technical Document): The electronic version of the CTD, which follows the same module structure but is submitted digitally. eCTD allows for easier review, updates, and lifecycle management of submissions. It is now mandatory for submissions to the FDA, EMA, and increasingly other global regulatory authorities.
Medwisdom Lifescience provides expert preparation and submission support for both CTD and eCTD formats.
