One of the biggest changes to the electronic common technical document (eCTD) in the past few years was the introduction of the United States Food and Drug Administration’s (USFDA) newest module 1 specifications and corresponding technical files. The new specifications v2.3 and the XML Document Type Definition (DTD) v3.3 were developed to enhance USFDA’s ability to process eCTD submissions and enable additional submission types that were previously not accepted in eCTD format.
After a lengthy testing period, USFDA began accepting submissions using the new v2.3 specifications in June 2015 and has now received thousands of submissions using the new module 1. While uptake has been good, most submissions were applications being submitted to USFDA for the first time, starting from a clean slate with the new specifications.
Transitioning existing applications to the new module 1 adds complexity to eCTD publishing but should not be treated as roadblock. Here we will discuss preparing existing applications for the transition and ways to smooth the process for a successful transition.
